Particle board for furniture

Particle board.

Particle is also widely used as material for furniture. Although not as strong as M.D.F,. particle board is considered sufficient to meet the standard quality for the manufacture of panels in the furniture industry for certain products. The panels for many products such as office furniture cabinet, bookcase, shelving, good case, credenza, table or cupboard for children today are lot of made from particle board. A panel made of particle board overlaid by wood veneer, vinyl films, plastic laminated, etc. can be used to make various kinds of furniture with a relatively cheap price and the appearance of no less attractive than wood products
.
Particle board is made from wood particles and wood flakes mixed with a resin binder pressed by using a hot press to form a sheet with various size thickness, length and width. The sizes of the board available on the market are usually available in standard sizes such as other panels. Particle board has more uniform in the properties and is not easily cracked or warped with the changing of moisture content as the wood panels. However, particle board is not a homogeneous sheet like M.D.F., he would not be as strong and flexible like the M.D.F .  Particle board can not be cut or carved to form special shapes such as the M.D.F. to make panels with the special shape ends we need a solid wood as the edge banded.
Particle board is an engineered product, therefore its properties depend completely on the materials used and processes undertaken which can be ordered and controlled at the manufacturing process.
There are some properties that need to be known from particle board:.

  •  Density.
The density particle board is varying from 28 to 62 lbs per cubic ft. Density of particle board shows the density of wood particles and resin material therein. The higher density particle board then greater strength it will be. A higher density will also increase the ability to produce smoother and tighter end.   
  •    Particles geometry.
The size and shape of individual flakes and particles in the particle board and the ratio between the particles with the resin also determine the strength and properties of particle board. The particle shape and the resin content can be controlled to create a given set of physical properties. The size, type and position will also influence the panel surface’s smoothness.

  •  Resin used.
There are 2 types of resins that are commonly used for the manufacture of particle board, urea formaldehyde and phenol formaldehyde. Urea formaldehyde is used more for interior products, while the phenol formaldehyde is used for panel that is subjected to extreme heat or humidity changes for exterior application..

  •  Moisture content.
A particle board that will be used as a panel must be controlled its moisture content to be in a balance with the moisture content with its overlay layer. A particle board is out of the manufacturer usually has standard moisture content about 7%, unless special ordered. Particle board should be kept in a special storage room that can keep its moisture content remain in a standard condition until it used.
 

The particle board products out from manufacturer, however, must pass a series of tests that guarantee to always meet the quality standards prior to shipping. The properties such as density, modulus of elasticity, modulus of rupture, internal bond, and screw holding and linear expansion are subject to a test and can be seen in the product specifications. It make a particle board has a standard quality that can be immediately known and secured when it purchased and used. This is one of the advantages of particle board than a wooden board which is a natural product that may have varies properties depending on when he lived
Finishing for particle board

A particle board is almost never used without an overlaid layer on its top. A particle board can be overlaid by wood veneer to produce an appearance like wood that to replace the wood panels. This panel, of course, requires an appropriate finishing to produce more attractive product. Particle board can also be layered with other overlay material like vinyl film, plastic laminate or decorative paper to create interesting looked product. In this case then a no more finishing is needed. An overlay with decorative model in accordance with the desired appearance is an option which is easier and cheaper.
