Precautions for using printed color coated steel plate

The coating of the printed color coated plate is made of baked synthetic resin coating. When used outdoors, the coating will gradually deteriorate due to the influence of sunlight, temperature, and rain. Careful observation of the surface of the steel plate or gentle touch with your fingers reveals the presence of white powder, which is inevitable due to the powdering of the coating. However, choosing different types of coatings can delay the service life of pulverization. In addition, the service life of different areas such as coastal areas, industrial areas, and rural areas also varies. Once corrosion such as coating powdering and cracking occurs, it should be repainted to extend its service life.

The pigment of the printed color coating itself. The pigment is not finely ground and does not reach the specified fineness; Although detailed spot checks were conducted on the coating after procurement, it is still possible that it may occur in one type of coating; If the coating is not filtered or not filtered clearly before application, the filtering device or filter screen of the coating room’s liquid supply system should be checked for blockage and rupture; The coating room site is not clean, and dust and sand particles fall on the coating surface of the natural leveling section. The ventilation filter screen of the coating room should be cleaned or replaced; The temperature of each section of the furnace is low.

Printed color coated sheet is lightweight, beautiful, and has good corrosion resistance. It can be directly processed and is mainly applied in the advertising industry, construction industry, home appliance industry, electrical appliance industry, furniture industry, and transportation industry. Choose appropriate resins based on different usage environments, such as polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc.

The use of general printed color coated plate is mainly for temporary color steel rooms, and attention should be paid to the following situations in color steel rooms:

The use of general printed color coated plate is mainly for temporary color steel rooms, and attention should be paid to the following situations in color steel rooms:
1. Please do not use an open flame stove indoors.
2. When using doors and windows, please gently push and close them.
3. Do not randomly or attempt to disassemble any screws and components.
4. Do not jump or run upstairs.
5. For steel components that are prone to corrosion, regular rust removal and other maintenance work should be carried out.
6. The indoor floor should be 50mm higher than the outdoor floor, and the drainage ditch should be repaired outdoors.
7. It is not recommended for users to set up a bathroom in the activity room. If it is necessary to set it up in the activity room, please take anti-corrosion and waterproof measures.
