Preliminary information we have learned, home, home improvement materials, formaldehyde content can not be zero, then how about the formaldehyde content of the product purchased? From which the purchase Shiyou judgment?
Learned from related practitioners detection of home improvement products currently three methods: 1, the dryer detection method, this is a way to accurately reflect the environmental performance of the flooring and other home improvement materials testing; 2, climate chamber test method, this method is use to professional formaldehyde climate chamber; 3, perforated extraction, this means to remove a small piece of material on the test, this test will cause some damage to household materials, and therefore is not recommended taken.
China as early as in July 2002 on the introduction of a the formaldehyde emission national standards, standards specified flooring formaldehyde emission is less than or equal to 1.5mg / L shall be required, in line with the requirements of indoor environmental health. All formaldehyde emissions did not meet the requirements of the new national standard, with or without the new GB detection floor, can be considered as non-green floor.
At the time of purchase, should pay attention to the manufacturers to produce the relevant agencies certified notice, etc., do not believe in the business of publicity. Also, if necessary, the relevant aspects of detection, but also with the staff of the Division I, Division I will be the person responsible to answer your questions!
According to the experts of the national indoor environmental pollution control Guidance Center, the state of the "green" wood floor there is a lot of hard targets, such as formaldehyde content. At the same time, there is a special green product certification bodies, only through the authority of the professional organization of certified products can be called "green".
I visited many brands produce environmental certification formaldehyde content are marked 0.8mg / L and 0.4mg / L or even 0.1mg / L, and some store refused to produce the certificate, but has stressed that he is an international original imported , zero formaldehyde. In this regard, Beijing Technology and Business University Professor Qian Feng: the present homogenization competition is fierce, businesses can not only meet the standards in order to attract more consumers, improve the competitiveness of its own brand, will reduce formaldehyde content fuss. consumers, which in itself is a good thing, but there are also false, defraud consumers behavior. "Therefore, Qian Feng remind consumers not only need to see their relevance in the purchase of environmentally friendly wood flooring, environmental certification, the need to identify which of the "gold", not merely on the concept of numbers in the publicity business.
In addition, for the market launch of the "zero-formaldehyde" saying Gao Zhihua, vice chairman of the China Timber Circulation Association to remind consumers, manufacturers do not believe this statement. Some manufacturers give their products play "E0" logo, claiming that the product does not contain formaldehyde. Zero formaldehyde is not possible, how much will the floor contains some, lies in its content does not exceed the national standards.
Since China does not have a unified standard furniture formaldehyde detection, detection of formaldehyde, there will be a different standard, a different test results. Formaldehyde content of the furniture industry standard currently applicable to two or harmful substances limited indoor air quality standards "and" interior decoration materials wood furniture. Which former formaldehyde content limit is ≤ 0.10 mg / cubic meter, while the latter formaldehyde content of eligibility criteria for ≤ 1.5 mg / l. "Enterprises in the production process, tend to follow a standard, the result will be in conflict with another standard, resulting the the the furniture formaldehyde content standards is not up to the contradictions of the content of formaldehyde in the air."
The Meng Star said, the furniture formaldehyde detection methods, there are some drawbacks. Such as cabinets containing multiple different plates to perforation was detected, must be carried out for each part of the destructive sampling, which often stumped consumers. He said that at present these formaldehyde detection method needs to be improved, and should develop appropriate standards.
