zero formaldehyde is only hard to achieve for wooden furniture and floors.

furniture and floors are indispensable articles in people's homes. In the past two years, the so-called zero formaldehyde furniture, flooring in the market has been emerging, these products can really do not release a little formaldehyde? On June 3, China Home Building Materials Decoration Association Secretary General Hu Zhongxin said in an interview with reporters, natural wood would have released a small amount of aldehyde substances, wood furniture, flooring is difficult to achieve zero formaldehyde.
zero formaldehyde attracts customers' attention
, in a home square in Beijing's South Fourth Ring Road, a floor called zero formaldehyde attracted many customers. This kind of floor is expensive, the original price is more than 200 yuan/square meter, and the promotion price is 156 yuan/square meter. There is an eye-catching label on the floor, indicating "zero formaldehyde" and "environmental protection and health", and promises "free delivery and installation in Beijing Sixth Ring Road, excluding auxiliary materials, 30 square meters minimum order". "This kind of floor is made of wheat straw and uses environmentally friendly adhesive, so it does not contain formaldehyde." A salesperson introduced to reporters. However, the reporter did not see any authoritative inspection report at the sales counter.
, the reporter logged into the official website of the floor manufacturer and saw that it claimed to be able to create zero formaldehyde home space, zero formaldehyde crib, zero formaldehyde integral cabinet, geothermal floor without formaldehyde release, etc., and stressed that "the formaldehyde emission of the substrate is zero in the detection of national testing institutions such as the United States and Japan". However, the reporter noticed that the official website also indicated: "The formaldehyde emission of the brand floor is less than 0.1 mg/L, which supports testing, and the formaldehyde exceeds the standard and is returned and replaced." While claiming zero formaldehyde, it is obviously contradictory to mark the release limit of formaldehyde.
furniture and floors under the banner of zero formaldehyde are not uncommon in the market. During the investigation, the reporter found that a brand of children's furniture salesperson also tried his best to promote zero formaldehyde children's furniture to the reporter: "The furniture is all made of natural pine, and only a little glue is used. After a period of time, there will be no formaldehyde." In order to attract customers, another children's furniture manufacturer boasted that its products were 100% environmentally friendly and healthy. A flyer was posted on the brand's children's bed stating that "formaldehyde emission is lower than that of apples".
zero formaldehyde is only the direction of effort
In recent years, people pay more and more attention to environmental protection and health. Formaldehyde is considered as a strong carcinogen. Therefore, some manufacturers have hyped the concept of zero formaldehyde in order to attract consumers.
Hu Zhongxin said in an interview with reporters that naturally grown trees themselves contain a small amount of formaldehyde. In theory, all household products processed from wood will release formaldehyde more or less. It is unscientific to promote zero formaldehyde. Some so-called zero formaldehyde flooring or other wooden household products appearing on the market are suspected of misleading consumers. Objectively speaking, zero formaldehyde is only the direction of efforts of the home industry.
Hu Zhongxin said that although some manufacturers can provide test reports issued by some institutions, showing that formaldehyde is "not detected", this is not equivalent to zero formaldehyde. At present, manufacturers often use the method of inspection when conducting inspections. Whether the samples submitted for inspection and the actual mass-produced products maintain the same performance, there are still certain variables. Many domestic industries, including household products, generally have the phenomenon of "two layers of skin". Therefore, the test report can only be used as a reference for product performance.
Chang Liang, an assistant researcher at the Institute of Wood Industry of the Chinese Academy of Forestry, said that aldehyde-free wood-based panels do not mean that the formaldehyde emission of wood-based panels is absolutely zero, but that chemical or biological materials without formaldehyde are used as adhesives for wood-based panels., Such as animal and plant proteins, starch, etc. The safety of the artificial board produced by this processing is more guaranteed, and its comprehensive performance should be equal to or even exceed that of the solid board.
to reduce formaldehyde content should be multi-pronged
understood that urea-formaldehyde adhesive is commonly used by some domestic furniture and floor manufacturers. Luo Chaohui, an engineer from the Institute of Wood Industry of the Chinese Academy of Forestry, introduced to reporters that improving the ratio and synthesis process of urea-formaldehyde glue is currently one of the main ways to reduce the formaldehyde emission from wood-based panels. At the same time, the research and development of new non-aldehyde adhesives has also become a key topic for forestry research departments. Several non-aldehyde adhesives currently appearing have their own characteristics. For example, soy protein-based biological adhesives have the potential for renewable resources, but they are still in the research and development stage as a whole, and they have failed to overcome uneven materials and water resistance. Poor defects; the production process of isocyanate adhesives is relatively mature, but the price and process requirements are high, which limits its development to a certain extent.
relatively speaking, the non-aldehyde thermoplastic resin adhesives that have emerged in recent years have certain advantages. This kind of adhesive does not contain formaldehyde, no free formaldehyde is released in the production and use process, safe and environmentally friendly, simple process, and high cost performance. At the same time, thermoplastic resin as a bonding material can isolate the flow of water between the slabs, good water resistance, high stability of the plate.
Luo Chaohui analyzed that to reduce the formaldehyde emission in wooden household products, we should not only focus on the adhesive, but also start from the whole industrial chain. The low content of free formaldehyde in the adhesive does not mean that the formaldehyde emission of the produced board or furniture is low. Only through comprehensive treatment such as hot pressing process, the cooperation of wood varieties and adhesives, and post-treatment can the formaldehyde emission of wood household products be truly reduced.
