剪切啮合型转子的混炼性能研究

介绍剪切啮合型转子的特点，并与四棱同步转子和普通啮合型转子进行不同填充因数、压砣压力、冷却水温度和转子转速下的对比试验。结果表明，混炼过程中密炼机存在最佳填充因数；相同的转子转速（低于150 r·min^-1)和压砣压力下，剪切啮合型转子混炼性能较好；相同冷却水温度下，剪切啮合型转子炭黑分散性较好。;The mixing behavior of shearing-meshing rotor in internal mixer was introduced，and compared to that of 4-wing synchronous rotor and conventional meshing rotor at different filling factor，rotor speed，ram force and cooling water temperature.The results showed that，the mixer had an optimal filling factor；the shearing-meshing rotor had better mixing efficiency at same rotor speed(≤150 r·min^-1) and ram force，and gave the compound better dispersibility of carbon black at same cooling water temperature
