Color coated coil board has already been applied to all aspects of people's clothing, food, housing and transportation. Many people should find that the paint will fall off in the whole process of application. This problem seriously endangers the application and beauty of color coated boards. Then why does the paint fall off on the coil of color coated boards of PCM household appliances?
Firstly, color coated steel plate is a kind of steel plate with organic coating. Color steel plate is divided into veneer, color steel composite plate, floor bearing plate, etc. It is widely used in the walls and roofs of large public buildings, public factories, movable plank houses and integrated houses. Color steel plate coating is a product made of cold rolled steel plate and galvanized steel plate, coated (roll coated) or composite organic film (PVC film, etc.) after surface chemical treatment, and then baked and cured. Some people also call this product "pre roll coated color steel plate" and "plastic color steel plate". Color plate products are produced by the manufacturer in coils on the continuous production line, so they are also called color coated steel plate coils. Color steel plate not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials. Color steel plate is a new material respected in the world. With the progress of science and technology, the enhancement of environmental awareness and the improvement of people's living standards, color steel plate movable houses show more and more strong vitality and broad market prospects, and are favored by construction, household appliances, electromechanical, transportation, interior decoration, office appliances and other industries.
① In the whole process of production and manufacturing of color coated plate, there is dust on the inspection mirror at the entrance and exit, and also on some rollers. The dust will immediately endanger the process performance of color coated plate. It may not be able to show at the beginning, but once the time is long or exposed to too much sun, the paint will fall off.
② The production process of passivation treatment plate temperature is required to be checked every 2 hours, which means that the staff of the color coated plate manufacturer did not track the passivation treatment plate temperature regularly during the inspection. Especially in winter, the temperature changes greatly within 2 hours, which will eventually lead to the timeliness of the color coated plate. At that time, the paint will be scratched and removed.
③ Passivating agent shall be added before water is discharged during tank preparation. Because the relative density of passivator is difficult, for example, when the relative density of passivator is higher than water, it will lead to uneven mixing of raw materials, poor adhesion between passivation treatment layer and base steel plate, and it is easy to paint off the surface of color coated plate.
