In the industry, “Zero Formaldehyde has indeed become the slogan of many enterprises, and merchants have different opinions on “zero formaldehyde”. From the concept point of view, the amount of formaldehyde should be based on the authoritative test report, regardless of Whether it is a consumer or an industry practitioner, there is no need to talk about formaldehyde.
In recent years, the home furnishing industry has had a “zero formaldehyde” wind, and it seems to be getting more and more powerful.
In the major furniture stores, there are a lot of furniture that is green and zero formaldehyde. Although “zero formaldehyde furniture is more expensive than ordinary furniture, it is still favored by many consumers. Most people say that for the health of their families, they would rather spend more money to buy a peace of mind.
The author learned by visiting relevant experts, in fact, “zero formaldehyde” is the marketing method used by some merchants to use consumers’ fear of formaldehyde, and absolutely “zero formaldehyde” is almost non-existent. As a consumer, on the one hand, when purchasing furniture, it should be judged by the authoritative test report whether it is really zero formaldehyde, on the other hand, there is no need to talk about formaldehyde color change, as long as the formaldehyde content and release amount do not exceed the national standards, it will not Have an impact on human health.
Merchants say “zero formaldehyde” is not the same
In the furniture store survey, most consumers think that “zero formaldehyde is furniture, building materials will not release a trace of formaldehyde.”
The salesperson of a plate brand furniture store introduced to the author, the purchase of “zero formaldehyde products can be bought and lived.” In a full-house custom brand store, the salesperson also said: “This wardrobe is made of environmentally friendly materials, does not contain formaldehyde, and is harmless to the body. However, when I asked for the “zero formaldehyde” test report and certificate, I was rejected.
So, how to understand the “zero formaldehyde” business is mixed. Some said that the product meets the national standard is “zero formaldehyde; some said that its products meet the European standards, is absolutely “zero formaldehyde furniture; some emphasize the product “to achieve the Japanese standard can truly be called “zero formaldehyde” & rsquo;, otherwise it is a lie; there are businesses that say their furniture & ldquo; formaldehyde content tends to zero, it can be considered & ldquo; zero formaldehyde & rsquo; furniture.
Regardless of the statement, the author can see in the home market that as long as the furniture is played out, the concept of zero formaldehyde, “the value is usually 20%-30% higher than the ordinary material.
The authoritative test report shall prevail
Formaldehyde belongs to Class A carcinogens. It is expected that in the environment with excessive formaldehyde, the eyes, skin and respiratory system are easily stimulated, which leads to chronic Respiratory diseases and chromosomal abnormalities; and high concentrations of formaldehyde are harmful to the nervous system, liver, etc., and severely cause cancer in the mouth, skin and other parts.
Song Guangsheng, director of the National Indoor Interior Environment and Environmental Product Quality Supervision and Inspection Center, introduced to the author: “Formaldehyde in furniture is mainly found in urea-formaldehyde-based adhesives. Because formaldehyde has strong adhesion, it can strengthen the hardness of the board and prevent insects and corrosion.
Most of the furniture on the market needs to be processed through multiple processes such as veneering, painting and edge sealing. Most of them use adhesives containing urea-formaldehyde resin and phenolic resin. . In addition, the preservatives used to store the wood also contain formaldehyde.
Even if solid wood furniture uses environmentally friendly adhesives, it does not mean “zero formaldehyde”. It is only in the production process that no formaldehyde-containing glue is used or no artificial formaldehyde is added. It is not guaranteed that the finished product has no formaldehyde. In addition, although the environmental protection level of the board in the furniture is higher, the formaldehyde content is less, but the excessive amount of furniture placed in the room will also cause the formaldehyde emission to exceed the standard. Therefore, “zero formaldehyde furniture is almost non-existent, just a matter of how much.
However, some sales people often mention how the furniture edge-sealing technology is superb when introducing their sheet quality and “zero-formaldehyde technology: “even if the adhesive in the board contains formaldehyde, but The children were very tightly sealed, so formaldehyde could not run out. In this regard, Song Guangsheng said that the edge of the plate is well sealed, which can reduce the amount of formaldehyde released to a certain extent, but it cannot be completely eliminated. In addition, the main material used in the edge sealing process is also a binder, and there is still a release of formaldehyde.
In addition, for some merchants claiming to use furniture made of straw fiber-based “zero-formaldehyde sheet”, and thus the formaldehyde content is zero, Wang Jun, an expert member of China National Forest Products Industry Association, pointed out: “Stalk is a kind of natural plant fiber, which also contains a very small amount of formaldehyde. Does the straw use formaldehyde-containing glue in multiple processing steps, whether it will release formaldehyde in the later stage, can not listen to the words of the merchant, or take authority The test report speaks.
No need to talk about formaldehyde color change
“ The reason why zero formaldehyde furniture can become a selling point in the market, the root cause is still the consumer’s fear of formaldehyde. In this regard, Song Guangsheng reminded that the hazards mentioned here are caused by excessive formaldehyde in the environment, as long as the formaldehyde emission in the plate meets the national standard E1, that is, the formaldehyde emission is less than 1.5 mg / liter, which is not harmful to the human body.
Wang Jun pointed out that formaldehyde is notIt is so terrible that it also contains a small amount of formaldehyde in food. For example, the formaldehyde content in beer is 2 mg/L, and the fruit also contains a certain amount of formaldehyde. In addition, the content and release of formaldehyde are not the same concept. If the substrate contains formaldehyde, the amount of release is small and does not affect the human body.
There will also be real life, the formaldehyde test of the furniture is qualified, but the formaldehyde content of the indoor air is not enough. In this regard, Zhu Changling, chairman of the China Furniture Association, said: “This phenomenon may have two main reasons: First, the effect of furniture superposition, multiple furniture in the same space, the formaldehyde content released may exceed the standard; There are other formaldehyde-releasing substances in addition to furniture.
In addition to formaldehyde, there is a multi-pronged process
The release period of formaldehyde in the room will last for 3-15 years, so it is necessary to remove formaldehyde in combination with other methods. Song Guangsheng believes that it is possible to install a new fan indoors to purify formaldehyde pollution; it can also maintain convection through window ventilation; if activated carbon is used to purify formaldehyde, on the one hand, special activated carbon for formaldehyde removal should be selected; on the other hand, it must be used in wardrobes and beds. Drawers and drawers and other closed small spaces, and timely replacement, can be effective; you can also put some green plants with large leaves, such as spider plants, green radish and so on.
He also reminded consumers that formaldehyde is not judged based on the presence or absence of odor. Newly renovated and replaced new furniture rooms must be tested and then checked in.
It is understood that China’s latest revision of “Indoor Decoration Materials and Its Products in Formaldehyde Release Limits” (GB18580-2017) stipulates that formaldehyde emission from wood-based panels and their products is Not higher than 0.124 mg / cubic meter, the limit is identified as E1. The new standard will be officially implemented on May 1, 2018. By then, the environmental protection requirements of China’s furniture will be more stringent.
