Guangdong Petrochemical's 800,000-ton/gore yakazara-density polyethylene chirimwa ndicho chekutanga chakazara-density polyethylene chirimwa chine "musoro mumwechete nemiswe miviri" kurongeka kwemitsara miviri, uye zvakare ndiyo yechipiri yakazara-density polyethylene chirimwa chine hukuru hwekugadzira. China. 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 inogadzirwa nepolyethylene poda yakasanganiswa nemhando dzakasiyana dzekuwedzera, inopisa pakupisa kwepamusoro kusvika kune yakanyungudutswa, uye pasi pekuita kwemapatya-screw extruder uye pombi yakanyungudutswa yegiya. kupfuura nepa template uye inogadziriswa 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 chirimwa chakatanga panzvimbo paGunyana 14, 2020. Munguva yekuvaka, iyo yakazara-density polyethylene sub-project department yakapa kutamba kwakazara kune zvakanakira "general-department" integrated management model, akabatana masimba kubva. mapato ese, akatakura zvizere mweya wemafuta nemweya weDaqing, uye akatora danho rekurwisa pasina kumirira kana kuvimba nenzvimbo yeprojekiti. Kupisa kwepamusoro uye hunyoro hwepamusoro, kunaya uye dutu uye zvimwe zvinokanganisa. Bato rebato redhipatimendi diki rakapa kutamba kwakazara kune chinzvimbo chenhare yehondo, uye zvakatevedzana rakaronga makwikwi evashandi akadai se "kushanda nesimba kwemazuva makumi matanhatu", "kumhanya kwechina, uye kuhwina 3.30". , yakavaka mutsara wakasimba wekudzivirira kwekuchengeteka uye kunaka, yakapera "kukurumidza" kwekuvaka kweprojekiti, uye pakupedzisira yakaziva pakati-kuendeswa kwechigadzirwa musi waJune 27, 2022, iyo yakatora mwedzi 21.5.
Muchikamu chekugadzirira kugadzirwa, maererano nemafungiro e "kugovera kuiswa asi kwete mutoro", uye kuenderera mberi nekudzidzira pfungwa ye "kubudirira kwepurojekiti yemuridzi ndiyo inodiwa nenyika", iyo yakazara-density polyethylene sub- Dhipatimendi repurojekiti rakawedzera kusimudzira manejimendi, uye moyo wekuisirwa - iyo yekupindura sisitimu Neiyo granulation system seyakakosha, iyo yekuyera bvunzo kumhanya kwemayuniti mahombe, pickling uye kusimba kwemhepo kweiyo process pipeline system, catalys kurodha yekunatswa kwezvinhu. , uye kugadziriswa kwekubatana kwezviridzwa zvemagetsi kwakaitwa nenzira yakarongeka. 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. Iyo dhizaini uye timu yekutyaira inonamatira kune saiti, iine pfungwa yebasa re "gara uchizorora", uye inoenda kunze kushandira pamwe kugadzirisa njodzi dzakavanzika mu pre-test process, uye nekunyatso simbisa mamiriro ekugadzirira kweiyo catalyst system , Iko jekiseni rechromocene system, uye kunyatsoitwa kweakasiyana maitiro paramita kwakaisa hwaro hwakasimba hwekubudirira kwekutanga-kwemudziyo panguva imwe.
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.
