چکیده

امروزه پلی وینیل کلرید (پی وی سی) در صنعت خودرو سازی، تولید کف پوش ها و نما های ساختمانی، انواع لوله های آب و فاضلاب، مدارهای الکترونیکی و ... مورد استفاده قرار می گیرند. با در نظر گرفتن ویژگی زیست تخریب ناپذیر بودن پلیمرها، محصولات پی وی سی مصرف شده به عنوان ضایعات پلیمری تولید و انباشته می شوند. یکی از روش ها برای بازیافت پلیمر ها با کمترین تخریب ساختار شیمیایی، استفاده از اصلاح سطح پلاسمایی است. در این تحقیق تاثیر پلاسمای هگزا فلورید سولفور روی سطح پی وی سی مصرف شده بازیافتی در زمانها و فشار های مختلف بررسی شده است . بهترین زمان پرتودهی برای بدست آوردن سطح آب گریز 5 و 10 دقیقه در فشار 16/0 تور محفظه فرآیند پلاسما بدست آمد که در این حالت زاویه تماس° 101حاصل شد. آنالیز مقاومت الکتریکی سطح نشان داد که اصلاح سطح نمونه های پی وی سی به وسیله پلاسما SF6، در فشار و زمان معین، باعث افزایش مقاومت الکتریکی سطح آنها می شود.

چکیده [English]

Today, polyvinyl chloride (PVC) is used in the automotive industry, production of flooring and building facades, water and wastewater pipes, electronic circuits, etc. Considering the non-biodegradability of polymers, PVC products are produced and accumulated as polymer waste. One of the methods for recycling polymers with minimal destruction of chemical structure is the plasma treatment. In this study, the effect of hexafluoride sulfur plasma on recycled PVC at different times and pressures is investigated. The best exposure time was obtained a 5 and 10 minute for possess a hydrophobicity surface at a pressure 0/16 torr of the plasma processing chamber, in which case the contact angle was 101 °. The electrical resistivity analysis showed that modifying the surface of PVC samples by plasma Sulfur hexafluoride at a certain pressure and time would increase the electrical resistance of their surface.
