Title Statement
Feasibility of producing high quality, low density type particleboard Vicente C. Mallari Jr
Physical Description
25p
Summary, Etc.
Kaatoan bangkal [
Anthocephalus chinensis
(Lam) Rich. ex.Walp.] was made into a three-layer type particleboard bonded with a new type of adhesive called modified diisocyanate. Three board densities (200, 300, and 400 kg/m
3
) were produced varying their pressing conditions depending on the densities. The highest board density gave the largest values for all the mechanical properties. Dimentional stability determined particularly water absorption was also lowest compared with the lower board densities. At 400 kg/m
3
board density the following values were obtained: modulus of rupture - 6.65 MPa, modulus of elasticity - 1.48 MPa x 10
3
, internal bond strength - 0.34 MPa, screw withdrawal - 16.4 kg, thickness swelling - 11.8%, and water absorption - 68.8%. Analysis of variance and Duncan Multiple RAnge Test showed that all the data were highly significant. The use of isocyanate resin adhesive as a new binder in the production of particle board lowered down the compaction ratio of the board produced without sacrificing its properties and qualities
