Devulcanization of waste tire rubber by microwaves
Reclaiming is considered to be the most attractive method of reusing waste tire rubbers . Devulcanization of waste rubbers, as a reclaiming method, is a technique in which energy is provided to the material in order to destroy, totally or partially, the three-dimensional network formed during vulcanization . It aims to restore the flow capacity of the vulcanized rubber by breaking down its cross-linkings.

Devulcanization of Waste Tire Rubber by Powerful
Ground rubber tire (GRT) is devulcanized in a continuous process where the rubber crumb is conveyed by a screw extruder to a thin gap between a stationary die and a vibrating horn. Ultrasound amplitude, gap thickness and the duration of the treatment are varied, and their effect on the rubber properties is studied.

Evaluation of Waste Tire Devulcanization Technologies
waste tires. Devulcanization is a potential method of recycling waste tire rubber. As its name implies, in the process of devulcanization, the structure of the vulcanized waste rubber is modified. The resulting material can be revulcanized or transformed into useful products (see complete definition on page 4).
