Abstract

Leaching test of rubber wood treated with boric acid 1%, 1% mixture of boric acid and borax, 1% mixture of boric acid and furfuryl alcohol and 1% mixture of boric acid + borax + furfuryl alcohol were determined according to American Wood Preservation Association Standard (AWPA) E1-06 and the British Standard Method (BS 5688: Part 1) The results of the most amount of boric acid leachate in the first leaching was found in rubber wood treated with 1% boric acid (average 0.4361%). Following by rubber wood treated with 1% mixture of boric acid and borax, 1% mixture of boric acid + borax + furfuryl alcohol and 1% mixture of boric acid and furfuryl alcohol which average leaching were 0.4035, 0.3590 and 0.3354, respectively However, the leaching procedure was carried on for a times. Then the total amount of boric acid leached from treated wood was analyzed. The results of the most leaching of boric acid was found in rubber wood treated with 1% mixture of boric acid and borax (average 1.7270%), following by rubber wood treated with 1% boric acid, 1% mixture of boric acid and furfuryl alcohol and 1% mixture of boric acid + borax + furfuryl alcohol which average boric acid leachate were 1.5147, 1.3130 and 1.2567, respectively. The results from this experiment found that furfuryl alcohol could diminish the leaching of boric acid from treated rubber wood effectively.
