Cylindrical chlorite-montmorillonite-mixed-layer-clay lightweight through-hole haydite with air purifying function

Abstract

The invention discloses cylindrical chlorite-montmorillonite-mixed-layer-clay lightweight through-hole haydite with an air purifying function. The key point of the technical scheme of the invention is as follows: the haydite is prepared from the ingredients, i.e., attapulgite clay powder with an air purifying function, chlorite-montmorillonite mixed-layer clay, activated clay waste residues, white carbon black, activated alumina, sodium aluminate, hollow microspheres, dried gypsum powder, sodium lauryl sulfate, scrubbed chlorite-montmorillonite mixed-layer clay photocatalyst spraying fluid. The cylindrical chlorite-montmorillonite-mixed-layer-clay lightweight through-hole haydite with the air purifying function is prepared through carrying out stirring on the ingredients, carrying out extruding and granulating, carrying out baking, carrying out roasting, carrying out heat preservation, carrying out screening, carrying out soaking, carrying out baking, carrying out screening, and then, carrying out sealed packaging. The haydite has the characteristics of large specific surface area, low bulk density, high moisture absorption, superior adsorption performance, good lightweight strength and integrated micropores and macropores and is suitable for being placed in rooms, furniture cupboards, vehicles, airplanes, ships or other buildings so as to adsorb and degrade pollutants such as formaldehyde, ammonia, benzene and TVOC, and thus the aim of purifying air is achieved.

Description

technical field [0001] The invention relates to ceramsite, in particular to a cylindrical green smudged layer clay light-weight 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, covering-type deodorizing products and decomposing deodorizing 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; cover-type deodorant products use the aroma of aromatic hydrocarbons to cover the air. In fact, many air fresheners do not remove the odor, but only cover the odor with a fragrance type; 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
