Effect of Beating Process to Soda Anthraquinone Pulp of Oil Palm Male Flower Spikes Fibre

Abstract

Abstract. This study was carried out to investigate the effect of beating process to the characteristics of pulp and paper produced from oil palm oil male flower spikes (OPMFS). OPMFS pulp was prepared according to chemical Soda-AQ pulping process. 60 gsm handsheet of oil palm male flower spikes paper were prepared from OPMFS pulp with four different beating times which are 0 revolution, 1000 revolutions, 2000 revolutions and 3000 revolutions. All physical and mechanical characteristics were investigated according to TAPPI and MS ISO standards. The results show that overall physical and mechanical characteristics of POMFS paper were influenced and enhanced by beating process between 0 until 3000 revolutions. This research demonstrate some potential characteristics of palm oil male flower spikes (OPMFS) paper to be investigated as a newly explored non-wood based raw material for papermaking raw material for papermaking.

Characteristics of Linerboard and Corrugated Medium Paper Made from Durian Rinds Chemi-mechanical Pulp

“…The results show that durian rinds CMP is comparable with other types of raw materials for papermaking. However, mechanical treatments such as beating or refining is recommended for unbeaten durian rinds CMP pulp in order to enhance the pulp and paper characteristics [5,11,24]. Table 4 shows that RCT results of durian rinds 120 gsm linerboard and corrugated medium made from CMP pulp are comparable with other paper types and commercial linerboards.…”

“…In short, the paper and paperboard industries in Malaysia utilize imported virgin long-fiber pulp and secondary fibers, such as the old corrugated container (OCC) and waste papers to produce packaging papers [5]. In order to reduce the dependence on imported pulps, various researches have been conducted on the utilization of agricultural wastes as raw material alternatives for packaging paper such as kenaf [1, 2,6], coir [5], oil palm empty fruit bunch [7,8], Semantan bamboo [9] and oil palm male flower spikes [10,11]. Malaysia has an abundance of agro waste materials which have not been fully utilized [12].…”

Effects of Beating on the Characteristics of Malaysian Durian (Durio Zibethinus Murr.) Rind Chemi-Mechanical (Cmp) Pulp and Paper

“…In beating process, a laboratory PFI mill machine located at Pulp and Paper Laboratory in the Forest Research Institute Malaysia (FRIM) used to beat the screened pulp according to TAPPI T-248 "Laboratory Beating of Pulp (PFI mill method)" up to three different beating revolutions which are 1000 revolutions, 2000 revolutions and 3000 revolutions similar to Masrol et al [35]. The low beating revolutions were chosen due to the low level of freeness and drainage time by the unbeaten durian rind CMP pulp.…”

“…The improvement of the fiber flexibility due to beating process causing fibers to easily collapse during the paper making process and contributes to higher fiber-to-fiber bonding [34]. A recent studies by Masrol et al [35,36] also shows soda-AQ oil palm male flower spikes characteristics were enhanced by the beating process.…”

Effects of Total Chlorine Free (Tcf) Bleaching on the Characteristics of Chemi Mechanical (Cmp) Pulp and Paper From Malaysian Durian (Durio Zibethinus Murr.) Rind

“…Hence, research and developments of several non-wood-based raw materials for pulp and paper have been undertaken rapidly by researchers in Malaysia. Several studies have utilised Malaysia's huge oil palm industry residues such as empty fruit bunch (EFB) [3][4][5], oil palm fronds [6][7][8][9] and oil palm male flower spikes (OPMFS) [10,11] [17][18][19] as non-wood based raw material for pulp and paper industry.…”
