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.
Particle board 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.
Laminated 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.
Veneered Particle Board
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.
Cement Bonded Particle Board
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 , wood waste particulate like wood chips, sawdust, wooden shavings and water . 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.
Melamine Particle Board
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.
