Since the cabinet part is invisible, the average consumer will not pay attention to this part of the material. In fact, the quality of the cabinet often affects the quality of the cabinet and its future use. Usually the cabinet plate is made of two kinds of substrates, namely particle board and medium density board.
â—The whole particleboard of the particleboard uses more particleboard. The middle layer of the particleboard is wood long fiber, and the two sides are finely organized wood fiber, which is pressed into a board. Because the flexural performance of particleboard is better than that of medium density board, it is the main material of cabinet cabinet. Almost all cabinet factories in Europe and America use particleboard. Imported particleboard meets European E1 environmental standards. The formaldehyde content is extremely low, the molecular structure is tight, the bending strength is high, and more than 50% of the cabinets use plates with green moisture-proofing agents. Such a particle board has no change under normal humidity conditions, and the overall performance can be said to be superior to the density board. At present, several large domestic factories can produce products with tight molecular structure and high flexural strength due to the use of a full set of imported equipment (investment of more than 200 million yuan). Since the sheet is mainly composed of larger wood fibers (compared to the density board), even if it is soaked in water, its expansion rate is only 8% to 10%, and it does not swell as much as the MDF. Generally speaking, if the surface decoration surface is imported from Germany, most of them are produced by large factories and used for high-grade furniture, so there are fewer problems.
Some domestic small factories can only produce some common white light board and eucalyptus board. Due to the backward equipment and production process, the produced boards are poor in bearing capacity, bending resistance and deformation strength. Whether the gap between wood chips is large or used Scratch the hand and find that it is easier to loosen, indicating that there is a problem with the board.
â—MDF is a medium-density MDF that is formed by pressing and has a good surface flatness. Therefore, when the surface needs to be boring and forming, and the surface is softer (such as a blister board), it is often used. The MDF is used to ensure that the surface of the film is flat. However, since the raw materials are all very fine wood powder, from the moisture-proof performance, if a medium-density board is immersed in water, it will expand like bread; while the particle board is immersed in water, because there are wood long fibers in the particle board, more The structure of the wood is retained, so the expansion will not expand to a certain extent, so there is no reason for the cabinet company to use the medium density board as the box material. In addition, the MDF will use a large amount of glue in the production process. If the quality of these glues is not good, the produced plates will certainly not be environmentally friendly.
Cabinet summary
According to the excellent degree of performance, it should be imported particleboard, particleboard and medium density board produced by domestic large-scale imported equipment, and the second board is made of particleboard produced by domestic small factories and double-sided white-faced MDF. Double-sided white). In addition to considering moisture and deformation resistance, another problem to be considered is whether the board is environmentally friendly. No one wants to put the tableware and food in an environment that emits harmful gases. Open the cabinet door and smell the inside. The cabinet should be odorless or have a very low odor. If there is a pungent odor, there is a problem of excessive formaldehyde. The cabinet plate is available in 18mm thick and 16mm thick. Ordering should be clear. The back panel is typically 3mm, and is also available in 5mm, single-finish and double-finished back panels.
