Abstract

How hot pressing temperature , hot pressing time and the additive level of sodium silicate acted the properties of cement particle board were made by fast-curing hot pressing , using ternary quadratic orthogonal rotation design when cement/wood was 2.6 , water/cement 0.6 , hot pressing pressure 2.8 MPa , the designed density 1.2 gcm -3 , and the thickness 9 mm .The results showed that hot pressing temperature notably acted modulus of rupture (MOR), internal bowding (IB), thichness spread (TS), density , and the relationship was parabola , but it did not act modulus of elasti city (MOE);that hot pressing time notably acted MOE , IB , TS and density , and the relationship was linear ;that the additive level of sodium silicate notably acted MOR , IB and density , and the relationshp was parabola ;that the optimum hot pressing technology was that temperature was 100 ℃, time 12 min , the additive level of sodium silicate 100 gkg-1 .
