Galvanizing is divided into cold galvanizing and hot galvanizing:
1.Cold galvanizing: Cold galvanizing is a cathode that has been degreased and rust-removed, showing a non-staining and wetting, and is placed in a special plating tank. The anode is zinc. The DC power is turned on, the zinc ions on the anode migrate toward the cathode, and discharge on the cathode, so that the workpiece is plated with a zinc layer. It is suitable for repair work (that is, in the process of repair work, only in the damaged surface of the protected steel, as long as the surface is repaired, it can be recoated). The cold spray zinc process is used for the corrosion protection of various steel products and structures.
2.Hot galvanizing: Hot galvanizing is a surface that removes oil and rusts and presents a non-staining and wetting surface. It is immediately immersed in a plating tank that has previously been heated and melted by zinc. A method of forming a zinc coating on the surface of the workpiece.
Painting: Painting is a method of applying a uniform and fine mist droplet to a surface of an object to be coated by means of air pressure by means of a spray gun. Water-resistant, oil-resistant, fast-drying, used in paint cars, airplanes, wood, leather, etc. The substance is toxic and has a certain impact on the body. Different brands of paints have different toxicity due to different ingredients. Special care should be taken when using it to avoid inhalation and skin contact.
