桂竹熱處理及應用

Thermal Treatment of Makino Bamboo and its Utilization

為發展抗水及抗黴菌之家庭用精緻桂竹器，對熱處理及抗黴菌化學處理過程必需有一定之認知。試驗結果顯示，桂竹茶杯及茶筒經120 ℃ 高溫水蒸汽熱處理30 分鐘後，再以5 % KH-02 防黴劑煮30 分鐘，可得具不錯防黴及抗水性之桂竹茶器。殘留在竹器內之防黴劑可經30 分鐘熱水煮沸，輕易除去。此外，在竹茶筒外部繪製美麗國畫，並塗以耐候性佳之polyurethane 漆，可提升桂竹之利用價值。 For the development of a water-resistant and anti-mold makino bamboo household utensils, the optimum thermal treatment and anti-mold chemical process must be known. Experimental results revealed that heating makino bamboo utensils (tea-cup and tea-container) at 120 ℃ steam for 3 hours and then dipping in boiling 5% KH-02 water solution for 30 minutes, molds are nearly avoidable and waterresistance can be attained. The residual mold-resistance chemicals in bamboo utensils can be removed effectively in boiling water for another 30 minutes. In addition, it becomes evident that coating polyurethane onto the surface of light brown carbonized bamboo tea-container with Chinese painting on we devised may enhance the utilization of makino bamboo to some extents.
