Effect of Microwave Drying on Cure Characteristics of Natural Rubber

Abstract:

In this work, the cure characteristics of nature rubber (NR) dried by microwave and hot-air were analyzed by using Vulcameter. The effect of curing temperature on induction period (tC10), optimum cure point (tC90), maximum Torque (MH) and minimum induced torque (ML) were studied. The results showed that the tC10, tC90 and ML of NR dried by hot-air were bigger than those of NR dried by microwave, however, the MH of former was bigger. And the tC10, tC90 of NR dried by microwave or hot-air can fitted Arrhenius equation well, the K1, K2 and K of Arrhenius equation coefficient for NR dried by microwave were all bigger than those of NR dried by hot-air. With the increasing of curing temperature, the MH of NR dried by microwave or hot-air decreased gradually and its trend was well satisfied with linear relationship, and the MHo of NR dried by microwave was bigger than hot-air drying.
