铝塑板厚度：复合板是由内外两面铝合金板、低密度聚乙烯芯层与粘合剂复合为一体的一种新型 金属 塑料复合墙面装饰材料，由于其具有防火、耐酸、耐冲击、可弯曲、可钉刨、施工简便、易清洗等特点，具有很强的抗风、抗弯强度以及良好的隔音、隔热性能。铝塑复合板是一种新型的生态环境建筑材料，广泛应用于建筑幕墙、室内装修、广告宣传、汽车装饰、家具制造等领域，被建筑师们称为继石材（陶瓷、砖）、玻璃之后的第三代幕墙材料。　　铝塑复合板在我国的生产始于20世纪90年代，经过近10年的发展，已在 市场 认知度、 产量 、品种、工艺、质量、标准、应用等各方面都取得了显著进步。据不完全统计，自1998年以来，铝塑复合板年 产量 以近30%的速度增长。到2002年，铝塑复合板年 产量 已超过5000万平米，年产值超过100亿元人民币，并已形成一定规模的出口能力。可以说，铝塑复合板已经作为一个 产业 在中国蓬勃发展。　　铝塑板厚度大致可分室外、室内用两种，再可分为防火型和一般型。现在 市场 大量销售的均为一般型。室外用铝塑复合板上下均为0.5mm铝板（一般为纯铝板），中间夹层为PE（聚乙稀）或PVC（聚氯乙烯），夹层厚度为3-5mm。防火型铝塑复合板中间夹层为FR（防火塑胶）。室外用复合铝塑板厚度为4-6mm。室内用铝塑板上下面一般为0.2-0.25mm铝板，夹层厚度为2.5-3mm，室内用铝塑板厚度为3-4mm。铝塑板产品标准规格一般为1220（宽）x2440（长）x厚度，宽度也可以达到1250或1500mm。室外常采用厚度最薄应为4mm，室内采用厚度应力为3mm。

铝板厚度:（冷轧 热轧）材质1系3系5系6系7系8系 模具铝板厚度　0.1mm---260mm宽度　800mm----1900mm铝板，顾名思义是指用铝材或铝合金材料制成的板型材料。或者说是由扁铝胚经加热、轧延及拉直或固溶时效热等过程制造而成的板型铝制品。铝板的用途　　1.照明灯饰2、太阳能反射片3、建筑外观4、室内装潢：天花板，墙面等5、家具、橱柜6、电梯7、标牌、铭牌、箱包8、汽车内外装饰9.室内装饰品：如相框10、家用电器：冰箱、微波炉、音响设备等11.航空航天以及军事方面，比如中国目前的大飞机制造，神舟飞船系列，卫星等方面。铝板的分类以及用途　根据合金元素含量不同铝板可以分为8个系列分别为 1***，2***，3***，4***.5***.6***.7***.8*** 　　根据加工工艺不同又可分为冷轧和热轧。根据厚度不同可以分为薄板和中厚板。GB/T3880-2006标准中规定 厚度0.2毫米以下的称为铝箔。一般常常指单层铝板(也有叫单铝板或纯铝板),建筑上使用的铝板包括单层铝板、复合铝板等多种材料.多用于建筑装饰工程中,近年来在铝板幕墙中单层铝板使用的较为多见.铝板幕墙也是幕墙的一种形式,简单地说是用铝板代替玻璃制成幕墙,铝板幕墙多用于作墙体蔽护和不采光的墙壁.如广州世界贸易中心,就用了西南铝加工厂板材分厂加工好不同弧度的铝板近一百五十吨,表面采用静电喷涂.　为了加强铝板板面强度,国外的铝板幕墙一直选用单层铝板.单层铝板一般用纯铝板.铝板厚度为3mm.铝板的背面,必须安装加强筋(现有的厂家不安),加强筋用厚的铝带做成先用闪光焊机把一颗颗螺丝帽铝板焊在铝板背面然后把作加强筋的铝条钻孔套进螺丝内用螺丝固定.国为了减轻铝板重量增加铝板强度.采用铝合金板常选用21号防锈铝代号LF21压成的铝板作幕墙铝板.铝板厚度由原来3mm减少为2.5mm该合金强度比纯铝板高出一倍左右.铝带的宽度厚度根据铝板板面而定.加强筋用LF21铝带.一般厚2-2.5mm宽10-25mm.铝板幕墙的铝板背面为什么要安加强筋外界正负压力的情况下铝板一不会凹陷二不会鼓出.  这样就避免了铝板幕墙反复里外振动而发出的振动声音.如果需要隔音保温可在铝板内侧安放岩棉矿渣棉或发泡处理铝板，重庆西南铝深加工厂,国内第一家生产铝板幕墙的铝板厂家.该厂为军品厂家,生产的铝板宽度可达到2.8米.可分为二种方法,幕墙铝板表面处理.一种是阳极氧化,另一种是静电喷涂.阳极氧化的氧化膜一般在12m以上.　 更多有关铝板厚度信息请详见于上海 有色 网

