Round-ball-shaped diatomite light-weight through hole porcelain granule with air purification function

Abstract

The invention discloses a round-ball-shaped diatomite light-weight through hole porcelain granule with an air purification function. The round-ball-shaped diatomite light-weight through hole porcelain granule is mainly characterized by being prepared from ingredients of attapulgite porcelain powder with the air purification function, diatomite, activated clay waste slag, white carbon black, activated aluminum oxide, sodium aluminate, lauryl sodium sulfate, wiping-washable diatomite photocatalyst spray coating liquid and the like. The ingredients are subjected to agitation, extrusion granulation, drying, roasting, heat insulation, sieving, soaking, drying, sieving and sealing packaging to obtain the round-ball-shaped diatomite light-weight through hole porcelain granule with the air purification function. The round-ball-shaped diatomite light-weight through hole porcelain granule with the air purification function has the characteristics of large specific surface area, low piling density, high moisture absorption rate, excellent adsorption performance, good light-weight intensity and micro hole and big hole integration, and is suitable for being used for adsorbing and degrading contaminants such as formaldehyde, ammonia, benzene and TVOCs (total volatile organic compounds) through being put in indoor positions, furniture cabinets, vehicles, airplanes, boats or other buildings so as to achieve the goal of air purification.

Description

technical field [0001] The invention relates to ceramsite, in particular to a spherical diatomite lightweight through-hole ceramsite with the function of purifying air. Background technique [0002] There are several types of air purifiers currently available on the market: adsorption-type air purifiers, masking-type deodorizing products, and decomposing-type deodorizing products. Adsorption-type air purifiers are purification products that use activated carbon, bamboo charcoal, molecular sieves, minerals and other materials to remove pollutants through physical adsorption, chemical adsorption, catalytic oxidation and reduction; masking-type deodorant products use the fragrance of aromatic hydrocarbons to cover the air. In fact, many air fresheners do not remove the odor, but just cover up the odor with a fragrance; decomposing air purification products are relatively rare in the market.

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the above patents are: (1) Diatomite powder, zeolite powder, medical stone powder, tourmaline powder, activated carbon powder and sepiolite powder have not undergone necessary modification treatment, so it is difficult to really play their role in effectively purifying the air

[0005] Spherical air purifiers, molecular sieves, desiccants or other spherical particles available on the market, in the granulation process, the powder ingredients are first processed into a small ball with a diameter of less than 0.5mm, and then the prepared mist The aqueous solution is sprayed into the small balls in the running granulator, and then the powdery ingredients are sprinkled on the surface of the wet pellets. After repeated spraying of the mist aqueous solution and the powdery ingredients are sprinkled on the wet pellets After being wrapped layer by layer, the volume of the pellets continues to increase, and the whole process of granulation is finally completed, and a spherical particle is prepared. Because the internal structure of the spherical particle is very dense, the size of the spherical particle is greatly reduced. The effective specific surface area, the specific gravity and bulk density of spherical particles are relatively large, which directly affects the adsorption and purification effect of spherical particles
