New antibacterial stainless steel bacteria suppression rate of 96%

ever wondered that one day we have a stainless steel milk cup in our hands with "immune function" and don't even have to worry about bacteria? Now, scientists have come true to this dream for usLast weekend, China's independent innovation research and development of new antibacterial stainless steel ——— antibacterial oxide film stainless steel and its processing technology, officially through the expert identification in BeijingThe product in Changzhou City, Jiangsu Province, Daping new stainless steel products Co, Ltdto achieve industrial productionAntibacterial stainless steel is a new material that intersects material science and environmental scienceAt present, the market is widely used antibacterial stainless steel coated antibacterial stainless steel, alloy type antibacterial stainless steel and composite antibacterial stainless steel threeAccording to the project leader Professor Zhou Guoxuan, antibacterial oxide film stainless steel using the above three antibacterial stainless steel completely different production process, the process put the stainless steel material in the acid solution containing silver medium, through a special current (positive and negative cross-variation) at 40-50 degrees Celsius to electrify about 6 to 10 minutes, the material surface is formed a thickness of about 200 to 300 nano-structure of large-molecule oxide film, this structure is a typical gem-type crystal structureCompared with coated antibacterial stainless steel, antibacterial oxide film stainless steel has good processing performance, can withstand 180 degrees of bending and deep elongation, molding processing, not only suitable for making plates, strips, wire, etc., but also suitable for a variety of sizes and sizes of special parts, almost not limited by materials, but also not limited by the size and shape of parts, greatly expanding the application range of antibacterial stainless steelBy the NanjingDiseasePrevention and Control Center test, antibacterial oxide membrane stainless steel 6-hour antibacterial rate can reach 96%, and Japanese data show that alloy-type silver antibacterial stainless steel 15 hours of anti-bacterial inhibition rate can reach 90%At the same time, the Chinese Academy of Sciences Institute of Science and Technology, antibacterial material testing center results show that the antibacterial oxide film stainless steel Ecoli antibacterial rate of more than 99%, Staphylococcus aureus antibacterial rate of more than 92%; (Zhang Xianfeng)
