Simulated temperature measuring method for rubber tires

Abstract

The invention belongs to the technical field of chemical engineering of rubber tires, particularly relates to a simulated temperature measuring method for the rubber tires. According to the simulated temperature measuring method, the rubber tires are subjected to first temperature measurement and secondary temperature measurement, and accordingly, result accuracy is guaranteed through two-time temperature measurement. A thermocouple is utilized to perform vulcanization temperature measurement on the tires, so that vulcanization degree of the tires and vulcanization matching conditions of rubber can be known clearly, and the basis is provided for further formula optimization and process improvement. Overall temperature measurement of the tires is replaced by partial temperature measurement, frequency of temperature measurement can be greatly increased under current circumstances, and errors caused by accidental factors during actual temperature measurement are reduced. Through the vulcanization temperature measurement, vulcanization time of tires in some specifications can be effectively shortened, so that tire quality and working efficiency are improved, more new ideas which cannot be realized during the actual temperature measurement can be realized, and resources and manpower are saved greatly.

Description

technical field [0001] The invention belongs to the technical field of tire chemical industry, and in particular relates to a simulated temperature measurement method for rubber tires. Background technique [0002] Rubber is a poor conductor of heat. Thick rubber products like tires will form a temperature field inside during the vulcanization process, forming a temperature gradient with the vulcanization mold. Since the tire is a thick product with non-equal thickness, and rubber is a poor conductor of heat, due to the different distances between each part and the heat source, during the vulcanization heating / cooling process, the heating history of each part of the rubber material is quite different, that is, vulcanization The process is actually a non-isothermal process with uneven distribution of temperature field. The inhomogeneity of this vulcanization process leads to some parts of the finished tire being over-sulfured and some parts under-sulfured. Over-sulfurization...

Problems solved by technology

Now the main working method of temperature measurement is carried out during the actual tire vulcanization process, which can make the measurement closer to the actual production situation, but on the other hand, it also brings fewer temperature measurements, which affects the accuracy of the data and the actual temperature measurement. Work consumes a lot of material and financial resources and other practical problems
