中文摘要 | 本省高雄六龜產30年生臺灣杉,平均直徑25cm,比重0.365,生材含 水量184.87%,鋸製為3cm(厚)X16cm(寬)X180cm(長)之試材,並依鋸割順序使 每相鄰四片分屬不同之四組。以四種減濕乾燥基準進行試驗。結果顯示:3cm厚 臺灣杉板材可減濕乾燥至含水量10%以下;S-1基準(表 2)之效果較佳,其乾燥 速率約為0.50%MC/hr。 |
英文摘要 | The objective here was to develop a dehumidification drying schedule for 3cm Taiwania. 180cm in length, 25 cm in diameter, cut from two 25-year-old trees in Kaohsiung, southern part of Taiwan were used for this study. The bolts were then sawed into 3- by 15cm test boards. During cutting, each four consecutive boards were divided into four groups and sealed in plastic bags untill the time of drying. Each group of the test boards was dehumidification-kiln-dried by a different drying schedule (Table 2) from green to finaal moisture content of about 10%, and then compared primarily for drying rate and defects. Moisture content during was monitored by standard sample board technique. The results of this study indicated that: 1.Schedule S-1 (Table 2) can be efficiently applied to dry 3cm Taiwania lumber from green to 10 percent MC, and the drying rate is about 0.5% MC/hr.. 2.The relationship between MC and shrinkage is in a curvilinear correlation. 3.The local made dehumidification dry kiln is capable of drying 3cm Taiwania lumber to a final MC below 10 percent. |
