Abstract

The invention discloses an environment-friendly concentrated solution capable of scavenging formaldehyde. The environment-friendly concentrated solution capable comprises, by weight, 25-30 parts of sodium chloride, 5-12 parts of nanometer titania, 6-13 parts of diatom granules, 1-3 parts of chitosan of more than 95% of degree of deacetylation, 12-20 parts of sodium carbonate, 1-3 parts of imidazolidinyl urea, 15-20 parts of traditional Chinese medicine combination and 20-40 parts of high-oxygen water. The environment-friendly concentrated solution capable of scavenging the formaldehyde needs to be diluted during use, and hazardous substances including the formaldehyde, benzene series, sulfur dioxide, carbon monoxide and the like are absorbed through produced oxidizing ability, super-strong free hydroxyl and active oxygen.

Description

technical field [0001] The invention relates to an environment-friendly concentrated liquid for removing formaldehyde. Background technique [0002] Due to air pollution, home decoration, car decoration, etc., people's health is eroded by more and more toxic and harmful gases and tiny particles. For example, after home decoration, harmful gases such as formaldehyde and benzene will remain indoors, or be directly inhaled into the human body , or these substances are adsorbed on PM2.5 particles and enter the human body through the capillaries of the lungs, which is more harmful than pure PM2.5 or pure formaldehyde. [0003] At present, people are constantly devoting themselves to the development of products that adsorb formaldehyde (including organic gases such as benzene), decompose formaldehyde, and remove formaldehyde. Some adsorbents are added to decorative boards, and some adsorbents are padded on various textile fabrics. These application methods can effectively remove ...
