摘　　要：为优化聚四氟乙烯(PTFE)悬浮树脂生产工艺,采用微型粉碎器对平均粒径约1.5mm的PTFE悬浮树脂进行粉碎,探讨填充量、粉碎时间、树脂初始含水量以及机械刀片尺寸对粉碎后树脂粒径的影响。结果表明,粉碎填充量为其容积的1/4时,所得到的粉碎结果具有更好经济价值;粉碎5 min比6 min更具经济性;相较于干燥的PTFE悬浮树脂,有一定含水量的树脂更利于粉碎;第2层刀片角度30°、长度100 mm时,粉碎得到的树脂平均粒径最小。The paper discusses the influence of the amount of filling,the time of crushing,the initial moisture content of the resin and the size of the mechanical blade on the result of crushing by tracing the crushing law of the PTFE suspension resin in the micropulverizer,so as to provide a reference for the industrial optimization of the crushing process parameters of the PTFE suspension resin.
