I-Vinyl acetate (VAC) iyi-organic acetate yamakhemikhali ebalulekile ephilayo enefomula yamangqamuzana ye-C4H6O2, eyaziwa nangokuthi i-vinyl acetate ne-vinyl acetate.I-Vinyl acetate isetshenziswa kakhulu ekukhiqizeni i-polyvinyl alcohol, i-ethylene-vinyl acetate copolymer (EVA resin), i-ethylene-vinyl alcohol copolymer (EVOH resin), i-vinyl acetate-vinyl chloride copolymer (vinyl chloride resin), i-latex emhlophe, i-acrylic fiber kanye eminye imikhiqizo.Isetshenziswa kabanzi emkhakheni we-synthetic fiber, ukugqoka, i-slurry, ifilimu, ukucubungula isikhumba, ukuthuthukiswa kwenhlabathi, futhi inethemba elibanzi lokuthuthuka nokusetshenziswa.Imizila yenqubo ye-vinyl acetate ihlanganisa indlela ye-carbide acetylene, indlela ye-acetylene yegesi yemvelo kanye nendlela ye-petroleum ethylene.Indlela ye-carbide acetylene isetshenziswa kakhulu e-China, futhi amandla okukhiqiza we-carbide acetylene indlela azofinyelela ku-62% ngo-2020.
Eminyakeni yamuva nje, isidingo semakethe se-vinyl acetate e-China sibonise umkhuba okhuphukayo jikelele.Ngokwezibalo ze-China Chemical Fiber Industry Association, ngonyaka ka-2016, ukusetshenziswa okusobala kwe-vinyl acetate e-China bekungamathani ayizigidi eziyi-1.94, okukhuphuke kwafinyelela kumathani ayizigidi ezi-2.33 ngonyaka ka-2019. izinga lokusebenza kwezimboni ezansi nomfula laliphansi, okuholele ekwehleni okuncane kokusetshenziswa okusobala kwe-vinyl acetate kuya kumathani ayizigidi ezingu-2.16;Ngokuzinza kwesimo sobhubhane engxenyeni yesibili yonyaka kanye nokusimama ngokushesha kokukhiqizwa komnotho, isidingo se-vinyl acetate silulame ngokushesha ukusuka engxenyeni yesibili ka-2020 kuya engxenyeni yokuqala ka-2021, intengo yemakethe yenyuka kakhulu, futhi imboni yasimama.
Isakhiwo esifunwayo se-vinyl acetate e-China sizinzile uma kuqhathaniswa, sine-polyvinyl alcohol, i-polyvinyl acetate, i-VAE lotion ne-EVA resin njengemikhiqizo eyinhloko.Ngo-2020, ingxenye yotshwala be-polyvinyl esakhiweni esisetshenziswa ekhaya se-vinyl acetate izofinyelela ku-65%, kanti ingxenye ephelele ye-polyvinyl acetate, i-VAE lotion ne-EAV resin izoba ngu-31%.
Njengamanje, i-China inomthamo omkhulu we-vinyl acetate emhlabeni.Ngo-2020, umthamo waseChina we-vinyl acetate uzofinyelela kumathani ayizigidi ezi-2.65, okuzobalelwa ku-40% wawo wonke amandla omhlaba.Eminyakeni yamuva nje, amandla okubuyela emuva embonini ye-vinyl acetate yaseChina ahoxile kancane kancane, futhi umthamo othuthukile wengeziwe ukugcwalisa igebe lemakethe.Ngokuthuthukiswa okuqhubekayo kwesakhiwo sokuhlinzeka ngemboni, ukukhiqizwa kwe-vinyl acetate yaseChina kubonise inkambiso yokukhula iyonke.Ngokwezibalo ze-China Chemical Fiber Industry Association, ukukhiqizwa kwe-vinyl acetate yasekhaya kukhuphuke kusuka kumathani ayizigidi eziyi-1.91 ngo-2016 kuya kumathani ayizigidi ezi-2.28 ngo-2019, ngesilinganiso sokukhula saminyaka yonke esingu-5.98%;Ngo-2020, ngenxa yentengo ephansi kawoyela yamazwe ngamazwe, izindleko zokukhiqiza ze-petroleum ethylene indlela yaphesheya kwezilwandle zancishiswa, ukungeniswa kwe-vinyl acetate eChina kwanda, futhi ukukhiqizwa kwasekhaya kwe-vinyl acetate kwehla kuya kumathani ayizigidi ezingu-1.99;Kusukela engxenyeni yesibili ka-2020, ngokusimama komnotho womhlaba kanye nokukhuphuka kwamanani kawoyela wamazwe omhlaba, ukukhiqizwa kwemboni yasekhaya ye-vinyl acetate kuye kwafudumala.
