Galvanized steel coils in China have been widely used for a long time. Its application type is very good. Many chinese ppgi colour coated sheet manufacturer attach great importance to the future of this product, so there will be a variety of products. Therefore, consumers will have concerns when choosing Chinese galvanized steel coils. How to choose china galvanized sheet coil correctly?
Here is a brief and detailed introduction:
In recent years, the types of galvanized steel coil products in China have undergone rapid transformation and development. The demand for this product is constantly increasing, and when choosing products, it is important to pay attention to the relevant characteristics of the product.
Most coatings can be used as solid lubricants and can meet the wetting requirements of most forming processes. Some industrial coatings can adjust their wettability based on the development trend of ancestral secret formulas. If the wettability of the coating is insufficient, the trend of wettability can be eliminated by oiling, waxing, and coating. However, it is important to pay attention to the simple suction of lubricating oil, which should be eliminated before using the machine and equipment. The original film can be removed as soon as possible after the completion of the project decoration.
Here is a detailed explanation of how to remove color rolls
01
During the cleaning process, it is important to pay attention to the solubility and temperature of the cleaning solution. Due to the low solubility of the cleaning solution, the oil stains on the surface of the board were not cleaned, resulting in defects in the subsequent edge coating treatment, thereby damaging the coating quality; Due to their high solubility, the iron and aluminum in galvanized sheets belong to dual aluminum alloys, and the surfaces of the zinc and aluminum layers simply form a heartate in a hot alkaline solution, which raises concerns about corrosion and further damages the subsequent edge molecule biological coating effect.
02
Organic chemical cleaning liquids generally contain surfactants. The best way for different surfactants to produce high efficiency is to have different temperatures. If the temperature is too high, it will reduce the credibility of the surfactant, thereby reducing the removal of oil stains in the cleaning solution. If the temperature is too low, the Saponification speed is too slow to completely remove the oil stains, which together will cause greater foam damage and removal effect. In addition, excessive temperature of the cleaning solution can cause corrosion of the zinc and aluminum layers