美国机械工程师协会(ASME) 负责制订、颁布和实施的锅炉压力容器技术规范,它不仅是统一的美国国家标准, 同时也是国际公认的标准法规系统。ASME 规范第II 卷材料篇,主要引用了美国材料试验学会(ASTM) 的相应材料标准和材料试验标准。在ASME 规范中允许使用的材料一般来说必须按照第II 卷的材料标准供货。因此,只有认真研究ASME 材料标准,并与我国锅炉钢板标准进行对比与分析,找出之间的差距,才能建立适合我国超临界火电机组发展的完善的锅炉用钢板标准和标准体系。 1 　常用锅炉钢板及性能要求 从材料上来分,锅炉钢板可分为专用碳素钢板和低合金耐热钢板两类。锅炉钢板所用的材料对化学成分,特别是对磷、硫等有害元素和铬、镍、铜等残余元素有严格的控制;冶炼时还应进行良好的脱氧和去除非金属夹杂物,以保证良好的塑性和韧性;组织结构要求均匀,晶粒度控制在一定范围内(通常希望晶粒度在3～7 级之间);对表面质量和内部缺陷也有严格的要求;此外常温和高温力学性能必须保证。 根据工作条件不同,锅炉钢板又可分为制造室温及中温承压部件钢板和制造高温承压部件钢板两大类。 室温及中温(蠕变温度以下) 用锅炉钢板,大多采用碳素钢,包括碳钢、碳锰钢、碳锰硅钢等,即GB713  -1997 锅炉用钢板中的20g 、22Mng 、16Mng 、19Mng 钢,以及美国ASME SA -515ΠSA -515M 中高温压力容器用碳钢板、SA-299ΠSA -299M 压力容器用碳锰硅钢板等。主要用于制造锅炉的锅筒、中温以下集箱端盖等承压部件。要求其应具有较高的室温强度;良好的冲击韧性和较低的缺口敏感性;由于锅筒等部件在加工时需要大量的冷变形,因此还要具有良好的时效韧性;另外还要具备良好的加工工艺性和焊接性能;以及良好的低倍组织等。 高温(蠕变温度以上) 用锅炉钢板,一般采用低合金耐热钢,常用有铬钼钢、铬钼钒钢、铬钼钨钢等。例如GB713 -1997 锅炉用钢板中的15CrMog 、12Cr1MoVg , 以及美国ASME SA -387ΠSA387 -M 压力容器用铬-钼合金钢板中的Gr22 、Gr91 和ASME SA -1017ΠSA1017 -M 压力容器用铬-钼-钨合金钢板中的Gr23 、Gr911 、Gr122 钢等。主要是用以制造高温集箱封头端盖、蒸汽管道堵板等高温承压部件。要求 其必须具有足够的高温持久强度和持久塑性;良好的高温组织稳定性;良好的高温抗氧化性(耐热性);以及良好的冷热加工工艺性(主要指冷弯变形和可焊接性) 等。 2 　锅炉钢板标准对比分析 对锅炉制造行业来说,ASME 无疑是世界上最权威、最先进、最完善的建造规范。我国的锅炉行业在引进超临界火电机组锅炉的制造技术时,几乎无一例外的采用了美国机械工程师协会(ASME) 制订、颁布和实施的锅炉压力容器技术规范。 现阶段我国的锅炉钢板标准体系分为通用标准和产品标准两层,通用标准包括GBΠT247 钢板和钢带检验、包装、标志及质量证明书的一般规定和GBΠ T14977 热轧钢板表面质量的一般要求两个标准,产品标准仅GB713 锅炉用钢板1 个标准。另外我国还有一个压力容器钢板标准GB6654 压力容器用钢板, 但因为其与大型火电机组锅炉用钢板的要求相距甚远,因此不适合高压以上大型火电机组锅炉上使用。 美国ASME 规范第II 卷材料A 篇(铁基材料) 中, 有关锅炉和压力容器用钢板标准共约44 个,虽然在标准名称上都称作“压力容器用钢板”,但在每一个标准中的第一部分“适用范围”中,对本标准适用于锅炉还是压力容器,都做了明确的规定。所以适用于锅炉用钢板的标准大约有9 个,按体系也可以分为两层, 即通用标准1 个SA-20ΠSA-20M 压力容器用钢板通用要求和产品标准8 个SA-202ΠSA -202M 压力容器用铬锰硅合金钢板、SA-204ΠSA -204M 压力容器用钼合金钢板、SA-299ΠSA -299M 压力容器用碳锰硅钢板、SA-302ΠSA -302M 压力容器用锰钼和锰钼镍合金钢板、SA-387ΠSA -387M 压力容器用铬钼合金钢板、SA-515ΠSA -515M 中高温压力容器用碳钢板、SA-516ΠSA -516M 常低温压力容器用碳钢板、SA -1017ΠSA -1017M 压力容器用铬钼钨合金钢板。另外所有ASME 材料的物理性能、使用温度和许用应力等数据,都集中放在ASME 规范第II 卷D 篇材料性能当中,使用和查找十分便利。 通过对比ASME 锅炉钢板标准及体系可以看出, 我国锅炉钢板产品标准GB713 锅炉用钢板中,将不同品种和不同使用要求的锅炉钢板,以及锅炉钢板的一般性能和高温特殊性能等都放在一起表述,篇幅烦琐,对锅炉钢板的性能要求体现不够。ASME 锅炉钢板标准的制订是按材料加以区分的,每一类材料制订 　第4 期　　　　　　　　　　　　　　　中美锅炉钢板标准的对比及发展 一个标准。标准内容除了规定了这一类材料的基本性能外,对具体用途和注意事项,以及协议条款等,在标准中都有非常详细的规定,充分体现了对锅炉钢板的性能要求,技术性突出,贸易性明显。标准体系和内容非常清晰,让人一目了然。用户在选择和使用上也很方便。 因此,现阶段我国的锅炉钢板标准及体系应加大力度重新予以制修订,以适应先进的超临界锅炉技术的发展对锅炉钢板的要求。 3 　锅炉钢板标准发展探讨 上世纪80～90 年代,我国电力制造行业成功地引进了亚临界参数锅炉技术。为适应亚临界压力以下锅炉对锅炉钢板的要求,由鞍山钢铁集团公司、冶金工业信息标准研究院等单位,对GB713 -86 锅炉用碳素钢和低合金钢钢板进行了重新修订。新修订并一直沿用至今的锅炉钢板标准为GB713 -1997 锅炉用钢板。在这个版本中,除了20g 和16Mng , 新增加了用于制造锅筒的19Mng (等同于德国标准19Mn6) 、22Mng (等同于美国标准SA299) 、13MnNiCrMoNbg (等同于德国标准BHW355) 等三个牌号,以及用于高温集箱端盖及支吊架等部件的15CrMog 、12Cr1MoVg 两个耐热钢牌号,其他内容也做了一定的修改。新修订的GB713 -1997 锅炉用钢板,不仅基本上满足了亚临界压力以下锅炉锅筒、集箱端盖及其支吊件的要求, 为我国电力事业的发展做出了突出贡献,而且还带动了我国钢铁行业的技术进步和产品质量的提高。 进入本世纪以来,随着世界上超临界参数火电机组的发展,我国也开始引进并大量设计制造超临界参数火电机组。超临界火电机组锅炉大多采用直流循环,螺旋炉膛,用汽水分离器替代了锅筒汽包,锅炉中集箱的温度和压力更高,更多的使用一些新型的、性能优异的耐热合金钢。由于对锅炉钢板的性能提出了新的要求,因此一直沿用的GB713 -1997 锅炉用钢板标准,其中的一些内容和技术指标,无论是与国外先进水平标准相比,还是与锅炉行业发展的相关要求相比,均存在着一定的差距,主要体现在下述几个方面:  3. 1 　标准水平 锅炉钢板产品标准GB713 -1997 锅炉用钢板,采用国际先进标准力度远远不够,标准水平只达到了国际一般水平。由于锅炉钢板标准属于重要用途的产品标准,安全可靠性要求严格,制造技术难度高,而且产量比较大。随着我国钢铁行业的生产技术和产品质量的不断提高,锅炉钢板标准应继续采用国际先进标准,加强采标力度,不断提高标准水平。 由于我国锅炉钢板产品标准只有一个,因此可以按照ASME 规范第II 卷D 篇材料性能的模式,制订一份有关我国锅炉钢板材料力学性能和物理性能的通用标准,也可以将这些材料性能完全放在产品标准GB713 中,包括锅炉设计选材时必须用到的高温规定非比例延伸强度(Rp0. 2) 、高温持久强度等力学性能, 以及常用的热膨胀系数、弹性模量等物理性能。另外如有可能,还可参照ASME 的方法,按不同材料、用途和性能,将锅炉用钢板标准细分成若干个标准(如专用碳素钢板、低合金耐热钢板等),以适应用户的需要和应用。 3. 2 　外形尺寸 由于我国钢铁行业技术和装备水平的制约,锅炉用的宽厚钢板还几乎无法生产。GB713 仅适用于厚度6～150mm 的范围,而亚临界锅炉锅筒用的钢板厚度一般都在160～210mm 之间,只能依靠进口解决。我们只有提高那些重要用途、技术含量高的产品标准的水平,才有利于带动整个钢铁工业技术进步和产品质量提高,才能最终实现国产化,摆脱进口的束缚。 近年来,钢铁行业在国家良好的经济发展形式下,正大幅度的提高整体技术和装备水平。“十五”规划建设的宝钢5 000mm 宽厚板轧机工程项目,建成投产后其生产的锅炉钢板厚度可达到5～400mm 。作为我国第一套现代化的特宽幅宽厚板轧机,它的建设将带动我国宽厚板生产技术的跳跃式发展,对提升我国宽厚板产品档次,增强我国的综合国力,将发挥积极作用。我们应抓住国内钢铁技术和锅炉制造技术取得突破性进步这个机会,将新技术和新要求纳入锅炉钢板标准,并向国际先进水平标准靠拢,提高我国锅炉钢板标准的技术水平。 3. 3 　材料牌号 材料标准和技术条件是材料应用的载体。随着火电机组参数的提高,锅炉制造水平不断进步,ASME 会随着每三年一次修订和每年的增补, 根据建造ASME 规范产品的需要和冶金技术的发展,适当地在原有钢种基础上新纳入和增加代表当今世界最新材料技术水平的新型材料。例如,为适应超临界锅炉集箱封头端盖和支吊架等部件对耐热钢板的要求,最新的2004 版ASME 规范第II 卷材料A 篇中,新制订了SA -1017ΠSA -1017M 压力容器用铬-钼-钨合金钢板标准。我国锅炉用钢板标准在新型材料的纳标上炉钢板材料几乎没有纳入。显得滞后,往往跟不上锅炉制造技术的发展,现行的GB713 -1997 锅炉用钢板与ASME 锅炉钢板标GB713 -1997 锅炉用钢板已经使用了8 年之久,材料准中材料牌号之间的对比,见表1 所示。品种偏少,供用户选择的余地小,特别是高温用的锅

通过表1 对比可以看出,用于室温及中温(蠕变温度以下) 的碳锰系列锅炉钢板, GB713 共收纳了5 个牌号,可以满足亚临界以下火电机组锅炉中汽包锅筒、水冷壁集箱端盖、以及低温过热器和省煤器集箱端盖、支吊架等零部件的需要。对于ASME 中的锰铬、锰钼等系列标准中的钢板牌号,我国火电机组锅炉基本不使用,因此不需要纳入我国锅炉钢板标准。用于高温( 蠕变温度以上) 的铬钼系列锅炉钢板, GB713 -1997 中牌号只有2 个。其中15CrMog 最高使用温度为550 ℃,12Cr1MoVg 最高使用温度为565 ℃。而超临界火电机组锅炉中的高温过热器和再热器集箱等部件的金属壁温已经达到600 ℃以上,15CrMog 和12Cr1MoVg 已经达不到要求,因此应将ASME 标准中那些可以使用在600 ℃及以上的材料SA -387Gr22Π 22L 、SA -387Gr91 、SA -387Gr911 、SA -1017Gr122 等, 纳入我国的锅炉用钢板标准,以适应超临界火电机组锅炉技术的发展,提升我国冶金和机电产品的整体水平。 3. 4 　技术要求GB713 -1997 规定的技术要求,与ASME 锅炉钢板标准中规定的技术要求对比,见表2 。 从表2 中可以看出,ASME 锅炉钢板标准中的技术要求,除了化学成分和基本的力学性能必须保证外,其余大多是供不同的用户在不同的使用中,对钢板的技术要求做出不同选择的协议项目。ASME 充分体现了以市场为导向,以用户需求为目标的世界先 　第4 期　　　　　　　　　　　　　　　中美锅炉钢板标准的对比及发展 进标准的指导思想。而我国的锅炉用钢板标准显得微量元素、冶炼、锻造、热处理、金相组织等各种因素计划经济体制痕迹较重,起草和制修订标准时,对标的变化而变化的,它是一个帮助分析、判断材料的工准所使用的行业特点没有清楚的反映出来,对用户真艺和质量水平的有效方法。另外,当锅炉运行一段时正需要的技术要求和保证条款调查和重视不够,没有间后,通过材料的冷脆转变温度的变化情况,还可以达到生产型标准向贸易型标准转变的功效。帮助预测锅炉的运行寿命。因此在GB713 当中,应 根据表2 的对比分析发现,ASME 钢板标准都将将落锤试验或系列冲击试验,以及铬钼钢的硬度试验落锤试验作为钢板技术要求中的协议项目,这是因为等作为协议条款给出,方便用户在不同的使用条件下锅炉钢板冷脆转变温度的高低是随材料的化学成分、进行选择。 表2 　GB713 与ASME 锅炉钢板技术要求对比

材料是火电机组锅炉建造的基础和技术核心之一。美国ASME 规范把材料及其标准列为第二卷,作为整个规范的一个重要组成部分。ASME 钢材标准不仅是钢材生产部门的质量标准,而且是钢材使用单位(设计、制造、检验) 在选用、采购、验收、检验、加工时的依据。ASME 钢材标准是在市场经济模式下,由供需双方共同编制,且以反映钢材使用者的要求为主的标准。ASME 锅炉钢板标准看似十分繁多,但仔细分析却又体系明确、联系紧密、互相呼应、配套性强, 是锅炉建造中不可缺少的一部分。 相对比较而言,我国锅炉钢板仅有GB713 一个标准,其中的材料品种、牌号、等级等,都远远少于ASME 规范,使用上受到很大局限性。另外,我国过去是在计划经济体制下,主要以供方为主编制钢材质量标准,没有更全面地反映钢材使用者的要求和反映锅炉建造的要求,因此锅炉钢板标准在许多方面还不能满足用户需求。 中国锅炉制造行业和冶金行业需要共同努力,深入分析、理解ASME 规范等世界先进标准,找出我国锅炉钢板标准的不足,明确发展方向。今后应继续加大采用国际标准和国外先进标准的力度,积极促进ASME 规范中国化和ASME 钢材国产化,制修订出适合我国火电机组锅炉技术发展的先进的锅炉钢板标准,提升我国锅炉制造行业和冶金行业的整体水平, 更好的为经济建设服务。

