According to several media reports, the wooden furniture in various places across the country each year random checks compliance are not too optimistic, even once below 50%, the main reason for failure is excessive formaldehyde emission of raw materials. "Baby suspected home improvement reports about leukemia is not uncommon, the furniture formaldehyde emission exceeded undoubtedly great harm to the baby's body and mind.
Long-term can not be changed, formaldehyde and other toxic and hazardous substances exceeding the status quo, Shenzhen Academy of Metrology and Quality Inspection experts said, wooden furniture, especially wood-based panels style furniture, we must pay attention to the detection of furniture wood furniture quality status formaldehyde emission is exceeded.
The furniture is environmentally friendly glue is the key
Wooden furniture on the market is broadly divided into two types: solid wood furniture and wood-based panel furniture. The former due to a large number of single piece of solid wood is expensive, and the moisture easily deformed, not the first choice of the average family. In contrast, wood-based panels-furniture price close to the people, easily removable, can also achieve complete customization according to the housing structure, favored by the majority of families. Overall, wooden furniture, formaldehyde emission depends on the content the artificial board of formaldehyde used in the manufacture of furniture.
The artificial board formaldehyde reasons also divided into two: First, the wood itself in more than 100 ℃ high temperature processing of natural decomposition of the aldehyde group (the nature of many substances such as water, rice, malt and other high temperature above 100 ℃ decomposition of the aldehyde group, such substances and chemical products at room temperature volatile free formaldehyde difference is that the former is harmless to the detriment of the latter). Second, for the plate (blockboard, plywood, MDF, MDF, particle board, particle board, etc.) used in the manufacture of a large number of chemical bonding glue volatile free formaldehyde.
Sheet used mostly in MDF process must use a lot of chemical glue, so the glue is qualified for the wood-based panel style furniture became formaldehyde content standard key ring.
It is understood that the glue the adult panel furniture on the market used in MDF plates containing urea-formaldehyde glue and phenolic plastic. Urea-formaldehyde glue production process is simple, less demanding on the equipment, and more for the many small workshop production, formaldehyde emission, because of its low price, mainly wood panels, in the low-density fiberboard; the phenolic glue is a kinds of more environmentally friendly glue, its production process and equipment requirements are high formaldehyde content is relatively low, but the price is relatively much more expensive urea-formaldehyde glue, generally chosen for the grade sheet. So, if there is no free formaldehyde glue it?
Plant glue achievements in environmental protection furniture
Used as the 2010 Shanghai World Expo "Zero Carbon Museum" "Green Frog" non-toxic glue, is a plant of the plant as the raw material, the use of biological extraction technology manufacturing came, and chemical raw materials, chemical polymer technology to produce chemical glue are essentially different. This plant non-toxic glue to create the "green frog nontoxic plants plate" (Daixinban, plywood), the highest environmental protection is better than the European E0 level 25 times. Green frog nontoxic plants plate "produced" non-toxic green frog plant panel furniture "environmental protection is far more better than the market the chemical glue fiberboard panel furniture (currently on the market the best adult panel furniture environmental level only E1 class, The formaldehyde emission 9mg/100g).
Therefore, from the source to eliminate plate, furniture of excessive formaldehyde emission, must ensure that the environmental quality of the sheet and glue used in furniture production. According to Mr. Yuan, has long been engaged in renovation work, the green frog glue does not detect harmful substances, they gave the villa decoration, the owners deliberately Please detection mechanism to detect formaldehyde did not detect these harmful substances.
It is worth mentioning that the Green Frog In addition to the production of wood glue, putty adhesive, junction agents glue, wallpaper glue, blockboard, plywood, adult panel furniture production to plant non-toxic emulsion instead of chemical toxic emulsion "green frog plant non-toxic latex paint products. Up to now, the national home improvement used green frog owners have totaled about 100,000, non-toxic green frog plant decoration materials loved by the public.
