Nano silver PET copper antibacterial protective film for elevator
Application
Antibacterial mechanism:
1. The bactericidal ability of nano-silver is 100 times that of ordinary elemental silver (the surface area of nano-level element is larger), and the bactericidal substance we choose is nano-silver-copper alloy element (silver-copper ratio 3:1) but it is It is twice as fast as nano-silver and has a faster sterilization speed and a stronger ability to inhibit bacteria. Silver-copper alloys have also achieved medical consensus on the killing of viruses.
2. Our nano-silver-copper element and hardened resin are completely dissolved. After curing, they are filled with resin and embedded in the entire resin. Since the nano-silver-copper group is negatively charged, it has strong antioxidant capacity and silver The copper alloy itself is anti-oxidation, even if it is slightly oxidized, the product is sterilizing. The additives we choose make the silver and copper elements difficult to agglomerate, and the silver and copper nanoparticles are 7-20 nanometers. The average value is 15 nanometers, and each nano-group particle has tens of thousands of silver and copper particles.
3. Generally, silver-containing substances have a sterilization ability at a unit of 10 ppm, and we have made a concentration of up to 500 ppm on the surface of the film cured resin. The groups on the surface of the film continuously release silver and copper elements to interact with bacteria and viruses. After the silver and copper substances penetrate the cell wall, they will react with the ribonucleic acid amino groups and sulfur groups of the virus and bacteria to covalently react with the CL elements contained in the sweat of the hands. Equivalence (the ionic state is generated due to the humidity of the air and the moisture on the contact surface, sweat, etc.). After the wall is broken, the nutrient solution in the cell flows out and kills the bacteria.
4. Each nano-group contains tens of thousands of silver and copper elements that are continuously released to react with the release, which is different from the traditional phosphate bactericidal properties. Phosphate is a pure ion with a limited content of bactericidal content, and there will be no after the surface is released. . The properties of ordinary silver ions are similar. And the initial state is that the ionic state is unstable and easy to decompose.
5. As far as possible, do not clean the surface with a high acid content disinfectant, otherwise the silver copper alloy will be washed away. Generally, cleaning with clean water and alkaline conditions is not harmful, and the solution with low acid content is not a problem.
6. Long-lasting and long-lasting sterilization, the surface can achieve high wear resistance, scratch resistance and high hydrophobicity.
