Cylindrical light red-mud ceramsite with air purification function and through holes

Abstract

The invention discloses cylindrical light red-mud ceramsite with an air purification function and through holes. The technical scheme mainly includes that ingredients for the cylindrical light red-mud ceramsite include attapulgite pottery clay powder with an air purification function, red mud, activated argil waste residues, white carbon black, activated aluminum oxide, sodium aluminate, hollow micro-spheres, sodium dodecyl sulfate, attapulgite photocatalyst spray liquid capable of being scrubbed and the like; the ingredients are subjected to stirring, extrusion granulation, drying, calcination, heat-insulation treatment, sieving, soaking, drying, sieving and hermetic packaging to obtain the cylindrical light red-mud ceramsite with the air purification function and the through holes. The cylindrical light red-mud ceramsite with the air purification function and the through holes has the advantages of large specific surface area, low stacking density, high moisture absorption, excellent adsorption performance, good lightweight strength and micropore and macropore integration. Besides, the cylindrical light red-mud ceramsite is suitable to be arranged in indoor environments, furniture and cupboards, vehicles, aircrafts, ships or other buildings, pollutants such as formaldehyde, ammonia, benzene and TVOC (total volatile organic compounds) can be adsorbed and degraded by the cylindrical light red-mud ceramsite, and accordingly the purpose of purifying air can be achieved.

Description

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

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
