Background and Objectives: The quantitative and qualitative data on urban solid waste is one of the essential steps in the scientific management of solid waste. The purpose of this study was to survey the qualitative and quantitative production of solid waste in Mashhad. Materials and Methods: In this descriptive study, in order to examine the quality of the samples, the separated materials we...
this paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. the properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...
A series of studies were conducted to investigate the effect of LCP inclusion on the processability of short glass fiber reinforced toughened nylon 6,6. The objective was to identify the role of each component phase and obtain composite synergism arising from a multi-component system. It was found that a hybrid composite offered superior processability over the glass fiber reinforced polymers a...
Separators are needed in microbial fuel cells (MFCs) to reduce electrode spacing and preventing electrode short circuiting. The use of nylon and glass fiber filter separators in single-chamber, aircathode MFCs was examined for their effect on performance. Larger pore nylon mesh were used that had regular mesh weaves with pores ranging from 10 to 160 mm, while smaller pore-size nylon filters (0....
اهمیت روز افزون ترموپلاستیک nylon - 66 بدلیل کاربردهای گوناگون آن در صنایع پلیمری مختلف همچون الیاف مورد استفاده در تایرسازی، نساجی، پوشاک ، فرش و قطعات مهندسی می باشد. متاسفانه نایلون 66 در ایران تولید نشده است و تماما وارداتی است . تلاش به منظور تولید صنعتی این پلیمر مهندسی در ایران کاملا توجیه اقتصادی دارد. در این پژوه سینتیک پلیمریزاسیون نایلون 66 مفصلا مطالعه است ، و با حل معادلات دیفرانسی...
