Flooring and other sheet metal industries will eliminate the E2 formaldehyde emission limit regulations. Recently, this news has become the focus of discussion in the industry, because it is related to the survival and development of production companies such as flooring. At the same time, it has become the focus of attention in the decoration forum. Consumers have discussed how to buy flooring based on the amount of formaldehyde released.
The reporter learned from the interview that the relevant departments are preparing to revise the formaldehyde emission limit standards for sheet metal, and the formaldehyde emission requirements will be more stringent, posing new challenges to industry enterprises. Facing the new consumption trend of environmental protection and energy saving, seeking revolutionary innovation of materials, pursuing the release of "zero formaldehyde", creating a blue ocean in the industry and becoming a new direction leading the development of the industry.
Formaldehyde release limits are stricter
Recently, news came out that the National Standards Committee is about to revise the mandatory national standard GB18580-2001 "Limits for Formaldehyde Release in Interior Decoration Materials, Artificial Panels and Their Products", and the E2 standard in the original standard will be eliminated.
Li Jiafeng, Chairman of the Floor Committee of the China Wood and Wood Products Distribution Association, confirmed the above news. He said that E2 grade boards are more suitable for outdoor and packaging applications, and formaldehyde release requirements will be more stringent. "Standards come out, it is also an improvement to the industry."
In China, there are two levels of formaldehyde release limits for wood-based panels and their products: E2≤5.0mg / L and E1≤1.5mg / L. The stricter E0 level (≤0.5mg / L) appears as a recommended standard in "Plywood" (GB / T9846.1 ~ 9846.8) and is not mandatory. Compared with the difference of one order of magnitude from E0 to E1, the difference between E2 and E1 is 3.5 orders of magnitude. The large difference in values ​​between levels is a major reason why the industry believes that the standard is unscientific.
According to Li Jiafeng, throughout the domestic plate industry companies, they are currently pursuing "zero formaldehyde" technology, the formaldehyde emission is small or negligible, and Europe, Japan, etc. are also developing in this regard, especially large brand companies pay more attention to health Environmental indicators.
The industry believes that if the newly revised formaldehyde emission limit standard is introduced, it will have an impact on companies producing flooring and floor adhesives. Adhesives that originally met the E2 standard are prohibited from use, increasing the production costs of some companies. However, the requirements for formaldehyde emission limits are becoming stricter, which is the trend of the industry. At present, the entire floor industry is still performing well in this respect. The production standards of most companies have already reached E1 and even E0 levels. As to when the new national standard will be revised, no news has yet been obtained.
Adhesive quality should be valued
"Formaldehyde exceeding the standard is harmful, especially to children." Hu Huijun, deputy secretary general of the Floor Committee of the China Wood and Wood Products Distribution Association, said mild formaldehyde poisoning can cause dizziness and dizziness, and severe cases may cause leukemia or even life-threatening.
According to Hu Huijun, the harm of formaldehyde mainly comes from the base material of wooden floors and furniture, and the adhesive is the key to the formaldehyde release or not. The lower price and poor quality of urea-formaldehyde glue will evaporate more formaldehyde, especially sheet furniture, low density The board is even more terrible, the small workshop is the hardest hit area for unqualified adhesive application.
At present, the concept of "zero formaldehyde" is flying all over the market, but experts remind consumers not to be superstitious about the concept. Even large-scale and expensive plate products have a certain amount of formaldehyde. The safety premise is that the release limit meets the standard requirements. A number of consumer coordination research activities have shown that whether the product is environmentally friendly is closely related to the raw material of the plate, and the environmental protection of the plate is closely related to the adhesive used. At present, there are many domestic manufacturers of wood-based panels, mainly small and medium-sized enterprises, and the products are mixed. The most direct victims are consumers.
"It is not a question of technical difficulty, but a question of cost." Li Jiafeng pointed out that the wooden materials of home building materials themselves contain formaldehyde, so there is no absolute "zero formaldehyde" product. The key is to see whether an adhesive without formaldehyde is used. The quality of the clear adhesive. At present, enterprises in the industry are pursuing "zero formaldehyde", there is no technical difficulty, more is the problem of cost investment, reluctant to buy better glue.
The emergence of wheat straw board
Can wheat straw in the farmland be used as a plate? Many people can't believe it, but when the market gives good feedback, this doubt is completely dispelled.
The reporter learned from Nuofiboer Board Holdings (China) Co., Ltd., which is mainly engaged in the production of low-carbon healthy plates, that at present, kindergartens, middle schools, office buildings (office decoration renderings) and other public areas sensitive to health The scope of application is gradually extended to meet people's demand for high-quality products and quality of life, which will lead the development direction of the sheet metal industry.
As a German-funded enterprise, based on patented technology, Nofiborg uses high-quality natural wheat straw as raw material, supplemented with formaldehyde-free p-MDI adhesive, and heat-presses a whole set of processing technology to produce oriented structure wheat straw board.
In the Nofibor Beijing office, the company's CEO Professor Pentax took a piece of directional structure wheat straw substrate and told reporters why the formaldehyde release in wheat straw plates is extremely low: compared to wood-based plates, wheat The raw material of the straw board is zero-formaldehyde wheat straw, and the adhesive used for bonding the wheat straw belongs to the ester glue, that is, the formaldehyde-free adhesive. The trace amount of formaldehyde content comes from the waxy material used in the surface processing of the board, or from the low formaldehyde adhesive that bonds wood and wheat straw.
In September 2013, 29 consumer rights protection units such as the Tianjin Consumers Association issued the "Comparison Experiment Report on Environmental Performance of Floor and Panel", which tested 28 flooring samples and 7 panel samples. Among them, the 7 board samples are mainly selected from the market that declares low formaldehyde or uses aldehyde-free glue.
It is worth noting that in the above experiment report, the formaldehyde emission of a non-wood-based artificial board is only 0.05mg / 100g, which is "conspicuous" in 35 tested samples, which is exactly Nofi Bor Manufactured formaldehyde-free wheat straw board.
Is it a concept to use wheat straw as a board? Is the intensity enough? Is it durable? Faced with such a new product, many people can not help but doubt. But the answers of industry experts are simple and clear.
"Straw board, turning waste into treasure, is a good thing." Hu Huijun said that the amount of formaldehyde released from the board is closely related to the adhesive, and the formaldehyde released from the inorganic glue is very low, almost no. Consumers need to buy from regular channels when buying, compare more, especially the quality of adhesives.
Pentax explained the reliability of wheat straw materials from another perspective. "Think of how many heavy wheat ears can be hung on a seemingly slender wheat straw. In fact, the strength and toughness of wheat straw fiber is far from being 'soft' as many people think."
Pentax said that through its original manufacturing process of directional structural plates, Nofiborg plates have the characteristics of high structural strength, strong load-bearing performance, formaldehyde "zero" emissions, moisture and insect resistance, and easy processing. They can be widely used in construction engineering, interior decoration, Furniture flooring, packaging industry and other fields are a new generation of energy-saving and environmentally friendly, green and healthy wood-based products.
Binder emphasized that the quality of the directional structure wheat straw board can be seen from the quality of p-MDI adhesive alone. The price of p-MDI glue is relatively high. Compared with traditional urea-formaldehyde glue, it has a price difference of 30% to 40%. The quality is outstanding. The directional structure of wheat straw board produced with it has extremely low formaldehyde emission, which has reached "not detected" in professional testing. At the same level, consumers can buy applications with confidence.
