Particleboard, sometimes called chipboard, is an engineered wood product manufactured from wood chips, sawmill shavings, or even sawdust, and a synthetic resin or other suitable binder, which is pressed and extruded.
Particleboard is manufactured by mixing wood particles or flakes together with a resin and forming the mixture into a sheet. The raw material to be used for the particles is fed into a disc chipper. The particles produced are then dried, after which any oversized or undersized particles are screened out. Resin is then sprayed through nozzles onto the particles.
Once the resin has been mixed with the particles, the liquid mixture is made into a sheet. A weighing device notes the weight of flakes, and they are distributed into position by rotating rakes. The sheets formed are then cold-compressed to reduce their thickness and make them easier to transport. Later, they are compressed again, and this process sets and hardens the glue. The boards are then cooled, trimmed and sanded. Panel production may involve various other chemicals as well, including wax, dyes, wetting agents, release agents, to make the final product water resistant, fireproof, insect proof, or to give it some other quality. They can be sold as raw board or surface improved through the addition of a wood veneer or laminate surface.
