Experimental Validation of the Horikx Theory to be Used in the Rubber Devulcanization Analysis
(Springer/Plenum Publishers, 2019-07)
The waste rubber and end-of-life tires management has become a serious environmental problem. It is well known that the best way to carry out the disposal of these wastes is through recycling by devulcanization. Therefore, ...
Recycling of rubber waste through thermomechanical devulcanization
(2019)
Approximately 70% of the rubber produced in the world is used in tires. The number of waste tires discarded worldwide each year is close to 330 million (approximately 4.4 million tons) and considering the average percent ...
Devulcanization of natural rubber industry waste in supercritical carbon dioxide combined with diphenyl disulfide
(Pergamon-Elsevier Science Ltd, 2020-12)
The elimination of rubber wastes without affecting the environment is one of the most important challenges of the 21st century waste management. Accordingly, the present work is focused on the recycling of natural rubber ...
Thermo-mechanical devulcanization and recycling of rubber industry waste
(Elsevier Science, 2019-05)
This work is focused on the recycling of natural rubber industry waste by means of thermo-mechanical devulcanization. With that aim, tests were carried out in an industrial twin-screw extruder, at different barrel temperatures, ...
Recycling of waste tire rubber: microwave devulcanization and incorporation in a thermoset resin
(Elsevier, 2016-11)
This study focused on the possibility of recycling Waste Tire Rubber (WTR) to be used as polymer modifier. Thus, WTR was grinded into powder, at ambient temperature, with a disc mill PQ500 and microwave electromagnetic ...
Revulcanization Kinetics of Waste Tire Rubber Devulcanized by Microwaves: Challenges in Getting Recycled Tire Rubber for Technical Application
(2019-09-16)
Recycling is a process toward sustainable development. However, it does not do any good to recycle a material trying to contribute to the environment, if the final properties of the recycled material do not point to a ...
Chemical Modifications in Styrene-Butadiene Rubber after Microwave Devulcanization
(AMER CHEMICAL SOCWASHINGTON, 2012)
Microwave devulcanization has been studied as a method for elastomer recycling, which is based on the conversion of the reticulated and infusible structure of thermosetting rubbers in free polymeric chains able to be ...
Desenvolvimento de novos compostos de borracha natural a partir da desvulcanização em extrusora com rosca dupla
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2017-03-08)
The present study investigated the utilization efficiency of an intermeshing
co-rotating twin-screw extruder (ICTSE) in the devulcanization of natural rubber
compounds (NR), evaluating the physical, chemical and mechanical ...
Regeneração de rejeito espuma de SBR através de extrusão no estado sólido e incorporação em SBR virgem
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2017-09-29)
The objective of the present work is the study of the recycling of vulcanized rubber foam waste from the footwear industry through the solid state extrusion process known as Solid State Shear Extrusion (SSSE). The industrial ...
