Polypropylene yapamwamba imatanthawuza zinthu zopangidwa ndi polypropylene kuwonjezera pa zipangizo zonse (zojambula, zotsika zosungunuka zosungunuka, kuumba jekeseni wa homopolymer, fiber, etc.), kuphatikizapo koma osawerengeka ku zipangizo zowonekera, CPP, zipangizo zamachubu, zinthu zitatu zapamwamba.

M'zaka zaposachedwapa, mkulu-mapeto polypropylene wakhala nkhondo, mkulu-mapeto PP kupanga mphamvu akupitiriza kuwonjezeka, thovu polypropylene, metallocene polypropylene, atatu mkulu polypropylene, kopitilira muyeso-otsika phulusa polypropylene ndi mitundu ina yatsopano msika ndi otsika, koma kufunika danga ndi yotakata, m'tsogolo msika chitukuko kuthekera kwakukulu;Pofika chaka cha 2021, kutulutsa kwa polypropylene yapamwamba kwambiri kudafika matani 7,963,400, voliyumu yolowera inali matani 2,399,100, ndipo kudalira kunja kudafika 23.57%.Zogulitsa zina zikuyang'anizana ndi momwe zilili ndi mayiko akunja ndipo zikupitilira kuyambira pachiyambi.Nthawi ya 2021-2025 ndi gawo lachitukuko cha polypropylene yapamwamba kwambiri, ndipo kukula kudzachepa mu 2025-2030.

Mu nthawi ya 2022-2030, matani 35.63 miliyoni / chaka cha ma polypropylene akukonzekera kuti ayambe kugulitsa malonda ku China, koma polypropylene yapamwamba imakhala pafupifupi 30% ya kukula kwatsopano kwa polypropylene, kotero ndi pafupi 10.7 miliyoni. matani.Kuwonjezera mbali ya ndondomeko PDH ogwira ntchito, chifukwa ethylene gwero laulere lingathe kutulutsa polima homogeneous, sipadzakhala m'gulu la polypropylene apamwamba mu nthawi yochepa, ndi mbali ya malasha kuyenga mankhwala ndi zipangizo zina, chifukwa dongosolo latsopano chipangizo ndi wosakhazikika, teknoloji si okhwima ndi zifukwa zina kupanga kuyenga ndi malasha mankhwala makampani chitukuko khola, kotero zipangizo monga waya chojambula otsika kusungunuka copolymerization kugunda msika, si wachinsinsi monga mkulu-mapeto polypropylene. pakadali pano;M'tsogolomu, Sinopec ndi CNPC zidzakulitsa mphamvu zambiri chifukwa cha mbiri yawo yolemera komanso ndondomeko yokhazikika.Maonekedwe awo amayang'ana kwambiri kufunikira kwa msika wapamwamba.M'tsogolomu, mpikisano wa polypropylene wapamwamba udzapitirirabe kuzungulira mafuta awiri.

Pakufunidwa, polypropylene yapamwamba kwambiri pakadali pano ndiyofunika kwambiri pakusintha magalimoto.Kukula mwachangu kwamalingaliro opepuka agalimoto ndi magalimoto amphamvu atsopano kwapatsa mphamvu pamsika wosintha magalimoto.Chofunikira chachikulu pakukula ndipakati-mkulu-mkulu fusion copolymerization.Yachiwiri ndi yowonda jekeseni khoma.Mapaketi a Takeout aphatikizidwa muzochita zamagulu.Bizinesi yotengera zakudya yakula mwachangu kwambiri mothandizidwa ndi zochitika zaumoyo wa anthu.Chiwopsezo cha kukula chimaposa kukula konse kwa kufunikira kwa polypropylene.Makampani owonekera amagwiritsidwa ntchito kwambiri ndipo ali ndi chiyembekezo chachikulu.Amagwiritsidwa ntchito kwambiri m'matumba a kulowetsedwa kwachipatala, zida zamankhwala, zonyamula chidebe, zinthu zakhanda, ndi zina zambiri. Pakati pawo, nkhani zachipatala zowoneka bwino zimakhala pafupifupi 40% ya ndalama zonse zowonekera, ndikutsatiridwa ndi ma CD a chidebe.Chifukwa cha kukalamba chodabwitsa ku China ndi mmene mliri wamba, mandala zitsulo ayenera kusintha, ndipo panopa zoweta mandala msika kwambiri amadalira kunja, kotero pali malo lalikulu chitukuko cha msika zoweta m'tsogolo.Pomaliza, zida zapamwamba monga filimu ya binary ndi ternary copolymerization CPP ndi chitoliro chamadzi otentha ndizochepa pamsika chifukwa cha msika wawo wawung'ono komanso ntchito zochepa.Zogulitsa zapakhomo zimatha kuwerengera pafupifupi 50% ya gawo la msika, ndipo pakadali malo ambiri osewera pamsika wapakhomo.Mwachidule, tsogolo la kukula kwa mkulu-mapeto polypropylene mphamvu kukula ndi zosakwana mphamvu msika wonse wa polypropylene, ndi kufunika msika akadali ndi malo aakulu chitukuko, masanjidwe tsogolo la mkulu-mapeto polypropylene kafukufuku ndi kupanga chitukuko ndi. zofunikira.
