Conversion of high-value panel products from less-used wood species Malaysia

Razali A.K., . and Paridah M.T., . (1992) Conversion of high-value panel products from less-used wood species Malaysia. [Proceedings Paper]

A few of the less-used indigenous tropical hardwood species have been investigated for conversion into various panel products by the Forest Products Laboratory of the Faculty of Forestry Universiti Pertanian Malaysia. The main objective of the study is to upgrade the use of the less-used or the so-called low-grade species because of their small diameter and lower density. The conversion into composite panel products seems appropriate since the desired compression ratio i.e. board density/raw material density could be obtained resulting in acceptable physical and mechanical board properties. Mallotus macrostachys Balik angin Anthocephalus chinensis Kelempayan Macaranga pruinosa Mahang and Bombax valetonii Kekabu utan have been converted into particleboards and/or medium density fibreboards MDF with final densities ranging from 400 - 750 kg/m3. Both formaldehyde-based and formaldehyde-free resin adhesives were used as binders. The results obtained after testing the conditioned boards indicated that low to medium density composite boards of high quality could be manufactured with acceptable technical and commercial grades meeting the Japanese Industrial Standards JIS for general uses. In addition panels with proper preservative treatments could also be utilised in semi-structural applications. Nonetheless it is recommended that water repellents such as wax emulsion should be incorporated during the manufacture of the panels to increase their water resistance

Abstract

A few of the less-used indigenous tropical hardwood species have been investigated for conversion into various panel products by the Forest Products Laboratory of the Faculty of Forestry Universiti Pertanian Malaysia.

The conversion into composite panel products seems appropriate since the desired compression ratio i.e. board density/raw material density could be obtained resulting in acceptable physical and mechanical board properties. Mallotus macrostachys Balik angin Anthocephalus chinensis Kelempayan Macaranga pruinosa Mahang and Bombax valetonii Kekabu utan have been converted into particleboards and/or medium density fibreboards MDF with final densities ranging from 400 - 750 kg/m3.
