preparation example Construction

[0056] The present invention also provides a kind of preparation method of above-mentioned supported activated carbon, and this method comprises the following steps:

[0057] (1) The activated carbon carrier is loaded with a water-soluble inorganic base and a bactericide to obtain activated carbon loaded with a bactericide.

[0058] Preferably, the water-soluble inorganic base and the fungicide are dissolved in water, the activated carbon carrier is added, after impregnated, dried to obtain the activated carbon loaded with the fungicide.

[0059] Wherein, the mass ratio of water-soluble inorganic base to water is 1-10%, preferably 2-8%, most preferably 3-7%; the mass ratio of fungicide to water is 5-20%, preferably 5-16% %, most preferably 8-13%; the water-soluble inorganic base and bactericide in the mass ratio can make the activated carbon carrier load a sufficient load.

[0060] When the load of the fungicide on the activated carbon is low, it will affect the killing effec...

Embodiment 1

[0079] Prepare 200 g of a mixed solution of sodium hydroxide and polyhexamethylene biguanide hydrochloride, wherein the mass ratio of sodium hydroxide is 5%, and the mass ratio of polyhexamethylene biguanide hydrochloride is 10.5%.

[0080] Weigh 100 grams of raw carbon with a carbon tetrachloride adsorption rate of 100%, immerse the raw carbon in the mixed solution for 1 hour, take it out after the immersion is completed, and dry it at 130 ° C for 3 hours to obtain 120.5 grams of product.

[0081] Through testing, the product is loaded with 4.1% sodium hydroxide, 10.1% loaded polyhexamethylene biguanide hydrochloride, and 6.3% water content.

Embodiment 2

[0083] Prepare 200 g of a mixed solution of sodium hydroxide and polyhexamethylene biguanide hydrochloride, wherein the mass ratio of sodium hydroxide is 7%, and the mass ratio of polyhexamethylene biguanide hydrochloride is 12%.

[0084] Weigh 150 grams of raw carbon with a carbon tetrachloride adsorption rate of 70%, soak the raw carbon in the mixed solution for 2 hours, take it out after the immersion is completed, and dry it at 150° C. for 3 hours to obtain 173 grams of product.

[0085] Through testing, the product is loaded with 5.9% sodium hydroxide, 12.9% loaded polyhexamethylene biguanide hydrochloride, and 4.7% water content.

Abstract

The invention provides a loaded activated carbon with indoor formaldehyde removal and sterilizing and anti-mildew functions. The loaded activated carbon includes an activated carbon carrier, a water-soluble inorganic base, a bactericide and moisture. Optionally, the loaded activated carbon also includes a loaded activated carbon. 0‑1% fungicidal substance by mass of activated carbon. The loaded activated carbon provided by the invention is loaded with water-soluble inorganic alkali, bactericide and water, can capture low-concentration formaldehyde in the air through chemical reaction, has a good effect on indoor formaldehyde removal, and improves indoor air quality.

Description

technical field [0001] The invention relates to an activated carbon, in particular to a loaded activated carbon with the functions of indoor formaldehyde removal, sterilization and mildew prevention. Background technique [0002] As we all know, formaldehyde is a common indoor carcinogen. Many published papers have reported the harm of formaldehyde to people and the current situation of domestic indoor formaldehyde pollution. Indoor formaldehyde has a huge potential harm to human health. [0003] There are many ways to deal with formaldehyde. For example, biological methods. In the paper "Study on the Response of Several Indoor Plants to the Combined Pollution of Benzene and Formaldehyde", Sansevieria Phnom Penh, Aloe Vera, Chlorophytum Chlorophytum, Golden Pueraria, Adiantum and Bird's Nest Responses of ferns and other plants to benzene and formaldehyde pollution. Biological formaldehyde removal can be accepted by most people, and it can beautify the environment with certa...
