What is Particle Board
Particle board, also known as particleboard, chipboard, and low-density fiberboard, is an engineered wood product manufactured from wood chips and a synthetic resin or other suitable binder, which is pressed and extruded. Particle board is often confused with oriented strand board (OSB, also known as flakeboard, or waferboard), a different type of fiberboard that uses machined wood flakes and offers more strength.
Advantages of Particle Board
Error is very small
The surface of the particle plate is flat. Although it is artificially made, the texture of the texture is realistic, the thickness density, and other errors are very small. The anti -pollution and aging resistance can be performed. The fragmented plate is prone to violent teeth when cutting, and has high requirements for processing equipment and process technology of details.
Processing performance
The processing performance of the particleboard is very good. It can be processed according to the requirements of the thickness according to the use of the thickness according to the use of the thickness. It is very convenient to choose the thickness of the thickness. In addition, due to the large volume of the particleboard, the furniture made with it is relatively heavy compared to other plates.
High environmental factor
The environmental protection coefficient of the particleboard is relatively high than other wood. The amount of glue is only convenient in detail, and the harmful material in the glue is avoided. The quality difference between different production products of the particleboard is relatively large, and it is not easy to distinguish; the anti -bending and tensile resistance is a little worse, and it can't help but bend and pull.
Good bearing gravity
The inside of the particle plate is the granular shape of the cross -drop structure. The performance of the directions of each ministry is basically the same, and the horizontal bearing bearing is good. However, because the edges are rough and easy to absorb moisture, it is generally not suitable as a home lining, nor can they be used to make doors and windows. It does not need to be dried again to make the particle board, which can be used directly. The effect of sound absorption and sound insulation is also very good.

Types of Particle Board
Laminated particle board is manufactured by attaching a thin layer of laminates on the surface of plain particle board. The lamination enhances beauty and increases durability of particle board. Laminated particle board is widely used to make modular kitchen, as well as wardrobes and shelves, particularly shutters, as it avoids subsequent polishing and painting.
Veneers are a very thin slice of wood which is obtained from a tree log. Veneered particle board is manufactured by attaching veneer on the top surface of the plain particle board. Veneered particle boards have more resistance to warping, as they are properly sealed. They provide the aesthetics of a natural wood in low budget cost.
As the name implies, this board uses cement as a bonding agent and has high resistant to moisture, fire and rot. Cement bonded particle board is manufactured using cement (60%), wood waste particulate like wood chips, sawdust, wooden shavings (20%) and water (20%). Due to cement content, these boards are more durable, fire-resistant and termite resistant. The cement bonded particle board has high expansion and shrinkage properties in presence of moisture. They are generally used in the production of fire resistant furniture, false ceiling, internal and external walls and permanent shuttering for concrete floors and walls.
A sheet of melamine-impregnated decor paper is attached on the top surface of the plain particle board under heat and pressure. Also, melamine-urea formaldehyde resin is used along with wax emulsion to bond the particle board and make it water resistant. Melamine particle boards are very durable and have resistant to scratches. They have application in various fields such as wall claddings, wall paneling, modular kitchen, wardrobes, and office furniture. They are available in various colours and textures to impart decorative look to the interior of your house.
Particle board is cheaper, denser and more uniform than conventional wood and plywood and is substituted for them when cost is more important than strength and appearance. Particleboard can be made more appealing by painting or the use of wood veneers on visible surfaces. Though it is denser than conventional wood, it is the lightest and weakest type of fiberboard, except for insulation board. Medium-density fibreboard and hardboard, also called high-density fiberboard, are stronger and denser than particleboard. Different grades of particleboard have different densities, with higher density connoting greater strength and greater resistance to failure of screw fasteners.
A significant disadvantage of particleboard is its susceptibility to expansion and discoloration from moisture absorption, particularly when it is not covered with paint or another sealer. Therefore, it is rarely used outdoors or in places where there are high levels of moisture, except in bathrooms, kitchens and laundries, where it is commonly used as an underlayment shielded beneath a moisture resistant continuous sheet of vinyl flooring.
In dry environments, veneered particleboard is preferred over veneered plywood because of its stability, lower cost, and convenience.
The Production Process of Particle Board
Particleboard or chipboard is manufactured by mixing particles or flakes of wood or jute-stick together with a resin and forming the mixture into a sheet. The raw material is fed into a disc chipper with between four and sixteen radially arranged blades. The chips from disk chippers are more uniform in shape and size than from other types of wood chippers. The particles are then dried, and any oversize or undersized particles are screened out.
