What is the Environmental Protection Agency?
Environmental protection board is completely designed and produced by international patented technology and environmental protection standards, which has higher technical standards in formaldehyde-free, waterproof and fireproof aspects, and has the function of sustainable recycling and processing, which is the most essential difference from traditional artificial medium density board, particleboard, high-density board, multi-layer board and bite-proof board. In the production of environmentally friendly plates, some merchants cheat consumers with standard production slogans, which also makes people change clothes for environmentally friendly plates more and more. Therefore, there will be certain standards when testing environmentally friendly plates.
Environmental protection plate products are flat and smooth, with internal and external structures? Uniform, with the characteristics of good dimensional stability, high strength, environmental protection, good flame retardancy and weather resistance, and excellent machinability and surface decoration performance, it is suitable for various surface treatments and mechanical processing, and can widely replace artificial boards and natural wood. These are the inherent advantages and characteristics of the environmental protection board. Although the function is diversified, it still needs to be tested to know, so there are standards in selecting environmentally friendly plates.
Environmental protection plate standard
According to China's environmental protection standards and the concept of formaldehyde emission limit, the formaldehyde limit level in plates can be divided into three levels, namely, E2 ≤ 5.0 mg/L, E 1 ≤ 1.5 mg/L, and E0 ≤ 0.5 mg/L. In China, only plates need to meet the E2 standard, namely, E2 and e/kloc-0. However, due to the improvement of consumers' environmental awareness, there are more E 1 grade boards and even E0 grade boards on the market now. Although there are many standard grades of environmental protection board and its application range is wide, consumers still can't trust this standard environmental protection board completely, because formaldehyde can't be completely released!
E0 standard allows formaldehyde to exist in environmental protection board, but it cannot exceed 0.5mg/L, which is the highest limit. The lower limit should be the highest aldehyde content of environmentally friendly wood itself (the aldehyde content of wood itself is generally 0. 12mg/L-0.04 mg/L), which means that the lower limit is 0. 12mg/L, so consumers hesitate. Anyway, this standard environmental protection board is much more than the previous standard environmental protection board, which is very gratifying.
"Zero formaldehyde" means that the material contains no aldehyde, and no aldehyde is produced during the production reaction; It will not bring any pollution and harm to the environment and production personnel. Therefore, the "zero formaldehyde" environmental protection board is defined: the free aldehyde in the board is less than or equal to the aldehyde content of the wood itself (generally 0.04 mg/L-0. 12 mg/L). "Zero formaldehyde" environmental protection board is not the same as E0, and it is one level higher than E0 in principle.
What kinds of environmentally friendly plates are there?
Solid wood board is a kind of environmental protection board, which is made of all wood. These plates are durable and natural in texture, making them the best choice for making furniture. However, due to the high cost and high construction technology requirements, this kind of plate has not been widely used in production. Solid wood boards are generally classified according to entity names, and there is no unified standard specification. In addition to the floor and door leaves will use solid wood, commonly used plates are artificially processed wood-based panels.
Density board is a kind of environmental protection board, also called fiberboard, which is an artificial board made of wood fiber or other plant fiber and urea-formaldehyde resin or other suitable adhesives. According to the different density, it can be divided into high density board, medium density board and low density board. The MDF is soft, impact-resistant and easy to reprocess. However, because the national standard of high-density board is several times lower than the international standard, the use quality of high-density board in China needs to be improved.
Environmental protection plate grade
According to the domestic environmental protection standards and the concept of formaldehyde emission limit, the formaldehyde limit level in the board can be divided into three grades, namely, E2 ≤ 5.0 mg/L, E 1 ≤ 1.5 mg/L, and E0 ≤ 0.5 mg/L. In China, only the board needs to meet the E2 standard, namely, E2 and E/kloc-0. However, due to the improvement of consumers' environmental awareness, there are more E 1 even E0 boards on the market now.
There are many kinds of environmental protection boards, which are used in different ways and places according to their purposes, but they are also graded according to the formaldehyde limit. Therefore, you should choose carefully when buying.
It can be seen that the environmentally-friendly board is not a completely environmentally-friendly material, but also has some standards. The environmentally-friendly board that does not meet the standards is not "environmentally friendly"! The choice of this kind of building material is the most important in home improvement. Therefore, Tuba Rabbit started the "Decoration Guarantee" service from 20 12, which can effectively prevent the decoration company from using false materials, cutting corners and adding items later. We have guaranteed the decoration quality for thousands of owners in Qian Qian, and now the funds for supervising the decoration for owners have reached 100% custody!
