  1. USING Acaciamangium AS A SINGLE RAW MATERIAL IN PRODUCING PARTICLEBOARD Presented by VICTOR PALLICKAL XAVIER

  2. AIM This research focus on using Acaciamangium as a single raw material in producing particleboard.

  3. CONTENTS • Introduction • Research Objectives • Materials and Methods • Results and discussion • Conclusions and Recommendations • Publications

  4. INTRODUCTION • Wood industry in Malaysia • Wood composite products • Particleboard industry outlook in Malaysia • Demand and usage of particleboard • Demand for raw material

  5. Malaysian particle board Industry Overview Source: The 8th Meeting (July 7th, 2006)Thailand–Malaysia–Indonesia Particleboard Manufacturers Kuala Lumpur, Malaysia

  6. Justification • The tropical forest will be disappearing at the rate of 15-20 million ha/year • All wood industries in Malaysia is getting a serious problem on getting the raw materials. • Plantation species as a raw material for future.

  7. Objectives • To study the physical and mechanical properties of particleboard using A. mangium as a raw material • To compare the physical properties of A.mangium particleboard to mixed wood particleboard • To compare the mechanical properties of A.mangium particle board to mixed wood particleboard

  8. Why I choose A.mangium ? • Acacia mangium is a fast-growing and evergreen species. • Extremely vigorous growth (annual wood volume increment of over 30 cubic meters per hectare on favorable sites) • A.mangium falls under the light hardwood classification with mechanical properties MOR (modules of Ruptures): 74.5N/mm2 MOE (Modules of Elasticity ): 9908N/mm2

  9. Relative freedom from diseases • Adapted to a wide range of acidic soils (pH 4.5-6.5). • Rotation years is very small and Available plenty in Sabah.

  13. Sampling • Acacia logs were extracted from Paitan forest plantation in Kudat, Sabah • The age of A.mangium used is between 6-8 years. • While mixed hardwood like Shorea spp., Dryobalanops spp., and other timbers (O.T) were obtained from neighboring sawmills and plywood mills such as Sri Jambongan and Seraya Sawmill.

  21. Bending Strength Comparison between Unsanded A.mangium and Mixed Hardwood Boards

  22. Internal Bond Comparison between Unsanded A.mangium and Mixed Hardwood Boards

  23. Surface Bond Comparison between Unsanded A.mangium and Mixed Hardwood Board

  24. Screw Holding Comparison between Unsanded A.mangium and Mixed Hardwood Boards

  25. Density Comparison between Sanded A.mangium & Mixed Hardwood Board

  26. Thickness Swelling Comparison between sanded A.mangium and Mixed Hardwood Boards

  27. Bending Strength Comparison between Sanded A.mangium and Mixed Hardwood Boards

  28. Internal Bond Comparison between Sanded A.mangium and Mixed Hardwood Boards

  29. Surface Bond Comparison between Sanded A.mangium and Mixed Hardwood Boards

  31. ANOVA REULTS Physical properties of unsanded A.mangium and mixed wood particleboard Analysis P-value Density 0.004(*) Swelling(2hrs) 0.559(n.s) Swelling (24hrs) 0.787(n.s) *Significant n.s= Non Significant

  32. Cont… Mechanical properties of unsanded A. mangium and mixed wood particle board Analysis P-value Bending strength 0.001(*) Internal bond 0.512 (n.s) Surface bond 0.169 (n.s) Screw holding 0.014(*) *Significant n.s= Non Significant

  33. Cont… Physical properties of Sanded A.mangium and mixed wood particleboard Analysis P-value Density 0.001(*) Swelling(2hrs) 0.197(n.s) Swelling (24hrs) 0.832(n.s) *Significant n.s= Non Significant

  34. Cont… Mechanical properties of Sanded A. mangium and mixed wood particle board Analysis P-value Bending strength 0.001(*) Internal bond 0.199 (n.s) Surface bond 0.072 (n.s) Screw holding 0.016(*) *Significant n.s= Non Significant

  35. CONCLUSIONS • The physical and mechanical properties of the particle board produced from A. mangium proved that A.mangium can be used as a single raw material in producing particle board. • The physical properties of the mixed wood and A. mangium, A. mangium have lower density compare with the mixed wood and the swelling properties are almost the same.

  36. Cont… • The mechanical properties of A. mangium and mixed wood, A. mangium have better bending strength and screw holding compare to mixed hardwood particle board and in terms of the surface bond and the internal bond the properties are almost the same.

  37. Contributions of the study • This research has successfully proved that Acacia mangium can be an option in particleboard industry especially in Sabah. • The study states that A.mangium can be used as a single raw material for making particle board • It prove that particle board produced from A.mangium can be compete with particle board produced from other species as a raw material • A step towards utilizing the A.mangium fully from the plantation
