At present, the excessive formaldehyde emission from artificial boards is mainly due to cost issues. Choosing inferior adhesives can greatly reduce costs, but the formaldehyde emission will increase exponentially.
Formaldehyde emissions have long been a persistent problem in the wood-based panel industry. Traditional wood-based panel manufacturing requires the use of urea-formaldehyde resin adhesives, which use formaldehyde as a raw material. Even with the world's best adhesives, the resulting panels still fall short of "zero formaldehyde" standards due to trace amounts of formaldehyde present in natural wood.
However, since natural wood also contains a certain amount of formaldehyde, it means that trace amounts of formaldehyde will not cause harm to human health, so consumers can choose boards that are as close to "zero formaldehyde" as possible.
According to national environmental standards, boards with an environmental rating of E1 or higher can be used for interior decoration. E1-grade boards utilize a unique, patented glue-making process. The high-solids resin provides superior performance, ensuring the board's physical and mechanical properties while ensuring the board's free formaldehyde content meets the highest global environmental standards. Furthermore, the board utilizes the latest technology, adding solid formaldehyde-reducing powder before the core glue mixer to further reduce the formaldehyde content within the board.
Professionals point out that achieving near-zero formaldehyde emissions requires two key approaches: first, using more environmentally friendly adhesives to eliminate formaldehyde at the source; second, testing products for formaldehyde emissions to ensure quality and ensure that only products sold meet standards. Therefore, simply using high-quality adhesives cannot guarantee a board's formaldehyde emissions; more rigorous testing is required before it can be released to the market. As a result, the board's environmental rating is far above the market average.
Environmentally friendly panels can be identified from the following aspects:
1) Smell whether there is any pungent smell
2) Check whether there is a certificate issued by a national authority
3) Is the adhesive used environmentally friendly?
Of course, consumers rarely purchase wood panels directly during home renovations. However, modern furniture, cabinets, and wardrobes are widely made of artificial wood panels, making it difficult for many consumers to find the right and healthy furniture. The answer is simple: First, choose furniture from reputable brands. While this approach may not guarantee the furniture's environmental friendliness, established brands are known for their strength and the quality of the panels they use. Second, look for eco-friendly panels, such as those listed in the top ten panel brands.
