Where Is The Indoor Formaldehyde Coming From?
Sep 14, 2018

Studies at the University of Yokohama in Japan have shown that toxic and harmful gases such as formaldehyde and benzene can be released for 3 to 15 years. According to reports in the literature, Lu Zhixin, from the Jining City Center for Disease Control and Prevention in Shandong Province, found that the rate of formaldehyde in the air after 3 years of room decoration was still 7.55%, which was at a high level.


So where do these formaldehydes come from? Should we do this again?
 
One is artificial wood panels such as plywood, blockboard, medium density fiberboard and particleboard used for interior decoration. Because formaldehyde has strong adhesiveness and also has the function of strengthening the hardness and anti-insect and anti-corrosion of the board, the adhesive used in the production of wood-based panels is urea-formaldehyde resin with formaldehyde as the main component;
 
The second is furniture made of wood-based panels. A comparative test conducted by a consumer association in a city showed that among the 60 sets of medium-density furniture samples extracted, 29 sets of formaldehyde exceeded the relevant national standards, and the over-standard rate was as high as 48.23%;
 
The third is other decorative materials containing formaldehyde, such as white latex, foam, paint and paint. Experts specially reminded that latex adhesives are widely used in wood decoration and wall treatment in decoration and decoration, especially formaldehyde in the latex sealed on the wall is difficult to remove;
 
The fourth is interior decorative textiles, including bedding, wall coverings, wallpaper, chemical fiber carpets, curtains and fabric furniture. In textile production, in order to increase the anti-wrinkle performance, waterproof performance, fire resistance, often add some formaldehyde-containing additives.
