The meaning and differences of E0 and E1 grade plates
1： Understanding of board grade
The current board market is also uneven, and there are still quite a few cases of buying defective boards to consumers. For example, selling E1 grade boards to decoration customers with E0 grade standards requires us to understand more about ourselves when buying boards, because the main reason why many people are deceived is because they have too little knowledge about boards.
Why is there a classification of board grades? When buying boards from the material market, the board shop owner usually asks you which grade of board you need, such as E0 grade board, E1 grade board, or E2 grade board. People who are not familiar with this aspect will be a bit confused. How can there still be so many grade divisions for boards? In fact, the classification of board grade is based on the environmental protection level of the board, and its main basis is the amount of formaldehyde released by the board.
Below, let me explain the range of formaldehyde content for different grades of boards: 1.) E0: E0 ≤ 0.5mg/L (if the building material is an E0 standard, it indicates that the board meets international environmental standards, and the amount of formaldehyde released can be almost ignored) 2.) E1: E1 ≤ 1.5mg/L (E1 grade boards are national standards, and many boards in the board market are actually E1 grade) 3.) E2: E2 ≤ 5.0mg/L
2： How to distinguish authenticity of E0 grade materials
1. Identify legitimate big brands. If you want to buy genuine E0 grade boards, you still need to go to legitimate brand boards. After all, brands are the carrier of quality and strength. If big brands want to have long-term development in the industry, they must pay attention to their brand image and not take personal risks to do things that damage their reputation.
2. To distinguish the authenticity of E0 materials when looking at the environmental protection label level, you can look at the level of the environmental protection label. Generally, when I buy boards, there will be a spray code on the side of the board, which will clearly indicate the environmental protection level of the building material. We can make a basic judgment based on this.
3. Looking at the price of boards, due to the low formaldehyde emission advantage of E0 grade boards, E0 grade boards will definitely be much more expensive than E1 and E2 grade boards. Therefore, if you decide to buy E0 grade boards, you must not only think about saving money and be greedy for cheap boards. You should know that "cheap goods are not good, good goods are not suitable".
4. If you really don't know how to verify the authenticity of E0 board in the quality inspection report of the board, there is another direct, reliable and effective way, which is to ask the seller to present the national inspection report of the board.
