Abstract
Rubber (Hevea brasiliensis) wood (stem and branch) chips were pulped to produce hardboard for industrial use. Hardboards were made by thermo mechanical (steaming) and chemo mechanical processes for making hardboard to assess their suitability. In the thermo mechanical process chips under 7.03 kg/cm2 and 10.55 kg/cm2 digester pressure each for 30, 60 and 90 minutes. In the chemo mechanical (chemical pretreatment) process, chips were soaked in 1, 2, 3% NaOH solution under atmospheric pressure at 24 hours soaking time. Hardboards were tested for determining their modulus of rupture and water resistance properties. Results showed that chemically treated boards are stronger than steam softening boards. The boards made from rubber branches are much stronger than rubber stems.
Key Words: Branch, Chemo mechanical, Hardboard, Thermo mechanical, Rubber wood and Stem.
