【Nhanganyaya】Muna Chikunguru, zvigadzirwa zviri muchikamu cheindasitiri cheacetone zvakaratidza kudzikira kwakanyanya. Kusawirirana kwekudiwa kwezvinhu uye kutapurirana kwemitengo kwakaramba kuri izvo zvakakonzera kudzikira kwemitengo yemusika. Zvisinei, pasinei nekuderera kwemitengo yezvigadzirwa zveindasitiri, kunze kwekuwedzera kushoma kwekurasikirwa nepurofiti yeindasitiri, purofiti yeMMA neisopropanol yakaramba iri pamusoro pemutsetse we breakeven (kunyangwe purofiti yavo yakaderedzwawo zvakanyanya), nepo zvimwe zvigadzirwa zvese zvakaramba zviri pasi pemutsetse we breakeven.
Zvigadzirwa muchikamu chemaindasitiri cheacetone zvakaratidza kudzikira kwetsika muna Chikunguru
Zvigadzirwa muchikamu chemaindasitiri cheacetone zvakaderera mwedzi uno. Kusawirirana kwekudiwa kwezvinhu uye kutapurirana kwemitengo kwakaderera ndizvo zvakakonzera kudzikira kwemusika. Panyaya yekuderera kwemusika, acetone yakaona kudzikira kwemwedzi nemwedzi kweinenge 9.25%, ichitanga padanho rekutanga muchikamu chemaindasitiri. Kuwanikwa kweacetone mumusika wemuno muna Chikunguru kwakaratidza kuwedzera kwemaitiro: kune rumwe rutivi, mamwe mabhizinesi akambomisa kugadzirwa akatangisazve, akadai saYangzhou Shiyou; kune rumwe rutivi, Zhenhai Refining & Chemical yakatanga kutengesa zvigadzirwa kunze kwenyika musi waChikunguru 10, izvo zvakaodza mwoyo vari mukati meindasitiri, zvichisundira pfungwa yekukurukurirana kwemusika pasi. Zvisinei, mitengo payakaramba ichidzikira, vane mari vakasangana nekumanikidzwa kwemitengo, uye vamwe vakaedza kukwidza mitengo yavo, asi kuwedzera kwacho kwakanga kusina kugadzikana, uye huwandu hwekutengeserana hwakakundikana kupa rutsigiro.
Zvigadzirwa zve acetone zvakaderera zvakanyanya. Pakati pazvo, mitengo yeavhareji ye bisphenol A, isopropanol, ne MIBK yakadzikira ne5%, pa -5.02%, -5.95%, uye -5.46% zvichiteerana. Mitengo yezvinhu zvekugadzira phenol ne acetone yakadzikira zvakanyanya, saka mutengo wakakundikana kutsigira indasitiri ye bisphenol A. Pamusoro pezvo, mitengo yekushanda kweindasitiri ye bisphenol A yakaramba yakakwira, asi kudiwa kwakatevera zvishoma nezvishoma; zvichikonzerwa nekumanikidzwa kwekuwanikwa kwezvinhu uye kudiwa kwezvinhu, kuderera kweindasitiri kwakawedzera.
Kunyangwe musika we isopropanol mumwedzi uyu wakagamuchira rutsigiro rwakanaka kubva pazvinhu zvakaita sekuvharwa kweNingbo Juhua, kudzikiswa kwemutoro waDalian Hengli, uye kunonoka kwekutakura zvinhu zvekutengeserana mudzimba, divi rekudiwa kwacho rakanga risina kusimba. Uyezve, mitengo ye acetone yezvinhu zvisina kugadzirwa yakaderera pasi pe5,000 yuan/tani, zvichisiya vanhu vari mukati meindasitiri vasina chivimbo chakakwana, avo vainyanya kutengesa nemitengo yakaderera, asi huwandu hwekutengeserana hwakanga husina rutsigiro, zvichikonzera kudzikira kwemusika.
Kuwanikwa kweMIBK kwakaramba kwakakwana, mamwe mafekitori achiri kutarisana nekumanikidzwa kwekutumira zvinhu. Mitengo yemitengo yakaderedzwa nenzvimbo yekutaurirana kwekutengeserana, nepo kudiwa kwacho kwakadzikama, zvichikonzera kudzikira kwemitengo yemusika. Avhareji yemutengo weMMA mumusika wekutanga weEast China yakaderera pasi pe10,000-yuan mwedzi uno, nekudzikira kwemwedzi nemwedzi kwe4.31% mumutengo wepakati pamwedzi. Kudzikira kwekuda panguva yekuzorora ndiyo yaive chikonzero chikuru chekudzikira kwemusika weMMA.
Purofiti yezvigadzirwa zvemaindasitiri yaive isina kusimba
Muna Chikunguru, purofiti yezvigadzirwa muchikamu chemaindasitiri cheacetone yaive isina kusimba. Parizvino, zvigadzirwa zvakawanda muchikamu chemaindasitiri zviri mumamiriro ekuti zvinhu zvakawanda zviripo asi kuteverwa kwezvinodiwa hakukwani; pamwe chete nekutapurirana kwemitengo kwakashata, izvi zvave zvikonzero zvekurasikirwa kwezvigadzirwa zvechikamu chemaindasitiri. Mumwedzi uyu, MMA neisopropanol chete ndizvo zvakaramba zvichiwana purofiti iri pamusoro pemutsetse we breakeven, nepo zvimwe zvigadzirwa zvese zvakaramba zviri pasi payo. Mwedzi uno, purofiti yese yechikamu chemaindasitiri yaive ichiri kunyanya kuunganidzwa muindasitiri yeMMA, nepurofiti yese yepfungwa inosvika 312 yuan/ton, nepo kurasikirwa kwepurofiti yese yepfungwa yeindasitiri yeMIBK kwakawedzera kusvika 1,790 yuan/ton.
Zvigadzirwa zviri muchikamu cheindasitiri cheacetone zvinogona kushanda mumhando shoma dzekuchinja-chinja muna Nyamavhuvhu
Zvinotarisirwa kuti zvigadzirwa zviri muchikamu cheindasitiri cheacetone zvinogona kushanda mumhando shoma dzekuchinja-chinja muna Nyamavhuvhu. Mumazuva gumi ekutanga aNyamavhuvhu, zvigadzirwa zvechikamu cheindasitiri zvinonyanya kutarisa pakufungisisa zvibvumirano zvenguva refu, nechido chidiki chekutenga zvinhu zviri mumusika. Huwandu hwekutengeserana huchapa rutsigiro rushoma kuzvigadzirwa zvechikamu cheindasitiri. Pakati nepakati nepakupera kwemazuva gumi, sezvo zvimwe zvinangwa zvekutenga zvinhu zviri pasi zvichiwedzera uye musika we "Golden September" wava kusvika, kudiwa kwekupedzisira kunogona kudzoreredzwa, uye huwandu hwekutengeserana hunogona kuumba rutsigiro rwakati rwemitengo. Zvisinei, maererano nehuwandu hwekuchinja-chinja mwedzi uno, tarisiro dzinoramba dziri shoma.
