Vinyl acetate (VAM)

Nkọwa:Vinyl acetate (VAC), makwaara dị ka vinyl acetate, bụ ihe dị mkpa kemịkalụ akụrụngwa.Site na polymerization onwe ma ọ bụ copolymerization na monomers ndị ọzọ, vinyl acetate nwere ike ịmepụta ngwaahịa dị ka polyvinyl alcohol (PVA), vinyl acetate ethylene copolymer (EVA), polyvinyl acetate (PVAc), vinyl acetate vinyl chloride copolymer (EVC), na ndị ọzọ.Ngwaahịa ndị a nwere ọtụtụ ihe eji eme ihe, nke a na-ejikarị eme ihe na nrapado, akwụkwọ ma ọ bụ akwa ákwà, agba, inks, nhazi akpụkpọ anụ, emulsifiers, ihe nkiri mmiri na-agbaze, ndị na-emezi ala na ihe ndị ọzọ.

Njirimara:Na-arụ ọrụ na ọkụ

Ngwa:

1. Vinyl acetate bụ isi akụrụngwa maka imepụta eriri vinyl sịntetik.

2. Vinyl acetate bụ polymerized n'onwe ya ma ọ bụ copolymerized na sub-monomers iji nweta mmanya polyvinyl, EVA, EVC, vinyl acetate-acrylonitrile fibers, vinyl acetate-acrylate copolymers, ihe niile nwere mkpa ụlọ ọrụ na-eji na-eji ọtụtụ ebe.A na-eji ya dị ka ihe nkedo, ihe mkpuchi ihe owuwu ihe eji eme ihe, ihe na-edozi akwa na ihe na-emecha, ihe na-eme ka akwụkwọ sie ike, na maka ịmepụta iko nchekwa, wdg.

3. Vinyl acetate na-emeghachi omume na ethanol na bromine iji nweta etiti nke ọgwụ Methionazole - bromoacetaldehyde diethyl acetal.

4. A na-eji resin fiber synthesis, na-ejikwa dị ka intermediate na ihe nkedo mmanụ wụsa ebe depressant na thickener.

Ndụmọdụ n'ozuzu:Mgbe a na-ekpo ọkụ ma ọ bụ n'okpuru ọrụ nke eriri anya ma ọ bụ peroxides, ihe ahụ na-emekarị ka ọ bụrụ polymerization, na-ebute ọkụ na mgbawa ihe ize ndụ.Ọ na-emeghachi omume ike na oxidants siri ike
