Recently, the Guangdong Quality Supervision Bureau released the results of provincial-level regular supervision and inspection of wood furniture products. A total of 87 batches of unqualified products were found. The problems involved formaldehyde emission, heavy metal content, mechanical properties, physical and chemical properties of paint film, soft and hard coating. The performance, woodworking requirements, appearance of wood-based panels and other items were unqualified, including 42 batches involving unqualified formaldehyde emission.
Excessive formaldehyde is still the "hardest hit" for unqualified furniture
According to reports, this regular supervision and inspection involves 747 batches of wood furniture products produced by 502 enterprises in 11 cities (districts) including Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Shanwei, Dongguan, Zhongshan, Jiangmen, Zhaoqing and Shunde. It was found that 87 batches were unqualified, and the unqualified product discovery rate was 11.6%. Among them, wooden furniture involves formaldehyde emission, heavy metal content, mechanical properties, physical and chemical properties of paint film, physical and chemical properties of soft and hard covering, woodworking requirements, appearance of artificial panels, etc.; children's furniture (children's furniture decoration renderings) involves structural safety ( Edge and tip), hazardous substances (formaldehyde emission, surface coating transferable element content), warning signs, appearance requirements (appearance of wooden parts) and other items.
The test results showed that there were 42 batches involving unqualified formaldehyde emission, accounting for nearly half of the unqualified batches.
Compared with the relevant standards of European and American countries, China's testing standards for formaldehyde emission from furniture are relatively loose: China's regulations on formaldehyde emission from furniture are not more than 1.5mg/L. Industry analysts believe that the main reason for the excessive formaldehyde is that manufacturers use unqualified wood-based panels and inferior adhesives to reduce costs. Most panel furniture is bonded by fiberboard or particleboard. As a result, adhesives are used for veneering and edge sealing, and the adhesive is the source of formaldehyde.
"Zero Formaldehyde" concept misunderstanding
In the past two years, the concept of “zero formaldehyde†has almost become the mainstream trend in the home furnishing industry. Whether it is a major home store or a specialty store, the “zero formaldehyde, non-toxic†banner has been everywhere. Today's consumers are paying more and more attention to the health and environmental protection of the living environment, and many are willing to pay a big price for it.
It is understood that formaldehyde belongs to Class A carcinogens. It is expected that in the environment with excessive formaldehyde, it is easy to cause irritation of eyes, skin and respiratory system, causing chronic respiratory diseases and chromosomal abnormalities. The high concentration of formaldehyde is toxic to the nervous system, liver, etc., and can cause cancer in the mouth, skin and other parts in severe cases.
When the reporter visited the home store, he noticed that although many sales people advertised "zero formaldehyde", when the reporter asked for relevant test reports, most of them failed to provide. A brand salesperson said, "Our brand has so many years of credibility. If you buy it, there will be no problem." Even for what they call “zero formaldehydeâ€, the descriptions of the sales people of different brands are very different. “The zero standard of formaldehyde is achieved by the national standardâ€, “zero formaldehyde†is the standard that meets the European standard. Plates and adhesives are truly zero formaldehyde."
So, what is the standard in the true sense of "zero formaldehyde"? Experts say that today, there are three standard formaldehyde standards, one is the national standard 1.5mg / l formaldehyde content, the other is the European standard that is 0.5mg / l Formaldehyde content, and the highest standard is Japan F4 star, ie 0.3mg / l formaldehyde content. But the real "zero formaldehyde" means no formaldehyde content.
In addition to the "zero formaldehyde" concept misunderstanding, many sales people in order to allow consumers to buy with confidence, often "support" teaches you how to see if formaldehyde exceeds the standard. "Plate furniture has a little formaldehyde, even if it meets the national standard, it is not without it. Like our brand, the sealing is good, formaldehyde can't run out." Some sales people introduced it. Experts said that the edge of the sheet is well sealed and can only reduce the amount of formaldehyde released to a certain extent, but it can not completely eliminate the release of formaldehyde. In addition, the main material used in the edge sealing process is also a binder, and there may still be formaldehyde release.
Formaldehyde detection "qualified"
A few days ago, some people in the industry broke the news. It is not uncommon for the formaldehyde inspection to be "qualified". Because of the entire production process of the sheet, the amount of formaldehyde released is unstable. Some manufacturers are opportunistic, send multiple batches, select the best quality to announce, and confuse them into the test value of formaldehyde emission from all plates. “As long as a piece of plate meets the European E0 standard, all used in one year. The material is taken for granted by E0. In addition, some manufacturers have specially treated the plates in order to meet the inspection requirements only for short-term compliance. For example, physical means such as ventilation or chemical means such as soaking water can make the formaldehyde release in a short period of time. However, the formaldehyde release cycle is 8-15 years. After a period of time, the release amount will return to the normal level, which has become a veritable stealth killer.
Experts in the industry suggest that in addition to asking for relevant reports when purchasing, consumers are best to buy a hard furniture brand. If you are not at ease, you can ask a professional organization to conduct a "climate box test" to determine the actual amount of formaldehyde released from the purchase of furniture.
