Abstract
There are vast quantities of agricultural residues available in Tanzania. Rice husk being amongst those residues is reported to have low resistance to alkalis, high silica content, and have short fibres. These factors have made rice husks not attractive raw materials in panels’ production. However, it has been demonstrated that rice husks can be used to develop panel products of low cost and good performance if appropriate indigenous technologies and affordable binders that can bind siliceous materials are used.
This paper provides a summary on the study of the effectiveness of the binding characteristics of a blend of natural adhesive composed of tannin and cashew nut shell liquid (CNSL) on rice husk particleboards. The boards produced were subjected to mechanical and physical properties tests.
The results obtained have indicated that tannin-CNSL resin can be used to produce rice husk particleboards having good physical and mechanical properties if rice husk particles are crushed.
