| Summary: | Kesan pengadunan dan pengolahan terhadap sifat-sifat gentian,
mekanikal dan optikal pulpa telah dikaji dengan melakukan perbandingan di
antara jenis-jenis pulpa iaitu pelepah kelapa sawit (OPF), tandan buah kelapa
sawit kosong (EFB), Acacia mangium dan kayu lembut Genis pine). Kesan
pengadunan pulpa memberi kesan yang positif terhadap peningkatan kekuatan
kertas dengan pengggantian gentian-gentian individu yang kuat terhadap
gentian-gentian yang lemah. Penambahan pulpa serendah 20% boleh memberi
keputusan yang memberangsangkan.
The blending and treatment (beating) of pulps derived from oil palm frond
(OPF), empty fruit bunch (EFB), Acacia mangium and soft wood (pine type) were
investigated as means of modifying the mechanical, optical, and fibers
characteristics of the resulting paper. The strength of paper produced from
weaker pulps was significantly increased by blending with as little as 20% of the
stronger OPF and EFB pulps. |
