Gravel-shaped pumice lightweight ceramsite with air purifying function

Abstract

The invention discloses a gravel-shaped pumice lightweight ceramsite with an air purifying function. The technical scheme is characterized in that the ingredients of the ceramsite comprises attapulgite pottery clay powder with an air purifying function, pumice, activated clay waste residue, white carbon black, activated aluminum oxide, sodium aluminate, hollow microbeads, sodium dodecyl sulfate and a scrubbable pumice photocatalyst spraying liquid. The ingredients are stirred, and extruding and granulating, drying, crushing, screening, roasting, heat-preserving, screening, soaking, drying, screening and sealed packaging are conducted to form the gravel-shaped pumice lightweight ceramsite with the air purifying function. The gravel-shaped pumice lightweight ceramsite has the advantages of large specific surface area, low bulk density, good light intensity, high moisture absorption rate and excellent adsorption and purification performance, and is suitable for being placed in rooms, furniture cabinets, vehicles, ships or other buildings for adsorbing and degrading formaldehyde, ammonia, benzene, TVOC and other pollutants to achieve the purpose of purifying the air for a long time.

Description

Technical field [0001] The invention relates to ceramsite, in particular to a crushed pumice light ceramsite with air purifying function. Background technique [0002] There are several types of air purifiers currently available on the market: adsorption-type air purifiers, cover-type deodorant products, and decomposition-type deodorant products. Adsorption-type air purifiers are purification products that use the physical adsorption, chemical adsorption, catalytic oxidation and reduction properties of activated carbon, bamboo charcoal, molecular sieves, minerals and other materials to remove pollutants; masking deodorizing products use aromatic hydrocarbons to cover the air Many air fresheners do not actually remove the odors in the various odors, but only use a fragrance to cover the odors; decomposition-type air purification products are relatively rare on 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
