Vinyl acetate (VAc), izwi kandi nka vinyl acetate cyangwa vinyl acetate, ni amazi atagira ibara kandi abonerana mubushyuhe bwicyumba hamwe nigitutu.Nka kimwe mu bikoresho bikoreshwa cyane mu nganda zikoreshwa mu nganda, VAc irashobora kubyara polyvinyl acetate resin (PVAc), inzoga za polyvinyl (PVA), polyacrylonitrile (PAN) n’ibindi bikomokaho binyuze muri polymerisation cyangwa copolymerisation hamwe n’abandi ba monomor.Ibikomokaho bikoreshwa cyane mubwubatsi, imyenda, imashini, imiti nubutaka.

Muri rusange Isesengura rya Vinyl Acetate Urunigi

Inzira yo hejuru ya vinyl acetate yinganda zigizwe ahanini nibikoresho fatizo nka acetylene, acide acike, Ethylene na hydrogène, nibindi. Uburyo nyamukuru bwo gutegura bugabanijwemo ubwoko bubiri: bumwe nuburyo bwa peteroli ya Ethylene, bukozwe muri Ethylene, acide acike na hydrogen, kandi bigira ingaruka ku ihindagurika ryibiciro bya peteroli.Imwe muriyo ni ugutegura acetylene na gaze kariside cyangwa kariside ya calcium, hanyuma hamwe na synthesis ya acetike ya vinyl acetate, gaze naturel igiciro gito ugereranije na kariside ya calcium.Hasi cyane ni ugutegura inzoga za polyvinyl, latex yera (polyvinyl acetate emulsion), VAE, EVA na PAN, nibindi, inzoga za polyvinyl nicyo gikenewe cyane.

1 、 Hejuru yibikoresho fatizo bya vinyl acetate

Acide acetike nurufunguzo rwibanze rwibanze rwa VAE, kandi ikoreshwa ryayo rifitanye isano rikomeye na VAE.Imibare iragaragaza ko kuva mu mwaka wa 2010, Ubushinwa bugaragara ko bukoresha aside ya asike muri rusange bugenda bwiyongera, gusa mu 2015 n’inganda zazamutse mu ntera kandi impinduka zikenewe zaragabanutse, 2020 igera kuri toni miliyoni 7.2, yiyongeraho 3,6% ugereranije na 2019. Hamwe vinyl acetate yamanuka nibindi bicuruzwa ubushobozi bwimiterere ihinduka, igipimo cyimikoreshereze cyiyongereye, inganda za acide acike muri rusange zizakomeza kwiyongera.

Kubijyanye na porogaramu zo hasi, 25,6% ya acide acetike ikoreshwa mugukora PTA (acide terephthalic acide), 19.4% ya acide acetike ikoreshwa mugukora vinyl acetate, naho 18.1% ya acide acetike ikoreshwa mukubyara Ethyl acetate.Mu myaka yashize, imiterere yinganda zikomoka kuri acide acike yagiye ihinduka neza.Vinyl acetate ikoreshwa nkimwe mubice byingenzi bikoreshwa munsi ya acide acike.

2. Imiterere yo hasi ya vinyl acetate

Vinyl acetate ikoreshwa cyane cyane mu gukora inzoga za polyvinyl na EVA, n'ibindi. Ethylene vinyl acetate - Ethylene copolymer (EVA), nibindi. Polimeri zavuyemo zirashobora gukoreshwa nkibikoresho bifatika, impapuro cyangwa imyenda ingana, amarangi, wino, gutunganya uruhu, emulisiferi, firime zishonga amazi, hamwe nubutaka bwubutaka mumiti, imyenda It ifite uburyo bwinshi bwo gukoresha mubikoresho bya shimi, imyenda, inganda zoroheje, gukora impapuro, ubwubatsi n’imodoka.Amakuru yerekana ko 65% ya vinyl acetate ikoreshwa mukubyara inzoga za polyvinyl naho 12% ya vinyl acetate ikoreshwa mugukora acide polyvinyl.

