福州热镀锌的防护性能与镀锌层形成原理

发布日期:2017-08-21 作者:福州热镀锌 点击:

      福州热镀锌也叫热浸锌和热浸镀锌:是一种有效的金属防腐方式,主要用于各行业的金属结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中,使钢构件表面附着锌层,从而起到防腐的目的。 热镀锌工艺流程:成品酸洗-水洗-加助镀液-烘干-挂镀-冷却-药化-清洗-打磨-热镀锌完工 1、热镀锌是由较古老的热镀方法发展而来的,自从1836年法国把热镀锌应用于工业以来,已经有一百七十多年的历史了。近三十年来,伴随着冷轧带钢的飞速发展,热镀锌工业得以大规模发展。下面跟着鑫顺金属制品来了解下福州热镀锌的防护性能与镀锌层形成原理:
