Mu 2022, China ethylene kupanga mphamvu anafika matani 49.33 miliyoni, waposa United States, kukhala dziko lonse ethylene sewerolo, ethylene wakhala ankaona ngati chizindikiro chachikulu kudziwa mlingo kupanga makampani mankhwala.Zikuyembekezeka kuti pofika chaka cha 2025, mphamvu yaku China yopangira ethylene ipitilira matani 70 miliyoni, zomwe zidzakwaniritse zosowa zapakhomo, kapena zochulukirapo.

Makampani a ethylene ndiye maziko amakampani a petrochemical, ndipo zinthu zake zimaposa 75% yazinthu zamafuta amafuta ndipo zimakhala ndi gawo lofunikira pazachuma chadziko.

Ethylene, propylene, butadiene, acetylene, benzene, toluene, xylene, ethylene oxide, ethylene glycol, ndi zina zotero. Zopangidwa ndi zomera za ethylene, ndizo zopangira zopangira mphamvu zatsopano ndi minda yatsopano.Kuphatikiza apo, mtengo wopangira ethylene wopangidwa ndi mabizinesi akulu ophatikizika oyenga ndi mankhwala ndi otsika.Poyerekeza ndi mabizinesi oyenga pamlingo womwewo, mtengo wowonjezera wazinthu zoyenga zophatikizika ndi mabizinesi amankhwala zitha kukulitsidwa ndi 25% ndipo kugwiritsa ntchito mphamvu kumatha kuchepetsedwa ndi 15%.

Polycarbonate, lithiamu batire olekanitsa, photovoltaic EVA (ethylene - vinilu acetate copolymer) akhoza kupangidwa kuchokera ethylene, alpha olefin, POE (polyolefin elastomer), carbonate, DMC (dimethyl carbonate), kopitilira muyeso-mkulu molecular kulemera polyethylene (UHMWPE) ndi zina zatsopano zakuthupi.Malinga ndi ziwerengero, pali mitundu 18 ya ethylene yotsika pansi yokhudzana ndi mphamvu zatsopano, zida zatsopano ndi mafakitale ena amphepo.Chifukwa chakukula mwachangu kwamphamvu zatsopano ndi mafakitale atsopano monga magalimoto amagetsi atsopano, ma photovoltaic ndi ma semiconductors, kufunikira kwa zinthu zatsopano kukukulirakulira.

Ethylene, monga pachimake pamakampani a petrochemical, atha kukhala ochulukirapo, zomwe zikuwonetsa makampani amafuta amafuta omwe akukumana ndi kukonzanso ndikusiyanitsidwa.Osati mabizinesi opikisana okha omwe amathetsa mabizinesi obwerera m'mbuyo, mphamvu zapamwamba zimathetsa mphamvu yakumbuyo, komanso kufa ndi kubadwanso kwamakampani otsogola a ethylene kumunsi kwa gawo lamakampani.

Makampani akuluakulu akhoza kusintha

Ethylene ikhoza kukhala yochulukirapo, kukakamiza kuyenga kophatikizika ndi mayunitsi amankhwala kuti aziwonjezera unyolo mosalekeza, kukulitsa unyolo ndikulimbitsa unyolo kuti apititse patsogolo mpikisano wagawo.Kuyambira mafuta obiriwira, ndikofunikira kupanga mwayi wophatikizana.Malingana ngati pali chiyembekezo chamsika kapena zogulitsa zomwe zili ndi msika wina, mzere udzakokedwa, womwe umafulumizitsanso kuthetsa opambana ndi otayika mu makampani onse a mankhwala.Kupanga ndi mawonekedwe azinthu zambiri zamakemikolo ndi zinthu zabwino zamankhwala zitha kubweretsa kusintha.Mitundu yopangira ndi masikelo idzachulukirachulukira, ndipo kuchuluka kwa mabizinesi kudzachepa pang'onopang'ono.

Zida zoyankhulirana, mafoni am'manja, zida zovala ndi zida zina zamagetsi zogula, luntha lamagalimoto, minda yanzeru yapanyumba ikukula mwachangu, zomwe zikuyendetsa kukula kwachangu kwa kufunikira kwa zida zatsopano zama mankhwala.Zida zatsopano zamakina izi ndi mabizinesi otsogola omwe ali ndi kakulidwe kakukula azisintha mwachangu, monga mphamvu 18 zatsopano ndi zinthu zatsopano zakutsitsidwa kwa ethylene.

A Fan Hongwei, wapampando wa Hengli Petrochemicals, adati momwe mungasungire mwayi wopikisana nawo ndikugwiritsira ntchito mfundo zatsopano zopezera phindu pamakina a ntchito yonse yamakampani ndi vuto lomwe liyenera kuyang'aniridwa.Tiyenera kupereka masewera onse pazabwino zamabizinesi akumtunda, kukulitsa ndi kukulitsa msika wamakampani padziko lonse lapansi kuti tipange zopindulitsa zatsopano, ndikuyesetsa kulimbikitsa kukulitsa kwazinthu zakumtunda kuti timange unyolo wabwino wamakampani opanga mankhwala.

