Evaluation and Modification of Rubber Mixing Process

Abstract

- The paper Studied the relationship between hardness of rubber ,its properties and compounding ingredients.Further it progressed towards enhancing the abrasion properties of same.Increasing the aesthetic appearance and minimising the losses during processing and post processing is also included the work .Rubber includes both natural and synthetic polymers.Compounding ingredients being the chemicals added to achieve the desired traits. Five steps are used to achieve the result of research.The first step,incorporates the observation and analysis of processed/manufactured products to understand defects and issue. The second step, inovoles findings from the observation done in first method.The third step is dedicated to solving the outcomes of previous step.The fourth step, is precise calculation of chemicals and materials to obtain the absolute proportion of all.The final step being the most vital one ,deals with instruments and techniques to test the product composition developed .The desired result reflected the success of research . Additives altered the harness and chemical properties of rubber ,thus impacting the overall process time and characteristics of compound .Bound rubber dropped and molar masses of polymers were also reduced .The cross link density was relatively stable and stronger, achieved during vulcanising with the help of accelerator and sulphur .The strength was improved using carbo black at the beginning.There is a relationship between additives and their effect on hardness of compound.the speed of reaction is altered and losses are minimised which occurred due to external chemical and mechanical forces
