Ko te Vinyl acetate (VAC) he matū matū tino nui me te tauira ngota o C4H6O2, e mohiotia ana ko te vinyl acetate me te vinyl acetate.Vinyl acetate te nuinga whakamahia i roto i te hanga o te waipiro polyvinyl, ethylene-vinyl acetate copolymer (EVA resin), ethylene-vinyl alcohol copolymer (EVOH resin), vinyl acetate-vinyl chloride copolymer (vinyl chloride resin), latex ma, kiriaku muka me etahi atu hua.Kei te whakamahia nuitia i roto i nga mara o te muka waihanga, te paninga, te slurry, te kiriata, te tukatuka hiako, te whakapai ake i te oneone, me te whai whakaaro nui ki te whakawhanaketanga me te whakamahinga.Ko nga huarahi tukanga o te vinyl acetate ko te tikanga carbide acetylene, te tikanga acetylene hau maori me te tikanga hinu ethylene.Ko te tikanga carbide acetylene te nuinga e whakamahia ana i Haina, a ko te kaha o te hanga o te tikanga carbide acetylene ka eke ki te 62% i te 2020.
I nga tau tata nei, ko te hiahia o te maakete o te vinyl acetate i Haina kua piki ake te ahua o te piki haere.E ai ki nga tatauranga a China Chemical Fiber Industry Association, i te tau 2016, ko te kohi o te vinyl acetate i Haina ko te 1.94 miriona taranata, i piki ki te 2.33 miriona taranata i te tau 2019. I pangia e te COVID-19 i te haurua tuatahi o te 2020, te he iti te reeti whakahaere o nga ahumahi o raro, na te iti o te hekenga o te kai o te vinyl acetate ki te 2.16 miriona taranata;Na te whakapumautanga o te ahuatanga o te mate urutaru i te haurua tuarua o te tau me te tere o te whakaora i nga mahi ohaoha, ka tere te hoki mai o te tono mo te acetate vinyl mai i te haurua tuarua o te 2020 ki te haurua tuatahi o te 2021, kua piki te utu o te maakete, me te kua ora ake te ahumahi.
Ko te hanganga tono o te vinyl acetate i Haina he tino pumau, me te waipiro polyvinyl, te polyvinyl acetate, te waiu VAE me te resin EVA hei hua matua.I te 2020, ko te wahanga o te waipiro polyvinyl i roto i te hanganga kai o te whare o te vinyl acetate ka tae ki te 65%, a ko te waahanga katoa o te polyvinyl acetate, te wai wai VAE me te kapia EAV ka 31%.
I tenei wa, ko Haina te kaha nui o te vinyl acetate i te ao.I te 2020, ko te kaha o Haina mo te vinyl acetate ka eke ki te 2.65 miriona taranata, mo te 40% o te kaha katoa o te ao.I nga tau tata nei, kua heke haere te kaha whakamuri o te umanga vinyl acetate o Haina, a kua taapirihia te kaha ki te whakakii i te waahi o te maakete.Na te arotautanga tonu o te hanganga tuku ahumahi, kua whakaatuhia e te hanga vinyl acetate a Haina te ahua o te tipu.E ai ki nga tatauranga a te China Chemical Fiber Industry Association, kua piki ake te hanga vinyl acetate mai i te 1.91 miriona taranata i te tau 2016 ki te 2.28 miriona taranata i te tau 2019, me te pikinga o te tipu a-tau o te 5.98%;I te tau 2020, na te iti o te utu hinu hinu o te ao, kua heke te utu whakaputanga o nga tikanga hinu ethylene ki tawahi, kua piki te kawemai o te vinyl acetate ki Haina, a kua heke te hanga whare o te vinyl acetate ki te 1.99 miriona taranata;Mai i te haurua tuarua o 2020, me te whakaoranga ohaoha o te ao me te pikinga o nga utu hinu o te ao, kua mahana ake te hanga o te umanga acetate vinyl a-whare.
