Spherical wollastonite lightweight hole ceramsite with air purification function

Abstract

The invention discloses a spherical wollastonite lightweight hole ceramsite with an air purification function. According to key points of the technical scheme, the ingredients are composed of attapulgite clay powder with the air purification function, wollastonite, activated white earth residues, white carbon black, activated alumina, sodium aluminate, lauryl sodium sulfate, scrubbing photocatalyst spraying solution and the like. The preparation method comprises the following steps: stirring ingredients, performing extruding granulation, drying, roasting, maintaining the temperature, screening, soaking, drying, screening, sealing, and packaging into the spherical wollastonite lightweight hole ceramsite with the air purification function. The spherical wollastonite lightweight hole ceramsite with the air purification function has the characteristics of large specific surface area, low bulk density, high moisture absorption rate, excellent absorption performance, high lightweight strength and capacity of integrating micro-pores and macropores and is applicable to being placed in rooms, furniture cabinets, vehicles, airplanes, ships or other buildings for adsorbing and degrading formaldehyde, ammonia, benzene, TVOCs (total volatile organic compounds) and other pollutants so as to achieve the aim of purifying air.

Description

technical field [0001] The invention relates to ceramsite, in particular to a spherical wollastonite 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 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
