Kuongorora kwakazara kweVinyl acetate indasitiri ketani

Kukwira kumusoro kweVinyl acetate indasitiri inonyanya kuumbwa neyakagadzirwa, ethycation maitiro, etrocic acid uye hydrogen, uye inokanganiswa nekuchinjika kwemitengo isina kuchena. Imwe ndeyekugadzirira kweacetylene negesi rechisikigo kana calcium carbide, uye ipapo uye acetic acid synthesis ye vinyl acetate, gasi rechisikigo mutengo wakakwira kupfuura calcium carbide. Downstream iri kugadzirira kwePolyvinyl doro, chena Latex (Polyvinyl acetate emulsion), vae, Eva naPan, nezvimwewo, zveti, ndedzipi polyvinyl doro ndiro doro.

1, kumusoro kwezvinhu zvishandiso zve vinyl acetate

Acetic acid ndiyo kiyi yehunhu rakakwira kumusoro kweVae, uye kunwa kwaro kunoruramisa kwakasimba naVae. Data ratidza kuti kubva 2010, China inooneka yekushandisa acetic acids yekudzikira, uye kuwanda kwemakumi matatu nemashanu.

Panyaya yekunyepedzera masisitimu, 25.6% yeAcetic acid inoshandiswa kugadzira PTA (yakacheneswa terephthac acid) Mumakore achangopfuura, iyo indasitiri muenzaniso weacetic acid inodonha yakagadzikana. Vinyl acetate inoshandiswa seimwe yeanonyanya kukosha sownstrepa application zvikamu zve acetic acid.

2. Synstream chimiro che vinyl acetate

Vinyl acetate inonyanya kushandiswa kugadzira Polyvinyl Doro neEva, Vanyori veChinese, vanogona kunge vari polyvinyl doro (peva), Eva MaAinhesives, pepa kana machira emachira, mapepa, mapepa emapepa, zvinyorwa zvemamita Data inoratidza kuti 65% yeVinyl acetate inoshandiswa kugadzira polyvinyl doro uye 12% yeVinyl acetate inoshandiswa kugadzira polyvinyl acetate.

Kuongororwa kwemamiriro ezvinhu azvino eVinyl acetate musika

1, vinyl acetate zvigadzirwa zvekugadzira uye kutanga-up rate

Vanopfuura 60% yenyika yeVinyl acetate Production Conction inoiswa munzvimbo yeAsia, nepo china yeVinyl acetate maaccount yekugadzira kwehuwandu hwekugadzira nyika uye ndiyo yakanyanya kuwanda yeVinyl vinyl acetate kuburitsa nyika. Kuenzaniswa neiyo acetylene nzira, nzira yeEthylene iri hupfumi uye nharaunda ine hushamwari, nekukwira kwakakwirira kwechigadzirwa. Sezvo simba resimba reChemical indasitiri inondirava pamarasha, kugadzirwa kweVinyl acetate inonyanya kuve yakavakirwa pane iyo acetylene nzira, uye zvigadzirwa zvakadzika zvakaderera. Domestic vinyl acetate zvigadzirwa zvekugadzira yakawedzera zvakanyanya mukati megore ragore ra 2013-2016, uchiramba asingachinjiki panguva ye 2016-2018. 2019 China's Vinyl acetate indasitiri inopa chimiro chakarongeka 2020, China's Vinyl acetate yekugadzira huwandu hwemamirioni 2,65, gore, goridhe-pagore-gore.

2, vinyl acetate kudhinda

Kusvika pakushayiwa kweChina, China's vinyl acetate seyakavhenekesa kumusoro kwechidimbu Rumutsira nekukurumidza, kupindira kwasimuka gore rimwe nerimwe, se2020 yakaderera yasvika 1.95 miriyoni manhamba, kuwedzera kwe4,8% kuenzaniswa ne1909.

3, iyo avhareji mutengo we vinyl acetate musika

Kubva pamaonero eVinyl acetate mitengo yemusika, inokanganiswa nekuwedzera simba, mitengo yemashiripiti yakaramba yakagadzikana muna 2009-2020. 2014 neKugovana Kwekunze Kupa Contraction, mitengo yechigadzirwa yakawedzera zvakanyanya, mabhishi epamba anowedzera kuwedzera kugadzirwa, zvichikonzera kuwanda kukuru. Vinyl acetate mitengo yakawira zvakanyanya muna 2015 na 2016, uye muna 2017, inokanganiswa nemitengo yezvemamiriro ekunze, mitengo yechigadzirwa yechigadzirwa yakasimuka zvakanyanya. 2019, nekuda kwekuwana zvakakwana mumusika wekumusoro wenyaya yekuvaka muChirungu. Yakadzika yemusika inopihwa inokonzerwa neimwe fekitori yekuvhara kana kunonoka.

Kuongorora kweEthyl acetate makambani

Ethyl accetate eChinese Segment Sinopec's zvinomera zveSinopec Iyo yekudyara-inodyarwa chikamu chelanjing celande 350,000 matani / gore, accounting ye12%, uye yakavanzika chikamu chemoyo Iyo yazvino epamba vinyl acetate vanogadzira inonyanya kuwanikwa muchamhembe kwakadziva kumadokero, nechokumaodzanyemba kwakadziva kumadokero kwe20.8%, North China accounting

Kuongororwa kweVinyl acetate Outlook

1, Eva kudzikisira Kukura Kukura

Eva Downstream we vinyl acetate inogona kushandiswa sePV Scels Incapsulation Firimu. Zvinoenderana neNew Loss Energy Network, Eva kubva kuEthylene uye Vinyl Account etc. 2020 ye photovoltaic subsidies mugore rapfuura, vakawanda veModule Vagadziri veModule Saizi, kudiwa kweModule Modully Zvinotarisirwa kuti mazana masere ezviuru eEver kugona kugadzirwa muna 2021

2, vinyl acetate kunyanyisa, zvigadzirwa zvepamusoro-magumo zvichiri kuda kuendeswa kunze kwenyika

China ine zvese zvakavanzika zveVinyl acetate, uye zvakakwirira-mugumo zvigadzirwa zvichiri kuda kuendeswa kunze kwenyika. Parizvino, iyo yekugovera yeVinyl acetate muChina inodarika zvinodiwa, nekuwanda kwekunyanyisa uye kuwandisa kugadzirwa kunovimba nexport yekufambisa. Sezvo kuwedzerwa kweVinyl acetate Production Kugadzira muna 2014, China vinyl acetate kutumira kunze kwenyika kwakawedzera zvakanyanya, uye zvimwe zvigadzirwa zvakatengwa kunze kwenyika zvakadzoserwa nekugadzira mudzimba. Mukuwedzera, China kutumira kunze kwenyika inonyanya kuderera-magumo zvigadzirwa, nepo kunze kwenyika kuri kunyanya zvigadzirwa zvepamusoro-zvinopera. Parizvino, China ichiri kufanira kuvimba nekukasira kune yakakwira vinyl vinyl acetate zvigadzirwa, uye vinyl acetate indasitiri ichine nzvimbo yekuvandudza mumusika wakakwira-mugumo wechigadzirwa.
