Problems solved by technology

[0003] After the existing photocatalyst filter has been used for a period of time, dust will remain on it. When the dust is removed, the photocatalytic nano-scale titanium dioxide will be separated from the filter matrix with the dust, resulting in a decrease in catalytic efficiency and affecting use.

Abstract

The invention relates to the field of photocatalyst filter screens, in particular to a photocatalyst filter screen and a processing method thereof. The photocatalyst filter screen in which photocatalytic nanoscale titanium dioxide is stably combined with a filter screen substrate can be produced, so that the catalytic efficiency is kept after dust is removed. The method comprises the following steps: step 1, a filter screen base material is prepared; 2, the filter screen base material is cleaned through a detergent, and grease, dust and other impurities are removed; 3, the cleaned filter screen base material is cleaned again with clear water, and residues of the detergent are removed; 4, the filter screen base material is dried; 5, the filter screen base material is coated with an adhesive; and 6, photocatalytic nanoscale titanium dioxide powder is evenly sprayed to the filter screen coated with a bonding layer through a spraying device, curing forming is conducted, and the photocatalyst filter screen is obtained. A filter screen base body in the photocatalyst filter screen is firmly combined with the photocatalytic nano-scale titanium dioxide powder.

Description

technical field [0001] The invention relates to the field of photocatalyst filter screens, in particular to a photocatalyst filter screen and a processing method thereof. Background technique [0002] Photocatalyst is a general term for a photo-semiconductor material with photocatalytic function represented by nano-scale titanium dioxide. It is coated on the surface of the substrate and has a strong catalytic degradation function under the action of ultraviolet light and visible light: it can effectively degrade air. Toxic and harmful gases, can effectively kill a variety of bacteria, and can decompose and harmless the toxins released by bacteria or fungi, and also have the functions of removing formaldehyde, deodorizing, anti-pollution, and purifying air. [0003] After the existing photocatalyst filter has been used for a period of time, dust will remain on it. When the dust is removed, the photocatalytic nano-scale titanium dioxide will separate from the filter matrix alo...
