PPGI PPGL color difference problem For color steel coil how to control the color difference problem, our production equipment uses natural gas for the oven temperature, so the oven temperature is balanced, there will be no temperature difference in the time period, and the paint must be evenly adjusted before production. For the control of color steel coil leakage coating, we can understand that the leakage coating is caused by deformation and oxidation of the substrate.
PPGI PPGL use high-quality substrates, no matter which coating process is adopted, the technical requirements for the substrates are getting higher and higher. Most steel-based color steel coils require flat zinc flower, zero-zinc flower hot-dip galvanized steel coil or electro-galvanized steel coil. In recent years, there has been a trend to increase the use of hot-dip galvanized aluminum, aluminum-zinc and other alloy-coated steel sheets as substrates; Cold rolled coils are used as substrates, and some high-grade products are also made of stainless steel. No matter which substrate is used, it has high requirements on its surface, shape and dimensional accuracy. Improve the pretreatment process, pre-treat the substrate and coating more closely, adopt a new pretreatment process system, increase the stability of the pretreatment liquid, enhance the corrosion resistance and flexibility of the color steel coil, and at the same time reduce the environmental pollution .
Analysis of the characteristics of the PPGI PPGL saves time and effort: the color steel plate color steel plate room is very light, the splicing installation and the optional laser cutting feature, the installation of the Delphi method color steel plate room can be a lot of savings To save the progress of the project. The surface material and wall insulation material of the safety fire-fighting color steel coil sandwich panel are non-combustible materials, which can fully meet the fire protection requirements of the color steel plate room.
PPGI PPGL has a clear decorative line and a variety of colors, which can be harmonized with any style of color steel plate building, beyond the peace of mind. Insulation and heat insulation: The color wall steel composite rock wool board generally has wall insulation materials such as rock wool, glass fiber cotton, polyethylene, polyurethane, etc., and the thermal conductivity is low, so that the color steel plate room has high quality thermal insulation effect. The high-strength color steel roof is made of high-strength steel sheet with the best layout and roll forming. Therefore, the color steel plate color steel plate room has good structural characteristics.