Kang Hui New Material, wocheperapo wa Hengli Petrochemical, amatha kupanga 12 micron silicon kutulutsa filimu yoteteza batire ya lithiamu pa intaneti, Hengli Petrochemical imatha kupanga zinthu zambiri zamtundu wa 5DFDY, ndipo filimu yake yotulutsa MLCC imakhala yopitilira 65% yazopanga zapakhomo.

Kutenga kuyenga ndi kuphatikiza kwa mankhwala monga nsanja yotambasula molunjika komanso molunjika, timakulitsa ndi kulimbikitsa madera a niche ndikupanga chitukuko chophatikizika cha madera a niche.Kampani ikalowa mumsika, imatha kulowa m'mabizinesi otsogola.Mabizinesi 18 otsogola amphamvu zatsopano ndi zinthu zatsopano kunsi kwa ethylene atha kukumana ndi kusintha kwa umwini ndikusiya msika.

M'malo mwake, koyambirira kwa 2017, Shenghong Petrochemicals idakhazikitsa matani 300,000 / chaka EVA pogwiritsa ntchito zabwino zamakampani onse, kutha kwa 2024 kudzapanga pang'onopang'ono matani 750,000 a EVA, kuti apangidwe mu 2025, ndi ndiye, Shenghong Petrochemicals adzakhala lalikulu padziko lonse mkulu-mapeto EVA kotunga maziko.

China alipo mankhwala ndende, chiwerengero cha m'mapaki ndi mabizinezi m'zigawo zikuluzikulu mankhwala kachiwiri kuchepetsa pang'onopang'ono, Shandong oposa 80 mankhwala m'mapaki ngakhale pang'onopang'ono kuchepetsa theka, Zibo, Dongying ndi madera ena anaikira mabizinesi mankhwala adzachotsedwa theka.Kwa kampani, sikuti ndinu abwino, koma omwe akupikisana nawo ndi amphamvu kwambiri.

"Zimakhala zovuta kwambiri" kuchepetsa mafuta ndikuwonjezera chemistry

"Kuchepetsa mafuta ndi kuwonjezeka kwa mankhwala" kwakhala njira yosinthira mafuta am'nyumba ndi makampani opanga mankhwala.Mapulani amakono osinthira makina oyeretsera makamaka amatulutsa zida zopangira organic monga ethylene, propylene, butadiene, benzene, toluene ndi xylene.Kuchokera pazomwe zikuchitika panopa, ethylene ndi propylene akadali ndi malo opangira chitukuko, pamene ethylene akhoza kukhala ochuluka, ndipo zidzakhala zovuta kwambiri "kuchepetsa mafuta ndi kuonjezera mankhwala".

Choyamba, ndizovuta kusankha ntchito ndi zinthu.Choyamba, kufunikira kwa msika ndi kuchuluka kwa msika kumakhala kovuta kwambiri kusankha zinthu zokhala ndi ukadaulo wokhwima.Chachiwiri, pali kufunikira kwa msika ndi kuchuluka kwa msika, zinthu zina zimadalira kwathunthu zinthu zomwe zimatumizidwa kunja, sizikhala bwino ndiukadaulo wopanga, monga zida zapamwamba zopangira utomoni, mphira wapamwamba kwambiri, ulusi wapamwamba kwambiri komanso ma monomers, apamwamba kwambiri. -mapeto a carbon fiber, mapulasitiki a engineering, high-purrity electronic chemicals, etc .. Zonsezi zikuyang'anizana ndi vuto la "khosi", ndipo mankhwalawa sangathe kuyambitsa makina athunthu a teknoloji, ndipo akhoza kungowonjezera ndalama mu kafukufuku ndi chitukuko.

Makampani onse kuchepetsa mafuta ndikuwonjezera mankhwala, ndipo pamapeto pake kumabweretsa kuchuluka kwazinthu zama mankhwala.M'zaka zaposachedwa, ntchito yophatikizira yoyenga ndi kukonza mankhwala ikufuna "kuchepetsa mafuta ndikuwonjezera chemistry", ndipo mabizinesi oyenga ndi mankhwala omwe alipo amatenganso "kuchepetsa mafuta ndikuwonjezera chemistry" monga njira yosinthira ndi kukweza.M'zaka ziwiri kapena zitatu zapitazi, mphamvu yatsopano ya mankhwala ku China yatsala pang'ono kupitirira zaka khumi zapitazo.Makampani onse oyenga “akuchepetsa mafuta ndi kuwonjezereka kwa chemistry.Pambuyo pachimake pakupanga mphamvu zama mankhwala, mafakitale onse amatha kukhala ndi zochulukirapo kapena zochulukirapo.Zida zambiri zatsopano zamakina ndi mankhwala abwino zimakhala ndi misika yaying'ono, ndipo bola ngati pali luso laukadaulo, padzakhala kuthamangira, zomwe zimabweretsa kuchulukira komanso kutayika kwa phindu, komanso ngakhale pankhondo yotsika mtengo.
