Problems solved by technology

Activated carbon adsorption technology can only absorb and store harmful substances, but cannot eliminate them eventually, so it is very inconvenient to replace the adsorption materials frequently
The negative ion high-voltage electrostatic technology is a physical process, which can remove smoke and dust in the air, but the removal of indoor formaldehyde pollution is not obvious; secondly, it is expensive, requires electricity when used, and will generate noise, which is not conducive to mass production. popularization

example 1

[0022] After decoration, the concentration of free formaldehyde in indoor wardrobes and wardrobes is high, and the smell is pungent and pungent, causing people to cry and cough. Spray the inner wall of the wardrobe with the product of the present invention. The air formaldehyde concentration in the wardrobe before treatment is 2.5mg / m3, the spraying amount during treatment is 35ml / m3, and the air formaldehyde concentration in the wardrobe after treatment is <0.08mg / m3.

example 2

[0024] Spray the product of the present invention on the two surfaces of two artificial plywoods of 0.5 square meters, put into the airtight test chamber (volume is: 1.5 cubic meters) that has been annotated with 0.74Mg / cubic meter of formaldehyde after treating to dry naturally, divide then The content of formaldehyde in the test cabin was sampled and tested at time intervals. Inspection equipment: QT-2 atmospheric sampler, 722 spectrophotometer; testing conditions: 1.5 cubic meters of test cabin, the test results are as follows:

Abstract

The invention relates to a formaldehyde remover and its preparation method, belonging chemical industry technical field. The formaldehyde remover is prepared from following raw materials through uniformly stirring and mixing according to the weight percentage, including: 50-85% of water; 0-12% of citric acid, 0-3% of ammonium carbonate, 0-15% of ammonium chloride; 2-10% of ammonium acetate and 3-10% of urea. The formaldehyde remover is mainly used for reducing the release amount of formaldehyde in the artificial plate, removing the formaldehyde pollution after interior decoration and protecting people body health. After spraying 35ml formaldehyde remover in each cubic meter air, the free formaldehyde concentration is lower than 0.08mg / cm3 in the indoor air, thereby the free formaldehyde content in the indoor air reaches national standard.

Description

technical field [0001] The invention relates to a formaldehyde remover and a preparation method thereof, belonging to the technical field of chemical industry. Background technique [0002] In recent years, a large number of wood-based panels have been used in interior decoration, and the accompanying indoor formaldehyde pollution has always been a concern. It is the main cause of cancer, respiratory diseases, leukemia, decreased immunity, fetal teratogenicity, etc., seriously affecting the physical and mental health and normal life of the people. Therefore, purifying indoor air has become a top priority. At present, the methods used in China to purify indoor air include activated carbon adsorption technology, negative ion high-voltage electrostatic dust removal technology, etc. Activated carbon adsorption technology can only adsorb and store harmful substances, but cannot eliminate them eventually. Therefore, it is very inconvenient to frequently replace the adsorption ma...
