Titanium oxide exhibits antibacterial properties based on photocatalytic reactions that decompose organic substances.
Its first characteristic is immediacy. While the effects of silver-based antibacterial agents take approximately 24 hours, titanium oxide requires only about 1 hour.
The second feature is that titanium oxide is a semi-permanent antibacterial agent. Unlike other antibacterial agents, its efficacy doesn't gradually decline as the antibacterial components dissolve.
The third characteristic is its excellent safety profile. It can be used in food additives without affecting human health upon skin contact.
Additionally, prolonging the oxidation process time (e.g., 6 hours) can enhance the photocatalytic activity of oxidized titanium surfaces. Researchers at Kobe Steel in Japan first subjected titanium material to anodic oxidation treatment, followed by applying well-crystallized rutile-type titanium oxide powder, resulting in the development of highly durable antibacterial titanium named "SPARKT." This product exhibits antibacterial properties against E. coli O-157 and MRSA bacteria. Furthermore, it possesses features such as odor resistance and stain resistance, making it suitable for interior and exterior building materials, cookware, tableware, sanitary ware, and various other applications.
the application of titanium in sterilization
Sterilization Characteristics of Titanium Cups
Titanium dioxide is an inorganic compound formed after the oxidation of titanium. The anodic oxidation of titanium generates titanium oxide thin films with temperature-dependent properties. These properties allow it to crystallize into rutile on the surface of titanium.
The surface of titanium cups is covered with a layer of oxide film. This film prevents the metallic taste associated with iron rust and does not impart any peculiar taste to beverages. As a result, one can enjoy beverages in titanium cups without experiencing any metallic or strange aftertaste, allowing for a refreshing taste experience.
The Three Unique Characteristics of Titanium Pots
Affinity with Human Body: Titanium possesses unique biocompatibility. Titanium ions do not transfer within the human body along with blood or bodily fluids. Using titanium cookware would be the ultimate choice for kitchens worldwide.
Sterilization and Bacteriostasis: The surface of titanium cookware remains free from bacterial residue, ensuring a hygienic and clean environment. Storing food in titanium utensils, even overnight dishes, retains their original taste. It truly promotes healthy eating and offers peace of mind.
Non-Harmful Metal: Titanium is a biologically safe metal. Foods cooked in titanium pots do not retain a metallic taste, and titanium ions can even enhance the body's immune system.
Sterilization effectiveness of titanium-gold air conditioning
The titanium-gold air conditioner offers four major benefits: dust resistance, mold resistance, sterilization, and corrosion resistance. Notably, the titanium-gold unit performs automatic sterilization round-the-clock as long as there is ambient light. This effectively resolves the issue of bacterial and pathogenic accumulation on the evaporator, ensuring clean and healthy indoor air.
Titanium in Antibacterial Properties: Titanium Alloy Dental Implants
Medical titanium and titanium alloys for implants not only promote bone formation and osseointegration, but also do not cause adverse local or systemic reactions upon insertion into the human body. These materials have no teratogenic, allergenic, or carcinogenic side effects and possess excellent biocompatibility, mechanical properties, and machining capabilities, making them an ideal choice for dental implants.
The antibacterial and bactericidal applications of titanium extend beyond dental implants. As human intelligence drives innovation, the exceptional and noble qualities of titanium will be reflected in various aspects of our lives. Titanium not only enhances human life but also serves as the "green metal" in purifying the living environment.
