摘要
研究XLH-150型双转子连续混炼机的混炼工艺参数与胶料性能间的关系,确定XLH-150型连续混炼工业化机台的最佳混炼工艺,并与传统密炼机三段混炼工艺进行对比。结果表明:XLH-150型连续混炼工业化机台的最佳混炼工艺为初炼采用GK-45E型啮合型密炼机,转子转速为50 r·min^(-1),温度为40℃,混炼时间为270 s,填充因数为0.6;补充混炼采用XLH-150型双转子连续混炼机,转子转速为40 r·min^(-1),过2遍连续混炼机,各段温度分别为70,65,60和55℃。采用连续混炼工艺的胶料性能优于采用传统三段混炼工艺的胶料性能,即胶料的Payne效应降低11%,滚动阻力降低15%,拉伸强度和撕裂强度略有提高;同时生产效率提高44%以上,总单位能耗降低39%。
The relationship between the compound properties and mixing process parameters of the XLH-150 double rotor continuous mixer was studied,and the optimum process parameters of the industrial system based on XLH-150 continuous mixer were determined and compared with the three-stage mixing process of traditional internal mixer. The results showed that the optimum process were as follows:GK-45E meshing internal mixer was used for the initial mixing,in which the rotor speed was 50 r·min^(-1),the temperature was 40 ℃,the mixing time was 270 s,and the filling factor was 0. 6;XLH-150 double rotor continuous mixer was used for the subsequent mixing,in which the rotor speed was 40 r·min^(-1),compound passed through the continuous mixer twice,and the temperatures of each section were 70,65,60 and 55 ℃,respectively. The properties of the compound produced by continuous mixing process were better than those with traditional three-stage mixing process,that was,the Payne effect of the compound was reduced by 11%,the rolling resistance was reduced by 15%,the tensile strength and tear strength were slightly improved,while the production efficiency was increased by 44%,and the total unit energy consumption was reduced by 39%.
