What are the methods to measure the formaldehyde content of e0 grade solid wood particle board
There are a variety of plates on the market, but people often encounter e0 and e1 grades when buying, many people have great doubts about this. Let's take a deeper look at it, and talk to you about e0 grade solid wood particle board and what methods can measure formaldehyde. Follow the editor to take a look.
1. What are E0 and E1
Before understanding the e0 grade solid wood particle board, let me tell you what E0 and E1 are. In fact, these refer to the level of formaldehyde release limit in the board, a standard to judge whether the board is environmentally friendly. The so-called E is the amount of formaldehyde contained in each liter of air. In addition, there are E2 levels. However, the common ones on the market are E0 and E1, e0 is the European standard, and e1 is the domestic standard. However, the three levels of formaldehyde limits E0, E1, E2 in the world are E0≤0.5mg / L, E1≤1.5mg / L, E2≤5.0mg / L. It is not difficult to see that the formaldehyde content of the E0 standard is the safest numerical standard, followed by E1, and then E2. Therefore, you can buy plates according to this standard.
2. How about e0 grade solid wood particle board
In fact, after reading the previous analysis, what about the e0 grade solid wood particle board? I believe the answer is already obvious. It is a plate with a higher environmental protection level. It can be said to reach the European E0 level. . At the same time, the strength of this sheet is also very good. However, the E0 grade sheet does not contain a green moisture-proof agent, and it is not glued, so its toughness and moisture-proof ability are relatively poor. However, products with a high environmental protection level are naturally more expensive and certainly expensive in production costs. Therefore, in addition to choosing according to your own preferences, you should also choose according to your actual economic ability.
3. What are the methods to measure the formaldehyde content in the plate
a. Perforation extraction method: a part of the perforation is taken out from the plate, and then the formaldehyde content is determined.
b. Climate box test method: This is a more scientific method. It is necessary to put the board in a special climate box, and then test the formaldehyde emission of the sample in the box. However, the experimental equipment of this method is expensive and the test period is long.
c. Dryer method: This method is generally adopted, which is simple and affordable. As long as the board is placed in a sealed environment, and then heated to 60 ℃ for 2 hours, the formaldehyde content released can be tested.
Editor's remarks: The above is an introduction to what is E0 and E1, e0 grade solid wood particle board and what methods can be used to measure whether the plate contains formaldehyde. I hope to help you better choose environmentally friendly plates and let yourself You and your family can live in a healthy and environmentally friendly living environment.
