Mitengo yemusika wemakemikari yakaramba ichiderera kweinenge hafu yegore.Kuderera kwakadaro kwenguva refu, nepo mitengo yemafuta ichiramba yakakwirisa, yakonzera kusaenzana mukukosha kwezvizhinji zvinongedzo muketani yeindasitiri yemakemikari.Kuwanda kwematerminals mucheni yeindasitiri, ndiko kuwedzera kudzvanywa kwemutengo weketani yeindasitiri.Naizvozvo, zvigadzirwa zvakawanda zvemakemikari parizvino zviri kudhura zvakanyanya asi misika yevatengi inononoka, zvichikonzera kushomeka kwehupfumi hwezvigadzirwa zvemakemikari akawanda.
Mutengo wemusika wevinyl acetate wakaramba uchidzikira.Mumakore achangopfuura, mutengo wemusika wevinyl acetate wakadzikira kubva pa14862 yuan/ton muna Chikumi 2022 kusvika Chikumi 2023, uchiramba uchidzikira kwerinenge gore, nemutengo wakaderera uchidzika kusvika pa5990 yuan/ton.Kubva pamitengo yemakore mashoma apfuura, mutengo wakaderera munhoroondo wakaonekwa muna Kubvumbi 2020, mutengo wakaderera wakaonekwa pa5115 yuan/tani, mutengo wepamusoro wakaonekwa muna Mbudzi 2021, uye mutengo wepamusoro wakaonekwa pa16727 yuan/ton.

Kunyangwe mutengo wevinyl acetate wanga uchidzikira kwegore rakateedzana, purofiti yekugadzira yevinyl acetate inoramba yakakwira uye hupfumi hwekugadzira hwakanaka.Nei vinyl acetate ichigona kuchengetedza yakakwira mwero webudiriro?
Maitiro akasiyana ekugadzira evinyl acetate anoguma nekusiyana purofiti uye kurasikirwa
Zvinoenderana nekushandurwa kweiyo purofiti yevinyl acetate inogadzirwa ne ethylene nzira, iyo purofiti yevinyl acetate inogadzirwa ne ethylene nzira yakagara iri mune purofiti mumakore mashoma apfuura, iyo yepamusoro purofiti yasvika 50% kana kupfuura, uye avhareji yepurofiti inenge 15%.Zvinogona kuonekwa kuti ethylene yakavakirwa vinyl acetate yanga iri chigadzirwa chine pundutso mumakore maviri apfuura, ine budiriro yakanaka uye yakagadzikana purofiti.

Kubva pamaonero ecalcium carbide nzira vinyl acetate, mumakore maviri apfuura, kunze kwepurofiti yakakura kubva munaKurume 2022 kusvika Chikunguru 2022, dzimwe nguva dzese dzave mukurasikirwa.Kubva munaChikumi 2023, iyo purofiti yedanho re calcium carbide nzira vinyl acetate yaive yakapotsa 20% kurasikirwa, uye avhareji yepurofiti yekamuti yecalcium carbide nzira vinyl acetate mumakore maviri apfuura yaive kurasikirwa ne0.2%.Zvinogona kuonekwa kuti kubudirira kwe calcium carbide nzira yevinyl acetate yakashata, uye mamiriro ose ari kuratidza kurasikirwa.

Zvinogona kuonekwa kuti hachisi chinhu chakajairika kuti vinyl acetate ive padanho repamusoro.Iyo chete ethylene nzira yevinyl acetate kugadzirwa ikozvino iri mune purofiti mamiriro, nepo carbide nzira yakagara iri mukurasikirwa mumakore mashoma apfuura.
Ongororo yekuchengetedza yakakwira purofiti ye ethylene yakavakirwa vinyl acetate kugadzirwa
1. Chiyero chemitengo yezvigadzirwa zvinosiyana zvakasiyana mumagadzirirwo akasiyana ekugadzira.Mu ethylene yakavakirwa vinyl acetate kugadzirwa, iyo unit inoshandiswa ethylene ndeye 0.35 uye iyo unit inoshandiswa yeglacial acetic acid ndeye 0.72.Zvinoenderana neavhareji mutengo level muna Chikumi 2023, chikamu che ethylene mu ethylene yakavakirwa vinyl acetate kugadzirwa ingangoita 37%, nepo glacial acetic acid iri 45%.Naizvozvo, kushanduka kwemutengo kweglacial acetic acid kune kukanganisa kukuru pakuchinja kwemutengo we ethylene based vinyl acetate production, inoteverwa ne ethylene.
Kana iri mari yecalcium carbide nzira yevinyl acetate, calcium carbide inosvika 47% yemutengo wecalcium carbide nzira yevinyl acetate, uye glacial acetic acid inosvika 35% yemutengo wecalcium carbide nzira yevinyl acetate.Nokudaro, mu calcium carbide nzira yevinyl acetate, kuchinja kwemutengo we calcium carbide kune simba guru pamutengo, iyo yakasiyana zvikuru nekugadzirisa mari ye ethylene nzira.
2. Kuderera kukuru kwezvinhu zvakasvibiswa ethylene uye glacial acetic acid zvakakonzera kuderera kukuru kwemari.Maererano nemashoko akakodzera, mugore rapfuura, mutengo weCFR Northeast Asia ethylene wakaderera ne33%, uye mutengo weglacial acetic acid wakaderera ne32%.Zvisinei, mutengo wekugadzirwa kwevinyl acetate uchishandisa nzira ye calcium carbide inonyanya kuderedzwa nemutengo we calcium carbide.Mugore rapfuura, mutengo we calcium carbide wakadzikira ne25%.
Naizvozvo, kubva pakuona kwemaitiro maviri akasiyana ekugadzira, iyo mbishi mari ye ethylene nzira vinyl acetate yakadzikira zvakanyanya, uye kuderedzwa kwemutengo kwakakura kupfuura iyo ye calcium carbide nzira.

3. Kunyange zvazvo mutengo wevinyl acetate wakaderera, kuderera hakusi kwakakosha semamwe makemikari.Mugore rapfuura, mutengo wevinyl acetate wakaderera ne59%, iyo inoratidzika seyakanyanya kuderera, asi mutengo wemamwe makemikari wakaderera zvakanyanya.
Vinyl acetate yakagara ichichengetedza imwe purofiti margin, kunyanya nekuda kwekudzikiswa kwemutengo kunokonzerwa nekudzikira kwemitengo yezvinhu, pane kutsigirwa kwemusika wevatengi pamitengo yayo.Iyi ndiyowo mamiriro azvino ekukosha kwekutapurirana mune vinyl acetate indasitiri chain.Kubva pamamiriro ezvinhu aripo emusika wemakemikari weChinese munguva pfupi, zvakaoma kushandura zvakanyanya mamiriro asina kusimba emusika wemakemikari weChina pasina mikuru-yepamusoro yevatengi misika yekusimudzira mitemo.Zvinotarisirwa kuti kukosha kweketani yevinyl acetate irambe ichichengetedza yakadzika yekufambisa logic, uye zvinotarisirwa kuti purofiti yekugadzira mune ramangwana musika wevatengi, kunyanya ye polyethylene neEV zvigadzirwa, ichachengetwa nekudzikisa purofiti yevinyl. acetate.
