中文摘要 | 以柳杉、台灣泡桐及木油桐為原料,並以尿素甲醛樹脂為膠合劑(用膠量7%),製造長薄片型與方薄片型粒片板。原料密度低者,以製造低密度之片板較為宜。長薄片型粒片板之靜曲破壞強度大於方薄片型粒片板約9.77%。而此兩種型態粒片板之螺絲釘保持力、厚度膨脹率及吸水率差異不明顯。以應力設計時儀之非破壞性測定法,所得之彈性係數,除柳杉粒片板之密度在0.6g/cm^3以上之外,大致以長薄片型粒片板之彈性係數大於方簿片型粒片板。 |
英文摘要 | The Cryptomeria, .Taiwan Paulownia and Wood Oil Tree were used as raw materials and the Urea formaldehyde resin was .used as adhesive (glue level 7% based on oven dried weight of particles), to make flakeboard and Waferboard. The low density raw material was more suitable to produce low density particeboard. The modulus of ruputure of flakeboard was approximately 9-77% higher than the waferboard, but the screw holding strength, thickness swelling and water absorption of this two types of particleboard showed insignificant difference'. The modulus of elasticity (MOE), tested by tress-wave-timer of nondestructive method, showed that the MOE of flakeboards have higher than the waferboards, besides those particleboards made by cryptomerta with density larger than 0.6g/cm^3. |
