[ Chinese wardrobe network ] Nowadays, the social rhythm is developing more and more rapidly, but with it, many problems have erupted. We are particularly worried. As an important component of the home furnishing industry, the wardrobe will also have problems such as “milk powderâ€. The topic of health and environmental protection in the wardrobe is also coming.
The wardrobe industry often talks about the level of the board, such as E0, E1 board. The so-called E0 grade sheet, that is, the European standard formaldehyde content is less than 0.3mg/ML, the so-called E1 grade sheet, that is, the European standard formaldehyde content is less than 0.8mg/ML, and the current nationally recognized sheet formaldehyde emission standard is formaldehyde content less than 1.5mg/ML. .
At present, all brands in the market are promoting the use of E1 grade plates for their products, which have high environmental performance. However, according to industry insiders, only a few of the E1 grade plates are actually used. Some brands are simply emptying their cheques, stating that consumers will not really take environmental testing, so they will open their mouths and boast.
There are also some manufacturers, their plates are indeed E1 grades, but not the real E1 grade, but the E2 grades, after the formaldehyde treatment, can reach the E1 grade. But in fact its harm is still there. If these plates come to the consumer's home, the degree of harm will be no less than that of the previous dairy industry, which will become a health hazard.
At present, the substrates used in the wardrobe industry are mainly solid wood particle board and medium density fiberboard (ie, MDF). The solid wood particle board is pressed and crushed by wood. The inside is made of fiber shape and is still solid wood. Therefore, the nail holding force and bending resistance are relatively strong, and because of the relatively small amount of glue used in the production process, the environmental protection degree is Higher. The MDF is made of wood chips and powdered, mixed with glue, and contains more impurities inside, so the nail holding power and bending resistance are poor, and it uses a lot of glue in the synthesis process, and the environmental protection is also poor. . However, the pressure resistance of MDF is relatively strong.
However, the decision whether the board is good or bad is not whether it uses MDF or solid wood particle board, but the origin and quality of the same board. From the place of production of plates, the main production of poplar and eucalyptus in the north of China is relatively light and the hardness is not good enough. The southern part mainly produces mixed wood, which has good hardness and firmness.
From the quality level, the plates produced by different plate manufacturers vary with the purchase of raw materials, the weight of the press, the use of glue and the manufacturing process. Even the same manufacturer, there will be different A, B, C and D. Graded sheet products. Therefore, the really good sheet is made up of large-scale sheet metal producers, advanced production equipment, high-density hardwood raw materials, and superior grade A sheets produced with imported binders. However, these professional knowledge cannot be seen by ordinary consumers. Even professionals in the industry cannot identify with the naked eye, but must be authenticated by professional tests.
These substrates are used in the manufacture of furniture, and are also divided into different veneers, such as stickers, paper, melamine, PVC, solid wood, etc. The most used in the industry is the melamine surface. In comparison, the paper is attached to the paper and the ornate paper, because it has a layer of paint-like things, the environmental protection is poor, the industry uses less; paste melamine and PVC, need to go through high temperature and high pressure procedures, the most environmentally friendly, most Scratch resistance, the most commonly used in the industry; the solid wood skin, on the one hand, the higher cost, on the other hand, its environmental protection is also affected by the quality of paint and thinner, and less used in the industry.
