There is a coating on the surface of the aluminum coil, which plays an important role in "anti-corrosion". Let's talk about how the anti-corrosion operation of the aluminum coil is done? Brushing can use various coatings, as long as it is not a coating with poor leveling, this process mainly allows the coating to penetrate into the pores of the metal surface, which can enhance the metal adhesion. In this step, the requirements are high, and the paint with high liquid purity and high viscosity should be used, and attention should be paid to the common problems of the paint (cracking, falling, rolling, etc.).
Dip coating is a traditional coating method, which easily causes air pollution. Do not use volatile coatings. Flow coating is to spray the coating on the surface of the coating. Although the operation is simple and the production efficiency is high, the consumption of the spray coating is larger than that of the dip coating, which will cause the problem of dip-dye, which must be paid attention to.
The advantages of spraying are that the thickness of the coating is uniform, the appearance is smooth, and the production efficiency is high. Hot water rinse. Hot water washing is intended to age the film. However, the water temperature should be strictly controlled at all times. If the water temperature is too high, the film layer will be thinned and the color will become lighter. The above-mentioned similar problems will also occur when the industrial thermal insulation aluminum plate is processed for a long time. The suitable temperature and time are: 0.5~1MIN. when the temperature is 40~50℃. For drying, it is better to dry it naturally. The workpieces washed with hot water are hung on the shelf diagonally, so that the free water on the surface of the work will go down in a straight direction. The water droplets that flowed to the lower corners were sucked up with a towel, and the color of the film layer dried in this way was not affected and looked natural.
