Research on the Passenger Car Tire Retreading Technology and Processing

摘要

Tire retreading refers to the waste tire repair, polishing and gluing, pressing process, and then curing, which restore its use value. So far it is one of the most direct and most effective and the most economic way of the utilization of waste tire. Normally, because of the high profit, the retreading of truck tire and engineering tire had received much attention, while that of passenger car tire had been ignored. However, as the number of car has been increasing for many years, the passenger tire retreading is urgently needed. In this article, after the further study of related retreading theory, it is determined by using the prevulcanization retreading technology for renovation of radial tire. The renovation process including the carcass of tire inspection, repair, polishing, brush glue, tread molding (including post pad, pre vulcanized tread and pressed), vulcanization, final inspection. And the related equipment has been developed for the passenger tire retreading molding, include lifting inspection machine, model profile grinding machine, winding machine, model setting vulcanizing machine and tread of orientation of short fiber extrusion and other special equipment. This research solved the problem of backward technology, the short service life and poor quality.
