Glue Spread On Properties Of Oil Palm
Trunk Laminated Veneers.
Masters thesis, Universiti Sains Malaysia.
Abstract
Kajian terhadap penghasilan venir terlaminasi (LV) daripada batang kelapa
sawit (OPT) semakin meningkat selaras dengan tujuan untuk mengurangkan
bahan buangan daripada keJapa sawit. Walau bagaimanapun, kajian
terhadap penggunaan perekat bertekanan sejuk ke atas kekuatan ricih,
kekuatan ikatan, pengeeutan dan pengembangan terhadap venir terlaminasi
daripada OPT masih kurang diberi perhatian. Objektif utama kajian ini
adalah untuk mengkaji sifat-sifat fizikal dan mekanikal LV yang dihasilkan
daripada venir OPT dengan menggunakan beberapa jenis perekat
bertekanan sejuk iaitu Emulsion polymer isocyanate - copolymer Vinyl
acetate (EPI-Vae), Emulsion polymer isocyanate - copolymer Styrene
butadiene rubber (EPI-SBR) dan Polyvinyl acetate (PVAe).
Researches on Laminated Veneer (LV) manufactured from oil palm trunk
(OPT) veneers are being developed in line to reduce waste from oil palm
biomass. However, there was little information available concerning the·
effects of adhesives types on tensile shear strength, bonding, shrinkage and
swelling of these laminated products from oil palm. The objective of this study
was to investigate some of the properties of LV made from OPT using cold
setting adhesives namely Emulsion polymer isocyanate - copolymer Vinyl
acetate (EPI-VAc), Emulsion polymer isocyanate - copolymer Styrene
butadiene rubber (EPI-SBR) and Polyvinyl acetate (PVAc).
