Guangdong Petrochemical's 800,000-ton/year full-density polyethylene chirimwa chirimwa chePetroChina chekutanga chakazara-density polyethylene chirimwa chine "musoro mumwechete nemiswe miviri" kurongeka kwemitsara miviri, uye zvakare ndiyo yechipiri yakazara-density polyethylene chirimwa chine hukuru hwekugadzira muChina. Chishandiso chinotora UNIPOL maitiro uye imwe-reactor gasi-chikamu fluidized bed process. Inoshandisa ethylene sechinhu chikuru mbishi uye inogona kugadzira gumi neshanu marudzi eLLDPE uye HDPE polyethylene zvinhu. Pakati pavo, iyo yakazara-density polyethylene resin particles yakagadzirwa ne polyethylene poda yakasanganiswa nemhando dzakasiyana-siyana dzekuwedzera, inopisa pakupisa kwepamusoro kusvika kune yakanyungudutswa, uye pasi pekuita kwemapatya-screw extruder uye pombi yakanyungudutswa yegiya, vanopfuura nepakati pe template uye vanogadziriswa pasi pemvura nemucheki. Granulation kugadzirwa. Pasi pemamiriro ekushanda akajairika, mutsara mumwe chete unogona kuburitsa matani 60.6 e polyethylene pellets paawa.
Zvinonzi kugadzirwa mutsetse muitiro anoshandisa ethylene sechinhu chikuru mbishi zvinhu uye butene-1 kana hexene-1 sezvo comonomer kuburitsa mutsara yakaderera-density uye imwe yepakati uye yakakwirira-density polyethylene granular resins. Sezvenguva yekutsikisa, mutsara wekugadzira wapedza zvakabudirira maitiro ese ekunatsa-polymerization-degassing-recycling-extrusion granulation, zviratidzo zvechigadzirwa zvinokwanisa, uye mutoro wekugadzira uri kuwedzera zvishoma nezvishoma. Guangdong Petrochemical's 800,000-ton/year full-density polyethylene plant line Ini ndakarongerwa kutanga kushanda mumazuva masere.
Iyo yakazara-density polyethylene plant yakatanga pa-site musi waSeptember 14, 2020. Munguva yekuvaka, iyo yakazara-density polyethylene sub-project department yakapa kutamba kwakazara kune zvakanakira "general-department" integrated management model, masimba akabatana kubva kumapato ese, akatakura zvizere kumberi kwemweya wemafuta uye mweya weDaqing, uye akatora pasina kumirira kurwisa kana nzvimbo yekutanga kurwisa. Kupisa kwepamusoro uye hunyoro hwepamusoro, kunaya uye dutu uye zvimwe zvinokanganisa. Bato rebato redhipatimendi diki rakapa kuita kwakazara kuita basa renhare yehondo, uye rakateedzana rakaronga makwikwi evashandi akadai se "kushanda nesimba kwemazuva makumi matanhatu", "kumhanya kwechina, uye kuhwina 3.30 ″. , akavaka mutsara wakasimba wekudzivirira kuchengetedza uye kunaka, akapera mu "kukurumidza" kwekuvaka kweprojekiti, pakati pechikumi 2, uye pakupedzisira akaziva chigadzirwa chepakati pechikumi. 2022, iyo yakatora mwedzi 21.5.
Muchikamu chekugadzirira kugadzirwa, zvinoenderana nemafungiro e "kupa kuisirwa asi kwete mutoro", uye kuenderera mberi nekudzidzira pfungwa ye "kubudirira kweprojekiti yemuridzi ndizvo zvinodiwa nenyika", iyo yakazara density polyethylene sub-purojekiti dhipatimendi yakawedzera kusimudzira manejimendi, uye moyo wekuisirwa - iyo yekupindura sisitimu Neiyo granulation system seyo musimboti, iyo yekuremerwa, kuyedza kutakura kweiyo mhepo kugadzirwa kwemhepo. catalyst loading of raw material refining, and joint debugging yezviridzwa zvemagetsi zvaitwa zvakarongeka. Vashandi vemanejimendi vakapindirana nekushanda kwepa-saiti zvakadzama kuti vaenderere mberi nekumhanyisa "kuferefeta kutatu uye zvisungo zvina" zvinhu zvekupedzisira uye zvinhu zvekutengesa zvePSSR. Iyo yakazara-density polyethylene sub-project department yakagara ichichengetedza "resonance panguva imwechete" nemuridzi. Dhizaini uye timu yekutyaira inonamatira kune saiti, iine pfungwa yebasa re "gara uine chokwadi", uye inoenda yese kubatirana kugadzirisa njodzi dzakavanzwa mu pre-yekuongorora maitiro, uye nekunyatso simbisa mamiriro ekugadzirira kweiyo catalyst system , jekiseni reiyo chromocene system, uye kuita kwakasimba kweakasiyana maitiro maparamita akaisa hwaro hwakasimba hwekutanga kwakabudirira kwechigadzirwa panguva imwe chete.
Muchikamu chekutanga chekushanda kwechirimwa, iyo yakazara-density polyethylene sub-purojekiti dhipatimendi ichasimbirira pakushanda nemoyo wese kuti ive nechokwadi chekuti chirimwa chinopinda munguva yekugadzirwa kwakagadzikana uye kushanda, kupedzisa kuongororwa kwekuita, uye kubatsira mukusimudzira kwepamusoro kwekambani.