Isesengura ryibihe byisoko rya vinyl acetate

1 capacity Ubushobozi bwo kubyara Vinyl acetate nigipimo cyo gutangira

Kurenga 60% byubushobozi bwa vinyl acetate ku isi byibanda mu karere ka Aziya, mu gihe Ubushinwa butanga umusaruro wa vinyl acetate bugera kuri 40% by’umusaruro rusange ku isi kandi ni cyo gihugu kinini ku isi gitanga vinyl acetate.Ugereranije nuburyo bwa acetylene, uburyo bwa Ethylene nubukungu kandi bwangiza ibidukikije, hamwe nibicuruzwa byiza.Kubera ko ingufu z’inganda z’imiti mu Bushinwa zishingiye cyane cyane ku makara, umusaruro wa vinyl acetate ushingiye ahanini ku buryo bwa acetylene, kandi ibicuruzwa ni bike cyane.Ubushobozi bwo gukora vinyl acetate yo mu gihugu bwagutse cyane muri 2013-2016, mugihe butagihinduka muri 2016-2018.2019 Uruganda rwa vinyl acetate mu Bushinwa rugaragaza imiterere y’ubushobozi bw’ubushobozi, hamwe n’ubushobozi burenze urugero muri calcium karbide acetylene itunganyirizwa hamwe n’inganda nyinshi.2020, Ubushinwa butanga umusaruro wa vinyl acetate ingana na toni miliyoni 2.65 / mwaka, umwaka ushize.

2 use Gukoresha Vinyl acetate

Ku bijyanye n’imikoreshereze, vinyl acetate y’Ubushinwa muri rusange yerekana ihindagurika ry’izamuka, kandi isoko rya vinyl acetate mu Bushinwa ryagutse cyane kubera ubwiyongere bw’ibikenerwa kuri EVA yo hepfo, n'ibindi. Amakuru yerekana ko, usibye muri 2018 , Ubushinwa bukoresha vinyl acetate bitewe n’izamuka ry’ibiciro bya acide acike, ibicuruzwa byagabanutse, kuva mu 2013 Ubushinwa bw’isoko rya vinyl acetate bwiyongereye ku buryo bwihuse, ibicuruzwa byiyongereye uko umwaka utashye, kuko muri 2020 hasi yageze kuri toni miliyoni 1.95, kwiyongera ya 4.8% ugereranije na 2019.

3 、 Igiciro cyo hagati yisoko rya vinyl acetate

Urebye ibiciro by'isoko rya vinyl acetate, byatewe n'ubushobozi burenze, ibiciro by'inganda byakomeje kuba byiza muri 2009-2020.2014 kubera kugabanuka kw'ibicuruzwa byo hanze, ibiciro by'ibicuruzwa byiyongereye cyane, ibigo byimbere mu gihugu byagura cyane umusaruro, bikaviramo ubushobozi bukabije.Ibiciro bya Vinyl acetate byagabanutse cyane muri 2015 na 2016, naho muri 2017, kubera politiki yo kurengera ibidukikije, ibiciro by’inganda byazamutse cyane.2019, kubera itangwa rihagije ku isoko ryo hejuru ya acide acike no kugabanuka gukenerwa mu nganda zubaka zo hasi, ibiciro by’inganda byagabanutse cyane, kandi muri 2020, byibasiwe n’icyorezo, igiciro cy’ibicuruzwa cyaragabanutse cyane, kandi guhera muri Nyakanga 2021, ibiciro ku isoko ryiburasirazuba byageze ku barenga 12.000 Izamuka ry’ibiciro ni rinini, biterwa ahanini n’ingaruka zamakuru meza y’ibiciro bya peteroli ya peteroli yo hejuru ndetse n’isoko rusange ry’isoko rito ryatewe no guhagarika uruganda cyangwa gutinda.

