Investigation of using waste banana peels in EPDM as bio-based filler
AKBAY, İsmail Kutlugün
The rubber and plastics sectors have been developing in both 19th and 20th centuries. The most of the developments have been realized in the 20th century. As a result of this, the need for petrochemical products has increased day by day. Synthetic rubber is used to protect vehicle tires, automotive parts, white goods, insulation materials and especially bridges, highways, viaducts and nuclear facilities requiring high elastic modulus from seismic and acoustical effects. Rubber type materials are preferred in many engineering applications due to due to their sufficient properties such as high elasticity. The importance of the study carried out in the rubber industry in order to improve the performance characteristics of the material as well as to increase the production efficiency and reduc...
Investigation of using shelf-life passed milk in EPDM as bio-based filler
AKBAY, İsmail Kutlugün
Waste management of dairy products is an important topic for both economic and environmental aspects. In order to remove or reduce the harmful effects of carbon black used as a filler material, the effects of polymers obtained by using some biological wastes such as shelf-life passed milk instead of carbon black on the physical and mechanical properties of ethylene propylene diene monomer (EPDM) rubber have been investigated. Moving Die Rheometer and Soxhlet extraction tests were applied to the obtained compound and the results were evaluated. MDR test results showed that the scorch time of the samples increased by 10% SP filler, and Soxhlet test results were in line with MDR test. Mechanical analysis showed that the addition of casein polymer improved the elongation at break values of the...
ACCUMULATION OF RECYCLED WASTE TYRE WITHIN DIFFERENT RUBBERS: A KINETIC STUDY
Akbay, İsmail Kutlugün | Özdemir, Tonguç
Waste tyres around the world are increased severely in the last century. The accumulation of waste tyre within poly dimethyl siloxane (silicone) and ethylene–propylene–diene monomer rubber (EPDM) rubbers were examined. The moving die rheometer were used for the kinetic analysis of the samples. The MDR results showed that the silicone sample that has 5% waste tyre content has the better rheological results. Kinetic study examination of both EPDM and silicone rubber were done according to non-linear curve fitting model. The fitting model were conducted as Kamal-Sourour Model. In addition, the fitted model was corrected with fourth order Runge-Kutta model. Moreover, activation energy of both samples were calculated from Arrhenius plot for both rubbers. For EPDM case, it was found 99 kJ/mole a...
