Color roller has been widely used for a long time. Its application type is very good. Many manufacturers attach great importance to the future of this product, so there will be a variety of products, so when consumers choose the color roller, they will
have concerns about how to choose the color roller correctly. Here is a brief and detailed introduction:
In recent years, the change and development of the product type of color roller is quite rapid. In recent years, the demand for this product is increasing, but there is a lack of high-quality basic steel plates such as zinc free integrated tablet computers
and die-casting aluminum alloy coating rolls. The variety and quality of domestic industrial coatings can not fully meet the requirements. The price of imported industrial coatings is too high, which reduces the market competitiveness. The plastic mould
for pasting the color toughened film plate needs to be made of imported materials, lacking high-grade color roller with thick coating, strong function, high wear resistance and good pattern. Therefore, when purchasing goods, we must pay attention to the
relevant characteristics of the goods and help you to select the color rol
Most coatings can be used as solid lubricants and meet the wetting requirements of most forming processes. Some industrial coatings can adjust the wettability of coatings
according to the development trend of ancestral recipes. If the wettability of the coating is not enough, the development trend of wettability can be eliminated by oiling, waxing and coating. However, pay attention to the simple absorption of wet lubricating
oil, which should be eliminated before using the machine and equipment. The original membrane can be removed as soon as possible after the completion of the project decoration?
In the cleaning process, pay attention to the solubility and temperature
of the cleaning solution. Due to the low solubility of the cleaning solution and the unclean oil on the surface of the plate, the subsequent edge coating treatment will be defective, which will damage the coating quality. Due to the high solubility, the
iron and aluminum in the galvanized plate belong to the double aluminum alloy. However, the surface of zinc layer and aluminum layer simply forms a kind of heart acid salt in hot alkali solution, which causes people to worry about corrosion, and then
destroys the subsequent edge molecule biological coating effect.
Organic chemical cleaning fluid generally contains surfactants. The best way for different surfactants to produce high efficiency is to have different temperature. If the temperature
is too high, the credibility of surfactants will be reduced, so as to reduce the removal of oil in cleaning solution. If the temperature is too low, the saponification reaction rate is too slow, and the oil stains can not be thoroughly removed. Adding
together will cause greater foam damage and removal effect. In addition, too high temperature of cleaning solution will accelerate the corrosion of zinc and aluminum layer.
