The differences between electrogalvanizing and hot-dip galvanizing are as follows

The differences between electrogalvanizing and hot-dip galvanizing are as follows: 1. Different concepts of hot-dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is an effective way of metal anticorrosion, mainly used in metal structure facilities in various industries.
The rust-removed steel parts are immersed in molten zinc melted at about 500 ℃ to make the steel members adhere to a zinc layer on the surface, thus achieving the purpose of anticorrosion.
Electrogalvanizing, also known as cold galvanizing in the industry, is the process of using electrolysis to form a uniform, dense and well-bonded metal or alloy deposition layer on the surface of the parts.
Compared with other metals, zinc is a relatively cheap and easily coated metal, which is a low-value anti-corrosion coating, which is widely used to protect iron and steel parts, especially to prevent atmospheric corrosion and for decoration.
2. Different hot-dip galvanizing processes: finished product pickling-water washing-adding auxiliary plating solution-drying-hanging plating-cooling-pharmacy-cleaning-grinding-hot-dip galvanizing completion.
Electroplating zinc process: chemical deoiling-hot water washing-water washing-electrolytic oil removal-hot water washing-water washing-strong corrosion-water washing-electroplating zinc ferroalloy-water washing-water washing-polishing-passivation-water washing-drying.
3. There are many hot-dip galvanizing processes with different processes, which can only be immersed in the molten zinc bath after the workpiece is deoiled, pickled, soaked and dried, and can be put forward after a certain period of time. This is hot-dip galvanizing, like some hot-dip pipe fittings are processed in this way.
When electroplating zinc is processed by electrolytic equipment, it should be immersed in the solution containing zinc salt after removing oil and pickling, connect the electrolytic equipment, and precipitate the deposited zinc layer on the workpiece during the directional movement of positive and negative current.
4, the overall appearance of different hot-dip galvanizing is slightly rougher, which will produce process water lines, dripping tumors and other performance, especially one end of the workpiece is obvious, the whole is silvery white.
The galvanized surface is relatively smooth, mainly yellowish green, of course, there are colorful, cyan-white, white green light and other performance, the whole workpiece basically will not appear zinc tumor, caking and other phenomena.
