中文摘要 | 本研究旨在探討小徑木為原料製造定向粒片板之可行性及改良其材質的方法。試驗結果列舉如下:(1)單層構造之定向粒片板(O. P. B.)和傳統粒片板(R. P. B.)比較時不論M. O. E.或M. O. R.均合日本工業規格200 type,且以定向粒片板為大,其比為M. O. E. 2.8倍,M. O. R. 2.3。(2)定向立片板不論常態或濕潤狀態之M. O. E.及M. O. R.均為定向方向(//)>垂直方向(⊥)(M. O. E. // : ⊥ =9:1, M. O .R. //:⊥=7:1)(3)三層構造定向粒片板固然有增大M. O. E.及M. O. R.之效果,但中層必須維持能抵抗剪應力最低密度。(4)定向粒片板之表面貼以旋切單板有助於提高M. O. E.及M. O. R.,與未貼面之定向盹片板比較時,M. O. E.為1.5~1.6倍,M. O. R.為1.3~1.6倍;與傳統式粒片板比較時M. O. E.為4.2~4.7位,M. O. R.為3.0~3.9倍。(5)三明治構造材料之彎曲M. O. E.的計算式[Et/Ec=r/1-(r/1-1)α^3]可適用於三層構造定向立片板。(6)內聚強度:本研究製造之所有粒片板的內聚強度在3~4 kgf/cm^2,均合日本工業規格200 type。(7)單層構造之定向粒片板和傳統式粒片板之木螺釘保持力41~48 kgf均合日本工業規格150 type。而三層構造之定向粒片及單板貼面粒片板之木螺釘保持力均合日本工業規格200 type。(8)吸水厚度膨脹率,雖略為偏高,可藉添加石臘改善之。 |
英文摘要 | The feasibility of making oriented particleboard from small logs and method of upgrading boards properties were studied. Three kinds were 'made in our pilot plant :(A ) Single layered oriented particleboard ( O. P. B. ) and traditional random particleboard ( R. P. B. ) from small diameter Sugi particles. (B) Three layered oriented board composed of denser Mizunara particles on the face layers and small diameter Sugi particles in the middle layer. (C) Veneer overlaid oriented particleboard from Sugi particles. Results of the tested properties are: 1.Modulus of elasticity (M O E ) or Modulus of rupture (M O R) of both O. P. B. coincide with the 200 type of Japan Industrial Standard (J I S), O. P. B. is , however, superior, the ratios are 2.8 and 2.3 respectively. 2 M O E and M O R of oriented particleboard in oriented direction (//) are greater than those in perpendicular direction (⊥) ( MOE // : ⊥=9 : 1 ; M O R // : ⊥=7:1) , no matter the boards are under normal or wet condition. 3. Three layered oriented particleboard benefits from M O E and M O R increase, while middle layer maintains some density to develop shear strength. 4. The overlaying of rotary veneer on the surface of O. P. B. increases the MOE and MOR of particle-board. The ratio of with and without veneer overlay is 1.5 -1.6 for MOE and 1.3 -1.6 for M O R. Comparing to R. P. B., the ratio is 4.2 - 4.7 and 3.0- 3.9 respectively. 5. Equation [Et/Ec=r/1-(r/1-1)α^3]for calculating the MOE in bending of sandwiched structural material could be applied to three layered O. P. B. . 6. Internal bonding strength(I. B. ) : All particleboards manufactured in this study develop an internal bonding strength at 3-4 kgf/cm^2, coincide with the requirement of 200 type J. I. S. 7. The screw holding strength of O. P. B. and R. P. B. reach 41-48 kgf, coincide with JIS 150 type and that of three layered O. P. B. and veneer-over-laid particleboard coincides with JIS 200 type. 8. Though the thickness swelling ratio under absorption test is slightly higher, it can be retarded by paraffin addition. |
