Investigating the Heat Transfer and Vulcanization Reactionin Temperature Changes of the Points of a Thick Piece in the Process of Accelerated Sulfur Curing

Abstract

Abstract: Temperature and curing time are among the most important factors influencing the curing of thick parts. In this research, a raw rubber compound was placed in a trapezoidal mold by heating it in a curing press, and the temperature changes of several points inside it was recorded, then the previous experiment was repeated with the cured compound inside it. In justifying the observed temperature changes, it was found that the heat effect created by the reaction in the process is a factor that should be considered in the simulation of the process.
