Rubber in Engineering Applications (Experimental Work). Research Series

      Аннотация: This book include experimental work; the effect of contaminate (fungi) during bad conditions of transportation and Storage, genus Aspergillus Niger was isolated from contaminated samples for both types (SMR20, SVR20) and study the physical and mechanical properties, which included tensile strength, hardness, abrasion and extraction in addition to the study influenced main constituent of natural rubber growth of fungus using the technique of infrared spectrum. The results showed a negative influence on the physical and mechanical properties for the growth of fungus, in addition to disappearance of some bands of natural rubber such as (C-H) and (C-N) bands. Also in Diaphragm Actuator, two new recipes were proposed to work instead of commercial recipe with experimental and analytical study to prove the high performance properties and work-ability. The finite element method by ANSYS 13 software was used to study the behavior of these compounds with Mooney-Rivlin 2-parameters during the work pressure range. Most of the results are acceptable competitive. The 20% blending ratio is the optimum blending ratio for scrap tires rubber oil depending on experimental test results in final part.
