What are the characteristics of MDF?
MDF is also called fiberboard, which is the degreasing and peeling of logs, crushed into wood chips, that is, wood fibers or other plant fibers as raw materials, after high temperature, high pressure, applied artificial boards made of suitable adhesives are classified into high-density boards, medium density board, low density board. Now the most common in the market is medium density board. MDF surface light and smooth, fine material, stable performance, firm edge, and the decorative surface of the board is good, has high bending strength and impact strength, easy to paint.
However, in contrast, the nail holding force of MDF is worse than that of particle board, and if the screws are loosened after tightening. Due to the low strength of MDF, it is difficult to fix it again. In addition, the biggest disadvantage of MDF is not moisture-proof, and it will swell when it sees water. When using MDF as skirting board, door cover board and window sill board, it should be noted that all six sides are painted so as not to deform.

Then touch the surface of the furniture with your hand, if there is a smooth feeling, it means that the processing is better, if it feels astringent, it means that the processing is not in place. The MDF surface should be bright and flat, as seen from the side if the surface is not flat, it means that there is a problem with the coating process of the material. In addition, the overall elasticity of the board is good. The quality of the sub-board is better, and the harder board – must be an inferior product. MDF should always be maintained during use keep dry and clean, do not rinse with a lot of water, pay special attention to avoid long MDF furniture period of immersion.
