The Modification of Mechanical Properties of Changbai Mountain Smell Pine Used by Floor

摘要

In this experiment,do smell pine impregnated pressure experiments with small molecules phenolic resin.Prepare different small molecules and phenolic resin by orthogonal.Handle the specimens.Compare the treated material with the smell pine.The optimum condition is the temperature of 60°C,PVA:P (mass ratio) =3％,P∶ F∶ NaOH (molar ratio) =1∶1.2∶0.3,the absolute pressure 2.5 Mpa,the temperature of 120 °C hot 15 minutes under the conditions.While smell pine laminated veneer lumber bending strength increased 67.53％.
