Application of titanium in sterilization
1. The sterilization characteristics of titanium cup
Titanium oxide is an inorganic compound of titanium and oxygen, and is generally used in food additives, paints, cosmetic additives, etc. Titanium oxide is classified into rutile type and anatase type according to its crystal structure. Among them, the anatase type has a sterilizing effect. The titanium oxide film oxidized by the positive electrode has temperature characteristics during chemical synthesis treatment, which makes it a crystal of anatase, which is formed on the surface of titanium.
The surface of the titanium cup is an oxide film, which will not feel the rusty smell of metal products, nor will it cause the beverage to produce a peculiar smell, and you can taste a very refreshing taste.
The mechanism of photobacterial action is that after titanium oxide is exposed to light, positive holes and negative electrons on its surface are released. This energy dissolves with the oxygen contained in the water to form active oxygen, which decomposes the water to produce hydrogen and oxygen. In this process, under the action of hydrogen and active oxygen, it sterilizes and decomposes organic matter. At the same time, it also decomposes bacteria, sourness, etc., which can also make the beverage taste more mellow.
2. Sterilization of titanium air conditioner
Titanium air conditioners are equipped with the third-generation titanium technology, which has the four major functions of dustproof, mildewproof, sterilization and corrosion resistance. It keeps the evaporator condenser clean at all times and keeps every strand of air breathed in the room fresh and clean. At the same time, titanium The evaporator uses a photocatalytic nano-silver-titanium dioxide composite material, which effectively removes smoke and other peculiar smells, and effectively removes the formaldehyde content in the new house. What is more valuable is that as long as the titanium gold is in a light environment, it can be automatically all-weather Sterilization. Only weak light can catalyze sterilization, and the evaporator itself sterilizes, which completely solves the problem of a large number of bacteria and germs in the evaporator and ensures clean and healthy indoor air.
The application of titanium in antibacterial properties-titanium alloy dental implants
With the rapid development of dental implant restoration technology, the development and research of dental implant materials has also increased. Medical titanium and titanium alloy implants can not only form osseointegration with bone (the bone tissue is in direct contact with the surface of the implant, and there is no soft tissue intervention between the two), and implantation into the human body will not cause local or systemic adverse reactions, and no teratogenic, It has sensitization and carcinogenic effects, and has good biocompatibility, mechanical properties and mechanical processing properties. It is currently an ideal dental implant material.
People have long recognized that Cu element has broad-spectrum antibacterial properties. Regarding the antibacterial mechanism of Cu, the latest research shows that the antibacterial properties of Cu-containing alloys are mainly due to the existence of Cu-rich ε-Cu phase in the alloy, which is called the antibacterial phase. Bacteria are not easy to form a protective biofilm on the surface of Cu. Cu can destroy the cell membrane structure of bacteria and cause bacterial apoptosis. Research by Shirai et al. confirmed that the strong antibacterial activity of Ti-Cu (10wt% Cu) alloy against Escherichia coli and Staphylococcus aureus is 99.9%. Ti-Cu alloy uses the antibacterial properties of copper to make it have long-lasting, broad-spectrum antibacterial properties, and the sterilization rate for various bacteria can reach more than 90% or even 100%, which meets the standards set by the China Antibacterial Materials and Products Industry Association. Therefore, based on these advantages, the research on the optimal ratio of Ti-Cu alloy dental implant materials will be a hot spot in the future. 
The antibacterial and bactericidal uses of titanium are far more than these. With the stimulation of people's wisdom, the excellent and noble quality of titanium will be embedded in people's home life, which will not only beautify people's lives, but also purify human living environment.
