    Particleboard is a wood-based panel processed from wood or other non-wood plants. The middle layer of the particle board is wood chips, and the two sides are finely-organized wood chips, which are formed by hot pressing with adhesives and other additives. According to the structure, it can be divided into single-layer, double-layer, and gradient structure particle boards. The surface layer of the particleboard is powder layered, and the particleboard with uniform texture is the best.

MDF product advantages and development prospects    The surface of MDF is smooth and not easily deformed, the performance is stable, and the edges are relatively strong and firm; the thermal insulation performance is good, and the tensile strength is high. These characteristics are more suitable for furniture manufacturing and interior decoration of construction projects.

How to choose good quality MDF?1.Surface cleanliness: There should be no obvious particles on the surface of the density board with good surface cleanliness. Particles are caused by impurities brought in during the pressing process, which not only affects the appearance, but also makes the paint film easy to peel off.2.Surface smoothness: When touching the surface with hands, it should feel smooth. If it feels astringent, it means that the processing is not in place.3.Surface smoothness: The surface of the density board should be bright and smooth.

What details should be paid attention to when density board is veneered?        1. Moderate pressure: generally 2~3MPa, if it is too low, it will affect the bonding strength between the base material and impregnated paper, and if it is too high, it will damage the board.        2. Hot pressing time: it depends on the curing speed of the impregnated resin and the hot pressing temperature, generally 40-50s is appropriate. If the time is too long, the resin will be over-cured, lose its proper elasticity, and cause cracks in the subsequent processing.

     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.

    The production methods of particleboard are divided into the flat pressing method of intermittent production, the extrusion method of continuous production and the rolling method according to the different slab forming and hot pressing process equipment.     In actual production, the flat pressing method is mainly used.

What is Fire Resistant MDF ?How to produce it ? What is its application?The fireproof board is a kind of board that can suppress the burning speed of the flame in the ignited state, or directly extinguish the flame.

What is FR MDF?    Fire-resistant and flame-retardant panels (FR MDF) are made by adding flame retardants and adhesives to wood fibers through continuous hot pressing. They are mostly used in public places that must meet strict fire regulations, as well as building interior decoration, production of flame-retardant furniture and flame-retardant floors, and wooden fire doors. Production, ship and vehicle interior decoration, etc.

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.

FR MDF Advantages:1.The fireproof board has low hygroscopicity, stable water-absorbing thickness expansion rate, and excellent moisture-proof performance. It is especially suitable for secondary processing such as finishes, adhesives, and paints.

 Advantages of FR MDF/Fire Resistant MDF 1.Excellent flame retardant performance: Comply with the B1 regulations of GB8624-2012 "Classification of Combustion behavior of Building Materials and Products".2.Excellent environmental protection performance: the amount of formaldehyde released reaches the level of E0 and E1 in GB18580-2017 "Limits of formaldehyde release in wood-based panels and their products for interior decoration materials"3.

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.

      The Invention of Wood-based Panels     The invention of wood-based panels can be traced back to 3000 BC. At the beginning of the 1st century BC, the Romans were already familiar with veneer manufacturing technology and plywood manufacturing principles.     In 1812, the French invented the veneer sawing machine.     In 1834, France issued a planer patent.     After 1844, the improved rotary cutting machine was officially used in industrial production.

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

The benefits of MDF:Good flexibility (Because the door panel is often pushed and pulled to open and close, if it is too hard, it will easily lead to cracking, so this advantage of MDF can just be used)Easy to shape (because it is a powder structure, and very flat and smooth, so it is easy to shape, which just meets the needs of consumers for different shapes of door panels)Xinhua Wood Factory Appearance  Xinhua Wood Storages  Xinhua Wood Machinery  Xinhua Wood Quality Certificates  Xinhua Wood Factory IntroductionGaotang County Xinhua Wood Industry Co.,

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.

Shopping skills of MDF Fiberboard:Environmental protectionAccording to national standards, MDF can be divided into E0, E1, and E2 according to its free formaldehyde content. The formaldehyde emission of E2 grade is ≤5mg/L; the formaldehyde emission of E1 grade is ≤1.5mg/L, which can be directly used for interior decoration; the formaldehyde emission of E0 grade is ≤0.5mg/L.

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 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.

Fire Resistant MDF Features:1.Excellent flame retardant performance: Comply with the B1-B/B1-C regulations of GB8624-2012 "Classification of Combustion Behavior of Building Materials and Products". 2. Excellent environmental protection performance: the amount of formaldehyde released has reached the level of E0 and E1 in GB18580-2017 "Limits of formaldehyde release in wood-based panels and their products for interior decoration materials"3.

    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.

     Particleboard, also known as chipboard, is a wood-based panel that is made of wood or other lignocellulosic materials and glued under heat and pressure after applying an adhesive.
