Confused with the audio-visual and "zero formaldehyde" guise
A few days ago, the author found in a survey of major furniture markets that there was a wave of "counterfeit marketing" and even "false concept" marketing in the furniture market. A small number of traditional furniture merchants and people in the wood-based panel industry are making waves, trying to use ordinary man-made The board is marked with the concept of "zero formaldehyde", and then the finished furniture products made of such boards are sold to consumers at high prices.
 As we all know, the vast majority of ordinary man-made plates on the market, such as composite plates, three-plywood, plywood, etc., are made of urea-formaldehyde resin with formaldehyde as a synthetic raw material. Due to the chemical instability of urea-formaldehyde resin, as long as the artificial board using urea-formaldehyde resin can not avoid the natural decomposition of urea-formaldehyde resin in the use of the board to formaldehyde, it is impossible to achieve "zero formaldehyde".
 What's more, some merchants who are good at "packaging" apply ammonia fumigation to poor quality boards with poor environmental protection levels, or spray formaldehyde sealers on the surface, so that the boards sent for inspection can be tested for lower formaldehyde emissions As a result, the concept of "zero formaldehyde," "health," "environmental protection," "green" and so on. Compared with ordinary plates, such "specially processed" inferior plates cause more harm to consumers. Because a large number of urea-formaldehyde resins are used for inferior plates, "special processing" only covers the free formaldehyde in the plates for a short period of time, and it is powerless to decompose the formaldehyde released by the plates for a long time.
After the "masking period", formaldehyde will be released explosively.
Therefore, consumers need to understand relevant knowledge when buying furniture and choosing plates to avoid being deceived.
How many lies of "environmental protection" and "ecology" are false names?
 Environmental protection and health are the trends of furniture consumption in recent years. Carrying various banners such as "green", "environmental protection" and "ecology", holding various certifications such as "certification" and "qualification", a small number of operators often ignore the facts and ask for those who do not have professional knowledge. Ordinary consumers carry out false propaganda, such as: "Our cabinets are made of solid wood panels, which are very environmentally friendly and absolutely free of formaldehyde."
 In fact, the so-called "solid wood boards" in the market are not 100% whole logs, but block wood chips (such as large core boards), or wood flakes (such as multilayer boards) are glued with adhesives such as urea-formaldehyde resin. They differ from particle board and density board only in the degree of crushing of the wood.
 According to industry experts, the formaldehyde in furniture man-made board comes from the adhesive in the board, namely urea-formaldehyde resin. The synthetic raw materials of urea-formaldehyde resin are urea and formaldehyde. Urea-formaldehyde resin is widely used in wood-based panels because of its good bonding effect and low cost. But its biggest flaw is its easy decomposition. Urea-formaldehyde resin continuously decomposes during the use of the board, which becomes the source of formaldehyde release from furniture.
 At present, some high-grade boards adopt a method of adding a small amount of other gums or formaldehyde trapping agents to the urea-formaldehyde resin to reduce the use of urea-formaldehyde resin and achieve a higher environmental protection grade. However, due to the negative impact of these additives on the bond strength, the addition ratio is also limited. On the other hand, as long as the urea-formaldehyde resin is still used in the sheet, the formaldehyde emission will still exist. At present, the vast majority of domestically claimed "environmentally friendly" plates are only E1 grade plates.
So, is "zero formaldehyde" really a complete false propaganda?
Scarce but exists, polish your eyes and choose "zero formaldehyde"
 Industry experts told the author that at present, only man-made panels made with MDI can be called "formaldehyde-free" plates in the true sense.
 MDI's strong bonding effect can completely replace urea-formaldehyde resin. In addition, MDI is an extremely stable polymer monomer, which can produce a stable compound form with plant fibers to form a 100% solid. Therefore, there is no such defect that urea-formaldehyde resin is easily decomposed, and there is no problem of formaldehyde emission.
 At present, there are two major brands of man-made panels made in China using MDI. One is the "Wanhua Hexiang Board" produced by Wanhua Ecological Board Co., Ltd., a company directly under the SASAC, which is mainly used for furniture manufacturing and decoration; The OSB oriented particle board produced by the company Lindson is mainly used for construction and packaging.
 In addition to using MDI instead of urea-formaldehyde resin, both companies have used straw fiber instead of wood fiber. In terms of performance, it can completely replace the wooden board, so it is regarded as a "true" pure environmentally friendly product that is extremely beneficial to the human body and society.
 On the website of Wanhuahe Fragrance Board, we saw that the company's slogan was "plates that do not release formaldehyde" instead of "zero formaldehyde." The person in charge of the company explained that this is because of the difference between "content" and "emission" of formaldehyde. The materials from natural life have trace amounts of formaldehyde content, and the straw of Wanhuahe incense board also contains a very small amount of natural formaldehyde. "Zero formaldehyde" for Hexiang board means zero emission. Therefore, "sheets that do not release formaldehyde" is a more rigorous statement.
 He also introduced that the "zero formaldehyde" plate should have the "undetected" certificate from the national authoritative testing agency, and the NAF certificate from the US CARB. Consumers should carefully identify during the purchase process, and must not be credulous in "fooling".
 Due to the problems of room volume, ventilation conditions and degree of decoration, excessive use of artificial plates may easily form excessive formaldehyde accumulation in the room environment, especially the bedroom and children's room, which is extremely harmful to the body and severe cases will cause cancer, leading to leukemia and uremia , Colon cancer, brain cancer and other diseases. This may also be the fundamental reason why businesses are competing to promote "zero formaldehyde". But consumers need to keep their eyes open when buying and beware of being cheated.
