中文摘要 | 本研究之目的在改善國產粒片板之品質,同時降低其成本,將泡桐、 油桐邊皮材所製得之粒片,在15、30、50%之重量混合百分比之下,分別與國產 粒片板之原料(廢料粒片)混合製造粒片板,並在各混合百分比下,降低粒片板之 比重。試驗結果歸結如下: 1.在各混合百分比下,粒片板之抗彎強度隨板比重之降低而直線下降,並且在相 同比重時,混合百分比愈大,其抗彎強度愈大。 2.除了泡桐混合百分比50%之外,內聚力隨板比重降低而減小,在相同比重之下 ,內聚力受混合百分比增減之影響不顯著。 3.厚度膨脹率隨板比重或混合百分比之降低而減少。 4.國產粒片板中,混入30%之泡桐或油桐粒片,比重降至0.65並與比重 0.72之 國產粒片板比較時,其抗彎強度與內聚力,可獲得令人滿意之結果,而厚度膨脹 率則否。 |
英文摘要 | The purpose of this experiment is to study the possibility of improving board quality and, at the same time, reducing production cost in a particl- eboard mill. We mixed the particles made from slabs of P. sp. and A. sp. into the wood residues particle by weight in three ratios, i.e. 15%, 30%, and 50%. We also reduce the sp. gr. of particleboard in each mixed ratio. Results obtained are as follows: 1.In each mixed ratio, the bending strength of particleboard are obviously decreased when its sp. gr. is lowered. The bending strength is improved by the increase of mixed ratio in the same sp. gr.. 2.Internal bond strength are lowered with reducing sp. gr. of particleboard, except mixing 50% particle of P. sp. into wood residues particle. In the same sp. gr., those strength are not significantly affected by the fluct- uation of mixed ratio. 3.The thickness swelling results are reduced when the sp. gr. or mixed ratio is lowered. 4.When we mixing 30% particle of P. sp. or A. sp. into domestic particleboard and reducing the sp. gr. from 0.72 to 0.65, the bending strength and internal bond strength show satiafactory results, but not the thickness swelling results. |
