There are two calculation methods for cabinets, one is by linear meters, the other is by units, no matter which calculation method, you must clearly understand consumption. The most expensive thing to buy a cabinet is the cabinet. Some consumers pay attention to the appearance when buying a cabinet, but ignore the "memory", which is the cabinet board of the kitchen cabinet. Its pros and cons often affect the quality of the cabinet. Affect future use. If you buy a computer with only a good-looking case, and the key components such as memory are poorly used, it must be used soon. The same goes for buying cabinets.
Usually the box board is made of two materials, namely particle board and medium density board. Most consumers are not clear about the difference and goodness of these two materials. The order of performance should be imported particleboard, particleboard and medium-density board produced by domestic manufacturers with imported equipment, and the inferior box board is domestic Particleboard produced by a small factory.
Particleboard: good overall performance
The middle layer of the particleboard is made of wood long fibers, and the two sides are densely organized wood fibers, which are pressed into a board. Because particle board has better bending resistance than MDF, it is the main material for cabinets.
Recently, almost all cabinet factories in Europe and America use particleboard. Imported particleboard meets the highest environmental protection standard of E1 in Europe. Among them, the formaldehyde content is extremely low, the molecular structure is tight, and the bending strength is high. More than 50% of the cabinets use green moisture-proof agent. The board, such particle board has no change in general wet conditions, and its overall performance can be said to be better than that of density board. At present, several large domestic factories use a full set of imported equipment (with an investment of more than 200 million yuan), and can also produce products with tight molecular structure and high bending strength. Since the board is mainly composed of larger wood fibers (compared to MDF), even if it is soaked in water, its expansion rate is only 8% to 10%, and it will not expand as much as MDF. Generally speaking, if the surface decoration surface is imported from Germany, most of them are produced by large factories and used for high-end furniture, so there are fewer problems.
Medium density board: general moisture resistance
MDF is formed by pressing wood powder, and the surface is smooth. Therefore, when the surface needs to be milled and formed, and the pasted surface is of soft texture (such as hollow blister board), MDF is often used. Ensure that the surface after the film is flat. However, since the raw materials are all extremely fine wood powder, from the perspective of moisture resistance, if a piece of MDF is soaked in water, it will expand like bread; while the particleboard is soaked in water, because the particleboard contains long wood fibers, more The structure of the wood is retained, so it will not expand to a certain extent. Therefore, cabinet companies do not have a certain reason for the more common use of MDF as the box material.
Particleboard produced by a small factory: not environmentally friendly
Some small domestic factories can only produce some common white light boards and beech wood boards. Due to the backward equipment and production technology, the boards produced are poor in load-bearing, bending and deformation strength, and the cabinets made are easy to loose after tightening. , The strength of tightening after loosening is insufficient, and it will expand rapidly after contact with water. In addition, the formaldehyde content is relatively high, tens of times higher than the national standard, which is very harmful to the human body. It is the quality of this kind of board that tarnishes the reputation of particleboard and makes consumers mistakenly believe that the quality of particleboard is inferior.
