As we all know, in recent years, the application range of powder coatings is expanding, and the coating industry has become more and more strict with the content of volatile organic compounds. The use of water-based nano-antibacterial and anti-mildew coatings has also attracted more and more attention. Especially in some public places, such as the antibacterial effect of equipment and surface coatings used in hospitals, more stringent requirements have been put forward, so the demand for water-based nano antibacterial and antifungal coatings is constantly increasing. Next, the editor will lead you to understand the different processing processes of water-based nano antibacterial and anti-mildew coatings to help you better understand this product.

The water-based nano antibacterial and anti-mildew coating can be washed with water, and the antibacterial powder coating sample should be treated with water and water. It is necessary to use about 50 ml of tap water to wash the surface of the sample, and then add some washing liquid inside to wipe it, and then use The rag is wiped for nearly 50 times, and then the dirt on the surface is cleaned with tap water. After 50 times of washing, the antibacterial performance of the coating can be tested.

The water-based nano-antibacterial coating can also be treated with waste water. It can be directly placed in boiling water at 100 °C for two hours, and then placed for an hour to test its performance. The stability of the coating can be detected in a high temperature environment. . Ultraviolet light treatment can also be used. This kind of ultraviolet light aging treatment can be tested for 24 hours and 48 hours respectively before testing its antibacterial properties. The sample is directly placed in a constant temperature electric oven at 200 degrees Celsius for one hour and then tested for color difference. , to ensure the color stability of the paint.

In the selection process of antibacterial agents for antibacterial powder coatings, it was found that the antibacterial properties of the coatings after adding different antibacterial agents were inconsistent, and the antibacterial effect of silver ion antibacterial agents with glass mesh structure was better. Using internal extrusion and external mixing with 2% antibacterial agent, the prepared powder coating has excellent physical properties and excellent antibacterial properties. The coating still has excellent antibacterial performance after washing, boiling, high temperature and ultraviolet light treatment.

The water-based nano antibacterial and antifungal coating can be applied to the surface coating of metal structural parts, and the coated workpieces are suitable for use in different antibacterial environments. It can be used in daily necessities, home appliances (refrigerators, freezers, air conditioners, washing machines, etc.), auto parts, building materials, medical materials, food industry supplies, etc.; it can effectively protect the surface of materials, reduce the breeding of bacteria, and prevent the spread of diseases , With the existence of water-based nano antibacterial and antifungal coatings, it can effectively protect our personal safety and the durability of various products.