不锈钢厚度测量/不锈钢厚度 不锈钢管是一种中空的长条钢材，大量用作输送流体的管道，如石油、天燃气、水、煤气、蒸气等，另外，在搞弯、抗扭强度相同时，重量较轻，所以也广泛用于制造机械零件和工程结构。也常用作生产各种常规武器。分类：钢管分无缝钢管和焊接钢管（有缝管）两大类。按断面形状又可分为圆管和异形管，广泛应用的是圆形钢管，但也有一些方形、矩形、半圆形、六角形、等边三角形、八角形等异形钢管。 对于承受流体压力的钢管都要进行液压试验来检验其耐压能力和质量，在规定的压力下不发生泄漏、浸湿或膨胀为合格，有些钢管还要根据标准或需方要求进行卷边试验、扩口试验、压扁试验等的分类：钢管分无缝钢管和焊接钢管（有缝管）两大类。按断面形状又可分为圆管和异形管，广泛应用的是圆形钢管，但也有一些方形、矩形、半圆形、六角形、等边三角形、八角形等异形钢管。 对于承受流体压力的钢管都要进行液压试验来检验其耐压能力和质量，在规定的压力下不发生泄漏、浸湿或膨胀为合格，有些钢管还要根据标准或需方要求进行卷边试验、扩口试验、压扁试验等。 无缝不锈钢管也称不锈钢无缝管,是用钢锭或实心管坯经穿孔制成毛管，然后经热轧、冷轧或冷拨制成。无缝钢管的规格用外径*壁厚毫米数表示。 不锈钢管的厚度公差为+0.01mm,-0.02mm。合同中未注明的以此标准执行！ 不锈钢厚度 也就是按支结算的，价格按照合同厚度计算，生产按照国家标准执行！ 如果合同中注明了实际厚度，在计算重量和价格时，厚度按照+0.02mm计算。 不锈钢板的尺寸规格 通用尺寸：1000*2000、1219*2438、1500*6000、1800*6000 普通定尺：1000*定尺、1219*定尺、1500*定尺、1800*定尺 任意定尺（一般价格会较高） 以上单位均为mm

镀锌的镀层厚度（coating thickness），是指钢铁表面上锌和(或)锌合金镀层的总厚度，以km表示。镀锌的镀层局部厚度（local coating thickness），在某一基本测量面按规定次数用磁性法所测得的镀层厚度的算术平均值或用称量法进行一次测量所测得的镀层镀覆量的厚度换算值。镀锌的镀层平均厚度（mean coating thickness ），对某一大件或某一批镀锌件抽样后测得镀层局部厚度的算术平均值。镀锌是指在装有镀件、玻璃球、锌粉、水和促进剂的旋转滚桶内，作为冲击介质的玻璃球随着滚桶转动，与镀件表面发生摩擦和锤击产生机械物理能量，在化学促进剂的作用下，将镀涂的锌粉“冷焊”到镀件表面上，形成光滑、均匀和细致的具有一定厚度的镀层。我们通常用镀锌量来表示镀锌钢材的镀锌厚度，一个普遍采用的有效方法，镀锌量的单位为g/m2。镀锌镀层厚度的作用和影响：镀锌镀层的厚度决定了镀件的防腐蚀性能。可以选择高于或低于标准的锌镀层厚度。对于表面光滑的3mm以下薄钢板，工业生产中得到较厚的镀层是困难的，另外，与钢材厚度不相称的锌镀层厚度会影响镀层与基材的结合力以及镀层外观质量。过厚的镀层会造成镀层外观粗糙，易剥落，镀件经不起搬运和安装过程中的碰撞。

船用钢板指按船级社建造规范要求生产的用于制造船体结构的热轧钢板材。  　　由于船舶工作环境恶劣，船体壳要受海水的化学腐蚀、电化学腐蚀和海生物、微生物的腐蚀；船体承受较大的风浪冲击和交变负荷；船舶形状使其加工方法复杂等因素、所以对船体结构用钢要求严格。首先良好的韧性是最关键的要求，此外，要求有较高的强度，良好的耐腐蚀性能、焊接性能，加工成型性能以及表面质量。为保质量和保证有足够的韧性，要求化学成分的Mn/C在2.5以上，对碳当量也有严格要求，并由船检部门认可的钢厂生产。船体用结构钢按照其最小屈服点划分强度级别为：一般强度结构钢和高强度结构钢。船体用结构钢分一般厚度和高强度钢两种，一般强度钢按质量分A、B、C和D四个等级；高强度钢又分两个强度级别和三个质量等级；AH32、DH32、EH32、AH36、DH36、EH36。  　　中国船级社规范标准的一般强度结构钢分为：A、B、D、E四个质量等级（即CCSA、CCSB、CCSC、CCSD）；中国船级社规范标准的高强度结构钢为三个强度级别、四个质量等级。  　　主要船级社规范有： 船用钢板　　中国 CCS  　　美国 ABS  　　德国 GL  　　法国 BV  　　挪威 DNV  　　日本 KDK  　　英国 LR  　　船体用结构钢的化学成分  　　钢  　　类 等级 化学成份（质量分数）（%）  　　C Mn si P S Al Nb V  　　一般  　　强度  　　钢 A ≤O.22 ≥2.5C O.10～0.35 ≤O.04 ≤0.04  　　B ≤O.21 O.60～1.00  　　D ≤O.21 0.60～1.00 ≥O.015  　　E ≤O.18 O.70～1.20 ≥0.015  　　高  　　强  　　度  　　钢 AH32 ≤O.18 O.70～1.60 0.10～O.50 ≤O.04 ≤0.04 ≥O.015  　　DH32 O.90～1.60  　　EH32 O.90～1.60  　　AH36 0.70～1.60 O.015～O.050 O.03O～O.10  　　DHB6 0.90～1.60  　　EH36 O.90～1.60  　　船体用结构钢的交货状态  　　钢材等级 厚度／mm 交货状态  　　A 6---40  　　热轧、控轧或正火  　　B 热轧、控轧或正火  　　D 6---32 热轧、控轧或正火  　　正火①②  　　E 6---32 钢板：正火；型钢；正火或控轧  　　AH32  　　AH36 6---32  　　>25--32 热轧、正火或控轧  　　正火①②  　　DH32  　　DH36 6---25  　　>20---32 正火或控轧②  　　正火①②  　　EH32  　　EH36 6---40 正火②  　　船体用结构钢的力学性能  　　钢材  　　等级  　　厚度  　　／mm  　　屈服点 ós  　　／MPa 抗拉  　　强度  　　ób／MPa 伸长率δ5  　　(％) v型冲击试验 冷弯试验  　　温度  　　／℃ 平均冲击吸收功  　　AKv／J 窄冷弯  　　b=2a  　　180℃ 宽冷弯  　　b=5a  　　120°  　　纵向 横向  　　≥ ≥ ≥  　　A ≤50 235 400～490 22 d=2a  　　B 0 27 20  　　d=3a  　　D —10 27 20  　　E 一40 27 20  　　AH32 ≤50 315 440～590 22 O 3l 22  　　d=3a  　　DH32 —20 31 22  　　EH32 —40 31 22  　　AH36 ≤50 355 490～620 21 O 34 24  　　d=3a  　　DH36 —20 34 24  　　EH36 —40 34 24  一般强度船体结构用钢分为A、B、C、D4个等级，这4个等级的钢材的屈服强度（不小于235N/mm^2）和抗拉强度（400～520N/mm^2）一样，只是不同温度下的冲击功不一样而已； 高强度船体结构用钢按其最小屈服强度划分强度等级，每一强度等级又按其冲击韧性的不同分为A、D、E、F4级。 A32、D32、E32、F32的屈服强度不小于315N/mm^2，抗拉强度440～570N/mm^2，A、D、E、F分别表示其各自可分别在0°、-20°、-40°、-60°的情况下所能达到的冲击韧性； A36、D36、E36、F36的屈服强度不小于355N/mm^2，抗拉强度490～620N/mm^2，A、D、E、F分别表示其各自可分别在0°、-20°、-40°、-60°的情况下所能达到的冲击韧性； A40、D40、E40、F40的屈服强度不小于390N/mm^2，抗拉强度510～660N/mm^2，A、D、E、F分别表示其各自可分别在0°、-20°、-40°、-60°的情况下所能达到的冲击韧性。 还有， 焊接结构用高强度淬火回火钢：A420、D420、E420、F420；A460、D460、E460、F460；A500、D500、E500、F500；A550、D550、E550、F550；A620、D620、E620、F620；A690、D690、E690、F690； 锅炉与受压容器用钢：360A、360B；410A、410B；460A、460B；490A、490B；1Cr0.5Mo、2.25Cr1Mo 机械结构用钢：一般可选用上述钢材； 低温韧性钢：0.5NiA、0.5NiB、1.5Ni、3.5Ni、5Ni、9Ni； 奥氏体不锈钢：00Cr18Ni10、00Cr18Ni10N、00Cr17Ni14Mo2、00Cr17Ni13Mo2N、00Cr19Ni13Mo3、00Cr19Ni13Mo3N、0Cr18Ni11Nb； 双相不锈钢：00Cr22Ni5Mo3N、00Cr25Ni6Mo3Cu、00Cr25Ni7Mo4N3。 复合钢板：适用于化学制品运输船的容器和液货舱； Z向钢：是在某一等级结构钢（称为母级钢）的基础上，经过特殊处理（如钙处理、真空脱气、氩气搅拌等）和适当热处理的钢材。 a

