Comparison Of Particleboard And MDF In Restaurant Furniture Material

- Jun 11, 2018 -

The restaurant furniture particle board is broken by logs and processed by high-temperature and high-pressure processing. The middle layer of restaurant furniture particle board is wooden wood chips, and the two sides are finely organized wood chips and pressed into boards. The surface layer is powder layered, the homogeneous particle board is best, the particle board has a compact molecular structure, and the bending strength is high. The chipboard has the advantage of not easily deforming and holding nails. The disadvantage of particleboard is that it is not easy to do bending treatment or curved section processing, and it requires high processing machinery.


Restaurant furniture MDF is based on plant wood fiber as the main raw material, made by hot grinding, paving, hot pressing and other processes. Features are uniform internal structure, good machining performance, easy to engrave and make a variety of shapes, shapes and components. MDF (450-780) generally has a good surface flatness, so when the surface needs boring and milling, and the surface to be pasted is a softer material (such as a blister card), use a MDF to ensure that the film is covered. flat surface. It is generally used to strengthen wood floors, door panels and so on.


Moisture resistance: MDF is wood powder pressed and formed, the surface roughness is good, so when the surface needs boring and milling, molding, and the paste surface is a soft texture (such as plastic flower blister board), often use the medium density Board to ensure that the surface after the film is flat. However, due to the fact that the raw materials are all very fine wood powder, from the perspective of moisture resistance, if the particle board is soaked in water, because the wood fiber has long fibers in the particle board, the structure of the wood is more retained, so the particle board will not expand when it expands to a certain extent. (8%-10%). Therefore, the comprehensive performance of moisture-proof can be said that the particle board is superior to the density board. Therefore, European and American furniture kitchen cabinet companies do not have a more reasonable use of density plates for the box material.


Environmental protection: Recently, almost all restaurant furniture and kitchen cabinet factories in Europe and the United States use particleboard. For example, Germany's prestigious BERLONIROSSI, S-BEKA, etc. all use particleboard. Several domestic large factories use a full set of imported equipment (investment over 200 million yuan). It can also produce particleboard with compact molecular structure and high bending strength. In general, if the surface decoration surface is imported from Germany, most of them are produced by large factories and used for high-end furniture. Buyers and suppliers pay more attention to market reputation, so there are fewer problems. At present, there are some domestic small plants that can only produce some common common white board and wood board. Due to the backward equipment and production process, the boards produced are poor in load-bearing capacity, bending resistance and deformation strength, and the furniture is fastened. It is easy to loosen afterwards, loosen and then tighten the strength, and quickly expand after water. And the formaldehyde content is extremely high and exceeds the national standard by several times. It is very harmful to the human body. It is the quality of this type of board that has tainted the reputation of particleboard and has led consumers to mistakenly believe that the quality of the board is inferior. The history of MDF plates is not very long, and the original trees are becoming scarce, so a plate is needed instead. Therefore, density plates come out, but due to the large amount of glue used in the production process of the density plates, if the quality of these glues does not pass, or the instability will cause excessive formaldehyde in the density plates, the density plates mainly detect formaldehyde emission and structural strength and density. The board is divided into E1 grade and E2 grade according to the formaldehyde emission, and the formaldehyde emission exceeds 30mg/100g. In general, most of the MDFs of the upper-scale manufacturers are qualified. Most of the MDFs in the market are E2 grade, and E1 grade is less. Overall, particle board environmental protection coefficient is much higher than density board. And density boards are mostly used for door panels or styling, and are not really used as cabinets.


Grip nailing: restaurant furniture MDF is composed of powder, easy to expand with water. Therefore, it cannot be used as a cabinet, and because of its poor nail-typing, under ordinary circumstances, the density plate nails hit the surface and then pull it out. This way, it cannot be repeated five times, and it cannot be used anymore. However, the particle board is made of wood chips, pressed into a plate, has the characteristics of wood, has a certain nail holding power, under normal circumstances can be repeated about 10 times.


Compression Resistance: The middle layer of restaurant furniture particleboard is made of long-fiber wood, with fine wood fibers on both sides and pressed into plates. The molecular structure is tight and the bending strength is high. We have done the same experiment and used the same thickness and density of the MDF and the particle board with the same weight of 50 kg. After 2 months, the MDF severely deformed and the particle board slightly deformed. Because of its high hardness, strong nail holding ability, and good lateral load-bearing capacity, particleboard is suitable for connection between cabinets and laminates. Currently, all cabinet factories in Europe and America use particleboard, and domestic well-known cabinets also use particleboard as a cabinet. . The density plate is suitable for door panels due to its relatively uniform density. Some brands make cabinets full of particle board or density board. This is unscientific, and it can easily be deformed if it takes a long time.
