一、热镀锌产品表面缺陷对镀层耐蚀性的影响我厂热镀锌(以下简称镀锌)生产是通过一套完整的工艺流程最后以单梁双钩吊车浸锌操作实现的,其主导产品是不同规格船用异形钢管和输电线铁塔。产品常见表面质量缺陷对镀层耐蚀性的影响有以下九方面: 漏镀指局部没有镀锌层而露出坯料原表面。当露出部分很小时,由于锌的牺牲阳极保护作用对耐蚀性没有多大影响。但锌的
First, the hot dip galvanized surface defects on the corrosion resistance of the coating My factory hot dip galvanized (hereinafter referred to as galvanized) production is through a complete set of process flow Finally, single-beam double hook crane Zinc Zinc operation to achieve its leading product Is different specifications ship shaped steel pipe and power transmission tower. The common surface quality defects of the product have the following nine aspects on the corrosion resistance of the coating: Leakage-free means that there is no zinc coating on the surface to expose the original surface of the billet. When the exposed part is small, the sacrificial anode protection due to zinc has little effect on corrosion resistance. But zinc
