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 1.8mg / m3, the spraying amount during treatment is 30ml / m3, and the air formaldehyde concentration in the wardrobe after treatment is <0.08mg / m3.

Abstract
A formaldehyde capture for eliminating the free formaldehyde in air and decreasing the release of formaldehyde from artificial board is prepared from water, ammonium acetate, urea, sodium carbonate, sodium chloride, ammonium chloride and ammonium carbonate through proportional mixing.
Description
technical field [0001] The invention relates to a formaldehyde scavenger and a preparation method thereof, belonging to the technical field of chemical industry. Background technique [0002] In recent years, with the increase in the number of wood-based panels used in decoration, the accompanying indoor formaldehyde pollution has always been a concern. There is often a pungent smell coming out of newly renovated houses and wardrobe cabinets. This is the poisonous gas - formaldehyde. When formaldehyde reaches a certain concentration, it will irritate the upper respiratory tract and cornea of the human body. Long-term exposure will reduce the body's immunity, especially for the elderly, children and pregnant women. It will cause infertility in pregnant women and deformities in newborns. Therefore, purifying indoor air and reducing indoor formaldehyde pollution has become a top priority. At present, the methods used in China to purify air include activated carbon adsorptio...
