Isitshalo se-polyethylene esigcwele amathani angu-800,000 ngonyaka se-Guangdong Petrochemical siyisitshalo sokuqala se-polyethylene esigcwele amatani esinohlelo lwemigqa emibili "yekhanda elilodwa nemisila emibili", futhi futhi siyisitshalo sesibili se-polyethylene esigcwele amatani esinekhono lokukhiqiza elikhulu kunawo wonke eShayina. Le divayisi isebenzisa inqubo ye-UNIPOL kanye nenqubo yombhede wegesi wesigaba esisodwa. Isebenzisa i-ethylene njengezinto ezisetshenziswayo eziyinhloko futhi ingakhiqiza izinhlobo ezingu-15 zezinto ze-polyethylene ze-LLDPE ne-HDPE. Phakathi kwazo, izinhlayiya ze-resin ze-polyethylene esigcwele amatani zenziwe nge-polyethylene powder exutshwe nezinhlobo ezahlukene zezithasiselo, ezishiswa ekushiseni okuphezulu ukuze zifinyelele esimweni esincibilikisiwe, futhi ngaphansi kwesenzo se-extruder enama-twin-screw kanye nephampu yegiya elincibilikisiwe, zidlula kuthempulethi futhi zicutshungulwa ngaphansi kwamanzi yi-cutter. Ukwakheka kwe-granulation. Ngaphansi kwezimo zokusebenza ezijwayelekile, umugqa owodwa ungakhiqiza amathani angu-60.6 ama-pellet e-polyethylene ngehora.
Kubikwa ukuthi inqubo yomugqa wokukhiqiza isebenzisa i-ethylene njengezinto eziyinhloko zokusetshenziswa kanye ne-butene-1 noma i-hexene-1 njenge-comonomer ukukhiqiza ama-resin e-polyethylene granular aqondile kanye nama-resin aphakathi nendawo naphezulu. Ngesikhathi sokunyathelisa, umugqa wokukhiqiza usuqede ngempumelelo yonke inqubo yokuhlanza i-polymerization-degassing-recycling-extrusion granulation, izinkomba zomkhiqizo ziyafaneleka, futhi umthwalo wokukhiqiza uyanda kancane kancane. Umugqa wesitshalo se-polyethylene esigcwele esingu-800,000-ton/ngonyaka i-Guangdong Petrochemical uhlelelwe ukuqala ukusebenza ezinsukwini eziyi-8.
Isitshalo se-polyethylene esigcwele saqala endaweni ngoSepthemba 14, 2020. Ngesikhathi sokwakha, umnyango wephrojekthi encane ye-polyethylene egcwele wanikeza izinzuzo zemodeli yokuphatha ehlanganisiwe "yomnyango jikelele", amabutho ahlangene avela kuzo zonke izinhlangothi, waqhubekisela phambili ngokugcwele umoya kawoyela nomoya we-Daqing, futhi wathatha isinyathelo sokuhlasela ngaphandle kokulinda noma ukuthembela endaweni yephrojekthi. Ukushisa okuphezulu kanye nomswakama ophezulu, imvula kanye nesiphepho kanye neminye imiphumela emibi. Igatsha leqembu lomnyango wephrojekthi encane lanikeza indima ephelele yenqaba yempi, futhi ngokulandelana lahlela uchungechunge lwemincintiswano yabasebenzi efana "nokusebenza kanzima izinsuku ezingama-60", "ukugijimela ikota yesine, nokuwina ama-3.30″., lakha umugqa oqinile wokuzivikela wokuphepha nekhwalithi, laphelelwa "ukusheshisa" kokwakhiwa kwephrojekthi, futhi ekugcineni laqaphela ukulethwa kwedivayisi phakathi noJuni 27, 2022, okwathatha izinyanga ezingama-21.5.
Esigabeni sokulungiselela ukukhiqiza, ngokuhambisana nesimo sengqondo "sokudlulisela ukufakwa kodwa hhayi umthwalo wemfanelo", nokuqhubeka nokusebenzisa umqondo wokuthi "impumelelo yephrojekthi yomnikazi yilokho okufunwa yizwe", umnyango wephrojekthi encane ye-polyethylene egcwele uthuthukise ukuphathwa, kanye nenhliziyo yokufaka - uhlelo lokuphendula Njengoba uhlelo lwe-granulation luyisisekelo, ukuhlolwa komthwalo kwamayunithi amakhulu, ukuhluza kanye nokuqina komoya kohlelo lwepayipi lenqubo, ukulayishwa kwe-catalyst kokuhluzwa kwezinto zokusetshenziswa, kanye nokulungiswa kwamathuluzi kagesi okuhlangene kwenziwe ngendlela ehlelekile. Abasebenzi bokuphatha bahlanganiswe nemisebenzi ejulile endaweni ukuze basheshise kakhulu "uphenyo oluthathu kanye nezinqumo ezine" izinto zokugcina kanye nezinto zokuthengisa ze-PSSR. Umnyango wephrojekthi encane ye-polyethylene egcwele uhlale "uphendulana ngemvamisa efanayo" nomnikazi. Ithimba lokuklama nokushayela linamathela endaweni, linomuzwa wesibopho "sokuhlala uqiniseka", futhi lisebenza konke okusemandleni ukubambisana ukuxazulula izingozi ezifihliwe enkambisweni yangaphambi kokuhlolwa, futhi liqinisekisa ngokucophelela isimo sokulungiselela uhlelo lwe-catalyst, ukufakwa kohlelo lwe-chromocene, kanye nokusetshenziswa okuqinile kwemingcele ehlukahlukene yenqubo kubeke isisekelo esiqinile sokuqaliswa ngempumelelo kwedivayisi ngesikhathi esisodwa.
Esigabeni sokuqala sokusebenza kwesitshalo, umnyango wephrojekthi encane ye-polyethylene egcwele uzogcizelela ukukhonza ngenhliziyo yonke ukuqinisekisa ukuthi isitshalo singena enkathini yokukhiqizwa nokusebenza okuzinzile, siqede ukuhlolwa kokusebenza, futhi sinegalelo ekuthuthukisweni kwekhwalithi ephezulu yenkampani.
