MDF, also known as fiberboard, is a man-made board made of wood fibers or other plant fibers and applied with urea-formaldehyde resin or other suitable adhesives. According to the different density, it is divided into high density board, medium density board and low density board. Due to its softness and impact resistance, MDF is also easy to reprocess. It is a good material for making furniture abroad. However, because the national standard for high-density board is several times lower than the international standard, the quality of MDF used in China is high. There is room for improvement, there is no doubt about that.
Advantages of MDF:
1. The surface of the MDF is smooth and clean.
2. The mdf board is easy to process and finish, and all kinds of coatings are easy to color.
3. Surface decoration materials such as veneer tape film, decorative panel, light metal sheet, melamine board can be glued on its surface.
Disadvantages of MDF:
1. MDF must contain formaldehyde
2. The nail holding force of MDF is very poor, which is far from solid wood board and particle board.
3. MDF is not waterproof and is particularly susceptible to moisture.
How to remove formaldehyde in MDF?
1. Ventilation method by opening windows: After the new house is decorated, it is usually chosen to leave the house vacant for 2 to 3 months, so that the formaldehyde, benzene and other substances left in the room during the decoration are volatilized.
2. Activated carbon adsorption method: Activated carbon can effectively remove free formaldehyde and benzene in the air.
3. Plant purification method: It is also a good choice to place a few plants in the new house to purify the air, and it can also play a role in decorating the new house.
Many manufacturers use MDF as a base material. First, it is cheaper than other panels, and the cost of manufacturers is lower.
Not all MDF contain high formaldehyde. According to their free formaldehyde, they can be divided into three environmental protection grades: E0, E1 and E2. Those that meet the national environmental protection grade can be used with confidence. Its environmental protection level is the same as that of particleboard that meets the national standard environmental protection level. It cannot be said that it is not environmentally friendly because it is a density board, that is the E1 standard.
National environmental protection grade standard:
E2 grade formaldehyde emission is ≤5mg/L
E1 formaldehyde emission is ≤1.5mg/L, which can be directly used for interior decoration
E0 grade formaldehyde emission is ≤0.5mg/L
