Isityalo se-polyethylene esigcweleyo seGuangdong Petrochemical esiziitoni ezingama-800,000 ngonyaka sisityalo sokuqala se-polyethylene esigcweleyo sePetroChina esinomgca ophindwe kabini "wentloko enye nemisila emibini", kwaye sikwasisityalo sesibini se-polyethylene esigcweleyo esinomthamo omkhulu wemveliso eTshayina. Esi sixhobo samkela inkqubo ye-UNIPOL kunye nenkqubo yebhedi yegesi yesigaba esinye. Sisebenzisa i-ethylene njengezinto ezisetyenziswa kakhulu kwaye sinokuvelisa iintlobo ezili-15 zezinto ze-polyethylene ze-LLDPE kunye ne-HDPE. Phakathi kwazo, amasuntswana e-polyethylene egcweleyo enziwe ngomgubo we-polyethylene oxutywe neentlobo ezahlukeneyo zezithako, ezifudunyezwa kubushushu obuphezulu ukuze zifikelele kwimeko enyibilikisiweyo, kwaye phantsi kwesenzo se-extruder ye-twin-screw kunye nepompo yegiya enyibilikisiweyo, zidlula kwitemplate kwaye zicutshungulwa phantsi kwamanzi ngumsiki. Ukwakheka kwe-granulation. Phantsi kweemeko zokusebenza eziqhelekileyo, umgca omnye unokuvelisa iitoni ezingama-60.6 zeepellets ze-polyethylene ngeyure.
Kuxelwe ukuba inkqubo yomgca wemveliso isebenzisa i-ethylene njengezinto eziphambili zokwenza imveliso kunye ne-butene-1 okanye i-hexene-1 njenge-comonomer ukuvelisa i-linear low-density kunye nezinye ii-resin ze-polyethylene granular eziphakathi neziphezulu. Ngexesha lokushicilelwa, umgca wemveliso ugqibe ngempumelelo yonke inkqubo yokucoca i-polymerization-degassing-recycling-extrusion granulation, izalathisi zemveliso ziyafaneleka, kwaye umthwalo wemveliso uyanda kancinci kancinci. Umgca wesityalo se-polyethylene opheleleyo we-800,000-ton/ngonyaka we-Guangdong Petrochemical ucwangciselwe ukuqala ukusebenza kwiintsuku ezi-8.
Isityalo se-polyethylene esinoxinano olupheleleyo saqala kwindawo leyo nge-14 kaSeptemba 2020. Ngexesha lokwakhiwa, isebe leprojekthi encinci ye-polyethylene elinoxinano olupheleleyo lanika amandla apheleleyo kwiingenelo zomzekelo wolawulo oludibeneyo "lwesebe jikelele", imikhosi edibeneyo evela kuwo onke amaqela, laqhubela phambili ngokupheleleyo umoya weoyile kunye nomoya weDaqing, laza lathatha inyathelo lokuhlasela ngaphandle kokulinda okanye ukuthembela kwindawo yeprojekthi. Ubushushu obuphezulu kunye nokufuma okuphezulu, imvula kunye nenkanyamba kunye nezinye iziphumo ezimbi. Isebe leqela lesebe leprojekthi encinci lanika amandla apheleleyo indima yenqaba yemfazwe, kwaye ngokulandelelana laququzelela uthotho lwemincintiswano yabasebenzi efana "nokusebenza nzima iintsuku ezingama-60", "ukubaleka kwikota yesine, kunye nokuphumelela i-3.30″. , lakha umgca oqinileyo wokuzikhusela ngokhuseleko kunye nomgangatho, laphelelwa "kukukhawulezisa" ukwakhiwa kweprojekthi, kwaye ekugqibeleni lafumanisa ukuhanjiswa kwesixhobo phakathi nge-27 kaJuni 2022, eyathatha iinyanga ezingama-21.5.
Kwinqanaba lokulungiselela imveliso, ngokuhambelana nesimo sengqondo "sokunikezela ngofakelo kodwa hayi uxanduva", nokuqhubeka nokusebenzisa ingcamango "yempumelelo yeprojekthi yomnini yinto efunwa lihlabathi", isebe leprojekthi encinci ye-polyethylene egcweleyo liphucule ngakumbi ulawulo, kunye nentliziyo yofakelo - inkqubo yokuphendula. Ngenkqubo ye-granulation njengeyona nto iphambili, uvavanyo lomthwalo lweeyunithi ezinkulu, ukucola kunye nokuqina komoya kwenkqubo yepayipi yenkqubo, ukulayishwa kwe-catalyst yokucocwa kwezinto eziluhlaza, kunye nokulungiswa kwezixhobo zombane ezidibeneyo kwenziwe ngendlela ehlelekileyo. Abasebenzi bolawulo badibene nemisebenzi enzulu kwindawo ukuze bakhawulezise ngakumbi "uphando oluthathu kunye nezigqibo ezine" kunye nezinto zokuthengisa ze-PSSR. Isebe leprojekthi encinci ye-polyethylene egcweleyo lihlala ligcina "ukuhambelana rhoqo" nomnini. Iqela loyilo kunye nokuqhuba linamathela kwindawo, liziva linoxanduva "lokuhlala liqinisekile", kwaye lisebenza nzima ukusombulula iingozi ezifihlakeleyo kwinkqubo yangaphambi kovavanyo, kwaye liqinisekisa ngononophelo imeko yokulungiselela inkqubo ye-catalyst, ukufakwa kwenkqubo ye-chromocene, kunye nokusetyenziswa ngokungqongqo kweeparamitha ezahlukeneyo zenkqubo kuye kwabeka isiseko esiqinileyo sokuqaliswa ngempumelelo kwesixhobo ngaxeshanye.
Kwinqanaba lokuqala lokusebenza kwesityalo, isebe leprojekthi ye-polyethylene egcweleyo liza kugxininisa ekusebenzeni ngentliziyo yonke ukuqinisekisa ukuba isityalo singena kwixesha lemveliso nokusebenza okuzinzileyo, sigqibezele uvavanyo lokusebenza, kwaye sinegalelo kuphuhliso lomgangatho ophezulu lwenkampani.
