Dab tsi yog cov txheej txheem ntau lawm ntawm polypropylene?

1 txoj kev slurry. Polymerization nyob rau hauv tsis sib xws xws li hexane yog thawj qhov kev lag luam thiab kev siv ntau tshaj plaws rau hnub tim. 2 ua kua theem ib txoj kev. Polymerization tau nqa tawm hauv cov kua dej ua kua dej ntawm 70 ° C thiab 3 MPa. 3 roj theem hom. Lub polymerization yog nqa tawm nyob rau hauv tej yam kev mob uas propylene yog nyob rau hauv lub xeev gaseous. Qhov tom kawg ob txoj hauv kev tsis siv thinner, txoj kev ua kom luv, thiab lub zog siv tsawg. Cov theem ua kua theem tau tam sim no tau qhia qhov zoo dua yav tom ntej.
