What is the environmental protection rating of MDF?
The density board has smooth surface, fine material, stable performance, firm edge and good decoration on the surface of the board. But the density board is poor in moisture resistance, and compared with the density board, the nail holding capacity is worse than that of particleboard. If the screw is tightened, it will be difficult to fix because of the low strength of the density board.
According to the national standard, MDF according to its free formaldehyde content can be divided into E0 class, E1 class, E2 class. E2 formaldehyde emission is less than or equal to 5mg/L; E1 formaldehyde emission is less than or equal to 1.5mg/L, can be directly used for indoor decoration; formaldehyde emission is less than or equal to E0 0.5mg/L. Consumers in the purchase of MDF, should try to buy formaldehyde emission goods, such products are more secure
1., uniform material, the plate structure is dense, smooth surface, smooth, difficult to deformation, stable performance, edge light, delicate, not easy to collapse, layered, non-toxic, tasteless, non radiation, good permeability;2., good heat insulation performance, not aging, strong adhesion;3. static bending strength, tensile strength, moisture content, screw holding force, swelling rate and formaldehyde content and other indicators are better than the national standard GB/T117181-999, GBl8580-2001 (Taiwan within the knot strength of O.74Mpa thickness swelling rate of less than 3%, moisture content is 5%).4. medium density fiberboard is more delicate than ordinary shaving board, and the finish is smooth, without drum and without delamination. It can greatly reduce material usage. Choice of MDF mainly detects formaldehyde emission and structural strength, medium density fiberboard according to formaldehyde emission levels E1, E2 and E0 level, formaldehyde emissions in general not more than 30mg/100g, as qualified products. Multi E1, E0 class in piano production.5. common materials are pine, poplar, Liu Anmu and so on. In China, MDF is already a good material for furniture manufacture and home decoration.
Common specifications for 2440mm*1220mm, thickness of 3mm, 5mm, 9mm, 12mm, 15mm, 18mm, 25mm and so on. Other special specifications and thickness MDF can also be customized.