它是热轧钢板、镀锌钢板上涂0.4-0.5mm的软质或半硬质聚氯乙烯塑料薄膜制成，具有耐热、耐腐蚀性能，可做墙板。 　　彩色涂层钢板简述: 　　在钢板上涂上有机涂料，涂料可以有各种不同的颜色，彩色涂层钢板由此而得名，简称彩板，也称有机涂层钢板。由于彩色涂层钢板是在钢板加工成型前先涂上涂料，在国外也称为预涂层钢板。彩涂板有机涂层起了覆盖隔离作用，可防止钢板生锈，使用寿命更长。 　　彩涂板的基板有冷轧基板、热镀锌基板、电镀锌基板、热镀铝锌基板。　　彩涂板的面漆涂层种类可以分为：聚酯、硅改性聚酯、偏聚氟乙烯、高耐久性聚酯等。　　生产工艺从一涂一烘发展到二涂二烘，也出现三涂三烘的工艺。　　彩涂板的表面状态可以分为正常涂层板、压花板、印花板等。 　　彩涂板主要用途分为建筑、家电和交通运输等。由于彩涂板不仅色彩鲜艳，还具有优良的成型性和耐久性，使用寿命长等优点，还大量节省客户的清洗脱脂和油漆作业的设备成本和人工。因此，彩色涂层钢板已广泛应用在我国的建筑业（大型工业厂房、大型仓库、简易活动室、室内装饰板、机场建筑物、现代化大型飞机库、大型体育馆等）预热隔热夹芯板、大型冷藏库、彩涂钢板制门窗、卷帘门及钢制家具。在家电行业中用于冰柜、洗衣机。电子工业应用在仪表开关箱外壳、录音机机芯等。其它如候车厅，售票亭，办公室隔墙等，应用正不断扩大。　　PCM彩板即连续辊涂彩色钢板，其色彩鲜艳，不仅具有良好的成型加工性、漆膜耐腐蚀性和柔韧性，又具有良好的经济效益，满足社会经济、环保发展的要求。根据ECCA（欧洲卷涂协会）数据统计，PCM彩板在生产效率、周转储存、环保效应、外观效果方面均优于传统的喷粉板材，其综合成本仅相当于喷粉板材的90%左右，因此，在欧美地区家电外装饰材料几乎都采用该类彩板；目前在国内，以海尔集团为代表，喷粉板材正逐渐被彩板所取代。　　在传统PCM彩板的基础上，海尔彩板公司通过整合全球资源，研制开发出导电PCM彩板及辊涂工艺的砂面PCM彩板，成为国内唯一的砂面PCM彩板的生产基地。产品不仅符合欧盟的ROHS环保标准，且经国家科委、经贸委鉴定，产品性能品质均已达到国际领先水平。　　彩色予涂钢板PCM,将传统的喷涂涂装变成钢板的连续涂布，便于表面处理及涂布质量的控制，又不存在涂装易产生的棱边死角等缺陷；而且采用无铬处理液进行辊涂式化学处理后直接干燥，无传统浸涂式化学处理对环境的污染和破坏，满足环保要求。 　　产品特点： 　　彩色予涂钢板PCM板材色彩鲜艳，既具有钢板的强度和良好的成型加工性，又能够满足高速、精密加工设备的要求。而PCM得以高速发展的主要原因，其具有良好的经济效益同时也能满足社会经济、环保发展的要求。　　在连续机组上以冷轧带钢，镀锌带钢（电镀锌和热镀锌）为基板，经过表面预处理（脱脂和学处理），用辊涂的方法，涂上一层或多层液态涂料，化经过烘烤和冷却所得的板材即为涂层钢板。由于涂层可以有各种不同的颜色，习惯上把涂层钢板叫做彩色涂层钢板。又由于涂层是在钢板成型加工之前进行的，在国外这叫做预涂层钢板. 　　工艺流程 　　彩色涂层钢板是以冷轧钢板和镀锌钢板为基板，经过表面预处理（脱脂、清洗、化学转化处理），以连续的方法涂上涂料（辊涂法），经过烘烤和冷却而制成的产品。 　　常见的二涂二烘型连续彩色涂层机组工艺流程主要生产工序为：开卷→预处理→涂敷→烘烤→后处理→卷取。 　　产品用途： 　　涂层钢板具有轻质、美观和良好的防腐蚀性能，又可直接加工，它给建筑业、造船业、车辆制造业、家具行业、电气行业等提供了一种新型原材料，起到了以钢代木、高效施工、节约能源、防止污染等良好效果。使用镀锌钢板为基板的彩色涂层钢板，除有锌保护外，锌层上的有机涂层起了覆盖隔离作用，可防止钢板生锈，使用寿命比镀锌钢板更长，据介绍涂层钢板的使用寿命比镀锌钢板长50%。 　　但是，在不同的地区和不同的使用部位，采用相同镀锌量、同种涂料、相同涂层厚度的彩色涂层板，其使用寿命会有很大的不同。例如，在工业区或沿海地区，由于受到空气中二氧化硫气体或盐分的作用，腐蚀速度加快，使用寿命受到影响。 　　在雨季，涂层长期受雨水浸湿、或者在日夜温差太大易结露的部位，都会较快地受到腐蚀，使用寿命均会降低。 　　用彩色涂层钢板制造的建筑物或厂房，经常受到雨水冲洗时使用寿命较长，否则，由于受二氧化硫气体、盐和灰尘的作用而影响使用。因此，在设计时，若屋顶的倾斜度越大，则越不容易积聚灰尘等污物，使用寿命越长；对于那些不受雨水经常冲洗的区域或部位，应定期用水冲洗。　　彩涂钢板分类 　　彩色涂层钢板产品可以采用冷轧基板、热镀锌基板和电镀锌基板。 　　按基板分类的彩色涂层钢板种类如下： 　　彩 色 涂 层 钢 板 　　冷轧基板彩色涂层钢板 　　热镀锌彩色涂层钢板 　　热镀铝锌彩色涂层钢板 镀5%铝锌彩色涂层钢板 　　镀55%铝锌彩色涂层钢板 　　电镀锌彩色涂层钢板 　　其它 印花彩板 　　金属压花彩板 　　■冷轧基板彩色涂层钢板 　　由冷轧基板生产的彩色板，具有平滑美丽的外观，且具有冷轧板的加工性能；但是表面涂层的任何细小划伤都会把冷轧基板暴露在空气中，从而使露铁处很快生成红锈。因此这类产品只能用于要求不高的临时隔离措施和作室内用材。 　　■热镀锌彩色涂层钢板 　　把有机涂料涂复在热镀锌钢板上得到的产品即为热镀锌彩涂板。热镀锌彩涂板除具有锌的保护作用外，表面上的有机涂层还起了隔绝保护、防止生锈的作用，使用寿命比热镀锌板更长。热镀锌基板的含锌量一般为180g/m2（双面），建筑外用热 　　镀锌基板的镀锌量最高为275g/m2。 　　■热镀铝锌彩涂板 　　根据要求，也可以采用热镀铝锌钢板作为彩涂基板（55%AI-Zn和5%AI-Zn）。 　　■电镀锌彩涂板 　　用电镀锌板为基板，涂上有机涂料烘烤所得的产品为电镀锌彩涂板，由于电镀锌板的锌层薄，通常含锌量为20/20g/m2，因此该产品不适合使用在室外制作墙、屋顶等。但因具有美丽的外观和优良的加工性能，因此主要可用于家电、音响、钢家具、室内装潢等。 　　■涂料 　　涂料是一种流动状态或粉末状态的有机物，涂敷于底材上能干燥固化形成一层薄膜，均匀地覆盖和良好地附着。其主要性能为防护性（如耐潮湿性、耐水性、耐候性、耐化学性等）和装饰性（具有各种不同的颜色和光泽）。 　　■涂料的组成及其作用 　　各种不同的涂料，都有四个部分组成，即（1）树脂（2）颜料（3）溶剂（4）助剂。其中溶剂是挥发分，其作三个部分基本是不挥发分。 　　（1）树脂 　　树脂即成膜物质，是涂料中的最主要成分和基础，也称基料，它是决定涂膜性质的主要因素。要求作为成膜物质的树脂在 　　涂料储存期内相当稳定，不发生明显的物理变化和化学变化；在成膜时，在规定的条件下，能迅速固化成膜。 　　树脂种类繁多，在卷材涂料中常用的树脂有酸树脂、环氧树脂、聚酯树脂和聚基酯树脂等。不同的树`脂，其物理性能和化学性能、以及耐候性、耐蚀性等是不一样的。 　　（2）颜料 　　颜料须与树脂配合使用，在涂料中的主要作用是使涂膜着色，颜料比例不同会影响涂膜硬度、光泽度以及耐蚀性等。 　　（3）溶剂 　　溶剂是液态涂料的重要组成部分，在涂料烘干过程中是能挥发的成分。一般也用溶剂调节涂料粘度，这种用于调节涂料粘度的溶剂称为稀释剂。溶剂对涂料的制造、贮存、涂敷、漆膜的形成和成膜质量有着很大的影响。 　　（4）助剂 　　助剂是为改善涂料性能而加入的少量添加剂。助剂在涂料中用量极少，作用却显著，如有的能改进涂料和涂膜的性能，有的能改善烘干时间、有的能防止涂膜产生病态等。助剂种类繁多，有催干剂、固化剂、流平剂、消泡剂、消光剂，稳定剂等。 　　几乎绝大部分液态涂料都由上述四个成分中的某些原料组成，其中最主要的是树脂，这是任何涂料都少不了的。可以说树脂（有时加溶剂和助剂）就是透明漆，再加入颜料就可成各种色漆。 　　彩色涂层钢板用涂料一般根据用途分为两大类：即建筑用和家电用。建筑用涂料根据使用环境的不同，在环氧树脂、聚酯树脂、聚氯乙烯塑料溶胶、硅改性聚酯和聚偏氟乙烯中选择。家电用涂料一般彩聚酯树脂。 一、什么叫做彩色涂层钢板 现代的彩色涂层钢板是在连续机组上以冷轧带钢、镀锌钢带(电镀锌和热镀锌)和热镀锌一铝合金钢带等为基板，经过表面预处理(脱脂和化学处理)，用辊涂或覆膜等方法，涂覆上一层或多层有机涂层，经过烘烤和冷却所得到的涂装产品即为涂层钢板。由于涂层可以有各种不同的颜色，因此，又称之为“彩色涂层钢板”。又由于涂层是在钢板成型加工之前进行的，在国外亦称之为“预涂层钢板”或‘卷涂”。 二、彩色涂层钢板是由哪几部分构成的 彩色涂层钢板的构成，大体上可分为基材、镀层、化学转化膜和有机涂层4大部分。 三、彩色涂层钢板的涂料品种有哪几大类 按彩色涂层钢板的涂料形态分类，则有液体涂料、粉末涂料、塑料薄膜三大类。 四、用于生产彩色涂层钢板的基材主要有哪几种 按基板分类的彩色涂层钢板的种类，主要有以下四大类别：(1)冷轧基板彩色涂层钢板。(2)热镀锌彩色涂层钢板。(3)热镀铝锌彩色涂层钢板。(4)电镀锌彩色涂层钢板。 五、在剪切彩色涂层钢板时，应注意哪些问题? 彩色涂层钢板根据用途要进行剪切、弯曲、成型等各种加工。由于钢板表面有锌层和有机涂层，加工时有许多与普通冷轧钢板不同的地方，须特别注意，以防加工时涂膜受损。影响剪切的因素包括：(1)材料的力学性能；(2)刀具的形状及间隙；(3)工具面的摩擦及润滑；(4)加工速度和温度等。在剪切彩色涂层钢板时应特别注意以下事项：(1)应尽量使切断面的毛边短小，以防彩色涂层钢板在剪切堆垛时相互划伤；(2)及时清除剪断时产生的切屑和金属粉，否则会损伤钢板表面，成为擦伤或腐蚀生锈的根源；(3)彩色涂层钢带剪切时，与彩色接触的辊子应为胶辊或其他材料，与彩色钢板接触的台面应铺上橡皮垫并保持清洁，防止彩板涂膜损伤。

