Pemanfaatan limbah padat industri penyamakan kulit (shaving) untuk papan partikel polyvinyl chlorida

The aim of this research was to study the effect of solid waste of leather tanning industry (shaving) to physical properties of PVC particle board. Particle board was produced from PVC, additives material and solid waste of leather tanning industry (shaving). The variation of solid waste (shaving) content are 0; 10; 20; 30; 40; 50; 60; and 70 phr respectively. The compound was made by mixer and two roll mill unheated, mixing by torque speed 30 rpm. Press condition are 165oC, 150 kg/cm2, and it needs 6 minutes for 2 mm thickness and 30 minutes for 10 mm thickness (depend on kinds of test). The particle board was tested physical properties by methods of SNI 03-2105-2006 Mutu Papan Partikel. The test result of physical properties showed that solid waste of leather tanning industry for particle board was significant enfluence to increased tensile strength, water contains, thickness swelling, but decreased screw withdrawl and flexibility. Solid waste of leather tanning industry (shaving) added was not significant influence to density.
