中文摘要 | 本研究之目的在於將已被社會大眾視為農業廢棄物之花生殼回收再有效利用成現今社會普遍使用之粒片板商品,使用酚甲醛樹脂(PF)作為本研究之主要應用粒片膠合劑。板密度設定為0.65 g/cm^3,製板壓力、時間和溫度分別設定為2.74 MPa、8 min和190℃,板材尺寸為450 mm× 450 mm× 10 mm。以一組使用尿素甲醛樹脂(UF)之花生殼粒片板材料與使用酚甲醛樹脂之花生殼粒片板相互比較其甲醛之釋出量。於佈膠方面,UF及PF之使用量分別為花生殼粒片之10%與6%。因為花生殼粒片板之自身強度較低,故本研究之主要方針乃為將其強化,使花生殼粒片板性質符合CNS 2215-2006之標準,並被社會大眾所接受。其強化材料分別使用混合不同比例之木粒片和面層處理。其面層處理依材料之性質有表底層強化與表中底層強化之探討。其面層材料分別為紅柳桉木單板、孟宗竹旋切單板及孟宗竹之編織竹單板。本研究之試驗組合分為15組不同類型結構之複合材,並以鄧肯(Duncan)檢定其中性質之差異顯著性。因本研究之實驗組均使用PF作為膠合劑,故實驗組均符合CNS 2215-2006 F3級甲醛釋出量之標準,而經面層強化之處理材料,依試驗性質之不同,分別符合CNS 2215-2006之8型、13型和18型之標準。本研究證實,經混合不同比例之木粒片及使用面層強化處理後之花生殼粒片板,其力學性質均有提高之效果。花生殼粒片板物理性質方面,密度,含水率,吸水厚度膨脹率之數值分別介於0.60~0.63 g/cm^3, 3.35~4.71%和12.74~42.30%。花生殼粒片板添加木粒片後,其吸水厚度膨脹率會隨著木粒片的增加而增加。力學強度方面,內聚強度,木螺絲保持力,抗彎強度,彈性模數,濕潤抗彎強度之數值分別介於0.075~0.64 MPa,198.51~526.42 N,3.05~34.08 MPa,277.91~3212.61 MPa和1.33~21.45 MPa。 |
英文摘要 | The purpose of this study was to improve the strength of particleboard(made from agricultural residues, such as peanut husk)by using different wood-based materials. The board size, target density and types are 450 mm × 450 mm × 10 mm, 0.65 g/cm^3, 15 respectively. The binder was phenolic formaldehyde resin (PF). The resin content of PF is lower (i.e.6%) than commonly used in UF (i.e.10%). Pressing temperature, pressure and time are 190℃, 2.74 MPa, 8 min respectively. As the low bending strength of particleboard made from peanut husk, we used different kinds of wood-based materials such as radiata pine particles, red lauan veneer, bamboo veneer etc. to increase the mechanical properties. Free formaldehyde emission of the boards ranged from 0.71 to 1.41 mg/L (meets F3 of CNS 2215-2006). Board density, moisture content and thickness swelling were 0.60~0.63 g/cm^3, 3.35~4.71%, 12.74~42.30% respectively. In mechanical properties, board internal bond strength, screw holding strength, bending strength, modulus of elasticity and wet bending strength were 0.075~0.64 MPa, 198.51~526.42N, 3.05~34.08 MPa, 277.91~3212.61 MPa, and 1.33~21.45 MPa respectively. |
