一直以来,笔者所在公司都采用密炼机恒速工艺对终炼胶进行混炼,但在生产过程中,如果混炼转速过高,胶料生热过快,导致快速排胶,容易造成终炼胶料夹生、粉料分散不均和产生熟胶粒等质量问题。为了控制胶料质量,一般会采用低速混炼。但是转速过低,混炼效率就会受到影响,并且对于无极变速的直流电机,其输出功率与混炼转速成正 All along, the author’s company uses a constant speed mixer process for the final mixing of rubber, but in the production process, if the mixing speed is too high, the plastic heat too fast, resulting in rapid plastic, likely to cause the final Rubber mixing raw folder, powder uneven dispersion and the production of plastic particles and other quality problems. In order to control the quality of the rubber, it is generally used at low speed. But the speed is too low, the mixing efficiency will be affected, and for the speed of the DC motor, the output power and mixing speed is positive
