Antibacterial clean board is a kind of metal paint plate color board which is coated with special enamel series antibacterial agent.
Because the special enamel series antibacterial agents are reused in the coating, it has non-toxic and semi permanent antibacterial effect and far infrared radiation effect, and can produce more than 99% antibacterial rate against coliform and Staphylococcus aureus.
The thickness is 0.17-1.5mm, and the width is below 1250mm. The base plate is galvanized and aluminized zinc. The coating structure is 2 / 2, 2 / 1 or 2 / 0 (2 / 1 in general, i.e. two coating on the front and one coating on the back). The film thickness is 20-25um / 5-10um, the single coil weight is ≤ 10t (4-5t / coil in general). The inner diameter of color steel coil is Φ 510mm / 610mm, the outer diameter is Φ 800-1500mm, and the service life is 10-20 years.
Antibacterial color coated steel plate and special finish design can kill common bacteria such as Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa, avoid environmental pollution caused by bacteria and mold reproduction, and reduce the impact on human health.
The key technology of antibacterial color coated steel plate is the silver ion in its top coat.
The specific mechanism is as follows:
1. Interfere with the synthesis of cell wall. The interference effect of silver ion antibacterial agent on cell wall mainly inhibits the linkage between polysaccharide chain and tetrapeptide, which makes cell wall lose integrity, lose the protection effect on osmotic pressure, damage the cell wall and die.
2. Damage cell membrane. Cell membrane is an important part of bacterial cell life activities. If the cell membrane is damaged, it will lead to bacterial death.
3. Inhibit the synthesis of protein. The process of protein synthesis changes, stops and kills bacteria.
4. Block the replication of genetic information, including the synthesis of DNA and RNA, and DNA template transcription mRNA.
Industry characteristics: the food and drug industry belongs to the national special supervision industry, which has extremely strict requirements on the health environment of the production workshop. Unqualified health environment will directly affect the safety of food and drugs.
Application: due to the use of special enamel series of antibacterial agents in the coating of antibacterial color plate, it has non-toxic and semi permanent antibacterial effect and far infrared radiation effect, and can produce more than 99% antibacterial rate against coliform and Staphylococcus aureus, which is widely used in the fields of pharmaceutical, food processing and other fields with strict antibacterial requirements. At the same time, easy to clean color plate is widely used in food and drug industry because of its good hydrophilic property and easy to clean surface. Therefore, the food and drug industry recommends the use of antibacterial color plate or easy to clean color plate.
