I te 1 o Hurae 2022, ka timata te hui tuatahi o te 300,000 tana.methyl methacrylate(i muri nei ka kiia ko te methyl methacrylate) Ko te kaupapa MMA a Henan Zhongkepu Raw and New Materials Co., Ltd. i whakahaerehia i roto i te Rohe Whanaketanga Ohaoha me te Hangarau o Puyang, e tohu ana i te tono o te huinga hou tuatahi o te hangarau katote wai catalytic ethylene MMA hangarau i hangaia motuhake e te CAS me Zhongyuan Dahua.Koinei hoki te tipu MMA ethylene tuatahi i whakaputaina i Haina.Mena ka pai te whakaurunga o nga taputapu ki roto i nga mahi, ka puta he huanga i roto i te hanga MMA ethylene a Haina, he tino paanga ki te umanga MMA.
Ko te waahanga tuarua MMA o te tukanga ethylene i Haina ka panuitia pea ki Shandong.Ko te whakaaro tuatahi ka whakauruhia ki roto i nga mahi i te takiwa o te tau 2024, a kei roto i te waahanga whakaaetanga tuatahi.Mena he pono te waeine, ka noho hei waahanga MMA tuarua o te tukanga ethylene i Haina, he mea tino nui ki te rereketanga o te tukanga whakaputa MMA i Haina me te whanaketanga o te ahumahi matū o Haina.
E ai ki nga raraunga e tika ana, kei reira nga tukanga whakaputa MMA e whai ake nei i Haina: te tukanga C4, te tukanga ACH, te whakapai ake i te tukanga ACH, te tukanga ethylene BASF me te tukanga ethylene Lucite.I te ao katoa, he whakaurunga ahumahi enei tukanga whakaputa.I Haina, kua hangaia te ture C4 me te ture ACH, engari ko te ture ethylene kaore ano kia tino mahia.
He aha te ahumahi matū o Haina e whakawhānui ana i tana tipu MMA ethylene?He whakataetae te utu whakangao o te MMA na te tikanga ethylene?
Tuatahi, kua hanga e te tipu MMA ethylene he papatea ki Haina me te taumata hangarau whakangao teitei.E ai ki te rangahau, e rua noa iho nga huinga ethylene MMA o te ao, kei Uropi me Amerika Te Tai Tokerau.He ngawari noa nga tikanga hangarau o nga waeine MMA ethylene.Ko te tere o te whakamahi ngota he nui ake i te 64%, a he nui ake te hua i etahi atu momo tukanga.Ko te BASF me te Lucite i whakahaere i nga rangahau hangarau me te whakawhanaketanga o nga taputapu MMA mo te mahi ethylene i te atatu, me te whakatutuki i te ahumahi.
Ko te waeine MMA o te tukanga ethylene e kore e uru ki nga rauemi mata waikawa, e arai ana hoki ki te iti o te waikura o nga taputapu, te ahua o te mahi hanga-taiao, me te roa o te waa mahi me te huringa.I tenei keehi, he iti ake te utu whakahekenga o te waeine MMA i roto i te mahi ethylene i te wa e mahi ana i era atu tukanga.
He kino ano nga taputapu Ethylene MMA.Tuatahi, me whai waahi tautoko mo nga tipu ethylene, ko te ethylene te nuinga o te hanga e nga tipu whakauru, na reira me tautoko te whanaketanga o nga hinonga whakauru.Mena ka hokona te ethylene, he rawakore te ohanga.Tuarua, e rua noa nga huinga taputapu MMA ethylene i te ao.Ko nga kaupapa a Haina e hanga ana e whakamahi ana i te hangarau o te Hainamana Academy of Sciences, me etahi atu hinonga kaore e taea te whiwhi ngawari me te whai hua te hangarau.Tuatoru, ko nga taputapu MMA o te tukanga ethylene he roa te rere o te tukanga, he nui te tauine haumi, te nui o te maota kei roto te wai para ka puta i roto i te tukanga whakaputa, me te utu maimoatanga o nga otaota e toru he nui.
Tuarua, ko te whakataetae utu o te waeine MMA te nuinga ka ahu mai i te ethylene tautoko, ko te ethylene o waho kaore he painga whakataetae.E ai ki te whakatewhatewha, ko te waeine MMA o te tikanga ethylene he 0.4294 tone o te ethylene, 0.387 tone methanol, 661.35 Nm ³ hau waihanga, 1.0578 tone o te chlorine masivesivá ka hangaia e te tauhohenga tahi, a kahore he hua waikawa methacrylic i roto i te tukanga whakaputa. .
E ai ki nga raraunga e tika ana i tukuna e Shanghai Yunsheng Chemical Technology Co., Ltd., ko te utu MMA mo te tikanga ethylene e tata ana ki te 12000 yuan/ton ka 8100 yuan/ton te ethylene, ko te methanol te 2140 yuan/ton, ko te hau waihanga he 1.95 yuan/ton. mita pūtoru, me te māota māota he 600 yuan/ton.Ina whakaritea ki te wa ano, he nui nga utu ture mo te tikanga C4 me te tikanga ACH.No reira, e ai ki nga ahuatanga o te maakete o naianei, kaore he whakataetae ohanga o te ethylene MMA.
Heoi, ko te hanga MMA ma te tikanga ethylene ka rite ki nga rauemi ethylene.Ko te Ethylene te tikanga mai i te pakaru o te naphtha, te whakahiato waro, me etahi atu. I tenei keehi, ko te whakataetae o te hanga MMA ma te tikanga ethylene ka pa te nuinga ki te utu o nga rawa ethylene.Mēnā ko te ethylene raw rauemi he mea tuku ake, me tatau i runga i te utu utu o te ethylene, ka tino pai ake te whakataetae utu o te ethylene MMA.
Tuatoru, ko te ethylene MMA e pau ana te nui o te maaota, a ko te utu me te hononga tautoko o te maaota ka whakatau i te matua ki te whakataetae utu o te ethylene MMA.E ai ki nga tukanga whakaputa o BASF me Lucite, me pau enei mahinga e rua i te nui o te maota.Mena he hononga tautoko te maaota, kaore e tika kia whakaarohia te utu o te maaota, ka tino pai ake te whakataetae utu o te ethylene MMA.
I tenei wa, kua aro nui te ethylene MMA na te whakataetae o nga utu whakaputa me te ngawari o te taiao whakahaere o te waahanga.I tua atu, ko nga whakaritenga mo te tautoko i nga rauemi mata e rite ana ki te ahuatanga whanaketanga o naianei o te umanga matū o Haina.Mena kei te tautoko te hinonga i te ethylene, te maaota me te hau whakahiato, katahi pea ko te ethylene MMA te huarahi whakangao whakataetae MMA tino utu i naianei.I tenei wa, ko te aratau whanaketanga o te umanga matū o Haina ko te nuinga o nga taputapu tautoko.I raro i tenei ahuatanga, ko te tikanga ethylene e hono ana ki te ethylene MMA ka noho hei kaupapa arotahi o te umanga.
