In recent years, the incidents caused by furniture in the home improvement industry have frequently entered the public eye. After the "Da Vinci Incident" last year, Vanke broke the use of Anxin "poisonous" flooring, as well as local media reports that children are sick because of excessive formaldehyde in the room. Wait. On the one hand, it reflects the chaos in the home improvement industry. On the other hand, it also reminds consumers that before purchasing furniture products, we must carefully select products that meet environmental standards, and fundamentally reduce the emission of formaldehyde. Wooden furniture has different levels of environmental protection At present, the common wooden furniture in the market is mainly divided into solid wood furniture and panel furniture. Pure solid wood furniture is not mainstream because of its high price. On the contrary, wood-based panel furniture has been loved by many families because of its detachability and price. However, behind the convenience may hide the risk. According to industry experts, even E0, E1 grade board furniture will have formaldehyde release. What is E0, E1? The E-class standard is a long-standing saying that defines the formaldehyde content of the board internationally. E0, E1 and E2 all refer to an environmental standard for the release level of formaldehyde. The two standards E1 and E2 were produced in Germany and later cited as European standards. On July 1, 2002, China promulgated and implemented the “10 mandatory national standards for hazardous materials for interior decoration materialsâ€, which stipulates that the emission of formaldehyde in E1 level must be less than or equal to 1.5mg/L, which can be directly used indoors; E2 level The formaldehyde emission of the board must be less than or equal to 5.0mg/L, and the surface of the product can be used for interior decoration after being painted. Class F standards are produced in Japan and require the most stringent environmental standards, equivalent to the highest European standard E (1/2). But even for E0 grade furniture, the formaldehyde emission can not achieve "zero emissions", but the average value is less than 0.5mg / L. But in my country, this statement has just been written into the national standard. It is still a recommended standard. According to researcher Cao Zhongrong, one of the drafters of China's plywood national standards and the Institute of Wood Research of the Chinese Academy of Forestry, the E0 grade written in China's national standard is the national standard GB/T9846.1-9846.8-2004 issued in 2004. Formally appeared, mainly indicating the limit of formaldehyde release, that is, less than 0.5mg / L, the national standard of the People's Republic of China "solid wood composite floor": a class of solid wood composite floor formaldehyde emission is less than and equal to 9 mg / 100 g; b solid wood The formaldehyde emission of the composite floor is equal to 9 mg to 40 mg/100 g, and the MDF for furniture is also in this category. Is there any "zero formaldehyde" furniture? It is worth mentioning that many consumers think that solid wood furniture is better than wood-based furniture, and that their solid wood furniture is all solid wood furniture made of whole piece of wood. However, relevant experts said: In fact, this kind of pure solid wood furniture is only a part of the solid wood furniture sold on the market, and it is expensive to manufacture, and it is easily deformed and distorted by moisture, which is not suitable for general public purchase. But since the E0 standard of panel wooden furniture is not "zero formaldehyde", what is the real "zero formaldehyde"? In fact, it means that the material is aldehyde-free, and no aldehyde is produced during the production reaction; No one brings any pollution or harm. From this we can define the "zero formaldehyde" furniture: the free aldehyde in the furniture is less than or equal to the wood's own aldehyde content (generally 0.04mg / L ~ 0.12mg / L). In short, the "zero formaldehyde" furniture principle is higher than the E0 level. For panel furniture, glue for sheet substrate bonding is essential, but it is also one of the main reasons for the production of formaldehyde in panel furniture. At present, the main glues on the market are urea aldehyde glue and phenolic glue. The former is cheap, but the amount of formaldehyde released is large; the latter is expensive and not popular. Therefore, the affordable green rubber frog glue came into being. The person in charge of the “zero formaldehyde†decoration in the home furnishing industry, the person in charge of Shenzhen Green Frog Biotechnology Co., Ltd. said that with the improvement of people's living standards, the reports of adults and children suffering from formaldehyde super-standard diseases are common in newspapers, and more and more consumers. Begin to pay attention to the standard of harmful gas emissions from furniture. At present, whether the furniture basic materials used are environmentally friendly has become one of the main indicators for people to buy furniture. However, as far as they know, the environmental standards of many well-known brands are only reaching the E1 level, which is far from the “zero formaldehyde†requirement of residents. In this regard, the research and development team of Shenzhen Green Frog Biotechnology Co., Ltd. has developed a kind of aldehyde-free glue extracted from plants, which solves the core technology of glue of slab furniture glue, green frog LW-B01 large core board, green Frog LW-B02 plywood does not contain toxic substances such as formaldehyde, benzene, toluene, xylene, cyanide, halogenated hydrocarbons, etc. It is 25 times more environmentally friendly than EO grade plates and can produce genuine non-toxic furniture. The citizens who used the green frog products said that "it's not bad, there is no bad smell, but there is a faint smell similar to bamboo."
