The times are developing. Today's rural areas and second-tier cities have a high standard of quality of life requirements, and their purchasing power has also increased, which is undoubtedly a huge business opportunity for the top ten brands of PPGL coil. The tailor-made, high-quality PPGL coil products not only satisfy their curiosity about new products, but also enhance their desire to buy. The purpose of using the milky white topcoat is to reduce the thickness of the paint. Since all the normal anti-corrosion topcoats for color-coated panels are light green (thus sulphuric acid paste), it is necessary to have any thin paint thickness. Paint adhesion. In that case, the corrosion resistance is very risky. The first coat is poor in corrosion resistance, and the paint is greatly thinned, not enough 12 mm.
The selection of PPGL coils for critical selection of materials not only allows for application regulations, but also allows for greater control costs. If the selection of materials is not good, the result will be that the characteristics of the raw materials exceed the application regulations, resulting in excess extravagance and waste, and will not be able to meet the application regulations, resulting in relegation or no application. Therefore, the buyer should pay attention to the necessity of effective material selection. PPGL coil plays an important role in the engineering construction industry. The key to the application of PPGL coil in the construction industry is the wide coverage of the engineering building exterior frame structure and the interior decoration of the engineering building. The types of color-coated plates used in the construction of the outer frame structure of engineering buildings are also divided into various types. Among them, the single-sided pressure-type plate color-coated plates are mostly used for roofs and walls, and the two-layer color-coated plates are sandwiched between the middle and the middle. Insulation sandwich panels made of wood are used for buildings that must be insulated.
Because the light wavelength of the PPGL coil source is less, the kinetic energy it contains is higher. According to this basic theory, the aging of PPGL coil in atmospheric pollution is that the molecular structure of the coating absorbs and absorbs the kinetic energy of the ultraviolet band in the natural light higher than the bond energy of its molecular structure, resulting in dissolution of the molecular structure of the coating. With the aging of the polyurethane coating, the base material itself is slowly missing, and the surface layer of the coating gradually becomes unsmooth and loses light. This type of loss of the base material leaves a relatively smooth paste body, which remains in the unbonded powder form to the surface of the polyurethane coating. This process is called delamination. The window doors made of PPGL coil are also very wide. For other engineering construction parts such as drain pipes and seals, professional color coated coils are also used. Such a color-coated steel plate looks glamorous and bright, and it will cause etch (invasion, bending, under-film, etc.) in different areas in less than 2 years.