Resin is then sprayed as a fine mist onto the particles. Several types of resins are used in the process. Amino-formaldehyde based resins are the best performing based on cost and ease of use. Urea melamine resins offer water resistance with more melamine offering higher resistance. It is typically used in external applications, with the coloured resin darkening the panel. To further enhance the panel properties, resorcinol resins can be mixed with phenolic resins, but that is more often used with marine plywood applications.
Panel production involves other chemicals including wax, dyes, wetting agents and release agents, to aid processing or make the final product resistant to water, fire or insects.
After the particles pass through a mist of resin sufficient to coat all surfaces, they are layered into a continuous carpet. This 'carpet' is then separated into discrete, rectangular 'blankets' which will be compacted in a cold press. A scale weighs the flakes, and they are distributed by rotating rakes. In graded-density particleboard, the flakes are spread by an air jet that throws finer particles further than coarse ones. Two such jets, reversed, allow the particles to build up from fine to coarse and back to fine.
The formed sheets are cold-compressed to reduce thickness and make them easier to transport. Later, they are compressed again, under pressures between 2 and 3 megapascals (290 and 440 psi) and temperatures between 140 and 220 °C (284 and 428 °F) to set and harden the glue. The entire process is controlled to ensure the correct size, density and consistency of the board.
The boards are then cooled, trimmed and sanded. They can then be sold as raw board or surface improved through the addition of a wood veneer or laminate surface.
What Are the Grades of Particle Board
Particle board is available in different grades that are defined by their usage and application. Here are some grades that are commonly available:
Industrial Grade (M2 and M3)
Can be used in cabinets, furniture and fixtures
Commercial Grade (MS)
Can be used in cabinets and laminated panels
Countertop Grade (M2)
This grade can be used in post-formed countertops and laminated panels
Shop Grade (M1)
Economy panel for non-structural applications
Application of Particle Board
Uses of particle board in flooring:
Particle board is used as a flooring material in temporary structures where there is less application of loads. Also it is widely used as covering for hardwood floors, as hardwood boards have low resistance to scratches to protect them. Wood veneer particle board or laminated particle board is used in flooring where finished aesthetic look is desired.
Uses of particle board in flooring underlayment:
Particle board is extensively used as flooring underlayment or as a base for parquet flooring, wood flooring, or for carpets. For this purpose, the particle boards are treated with special chemicals and resins to make them waterproof or termite proof.
Uses of particle board in partitioning or wall paneling:
Particle boards are used in wall partitions, as they are non-load bearing members in the structure. For cost-effective options, particle boards can be used as they have thermal and sound insulation properties. Laminated particle boards are extensively used in wall panels as they give finished walls. You can select from a variety of design in laminated particle boards for wall panels.
Uses of particle board in false ceilings:
Laminated particle boards and cement particle boards are widely used in false ceilings. Due to their thermal insulation properties they are extensively used in false ceilings for centrally air-conditioned rooms. Particle boards are extensively used as ceiling tiles for auditoriums, computer centers, cinema halls and theaters and in as display boards in commercial establishments. In building construction it is used in false ceiling and paneling due to its thermo-acoustic insulation properties.
Uses of particle board in core material for doors:
Particle boards are also used as a core material in solid core doors as well as in flush doors. Particle core is the most commonly used in manufacturing doors, as it provides flat and smooth surface for bonding with the door skin. It also has good screw-holding capacity for fixing hinges, unlike medium density fibreboard.
Uses of particle board in furniture:
There are numerous uses of particle board in furniture industry. Particle boards are extensively used in residential as well as office furniture. Wood veneer particle board are gaining popularity as they are durable and perform better in moist environment as compared to plain particle board. So they are used in kitchen areas and bathrooms in the form of modular kitchen cabinets, storage units, countertops, table tops, wardrobes and dressing units. Plain particle boards are useful in interior areas like bedrooms which have beds, wardrobes, storage units, etc. It is also used in making shoe racks, computer tables, book shelves, television cabinets, etc.
Nowadays office furniture is mass-produced by using particle boards. Readymade units of office furniture are directly supplied to the offices with decorative laminated particle board tops.
Uses of particle board in commercial industry:
On commercial scale, particle boards are used in television, speaker boxes, sewing machine tops, display boards, automobiles' parts and in other products which requires furnished surfaces. Wood veneer particle boards are very extensively used in this industry.
