Here's how to clean up the Prepainted Steel Roll? Most of the coatings used to clean the color coated rolls can be used as solid lubricants, and can be assured of the moisturizing requirements of most molding processes. Some industrial paints can develop the wettability of the coating according to the adjustment recipe. If the wettability of the coating is not sufficient, the wettability can be developed according to the method of smearing, waxing, and coating off the original film. However, it should be noted that the wet lubricating fluid is easily sucked and cleaned and should be removed before the equipment. The original film can be removed as soon as possible after the renovation project.
Attention should be paid to the solubility and temperature of the cleaning solution during the Prepainted Steel Rollcleaning process. The solubility of the cleaning liquid is too low, the oil stain on the surface of the board is not cleaned, causing the subsequent coating to solve the defects and then jeopardizing the quality of the coating; the solubility is too high, the zinc and aluminum contained in the galvanized steel sheet are classified into two alloys, and the hot alkali content The surface of the zinc and aluminum layers in the liquid is easily composed of octoate, which produces an optimistic etch, which subsequently jeopardizes the subsequent biological coating effect.
Chemical cleaners usually have surfactants, and the best temperatures for setting up surfactants vary. When the temperature is too high, the reliability of the surfactant is lowered, the cleaning liquid can be reduced to remove the oil stain; if the temperature is too low, the saponification reaction rate is too slow to completely remove the oil stains, and together, more foam damage can be eliminated. In addition, the temperature of the cleaning liquid is too high to accelerate the etching of the zinc and aluminum layers when the liquid is added or removed. Prepainted Steel Roll
