据Plasten工程公司称，当加入回用胶料或母炼胶时，通过把密炼机装于机械料斗处，则能获得较好的产品一致性和较短的生产周期，该公司目前正出售TSM公司的混合机头。 若混炼效果较差可通过增加塑化时间或增加反压力得以补偿，但这两种办法导致产品产生较大的热和机械降解、脆性 According to Plasten Engineering, better product consistency and shorter cycle time are achieved by adding the mixer to the mechanical hopper when adding the reclaimed rubber or masterbatch, which the company is currently selling TSM mixer head. If the mixing effect is poor, it can be compensated by increasing the plasticizing time or increasing the backpressure, but both methods lead to greater thermal and mechanical degradation of the product, brittleness
