Problems solved by technology

[0003] At present, physical adsorption and other methods are mainly used to remove formaldehyde. Commonly used adsorbents include activated carbon, bamboo charcoal, etc., which have low cost and wide application range, but the adsorption capacity is limited, the efficiency of formaldehyde removal is low, and often needs to be replaced, causing secondary pollution

Abstract

The invention provides a formaldehyde adsorbent, which comprises the following components in parts by weight: 100 parts of activated carbon, 10-30 parts of nano hollow spheres and 10-30 parts of a formaldehyde remover. According to the technical scheme, the nano hollow spheres and the formaldehyde scavenger are mixed into the activated carbon, the formaldehyde adsorption burden of the activated carbon is relieved in a physical adsorption and chemical degradation mode, so that the problems that the activated carbon is limited in adsorption capacity and prone to saturation are effectively solved, and therefore the formaldehyde removal efficiency of the adsorbent can be improved and better formaldehyde treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of formaldehyde treatment, in particular to a formaldehyde adsorbent. Background technique [0002] Formaldehyde is one of the most common indoor air pollutants. This harmful gas mainly comes from indoor furniture, wood veneer, paint, wallpaper, wall covering, carpet and other decorative materials. Low concentration of formaldehyde can easily lead to chronic respiratory diseases, neonatal Physical decline, pregnancy syndrome, and even cancer may be caused. High concentrations of formaldehyde are even more harmful to the human nervous system, immune system and liver. [0003] At present, physical adsorption and other methods are mainly used to remove formaldehyde. Commonly used adsorbents include activated carbon, bamboo charcoal, etc., which are low in cost and have a wide range of applications, but the adsorption capacity is limited, the efficiency of formaldehyde removal is low, and they often need to be r...
