Kualitas Papan Serat Berkerapatan Tinggi Dari Sludge Terasetilasi

Abstract

This study aimed to evaluate physical properties, mechanical properties and hardboard durability of termites attack from acetylated sludge on 4 levels of acetate anhydride (0%, 3%, 5% and 7%) with 3 restats. The hardboard was made using dry process. After materials were mixed with the adhesives, they were pressed using hotpress with 170oC temperature, 45 Pa pressure for 25 minutes. The size of the hardboard sample was 25 x 20 x 1 cm with 1,2 g/cm3 density. Then physical properties (density, moisture content, water absorbtion, thickness swelling) evaluating and mechanical (modulus of elasticity, modulus of rupture, internal bond, screw holding power) evaluating were done according to JIS A 5905-2003 and durability evaluating were done according to SNI 01-7207-2006. Physical properties of hardboard JIS A 5905-2003 is density, furthermore mechanical properties didn’t fulfill. Based on the weight lost, hardboard sample was classified to class I that means very resistant to termites
