[ Chinese wardrobe network ] Recently, Xiao Bian made a market inspection. After visiting a number of wardrobe stores, I learned that there are two kinds of mainstream plates for wardrobes, one is MDF (MDB), and the other is Solid wood particle board (particle board). When the consumer has a choice, it will be better to entangle, which is better, is it a good MDF board or a solid wood particle board? After a detailed inquiry, the guide will be patiently explained, and they all have their own advantages and disadvantages. In order to make consumers understand more, Xiaobian made a comparison between the two.
MDF/MDF
MDF is a type of MDF, including long-fiber boards and short-fiber boards. An artificial board made of wood fiber or other vegetable fiber, which is crushed, separated by fiber, dried, and then urea-formaldehyde resin or other suitable adhesive is applied, and then hot pressed. The density is generally in the range of 0.5 to 0.8 g/cm, and the thickness is generally 3 to 30 mm.
advantage
Good physical and mechanical properties
Since the fiber structure of the plate is uniform and the bonding strength between the fibers is high, the static bending strength, the plane tensile strength, and the elastic modulus are good.
Good decorative performance
Because the surface of the MDF is smooth and smooth, it is easy to glue the veneer and thin paper and other decorative materials, and it is easy to paint and save the paint.
Good processing performance
Medium density fiberboard can produce plates from a few millimeters to tens of millimeters thick, can replace any thickness of wood and square, and has good machinability, sawing, drilling, slotting, boring, sanding and engraving The edge of the board can be processed in any shape, and the surface is smooth after processing.
Disadvantages:
Poor nail holding force
The inside of the fiberboard is a powdery structure, and the nail holding force is poor. It is easy to loosen after the screw is tightened.
Poor moisture resistance
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.
Poor environmental performance
Because the substrate is a powder material, the glue used is more than the particle board. When the edge sealing process is not in place, the amount of formaldehyde released is more, which is more likely to cause environmental problems.
Purchase considerations
1. Check whether the thickness and density are uniform, whether the corners are damaged, whether there are delamination, bulging, carbonization, etc., and whether there is a soft part.
2. When conditions permit, a small piece of medium density fiberboard can be sawed in water with a water temperature of 20 ° C for 24 hours to observe the thickness change, and observe whether there is a small drum kit on the board surface. The thickness varies greatly, and there are small drums on the board surface, indicating that the board surface is poor in water resistance.
3. Select medium-density fiberboard with low release. When using olfactory smell, choose medium-density fiberboard with low odor. Because the smell is bigger, the higher the formaldehyde emission, the greater the pollution.
