[ 1 ] - تجزیه کاتالیستی مخلوط ضایعات پلیمری به محصولات میان تقطیری با استفاده از کاتالیست جدید AIT100
شکست کاتالیستی بعنوان بهترین جایگزین برای بازیافت ضایعات پلاستیکی محسوب می شود. بر همین اساس تبدبل مخلوط پلیمرها ( پلی اتیلن سبک و سنگین، پلی پروپیلن، پلی استایرن، پلی اتیلن ترت فتالات و پلی وینیل کلراید ) در حضور کاتالیست100 AIT و تبدیل به محصولات هیدروکربوری سبک مورد بررسی قرار گرفت. در این کار مخلوط پلاستیک ها براساس ترکیب درصد سازمان بازیافت به منظور نزدیک بودن به واقعیت استفاده شده است. هم...
[ 2 ] - Nanocomposite Coating Based on Thermoplastic Acrylic Resin and Montmorillonite Clay: Preparation and Corrosion Prevention Properties
Different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. The coatings were applied on low carbon steel plates. Optical microscopy, sedimentation test, transmission electron microscopy, and X-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. The corrosion resistance of coatings was evaluated by electrochemical...
[ 3 ] - Preparation and Characterization of Structure and Corrosion Resistivity of Polyurethane /Montmorillonite/Cerium Nitrate Nanocomposites
In this study, nanocomposite coatings based on polyurethane cerium nitrate montmorillonite (MMT) were prepared, applied on carbon steel substrates, and investigated. The nanocomposite coatings were successfully prepared by the effective dispersing of nanoparticles in polyurethane resin by mechanical and sonication processes. The state of dispersion, dissolution, and incorporation were character...
[ 4 ] - Evaluation of the Effects of Nanoclay Addition on the Corrosion Resistance of Bituminous Coating
In this study, the corrosion resistance of a bituminous coating reinforced with different ratios of nanoclay pigment was studied. To make nanocomposite coatings, 2, 3, and 4 wt.% of clay (Cloisite Na+) were incorporated into water emulsified bitumen. The coatings were applied to steel 37. Optical microscopy and X-ray diffraction (XRD) were used to characterize the nanocomposite structure. In or...
[ 5 ] - An Electrochemical Investigation of Nano Cerium Oxide/Graphene as an Electrode Material for Supercapacitors
In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...
[ 6 ] - Power Consumption Minimization of Khormoj Compressor Station
Arguably, the natural gas transmission pipeline infrastructure in Iran represents one of the largest and most complex mechanical systems in the world. The optimization of large gas trunk lines known as IGAT results in reduced fuel consumption or higher capability and improves pipeline operation. In the current study, a single-objective optimization was conducted for Khormoj compressor station o...
[ 7 ] - ارزیابی اثر حضور نانو رسها بر روی خواص فیزیکی و مکانیکی پوششهای نانوکامپوزیت پلیمری
پلیمر های نانوکامپوزیتی دسته جدیدی از مواد هستند که با اضافه کردن مقدار بسیار کمی نانوذره معدنی در پلیمر خواص بسیار خوبی درآن ایجاد می کنند . شناسایی و به دست آوردن مقدار بهینه این مواد پرکننده بمنظور رسیدن به بهترین خاصیت، امر بسیار مهمی است .این مواد پرکننده باید از لحاظ اقتصادی مقرون به صرفه باشند و به راحتی با پلیمر ترکیب شوند، همچنین مواد پرکننده نباید کاهش چشمگیری در دیگر خواص خوب ماده ای...
