Keeb kwm luv luv ntawm Polypropylene Development

Nyob rau hauv 1954, G. Nata thawj polymerized propylene rau hauv polypropylene (siv aluminium titanium chloride ua ib qho catalyst) thiab tsim cov kev xav ntawm kev qhia polymerization, uas nyiam cov neeg mloog.
Nyob rau hauv 1957, Italian tuam txhab Montecatini thiab American tuam txhab Hecules tsim polypropylene ntau lawm nroj tsuag ntawm 6000t / a thiab 9000t / a, feem.
Los ntawm lig 1960s mus rau nruab nrab -1970s, polypropylene tau nkag mus rau lub sijhawm ntawm kev loj hlob zoo.
Txij li thaum xyoo 1980s, polypropylene ntau lawm tau nyob rau hauv pem hauv ntej ntawm hluavtaws resins, thiab tam sim no tsuas yog qis dua polyethylene, qeb thib ob.
Tuam Tshoj pib tshawb fawb cov txheej txheem ntawm polypropylene hauv xyoo 1962. Txij li xyoo 1980s, polypropylene tau tsim sai heev hauv Suav teb. Tuam Tshoj tau tshaj tawm qee qhov kev tsim khoom siv thev naus laus zis thiab khoom siv polypropylene, thiab tau tsim ntau qhov chaw loj thiab nruab nrab polypropylene ntau lawm xws li Yanshan, Yangzi, thiab Liaoyang. Ntau cov chaw tsim khoom me me ntawm polypropylene kuj tau tsim nyob rau hauv ntau thaj tsam, uas tau ua lub luag haujlwm hauv kev txo cov khoom siv-xav tsis sib haum. Qhov loj zuj zus ntawm cov nplai ntau lawm tau ua rau Tuam Tshoj cov polypropylene cob ntau lawm nkag mus rau theem kev loj hlob sai
