Raw material of Particle board.1.Particleboard is made on the basis of scrap materials, but the range of scrap materials is relatively wide. According to different types of scrap materials, particleboard can be divided into wood particleboard, bagasse particleboard, flax chipboard, cotton stalk particleboard, Bamboo particle board, etc., cement particle board, gypsum particle board. It can be seen that most of the scraps contain wood cellulose.

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

Advantages of carbon crystal panels in customized home furnishing The carbon crystal plate is made of a PVC film on the base material. The veneer can not only play a decorative role, but also protect the inside of the plate from external erosion, replacing the position of the paint. Therefore, the carbon crystal plate is used in There is no need to paint at all times, which is very convenient and trouble-free.

Carbon Crystal Panel and Its AdvantagesCarbon crystal panel is generally used in paint-free technology, with high environmental protection and good moisture resistance. In terms of materials, they all belong to composite boards. If they are under the same brand, the quality of carbon crystal boards is better. In contrast, carbon crystal panels are waterproof, moisture-proof, environmentally friendly, formaldehyde-free, crack-resistant and non-deformable. Carbon crystal plate is a new type of high-tech environmental protection material.

Medium Density Fiberboard classification:       According to the density, it can be divided into high-density board, medium-density board, and low-density board (the density of medium-density board is 550 kg-880 kg/m3, and the density of high-density board is more than 880 kg/m3). Commonly used specifications are 1220*2440mm and 1525*2440mm, and the thickness is 2.0mm~25mm.

   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.

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.

Medium-density fiberboard is made of wood fiber or other plant fiber, applied with urea-formaldehyde resin or other synthetic resin, and pressed under heat and pressure to form a board with a density in the range of 0.50-0.88g/cm3, and other suitable materials can also be added. Additives to improve sheet properties.MDF has good physical and mechanical properties and processing properties, and can be made into plates of different thicknesses, so it is widely used in furniture manufacturing, construction, and interior decoration.

High Density Fiberboard Introduction:Density board, also known as fiberboard (full name: MDF fiberboard), is a man-made board made of wood fibers or other plant fibers with the application of urea-formaldehyde resin or other applicable adhesives.

Instruction of Waterproof FiberboardWaterproof Fiberboard, also known as fiberboard , is an artificial board made of wood fiber or other plant fibers as raw materials and urea-formaldehyde resin or other suitable adhesives.Warehouse  Xinhua Wood Company Show  Gaotang County Xinhua Wood Industry Co., Ltd. was established in April 2010 with a registered capital of 11 million yuan. It covers an area of about 76,600 square meters, including a construction area of about 22,000 square meters.

     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.

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%.

What is a Flame Retardant MDF Board?The flame retardant MDF board is a kind of board that can suppress the flame burning speed in the ignited state, or directly extinguish the flame.

The Difference Between Plywood and MDFWood fibers, resins or glues are used to make MDF. These bond together under pressure and heat to form a cardboard. Plywood is made by gluing thin hardwoods between pieces of wood.Plywood is made of solid wood while MDF is made of wood fibers. In manufacturing, there is some waste in plywood production, whereas there is no waste in MDF production.When comparing the two, it can be seen that plywood has attractive grains or knots. However, these particles or nodules are not visible in MDF.Furniture can easily be made from MDF instead of plywood.

The difference between flame-retardant MDF and ordinary MDF Appearance difference: Flame-retardant MDF is a kind of functional MDF. From the appearance, it is red, mainly because the fiber is dyed with red dye according to the international customary calendar, so as to distinguish it from ordinary MDF. Physical and mechanical properties Flame-retardant MDF is also MDF. First of all, it must have the physical mechanics of ordinary MDF to meet the use requirements.

Advantages and disadvantages of density FiberboardAdvantages:      1. The MDF surface is flat and easy to paint. All kinds of paints and paints can be evenly coated on the density board, which is the first choice for paint effect.      2. Density board is another kind of beautiful decorative board, which is better than solid wood furniture in appearance.      3. All kinds of veneer, printed paper, PVC, gummed paper film, melamine impregnated paper and light metal sheet can be decorated on the surface of MDF.      4.

MDF Products Display     MDF (Medium Density Fibreboard) is by far the most commonly used carpentry material and it is compatible with many different finishes – including simple and lacquered finishes, glued to natural boards, melamine boards and even graphic prints. They can also be used in other places, such as cladding of walls and doors.

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.

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 difference between medium density fiberboard and particle board is so bigAbstract: There are many types of man-made panels, and many friends are always unclear when they are decorating. Some friends always can't tell the difference between particleboard and density board. In fact, as long as you know the two kinds of boards, it is very simple to distinguish them.1. MDF and particle board materials are differentParticleboard is processed by high temperature and high pressure after the logs are broken, and the wood chips are the main raw materials.

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.
