Abstract

A window screen based on electrostatic adsorption and photocatalyst belongs to the technical field of building materials. It includes a gauze, which is characterized in that it is provided with a drive plate, and the gauze has three layers: an outer layer of conductive gauze, an intermediate insulating gauze, an inner layer of conductive gauze, the outer layer of conductive gauze, the inner layer of conductive gauze The net is respectively connected with the positive pole and the negative pole of the driving board through the connector, and the surface of the intermediate insulating gauze is coated with nanometer photocatalyst. The invention improves the ability of the window screen to sterilize, disinfect and remove organic pollutants in the air. The invention belongs to a healthy and environment-friendly window screen in the field of building materials, and the market demand is huge. At the same time, specific technical parameters and production processes have been proposed in the present invention, which has high operability. Therefore, the economic benefit after the industrialization of the present invention is very considerable.

Description

technical field [0001] The invention relates to a healthy and environment-friendly window screen, in particular to a window screen based on electrostatic adsorption and photocatalyst, and belongs to the technical field of building materials. Background technique [0002] The current window screens only have the function of preventing mosquitoes, and some window screens with large meshes cannot even block the invasion of small mosquitoes. The patent name is photocatalyst window screen (the applicant is Chen Limin, the application date is March 21, 2005, and the announcement number is CN2775271Y). It aims to improve the bactericidal performance of window screen, but due to the technical problems of photocatalyst, no related products have been put into the market so far. And there is no similar product at present to have the multifunctional window screen of efficient dust removal, sterilization, disinfection and blocking mosquito invasion. Contents of the invention [0003] ...
