Tsis ntev los no, cov tshuaj catalyst metallocene polypropylene uas tau tsim los ntawm Beijing Research Institute of Chemical Industry tau ua tiav thawj qhov kev sim siv hauv kev lag luam hauv chav ua haujlwm polypropylene ntawm Zhongyuan Petrochemical, thiab tsim cov homopolymerized thiab random copolymerized metallocene polypropylene resins nrog kev ua tau zoo heev. Tuam Tshoj Sinopec tau los ua thawj lub tuam txhab hauv Suav teb kom ua tiav kev tsim cov thev naus laus zis metallocene polypropylene.
Metallocene polypropylene muaj qhov zoo ntawm cov ntsiab lus tsawg soluble, siab pob tshab thiab siab gloss, thiab yog ib qho tseem ceeb rau kev hloov pauv thiab kev txhim kho ntawm kev lag luam polypropylene thiab kev txhim kho siab. Beihua Institute tau pib tshawb fawb thiab kev txhim kho ntawm metallocene polypropylene catalyst hauv xyoo 2012. Tom qab kev sim me me, qauv xeem thiab kev sim tsav dav hlau scale-up npaj, nws daws cov teeb meem kev siv tshuab xws li kev tsim qauv catalyst, kev npaj txheej txheem thiab catalytic kev ua haujlwm optimization, thiab ua tiav tsim metallocene polypropylene catalyst. Propylene catalyst technology thiab kev tsim cov khoom catalyst. Hauv kev ntsuam xyuas sib piv hauv qab tib yam polymerization mob, catalyst muaj kev ua haujlwm siab dua li cov catalyst xa tuaj, thiab cov khoom polypropylene npaj tau muaj cov duab zoo dua thiab tsis muaj agglomeration.
Txij li thaum Lub Kaum Ib Hlis xyoo no, cov catalyst tau ua tiav cov kev sim hauv kev lag luam hauv Hypol process polypropylene cog ntawm Yangzi Petrochemical thiab lub nplhaib yeeb nkab txheej txheem polypropylene cog ntawm Zhongyuan Petrochemical, thiab tau txais cov txiaj ntsig zoo. Qhov kev sim hauv kev lag luam no hauv Zhongyuan Petrochemical yog thawj zaug hauv Suav teb los tsim cov copolymerized metallocene polypropylene ntawm lub nplhaib yeeb nkab polypropylene ntaus ntawv, uas tau tso lub hauv paus ruaj khov rau kev txhim kho siab ntawm Sinopec kev lag luam polypropylene.
