     The basic unit of fiberboard is separated wood fibers or fiber bundles. The raw materials for fiber production mainly come from forest cutting residues, such as branches, shoots, small diameter wood, etc; And wood processing residues, such as board edges, shavings, sawdust, etc. In addition, the wastes from chemical processing of forest products (such as tannin extract and hydrolytic residues) and other plant stems can be used to produce fibers. The fiber content of coniferous wood is high, and the fiber length is 30-50% longer than that of hardwood.

    MDF is actually a kind of density board, which also includes short fiberboard and long fiberboard. MDF is mainly made of plant fibers or wood fibers. After the fibers are crushed, separated, and dried, a urea-formaldehyde resin or other suitable adhesive is added and pressed at high temperature. A kind of man-made board.The thickness of MDF is generally between 3mm-30mm, and the density of MDF is very high. Generally, the choice of MDF depends on the density of MDF to determine the quality of MDF. The density of MDF is generally It is in the range of 0.5-0.8g/cm³.

Why is Black Core MDF popular in the wooden door industry?     Carbon is a non-metallic element that is stable at room temperature, unreactive, and has extremely low toxicity to the human body. It can be safely ingested in the form of graphite or activated carbon. Carbon crystal, the full name of carbon microcrystal, is a crystal structure of carbon.

The production of chipboard in China has gone through a repeated process from the rise in the 1980s to the decline in the 1990s and then to the rise again in 2000.    After the particle board was abandoned by the market due to poor quality and other reasons, many particle board enterprises learned a lesson, introduced advanced production lines from abroad and improved the technology level.   After that, the quality of particle board in China has improved significantly, and it has been accepted by the market again.

MDF Mechanical propertiesBecause the fiber structure of the board is uniform and the bonding strength between fibers is high, its static bending strength, plane tensile strength, and elastic modulus are better than particleboard.

The differences between flame-retardant MDF and ordinary MDF are analyzed one by one as follows: 1. Color The color of flame-retardant MDF is dyed with red dye, so red MDF is not necessarily flame-retardant MDF Board, this point cannot be identified. 2. Physical and mechanical properties Due to the addition of flame retardants, the water-absorbing expansion of the board is affected to a certain extent. Therefore, testing the water-absorbing expansion coefficient of the board can preliminarily judge whether the flame-retardant MDF can meet the use requirements.

What is medium density fiberboard (MDF)?      Medium density fiberboard (MDF) is a kind of man-made board made of hardwood, softwood fiber or other plant fiber, which is crushed, separated, dried, applied with urea-formaldehyde resin or other suitable adhesives, and then hot-pressed. Medium-density fiberboard (MDF), generally denser than plywood, is made of separated fibers, but like plywood can be used as a building material.

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.

    Medium density fiberboard is made of wood fiber and other fibers as raw materials, prepared by fiber, then applied with synthetic glue and other functional materials, and pressed into boards with different thicknesses and densities under heat and pressure. Among them, the moisture-proof MDF is made of modified melamine cyanamide adhesive or MDI type adhesive, and the use of waterproofing agent is improved at the same time.

MDF uses are as below        1. Furniture manufacturing: At present, fiberboard is mainly used to replace natural wood for furniture production. It can produce all kinds of panel combination furniture or disassembled furniture.        2. Building materials: It can also be used to make doors, wall panels and partitions, room partitions, building components such as corners, and stair railings.        3. Vehicle and ship manufacturing: It can be used in shipbuilding, vehicle inner wall panels, roof panels, partitions, etc.

     Density board is called medium density fiberboard（MDF) . It is made of wood fiber or other plant fiber, prepared by fiber, applied with synthetic resin, and pressed under heat and pressure. According to its density, it can be divided into high-density fiberboard, medium-density fiberboard and low-density fiberboard. It is widely used in the fields of furniture manufacturing and decoration in China.Xinhua Wood Show  Xinhua Wood Machinery  Gaotang County Xinhua Wood Industry Co., Ltd.

Variety of Wood Panel1. Low density fiberboard It is a panel made of wood or plant fiber shavings that are applied with a large amount of urea-formaldehyde glue and auxiliary materials. Its density is lower than 450 kg/m3, the fiber particles are larger, the internal structure is not uniform, the strength is relatively insufficient, and the weight is light.2. Medium density fiberboardIt is a board made of wood fiber or other plant fiber, added with urea-formaldehyde adhesive, and pressed under high temperature and high pressure.

How to deal with the pungent smell of the density board?1） Keep the room ventilated and paint the MDF with anti-mildew paint.Put the density board in a dry place at home, keep the room ventilated, and it can be exposed to the sun if it is severely damp. Go to the market to buy anti-mildew paint and paint the MDF. It can play a certain role in preventing moisture and mildew, but pay attention to the quality of the paint and choose non-toxic and tasteless products.

     The density of medium density board is between the density of high density board and low density board, generally 650~880kg/m. The common specification is 2440mm*1220mm, and the thickness is 1mm, 3mm, 5mm, 9mm, 12mm, 15mm, 18mm, 25mm, etc. . MDF with other special specifications and thicknesses can also be customized.How to identify high-quality MDF?1.Surface cleanliness: There should be no obvious particles on the surface of the density board with good surface cleanliness.

According to density, it can be divided into: high-density fiberboard, medium-density fiberboard, and low-density fiberboard (the density of medium-density fiberboard is 500 kg/m3-880 kg/m3, and the density of high-density fiberboard is ≥800 kg/m3).According to the national standard (GB/T 11718-2021), it is divided into: ordinary MDF, furniture MDF and load-bearing MDF.According to the use, it can be divided into: furniture board, floor base material, door panel base material, electronic circuit board, engraving and milling board, moisture-proof board, fire-proof board and line board

Fiberboard is a kind of man-made board made of wood fiber or other plant fibers with urea formaldehyde resin or other applicable adhesives. As it is soft and impact resistant, it has high strength, uniform density after pressing, and is easy to reprocess, but its disadvantage is poor water resistance.Advantages1.Fiberboard is easy to be coated.
