Particleboard types and manufacturing methods

Particleboard is made of wood shavings or wood fibers (such as wood chips, sawdust, etc.) and rubber compound. The rubber compound is generally urea-formaldehyde resin glue or cement.

Particleboard is divided according to the manufacturing method:

Flat pressed particle board: the applied pressure is perpendicular to the board surface, and the shavings are arranged in parallel with the board surface. According to its structure, it is divided into three types: single layer, three layer and gradient.

Extruded particle board: The applied pressure is parallel to the surface of the board, and is divided into two types: solid board and tubular hollow board according to its structure.

Particleboard is divided into surface shapes according to its surface shape:

Pressurized Particleboard: Particleboard without any surface treatment after thermoforming.

Sanding or planed particleboard: Particleboard whose surface has been mechanically sanded or planed.

Finished particleboard: A particleboard that is surface-decorated except for materials other than veneers.

Veneer facing particleboard: Particleboard that is surface-decorated with a rotary cut or sliced ​​veneer.

Particleboard is divided into shapes according to its shape:

Planar particleboard: A chipboard that is pressed against a plate.

Molded particle board: A particle board pressed with a mold.

The flat-grained particleboard is divided into two grades according to its dimensional deviation and appearance quality defects. Extrusion particleboard is not graded.

The particle size of the particleboard is: 915×915, 915×1220, 915×1525, 915×1830, 915×2135 (mm); 1000×2000 (mm); 1220×1220, 1220×1525, 1220×1830, 1220× 2135, 1220×2440
(mm).

The thickness of the particle board is: 6, 8, 10, 12, 13, 16, 19, 22, 25, 30 mm, etc.

The edge of the particleboard is not straighter than 1/1000 of the corresponding side length.

The right angle deviation of the particleboard does not exceed 1/2000 of the corresponding side length.
