Formaldehyde doors frequency is now zero formaldehyde furniture industry whether reality?

Furniture possession of formaldehyde, costs are tricky
Home decoration, plywood and their products, adhesives, interior paint, wood furniture, wallpaper, Qiangbu Pihui with 107 glue, 804 glue, plywood and flooring with purpose adhesive, foam, paint, etc. are likely presence of formaldehyde and volatile out. However, these materials release formaldehyde, with ordinary wood-based panels used for home improvements, its formaldehyde emission dwarfed. Ordinary wood-based panels fundamental reason for the sustained release of formaldehyde, wood-based panel manufacturing process requires the use of aldehydes adhesives, such as urea-formaldehyde resin. The adhesive itself is directly formaldehyde and urea compounds. Because of the low price, good bonding effect, so a lot of use in the manufacturing process of wood-based panels. Such colloidal biggest drawback is that under natural conditions will continue to spontaneous decomposition restore, re-release of the free formaldehyde. And in the hot and humid environment, such decomposition, deliquescence reaction rate will double.

The Shanghai Furniture Industry Association Secretary-General Xu Guan Rong told reporters: "furniture excessive levels of formaldehyde, mainly due to the machining process, once the plates, glue, paint, formaldehyde content can not be guaranteed, the formaldehyde content of the furniture will not consciously excessive. in order to reduce costs, companies buy the inferior plate. environmentally friendly materials formaldehyde content is low, but the cost is relatively high, and low-grade sheet, the difference of each block in the range of 60-100 yuan. "According to the reporter, the most important raw material in the sheet metal furniture sub-plate, particleboard, MDF and other varieties, are generally bonded by glue made itself contains a certain amount of formaldehyde. Sheet in line with national standards E0, E1, E2 three kinds, where E0 is the most environmentally friendly, lowest formaldehyde content, of course, cost is the highest.
 
Currently, in accordance with state regulations, the furniture formaldehyde emission should be less than 0.15mg/m3. Xu Guanrong "Sometimes manufacturers purchasing more environmentally friendly E0, E1 sheet, but in the process, because the glue, paint, and other factors can also cause high levels of formaldehyde, the Shanghai Committee Secretary-General of raw materials should be Yang told reporters:" Even put an end to the use of green building materials also can not guarantee that the high levels of formaldehyde, although the company has the certification standards of the material, but the gatekeeper detection lax in the production process, but also can not guarantee that it is environmentally friendly. "

In this regard, it should be out again that the government and enterprises should work together with the management from the source of high levels of formaldehyde. The Xu Guanrong called on manufacturers to enhance the sense of responsibility and environmental awareness. At the institutional level, Lu Weiguang hope that the country will be united formaldehyde testing equipment and methods, enterprises and cities, the city and the city's testing equipment and methods to reduce the excessive formaldehyde caused by human, real consumer confidence.
