Is there really furniture without formaldehyde?

[ Chinese wardrobe net ] When the owners renovated, they always put environmental protection in the first place for the health of themselves and their families. Because of this, there is a batch of “zero formaldehyde” furniture on the market, its price It is much higher than ordinary furniture, but because of its "zero formaldehyde" has been favored by the majority of owners. But can this kind of furniture really achieve "zero formaldehyde"?

Zero formaldehyde furniture appeared in the market

Recently, the custom closet brand Hao Laike and the straw sheet enterprise “Wanhua Hexiang Board” jointly launched a zero formaldehyde straw board wardrobe. This product claims to use a zero-formaldehyde sheet using a sheet made of 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, thereby achieving zero formaldehyde emission. The reporter learned in the market that in addition to Hao Laike, there are other furniture and cabinet brands on the market that have also produced the slogan of “zero formaldehyde”, and its core technology is the same as that of Hao Laike. The price of such products is often about 20% more expensive than ordinary furniture.

Zero content is not scientific

So, can this kind of plate really achieve zero formaldehyde? Luo Wei, the director of Beijing Wood Furniture Quality Supervision and Inspection Station, said that straw fiberboard is different from ordinary wood-based panels, and straw fiberboard uses isocyanate glue, which is what merchants call MDI. Eco-adhesives are used to process sheets, while ordinary wood-based panels use aldehyde-based adhesives such as urea-formaldehyde resins. Aldehyde adhesive is formed by the reaction of formaldehyde and urea. Under natural conditions, it will spontaneously decompose and reduce, and release free formaldehyde, which is the root cause of the continuous release of formaldehyde from artificial boards, while isocyanate glue will not release formaldehyde. From this point of view, the amount of formaldehyde released from straw boards is indeed lower than that of ordinary wood-based panels. However, Luo Wei also pointed out that the amount of isocyanate glue used in straw board is 10 times higher than that of aldehyde glue used in ordinary wood-based panels, so the cost of straw board is much higher than that of ordinary artificial board.

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 a very small amount of formaldehyde, which is said to be completely zero formaldehyde. Unscientific formulation. For furniture, in addition to the substrate of the board, it also needs to be processed by veneering, painting, edge sealing, etc. In these processing, it is difficult to say that it will not bring in the ingredients containing formaldehyde, to be complete. "Zero Formaldehyde" is almost impossible, and at most it can only be said to be close to zero formaldehyde.

Don't have to talk about aldehyde color change

The reason why "zero formaldehyde" furniture can become a selling point in the market, the root cause comes from consumers' fear of formaldehyde. There are horrible news that formaldehyde can cause cancer and cause leukemia. For such rumors, Luo Wei 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)

Wang Jun pointed out that formaldehyde is not so terrible. "There is also a small amount of formaldehyde in food. For example, the formaldehyde content in beer is 2mg/L, and the fruit also contains a certain amount of formaldehyde." In addition, the content and release of formaldehyde are not the same. A concept, if the substrate contains formaldehyde, but the release is small, it will not affect the human body; if the substrate used is good, some artificial materials will release less formaldehyde than natural wood. Experts also pointed out that the lower the formaldehyde content, of course, the safer, but the price of zero-formaldehyde furniture will be higher, and it needs to be selected according to the actual needs of the family.
