People in the industry all know that the particle board is broken by logs and processed by high-temperature and high-pressure processing. The middle layer of the particle board is wooden wood chips, and fine wood chips are formed on both sides 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.

The density board is made of plant wood fiber as the main raw material, and is made by processes such as hot grinding, paving and hot pressing. 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: Almost every European and American furniture and kitchen cabinet factory use particleboard. Several large domestic plants can use a full set of imported equipment (invested in more than 200 million yuan) to produce particle board with high 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.
