Cylindrical lightweight kaolin through-hole ceramsite with air purification function

Abstract

The invention discloses cylindrical lightweight kaolin through-hole ceramsite with an air purification function. According to the technical scheme, ingredients comprise attapulgite pottery clay powder with the air purification function, kaolin, activated argil residues, white carbon black, activated alumina, sodium aluminate, sodium dodecyl sulfate, a scrubbed kaolin photocatalyst spray coating solution and the like. The cylindrical lightweight kaolin through-hole ceramsite with the air purification function is obtained by performing stirring, extrusion granulation, drying, roasting, heat preservation, screening, impregnation, drying, screening and sealing packaging on the ingredients. The cylindrical lightweight kaolin through-hole ceramsite with the air purification function has the characteristics of large specific surface area, low bulk density, high moisture absorption, high adsorption performance, lightweight, strong strength and integration of micropores and a macropore, and is applicable to adsorption and degradation of pollutants such as formaldehyde, ammonia, benzene and TVOC for fulfillment of the aim of air purification in a room, a cupboard, a vehicle, an airplane, a ship or another building.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cylindrical kaolin light 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.

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 ingredie
