1. Definition

 

pvc pipe for water supply supplier refers to a steel plate with a layer of zinc on the surface. Galvanizing is an economical and effective anti-corrosion method. The zinc layer is firmly attached to the steel plate substrate through hot-dip or electro-galvanizing processes. Hot-dip galvanizing is to immerse the plated steel plate in molten zinc liquid, so that the zinc liquid forms a zinc-iron alloy layer and a pure zinc layer on the surface of the steel plate; electro-galvanizing is to deposit zinc on the surface of the steel plate to form a zinc layer through electrolysis.

2. Advantages

 

(I) Corrosion resistance

 

Zinc forms a dense zinc oxide film in the air, which prevents oxygen and moisture from further corroding the steel plate. When the zinc layer on the surface of the galvanized steel plate comes into contact with the external environment, the zinc will undergo oxidation reaction before the iron, thus protecting the steel plate substrate from corrosion. In a normal atmospheric environment, the galvanized layer can provide effective anti-corrosion protection for up to decades. Compared with ungalvanized steel plates, its anti-corrosion life can be significantly improved, greatly reducing the cost and resource waste caused by replacing steel plates due to corrosion.

 

(II)Good processing performance

 

During bending, stamping and other processing, the galvanized steel plate will not crack due to the presence of the zinc layer, and can maintain good processing performance.

 

(III) Weldability

 

 Welding operations can be carried out more conveniently, and the welded parts can still maintain good rust resistance.

3. Feature

 

(I)Appearance: The surface is smooth and has a metallic luster. The galvanized layer is uniform, making the steel plate look more regular as a whole.

 

(II)Strong adhesion: The zinc layer has good adhesion to the steel plate substrate and is not easy to peel off.

 

4. Application

 

(I)Construction industry: used for building structural parts, such as roofs, walls, curtain walls, etc. It can effectively resist wind and rain erosion in outdoor environments and maintain the appearance and structure of the building.

 

(II)Automobile manufacturing: used on some automobile exterior panels and chassis parts to improve the corrosion resistance of automobiles and reduce maintenance costs.

 

(III)Home appliance field: used to make the shells of home appliances such as refrigerators and washing machines. Due to frequent contact with water and different climatic environments, galvanized steel sheets can ensure that the shells of home appliances are not easy to rust, improving product quality.