我们通常用镀锌量来表示镀锌钢材的镀锌层厚度，一个普遍采用的有效方法，镀锌量的单位为g/m2。镀锌层厚度有多种表示方法，例如镀层总厚度、镀层局部厚度、镀层平均厚度等等。镀锌层厚度（coating thickness），是指钢铁表面上锌和(或)锌合金镀层的总厚度，以km表示。镀锌层局部厚度（local coating thickness），在某一基本测量面按规定次数用磁性法所测得的镀层厚度的算术平均值或用称量法进行一次测量所测得的镀层镀覆量的厚度换算值。镀锌层平均厚度（mean coating thickness ），对某一大件或某一批镀锌件抽样后测得镀层局部厚度的算术平均值。镀锌是指在装有镀件、玻璃球、锌粉、水和促进剂的旋转滚桶内，作为冲击介质的玻璃球随着滚桶转动，与镀件表面发生摩擦和锤击产生机械物理能量，在化学促进剂的作用下，将镀涂的锌粉“冷焊”到镀件表面上，形成光滑、均匀和细致的具有一定厚度的镀层。镀锌层厚度直接决定了镀件的防腐蚀性能。可以选择高于或低于标准的锌镀层厚度。对于表面光滑的3mm以下薄钢板，工业生产中得到较厚的镀层是困难的，另外，与钢材厚度不相称的锌镀层厚度会影响镀层与基材的结合力以及镀层外观质量。过厚的镀层会造成镀层外观粗糙，易剥落，镀件经不起搬运和安装过程中的碰撞。

粉末涂料的厚度的技术。它简述了工作原理和相关行业的测试方法和标准。 一、概述 膜厚度测量应该是所有粉末涂布人员（图1）的常规工作。定期测量有助于控制材料成本，管理涂布的效率，并保持表面质量。粉末涂料制造商建议可使涂层达到较佳性能特点的目标薄膜厚度范围并且这些参数满足客户期望。 粉末膜厚固化前和固化后的膜厚可以利用几种不同的仪器进行测量。例如见图2.每个粉末涂覆操作应该知道什么设备是可用的，以及如何使用它。 二、测量膜厚的必要性 薄膜厚度可以说是在保护涂层的应用和检查过程中的一个较重要的测量。粉末涂层专用于由制造商指定的厚度范围进行涂覆实现其预期的功能。许多成品涂层的物体和外观性能会直接受到干膜厚度（DFT）的影响。DFT会影响涂层的颜色、光泽、表面轮廓、附着力、柔韧性、耐冲击性和硬度。如果膜厚不在容差范围内，涂布后的组装件的安装也会受其影响。 准确测量涂层厚度也有其他的好处。是否能满足国际标准化组织（ISO）、产品质量或客户的要求进行过程控制，企业需要确认涂层质量避免为返工产品花冤枉钱。通过检查他们的应用设备，他们保证应用的涂层符合制造商的建议。 施涂者必须均匀地涂覆粉末涂料，并且要根据产品规格表的要求。施涂过大的DFT不仅浪费，而且会有不完全固化的可能的风险，并且会大大减少涂层系统的整体性能。高膜构造通常会导致粘结强度低。涂层容易从基材上剥离或破裂。定期检测可以减少内部返工和因加工缺陷而客户退货的数量。 三、符合标准 粉末涂层厚度的测量要根据测试是在粉末固化之前或之后来使用不同的测量方法。美国社会测试和材料协会（ASTM）具有一系列的描述这些技术的标准。 D 4138测试方法描述了用切片仪器测试坚固底材的破坏性测量方法。 D 7091操作规程描述了用磁性测厚仪和 涡流测厚仪测量金属底材的非破坏性测量方法。D6132测试方法描述了用超声波测厚仪 测量非金属底材的非破坏性测量方法。 D 7378标准描述了三种测量制备的预固化粉末涂层的厚度的方法来预估固化后的厚度。 四、膜厚度测量的概要 膜厚测量可以在固化和交联之前或之后进行。基底的类型、涂层的厚度范围、涂层的大小和形状及作业的经济能力决定使用的测量方法。 在未固化的粉末涂料，高度的测量可以用粉梳子和使用专用的粉末探头的电子测量仪进行测量。由于在固化过程粉末涂层的厚度会减少，所以要确定减少的因素来预测固化后的DFT。另外，超声波仪器测量未固化的粉末不用接触表面并且能自动预测粉末的固化厚度。 固化后，各种手持设备可在涂层部分上进行直接DFT测量。这些非破坏性的测厚仪器要根据底材的类型来选择是磁感应、还是电涡流或者是超声波原理。不太常见的方法包括微米测量，破坏性干膜方法如横切片，和重量（质量）的测量。 1、标准测量单位 在美国粉厚度测量中使用的正常标准单位是密耳;1.0密耳等于千分之一英寸（1/1000英寸）。如果制造商的指定厚度为2.0到5.0密耳，该粉末的较终固化厚度应为0.002英寸和0.005英寸之间。测量的公制单位被称为微米（微米）;25.4微米等于1.0密耳。 涂布器必须要均匀地施涂粉末涂料，并且要根据产品规格表。这提供了特定粉末规范的较大利益。大多数厚度检测规范适用于粉末的固化厚度，所以我们看到不同厚度的测量技术开始出现。 2、固化膜厚度测量 千分尺是用于检测DFT的原始仪器之一，并且仍然在今天被应用。它具有测量任何涂层/底材组合的优点，但是存在要求同时测量裸露基材厚度的缺点。必须进行两次测量：一次包含涂层，而另一次没有。两个读数，高度变化之间的差，是涂层厚度。 有两种破坏性的技术也可使用。一个是通过显微镜观察切割切断的截面中的包覆部分并测量膜厚度。另一种是通过固化的涂层使用缩放显微镜查看一个几何切口。当不能使用廉价的，无损的方法，或者当非破坏性结果需要确认时需要使用这方法。 较普遍的测量固化粉末厚度的方法就是使用电子DFT测量仪。它们是手持式、易于操作，并且成本相对较低。它们根据材料的类型选择磁感应、电涡流或超声波原理。 当零件是由钢制成的可使用机械计。其采用较久磁铁和一个校准弹簧。该装置测量将磁铁从涂覆钢表面拉出所需的力。磁拉断计是坚固耐用，操作简单，价格低廉，携带方便，并且通常不需要任何校准调整。它们在一些只需几个读数的生产场合是比较合适且经济的替代方法。 由于具有简单性、多功能性、准确性和具有保持记录功能的原因，电子DFT测量仪器对于大型和小型粉末操作都是非常热门的选择。他们使用磁感应原理测量钢底材，使用电涡流原理测量其他金属底材。有时会集两种原理于一台仪器中。测试的结果直接显示在易于读取的液晶显示屏（LCD）上。多种探头可选择用于测量不规则形状或准确测量非常薄或非常厚的涂层系统。 非金属底材测量如涂覆的塑料或木材要求使用超声波脉冲技术。这为之前行业无法以合理价格进行非破坏性质量控制提供一个可能。这种测量技术的一个好处是在一个多层涂层系统测量所述各个层的可能性。 3、预固化膜厚度测量。 到目前为止讨论的测量方法已经使用在部分固化后的粉末厚度。它也可以，甚至在某些情况下更可取的，在制备后立即测量涂层以预测固化后的粉末涂层的厚度。 如果涂层被不正当地施涂后，校正已经干燥或化学固化需要昂贵的额外的劳动时间，可能会导致膜的污染，并可能引入粘合性和涂层系统的完整性的问题。制备过程中测量膜厚度可确定涂布器是否需要立即校正或调节。 4、干粉末的测量。 虽然大多数粉末涂料规格规定了固化的目标厚度，这可以在较终固化和交联之前确定施涂的粉末是否符合厚度规格。 有很好的理由需要一个准确的固化DFT预测值，尤其是在移动线。取决于烘箱的长度，被固化的部分数量，以及固化过程所需的时间和固化后手动测量DFT值的时间，在操作者为做一些必要的修改而在应用过程中进行干预之前有一个相当充分的延迟时间。 如果发现涂层缺陷，相当大的涂覆部分不得不在一个修配环中重新加工，或者如果重新加工的成本太高，它们甚至可能不得不废弃。对于某些操作，对于满足现代加工程序的要求这些缺点是无法接受的。 在预固化、预凝胶状态时测量粉末确保正确的固化膜厚度。这样能够在固化前对应用系统进行设置和微调。反过来，这将减少废料的数量和过度喷雾情况。准确的预测能够避免剥离和再涂层，不然可能会导致附着力和涂层完整性问题。 ASTM D 7378标准描述了测量涂覆粉末涂层的三个程序： A.硬金属缺口（梳）计 B.带专用粉末探头的电子涂层测量仪器 C.非接触式超声波仪器 金属缺口计。这仪器通过手拖过涂覆的粉末手动地测量厚度。与湿膜测厚仪的工作原理类似，仪器确定的粉末高度值是在做有一个记号的、并且有粉末粘附在上面的较高编号的齿和没有留记号的、没有粉末粘附在上面的第二高的齿之间的高度。这些简单的工具便宜，但只能准确到几密尔。测量能够在一个合适的刚性底材进行，但记号将会在当粉末在固化过程中流动时没有被覆盖的粉末中标记。 电子测量仪。使用专用的粉末探头仪器能够测量涂覆的粉末厚度。内置在探头的微针穿透粉末涂层到底材上。然后将探头手动压在粉末层的表面实现厚度测量。这种方法仅适用于平坦的金属底材并且可能会在较终产品留下痕迹。 上述两种方法仅用于未固化的粉末涂层的高度测量。但如前所述，大部分厚度说明经常是指已固化的粉末厚度。由于粉末涂料通常在固化过程中在厚度减少高达50％，这两个步骤需要为每个特定的涂层粉末建立缩减因子来预测的固化膜厚度。减少因子的确定是通过在已经测量的未固化粉末高度的同一位置测量固化粉末涂层的厚度，然后测量前后两者相减获得。 非接触式超声波仪表。ASTM D 7378的方法C描述了一种相对新型的仪器，这种仪器已迅速成为干粉厚度测量一个流行的解决方案。它是一个超声波仪器能够非破坏性在未固化的粉末上测量来预测较终的DFT值，并且不会留下任何影响成品的痕迹。 这些仪器是手持式和电池供电的，对于大多数粉末是开箱即可用。他们的操作简单和电子设计的特点使得其能够被线路操作者快速且有效地使用。 非接触是涂层厚度测量仪具有无损的决定性优势。这意味着，测量之后，测量的组件可以重新引入到正在进行的进程中。 五、膜厚度测量的准确度 这些仪器都是操作简单的，一个谨慎的用户应该定期验证他们的操作，尤其是当符合国际ISO标准规定程序。这三个步骤确保较佳的精度值。 1、校准 涂层测厚仪的校准通常是有设备制造商在受控环境中进行的一个文件化过程。校准证书显示可朔源到一个国家计量机构就可被发布。重新校准没有标准的时间间隔，也不是一个的要求，但可以在经验和工作环境的基础上建立一个标准的时间间隔。为期1年的校准间隔是许多仪器制造商提出了一个典型的频率。 2、验证 这是一个用户与已知的参考标准进行的准确检查。这个快速的检查能够确保仪器正常测量和用户正确操作它。对于许多测量仪，精度可以通过测量带有可追溯到国家计量机构的分配值的塑料垫片或环氧树脂涂层标准进行验证。 3、调整 调整，或校准调整，是校对测量仪的厚度读数以匹配已知的参考样品，为提高测量仪在其测量范围的特定部分内的一个特定的涂层的准确度的行为。此操作在粉末涂料工业很少需要的，因为在粉末涂层材料中的声学特性变化不大。 六、涂层质量控制 在当今竞争激烈的环境中，客户往往会选择具有坚实的质量控制系统的加工公司。通过在一个有记录和分析DFT结果的简单系统投资，粉末涂布者可以研究趋势，减少成本，并提供客户体现他们能够满足要求的参数的实力资料来留住客户。 一个质量保证（QA）程序是指开发一个简单的程序，要求在每一部分的相同位置进行一定数量的厚度测量。通过记录所有的数值，然后定期进行变化分析，并且采取必要的纠正措施。 通过笔和纸手动收集数据不仅耗时且容易出错，而且会对涂料项目增加显著成本。具有测量结果存储功能的测厚仪消除了这种风险。自动化采集读数的功能是保持成本在控制范围，减少人为错误的较好方法。在数字格式，数据可容易地存储，报告，和输出。

