Aluminum plate hardware cleaning method

"Abrasion method for aluminum plate hardware"
Aluminized plate, also known as aluminized steel plate. It is also known as an aluminized sheet or a hot dip aluminized sheet. It is a steel plate coated with an aluminum-silicon alloy, in which the aluminum content is 90% and the silicon is 10%. It has good heat resistance, heat reflection and corrosion resistance. Its mechanical and physical properties are superior to cold-rolled steel sheets, and it is widely used in household appliances and auto parts.
Aluminized plate hardware generally uses a relatively high-slurry processing oil during processing, so the cleaning dose is relatively consumed in the subsequent cleaning. Therefore, more water-based cleaning agents are used for cleaning from the cost. The general cleaning process is: 5% Evergreen peak cleaning agent cleaning----rinsing----rinsing----drying.
According to the technical department of Evergreen Chemical Company, the coating of aluminum plate is aluminum, aluminum is an amphoteric metal, can react with acid and react with alkali, so the cleaning of aluminized plate should use neutral detergent. At present, the neutral detergents on the market must be truly identified from the technical parameters. If some businesses are also said to be neutral, but in fact the PH value is around 8, such a cleaning agent can only be said to be a weak alkaline cleaning agent, perhaps the business will say neutral neutrality and other deception of the outsider. Everyone knows that the true neutrality should be a pH of around 7. If a weak alkaline cleaning agent is used, no problem will be found in the absence of comparison, but after a period of storage, it will be found that the gloss of the product cleaned with the neutral detergent will be dark, or even some without rinsing. A good place will have a yellow spot and the salt spray will be much worse.
How to choose a cleaning agent, in addition to the above mentioned PH value is really neutral, should consider a cleaning power, service life. The best way to choose is to try it out. General cleaning agent manufacturers will provide some samples of cleaning agents for customers to try, which is the best way to test cleaning agents.
