With the news exposure of the non-standard floor, the amount of formaldehyde released from the hot spot to the once forgotten professional words has once again become the focus of attention.
On the occasion of the March 15th, the reporter conducted a survey on the formaldehyde emission standards of artificial boards in the industry, and found that many industry standards adopted by the products made consumers' misunderstanding of formaldehyde. More consumers are confused about the current national standards, local standards and industry standards, and they are not sure which ones should prevail.
Owner found
The same is the formaldehyde release standard, the standards of merchants and countries are different?
Ms. Guo went to the two cabinets and plates factory to visit the cabinet factory last week. She praised the edge sealing and painting process of the automated cabinet factory, saying that these companies can open factories for consumers to visit. I feel very relieved. On the other hand, however, it is confusing to the standard for the release of formaldehyde on the sheet samples provided by the company.
When Ms. Guo visited the Oriental Bangtai cabinet factory, she got a sample of the board. The above notes are E1 environmental standards, and the amount of formaldehyde released.
This reporter consulted the president of China Forest Products Industry Association, Shi Feng, Shi Feng said that at present, China's formaldehyde emission standards for artificial boards have three standards: national standards, local standards and industry standards. If it is unclear, the order will actually cause Certain cognitive confusion.
Authoritative answer
The same amount of formaldehyde emission has "three different standards"!
Shi Feng said that national standards are the most instructive standard, and the other two standards should be defined on this basis, but should never be lower than national standards. For man-made boards, Fang Chongrong, deputy secretary-general and senior engineer of China National Forest Products Industry Association, explained the professional identity of the reporter in detail, that is, the term in the industry is “dip-adhesive film-finished wood-based panelâ€, “it is generally divided into particleboard and many MDF two processes, the current national standard is the relevant standard formulated in 2006, that is, should meet the E1 level. As for the E0 level that is often mentioned at present, it is a higher level standard and should be E0 "on the market. The formaldehyde grades marked by the manufacturer of the panel cabinets are in fact not in conflict with the national standard." Fang Gong said, for example, the amount of formaldehyde emitted by the Oriental Bangtai cabinet.
Expert reminder
More formaldehyde measurement methods, the most practical air detection in the home
For some netizens who forward 100g units to each other, Fanggong said that this is the standard of the first measurement method, which is obtained by the extraction method, that is, E1.
“The current standard is determined by the drier measurement methodâ€, Fang Gong explained, the test method is to place a certain size of the artificial board veneer in a desiccator, and place it in a 20 ° C environment for 24 hours. Distilled water in the desiccator surface dish, the amount of formaldehyde absorbed gives the result.
In fact, when it comes to measurement standards, it is more practical for consumers. It is actually a measure of the overall air formaldehyde content in the home. Regarding this standard, Jin Lihua, the stationmaster of the complaints station of Nanjing Decoration Materials Trade Association, gave a detailed explanation to the reporter. "According to the testing standards provided by the Nanjing Municipal Construction and Construction Committee, the formaldehyde detection of the air in the home should be carried out after one hour of sealing the doors and windows, and the air is extracted from the air above 50 cm for physical and chemical analysis. No more than 0.08 mg/m3 can be regarded as qualified." The webmaster emphasized that such testing requires self-paying, so it should be carried out in the testing process jointly designated by both parties.
The gold stationmaster suggested that consumers who have completed or are about to complete the renovation in the near future, if they are not assured of the environmental quality at home, can ask the construction company of the decoration company and the furniture brand to go to the new home inspection after the decoration is completed, so as to prevent the other party from The test report was released after the release. “Nanjing currently has at least 8 inspection structures with such qualifications. The Quality Supervision Bureau, Nanjing University, and Jiangsu Physical and Chemical Testing Center all have such qualifications.â€
