How is the Silica Applied in Antibacterial Material?
By utilizing the special characteristics like large specific surface area, the porous structure, super adsorption capacity of silica, we can develop silica based antibacterial powder with high efficiency, long-lasting, high temperature resistance and broad-spectrum antibacterial. The antibacterial capacity is determined by the concentration of the antibacterial powder.
There are two examples for the antibacterial effects:
1st, adding 0.315% of nano-antibacterial powder in water, the antibacterial ability of Gram-positive representative gram-negative representative strains can be very clearly revealed.
2nd, adding Ag + 0.01mg / 1, we can completely kill the E. coli in water, and can maintain the effect up to 90 days that without reproducing the new flora.
Please see the following applications for Silica based antibacterial materials:
1, silica based antibacterial powder can be applied in enamel glaze or porcelain, with the anti-mildew, antibacterial functions, the antibacterial rate is as high as 99%. And comparing with other antibacterial material, the silica based antibacterial material can still maintain a strong antibacterial performance under conditions like in the alkaline liquid and high temperature (about 900 ℃), which is a the necessary conditions when producing this kind of products.
2, silica based antibacterial powder added to the interior wall paint can create a long-term antibacterial and anti-mildew functions for interior wall paint.
3, silica based antibacterial powder can achieve significant antibacterial performance by applied in women's underwear detergents, wool, cashmere detergent, other detergent, hand sanitizer, the health and epidemic prevention department testing, and so on.
It is foreseeable that with the enhancement of people's health awareness, silica based antibacterial powder will gradually be accepted by the relevant enterprises and emerge in industries such as bills, healthcare, chemical building materials, household appliances, functional fibers and plastic products.
