Chomera cha polyethylene cha Guangdong Petrochemical cholemera matani 800,000 pachaka ndi chomera choyamba cha polyethylene cha PetroChina chokhala ndi mizere iwiri ya "mutu umodzi ndi michira iwiri", ndipo ndi chomera chachiwiri cha polyethylene chokhala ndi mphamvu yayikulu kwambiri yopanga ku China. Chipangizochi chimagwiritsa ntchito njira ya UNIPOL ndi njira ya gas-phase fluidized bed process. Chimagwiritsa ntchito ethylene ngati chinthu chachikulu ndipo chimatha kupanga mitundu 15 ya LLDPE ndi HDPE polyethylene. Pakati pawo, tinthu ta polyethylene tokhala ndi mphamvu zonse timapangidwa ndi ufa wa polyethylene wosakanikirana ndi mitundu yosiyanasiyana ya zowonjezera, zotenthedwa kutentha kwambiri kuti zifike pamlingo wosungunuka, ndipo pogwiritsa ntchito chotulutsira ma screw awiri ndi pampu yosungunuka ya gear, zimadutsa mu template ndikukonzedwa pansi pa madzi ndi chodulira. Kupanga kwa granulation. Munthawi yogwira ntchito yanthawi zonse, mzere umodzi ukhoza kupanga matani 60.6 a ma polyethylene pellets pa ola limodzi.
Zanenedwa kuti njira yopangira mzere imagwiritsa ntchito ethylene ngati zopangira zazikulu ndi butene-1 kapena hexene-1 ngati comonomer kuti ipange ma resins a polyethylene granular otsika komanso apakatikati komanso apamwamba. Pofika nthawi yofalitsa nkhani, mzere wopangira wamaliza bwino ntchito yonse yoyeretsera-polymerization-degassing-recycling-extrusion granulation, zizindikiro za malonda zili zoyenerera, ndipo katundu wopangira ukuwonjezeka pang'onopang'ono. Mzere wa fakitale ya polyethylene wolemera matani 800,000 pachaka wa Guangdong Petrochemical ukukonzekera kuyamba kugwira ntchito m'masiku 8.
Chomera cha polyethylene chodzaza ndi anthu chinayamba pamalopo pa Seputembala 14, 2020. Panthawi yomanga, dipatimenti ya polojekiti ya polyethylene yodzaza ndi anthu inapereka zonse zabwino za chitsanzo chogwirizanitsa cha "dipatimenti yayikulu", magulu ogwirizana ochokera mbali zonse, inapititsa patsogolo mzimu wamafuta ndi mzimu wa Daqing, ndipo inayamba kuukira popanda kudikira kapena kudalira malo a polojekitiyo. Kutentha kwambiri ndi chinyezi chambiri, mvula yamkuntho ndi zotsatira zina zoyipa. Nthambi ya chipani cha dipatimenti ya polojekitiyi inapereka zonse zomwe zinali pa udindo wa linga lankhondo, ndipo motsatizana inakonza mipikisano yambiri ya antchito monga "kugwira ntchito molimbika kwa masiku 60", "kuthamanga kotala lachinayi, ndikupambana 3.30″., inamanga mzere wolimba woteteza chitetezo ndi khalidwe, inatha "kufulumira" kwa ntchito yomanga, ndipo pamapeto pake inapeza pakati pa ntchitoyo pa June 27, 2022, yomwe inatenga miyezi 21.5.
Mu gawo lokonzekera kupanga, mogwirizana ndi malingaliro akuti "kupereka kukhazikitsa koma osati udindo", ndikupitiliza kugwiritsa ntchito lingaliro lakuti "kupambana kwa polojekiti ya mwiniwake ndiye chomwe dziko likufuna", dipatimenti ya pulojekiti ya polyethylene yodzaza ndi kuchuluka kwa anthu idapititsa patsogolo kayendetsedwe ka ntchito, ndi mtima wa kukhazikitsa - njira yoyankhira. Ndi dongosolo la granulation ngati maziko, kuyesa kwa katundu wa mayunitsi akuluakulu, kutsuka ndi kutseka mpweya wa dongosolo la mapaipi, kutsitsa zinthu zopangira, ndi kukonza zida zamagetsi molumikizana kwachitika mwadongosolo. Ogwira ntchito oyang'anira adalumikizana ndi ntchito zomwe zikuchitika pamalopo mozama kuti apititse patsogolo "kafukufuku katatu ndi kutsimikiza kwa zinthu zinayi" ndi zinthu zogulitsa za PSSR. Dipatimenti ya pulojekiti ya polyethylene yodzaza ndi kuchuluka kwa anthu nthawi zonse yakhala ikugwira ntchito "yofanana pafupipafupi" ndi mwiniwake. Gulu lopanga ndi kuyendetsa limatsatira malowa, ndi lingaliro la udindo wa "khalani otsimikiza nthawi zonse", ndipo limayesetsa kuthandizana kuthetsa zoopsa zobisika mu njira yoyesera isanayambe, ndikutsimikizira mosamala momwe dongosolo lothandizira limakhalira. Kulowetsa dongosolo la chromocene, ndi kukhazikitsa mwamphamvu magawo osiyanasiyana a njira kwakhazikitsa maziko olimba kuti chipangizocho chiyambe bwino nthawi imodzi.
Pa gawo loyamba la ntchito ya fakitale, dipatimenti ya pulojekiti ya polyethylene yodzaza ndi anthu ambiri idzalimbikira kutumikira ndi mtima wonse kuti iwonetsetse kuti fakitaleyo ilowa munthawi yokhazikika yopanga ndi kugwira ntchito, kumaliza kuwunika magwiridwe antchito, komanso kuthandizira pakukula kwabwino kwa kampaniyo.
