How is galvanizing a responsibility? Discussion on galvanizing process

Before doing a few tickets of galvanized steel pipe, also went to several local galvanized manufacturers. I found that galvanized as a metal plating process, the existence of surface is quite extensive. So, old meng studied this respect knowledge designedly, with everybody simple chat zinc-plating craft is how to return a responsibility.


First of all, what is electroplating?

Is using the principle of electrolytic plating on some metal surface on a thin layer of other metal or alloy plating process, is the use of electrolytic action made of metal or other materials adhered on the surface of the parts of a layer of metal film technique to prevent metal oxidation (rust), improve the wear resistance and electric conductivity, reflective resistance, corrosion resistance, copper sulfate, etc.) and create beautiful etc.


What are the differences between chrome, nickel and zinc plating?


Electroplating is divided into copper plating, gold plating, silver plating, chromium plating, nickel plating and zinc plating and other specific processes, in the field of manufacturing, especially for the most extensive application of zinc plating, nickel plating and chromium plating. And these 3 kinds of galvanized process is the cheapest, which also distinguish hanging plating, rolling plating, hanging plating expensive, rolling plating cheap.


About electroplating, we need to know:


Electroplating production is mainly based on sewage and heavy metal pollution in sewage. The state has strictly controlled the expansion of electroplating industry and cut it down year by year.

Our country electroplating processing is mainly zinc plating, copper plating, nickel plating, chromium plating, which accounts for 50% zinc plating, copper plating, chromium, nickel accounting for 30%.

If the use is to prevent rust, you can use galvanized or cadmium plating; If the focus is to prevent wear and tear, nickel or chromium plating is the best choice.

How is galvanizing a responsibility?

Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials for the purpose of beauty and rust prevention. It has low cost, anti - corrosion characteristics, the color of silver white. However, because Zn is a reactive metal that can react with acids, its corrosion resistance is generally poor compared with chromium and nickel plating. Galvanized process is mainly used in screws, circuit breakers, industrial supplies (such as galvanized steel pipes).
