Method for eliminating volatile organic compounds such as formaldehyde and benzene in furniture

Abstract

The invention relates to a method for eliminating volatile organic compounds such as formaldehyde and benzene in furniture; strippers which are respectively sprayed on all surfaces of furniture platepieces which are machined, assembly parts which are sprayed with paint, leathers before being assembled, textile fiber material, plastics, foaming fillers and the like after being pulverized, and thefurniture plate pieces, the assembly parts, the leathers, the textile fiber material, the plastics, the foaming fillers and the like are separately placed and are naturally dried for more than twentyfour hours, and then are assembled after being qualified by detection; the strippers are extracted from tree branches, stems, flower and fruits; after being treated, the removal rate of residual organic compounds in the furniture is high, and the removal rate of formaldehyde can reach more than 95 percent, and the removal rate of benzene and derivatives thereof is more than 93 percent and the removal rate of total volatile organic compounds (TVOC) can reach more than 98 percent; the safety is good, the pertinence is strong without causing secondary pollution of the furniture and environment.

Description

technical field [0001] The invention relates to a method for eliminating volatile organic compounds such as formaldehyde and benzene in furniture. Background technique [0002] With the continuous improvement of people's living standards and the strengthening of health and environmental awareness, people have higher and higher requirements for the residual harmful substances in furniture, and a large number of plywood, blockboard, medium density fiberboard, high Density fiberboard, particle board and other wood-based panels, and these panels need to use urea-formaldehyde resin-based adhesives during the production process, and the residual or non-reactive formaldehyde in the panels will gradually be released to the surrounding environment; at the same time, furniture is connected, fixed and assembled. Adhesives are generally used in the process, and this bonding process leaves at least low-boiling volatile VOC substances such as benzene, xylene, and formaldehyde; , acrylic,...

AI Technical Summary

Problems solved by technology

At present, the existing elimination methods generally adopt physical adsorption technology such as activated carbon adsorption and chemical adsorption neutralization technology. It reacts to destroy the molecular structure of harmful gases such as formaldehyde and benzene, so as to reduce the concentration of formaldehyde. The disadvantage of using this type of product is that the effect is limited by saturation. Generally, it must be used multiple times and cannot be used on paint surfaces, leather materials, and textiles. It can be used directly on fiber, plastic, foam filler, etc., and it is easy to cause secondary pollution if the control is not good
