In the production of kitchen equipment, medical equipment, toiletries and cleaning the renovation, people have been looking forward to not only antibacterial but also the shape of metal new materials.
Both structural and functional properties of new materials - both antibacterial stainless steel mechanical properties of structural materials, but also the physical, chemical and other properties of functional materials, like stainless steel, as have the role of decoration and landscaping as a component, while There are antibacterial, sterilization self-cleaning effect.
Data indicate that the now widely used antibacterial agent, is the two types of organic antibacterial agent and the inorganic antimicrobial agent. Organic antimicrobial agent has a long history, has been widely applied in the medical field, spraying or dipping. But they are insufficient in security World Steel Pipe News , persistent, broad-spectrum antimicrobial resistance, heat resistance, especially in serious harm to humans and the environment can not be used on many occasions. Inorganic antimicrobial agent as an additive, made of the antibacterial effect of cloth, plastic products, activated carbon, sanitary ceramics, etc., the use of the increasingly widespread. On a heat resistance, wear resistance, corrosion resistance, strength and formability, can not meet many everyday needs. Therefore, in the manufacture of kitchen machinery world pie network information , medical equipment, toiletries and cleaning and decoration, you must use the antibacterial effect and shapes, beautiful appearance of metal products. This new birth of the antibacterial effect of stainless steel, is undoubtedly the ideal product for people's minds.
Antibacterial stainless steel antibacterial activity generated is divided into two kinds: the coating type and antimicrobial type. Former can transform the existing stainless steel products, stainless steel plated with a bactericidal metal material, or other bactericidal effect of inorganic materials, but the drawback is easy to wear, easy to aging, with the temperature difference and the external environment changes change, so that the stainless steel loss of antibacterial activity; the latter is to add some antibacterial effect of the metal elements in stainless steel production process, through the special treatment to the stainless steel itself, produce antimicrobial, it does not have the shortcomings of the former, and low cost, easy process.
E. coli kill rate of 99.9%, 99.5% of the killing rate of Staphylococcus aureus, Candida albicans killing rate of 99.0%, 86.6% of the Kuhei bacteria kill rate. Common sense tells us that these four kinds of bacteria are the most common of ordinary life, able to achieve the killing effect to prove that a broad-spectrum antibacterial activity of antibacterial stainless steel.
With the adjustment and optimization of material composition and microstructure, the antibacterial effect will be further improved. In aqueous solution, antibacterial / antimicrobial test, the antibacterial stainless steel specimens immersed in the preparation of a good bacteria, after different times of immersion, the number of colonies observed in bacteria. The results showed that E. coli and Staphylococcus aureus kill rate of 90% -95%, indicating that the material in aqueous solution can also kill the bacteria. That is, not only can kill the bacteria in direct contact, indirect contact through the diffusion of the solution to kill bacteria.
Materials field for the "sterilization" and "antimicrobial" not clearly defined. Generally antibacterial understand the order to inhibit bacterial growth, growth and reproduction, sterilization is to kill microbes. Antibacterial stainless steel can not breeding bacteria attached on it, kill or inhibition in the bacteria count low level state, but does not alter the strength of ordinary stainless steel, corrosion resistance, aesthetic characteristics, with a very broad application prospects. Look forward into the people.
