Because now the weather is getting colder and colder, a lot of places a lot of different types of ppgl have appeared the phenomenon of exploding paint, so this is really the weather, in fact, is not all, today, we will tell you the reason.
1, passivated plate temperature production process is to check every 2 hours, the reason is that the staff did not regularly track the passivated plate temperature during the inspection. Especially in winter, the temperature change within 2 hours is also relatively large, which will eventually cause color coating aging and scratching phenomenon when pressing words.
2, color coating roller production process, there is dust on the export inspection mirror, part of the roller dust. Dust will directly affect the surface quality of color roller.
3. When pairing, add passivation solution first, then add water. Because the density of the passivation liquid is larger, such as the density of the passivation liquid is higher than that of water, the raw material will be mixed unevenly, the adhesion of the passivation layer and the base material is poor, and it is easy to make the color coating surface spray painting phenomenon.
We should have a certain understanding of the phenomenon of color coating roller explosion paint, so, or to standardize the operation, serious operation, the production of high quality products. Color aluminum plate has been widely used in the construction industry, and has played an important role in the development of modern architecture to the direction of comfort, lightness, durability, economy and environmental protection. Due to moderate structural strength, weather resistance, corrosion resistance, fire resistance, acid and alkali resistance, heat insulation and other advantages, it is recognized as the design life of more than 20 years of roofing and exterior wall materials.
Ppgl and aluminum and the advantages of organic materials, has both aluminum sheet of high mechanical strength, good toughness, easy to processing molding performance advantages, such as good color and adornment sex, corrosion resistance of organic polymer coating material, can be convenient to carry on the blanking, bending, deep drawing, welding processing, products made of practical, adornment sex is strong, easy processing. Color aluminum plate is widely used in industrial plants, stations, airports, stadiums, commercial buildings, residential buildings and other buildings and household appliances manufacturing industry. It has been widely used in foreign countries. With the continuous rapid growth of China’s economic construction, the application fields and demand of domestic color aluminum plate have been expanding in the past decade. Because of its wide use, simple processing, long service life, light weight (proportion of iron plate 1/3), low unit cost, clean coating anti-fouling, colorful, green environmental protection and other characteristics and gradually become the color aluminum plate industry in the future development direction, large market demand. Full capacity is 3,000 tons per month
