ʻO Vinyl Acetate Monomer (VAM) kahi mea koʻikoʻi no ka hana ʻana i nā intermediates, resins, a me emulsion polymers, i hoʻohana ʻia i nā uea, nā uhi, nā adhesives, a me nā pena.
ʻO nā kumu nui e pili ana i ka ulu ʻana o ka mākeke Vinyl Acetate o ka honua ke ulu nei ka noi mai ka ʻai meaʻai a me nā ʻoihana Solar.Eia nō naʻe, ʻo ka hiki ʻole i nā kumukūʻai feedstock o Vinyl Acetate ke manaʻo ʻia e pale i ka ulu ʻana o ka mākeke.
I ka ʻōlelo o ka māhele mākeke, ʻo ka ʻāina ʻo Asia Pākīpika e lilo i mākeke wikiwiki loa, no ka piʻi ʻana o ka hoʻonui ʻana i ke kūkulu ʻana a me ka ʻoihana kaʻa i nā ʻāina e like me Kina (ʻO ia ka mea hana nui loa i ka ʻoihana a me nā pena a me nā ʻoihana uhi) .Eia kekahi, ʻo Kina ka mea kūʻai nui loa a me ka mea hana o nā adhesives a me nā sealants e pono ai ka VMA.
Manaʻo ka ʻāpana ethylene-vinyl alcohol (EVOH) e loaʻa ka kiʻekiʻe kiʻekiʻe o ka ulu ʻana ma luna o ka wā wānana i ka māhele Application ma muli o ka piʻi nui ʻana o ka noi i ka ʻoihana pale, ka hana polymer, a me nā noi bottling plastic.
Hoʻohui ʻia ka mākeke Vinyl Acetate honua.ʻO nā mea pāʻani nui i ka mākeke Vinyl Acetate honua ʻo Dow Chemical Company, Celanese Corporation (Hoechst Celanese), China Petrochemical Corporation, Chang Chun Group, LyondellBasell, a me nā mea ʻē aʻe.
Ma ʻApelila 1, 2020, ua hoʻolaha ʻo Celanese Corporation (kahi hui kemika a me nā ʻoihana kūikawā) ua hoʻopau ʻo ia i ka loaʻa ʻana o ka ʻoihana ʻo Nouryon polymer powders i hāʻawi ʻia ma lalo o ka brand Elotex.E hoʻohui ʻo Celanese i ka waihona huahana Elotex a me nā mea hana i loko o kāna ʻoihana emulsion vinyl acetate-ethylene (VAE) honua e hoʻokō hou i ka noi huahana honua.
He aha ke ʻano o ka mākeke ma ka mākeke monomer vinyl acetate honua?
Ma Asia-Pacific, ʻo Ethylene Acetoxylation ka hana hana nui i hoʻohana ʻia no ka hana Vinyl Acetate Monomer.Ua ukali ia e ka Acetylene/Acetic Acid Addition.ʻO nā mea kanu nui e hoʻohana ana i ka Ethylene Acetoxylation ʻo CCD Singapore Jurong Island Vinyl Acetate Monomer (VAM) Plant, Dairen Chemical Corporation Mailiao Vinyl Acetate Monomer (VAM) Plant 2, a me Celanese Corporation Nanjing Vinyl Acetate Monomer (VAM) Plant.ʻO nā mea kanu nui e hoʻohana ana i ka Acetylene / Acetic Acid Addition ʻo Sinopec Great Wall Energy Chemical Vinyl Acetate Monomer (VAM) Plant, Sinopec Chongqing SVW Chemical Co., Ltd Vinyl Acetate Monomer (VAM) Plant.
