中文摘要 | 省產商用粒片板(T板及D板),進口之商用粒片板(A板)及中密度纖維板(N板)經不同濕度處理後,各試板之平均含水率隨處理濕度之增加而上升;其靜曲破壞強度,彈性係數,內聚力,木螺釘保持力均隨含水率之上升而下降,僅A板及N板浸水二小時者反而較C_8處理者(相對濕度90±2%,20℃,35天)之強度為高。而保釘力則以理想氣候(C_2)處理者為最高,試板之含水率上升或下降均促其保釘力減低。 |
英文摘要 | Domestic Particleboard type T and D, imported Particleboard type A and medium density fiberboard type N were treated by various humidities. The lower modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB) and screw holding strength values were obtained at high humidity, and the higher strength values were obtained at dry condition, but boar d type A and N immersed in water for two honrs had higher strength values than specimens which treated at 90±2% relative humidity (C_8 treatment). Board type T, D, A and N had, the highest nail holding strength at normal weather condition (C_2, relative humidity 62+2%, 20℃), in other words, humid and dry condition had the effect of reducing the nail holding strength. |
