TCA혈분-페놀수지가 파티클보드의 성질에 미치는 영향

The Effect of The PF-TCA Blood Adhesive on the Properties of Particleboard

This study was carried out to develop wood adhesive for the manufacture of particleboard( PB ) trom the new, simple and rapid method of isolation and purification of plasma proteins of pig bloods with trichloroacetic acid(TCA) treatment, and also consequently to prevennt water pollution PF-TCA blood adhesives were made from phenol formaldehyde resin and TCA precipitated blood. Mixed tropical hardwoods were used for the manufacture of PB. The results are as follows: 1. Physical and mechanical properties of PB from PF-TCA blood adhesive showed better than those of PF control and met the KS standard of PB 200, although TCA blood substituted for the PF solids of 70 percent. 2. Free formaldehyde emission from PB manufactured by PF - TCA blood adhesive indicated the almost same value as wood.
