| چکیده | ||
| در این تحقیق، تأثیر استفاده از پرکننده کربنات کلیسم رسوبی بههمراه نانوسلولز بهعنوان مقاومتدهنده جهت جبران کاهش مقاومتهای کاغذ تهیهشده از خمیرکاغذ باگاس مورد بررسی قرارگرفت. سوسپانسیون نانوسلولز با خشکی 1/0 درصد یکنواختشده با فراصوت به مقدار 2 درصد بر مبنای وزن خشک الیاف به خمیرکاغذ دارای 15 درصد پرکننده کربنات کلسیم اضافه شد و با همین نمونه بدون نانوسلولز و خمیرکاغذ پایه (بدون هرگونه افزودنی) مورد مقایسه قرارگرفت. کمک نگهدارنده پلیاکریل آمید کاتیونی به میزان ثابت 14/0 درصد بر اساس وزن خشک الیاف استفاده شد. تحلیل آماری نتایج نشان داد که با افزودن سامانه PCC و نانوسلولز به سوسپانسیون خمیرکاغذ باگاس، زمان آبگیری افزایش یافت. اضافهشدن نانوسلولز بهعلت تشکیل کلوخههای چسبنده، ماندگاری ذرات پرکننده را افزایش دادهاست. تصاویر الکترونی تهیهشده از نمونههای کاغذ نیز دلمهشدن ذرات پرکننده، ماندگاری بیشتر پرکننده و پراکندگی بهتر آن در شبکه کاغذ را تأیید میکند. بهعلاوه، در کاغذهای پرشده با PCC و نانوسلولز با ماتی و روشنی تقریباً مشابه، بطور معنیداری افت خواص مقاومتی ناشی از اضافهشدن پرکننده جبران شدهاست. گرچه زمان آبگیری بهنسبت زیاد از این خمیرکاغذ یک محددویت اساسی است، ولی پیشتیمار پرکننده با نانوسلولز قبل از اضافهشدن آن به خمیرکاغذ میتواند بهعنوان یک راهکار امیدوارکننده مورد بررسی قرار گیرد. | ||

| In this research, the effect of adding precipitated calcium carbonate filler combined with nanocellulose as reinforcement was examined to compensate the strengths loss of papers made of bagasse pulp. About 2 % of nanocellulose based on oven dry fibers suspended in water with 0.1 % consistency homogenized by ultrasonic was added to the pulp having 15 % PCC filler and was compared with the same sample without nanocellulose and base pulp (without any additives). Cationic polyacrylamide retention agent was added to the pulp suspension at the constant level of 0.14 % based on oven dry fibers. Statistical analysis of results revealed that the drainage time increased by adding of PCC and nanocellulose system to the bagasse pulp suspension. Addition of nanocellulose has enlarged filler particle retention due to the formation of adhesive flocs. Prepared SEM images from paper samples confirm filler particles flocculation, larger filler retention and their better distribution in paper network. Moreover, in papers filled by PCC and nanocellulose with roughly equal similar opacity and brightness, loss of strength characteristics due to adding of filler has been compensated. Although relatively higher drainage time of this pulp suspension is a substantial limitation, but pretreatment of filler with nanocellulose prior to its addition to the pulp can be investigated as a promising alternative. | ||
