Proses pirolisis dilakukan dengan memanfaatkan LDPE,PP dan PET menambahkan katalis zeolit sebagai bahan dasar pembuatan bakar cair. Metode penelitian digunakan adalah Thermal Catalytic Cracking didefinisikan proses perengkahan rantai hidrokarbon panjang bantuan pana...

یکی از پارامترهای مهم محیط­های پخش نوترون، طول نوترون حرارتی است. روش مرسوم محاسباتی استفاده کد MCNP برمبنای توزیع شار در محیط و برازش تابع ریاضی مربوطه بر آن این پژوهش، روشی نوین که مبنای کارت PTRAC است، ارایه شده پارامتر برای آب­سبک اساس روش­های فوق محاسبه با مقادیر گزارش مراجع مقایسه گردیده تطابق خوبی نیز مشاهده حسن فوق، عدم نیاز به علاوه فرض می­شود تا محل چشمه، فاصله­ی کافی وجود دارد. مسأله...

A structural model for the calculation of equivalent permittivity nanocomposites based on low-density polyethylene (LDPE) and epoxy resins (ERs) with inorganic fillers was developed. It assumed that each nanoparticle centered in an interfacial region composed three layers case LDPE-based nanocomposites, two ER-based nanocomposites. The estimation designed flat samples height $g$ , divided into ...

Polyethylenes (PE) are the most commonly occurring ingredients for post-consumer recyclates (PCR). The structure–property relationships of different types model PE-based blends established using multiple thermo-rheological analyses. Although considered “simple”, complex behavior is experimentally demonstrated first time metallocene-catalyzed, linear, low-density polyethylenes (mLLDPE) with micr...

Indian gooseberry (Emblica officinalis Gaertn.) is an indigenous important hardy underutilized fruit crop of India. The objective the present investigation was to evaluate effect Modified Atmospheric Packaging- Low Density Polyethylene (MAP-LDPE) on storage life and quality (physico-chemical attributes) different cultivars Aonla fruits up 12 days. Physico-chemical attributes such as Physiologic...

Abstract UF-SiAPP was prepared by modifying ammonium polyphosphate with the urea formaldehyde resin (UF), tetraethylorthosilicate (TEOS), and vinyltriethoxysilane (A-151). Moreover, a new intumescent flame retardant (IFR) used for low density polyethylene (LDPE) obtained mixing tris(2-hydroxyethyl) isocynurate (THEIC). The structure, morphology, mechanical properties of retardants LDPE composit...

The use of recycled raw materials and renewable sources are necessary for economical, social, environmental technological development. In this context, work aims to study the influence two lignin types, one derived from pine (Lig I) other eucalyptus, II) on polymer composites properties low density polyethylene (r-LDPE-Al) Pinus Elliotti wood flour (WF), in proportion 70% 30% matrix/reinforceme...

nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. antimicrobial nanocomposite ldpe films containing zno nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-zno pulse 10% polyethylene grafted maleic anhydride (pe-g-ma), w/w pure ldpe), were p...
