What is the material of color coated steel plate

Coated steel plate refers to the products coated with tin, zinc, aluminum, chromium, lead tin alloy, organic coatings and plastics on the surface of low carbon steel plate with good deep drawing performance. Colored coated steel plate belongs to a kind of coated steel plate, which is coated with colored organic coatings or films on the surface of galvanized steel plate, aluminum plated steel plate, tinned steel plate or cold rolled steel plate.

Color coated steel plate is galvanized steel plate or cold rolled steel plate as the matrix, after surface treatment coated with a variety of protective, decorative coating, commonly used coating is divided into inorganic coating, organic coating and composite coating three categories. The structural layer of color coated steel plate from inside to outside is cold rolled plate, galvanized layer, chemical conversion layer, initial coating (primer), fine coating (positive and back paint).

Two, what are the types of color coated steel plate

Color coated steel plate referred to as color coated steel plate, this kind of plate surface color novel, strong adhesion, corrosion resistance and decorative good, and good processing performance, so it is widely used in building external wall panels, roof panels, corrugated panels, waterproof and anti-air penetration board, corrosion resistant equipment and components and furniture, car shell, water baffle board. According to the different structure, color coated steel plate can be divided into the following types:

1. Coating steel plate

With galvanized steel plate as the base, the front and back of the coating, to ensure its corrosion resistance. The first coat on the front is primer, usually epoxy primer because of its strong adhesion to the metal, and the back is also coated with epoxy or acrylic resin; The second layer (surface layer) used alkyd resin, generally with polyester coatings or acrylic resin coatings.

2. PVC steel plate

PVC layer is thermoplastic, the surface can be hot processing, such as embossing can make the surface texture rich, but it also has flexibility, can be bent and other secondary processing, its corrosion resistance is also better. There are two types of PVC steel plate, one is the production of coated paste PVC method, called coated PVC steel plate; The other is to have been formed and printed or embossed PVC film on the steel plate, known as the film PVC steel plate.

3, heat insulation coating steel plate

Heat insulation coating steel plate is pasted with 15 ~ 17mm thick polystyrene foam or rigid polyurethane foam on the back of color coated steel plate, which is used to improve the performance of coated steel plate. It is mainly used for special fields that need heat insulation and sound insulation.

4, high durability coated steel plate

The durability and corrosion resistance of color coated steel plate can be improved by applying the high durability coated steel plate to the surface coating of steel plate with good aging resistance of fluorine plastic and acrylic resin.
