تأثير إضافة مادة الغبار المتطاير لمرسبة الفرن في معامل الاسمنت"fly ash" في الخواص الريولوجية والميكانيكيه لمطاط النتريل"NBR"

Abstract

In this researcht was study the effect of fly ash on the general properties of NBR rubber. Fly has a small particle size which mean large surface area, thus addition of fly ash to the NBR rubber shows improvement in the mechanical properties The result show decreasing the cure time and increasing in scorch time as addition of fly ash increase, hardness and specific grafity increasing as addition of fly ash increase, also results show that increasing in tensile strength and modulus and decreasing in elongation as addition of fly ash increase
