| مهم‌ترین چالش‌های استفاده از مواد معدنی و پرکننده در فرآیند کاغذ سازی ماندگاری کم و کاهش چشمگیر ویژگی‌های مقاومتی کاغذ می‌باشد. در این تحقیق با استفاده از الیاف بلند کرافت تجاری و نمک‌های آهن و با فرآیند سنتز درجا کاغذ مغناطیسی تولید شد. نانو اکسید آهن حاصل از سنتز درجا عملکردی مانند پر کننده‌ها دارد در نتیجه جهت جلوگیری از کاهش چشمگیر ویژگی‌های مقاومتی در کاغذهای مغناطیسی و کم بودن ماندگاری مواد در کاغذ نهایی، کیتوزان به عنوان افزاینده مقاومت و کمک نگهدارنده در سطوح 0، 10 و 15 درصد استفاده شد. ویژگی‌های کاغذهای مغناطیسی با میکروسکوپ‌های نیروی اتمی و الکترونی روبشی، پراش اشعه ایکس، مغناطیس سنج لرزشی نمونه مورد بررسی قرار گرفت. همچنین شاخص کشش و شاخص پارگی در نمونه‌های کاغذ مغناطیسی تعیین شد. نتایج حاصل از بررسی میکروسکوپی نشان داد که اندازه ذرات نانو مگنتیت در محدوده 1 تا 84 نانومتر بوده و مواد مغناطیسی کاملا سطح الیاف را پوشانده است. همچنین با افزایش مقدار کیتوزان درجه بارگذاری الیاف و اشباع مغناطیسی نمونه‌ها افزایش یافته به‌علاوه کاغذ مغناطیسی ساخته شده از خود خاصیت سوپر پارا مغناطیس نشان داده‌اند. نتایج بررسی ویژگی‌های مقاومتی کاغذ نشان داد که افزودن کیتوزان تا سطح 10 درصد سبب افزایش مقاومت به پارگی و کشش شده ولی افزایش آن تا سطح 15 درصد سبب کاهش این مقاومت ها شده است. | ||

| چکیده [English] | ||
| The most important challenges of using minerals and fillers in the papermaking process are low retention and sharp reduced paper strength properties. In this research, magnetic papers were synthesized using commercial kraft fibers and iron salts. Nano-iron oxide has the same performance as fillers, as a result, to prevent reducing strengths properties and retention of material in the final paper, chitosan uses as a strength agent and retention aid at 0, 10 and 15% levels. Characteristics of magnetic papers were investigated by atomic force microscope, scanning electron microscope, X-ray diffraction and vibration sample magnetometer. Tensile index and tear index were also determined in magnetic paper samples. The results of the microscopic examination showed that the magnetite nanoparticles were in the size range of 1 to 84 nm and the magnetic materials completely covered the fibers surface. Also, increasing chitosan content, increased the degree of loading and magnetic saturation of the samples. The magnetic paper samples had super para magnetic behavior. The results showed that adding chitosan at 10% increased tear and tensile strength but 15% chitosan decreased the strengths properties of magnetic paper. | ||
