Antibacterial mechanism of antibacterial powder coating
In daily work, people spend most of their time indoors, so the hygiene of the indoor environment should be paid attention to. In particular, objects used indoors are often attacked by harmful microorganisms such as bacteria and molds. When harmful bacteria come into contact with the human body, various diseases can be transmitted, threatening human health. Therefore, antibacterial materials play an increasingly important role in construction and interior decoration. Among them, antibacterial coatings can be directly sprayed on the surface of various materials, and the ease of use is even more eye-catching.

In daily work, people spend most of their time indoors, so the hygiene of the indoor environment should be paid attention to. In particular, objects used indoors are often attacked by harmful microorganisms such as bacteria and molds. When harmful bacteria come into contact with the human body, various diseases can be transmitted, threatening human health. Therefore, antibacterial materials play an increasingly important role in construction and interior decoration. Among them, antibacterial coatings can be directly sprayed on the surface of various materials, and the ease of use is even more eye-catching.
Antibacterial refers to the process of using chemical or physical methods to kill bacteria or hinder the growth and reproduction of bacteria and their activity. Antibacterial powder coating refers to the addition of antibacterial materials during the coating manufacturing process, which can inhibit it for a long period of time. Bacteria grow and multiply, a new type of functional coating that has sustained antibacterial effect.
Most of the antibacterial components in antibacterial materials are silver. What is the mechanism of silver antibacterial?
Silver can be antibacterial, but many people don't know how silver is antibacterial. There are two main mechanisms for its mechanism of action.
The principle of contact reaction sterilization, silver ions contact with cells and react, causing the inherent components of the bacteria to be destroyed or dysfunction, causing the bacteria to die and unable to grow and reproduce. The main reason is that most of the cell membranes of microorganisms are negatively charged, and silver ions are positively charged, which can be firmly adsorbed on the cell membrane by Coulomb attraction, and can further penetrate the cell wall into the bacterial cell membrane, and carry out sulfhydryl reaction with the bacteria. The protein coagulates, destroys the activity of bacterial cells and enzymes, and causes the cells to lose their ability to divide and reproduce and die. Silver ions can also destroy the microbial electronic transmission system, respiratory system, and material transmission system. When the bacterial cells lose their activity, the silver ions will be released from the cells again, and the sterilization activities will be repeated to achieve a long-lasting antibacterial effect.
Another bactericidal argument is the catalytic reaction method. Under the action of light, silver ions and nano-scale particles can act as catalytic active centers, activate water molecules and oxygen in the air, and form free radicals. These groups can destroy the value-added ability of bacteria in a short time and cause cells Death, so as to achieve the purpose of antibacterial.
There is no obvious conclusion on the sterilization mechanism of silver ions. Usually, the first type is the main antibacterial mechanism, and the photocatalysis only plays a certain role.
