National Standard for Medium Density FiberboardMedium density fiberboard is a kind of man-made board with a density of about 0.5-0.88gcm3 after processing selected wood raw materials into fibers, adding urea-formaldehyde resin and other additives, and making it through a special process.

What is the main reason for the deformation of density board?The main reason for the deformation of the density board is the production process or the storage and use process.1.

1. The use of particleboard in flooring:Particleboard is used as flooring material in temporary structures with less load. It is also widely used as a covering for hardwood floors because hardwood planks have low resistance to scratches to protect them. Wood veneer particleboard or laminated particleboard is used for floors where a finished aesthetic look is desired.2. Use of particleboard in floor underlayment:Particleboard is widely used as floor underlayment or as a basis for parquet, wooden or carpet floors.

The following aspects should be paid attention to when choosing medium density fiberboard;1. From the appearance, check whether the thickness and density are uniform, whether the corners are damaged, whether there are delamination, blister, charcolization, etc., and whether there are soft parts.2. When conditions permit, you can saw a small piece of medium density fiberboard and soak it in water with a water temperature of 20°C for 24 hours to observe its thickness change, and at the same time observe whether there are small bulges on the surface of the board.

Manufacturing Process Broadcast1. Chipping: It is the manufacturing workshop of the raw materials in the whole board production. It mainly cuts loose wood into wood chips that meet the production specifications, so as to provide better conditions for fiber separation in preparation for heat.2. Thermal grinding. The wood chips cut out of the chipping workshop are preheated and cooked, and then mechanically separated to obtain fibers.3. Fiber drying: heat grinding and sizing to make the moisture content of the fiber reach 40%-50%.

        The reason why anything appears must conform to the laws of the market. The same is true for MDF, which can be widely used mainly because of its advantages in performance and cost.

The reason for the deformation of density board furniture is here?    We all know that MDF has a wide range of applications. However, furniture made of this kind of board often has such a problem: the furniture board is deformed, which is very annoying.It not only seriously affects the normal use of our furniture, but also has a bad influence on family life. We knowThere are many reasons for this problem, and we will introduce them in detail below.1.

The difference between particleboard and density board:1. Different usesDensity board is mainly used for composite floors, door panels, partition walls, furniture, etc. In home decoration,it is mainly used for surface treatment of mixed oil technology. It can be used as the back panel of the cabinet, but it is not suitable for the cabinet body. Particleboard can be painted and veneered in various ways, and can also be used to make cabinets.2.

  According to their different densities, they are divided into high-density boards, medium density boards and low-density boards. Due to its soft and high impact strength, the density of the density board is uniform after being pressed, and it is also easy to reprocess. It is a good material for making furniture in foreign countries,but its disadvantage is poor water resistance.

Soak the common substrate and moisture-proof substrate in water at the same time, and the expansion rate of the common plate is significantly higher than that of the moisture-proof plate after two hours of expansion change. The moisture-proof board has good moisture-proof performance and is suitable for making kitchen furniture and bathroom furniture.Damp-proof board cannot be directly used on furniture, and decorative paper should be pasted on the surface. The normal practice is to soak the decorative paper in melamine solution, and then press it on after hot pressing.

      Product performance of medium density board: uniform material, dense layer structure, smooth and smooth surface, not easy to deform, stable performance, smooth and delicate edges, not easy to collapse and delaminate; non-toxic, tasteless, non-radiative, and good air permeability.MDF is mainly used for: laminate flooring, door panels, partition walls, furniture, etc., and is mainly used for the surface of mixed oil process in home decoration.Xinhua Wood Factory Scene  Xinhua Wood Machinery  Xinhua Wood IntroductionGaotang County Xinhua Wood Industry Co.,

    Moldability: Since the MDF is fibrous, it is beneficial for the machine to do carving, molding, radian and other shapes. The molded door panels and European-style lines on the market are all MDF, so MDF is more suitable for the back of the wardrobe and Door panels and moldings.Matters needing attention in making wardrobe with MDF1. From the appearance, check whether the thickness and density are uniform, whether the corners are damaged, whether there are layers, bulges, carbonization, etc., and whether there are soft parts.2.

     It is said that wall panels originated in England in the 16th century. Everyone knows that the climate in England is cold and humid. In order to block the damp and cold lower part of the wall, wall panels are used for insulation.    Another theory goes back to the Netherlands in 1300. At that time, Europe was in the dark Middle Ages, and knights wearing armor and holding long swords often scratched the walls of castles or palaces inadvertently. Protect with wood.     At the beginning, wall panels were mainly used in castles and palaces.

