MDF is also called fiberboard. It is made by immersing wood, tree and other objects in water and then hot grinding, paving and hot pressing. It is based on lignocellulosic resin or other suitable fiber. Made of artificial boards. Because of its soft and impact resistance, high strength, uniform density after pressing, it is easy to reprocess. It is a good material for making furniture in foreign countries, but the disadvantage is poor water resistance.
The surface of the MDF is smooth and flat, the material is fine, the performance is stable, the edge is firm, and the surface of the board is well decorated. However, the density of the MDF is poor, and in contrast, the nail holding force of the MDF is worse than that of the particle board. If the screw is loose after the screw is tightened, it is difficult to fix because the strength of the MDF is not high.
Since the substrate is a powder-based material, more glue is used than the particle board, and environmental problems are more likely to occur. Secondly, due to the high glue content of the MDF, the internal structure space is small, and the moisture resistance is poor. The density of one piece is soaked in water for 24 hours. After ten hours, it is obvious that the MDF rises and deforms.
The solid wood particle board is a kind of shredded material made of wood or other lignocellulosic material, and the artificial board is glued under the action of heat and pressure after applying the adhesive. The principle is the same as the MDF.
Solid wood particle board advantages
1. The inside of the solid wood particle board is a granular shape with a cross-displacement structure. Therefore, the nail holding power is good, and the nails and screws can be nailed. These machinable properties are significantly better than MDF.
2, the solid wood particle board density is higher, the wood fiber particles in the board is larger, more retains the essence of natural wood, the content of solid wood particle board is generally less than 5% in the use of adhesive, and the environmental protection is better.
3, solid wood particle board warp deformation is small, the size is stable, the surname is good, the strength is high, the stiffness is good, and it is not easy to bend the heavy clothes. The wood-based panels currently used in the European furniture market are mainly solid wood particle boards.
Solid wood particle board
The flatness of solid wood particle board is not as good as that of MDF. It is difficult to make curvature and shape.