Incamake ya Ethyl Acetate

Ethyl acetate y’inganda z’abashinwa igice cy’ibiti bine bya Sinopec bifite ubushobozi bwa toni miliyoni 1.22 / umwaka, bingana na 43% by’igihugu, naho itsinda rya Anhui Wanwei rifite toni 750.000 / umwaka, bingana na 26.5%.Igice cyashowe mu mahanga Nanjing Celanese toni 350.000 / ku mwaka, bingana na 12%, naho igice cyigenga Imbere muri Mongoliya Shuangxin na Ningxia Dadi hamwe na toni 560.000 / umwaka, bingana na 20%.Muri iki gihe uruganda rukora vinyl acetate ruherereye mu majyaruguru y’iburengerazuba, Ubushinwa bw’Uburasirazuba n’Amajyepfo y’Uburengerazuba, aho ubushobozi bw’amajyaruguru y’iburengerazuba bugera kuri 51,6%, Ubushinwa bw’iburasirazuba bungana na 20.8%, Ubushinwa bw’Amajyaruguru bugera kuri 6.4% naho Uburengerazuba bw’Amajyepfo bugera kuri 21.2%.

1 、 EVA kumanuka ikenera kwiyongera

EVA kumanuka ya vinyl acetate irashobora gukoreshwa nka firime ya PV selile.Nk’uko umuyoboro mushya w'ingufu ku isi ubivuga, EVA iva muri Ethylene na vinyl acetate (VA) monomers ebyiri na reaction ya copolymerisation, igice kinini cya VA muri 5% -40%, kubera imikorere myiza yacyo, ibicuruzwa bikoreshwa cyane mu ifuro, bikora firime yamenetse, gupakira firime, ibicuruzwa bivamo inshinge, imiti ivanga hamwe nudusimba, insinga na kabili, firime ya fotovoltaque selile encapsulation firime hamwe nudushushe dushyushye, nibindi. , hamwe no gutandukanya ingano ya moderi ya fotovoltaque, igipimo cyikubye kabiri-ibirahuri module yinjira byiyongereye ku buryo bugaragara, icyifuzo cy’amafoto y’amashanyarazi kirenze iterambere ryateganijwe, bigatuma iterambere rya EVA ryiyongera.Biteganijwe ko toni 800.000 z’ubushobozi bwa EVA zizashyirwa mu bikorwa mu 2021. Nkurikije ibigereranyo, ubwiyongere bwa toni 800.000 z’ubushobozi bw’umusaruro wa EVA buzatuma buri mwaka kwiyongera kwa toni 144.000 by’ibisabwa na vinyl acetate, bizatera imbere buri mwaka ya toni 103.700 za acide acike ikenewe.

2 、 Vinyl acetate birenze ubushobozi, ibicuruzwa byo mu rwego rwo hejuru biracyakenewe gutumizwa mu mahanga

Ubushinwa bufite ubushobozi bwa vinyl acetate muri rusange, kandi ibicuruzwa byo mu rwego rwo hejuru biracyakenewe gutumizwa mu mahanga.Kugeza ubu, itangwa rya vinyl acetate mu Bushinwa rirenze icyifuzo, hamwe n'ubushobozi burenze urugero ndetse n'umusaruro ukabije ushingiye ku byoherezwa mu mahanga.Kuva kwagura umusaruro wa vinyl acetate mu 2014, ibicuruzwa byoherezwa mu mahanga vinyl acetate mu Bushinwa byiyongereye ku buryo bugaragara, kandi bimwe mu bicuruzwa byatumijwe mu mahanga byasimbuwe n’ubushobozi bw’imbere mu gihugu.Byongeye kandi, ibyoherezwa mu Bushinwa ahanini ni ibicuruzwa byo mu rwego rwo hasi, mu gihe ibitumizwa mu mahanga ahanini ari ibicuruzwa byo mu rwego rwo hejuru.Kugeza ubu, Ubushinwa buracyakeneye gushingira ku bicuruzwa biva mu mahanga biva mu mahanga, kandi inganda za vinyl acetate ziracyafite umwanya wo kwiteza imbere ku isoko ry’ibicuruzwa byo mu rwego rwo hejuru.
