ʻO Guangdong Petrochemical 800,000-ton/makahiki piha-density polyethylene mea kanu ʻo ia ka PetroChina piha piha piha polyethylene mea kanu me "hoʻokahi poʻo a me elua huelo" papalua laina laina, a oia no hoi ka lua piha-density polyethylene mea kanu me ka nui loa hana mana i loko o. Kina. Hoʻohana ka mea hana i ke kaʻina UNIPOL a me ke kaʻina moena hoʻoheheʻe hoʻokahi-reactor. Hoʻohana ʻo ia i ka ethylene ma ke ʻano he kumu maka nui a hiki ke hana i 15 mau ʻano LLDPE a me HDPE polyethylene. I waena o lākou, ua hana ʻia nā ʻāpana polyethylene resin piha piha i ka pauka polyethylene i hui pū ʻia me nā ʻano mea hoʻohui like ʻole, i hoʻomehana ʻia i kahi wela kiʻekiʻe e hiki ai i kahi moku i hoʻoheheʻe ʻia, a ma lalo o ka hana a kahi twin-screw extruder a me kahi pahu hoʻoheheʻe ʻia, lākou. e hele i loko o kahi mamana a ua hana ʻia ma lalo o ka wai e kahi mea ʻoki. Hoʻokumu granulation. Ma lalo o nā kūlana hana maʻamau, hiki i kahi laina hoʻokahi ke hana i 60.6 tons o polyethylene pellets i kēlā me kēia hola.
Ua hōʻike ʻia ʻo ke kaʻina hana laina e hoʻohana i ka ethylene ma ke ʻano he kumu kumu a me ka butene-1 a i ʻole hexene-1 ma ke ʻano he comonomer e hana i ka laina haʻahaʻa haʻahaʻa a me kekahi mau resins polyethylene granular medium a kiʻekiʻe. E like me ka manawa paʻi, ua hoʻokō pono ka laina hana i ke kaʻina holoʻokoʻa o ka hoʻomaʻemaʻe-polymerization-degassing-recycling-extrusion granulation, ua kūpono nā hōʻailona huahana, a ke piʻi mālie nei ka ukana hana. ʻO Guangdong Petrochemical 800,000-ton/makahiki piha-density polyethylene plant line I hoʻomaka e hoʻomaka i ka hana i nā lā 8.
Ua hoʻomaka ka mea kanu polyethylene piha piha ma ka pūnaewele i ka lā 14 o Kepakemapa 2020. I ka wā o ke kūkulu ʻana, ua hāʻawi ke keʻena sub-project full-density polyethylene sub-project i ka pāʻani piha i nā pono o ka "general-department" integrated management model, united forces mai. nā ʻaoʻao a pau, lawe piha i ka ʻuhane ʻaila a me ka ʻuhane Daqing, a lawe i ka manaʻo e hoʻouka me ke kali ʻole a hilinaʻi paha ma kahi o ka papahana. ʻO ka wela kiʻekiʻe a me ka haʻahaʻa kiʻekiʻe, ka ua a me ka typhoon a me nā hopena ʻino ʻē aʻe. Hāʻawi ka lālā pāʻina o ka ʻoihana sub-project i ka pāʻani piha i ka hana o ka pā kaua, a ua hoʻonohonoho i nā ʻano hoʻokūkū hana e like me ka "hana ikaika no nā lā 60", "sprinting no ka hapahā ʻehā, a lanakila 3.30". , kūkulu i kahi laina pale paʻa no ka palekana a me ka maikaʻi, holo i waho o ka "wikiwiki" o ke kūkulu ʻana i ka papahana, a ʻike hope i ka waena o ka hoʻouna ʻana o ka hāmeʻa ma Iune 27, 2022, ʻo 21.5 mau mahina.
I ka papa hana hoʻomākaukau, e like me ka manaʻo o "ka hāʻawi ʻana i ka hoʻonohonoho ʻana akā ʻaʻole ke kuleana", a me ka hoʻomau ʻana i ka hoʻomaʻamaʻa ʻana i ka manaʻo o "ka kūleʻa o ka papahana o ka mea nona ka makemake o ka honua", ka piha-density polyethylene sub- papahana oihana hou upgrade i ka hooponopono, a me ka naau o ka hoʻokomo - ka pane nenoaiu Me ka granulation nenoaiu e like me ke kumu, ka haawe ho'āʻo holo o nui wae, pickling a me ka ea-tightness o ke kaʻina pipeline nenoaiu, catalyst hoʻouka o maka mea hoʻomaʻemaʻe. , a ua hoʻokō pono ʻia ka debugging hui o nā mea uila. Hoʻopili nā limahana hoʻokele me nā hana ma ka pūnaewele i ka hohonu e wikiwiki hou i nā "ʻekolu noiʻi a me nā hoʻoholo ʻehā" hope loa a me nā mea kūʻai PSSR. Ua mālama mau ke keʻena sub-project polyethylene piha piha i ka "resonance ma ke alapine like" me ka mea nona. ʻO ka hoʻolālā a me ka hui hoʻokele e pili ana i ka pūnaewele, me ka manaʻo o ke kuleana o ka "hoʻomaha mau", a hele i nā mea a pau e hui pū e hoʻoponopono i nā pilikia huna i loko o ke kaʻina hana hoʻāʻo mua, a hoʻopaʻa pono i ke kūlana hoʻomākaukau o ka ʻōnaehana catalyst , ʻO ka hoʻokomo ʻana i ka ʻōnaehana chromocene, a me ka hoʻokō pono ʻana i nā ʻāpana kaʻina hana like ʻole i kau i kahi kumu paʻa no ka hoʻomaka ʻana o ka hāmeʻa i ka manawa hoʻokahi.
I ka pae mua o ka hana mea kanu, e koi aku ka piha-density polyethylene sub-project oihana e lawelawe me ka naau holookoa no ka hooiaio ana e komo ka mea kanu i ka manawa o ka hana paa a me ka hana ana, e hoopau ana i ka loiloi hana, a e kokua i ka ulu maikai o ka hui.
