Polypropylene / polystyrene blends containing montmorillonite (MMT) were prepared using a twin screw extruder followed by fiber spinning. The melt intercalation of PP and PS alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (MPP). The crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (PP/PS) nan...

Flotation is a complex process that exhibits high dimensionality which makes modeling and optimization very challenging. One technique to alleviate the problem combine variables together into more informative ones. Bubble surface area flux air recovery are examples of reduction. Gas holdup also captures effect plurality including gas rate, bubble size, surfactant type, concentration. This work ...

OBJECTIVE DOE Chicago Operations %ice The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. Blends of normal (25 % amylose) and high amylose (50 and 70% amylose) corn starch (containing between 60 and 70 % of the mixture by weight) and synthetic polymer were used in this research. Two diff...

Double blends were prepared by mixing copra oil (CO) with seed oils of Brassica juncea (BO), Madhuca nerifolia (MO) and Sessamum indicum (SO) in different volume proportions. The consumer-acceptable oil blends were selected based on the opinion of a panel of consumers about the palatability and other physical properties of French fries prepared using the oil blends. The effect of the selected o...

In this paper, the implications of melt compatibility on thermal and solid-state properties of linear low density polyethylene/high density polyethylene (LLDPE/HDPE) blends were assessed with respect to the effect of composition distribution (CD) and branch content (BC). The effect of CD was studied by melt blending a metallocene (m-LLDPE) and a Ziegler-Natta (ZN) LLDPE with the same HDPE at 19...

In this review, progress towards a fundamental understanding of the rheologymorphology relationship in immiscible polymer blends is discussed. The behaviour of biphasic polymer fluids, containing Newtonian components and subjected to simple shear flows is relatively well understood at present. The behaviour of these “simple” blends will be discussed first, as it serves as a reference for the ot...

background:the present study designed to test  effects of defatted soy-fortified wheat bread on the organoleptic properties as well as influences on rat growth rate. methods: defatted soy flour (dsf) was blended with wheat flour with extraction rate of 82-84% at 3, 7, and 7% levels plus 3% sugar. bread produced with these blends compared with regular taftoon bread and was tested for chemical an...

Kinetic models are the most important tools for the prediction and evaluation of the flotation circuits performance. In order to determine the kinetic order and rate of flotation of a Gilsonite sample, flotation experiments were conducted using the combination of Gasoline-Pine Oil, and one test without any collector and frother. The pulp density was 10% and the experiments were carried out in b...