Where are the functions of different density boards used?1. Standard board: Standard board is a material with a smooth side and a textured finish. It is used for cabinets, drawer bottoms and wall panels that belong to hidden parts.2. Glazed panel: Glazed panel is the surface layer that has been painted, often pasted with facing bricks or stamped into facing bricks or noodle patterns, used for wall panels or wall panels around bathtubs.3. Plastic veneer: Plastic veneer is used for sliding doors, which is good in decoration and easy to clean.

The raw materials for making particleboard include wood or wood fiber materials, adhesives and additives. The former accounts for more than 90% of the dry weight of the board. The wood raw materials are mostly taken from felled wood in the forest area, small diameter wood (usually less than 8 cm in diameter), felling residues and wood processing residues. Wood chips, shavings, wood filaments, sawdust, etc. processed into flakes, strips, needles and granules are called chips.

    For furniture manufacturing, the most common and most widely used in the market is mainly MDF, with a density of 680~830KG/M3. It is widely used in the manufacture of cabinets, beds, wooden doors, tables and chairs, showcases and other furniture, as well as wooden items such as gift boxes, photo frames, stereos, props, etc. It is also a common board for interior decoration, basically most of the furniture around you Products have the material composition of density board.The surface of products with a thickness of 6mm or less can also be divided into matte and sanding effects.

     Density board, also known as fiberboard, is an artificial board made of wood fiber or other plant fiber by hot pressing after slicing, cooking, fiber separation, and drying, then applying urea-formaldehyde resin or other suitable adhesives.     The biggest advantage of MDF (medium fiberboard) is that it can be used for carving, engraving and milling, so as to make various shapes.

     In foreign countries, density board is a good material for making furniture. Density board can be selectively used to make furniture products. When we choose and buy, it is best to choose brand products. We all know that density boards are not good at holding nails, so we need to use a lot of glue for bonding when making furniture. , so we need to detect the content of formaldehyde. Density furniture uses wood-based panels as its inner material, so its material is not easy to deform, and it will not be infested with insects.

      MDF is mainly used for laminate flooring, door panels, partition walls, furniture, etc. MDF is mainly used for surface treatment of oil-mixed technology in home decoration; MDF is generally used for furniture, because the density of high-density boards is too high. It cracks easily, so there is no way to make furniture.       Generally, HDF is used for indoor and outdoor decoration, office and civilian furniture, audio, and vehicle interior decoration. It is also a good material for packaging.

   MDF is a man-made board made of wood or plant fiber, mixed with adhesives and waterproofing agents, etc., and pressed under high temperature and high pressure. It is an ideal man-made board for furniture production.Advantages of MDF:Medium density fiberboard has uniform internal structure, moderate density, strong stability, not easy to deform or crack, and durable.2. Medium density fiberboard has a smooth surface, strong plasticity, and good production and processing performance.

FeaturesThe density board surface is smooth and flat, the material is fine and dense, the performance is stable, the edge is firm, and the surface of the board is very decorative. But the density board has poor moisture resistance. In contrast, the nail-holding force of MDF is worse than that of particleboard. If the screws loosen after tightening, it is difficult to fix them at the same position.The main advantage1. Density board is easy to be painted. All kinds of paints and paints can be evenly coated on the density board, which is the first choice for paint effect.2.

Particleboard AdvantagesA. Good sound-absorbing and sound-insulating performance; Particleboard is heat-insulating and sound-absorbing;B. The interior is granular with a cross-staggered structure, the performance of each part is basically the same, and the lateral load-bearing capacity is relatively poor;C. The surface of the particle board is smooth and can be used for various veneers;D. In the production process of particleboard, the amount of glue used is small, and the environmental protection factor is relatively high.Particleboard DisadvantagesA.

What are the advantages and disadvantages of commonly used density boards in the production of showcases?Advantages of MDF1. Because the density board is hard, it is not easy to deform. At the same time, it is not easy to warp because it is made of fine wood chips. At the same time, the MDF for display cabinets has high bending resistance and impact resistance.2.

What are the advantages of decorative board MDF?    Density board, also known as fiberboard, is a man-made board made of wood fiber or other plant fiber and applied with urea-formaldehyde resin or other suitable adhesives. According to its density, it can be divided into high density board, medium density board and low density board. Due to its softness, impact resistance and easy reprocessing, MDF is a good material for making furniture abroad. Density board is easy to finishing.
