镀锌板为防止钢板表面遭受腐蚀延长其使用寿命

  

       镀锌板是为防止钢板表面遭受腐蚀延长其使用寿命,在表面镀有一层锌的钢板。镀锌是一种经常采用的经济而实用的防腐方法,正常锌产量的一半左右均用于此种工艺。

       Galvanized sheet is to prevent corrosion of steel plate surface, prolong its service life, the surface is coated with a layer of zinc steel plate。

无花镀锌板

      无花镀锌板是在锌液中添加了锌花促进元素,同时将锌液中的铅含量减少到几十个PPM以后,锌层在凝固的时候形成不明显的锌花,表面光洁平整。      The zinc free galvanized sheet is added with zinc flowers to promote the elements in the zinc liquid。When the zinc layer is solidified。 the zinc flower is not obvious and the surface is smoothe and smooth。      

有花镀锌板

       有花镀锌板是正常镀锌后冷凝成型的,它又分为:大花镀锌板和小花镀锌板。大花镀锌板,晶粒粗大,还存在细微的凹凸。小花镀锌板是在冷却的时候采用了各种方法来抑制锌花大小。小锌花因为表面比较光滑,所以涂装性能更好。      The galvanized galvanized sheet is formed by condensation after normal galvanizing。 It is divided into big flower galvanized sheet and small galvanized sheet。

深冲镀锌板

  深冲镀锌板,也叫拉伸镀锌板,是具备一定拉伸性能的镀锌板。抗拉强度、屈服强度、延伸率等性能适合冲压使用。国内一般以牌号区分普通镀锌板和拉伸镀锌板。       Deep drawing galvanized sheet, also called tensile galvanized sheet, is a galvanized sheet with certain tensile properties. Tensile strength, yield strength, elongation and other properties are suitable for stamping. In China, ordinary galvanized sheet and galvanized galvanized sheet are generally distinguished by brand.

高锌层镀锌板

     高锌层镀锌板是指锌含量比普通镀锌板更高,防腐性能更好,技术要求更高,板面更平滑光整的镀锌板。国内一般镀锌板的锌层含量是双面80g/㎡。而高锌层镀锌板则能达到120g/㎡、180g/㎡、275g/㎡。         High zinc coating galvanized sheet refers to the zinc content is higher than the ordinary galvanized sheet, better corrosion protection, higher technical requirements, more smooth surface, galvanized galvanized sheet.
