Color steel coil processing technology introduction

Nowadays, there are many manufacturers producing color steel coils, and the application range of color steel coils is very wide, and they are very popular among people.

Regarding how to deal with the color difference problem of color steel coils, people use gas in the production line equipment to supply the temperature of the drying box, so that the temperature of the drying box is balanced, and the time range temperature difference is not easy to occur, and the paint must be evenly balanced before production. Regarding the missing coating of the color steel coils, people can know that the missing coating is caused by the substrate swimming, deformation, air oxidation, etc. under the detailed introduction of the relevant staff.

Color steel coils use high-quality substrates. No matter which painting process is selected, the technical standards for substrates are getting higher and higher. Most steel-based color steel coils require flattening spangles, zero-spangle hot-dip galvanized steel coils or phosphating steel coils. In recent years, it has been upgraded to use hot-dip galvanized aluminum, aluminum-zinc and other aluminum alloy coated thick steel plates as substrates. The development trend of the glass film color steel coil is cold rolled as the substrate, and some high-end products also use stainless steel as the substrate. No matter which substrate is selected, there are very high requirements for its surface layer, board type and specification accuracy.

Improve the normalized processing technology. The normalized processing makes the substrate and the architectural coating more inextricably coordinated with each other. The selection of the new normalized processing processing system software can improve the reliability of the normalized processing liquid and improve the color steel Anti-corrosion and flexibility of the roll, together to reduce air pollution.
