Vinyl acetate (VAC) yakakosha organic makemikari raw material ine molecular formula yeC4H6O2, inozivikanwawo sevinyl acetate uye vinyl acetate.Vinyl acetate inonyanya kushandiswa mukugadzira polyvinyl doro, ethylene-vinyl acetate copolymer (EVA resin), ethylene-vinyl doro copolymer (EVOH resin), vinyl acetate-vinyl chloride copolymer (vinyl chloride resin), chena latex, acrylic fiber uye zvimwe zvigadzirwa.Inoshandiswa zvakanyanya muminda yesynthetic fiber, coating, slurry, firimu, kugadzirwa kwematehwe, kuvandudzwa kwevhu, uye ine tarisiro yakafara yebudiriro nekushandiswa.Nzira dzekuita dzevinyl acetate dzinosanganisira carbide acetylene nzira, gasi rechisikigo acetylene nzira uye petroleum ethylene nzira.Iyo carbide acetylene nzira inonyanya kushandiswa muChina, uye huwandu hwekugadzira hwe carbide acetylene nzira ichasvika 62% muna 2020.
Mumakore achangopfuura, kudiwa kwemusika kwevinyl acetate muChina kwakaratidza kukwira kumusoro maitiro.Zvinoenderana nehuwandu hweChina Chemical Fiber Indasitiri Association, muna 2016, iko kushandiswa kwevinyl acetate muChina kwaive matani 1.94 miriyoni, iyo yakawedzera kusvika 2.33 miriyoni matani muna 2019. Yakakanganiswa neCOVID-19 muhafu yekutanga ya2020 chiyero chekushanda kwemaindasitiri epasi chakaderera, zvichikonzera kuderera kudiki kwekushandiswa kunoratidzika kwevinyl acetate kune 2.16 miriyoni matani;Nekudzikamiswa kwedenda muhafu yechipiri yegore uye nekukasira kudzoreredza kwekugadzirwa kwehupfumi, kudiwa kwevinyl acetate kwakadzoka nekukurumidza kubva muhafu yechipiri ya2020 kusvika kuhafu yekutanga ya2021, mutengo wemusika wakakwira zvakanyanya, uye indasitiri yapora.
Iyo yekuda chimiro chevinyl acetate muChina yakagadzikana, ine polyvinyl doro, polyvinyl acetate, VAE lotion uye EVA resin sezvigadzirwa zvikuru.Muna 2020, chikamu chepolyvinyl doro mumidziyo yekushandisa mudzimba yevinyl acetate ichasvika 65%, uye iyo yakazara chikamu chepolyvinyl acetate, VAE lotion uye EAV resin ichave 31%.
Parizvino, China ine hukuru hukuru hwevinyl acetate munyika.Muna 2020, huwandu hweChina hwevinyl acetate huchasvika 2.65 miriyoni matani, inoverengera inosvika makumi mana muzana ehuwandu hwepasirese.Mumakore achangopfuura, iyo yekudzokera kumashure muChina vinyl acetate indasitiri yakadzikira zvishoma nezvishoma, uye huwandu hwepamberi hwakawedzerwa kuzadza gaka remusika.Nekuenderera mberi kwekusimudzira kweiyo indasitiri yekugovera chimiro, yeChina vinyl acetate kugadzirwa kwakaratidza kukura kwese maitiro.Zvinoenderana nehuwandu hweChina Chemical Fiber Indasitiri Association, iyo yepamba vinyl acetate kugadzirwa yakawedzera kubva 1.91 miriyoni matani muna 2016 kusvika 2.28 miriyoni matani muna 2019, ine musanganiswa wepagore kukura kwe5.98%;Muna 2020, nekuda kwemutengo wakaderera wemafuta epasi rose, mutengo wekugadzirwa kwemhiri kwemakungwa petroleum ethylene nzira yakaderedzwa, kutengwa kwevinyl acetate muChina kwakawedzera, uye kugadzirwa kwemukati kwevinyl acetate kwakadzikira kusvika mamirioni 1.99 matani;Kubva muhafu yechipiri ya2020, nekudzoreredza kwehupfumi hwenyika pamwe nekukwira kwemitengo yemafuta epasi rose, kugadzirwa kweindasitiri yemumba vinyl acetate kwave kudziya.
