Coated steel mass control links and mass projects?

1. What links are usually included in the quality control of color-coated panels?

Answer: The quality control of color-coated plates is actually an extension of the quality control of the legal layer mentioned in Question 4-1. Coating control refers specifically to the quality control of each process in the production process after the steel strip is put on the machine.

Answer: Coating raw materials mainly refer to three items such as degreasing agent, chemical liquid, and coil coating.

The quality control of degreasing agent mainly refers to: cleaning ability, defoaming performance, emulsifying performance, rinsing performance, corrosion performance to metal.

The quality control of chemical liquid mainly refers to three indicators: appearance, film weight or film thickness and turbidity resistance.

The quality control of paint removal and board removal mainly refers to how to evaluate the state of the paint by visual inspection after the paint enters the warehouse; how to take relevant measures to prevent the paint from becoming sick during the storage process and to use various instruments in the laboratory before putting it on the machine The performance of the coating product is inspected in several aspects such as viscosity, fineness, solid content, color and density.
