Ko te tipu polyethylene kiato-katoa 800,000-tana/tau a Guangdong Petrochemical te tipu polyethylene kiato-katoa tuatahi a PetroChina me te whakaritenga raina-rua "kotahi te upoko me te rua ngā hiku", ā, koia hoki te tuarua o ngā tipu polyethylene kiato-katoa me te kaha whakaputa nui rawa atu i Haina. Ka whakamahia e te taputapu te tukanga UNIPOL me te tukanga moenga wai-wāhanga-kotahi-tauhohenga. Ka whakamahia te ethylene hei rauemi mata matua, ā, ka taea te whakaputa i te 15 momo rauemi polyethylene LLDPE me HDPE. I roto i ēnei, ko ngā matūriki kapia polyethylene kiato-katoa he mea hanga ki te paura polyethylene i konatunatua ki ngā momo tāpiri rerekē, ka whakamahanahia ki te pāmahana teitei kia tae ki te āhua rewa, ā, i raro i te mahi a te extruder takirua-whiu me te papu taputapu rewa, ka haere rātou i roto i te tauira ka tukatukahia i raro i te wai e te kaitapahi. Te hanganga kirikiri. I raro i ngā tikanga mahi noa, ka taea e te raina kotahi te whakaputa i te 60.6 tana o ngā pire polyethylene ia haora.
E ai ki ngā pūrongo, ko te tukanga whakaputa e whakamahi ana i te ethylene hei rauemi mata matua, me te butene-1, te hexene-1 rānei hei comonomer hei whakaputa i ngā kapia polyethylene matotoru-iti me ētahi kapia polyethylene matotoru-waenga me te matotoru-teitei. I te wā i tāia ai, kua oti pai i te raina whakaputa te tukanga katoa o te whakamahine-polymerization-degassing-recycling-extrusion granulation, kua tohua ngā tohu hua, ā, kei te piki haere te kawenga whakaputa. Kua whakaritea kia tīmata te mahi i roto i ngā rā e 8 te raina tipu polyethylene matotoru-katoa 800,000-tana/tau a Guangdong Petrochemical.
I tīmata te tipu polyethylene matotoru-katoa i te papaanga i te 14 o Hepetema, 2020. I te wā o te hanganga, i tino whakamahia e te tari kaupapa iti polyethylene matotoru-katoa ngā painga o te tauira whakahaere whakauru "tari whānui", i whakakotahi i ngā ope mai i ngā rōpū katoa, i kawe katoa i te wairua hinu me te wairua Daqing, ā, i tīmata ki te whakaeke me te kore e tatari, e whakawhirinaki rānei ki te wāhi o te kaupapa. Te pāmahana teitei me te haumākū teitei, te ua me te awhiowhio me ētahi atu pānga kino. I tino whakamahia e te peka rōpū o te tari kaupapa iti te tūranga o te pā pakanga, ā, i whakarite i ngā whakataetae mahi pēnei i te "mahi kaha mō ngā rā 60", te "oma tere mō te hauwhā tuawhā, me te toa 3.30". , i hanga he rārangi parepare pakari mō te haumaru me te kounga, i pau te "whakaterenga" o te hanganga kaupapa, ā, i te mutunga ka tutuki te tukunga waenga o te taputapu i te 27 o Hune, 2022, i roa mō te 21.5 marama.
I te wāhanga whakarite whakaputa, i runga anō i te whakaaro "tuku i te tāutanga engari kaua te kawenga", me te whai tonu i te ariā "ko te angitu o te kaupapa a te rangatira te mea e hiahiatia ana e te ao", i whakapai ake te tari kaupapa iti polyethylene kiato-katoa i te whakahaere, me te ngākau o te tāutanga - te pūnaha urupare. Me te pūnaha granulation hei matua, kua oti te whakamātautau kawenga o ngā waeine nui, te pickling me te hau-pupuhi o te pūnaha paipa tukatuka, te utaina o te whakakorikori o te whakamahine rauemi mata, me te patuiro tahi o ngā taputapu hiko i runga i te tikanga tika. I whakaurua ngā kaimahi whakahaere ki ngā mahi i te papaanga kia tere ake ai te tere ake o ngā tūemi whakamutunga "e toru ngā rangahau me ngā whakataunga e whā" me ngā tūemi hoko PSSR. Kua mau tonu te tari kaupapa iti polyethylene kiato-katoa i te "hauora kotahi" me te rangatira. Ka piri tonu te tīma hoahoa me te tīma taraiwa ki te pae, me te whakaaro he "okioki tonu", ā, ka mahi tahi ki te whakaoti i ngā tūponotanga huna i roto i te tukanga whakamātautau-mua, me te āta whakaū i te mana whakarite o te pūnaha whakakorikori. Ko te werohanga o te pūnaha chromocene, me te whakatinanatanga pakari o ngā tawhā tukanga rerekē kua whakatakoto i tētahi turanga pakari mō te tīmatanga angitu o te taputapu i te wā kotahi.
I te wāhanga tuatahi o te whakahaere o te wheketere, ka tohe te tari kaupapa iti polyethylene kiato-katoa ki te mahi me te ngākau pono kia uru te wheketere ki tētahi wā whakaputa me te whakahaere pumau, kia oti ai te aromatawai mahi, ā, kia whai wāhi atu ki te whanaketanga kounga teitei o te kamupene.
