There is no need to "talk about aldehyde color change" when purchasing flooring.

For the health of the family, the owners always put environmental protection first in the decoration. Recently, the floor with the "zero formaldehyde" banner began to appear in the market. Although it is more expensive than the ordinary floor, it is still favored by the majority of owners. But can this floor really achieve "zero formaldehyde"?

Zero aldehyde floor appeared in the market

Recently, a plate called "zero formaldehyde" has appeared on the market - a plate 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. There are other flooring brands on the market that have also produced the “zero formaldehyde” slogan, and its core technology is similar to the same. The price of such products is often about 20% more expensive than ordinary flooring.

Zero content is not scientific

So, can this kind of plate really achieve zero formaldehyde? Experts in the industry said that straw fiberboard is different from ordinary wood-based panels. Straw fiberboard is made of isocyanate glue, which is what the merchant calls MDI ecological glue to process the board. The plate uses an aldehyde adhesive such as urea-formaldehyde resin. 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, experts 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 the floor, in addition to the substrate of the board, it 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" flooring 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).
