چکیده مقاله :
زمینه و هدف: با توجه به کمبود مواد اولیه برای صنایع لیگنوسلولزی، استفاده از ضایعات لیگنوسلولزی هرس درخت کنوکارپوس که کشت آن در کشور دلیل سرعت رشد قابل توجه و سازگاری با شرایط آب و هوایی کشور در حال گسترش می باشدکه می تواند مورد توجه قرار گیرد.روش بررسی: ضایعات کنوکارپوس پس از جمع آوری در سه گروه 1- برگ، 2- شاخه، و 3- شاخه-برگ تقسیم بندی شدند. سپس ترکیبات شیمیایی و ویژگی های مرفولوژی آنها سنجش شد. در ادامه این ضایعات از طریق روش سودا پخت شد و از خمیرکاغذ بدست آمده کاغذ دست ساز آزمایشگاهی ساخته شد و ویژگی های خمیرکاغذ و کاغذ حاصل مورد سنجش قرار گرفت.یافته ها: نتایج نشان داد که قسمت های مختلف ضایعات کنوکارپوس دارای خواص کاملا متفاوتی می باشند به طوریکه برگ با بیشترین درصد مواد استخراجی، لیگنین و خاکستر و کمترین درصد سلولز و همی سلولز، خمیرکاغذی غربال شده با بازده کم و عدد کاپای زیاد تولید نمود که به دلیل درجه روانی بسیار کم و زمان زهکشی خیلی زیاد، امکان ساخت کاغذ دست ساز را نداشت. در مقابل، شاخه با بیشترین درصد سلولز و همی سلولز و کمترین درصد مواد استخراجی، لیگنین و خاکستر، خمیرکاغذ غربال شده با بازده متعارف، درجه روانی زیاد و عدد کاپای کم، زمان زهکشی کم تولید کرد و خمیرکاغذ حاصل از ضایعات شاخه-برگ نیز حالت بینابینی داشت.بحث و نتیجه گیری: در مجموع در مقایسه با سایر مواد لیگنوسلولزی مانند باگاس و کاه گندم که به طور گسترده در صنعت خمیرکاغذ و کاغذ مورد استفاده قرار می گیرد، ضایعات شاخه-برگ درخت کنوکارپوس به دلایل ویژگی های کمی و کیفی بهعنوان ماده اولیه برای استفاده در صنایع خمیرکاغذ به صورت خالص مناسب نبوده و توصیه می شود که اختلاط آن با خمیر بازیافتی مورد بررسی قرار گیرد.
چکیده انگلیسی:
Background and Objective: Due to raw materials shortage for lignocellulosic industries, and cultivating Conocarpus erectus tree in the country due to its significant growth rate and adaptation to the country's climatic conditions, the use of its pruning residues can be considered as an alternative raw material.Material and Methodology: The Conocarpus erectus pruning residues were divided into three groups: 1- leaf, 2- branch, and 3- branch-leaf. Then the chemical composition and morphological properties were measured. Afterward, these residues were cooked by soda method and from the obtained pulps, laboratory handmade papers were made and to end, the properties of resulting pulps and the handmade papers were evaluated.Findings: The results showed that different parts of the Conocarpus residues have completely different properties, so that the leaves with the highest content of extractives, lignin and ash and lowest amount of cellulose and hemicellulose gave pulp with lowest screened yield and highest kappa number that was not suitable for paper production due to very low freeness and high drainage time. In contrast, the branch with the highest amount of cellulose and hemicellulose and lowest amount extractive materials, lignin and ash produced pulp with highest screened yield, freeness and lowest kappa number and drainage time. Also, in Compared to leaf- branch, pulp from branch produced paper with higher thickness, light scattering coefficient and tear but lower tensile and appear density.Discussion and Conclusion: In general, leaves and branches residue of Conocarpus compared to other lignocellulosic materials such as wheat straw and bagasse, which is widely used in the pulp and paper industry, due to qualitative properties reasons are not suitable in pure form for use in pulp and paper industries but are recommended to evaluation as the mixing with the recycled pulp.
