The principle of antibacterial stainless steel patented by Institute of Metals, Chinese Academy of Sciences is not complicated. It kills bacteria by continuously releasing copper antibacterial elements. Everyone who went to high school knows that CU will completely destroy the cell wall of bacteria, hinder their metabolism and make them unable to grow and reproduce.
The difficulty of this technology lies in how to make stainless steel continuously release CU antibacterial element 10 year, which can not only kill bacteria, but also ensure human safety. For this matter, experts from the Institute of Metals, Chinese Academy of Sciences worked tirelessly for 18 years, and finally succeeded in the research and obtained the national invention patent.
