Crushed stone-type alumina light ceramsite with air purifying function

Abstract

The invention discloses a crushed stone-type alumina light ceramsite with an air purifying function. Ingredients of the ceramsite comprise attapulgite clay powder with an air purifying function, alumina, activated carclazyte residues, white carbon black, sodium aluminate, hollow beads, calcined gypsum powder, sodium dodecyl sulfate and a scrubable alumina photocatalyst spray liquid. Through ingredient stirring, extruded granulation, drying, crushing, screening, roasting, thermal insulation, screening, immersion, drying, screening and sealed packaging, the crushed stone-type alumina light ceramsites with an air purifying function are obtained. The crushed stone-type alumina light ceramsite with an air purifying function has a specific surface area, low bulk density, light weight, high strength, high moisture absorption and excellent adsorption and purification performances, is suitable for being used in a room, a furniture cabinet, a vehicle, a ship or other buildings, has effects of adsorption and degradation of pollutants such as formaldehyde, ammonia, benzene and TVOC and realizes the purpose of purifying the air for a long time.

Description

technical field [0001] The invention relates to ceramsite, in particular to a crushed stone-shaped aluminum oxide lightweight 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
