During the production and development of the color-coated board, we will touch the impurities in the ambient air. After such a long time, our teachers must clean it regularly. We often use it in our lives to clean and degrease and use various chemical cleaning agents. Take a look at the following issue. Degreasing cleaning is the use of dissolved solutions, saponification, emulsification, industrial chemical cleaning with important moisture, and mechanical action to degrease and impregnate the appearance of the substrate, foreign particles.

　　Now, the chemical professional cleaning solution used in the production line of most enterprises is mainly composed of complexing agent, different active agents on the surface, sodium hydroxide, potassium hydroxide, polyphosphoric acid and other ingredients, which are alkaline environmental solutions. The cleaning and degreasing effect mainly depends on the concentration of the cleaning solution, temperature and steel strip cleaning time. The cleaning process is to pay attention to control the concentration and temperature of the cleaning solution.

　　The concentration level of the cleaning solution is too low, and the oil stains on the surface of the substrate are not cleaned cleanly, resulting in some shortcomings in the back-side chemical coating treatment problem and then affecting the technical quality of the research coating; if the concentration is too high, the zinc and aluminum contained in the galvanized sheet are attributed to amphoteric metals. In the hot alkali solution, the surface of the zinc and aluminum layers can be simply systematically formed into heart acid salts, forming more severe corrosion, and then directly affecting the later learning of chemical coating.

　　Chemical cleaners usually contain an external active agent, and various external reagents make a difference in temperature performance. If the temperature requirements are too high, the stability of the surface active agent will continue to decline, which will reduce the ability of the cleaning liquid to remove oil stains; if the temperature is too low, the saponification reaction will develop relatively slowly and cannot completely eradicate oil stains. At the same time, there will be many problems. Foams will affect the data cleaning effect.

　　In addition, the high temperature of the cleaning solution will accelerate the corrosion of the zinc and aluminum layers. The above are the cleaning methods that color-coated board manufacturers can often use. As long as we insist on the cleaning of the color-coated board during the use process, we will not delay the use of the color-coated board and ensure the normal use of the product to improve production efficiency!
