The significant increase of Waste Electric and Electronic Equipment (WEEE) has led to an important research in upgrading recycled engineering plastics by means of a blending technique. Classical twin-screw extrusion is compared to a new blending technique, where two polymers are combined together and then flow in several static mixers. This technique allows to obtain different morphologies of c...
در این پژوهش آلیاژهایی از دو نوع ABS و سه نوع کامپاند PVC به روش اختلاط مذاب تهیه و تأثیر نوع و ترکیب درصد اجزاء بر خواص فیزیکی و مکانیکی و اشتعال پذیری آنها مورد مطالعه قرار گرفت. مطالعات نشان داد که هر دو نوع ABS استفاده شده در این تحقیق، تأثیر مشابهی بر روند تغییرات خواص آلیاژها داشته ولی بهبود خواص فیزیکی و مکانیکی و همچنین کاهش اشتعال پذیری ABS به شدت تابع ترکیب درصد اجزاء و نوع PVC است. د...
سالانه هزاران نفر در آتش سوزی جان خود را از دست می دهند. در صورتی که از مواد ضد شعله وری مناسب در مواد و محصولات پلاستیک استفاده شود، این رقم می تواند به میزانی زیاد کاهش یابد. در دو دهه اخیر به دلیل وضع قوانین جدید دولتی در رابطه با ایمنی مصرف کنندگان،دیر سوزکننده ها رشد شگرفی داشته اند. میزان اشتعال پذیری یک پلیمر اصلی با نحوه تجزیه آن در دمای پایین و تولید محصولات گازی و چگونگی سوختن این محص...
A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

Classes of Abaffy-Broyden-Spedicato (ABS) methods have been introduced for solving linear systems of equations. The algorithms are powerful methods for developing matrix factorizations and many fundamental numerical linear algebra processes. Here, we show how to apply the ABS algorithms to devise algorithms to compute the WZ and ZW factorizations of a nonsingular matrix as well as...
a new method was used to prepare abs/pa6 blends by in situ polymerization and compatibilization method. in this process, ε-caprolactam monomer was polymerized in presence of abs via activated anionic polymerization to produce pa6. the main ingredients of the reaction mixture included: monomer ()ε-caprolactam), catalyst na-caprolactamate), microactivator hdi)( and macro-activator sma)(. then, in...
background: hydatid cysts are encountered frequently in regions endemic with livestock. the basic treatment for a hydatid cyst is total surgical removal of the cyst and its inner contents. hypertonic nacl or diluted betadine solution are used as germicidal agents for most hydatid surgeries. however, the germicidal efficacy of the ankaferd blood stopper® (abs) has not been investigated. thus, we...
