Full-house customization has rapidly occupied the market since its birth and won wide favor of consumers. It includes many furniture, including wardrobe, bookcase, wine cabinet and TV cabinet, providing consumers with a personalized home decoration customization scheme of “customized clothing”.
For consumers, there are usually two ways to choose whole-house customization: brand first and then man-made board, or man-made board first and then brand.
In the face of a wide variety of dazzling wood-based panels on the market, we need to consider many factors, including quality issues, color issues, environmental protection issues, price issues, and so on.
Today we will talk about the most popular and confusing problem: how to choose an environment-friendly wood-based panel to ensure a green home environment!

01 How to understand and build a green home environment?
Environmental protection of home decoration means that before and after the decoration of the house, we should take green and low-carbon as the core concept, pay attention to resource conservation, reduce the impact on the environment, and avoid waste and other phenomena. However, for ordinary home users, we focus more on the impact of pollutants generated in home decoration on health. The country has also issued 10 standards on the limit of harmful substances in indoor decoration materials. Therefore, from the perspective of user concern, the environmental protection of home decoration is closely related to the amount of formaldehyde released from wood-based panels:
① The new house is polluted by formaldehyde
There are a lot of news about formaldehyde-induced leukaemia and other diseases in the media, such as “Formaldehyde Gate”, the original report of seven-week pregnancy in “Formaldehyde Room” for three months, abnormal fetal development and induced labor.
② Ten years of release and daily coexistence
Compared with other residential pollutants (radon, benzene and TVOC generally maintain good ventilation, and are released within a few months with little residual), formaldehyde is the slowest volatilization, with a release cycle of more than 10 years, which means that we have been living with formaldehyde since we moved into our new home.
③ High frequency of use without formaldehyde
As people are more and more inclined to customize more cabinets to meet the requirements for storage space and beautiful home decoration, wood-based panels have become more and more household decoration materials. It happens that wood-based panel is also the decoration material with the largest adhesive content. As the main source of continuous volatilization of formaldehyde, the environmental protection of wood-based panel is closely related to the emission of formaldehyde.

02 Glue is the key factor affecting formaldehyde emission of wood-based panel
What board is used to make the cabinet? Which kind of wood-based panel is more environmentally friendly?
All kinds of wood-based panels, such as Kangchun board, Kangjing board, original board, pure enjoyment board, Kangaldehyde board, Lexin board, Yixin board, Fuxin board, Jingchun board, are dazzling. What kind of health is it?
02-1 Raw materials and processes of three kinds of wood-based panels
Multi-layer board is a kind of multilayer wood-based board, which is formed by peeling or planing logs into veneer, gluing and gluing in the direction of adjacent layers of wood grain perpendicular to each other;
Particleboard is a kind of wood-based panel made from small-diameter wood, wood processing residues (slab, truncation, shavings, wood chips, sawdust), cutting residues and other plant materials processed into chips or shavings of certain specifications and shapes, and after applying adhesive, it is paved and hot-pressed;
Fiberboard is a kind of wood-based panel made from wood or other plant fibers by chipping, pulping, molding, drying, applying urea-formaldehyde resin or other suitable adhesives, and then hot pressing.
Regardless of the physical properties of wood-based panels, raw materials and the different processes caused by the differences in raw materials, the three most frequently used wood-based panels, particleboard, multilayer board and fiberboard, need to use adhesives to bond the sawdust together in the production process, and many adhesives are formed by the condensation of urea/benzene and aldehydes, such as urea-formaldehyde resin adhesive and phenolic resin adhesive, which makes the wood slowly release formaldehyde in use.
This also means that regardless of the type of wood-based panel, the type and amount of glue will determine the environmental protection degree of wood-based panel, so the following two points should be considered when selecting wood-based panel.

02-1 Select wood-based panel with environment-friendly adhesive as far as possible
Traditional adhesives, such as urea-formaldehyde resin adhesive, phenolic resin adhesive and melamine adhesive, have low cost and excellent performance, but will release formaldehyde. Therefore, the amount of glue used for wood-based panel with such adhesives needs to be specified. From the perspective of environmental protection, it is recommended to give priority to the use of formaldehyde-free adhesive. Now the wood-based panel with MDI adhesive is widely used in the market.
MDI adhesive is free of formaldehyde, and it will react with fiber to form a polymer form called polyurea (similar to plastic). This polymer structure has no volatility, so the environmental protection board made of MDI adhesive can achieve zero formaldehyde release of adhesive, and its safety and environmental protection are far better than that of urea-formaldehyde resin adhesive.

02-2 Select wood-based panel with environmental protection grade as endorsement
On October 1, 2021, GB/T 39600-2021 Classification of Formaldehyde Emission from Wood-based Panels and Their Products will be implemented soon. This standard is applicable to the classification of formaldehyde emission from various wood-based panels and their products.
After that, the level standard of formaldehyde emission in the chaotic market will be changed. Consumers need to pay attention to the corresponding level of wood-based panels while considering the adhesive used for wood-based panels. In terms of the numerical division of release, the ENF level of the new standard is absolutely at the highest level, whether it is the Japanese F-star standard or the American CARB certification.
Grade E1 ≤ 0.124mg/m ³
Grade E0 ≤ 0.050mg/m ³
ENF level ≤ 0.025mg/m ³

03 Edge banding is the environmental protection guard of wood-based panels
The rough exposed section on the side of the non-edge sealing panel of customized furniture is not only unattractive and not easy to clean, but also easy to release free formaldehyde in the base material, which has a great impact on the health of home users.
Especially remind consumers who are still using carpenters to make cabinets, do not ignore the details of edge sealing. After determining the cabinet construction drawing, they must stress with the wood-based panel manufacturer and carpenter that the cut wood-based panel needs to be edge sealed.
Common types of edge banding on the market: plastic edge banding, melamine resin impregnated paper laminated edge banding, and wood edge banding.

The edge banding problems to be noted are:
The six-sided edge sealing shall be tight, without any seam warping, and the edge sealing effect of narrow edge and end shall be paid attention to;
How about the glue quality of the edge sealing and whether the back glue is uniform to prevent it from falling off in the later stage;
How about the quality of the edge banding, whether the surface is flat, and whether there is a strong smell;
How about the strength and elasticity of the edge banding, and whether there is obvious white mark after bending;
04 Summary
No matter what kind of wood-based panel, particleboard, fiberboard or multilayer board is selected, the environmental protection of wood-based panel should be considered from the perspective of formaldehyde release, and the following three issues should be paid attention to: ① whether the adhesive contains formaldehyde; ② Whether the environmental protection grade is endorsed; ③ How about the quality of edge banding.
