Abstract

Enhancing mold-resistance of laminated bamboo curtain lumber using three non-native bamboo species.

Abstract

Laminated bamboo curtain lumber (LBCL) was manufactured from Dendrocalamus hookeri, Bambusa teres, and Yushania alpina all from Nepal or Ethiopia, and was coated with commercial mold inhibitors, 3-iodo-2-propynyl butyl carbamate (IPBC), Tung oil, or nitro-cellulose lacquer to improve anti-mildew capabilities. In the laboratory, resistance of both coated and uncoated LBCL to blue-stain and mold fungi was evaluated using China National Standard GB/T 18261-2000. Results showed that the uncoated LBCL had no anti-mildew capabilities according to areas of mold infection. Bamboo species had little influence on mold resistance with LBCL (P<0.05); whereas, treatment methods had a strong effect on the mold resistance (P<0.01). LBCL made of B. teres had slightly better resistance to Botryodiplodia theobromae than the other two bamboo species (P<0.05), but LBCL coated with 3% IPBC and lacquer was basically resistant to B. theobromae and Trichoderma lignorum. The most effective treatment method that was an LBCL with 5% IPBC and lacquer coating provided 100% resistance to B. theobromae and T. lignorum was the most effective.
