Problems solved by technology

Among them, physical adsorption purification is the first generation of air purification technology, which can quickly purify the air, but its adsorption capacity is limited.
When the adsorption capacity reaches its saturation concentration, not only cannot continue to use, but also has the disadvantage of releasing the adsorbed pollutants to pollute the air again, and relying on adsorption to purify the air only temporarily reduces the concentration of pollutants in the space, and does not completely to clear

Abstract

The invention relates to a preparation method for an air purifying filter screen piece. A preparation method with which air purifying screen pieces which are safe in use and wide in application range can be prepared does not exists at present yet. The preparation method is characterized by comprising the following steps that a transition metal oxide as a main purifying material and an inorganic porous material as an auxiliary additive are adopted to prepare air purifying particles; a non-woven fabric serves as a base body, fine fiber with the same non-woven fabric material is selected as filter screen binder, the air purifying particles are bond to the non-woven fabric serving as the base body through the binder, a layer of non-woven fabric with the same base body material is bond to the air purifying particles to serve as a covering piece, and the air purifying filter screen piece is obtained. The air purifying filter screen piece made of the non-woven fabric through the preparation method has the advantages of being high in purifying efficiency, long in service life, safe in use and wide in application range and is suitable for being produced and applied on a large scale.

Description

technical field [0001] The invention relates to a preparation method of an air purification filter sheet, which belongs to the technical field of environmental protection materials. The prepared air purification filter sheet can be applied in multiple fields and can effectively purify air. Background technique [0002] With the development of science and technology today, the resulting air pollution problems are ubiquitous, and a variety of products to deal with air pollution and purify pollutants have also been produced on the market. In multiple spaces that require air purification treatment, different air purification products are required, and for special spaces such as car interiors and outdoor areas where the quality of pollutants is relatively large and the distribution range is uniform, it is difficult to apply large-scale applications that require dynamic operation of power supply Air purification products can only rely on non-powered purification equipment for air ...