电镀锌钢板，是指采用电镀锌工艺镀锌的钢板。与热镀锌钢板相比，镀锌层厚度薄，但成本低。电镀锌也叫冷镀锌，就是利用电解原理，在制件表面形成均匀、致密、结合良好的锌镀层的过程。与其他 金属 相比，锌是相对便宜而又易镀覆的一种 金属 ，属低值防蚀电镀层，被广泛用于保护钢铁件，特别是防止空气氧化腐蚀，并用于装饰。镀锌板是指表面镀有一层锌的钢板。镀锌是一种经常采用的经济而有效的防腐方法。全世界锌 产量 的一半左右均用于此种工艺。镀锌是为防止钢板表面遭受腐蚀延长其使用寿命。镀锌板 市场 概况及生产消费现状近几年，我国镀锌板的生 产量 在逐年增加，出进口量也在逐年增加，增长幅度高于生 产量 的增加；扣除生产重复统计后，镀锌板消费量约为527万吨。1999年以后，进口量超过了生 产量 ，国内产品的自给率不足50％，并且有逐年降低的趋势。镀锌板消费量的增加主要依靠进口。近几年镀锌板进口逐年增长、进口的品种主要是电镀锌板，但电镀锌板进口的比例逐年降低；相应地，热镀锌板进口比例逐年增加，2003年我国热镀锌板的进口量第一次超过了电镀锌板的进口量。电镀锌钢板的特点：用电镀法制造这种镀锌钢板具有良好的加工性，但镀层较薄，耐腐蚀性不如热浸法镀锌板。

钢板镀锌是提高钢板耐锈蚀性能、装饰美观的一种工艺手法。目前，最常用的钢板镀锌方法是热镀锌。镀锌钢板是为防止钢板表面遭受腐蚀，延长其使用寿命，在钢板表面涂以一层 金属 锌，这种涂锌的钢板称为镀锌板或镀锌钢板。镀锌钢板广泛用于建筑、轻工、汽车、家电、电子、农牧渔业、商品包装等 行业 。近几年，我国建筑、家电等 行业 对镀锌板需求增长很快， 市场 潜力较大，尤其是近年来随着建筑轻型结构的迅速发展，轿车 产量 的逐年增加，家用电器的广泛普及，合资、独资企业电子产品的大量出口，使镀锌板的消费量增长较快。按生产方式分，镀锌板分为热镀锌板和电镀锌板。目前，国内镀锌板的生产无论是数量还是品种均不能满足 市场 需求，每年需要大量进口，国内镀锌板生产 市场 占有率较低，国内 市场 供不应求， 市场 潜力巨大。热镀锌钢板，将薄钢板浸入熔解的锌槽中，使其表面粘附一层锌的薄钢板。目前主要采用连续镀锌工艺生产，即把成卷的钢板连续浸在熔解有锌的镀槽中制成镀锌钢板；电镀锌钢板，用电镀锌法制造这种镀锌钢板具有良好的加工性。但镀层较薄，耐腐蚀性不如热浸法镀锌板；单面镀和双面差镀锌板，单面镀锌钢板，即只在一面镀锌的产品。在焊接、涂装、防锈处理、加工等方面，具有比双面镀锌板更好的适应性。为克服单面未涂锌的缺点，又有一种在另面涂以薄层锌的镀锌板，即双面差镀锌板；合金化镀锌板，这种钢板也是用热浸镀锌法制造，但在出槽后，立即把它加热到500℃左右，使其生成锌和铁的合金被膜。这种镀锌板具有良好的涂料的密着性和焊接性；合金、复合镀锌板，它是用锌和其他 金属 如铅、锌制成合金乃至复合镀成的钢板。这种钢板既具有卓越的防锈性能，又有良好的涂装性能。国内镀锌钢板生产消费存在的主要问题：生产品种不全；缺少锌合金镀层板；生产规格单一；生 产量 不足，机组能力小。钢板镀锌能有效地延长钢板的腐蚀时间，使得钢板的利用价值得到提升，目前钢材 市场 的镀锌钢板的 价格 也在小幅度的上涨。

这是近年发展起来的新型吊顶材料，不仅能防火防潮，还能防腐抗静电、吸音隔音，美观实用，可算是较好的吊顶材料。铝花板分网格天花、方形扣板、条形扣板等。表面可分为冲孔和平面两种。表面冲孔可组成多种图案。冲孔的较大作用是通气和吸音，扣板内部铺有一层薄膜软垫，潮气可透过冲孔被薄膜吸收。这种通风透气性较适合厨房和卫生同等水分较多的地方使用。铝花板表面经过涂料加热固化处理，有丝光、丝面，镜面等不同光泽效果和各种色彩系列，如蓝天白云的图案装饰效果就十分明显。国产铝花板的基本材料为铝镁合金、铝锰合金，进口产品的基本材料为铝锌合金，硬度高于国产。检验铝花板的质量主要看表面网眼的形状，大小要均匀，排列要整齐，表面喷塑后光泽度好，厚度要均匀。现在市面上比较好的铝扣板有爱力浦集成吊顶铝扣板，质量保证加上技术创新，其生产的滚涂板、腹膜板、印刷板、阳极氧化板等在延续了传统的铝扣板的基础上，融入新的技术创新，将集成吊顶中的铝扣板产品推到一个新的高度。 （摘自中国建材网）

