摘要:密炼机瞬时功率控制的实质是控制混炼物料的粘度。采用瞬时功率控制可减小混炼胶的门尼粘度波动。全自动控制混炼过程中,混炼过程参数,如转子转速、填充因数、压砣压力和胶料温度对混炼胶质量有影响;采用瞬时功率控制可以减小一些因素的影响,但并非对所有因素的影响都有效。MLJ300密炼机智能控制系统可以实施瞬时功率控制,最佳效果是将胶料门尼粘度波动范围控制在-3~+3。

Abstract:The essence of the instantaneous power control in internal mixer is to control the viscosity of mixing material.The Mooney viscosity fluctuation of mix can be decreased by using instantaneous power control.During the autocontrol mixing,the parameters of the mixing process,such as rotor speed,filling factor,ram pressure and mix temperature have effect on the mix quality;and the effect of some parameters can be decreased by using instantaneous power control.The instananeous power control can be realized using MLJ300 intellegent internal mixer control system,by which the Mooney viscosity fluctuation of mix can be controlled within ±3.
