六棱同步转子密炼机的应用研究

Application Research of Internal Mixer with Six-wing Synchronous Rotor

以全钢子午线轮胎胎面胶生产为例,研究F370型六棱同步转子密炼机的应用效果,并与F370型四棱异步转子密炼机进行对比。结果表明:六棱同步转子的相位角以150°为宜;与四棱异步转子密炼机相比,六棱同步转子密炼机的生产效率明显提高,胶料的成团性能较好,炭黑分散度提高;硫化胶的拉伸强度有所提高,撕裂强度和耐磨性能明显提高,压缩生热降低,其他性能相近。

Taking the tread compound of TBR tire as an example,the application of model F370 internal mixer which had six-wing synchronous rotor was studied and compared with another model 370 but with four-wing asynchronous rotor.The results showed that the optimum phase angle of six-wing synchronous rotor was 150°.Compared with the internal mixer with four-wing asynchronous rotor,the production efficiency of the internal mixer with six-wing synchronous rotor was significantly higher,mixing performance was better,dispersion of carbon black was improved,tensile strength of the vulcanized rubber was slightly improved,tear strength and wear resistance were significantly improved,compression heat build-up decreased,and other properties were similar.
