Will The Antibacterial Stainless Steel Pipe Be Popular For Anti-coronavirus Campaign?
At present, the newest coronavirus virus has entered a high incidence period, and the hottest word is "antibacterial".
Can antibacterial stainless steel be antibacterial?
As the name suggests, antibacterial stainless steel has antibacterial effects, but why do you know that it is antibacterial?
Special metal elements are usually added to antibacterial stainless steel pipes. It is common to add "copper" to make stainless steel with antibacterial function. Compared with traditional stainless steel, copper-containing antibacterial stainless steel contains 0.5% to 1% more copper than traditional stainless steel.
Why does copper cause bacterial death?
Positively charged copper ions and negatively charged bacteria are easy to combine and interact, causing holes in the outer membrane of bacteria, viruses, and microorganisms; as the main protective membrane of the outer layer has been breached, the flow of Cu2 + can be smooth When ground enters the cell, Cu2 + is a heavy metal ion, which can destroy bacteria's protein and respiratory enzymes, hinder or destroy the activity of catalyst enzymes required for their metabolism, thereby inhibiting, killing and destroying bacteria, viruses and microorganisms.
Copper-added stainless steel has a strong bactericidal effect on E. coli and Staphylococcus aureus. When the copper content in stainless steel increases from 1.5% to 3.5%, the sterilization rate of stainless steel against E. coli increases from 75.2% to 99.9%, the sterilization rate of Staphylococcus increased from 80% to 99%.
After contacting the antibacterial stainless steel with E. coli, the copper in the rich phase on the surface dissolved out as CU + 2 and interacted with bacteria, resulting in bacterial death.
Can antibacterial stainless steel resist new coronavirus?
Antibacterial Stainless steel is no doubt antibacterial, so what exactly is antiviral? --Not necessarily
The answer is: Bacteria and viruses are two different things! Not only are bacteria and viruses significantly different in morphology, structure, or reproduction. Same as mentioned in the previous article "Will Coronavirus Survive On Stainless Steel Pipe ’s Smooth Surfaces?":
Another paper published in the American Journal of Applied and Environmental Microbiology in 2016 examined in more detail the survival of H1N1 influenza virus on stainless steel surfaces under different environmental conditions. Studies have shown that the virus can survive up to 7 days on stainless steel surfaces and still be infectious.
Overall: The virus survives relatively long on non-permeable (waterproof) surfaces such as stainless steel and plastic. Survival time on permeable surfaces such as fiber fabrics and paper towels is relatively short.
The survival time of different types of viruses is also different. Some viruses can survive on the surface of indoor objects for more than 7 days, but their pathogenic capacity will be significantly reduced within 24 hours.
At present, it is not clear how long the new coronavirus will survive indoors, so we must pay special attention to it.
