Problems solved by technology

Formaldehyde in life not only exists in the air (formaldehyde is very soluble in water), so the moisture in the air humidity also contains a considerable part of formaldehyde, and the moisture absorption power of activated carbon is very weak, so the adsorption of formaldehyde in the overall environment is limited. very obvious limitations

Abstract

The invention discloses a composite powder with an efficient adsorption effect. The composite powder comprises the following raw materials in parts by weight: 50-60 parts of attapulgite, 10-20 parts of diatomite, 25-30 parts of rice hull powder, 4-10 parts of ethyl orthosilicate, 2-3 parts of absolute ethanol, 4-5 parts of 25% ammonia water, 0.4-1 part of sodium potassium silicate, 0.1-0.2 part of ammonium ferrous sulfate, 0.5-1 part of metaboric acid, 80-100 parts of de-ionized water and 1-2 parts of ammonium zirconium carbonate. The powder is strong in adsorption power, can be used for effectively adsorbing formaldehyde in air, is natural, nontoxic, odor-free and good in environmental protection property, and is a natural environment-friendly product; no harmful chemical substances are volatilized, and the body health of users cannot be harmed.

Description

technical field [0001] The invention mainly relates to the field of adsorbents, in particular to a composite powder with high-efficiency adsorption effect. Background technique [0002] Most of the formaldehyde adsorbents currently on the market are based on activated carbon. Formaldehyde in life not only exists in the air (formaldehyde is very soluble in water), so the moisture in the air humidity also contains a considerable part of formaldehyde, and the moisture absorption power of activated carbon is very weak, so the adsorption of formaldehyde in the overall environment is limited. Very obvious limitations. Contents of the invention [0003] The object of the present invention is to provide a composite powder with high-efficiency adsorption effect. [0004] The present invention is achieved through the following technical solutions: [0005] A kind of composite powder with efficient adsorption effect is characterized in that it is made up of the following r...
