I-vinyl ye-vinyl
I-Vinyl Acetate (god) sisixhobo esibalulekileyo semichiza esiyi-molecular ngefomula yemolekyuli ye-C4H6H6O, ekwabizwa ngokuba yi-vinyl acetate kunye ne-vinyl acetate. I-Vinyl Acetate isetyenziswa ikakhulu ekuvelisweni kwe-polyvinyl utywala, i-E-Ethylene-vinyl), i-Evaroly-vinyl Cylide-vinyl i-vinyl copolymer. Isetyenziswe ngokubanzi kwi-fiber yefayibha ye-fiber, i-caider, i-slirry, ifilimu, ukulungisa kwesikhumba, ukuphuculwa komhlaba, nokusetyenziswa. Inkqubo yenkqubo yeVinyl Acetate ibandakanya indlela ye-carbide ye-acetylene, indlela ye-Acetylene yeNdalo ye-Acetylene kunye nendlela ye-petrolene. Indlela ye-carbide acetylene isetyenziswa ikakhulu eTshayina, kunye nemveliso yokuvelisa ye-Acetylene ye-Acetylene iya kufikelela kwi-62% ngo-2020.
Kwiminyaka yakutshanje, imfuno yentengiso ye-vinyl acetate eTshayina ibonakalise imeko ephezulu kakhulu. Ngokweenkcukacha-manani zoMbutho weShedyuli yeFimikhezi yeFizikhali yeFimikhezi yeFimikhezi yeFizikhali, ngo-2016, i-vinyl engu-vinyl i-chinare yayiyi-1.94 yezigidi zeetoni eziphantsi kwe-18,33. Ngokuzinza kwemeko yesifo kwisiqingatha sesibini sonyaka kunye nokubuyiselwa ngokukhawuleza kwemveliso yezoqoqosho, imfuno yeVinyl i-vinyl ibuyise ngokukhawuleza ukusuka kwisiqingatha sesibini se-2021, ixabiso lentengiso livele kakhulu, kwaye ishishini lihlaziywa.
Isakhiwo sebango seVinyl Acetate e-China sizinzile, kunye notywala bePolyvinyl, i-polyvinyl acetate, i-vae lotion kunye ne-eva relin njengeemveliso eziphambili. Ngo-2020, umda wee-polyvinyl utywala kwindawo yokusebenzisa yasekhaya ye-vinyl acetate iya kufikelela kuma-65%, kwaye iyonke i-polyvinyl acetate, i-vae lot kunye ne-EAV i-EAV iya kuba ngama-31%.
Okwangoku, i-China inamandla amakhulu e-vinyl ye-vinyl yehlabathi. Ngo-2020, amandla e-Chinyl Acetate aya kufikelela kwiitoni ezingama-2.65 ezigidi, i-accounting malunga ne-40% yomthamo opheleleyo wehlabathi. Kwiminyaka yakutshanje, umthamo ongasemva kwi-vinya ye-vinyl ye-vinyl irhoxisiwe ngokuthe ngcembe, kwaye i-Advance yongezwa ukugcwalisa i-Gap. Ngokuphumelela okuqhubekayo kwendlela yokubonelela ngeshishini, i-china ye-vinyl ye-vinyl ye-vinyl ye-vinyl ibonakalise imeko yokukhula iyonke. Ngokwamanani angabalandeli boMbutho weShishini lase Chica Clic, i-vinyl ye-vinyl ye-vinyl ye-vinyl inyuke ukusuka kwi-1.91 yezigidi ngo-2016 ukuya kwi-2.21 yezigidi ukuya kwi-2.28 yezigidi ngonyaka we-5.98; Ngo-2020, ngenxa yexabiso leoyile elisezantsi le-oyile, iindleko zemveliso ze-Petrolene ye-Petrolene yancitshiswa, ukungenisa kweVinyl Acetate e-Chinya, kunye nemveliso yasekhaya ye-vinyl inciphile ukuya kwi-1.99 yezigidi zeetoni; Ukususela kwisiqingatha sesibini sama-2020, ngokuvuselelwa koqoqosho lwehlabathi kunye nokunyuka kwamaxabiso e-oyile jikelele, ukuveliswa kweshishini le-vinyl ye-vinyl ye-vinyl ye-vinyl ifudumeza.