钢板是钢材四大品种（板、管、型、丝）之一，在发达国家，钢板产量占钢材生产总量50%以上，随着我国国民经济的发展，钢板生产量逐渐增长。    钢板是一种宽厚比和表面积都很大的扁平钢材。钢板按厚度分为薄板和厚板两大规格。    薄钢板是用热轧或冷轧方法生产的厚度在0.2-4mm之间的钢板。薄钢板宽度在500-1400mm之间。根据不同的用途，薄钢板采用不同材质钢坯轧制而成。通常采用材质有普碳钢、优碳钢、合金结构钢、碳素工具钢、不锈钢、弹簧钢和电工用硅钢等。它们主要用于汽车工业、航空工业、搪瓷工业、电气工业、机械工业等部门。薄钢板除轧制后直接交货之外，还有经过酸洗的、镀锌和镀锡等种类。    厚钢板是厚度在4mm以上的钢板的统称，在实际工作中，常将厚度小于20mm的钢板称为中板，厚度＞20mm至60mm的钢板称为厚板，厚度＞60mm的钢板则需在专门的特厚板轧机上轧制，故称特厚板。厚钢板的宽度从0.6mm-3.0mm。厚板按用途又分造船钢板、桥梁钢板、锅炉钢板、高压容器钢板、花纹钢板、汽车钢板、装甲钢板和复合钢板等。    钢板的一个分支是钢带，钢带实际上是很长的薄板，宽度比较小，常成卷供应，也称为带钢。钢带常在多机架连续式轧机上生产，切成定尺长度后就是钢带，因此生产率比单张机制时高。    一、中厚板    （一）普通中厚钢板    1、普碳钢沸腾钢板（GB3274-88）    普碳钢沸腾钢板顾名思义是由普通碳素结构钢的沸腾钢热轧制成的钢板。沸腾钢是一种脱氧不完全的钢材，钢液含氧量较高，当钢水注入钢锭模后，碳氧反应产生大量气体，造成钢液呈沸腾状态而得名。沸腾钢含碳量低，且由于不用硅铁脱氧，故钢中含硅量常＜0.07%。沸腾钢的外层是在沸腾状态下结晶的，所以表层纯净、致密，表面质量好，加工性能良好。沸腾钢没有大的集中缩孔，用脱氧剂少，钢材成本低。沸腾钢心部杂质多，偏析较严重，力学性能不均匀，钢中气体含量较多，韧性低、冷脆和时效敏感性较大，焊接性能较差，故不适用于制造承受冲击截荷，在低温下工作的焊接结构件和其他重要结构件。    沸腾钢板大量用制造各种冲压件、建筑及工程结构和一些不太重要的机器结构和零件。其材质的牌号、化学成分和力学性能符合GB700-79（88）（普通碳素结构钢技术条件）中沸腾钢的规定。热轧中厚钢板厚度为4.5-200mm。生产单位主要有鞍钢、武钢、马钢、太钢、重庆钢厂、邯郸钢铁总厂、新余钢厂、柳州钢厂、安阳钢钢公司、营口中板厂和天津钢厂等。    2、普碳钢镇静钢板（GB3274-88）    普碳镇静钢钢板是由普通碳素结构钢镇静钢坯热轧制成的钢板。镇静钢是脱氧完全的钢，钢液在注锭前用锰铁、硅铁和铝等进行充分脱氧，钢液在钢锭模中较平静，不产生沸腾状态，故得名为镇静钢。镇静钢的优点是化学成分均匀，所以各部分的机械性能也均匀，焊接性能和塑性良好、抗腐蚀性较强。但表面质量较差，有集中缩孔，成本也较高。    普通镇静钢板主要用于生产在低温下承受冲击的构件、焊接结构及其他要求较高强度的结构件。其材质的牌号、化学成分和力学性能符合GB700-79（88）（普通碳素结构钢技术条件）中镇静钢的规定。钢板的规格尺寸厚度4.5-200mm。生产单位主要有鞍钢、武钢、舞阳钢铁公司、马钢、太钢、重庆钢厂、邯郸钢铁总厂、新余钢厂、柳州钢厂、安阳钢铁公司、天津钢厂、营口中板厂、上钢一、三厂、韶关钢铁厂和济南钢铁厂等。    3、低合金结构钢板（GB3274-88）    低合金结构钢板是由低合金结构钢热轧制成的。低合金钢板都是镇静钢和半镇静钢板。其优点是强度较高、性能较好、能节省大量钢材、减轻结构重量等。低合金结构钢板越来越广泛用于机械制造和金属结构件等。热轧钢板厚度为4.5-200mm。生产单位包括鞍钢、武钢、舞阳钢铁公司、马钢、重庆钢厂、新余钢厂、柳州钢厂、昆明钢铁公司、天津钢厂、韶关特钢厂、安阳钢铁公司、上钢一、三厂和太钢等。    4、一般结构用热连轧钢板（GB2517-81）    主要用于建筑、桥梁、车辆等一般结构。钢板（带）厚度从1.2-13.0mm；宽度从700-1550mm；长度从2000-12000mm。    5、焊接结构用耐候钢板（GB4172-84）    耐候钢即耐大气腐蚀钢。焊接结构用耐候钢是在钢中加入少量的合金元素，如钢、铬、镍、钼、铌、钛、锆和钒等，使其在金属基体表面形成保护层，以提高钢材的耐候性，以及良好的焊接性能。主要用于桥梁、建筑及其他结构。    6、高耐候性结构钢钢板（GB4171-84）    耐候钢即耐大气腐蚀济。在钢中加入少量合金元素，如钢、磷、铬、镍、钼铌、钛、锆和钒等，使在金属基体表面形成保护层面提高钢材的耐候性能。主要适用于建筑、车辆、塔架和其他结构件。    7、花纹钢板（GB3277-82）    花纹钢板是其表面具有菱形或扁豆形突棱的钢板。其规格以其本身厚度（突棱的厚度不计）表示。花纹板具有防滑作用，常用作地板、厂房扶梯、工作架踏板、船舶甲板和汽车底板等。花纹板的材质用普通碳素结构钢的B1、B2和B3牌号钢轧制而成，其化学成分符合GB700-79（普通碳素结构钢技术条件）的规定。生产单位主要有鞍钢和安阳钢铁公司等。    8、桥梁用钢板（YB168-70）    桥梁钢板是专用于架造铁路或公路桥梁的钢板。要求有较高的强度、韧性以及承受机车车辆的载荷和冲击，且要有良好的抗疲劳性、一定的低温韧性和耐大气腐蚀性。拴焊桥梁用钢还应具有良好的焊接性能和低的缺口敏感性。主要用于铁路桥和公路桥其跨度在46-160mm之间的结构件。其规格：厚度从6-50mm、宽度从1.0-2.4mm、长度从2.0-16mm。我国生产桥梁用钢板主要有鞍钢、武钢、上钢三厂和重庆钢厂等单位。    9、船体结构用钢板（GB712-88）    船体结构用钢板简称船用板。由于船舶工作环境恶劣，船体壳要受海水的化学腐蚀、电化学腐蚀和海生物、微生物的腐蚀；船体承受较大的风浪冲击和交变负荷；船舶形状使其加工方法复杂等因素、所以对船体结构用钢要求严格。首先良好的韧性是最关键的要求，此外，要求有较高的强度，良好的耐腐蚀性能、焊接性能，加工成型性能以及表面质量。为保质量和保证有足够的韧性，要求化学成分的Mn/C在2.5以上，对碳当量也有严格要求，并由船检部门认可的钢厂生产。船体用结构钢分一般厚度和高强度钢两种，一般强度钢按质量分A、B、C和D四个等级；高强度钢又分两个强度级别和三个质量等级；AH32、DH32、EH32、AH36、DH36、EH36。    船体结构用钢板主要用于制造远洋、沿海和内河航运船舶的船体、甲板等的钢板。产品规格：厚度4.5-50mm、宽度1.0-2.2mm、长度4.0-12.0m。我国主要由武钢、马钢、上钢一、三厂、太钢、昆明钢铁公司和天津钢厂等生产。    10、锅炉用钢板（GB713-86）    按用途分，锅炉分工业锅炉和电站锅炉用两大类。工业锅炉通常是工业企业用于供热，属小型锅炉，其所用钢材为普通碳素结构钢和低合金结构钢。电站锅炉属大、中型锅炉，对钢材质量有特殊要求，一般要求具有优良综合性能的合金钢来制造。主要用于制作固定锅炉、船体锅炉及其他锅炉重要附件。钢板厚度从6-120mm。生产单位主要有鞍钢、武钢、上钢三厂、舞阳钢铁公司、柳州钢厂、重庆钢厂、太钢、昆明钢铁公司等生产。