How to Know the Particle Board
Material
Panel board making. The raw materials of the particleboard include wood or wood fiber materials, adhesives and additives.
- Most of the wood raw materials are taken from the forest area, small diameter materials (usually below 8 cm), and the remaining objects and the remaining materials of the wood processing. Processing into pieces, strip -shaped, needle -shaped, granular wood chips, shavings, wood wires, saws, etc., called fragmented materials.
- In non -wooden materials, such as plant stalks and seed shells can also be made into plates. The name is often crowned by the name of the materials used, such as hemp straw (shavings) plates, cane residue (shavings) plates, etc.
- The adhesives are multi -teloic resin glue and phenolic resin glue. The former has a light lipstick and a low solid temperature. It has a good glue effect on the particleboard of various plant raw materials such as wheat stalks and rice shells. The hot pressure temperature is 195-210 ° C. However, there are shortcomings that release the environmentaldehyde pollution environment.
Requirements
- Appropriate water content. When the surface layer is 18 to 20%, it is conducive to the improvement of bending strength, tensile strength and surface smoothness, and reduce the possibility of layering of the drum bubbles of the plate during pressure removal. The water content of the core layer should be lower than the surface layer to maintain the proper graphic tensile strength.
- Appropriate heat pressure pressure. Pressure can affect the degree of contacation area, plate thickness deviation, and the degree of glue toasting between the thickness of the plate. According to different density requirements, thermal pressure pressure is generally 1.2 to 1.4 MPa.
- Appropriate temperature. Excessive temperature will not only break down the rigidaldehyde resin, but also cause the billet to curing in advance when heating up.
- Appropriate pressure time. If the time is too short, the middle -layer resin cannot be fully solidified. The elasticity of the finished product in the thickness direction is increasing, and the tensile strength of the plane is significantly reduced. The particleboard after the hot pressure should be balanced by the dampness treatment for a period of time, and then it should be tailored to tailor the light and inspect the packaging. However, it cannot be stacked with hot state after the pressure, otherwise it will increase the brittleness of the plate.
The Difference Between Solid Wood Granules and Particle Boards
Solid wood granular board: It is broken by wood or wooden poles, breaking, fine wood fibers on both sides, long wood fibers in the middle, and artificial boards synthesized by adhesives under the action of thermal and pressure. , Its section presents honeycomb plates.
The particle board: Also known as the fragmented material, also called the fragmented material made of wood or other woody cellulose materials. After applying the bonding agent, an artificial board synthesized under the action of thermal and pressure, also known as the fragmented plate. It is mainly used for furniture manufacturing, construction industry, train and carriage manufacturing.
Solid wood granular boards: Strong decorative performance, high physical mechanical strength, the same vertical and horizontal strength, sound insulation, mold protection, economy, insulation and other advantages. The warranty is not easy to deform, the nailing power is strong, and the processing performance is good.
Shipboard: There are good sound absorption and sound insulation performance, the particle board is insulated and sound -absorbing. The interior is the granular shape of the cross -collapsed structure. The performance of the directions of each ministry is basically the same, and the horizontal bearing gravity is relatively poor. The surface of the particle plate is flat, and various veneers can be performed. During the production process, the particleboard is small and the environmental protection factor is relatively high.
Solid wood particles: Wooden particles are woody fragmentation. This essence determines its environmental protection and avoids the second waste of materials. In foreign countries, 70%of their furniture substrates use solid wood particles. Every earth person should contribute to the sustainable development of the world. Generally, the formaldehyde content of solid wood granules with E1 -level environmental standards is low, and environmental protection performance has reached national standards.
Shellfish: During the production process of the particleboard, formaldehyde -based glue adhesives are generally used, the finished product will more or less release free formaldehyde. When the content of the formaldehyde exceeds certain limitations, it will affect human health.
Particle Board Quality
From the perspective of appearance, depending on the size and shape of the wood chips particles in the center of the horizontal section, the length is generally 5-10mm.
The moisture resistance of the artificial board depends on its density and moisture -proof agent. No matter how good the moisture and moisture resistance is soaked in the water, moisture -proof refers to moisture -proof, not waterproof. The moisture content of plates in North China, Northwest, and Northeast China should generally be controlled at 8-10%; the southern region includes 9-14%of the coastal areas, otherwise the board will easily absorb moisturizing and deformation.
In terms of surface flatness and smoothness, generally go through the light of about 200#when leaving the factory. Generally, it is fine and good, but at some times, such as sticking fireproof boards, etc. Hanging glue.
