Particle board is an engineered wood product manufactured from wood chips or jute-stick chips and a synthetic resin or other suitable binder, which is pressed and extruded. source: Wikipedia
Particle board, or in some countries, is called a chipboard, is a type of engineered wood. Made from pieces of wood or even sawdust. Come together by chemistry And bring it to be compacted with high pressure Particleboard is classified as a type of fibreboard and particle board is chopped into small pieces of rubber wood mixed with glue and then extruded into wood panels. The wood is “sticky but not tight” with the advantage of its toughness. From interlocking fibers But the wood will not fluff and rough if you take anything hard. To scrape down on the wood The wood will break up. In wood there are small cavities which make wood lighter than real wood. Often used to make furniture or built-in furniture, not often spray paint, but instead use other materials to cover the surface.
Production process of plywood pieces (Particle board)
Manufacturing process Start from the process of preparing the wood pieces. When the logs are obtained, they will be sent to a cutting machine, but if they are scraps, they will be sent to another wood chipper. After that, it is sent to the barn, the damp wood pieces are stored and sent to the dry wood dryer until about 2-3% moisture remains, then they are sent to the dry wood barn and sent to a grader. (AIRSEPARATOR) An oversized piece of wood is sent to the wood chipper (KNIFFLINK FLAKER) to the desired size before being passed to the barn and weighing scale.
The perfectly sized pieces of wood are passed to the weighing scale, then the process of glue mixing with the wood pieces is passed through a special MATHFORMING MACHINE. The body on the steel belt under the plate maker goes into MENDE PRESS, which will be applied between the big hot roller (HEATED PRESS DRUM) and the small pressing roller liver continuously at a temperature of 180 degrees Celsius.
In continuous length, PARTICLE BOARD production will generate dust due to the polishing of PARTICLE BOARD these factories. There is a vacuum cleaner installed. To eliminate air pollution that can cause respiratory disease and dust This dust can also be recycled. Part of which will be made into fuel in the production process Another part will be reused to produce new PARTICLE BOARD sheets and fine dust that can be sold to incense manufacturers as well. This is beneficial to manufacturers and the changing global environment.
Production raw materials – Important raw materials in PARTICLE BOARD production are
- wood or material containing lignin, or Cellulose (eg bagasse), which these raw materials can be found domestically
- Rubber wood is abundant in the South and the East.
- Eucalyptus wood is found throughout the country.
- Wood waste is everywhere from sawmills and lumber mills around the country.
- The glue is used to bind the wood pieces together. Using urea-formaldehyde-based glue Or other synthetic glue For different purposes Which can be purchased within the country It can also be purchased from nearby countries such as Malaysia -WAX and other chemicals. Can be purchased from dealers in the country.
Properties of wood (Particle board)
Particle board that It is the lightest wood among fibreboards. The strength is less than the MDF and hardwood. Another disadvantage of the particle board is The wood itself is easily expanded. Due to moisture, especially wood that has not been painted or that has been sealer coated Particleboard, however, is most commonly used in indoor woodworking. Replace the outdoor work with high humidity. Particle boards are used over the counter. Used as insulation from
Standard size of wood (Particle board)
Particle Board is a piece of wood made from natural wood to crush. They are small pieces and are pressed into sheets with heat, special adhesives and compression and chemical processing. To be able to prevent moisture and termites. It will be produced as prefabricated sheets size 1200 x 2400 mm. And size 1800 x 2400 mm. And have different thickness sizes such as thickness 3 mm., 9 mm., 16 mm., 19 mm. , Etc.
In which the produced sheets are still bare sheets To be taken off the skin Outside before using to produce furniture
- Standard thickness: 9, 12, 15, 16, 18, 19 and 25 mm.
- Base size: 1220 x 2440 mm.
- Density: 160-450 kg / m 3
Type of wood (Particle board)
Particle board is a product made from a piece of rubber wood that can no longer provide latex. They are formed into sheets under pressure and used as a binder. Particle board has 3 layers: the upper surface layer and the lower surface layer. And the inner gut layer Rougher The raw material used to produce particle board is the expired rubber wood.
