บทคัดย่อ
A particle board including wood particles having a maximum particle size of 3 mm and an average particle size of between 0.2 mm and 2.0 mm. The wood particles are combined with a glue, present in a concentration of 5% to 18% by weight, and 0.1% to 1% by weight of a sizing agent. The particle board components are subjected to a pressure of 15 to 50 kp/cm2 and a temperature of 120° to 210° C. to produce a particle board having a density of 600 to 1200 kg/m3 and a water absorption of 14% to 30% by weight, said swelling and absorption measured after 24 hours in water, a bending strength of 18 to 35 MPa and an internal bond strength of 1.2.
