With the increasing awareness of environmental protection among people, more and more people are paying attention to the environmental performance of furniture. In customized wardrobes, cabinets, and other furniture, plywood is a common material. But is plywood an environmentally friendly material? This is a question worth exploring in depth.
1、 What is plywood
Plywood is a board made by bonding multiple layers of wood or other wooden materials with adhesive. It is a structural board with excellent mechanical properties and durability. Plywood is widely used in fields such as furniture, decoration, and construction.
The production process of plywood includes steps such as material selection, cutting, drying, gluing, pressing, and trimming. During the production process, glue is an essential material, and the quality of glue directly affects the environmental protection of plywood.
2、 What is the environmental performance of plywood
The environmental performance of plywood mainly depends on two aspects: firstly, the environmental friendliness of the board itself, and secondly, the environmental friendliness of the adhesive used.
Regarding the environmental protection of the board itself, the environmental performance of plywood is related to the raw materials used. If the raw materials used come from green plants, such as cedar, pine, etc., then the environmental friendliness of plywood is better. Because these tree species have a short growth cycle, are easy to cultivate and manage, and have little impact on the environment. At the same time, these tree species grow faster and can absorb carbon dioxide more quickly, reducing greenhouse gas emissions.
Regarding the environmental friendliness of the glue used, the type and content of glue also have a significant impact on the environmental friendliness of plywood.
There are currently three common types of adhesives in the market: urea-formaldehyde adhesive, phenolic adhesive, and melamine adhesive:
Urea-formaldehyde adhesive is the most widely used adhesive in plywood. Its advantages are low cost and high production efficiency. However, urea formaldehyde adhesive contains harmful volatile substances such as formaldehyde, which can have an impact on human health. Therefore, it is necessary to strictly control the content of volatile harmful substances in plywood made of urea formaldehyde adhesive to ensure its environmental performance.
Phenolic adhesive is a type of adhesive with good environmental performance. Its advantages are water resistance, heat resistance, good anti-corrosion performance, and no harmful volatiles. However, the phenolic adhesive has a higher cost and lower production efficiency, making it less commonly used in the market.
Melamine adhesive is a new type of environmentally friendly adhesive. Its advantage is that it does not contain harmful volatiles such as formaldehyde, and has water resistance, heat resistance, and anti-corrosion properties. However, the price of melamine adhesive is relatively high and the production process is relatively complex, so its use is relatively limited.
3、 Key points for attention
If you want to choose plywood as the material for customized wardrobes, cabinets, and other furniture, we suggest that you pay attention to the following points:
1. Choose high-quality brand plywood. Good brand plywood generally undergoes strict production processes and environmental testing, with guaranteed quality.
2. Choose plywood that meets national environmental standards. The content of harmful volatile substances such as formaldehyde in plywood that meets national environmental standards has reached the specified standard value, which is harmless to human health.
3. Choose plywood made of phenolic or melamine adhesive as much as possible. These adhesives have better environmental performance and have less impact on human health.
When using plywood furniture, pay attention to ventilation and ventilation. Especially when purchasing and returning home, furniture should be placed in a well-ventilated area to allow harmful substances to evaporate before use.
In summary, the environmental performance of plywood is related to the types of raw materials and adhesives used. If you choose plywood with an excellent brand, compliance with national environmental standards, and is made with phenolic or melamine adhesive, its environmental performance can be guaranteed. Using plywood in customized wardrobes, cabinets, and other furniture is also a good choice.
