There are three main types of plates, E2 is in line with domestic standards, formaldehyde content is 10-30 mg/100 g; E1 is in line with European standards, formaldehyde content is less than or equal to 9 mg/100 g, and E0 is the world's top environmental standard. The formaldehyde content is less than or equal to 3 mg / 100 g. If you have to choose E1 or above if you have the conditions, the environmental performance is better. The choice of environmentally friendly furniture is mainly considered from two aspects: The first is the board, because the environmental performance of the furniture is mainly reflected on the board, and the formaldehyde content of the good board is particularly low. There are three main types of plates, E2 is in line with domestic standards, formaldehyde content is 10-30 mg/100 g; E1 is in line with European standards, formaldehyde content is less than or equal to 9 mg/100 g, and E0 is the world's top environmental standard. The formaldehyde content is less than or equal to 3 mg / 100 g. If you have to choose E1 or above if you have the conditions, the environmental performance is better. Secondly, from the veneer, the plate finish used by good companies is more wear-resistant and scratch-resistant and does not fade. Poor finishes are not wear-resistant enough, and will gradually fade after 3-6 months, resulting in a yellowing effect. Need to pay attention to the purchase of environmentally friendly panel furniture The first thing to look at the color of the board, choose the popular color that you like, but also carefully look at the production process, including the edge sealing, the structure of the furniture is reasonable, the hardware used mainly focuses on the durability factor, the general imported hardware life is 100,000 times, equivalent to 20 years. The second is to smell and see, environmentally friendly furniture should have no irritating taste, no irritating eyes, nose, throat. The main reason is the amount of formaldehyde released. The lower the formaldehyde content of environmentally-friendly panel furniture, the better, but at the same time to ensure strength. Therefore, it is recommended to look at the formaldehyde content promised by the manufacturer at the same time as the smell, and the furniture that is not at ease should be tested by an authoritative organization. Regarding the problem of viewing, it depends on the cross section of the furniture sheet. The surface is not equal to the inside. The really environmentally friendly sheet is made of fresh wood, so the white fresh substrate can be seen after cutting, and the particles are relatively large. Tips for purchasing panel furniture 1. It is difficult to distinguish whether the board furniture is made of paper veneer or wood veneer. The easiest way is to observe the pattern, the wood veneer has natural thrift, chromatic aberration and texture changes. 2. The edge of the panel furniture is very important. Pay attention to the advantages and disadvantages of the edge-sealing material, pay attention to whether the edge banding is uneven or lifted. It is particularly important to note that it is sealed on all six sides - although formaldehyde-free adhesives are used, the wood-based panels are more or less volatile during the production process, and the edges are tightly sealed. Of course there are benefits. 3. The firmness of the furniture structure. First, the gap between the door and the drawer of the furniture. If the gap is large, it means that the work is rough, and the time will be deformed. Second, it is a single box or a double box. Usually, in addition to the outer layer, the furniture should also be inside. There is a layer of panels attached. This is called a double box. The furniture in the double box is both beautiful and strong. 4. The quality of the paint is of course also important. Are there any streaks in the pigment? Are the pigments in the corners too thick? Are there cracks or bubbles? These are all carefully examined. 5. From the hinge groove and the eye-opening area, it can be seen that the plate furniture material is medium density or particle board. One of the best methods is to carefully observe the hinge groove and the eye-punching area, and expose the internal structure. It can be seen that it is used. Particleboard is also a medium density board. 6. The use of hardware, free to disassemble and assemble is the biggest advantage of panel furniture, so the quality of the connector is closely related to the quality of the whole furniture. Imported furniture is expensive on these details. How to identify whether a door panel or partition is made of solid wood? The mystery of the wood is the wood grain and the knot. For example, if a cabinet door looks like a pattern, then the corresponding pattern of the pattern changes, and the corresponding pattern is seen on the back of the cabinet door. If the correspondence is good, it is a pure solid wood cabinet door. In addition, look at the knot is also a good way to identify pure wood, optimistic about the location of the scar side, and then find the corresponding pattern on the other side.
