Product Description of SiO2 nanopowder:
Grain Size: 20-30nm
Purity: 99.8%
Type: hydrophilic, hydrophobic
Color: white
Grade: industrial
Features and Performance in antiacterial field of Silica nanopowder: Based on the large specific surface area, surface mesoporous structure and superabsorbent capacity of nano Si02 powders, and the singular physical and chemical properties, the functional ions such as silver ions were uniformly designed into the mesoporous surface of nano Si02, and stable and successfully developed Efficient, durable, high temperature, broad-spectrum antibacterial nano-antibacterial powder.After testing, when the concentration of nano-antibacterial powder in water is only 0.315%, the gram-positive representative of the bacteria and Gram-negative bacteria on behalf of the bacteria can be very obvious that the antibacterial ring appears 2- 3mm, and with the nano-antibacterial powder in the water concentration increases, significantly inhibited the inhibition zone. According to the determination of water containing Ag + 0.01mg / 1, you can completely kill the water in E. coli, and can maintain up to 90 days without breeding new flora.Nano antibacterial powder will be used in enamel glaze, to produce a mold, antibacterial function of the drum washing machine, the antibacterial rate of up to 99% or more.Will be added nano-antibacterial powder in the interior wall paint, to produce a long-term anti-bacterial anti-mildew function of the interior wall paint. The use of nano-antibacterial powder in women's underwear detergent, wool, cashmere detergent, detergent, hand sanitizer, the health and epidemic prevention departments, its antibacterial performance is very significant.
