The Design And Research Of New Experimental Mixer

With rapid development of rubber and plastic industry as well as other polymer material industry,the internal mixer is playing a greater and greater role in polymer material production,and there is a higher requirement for the performance of the internal mixer. Especially in recent years,the development and utilization of many new products such as radical wire tire,acrylonitrile butyl rubber tube,raw edge V-belt and rubber oil seal as well as the development of rubber and plastic mixtures deserve perfect function of the internal mixer. This is because the performance of the internal mixer is related to the quality of mixed stock,and also to the performance and longevity of production. The developing of a new kind of clearance internal mixer can deal with the problem.The main work and achievement of this paper are as follows:1.On the basis of collecting a vast amount of domestic and overseas data,the author design and made a clearance internal mixer. Especially,the author also conducted a thoroughgoing and painstaking ideological work about the mixing mechanism of clearance internal mixer.2. Here,the author studied the theory and made experiments to the mixing process have the clearance internal mixer and formed physical model and the relative mathematical model.3.Using the same recipe and technological facts,the author compared the difference between tow kinds of rubber products in clearance internal mixer on the operation.4.Taking use of experiments carried out,the parameters such as maximum power,unit energy consumption,the time of the processing of mixing,the capacity of production,exited rubber temperature,was studied. The optimum condition can be obtained from the discussing the effect of the recipe factors (rubber,filler,softener and their mixture ratio) and technological factors. The author constructed the math model of the clearance internal mixer. Further,on the basis of the conclusions of the mathematical models of the clearance internal mixer were attempted to be building in terms of statistical theory. Through the models it was found that the inherent laws in the process of mixing of the clearance internal mixer.
