Gravel-shaped sepiolite lightweight ceramsite with air purifying function

Abstract

The invention discloses a gravel-shaped sepiolite lightweight ceramsite with an air purifying function. According to main points of a technical scheme of the invention, the gravel-shaped sepiolite lightweight ceramsite comprises the following ingredients: attapulgite pottery clay powder with the air purifying function, sepiolite clay, waste active white clay residue, lightweight magnesium oxide, hollow microspheres, calcined gypsum powder, sodium dodecyl sulfate, a scrubbable sepiolite photocatalysis spray liquid, etc. The gravel-shaped sepiolite lightweight ceramsite is prepared through the following steps: subjecting the ingredients to stirring, and carrying out extruding granulation, drying, crushing, screening, calcination, heat preservation, screening, soaking, drying, screening and seal packaging so as to obtain the gravel-shaped sepiolite lightweight ceramsite with the air purifying function. The gravel-shaped sepiolite lightweight ceramsite with the air purifying function has the characteristics of large specific surface area, low bulk density, good lightweight intensity, high moisture absorption rate and excellent adsorption and purification performances, is applicable to placement in houses, furniture, cabinets, vehicles, ships or buildings, and can adsorb and degrade pollutants like formaldehyde, ammonia, benzene and TVOC, thereby achieving the purpose of purifying air for a long time.

Description

technical field [0001] The invention relates to ceramsite, in particular to a gravel-shaped sepiolite light 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
