Abstract

The invention discloses a novel harmful gas adsorbing particle, and a preparation method thereof. The novel harmful gas adsorbing particle comprises, by weight, 100 parts of calcium silicate powder, 0.5 to 3 parts of a photocatalysis nanometer powder material, 2 to 20 parts of a modifying agent, 5 to 20 parts of a coagulant, and 3 to 8 parts of a wetting agent. The preparation method comprises following steps: the raw materials are added successively, and an obtained mixture is subjected to granulation, screening, and drying. The novel harmful gas adsorbing particle is capable of maintaining the porous performance of microcellular calcium silicate, is fine in pore structure development, large in specific surface area, excellent in nanometer performance, and high in absorption capacity; the high porosity structure and the nanometer sheep structure are capable of improving the absorption capacity, and excellent absorption effect onaldehydes, benzenes, and a plurality of harmful gas are achieved.

Description

technical field [0001] The invention relates to the technical field of adsorbents, in particular to a novel harmful gas adsorption particle and a preparation method thereof. Background technique [0002] In recent years, with the continuous enhancement of people's awareness of environmental protection, various harmful gas pollution closely related to daily production and life has attracted more and more attention, such as formaldehyde, glyoxal, benzene compounds and VOC produced by industrial production. In order to meet people's needs for eliminating various harmful gases, there are many kinds of gas adsorbents on the market. Although these products have certain adsorption effects on various harmful gases, in general, most of the products have strong selectivity for gas adsorption. , can only deal with certain harmful gases, not broad-spectrum. Therefore, it is imperative to develop efficient and broad-spectrum multifunctional harmful gas adsorption materials, which have b...
