聚丙烯催化剂浆料中镁含量测定方法研究

Study on determination of magnesium content in polypropylene catalyst slurry

生产高效聚丙烯产品的装置是液相本体法聚丙烯装置,设计是采用高效催化剂(Ti Cl4/Mg Cl2·ED)为主催化剂,催化剂量过高,可能引起爆聚,形成塑化结块,严重时使聚合釜超压,发生爆炸。通过测定催化剂浆料中镁含量可控制催化剂加入的量,本文进行初步探讨。

efficient production of polypropylene products unit is liquid ontology method polypropylene unit,the design is to use an efficient catalyst(TiCl4/MgCl2·ED)as the main catalyst,catalyst dosage is too high,can lead to implosion,plasticizing agglomerate formation,serious when make the polymerizer overpressure,explosion.By measuring the content of magnesium in catalyst slurry,the amount of catalyst can be controlled.
