دراسة تأثير مخلفات الزيوت و الوقود على قيم التقادم المسرع لمانعات التسرب المستخدمة في أنابيب الصرف الصحي في سوريا

الملخص EN

The polymeric materials are visco elastic materials and in opposite to ideal elastic materials as metals, the tension test curve can't be used in designing of these materials, the creep and relaxation curves are used in designing these materials and as we need a very long time (tens years) for having such curves for polymeric materials for determining the durability of these materials that we have to test them in high temperatures and the curves for room temperature have to be extracted.

In this research the accelerated degradation of sewage elastomeric seals used in sewage pipes have been studied in under the influence of three kinds of oils and fuels.

The result shows a big decrease in tension stress and elongation especially to benzene and big increase in hardness and Young's modulus values.
