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.

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%.

     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.

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.

     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.

The main purpose of MDF FiberboardMainly 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, and high-density boards are used for interior decoration. Exterior decoration, office and civilian furniture, audio, vehicle interior decoration, can also be used as anti-static floor in computer room and production material for wall panels, security doors, wall panels, partitions, etc. It is also a good material for packaging.

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.

    Particleboard, also known as chipboard, flakeboard, is a wood-based panel that is made of wood or other lignocellulosic materials and glued under heat and pressure after applying an adhesive. It is mainly used in furniture manufacturing and construction industry as well as train and car carriage manufacturing.Method for judging the quality of particleboard wardrobes1. From the appearance point of view, look at the size and shape of the sawdust particles in the center of the cross section. The length is generally 5-10MM.

Particleboard Quality Judgment1. From the appearance point of view, look at the size and shape of the wood chips in the center of the cross-section. The length is generally 5-10MM in length. If the length is too long, the structure is loose, and if it is too short, the deformation resistance is poor, and the so-called static bending strength does not meet the standard;2. The moisture resistance of wood-based panels depends on its density and moisture-proof agent.

Moistureproof board is to add a certain proportion of moistureproof particles in the production process of the base material, also known as melamine board (base material), which can greatly reduce the degree of expansion of the board when encountering water.  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.

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.

What is carbon crystal wooden door？ Carbon crystal is a kind of microcrystalline carbon particles purified from minerals, commonly known as high carbon graphite. This material is harder than steel and lighter than aluminum, it is high temperature resistant, corrosion resistant, and has a stable molecular structure. Carbon crystal fiber board, waterproof, zero formaldehyde, ultra-high density, is a high-end product worth having. And the carbon crystal wooden door, the wooden door made of this carbon element crystal.Advantages of carbon crystal wood doors1.

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.

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.

Why choose Xinhua Wood MDF boards?1. Competitive price.

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.

Features of MDF1. The material is uniform, the layer structure is dense, the surface is smooth and clean, not easy to deform, stable performance, smooth and delicate edges, not easy to collapse and layer; non-toxic, tasteless, non-radiation, good air permeability;2. Good heat insulation performance, no aging, strong adhesion;3.

Features of MDF:1. The internal structure is uniform, the density is moderate, the dimensional stability is good, the deformation is small, and the physical and mechanical properties are moderate.2. The surface is smooth and smooth, with good machinability. It can be pasted with sliced veneer or with novel and beautiful patterns.

1. Physical and mechanical propertiesDue to the uniform fiber structure of the board and the high bonding strength between fibers, its static bending strength, plane tensile strength, elastic modulus, and screw-holding force are better than particleboard. Hygroscopicity, water absorption performance, thickness expansion rate is low.2. Decorative performanceBecause the surface of medium density fiberboard is flat and smooth, it is easy to glue planed veneer and tissue paper and other decorative materials, and it is easy to paint and save paint.3.
