| چکیده | ||
| پرکنندههای معدنی از نظر مقداری دومین مواد مورد استفاده در کاغذسازی هستند که همواره تمایل زیادی به افزایش مقدار آنها برای بهبود خواص نوری و کاهش قیمت کاغذهای چاپ و تحریر وجود داشته است. در این تحقیق، برای افزایش مقدار پرکننده در کاغذ، سیلیکات کلسیم با روش رسوبگذاری درجا در الیاف رنگبری شدة باگاس بارگذاری شد. اثر دمای واکنش بر مقدار بارگذاری و رسوب سیلیکات کلسیم در سطح و داخل الیاف با استفاده از اندازهگیری میزان خاکستر، طیفسنجی XRD، تصویربرداری SEM و آنالیز EDX بررسی و تحلیل شد و در پایان، اثر این روش استفاده از پرکنندهها بر خواص فیزیکی و مقاومتی خمیرکاغذ بررسی شد. نتایج اندازهگیری خاکستر نشان داد که با روش استفادهشده سیلیکات کلسیم به خوبی در سطح و حفرات الیاف رسوب کرده است و با افزایش دمای واکنش، مقدار بارگذاری سیلیکات کلسیم در الیاف بیشتر شده است. طیف-سنجی XRD تشکیل رسوبات سیلیکات کلسیم و کربنات کلسیم را تاًیید کرد و تصویربرداری SEM نشان داد که مواد معدنی در سطح و در حفرات داخلی الیاف رسوب کردهاند. آنالیز EDX حضور عناصر سیلیس و کلسیم در الیاف تیمارشده را تاًیید و نشان داد ذرات معدنی رسوبگذاری شده در سطح الیاف ابعادی از 100 نانومتر تا 3 میکرون دارند. در یک گراماژ ثابت 80 گرم بر متر مربع، افزایش مقدار الیاف تیمارشده در کاغذ دستساز سبب افزایش روشنی و دانسیتة ظاهری و کاهش ماتی و مقاومتهای کاغذ شده است. | ||

| چکیده [English] | ||
| Mineral fillers are the second most important elements used in papermaking. Increasing filler content in writing and printing papers without decreasing the mechanical properties is always desired for enhancing the optical and printing properties and cost effective papermaking process. In this study, to increase the filler content in paper, calcium silicate was loaded by in situ precipitation on bleached bagasse fibers. The effect of reaction temperature on the loading and precipitation of calcium silicate on fibers was investigated using ash content measurement, XRD spectroscopy, SEM imaging and EDX analysis. Finally, the effect of treated pulp content on the physical and mechanical properties of pulp was investigated. Ash measurement results showed that calcium silicate precipitation in bleached bagasse fibers was achieved and the amount of calcium silicate loading increased with increasing the reaction temperature. XRD spectroscopy confirmed the formation of calcium silicate and calcium carbonate, and their precipitation in cell walls, lumen and interior spaces of the bleached bagasse fibers was confirmed by SEM imaging. The precipitated minerals on the fiber surface consisted of particles with various diameters. The EDX analysis confirmed the presence of silica and calcium in the treated fibers. With the constant basis weight of 80 g/m2, brightness and apparent density increased significantly, however the paper strength decreased by increasing the content of treated fibers in handsheet paper. | ||
