I-Vinyl Acetate (VAF) iyinto ebalulekile ye-Organic Chemical Ream ebalulekile ngefomula ye-molecular ye-C4H6O2, eyaziwa nangokuthi i-Vinyl Acetate kanye ne-Vinyl Acetate. Vinyl acetate is mainly used in the production of polyvinyl alcohol, ethylene-vinyl acetate copolymer (EVA resin), ethylene-vinyl alcohol copolymer (EVOH resin), vinyl acetate-vinyl chloride copolymer (vinyl chloride resin), white latex, acrylic fiber and other products. Isetshenziswa kabanzi emikhakheni ye-fiber yokwenziwa, ukunamathela, ukubhoga, ifilimu, ukucubungula kwesikhumba, ukuthuthukiswa kwenhlabathi, futhi kunethemba elibanzi lokuthuthuka nokusetshenziswa. Imizila yenqubo ye-vinyl acetate ifaka indlela ye-carbide acetylene, indlela yemvelo ye-acetylene nendlela ye-petroleum ethylene. Indlela ye-carbide acetylene isetshenziswa ikakhulukazi eChina, futhi umthamo wokukhiqiza we-Carbide acetylene indlela uzofinyelela kuma-62% ngo-2020.
Eminyakeni yamuva nje, ukufunwa kwemakethe ye-vinyl acetate eChina kukhombisile ukuthambekela okuphezulu. Ngokusho kwezibalo zeChina Chemical Fiber Imboni Enhlangano Inhlangano, ngonyaka we-2016, ukusetshenziswa okubonakalayo kweVinyl acetate eChina kwakungamathani ayizigidi ezingama-120, okuholela ekunciphiseni amathani angama-120. With the stabilization of the epidemic situation in the second half of the year and the rapid recovery of economic production, the demand for vinyl acetate recovered rapidly from the second half of 2020 to the first half of 2021, the market price rose significantly, and the industry recovered.
Ukwakheka kwesicelo seVinyl Acetate eChina kuyazinza kakhulu, nge-polyvinyl alcohol, polyvinyl acetate, vayvinyl acetate, vaevinyl andva resin njengemikhiqizo esemqoka. Ngo-2020, ingxenye ye-polyvinyl alcohol ekwakhekeni kokusetshenziswa kwasekhaya kwe-viny acetate izofinyelela kuma-65%, kanye nenani eliphelele le-polyvinyl acetate, i-vae lootion kanye ne-Resen Resin izoba ngo-31%.
Njengamanje, iChina inamandla amakhulu kaVinyl acetate emhlabeni. Ngo-2020, umthamo we-vinyl acetate uzofinyelela amathani ayizigidi ezingama-2.65, azobalwa cishe ama-40% omhlaba wonke emhlabeni. Eminyakeni yamuva nje, umthamo wangemuva embonini ye-acetate ye-vinyl yaseChina kancane kancane uhoxisile kancane kancane, futhi kwanezelwa amandla athuthukile ukugcwalisa igebe lemakethe. Ngokusebenzisa kahle kwesakhiwo esihlinzeka ngemboni, ukukhiqizwa kwe-vinyl acetate ye-vinyl kubonise umkhuba wokukhula jikelele. Ngokusho kwezibalo ze-China Chemical Fiber Imboni Inhlangano, ukukhiqizwa kwe-vinyl acetate yasekhaya kukhuphuke kusuka kumathani ayizigidi eziyi-1,91 ngonyaka we-2016 kuya ku-2.28 million amathani ngonyaka we-5.98% ka-2019; Ngo-2020, ngenxa yentengo kawoyela ephansi yamazwe omhlaba, izindleko zokukhiqiza ze-ethylene ye-ethylene ye-petroleum phesheya kwezilwandle zancishiswa, ukungenisa kwe-vinyl acetate eChina kwanda, futhi ukukhiqizwa kwasekhaya kwe-vinyl acetate kwehlise amathani ayi-1,99; Kusukela ngengxenye yesibili ka-2020, ngokuvuselelwa komnotho womhlaba kanye nokunyuka kwamanani kawoyela omhlaba wonke, ukukhiqizwa kwemboni yasekhaya yaseVinyl Acetate sekufudumele.
