Application of Mingzhi Titanium ultrafine monodisperse nanometer titanium dioxide in the field of impregnated paper

1. Product overview

The ultra-fine monodisperse nano TiO2 powder, the crystal phase is anatase phase, the particle size is 3-5 nm, and the appearance is white powder. Add water to quickly form a light blue colloidal dispersion, long-term stability without stratification; The photocatalytic efficiency is 10 times that of the competition product, which is used to decompose formaldehyde, benzene, TVOC and other air pollutants, with excellent sterilization and self-cleaning effect. Third party agencies identified this product as safe, non-toxic, can be used with confidence.

2. Use method

Nanometer titanium dioxide powder was mixed with pure water (deionized water or distilled water) to prepare a photocatalytic liquid with a mass fraction of about 5%.

After that, the photocatalyst solution is mixed with the amino resin (mixture of melamine formaldehyde resin and urea formaldehyde resin) in accordance with the ratio of about 1:9 to form the photocatalyst-amino resin adhesive.

After that, the paper such as plain color base paper or printing decoration paper that needs to be treated is impregnated in the photocatalyst-amino resin adhesive and dried to a certain extent, and the photocatalyst-impregnated paper is formed by hot pressing, or the photocatalyst-impregnated sheet is formed by gluing with the wood-based board substrate.

Note: According to the needs of customers, the concentration, pH value and dosage ratio of the above-mentioned photocatalyst liquid can be adjusted in this process to obtain the effect desired by customers.

Nano titanium dioxide spread on the surface of ceramic tile is compact and flat, high activity, transparent, does not produce white spots, excellent performance

3. Application results

(1) It can effectively kill the bacteria on the surface of the material (E. coli, Staphylococcus aureus, mold and other microorganisms), and play a long-term antibacterial and mildew prevention effect.

(2) With anti-fouling, self-cleaning effect, can be adsorbed on the surface of the colored matter, oil dirt oxidation decomposition.

(3) It has the effect of removing formaldehyde and odor, and can decompose formaldehyde, benzene, TVOC, and odor in the air.

(4) Indoor, hospital, exterior wall and other fields, for bacteria, mold, formaldehyde, self-cleaning, etc.
