Abstract
In actual production,polypropylene plant extrusion pelletizer is easy to appear the phenomenon of cutter damage,resulting in the emergence of unqualified pellets,which can cause customer quality complaints and cause certain economic losses.Prolonging the service life of the cutter can not only guarantee the appearance quality of the granulation,but also save the cost of cutting material,and maintain the long cycle production of the extruder,so as to achieve the goal of reducing cost and increasing efficiency.The influencing factors of the service life of the cutter are studied,including the granulation process,the PP brand and the polymerization process,etc.In order to prolong the service life of the cutter,the following improvements can be taken:when the granulation process is adjusted,the change of the cutter current should be concerned.The temperature of the pellet water,the temperature of the template and the temperature of the cylinder are adjusted to make the material have a proper grain hardness.By optimizing the polymerization process,the production quantity of the transition material is reduced when the brand is cut,and the material stability is maintained at the same grade.关键词
