Rheological characteristics of powder injection molding PIM feedstocks play an important role in final properties of manufactured MMCs. In this study, six formulations composed of magnesium and SiC powder (99:1 wt.%) and a specific binder  were prepared to investigate the influence of binder composition, powder to binder ratio, time and temperature on rheological properties of the feedstock. Th...

INTRODUCTION Melorheostosis(synonyms: candle bone disease, melting wax syndrome, Leri disease) is a rare chronic bone disorder, first described in 1922 by Leri and Joanny. Men and women are equally affected, and no hereditary features have been discovered. Onset is insidious, and most common symptom is pain. Most common part of bone is diaphysis of the long bone of lower limb rarely the axial s...

the potential indoor air impacts of burning candles have drawn increased attention in recent years.  burning paraffin waxes itself, regardless to wick and the essence, produce some allergens and even carcinogenic compounds. further biorefining of petroleum paraffin wax with proper bacteria is one of the proposed resolutions to decrease the health threat. therefore in this study iranian heavy cr...

Lacquer wax is an important fatty resource obtained from the mesocarp of the berries of Toxicodendron vernicifluum. In order to expand the applications of lacquer wax, we hydrolyzed it after establishing the best conditions for the acid-catalyzed hydrolysis using a Box-Behnken design. Then we synthesized a quarternary ammonium gemini surfactant by a three-step reaction. The surface properties o...

The purpose of the study was to evaluate the suitability of laboratory scale spheronizer for the production of spherical pellets loaded with diltiazem hydrochloride by wax combination. The 1:1 combination of cetyl alcohol and hydrogenated castor oil, as low and high melting point waxes, were used. The various production variables affecting the different characteristics of pellets and the proces...

Deposition of wax on a cold surface is a serious problem in oil production. Progress in developing more effective wax inhibitors has been impeded by the lack of an established mechanism connecting the molecular structure to inhibitor efficiency. Some comb-like polymers having long alkyl side chains are known to decrease the rate of wax formation. Among several possible mechanisms, we investigat...

A significant amount of heat is wasted in manufacturing process, electricity generation, chemical and industrial process. Recovery and reuse of this energy through storage can be useful in conservation of energy. In the present study, a double pipe type heat exchanger has been designed and fabricated for low temperature industrial waste heat recovery using phase change material (PCM) paraffin w...

The rheological behavior of feedstocks used in powder injection molding technology influences strongly on the final properties of the products. Powder loading is one of the important factors that have a great distribution on rheological behaviors. By using the gas atomized spherical 316L stainless steel powder and the binder of 55% paraffin wax+ 40% polyethylen+ 5% stearic acid, four kinds of f...

Wax printing is one of the most widely used techniques to print hydrophobic barriers on hydrophilic microfluidic paper-based analytical devices (µPADs) based its simplicity, speed, and low cost, allowing large-scale production. Nonetheless, function just passive, without any action fluids. Thus, this work proposes multifunctional composites conductive graphene nanoplatelets (GNPs) integrated in...

Abstract In recent years, the use of polyethylene (PE) for asphalt modification has been gaining increased attention due to environmental sustainability and cost-saving benefits. To optimize performance PE-asphalt blends, it is necessary understand polymer-binder interactions their impact on properties modified binder. this study, low-density (LDPE) with low high melt flow index (MFI), i.e., LD...
