镀锌有几种方法，分别有什么特点？镀锌有几种方法,分别有什么特点和作用-森宝五金网

　　镀锌工艺非常多，常见和常用的一般是热镀锌和电镀锌

　　热镀锌主要应用在工业品中，热镀锌层一般在35μm以上，标准要求在80μm左右，有些甚至高达200μm，覆盖能力好，镀层致密，在长年累月的岁月中，就算受到氧化破坏，也会不断在表明生成保护膜，不断保护内里，主要用在各种线路配件金具或重要的持久性工业产品中。电镀层比热浸层均匀，一般都较薄，从几个微米到几十微米不等。通过电镀，可以在机械制品上获得装饰保护性和各种功能性的表面层，还可以修复磨损和加工失误的工件，电镀锌层较薄，主要为了增强金属的抗腐蚀性(镀层金属多采用耐腐蚀的金属)、增加硬度、防止磨耗、提高导电性、光滑性、耐热性和表面美观。主要应用在各种装饰品或奢侈品中器械。

　　工业中对热镀锌需求量较高，尤其是各种施工工程中需要用热镀锌件。而电镀一般用在日常消费品中，比如手表、汽车外膜等等，所以如果有镀锌方面的需求可以根据自己的需要来进行选择。