65锰钢板价格,国内65锰钢板仍弱势盘整，市场成交较为冷清，钢厂公布采购价格低且量少，65锰钢板生产厂家信心差，亏损严重，较多地区小企业停炉、大厂选择减产，出口市场仍冷清，国际硅锰价格低于国内报价。国内65锰钢板FeMn65Si17市场出厂综合报价在6700-7100元/吨，FeMn60Si14市场报价在5400-6000元/吨，出口FOB报价在1030-1200美元。国内65锰钢板走势仍无起色，各地硅锰厂家亏损严重，钢厂采购价格低且采量少，虽目前各家报价暂无跌幅，但均表示，由于较多钢厂定价低，市场实际成交价格又有所小幅下调，较多厂家成本高，只能关停炉子，暂时不对外销售，以应对当前弱势。从矿石方面来看，同样受制于成交冷清，价格继续处于弱势，但由于国外矿石报价高，进口锰矿价格暂无太大跌幅，港口贸易商也不敢操作，对于短期内市场，各方均认为，由于整个钢铁体系的走弱，65锰钢板价格较难出现回暖可能，但市场大批硅锰企业关停，现货资源紧张致使个别地区价格小幅上调也不无可能。国内主要市场65锰钢板出厂价格继续持稳，市场成交略有转好。今日湖南地区的主流成交价维持在12300元/吨，部分厂家有12200元/吨的价格出货。目前市场上除重庆秀山地区有厂家陆续复工意以外其他地区产量基本稳定，下游需求近期也无太大的变动，这也是近期65锰钢板价格一直稳定的原因，厂家对后市也是比较茫然。有消息称民营钢厂本月第一次碰头会将于近日进行，本月的产量将成为主要探讨议题，之前外界一直预计本月民营钢厂将会继续减产。65锰钢板出口价格仍在2300美元/左右，尽管市场上询盘有所增加，但采购依然低迷。不过现在不锈钢行业已经开始出现回暖迹象，65锰钢板做为上游原料也会受到影响，不过有一定的滞后性。预计近期65锰钢板价格仍将平稳运行，长期或许有小幅上涨的可能。

镀锌板是为防止钢板表面遭受腐蚀，延长其使用寿命，在钢板表面涂以一层 金属 锌，这种涂锌的钢板称为镀锌板或镀锌钢板。镀锌板广泛用于建筑、轻工、汽车、家电、电子、农牧渔业、商品包装等 行业 。近几年，我国建筑、家电等 行业 对镀锌板需求增长很快， 市场 潜力较大，尤其是近年来随着建筑轻型结构的迅速发展，轿车 产量 的逐年增加，家用电器的广泛普及，合资、独资企业电子产品的大量出口，使镀锌板的消费量增长较快。按生产方式分，镀锌板分为热镀锌板和电镀锌板。目前，国内镀锌板的生产无论是数量还是品种均不能满足 市场 需求，每年需要大量进口，国内镀锌板生产 市场 占有率较低，国内 市场 供不应求， 市场 潜力巨大。镀锌板按生产及加工方法可分为以下几类：①热浸镀锌板将薄钢板浸入熔解的锌槽中，使其表面粘附一层锌的薄钢板。目前主要采用连续镀锌工艺生产，即把成卷的钢板连续浸在熔解有锌的镀槽中制成镀锌钢板；②合金化镀锌板这种钢板也是用热浸镀锌法制造，但在出槽后，立即把它加热到500℃左右，使其生成锌和铁的合金被膜。这种镀锌板具有良好的涂料的密着性和焊接性；③电镀锌板用电镀锌法制造这种镀锌钢板具有良好的加工性。但镀层较薄，耐腐蚀性不如热浸法镀锌板；④单面镀和双面差镀锌板单面镀锌钢板，即只在一面镀锌的产品。在焊接、涂装、防锈处理、加工等方面，具有比双面镀锌板更好的适应性。为克服单面未涂锌的缺点，又有一种在另面涂以薄层锌的镀锌板，即双面差镀锌板；⑤合金、复合镀锌板它是用锌和其他 金属 如铅、锌制成合金乃至复合镀成的钢板。这种钢板既具有卓越的防锈性能，又有良好的涂装性能。镀锌板的外观（1）表面状态：镀锌板由于涂镀工艺中处理方式不同，表面状态也不同，如普通锌花、细锌花、平整锌花、无锌花以及磷化处理的表面等。（2）镀锌板应具有良好的外观，不得有对产品使用有害的缺陷，如无镀、孔洞、破裂以及浮渣、超过镀厚、擦伤、铬酸污垢、白锈等。国外标准对具体外观缺陷规定都不十分明确。国内镀锌板生产消费存在的主要问题1、生 产量 不足，机组能力小2、生产品种、规格、质量有待提高①生产品种不全②生产规格单一③缺少锌合金镀层板④热镀锌板原料自给率低总之，高质量、高档次的热镀锌板，尤其是汽车、家电用镀锌板，要求具有非常高的表面质量、优良的板型、不同的合金化镀层、深冲性能良好、强度高。因此，生产高质量热镀锌板生产是一个系统工程，对冶炼、连铸、热轧、冷轧、镀锌等一系列生产工序均提出质量一贯制的要求，生产难度较大。 

电工钢板（又称硅钢片、矽钢片）是指一种含碳量极低（经退火后，含碳量在0.005％以下）的硅铁软磁合金，一般硅含量为0.5％～4.5％，铁中加入硅可以提高其电阻率和最大导磁率。主要用来制造各种变压器、电动机和发电机的铁芯。电工钢板分为两大类，即取向电工钢板和无取向电工钢板。 开发电工钢板一种具有高导电性能和高耐蚀性的无铬钢板 ,据说这种无铬耐蚀的高导电性钢板是在其表面上涂复了一层很薄的无铬涂层 ,这种涂层既能提供耐蚀性又提高了其导电性。日本钢公司开发的一种新型电工钢板

冷轧钢板就是经过冷轧生产的钢板，俗称冷板。　　冷轧是在室温条件下将No.1钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较，冷轧钢板厚度更加精确，而且表面光滑、漂亮，同时还具有各种优越的机械性能，特别是加工性能方面。因为冷轧原卷比较脆硬，不太适合加工，所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下，如大部份工厂冷轧钢板厚度是4.5MM以下；最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。 　　一般来说，冷轧钢板分为三代产品：沸腾钢为第一代，铝镇静钢为第二代，无间隙原子刚（IF钢）为第三代。   您查询的关键词是：冷轧钢板  。如果打开速度慢，可以尝试快速版；如果想保存快照，可以添加到搜藏。 "冷轧钢板""2,冷轧钢板(YB459-64)""厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)",,"厚度(mm)","宽度和长度 (mm)","理论重量(kg/m2)(比重:8.9)""0.4","600x1200 700x1430 800x1500 1000x2000","3.56",,"2.5","6000x1200 7000x1430 800x1500 1000x2000","22.25""0.45",,"4.01",,"2.75",,"24.48""0.5",,"4.45",,"3.0",,"26.70""0.6",,"5.34",,"3.5",,"31.50""0.7",,"6.23",,"4.0",,"35.60""0.8",,"7.12",,"4.5",,"40.05""0.9",,"8.01",,"5.0",,"44.50""1.0",,"8.90",,"5.5",,"48.95""1.1",,"9.79",,"6.0",,"53.40""1.2",,"10.68",,"6.5",,"57.85""1.35",,"12.02",,"7.0",,"62.30""1.5",,"13.35",,"7.5",,"66.75""1.65",,"14.60",,"8.0",,"71.20""1.8",,"16.02",,"9.0",,"80.10""2.0",,"17.80",,"10.0",,"89.00""2.25",,"20.03""冷轧铜条""2,冷轧铜条(YB459-64)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.9)""0.20","200~400","500~800","1.78",,"2.50","200~500","500~2000","22.25""0.25",,,"2.23",,"2.75",,,"24.48""0.30",,,"2.67",,"3.00",,"1000~2000","26.70""0.35",,,"3.12",,"3.50",,,"31.15""0.40","200~500","500~2000","3.56",,"4.00",,,"35.60""0.45",,,"4.01",,"4.50",,,"40.05""0.50",,,"4.45",,"5.00",,,"44.50""0.60",,,"5.34",,"5.50",,,"48.95""0.70",,,"6.23",,"6.00",,,"53.40""0.80",,,"7.12",,"6.50",,,"57.85""0.90",,,"8.01",,"7.00",,,"62.30""1.00",,,"8.90",,"8.00",,,"71.20""1.20",,,"10.68",,"9.00",,,"80.10""1.30",,,"11.57",,"10.00",,,"89.00""1.40",,,"12.46",,"11.00",,,"97.90""1.50",,,"13.35",,"12.00",,,"106.8""1.60",,,"14.69",,"13.00",,,"115.7""1.80",,,"16.02",,"14.00",,,"124.6""2.00",,,"17.80",,"15.00",,,"133.5""注 铜板和条(热轧,冷轧)的制造牌号为T2,T3,T4和TU和TUP,其化学成分应符合YB145-71规定""特殊用冷轧黄铜条""3,特殊用冷轧黄铜条(YB555-65)""厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)",,"厚 度 (mm)","宽度 (mm)","长度 (mm)","理论重量(kg/m2) (比重:8.8)""0.20","200~300","500~1000","1.76",,"1.6","200~500","500~2000","14.08""0.25",,,"2.20",,"1.8",,,"15.84""0.30","200~400",,"2.64",,"2.0",,,"17.60""0.35",,,"3.08",,"2.5",,,"22.00""0.40","200~500",,"3.52",,"2.75",,,"24.20""0.45",,,"3.96",,"3.0",,,"26.40""0.50",,"500~2000","4.40",,"3.5",,,"30.80""0.55",,,"4.84",,"4.0",,,"35.20""0.60",,,"5.28",,"4.5",,,"39.60""0.70",,,"6.16",,"5.0",,,"44.00""0.80",,,"7.04",,"5.5",,,"48.40""0.90",,,"7.92",,"6.0",,,"52.80""1.0",,,"8.8",,"6.5",,,"57.20""1.2",,,"10.56",,"7.0",,,"61.60""1.3",,,"11.44",,"8.0",,,"70.40""1.4",,,"12.32",,"9.0",,,"79.20""1.5",,,"13.20",,"10.0",,,"88.00""注 (1)标记举例:用H80制成的,厚度为0.8mm,宽度为300mm,长度为1000mm的1/2硬条标记为:"" 条H80-Y20.8x300x1000YB555-65.""
