Optimization of the Strength Properties of Waste Oil Palm (Elaeis Guineensis) Fronds Fiber

ABSTRACT

In this study, Box-Behnken design (BBD) and response surface methodology (RSM) was applied to study the effects of alkaline peroxide treatment variables (cooking time, sodium hydroxide concentrations, and hydrogen peroxide concentrations) on the pulp and paper strength properties (screened pulp yield, kappa number, tensile index, tear index, burst index), which are considered dependent variables or response variable of the extracted cellulose from oil palm (Elaeisguineensis) fronds (OPF) vascular bundle fibers. The results indicated that at the optimum operating conditions of 2.35% NaOH, 5.00% H₂O₂ and a 53.41 min cooking time, resulting maximum strength properties (tensile index, burst index, tear index,) gave 9.92 Nm/g, 6.55 KPam²/g, 6.22 mNm²/g, respectively. The study revealed that alkaline peroxide pulped fibers of oil palm frond vascular bundles could be considered a suitable alternative for paper qualities with moderate strength requirements.

摘要

在本研究中，使用 Box-Behnken 设计（BBD）和响应表面法（RSM）来研究碱性过氧化物处理变量（蒸煮时间、氢氧化钠浓度和过氧化氢浓度）对纸浆和纸张强度性能（过滤的纸浆产量、卡伯值、拉伸指数、撕裂指数、破裂指数）的影响，后者被视为从油棕（Elaeisguineensis）叶（OPG）维管束纤维提取的纤维素的因变量或响应变量。结果表明，最佳操作条件为2.35%浓度氢氧化钠、5.00%浓度过氧化氢和 53.41 分钟蒸煮时间，此条件下可得到最大强度性能（拉伸指数、爆裂指数、撕裂指数分别为 9.92 Nm/g、6.55 KPam²/g、6.22 mNm²/g）。研究表明，油棕榈叶维管束的碱性过氧化物制浆纤维可视为具有中等强度质量要求的纸张的合适替代品。
