In this study a type of polymeric composites from melting poly Unsaturated polyester as a basic substance with powdered sawdust was prepared, studying some of it is mechanical properties, which was included: Impact Strength (I.), Yong modulus (E), hardness (B.) and compression Strength (C.). Polymeric composites before and after reinforcing were studied by comparison between them. It was noticed increasing resistance of Yong modulus (E), Impact Strength (I.), hardness (B.) and compression Strength (C.). Also, It is studied the effect of some acids like (, H2SO4, HNO3) with concentrations (0.5 N; 1N and 1.5N) respectively. Some physical properties were studied as absorbance and poly 's diffusion coefficient before and after reinforcing. The results showed increases in values of these properties with increasing concentration of acid and time of polymer's immersion in the acidic solution.
In this study, the octane number of gasoline was improved by using isobutanol isobutanol prepared in the treatment of tire inner rubber with kerosene at different temperatures and in different quantities, and then treated with concentrated capranic acid and water. Then, the formed alcohol and water are separated from the acid kerosene using fractional distillation, where the water and alcohol are separated, leaving the acid and kerosene, and then the distilled liquid (isertoy mixture) is heated on a column containing sodium tetramer. And mixed by 1, 1.5, 3, and 5% with gasoline, where the octane number was raised. Cassiochromatographic octane number assays were performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
