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.

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.

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%.

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 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.

      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.,

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 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.

        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.

    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.

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.

      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.

  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.

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.

     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.

    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.

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.

Advantages:A. Good sound absorption and sound insulation performance; Thermal insulation and sound absorption of particle board;B. The interior is a cross scattered granular structure, the performance of each part is basically the same, and the lateral bearing weight is relatively poor;C. The surface of particle board is flat and can be used for various veneers;D. In the production process of particle board, the amount of glue used is small, and the environmental protection coefficient is relatively high. Shortcomings:A.

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.

   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.

     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.

Product advantages:Flame retardant density board, its surface is flat and smooth, which is convenient for secondary processing. It can be pasted with rotary cut veneer, wood veneer, painted paper, impregnated paper, etc., and can also be directly painted, printed and finished; it has good mechanical processing performance, sawing, drilling , tenoning, milling, sanding and other processing properties are similar to wood, or even better than wood. The main purpose:1. Used for hanging panels, wall panels, showcase panels, and sound-absorbing panels;2.

Medium density fiberboard    MDF has good physical and mechanical properties and processing properties, and can be made into plates of different thicknesses. Therefore, it is widely used in furniture manufacturing, construction and interior decoration industries.    Medium density fiberboard is a homogeneous porous material with good acoustic performance. It is a good material for making speakers, TV shells and musical instruments.   In addition, it can also be used for ships, vehicles, sports equipment, floors, wallboards, diaphragms, etc.

What are the factors that affect the price of density board?  1. The production of density board depends heavily on the stable supply of wood raw materials, so the price of wood affects the price of density board.2. Formaldehyde is one of the main ingredients for the production of density boards. The price of formaldehyde is highly correlated with the price of density boards. At the same time, the raw material for formaldehyde production is mainly methanol. Therefore, the prices of fossil energy such as oil, natural gas and coal also affect the price of density boards.3.
