Zero aldehyde furniture appeared in the market
Recently, the custom wardrobe brand Holocaust and the straw board enterprise "Wanhua Hexiang Board" jointly launched a formaldehyde-free straw board wardrobe. This product claims to use zero formaldehyde plates- furniture plates made from recyclable plant fibers ( such as rice straw, apple branches, etc. ) . In the processing technology, MDI ecological glue is used to replace the traditional urea-formaldehyde resin glue, so as to achieve zero formaldehyde emission. The reporter learned in the market that in addition to Holocaust, there are other furniture and cabinet brands on the market that have also slogan "zero formaldehyde", and its core technology is the same as Holocaust. The price of such products is often about 20% more expensive than the price of ordinary furniture .
Zero content is unscientific
So, can this plate really achieve zero formaldehyde? Luo Xin, the director of the Beijing Wood Furniture Quality Supervision and Inspection Station, said that straw fiberboard is different from ordinary man-made board. The straw fiberboard uses isocyanate glue, which is what the merchant calls MDI ecological glue to process the board, while the ordinary man-made board uses urea-formaldehyde resin. Such aldehyde adhesives. The aldehyde adhesive is formed by the reaction of formaldehyde and urea. Under natural conditions, it will continue to spontaneously decompose and reduce, and re-release free formaldehyde, which is the fundamental reason for the continuous release of formaldehyde from artificial boards, while isocyanate adhesives will not release formaldehyde. From this point of view, the formaldehyde emission of straw boards is indeed lower than that of ordinary man-made boards. But Luo Xin also pointed out that the amount of isocyanate glue used in straw boards is 10 times higher than the aldehyde adhesive used in ordinary wood-based panels , so the cost of straw boards is much higher than that of ordinary wood-based panels .
Wang Jun, an expert member of the China Forest Products Industry Association and director of the Forest Products Inspection Center (Changchun) of the State Forestry Administration, pointed out that straw is a natural plant fiber, which also contains trace amounts of formaldehyde, saying that this kind of board is completely "zero formaldehyde". Unscientific formulation. For furniture, in addition to the base material of the board, it also needs to undergo processing such as veneer, paint, and edge banding. In these processing processes, it is difficult to say that it will not bring in ingredients containing formaldehyde, and it must be completely "Zero formaldehyde" is almost impossible, at most it can be said to be close to zero formaldehyde.
No need to talk about aldehyde discoloration
The fundamental reason why "zero formaldehyde" furniture can become a selling point in the furniture market comes from consumers' fear of formaldehyde. There are terrible news that formaldehyde can cause cancer and cause leukemia everywhere in life. Regarding such rumors, Luo Xin said that the hazards mentioned here are caused by excessive formaldehyde, as long as the amount of formaldehyde released in the board meets the national standard ( E1 level: formaldehyde emission ) .
