Description

Technical Field

[0002] At present, most butyl rubber plasticizers only use rotary cutters for rotary cutting and stirring for plasticization. This method has unstable temperature control and plasticization effect, resulting in large fluctuations in product quality. In addition, the size of butyl rubber particles during the plasticization process cannot be observed in a timely manner. The plasticizer needs to be adjusted when the butyl rubber particles are discharged to plasticize butyl rubber particles with a qualified particle size. In addition, when using the current plasticizer to plasticize butyl rubber, a single cutting and plasticization method cannot produce butyl rubber particles quickly and efficiently, and the particle size of the produced butyl rubber cannot be adjusted.
