VAE (Vinyl acetate)

Vinyl acetate (VAE), nke a maara nke ọma dị ka CH3COOCH = CH2, bụ monomer bụ isi eji emepụta polymers dị iche iche, karịsịa vinyl acetate-ethylene (VAE) copolymers. Nke a bụ nkọwa nke vinyl acetate na uru ọ pụtara:

1. Monomer na Polymer Mmepụta:

• Vinyl acetate bụ mmiri mmiri na-enweghị agba nke na-esi ísì ụtọ. Ọ bụ monomer isi eji eme ihe na njikọ nke polymers dị iche iche, gụnyere polyvinyl acetate (PVA), vinyl acetate-ethylene (VAE) copolymers, na vinyl acetate-vinyl versatate (VAV) copolymers.

2. Vinyl Acetate-Ethylene (VAE) Copolymers:

• A na-emepụta copolymer VAE site na copolymerizing vinyl acetate na ethylene n'ihu onye mbido polymerization na ihe mgbakwunye ndị ọzọ. Ndị copolymers ndị a na-egosipụta mgbanwe mgbanwe, adhesion, na mgbochi mmiri ma e jiri ya tụnyere polyvinyl acetate dị ọcha.

3. Ngwa:

• Ndị copolymer VAE na-ahụta ọtụtụ ihe na ụlọ ọrụ dị iche iche, gụnyere nrapado, mkpuchi, agba, ihe owuwu, akwa na mkpuchi akwụkwọ.
• N'ime ngwa nrapado, VAE copolymers na-enye ezigbo mmachi n'ọtụtụ ihe dị iche iche, na-eme ka ọ dị mma maka iji osisi, akwụkwọ mpempe akwụkwọ, na ihe nkwụnye nrụgide.
• Na mkpuchi na agba, VAE copolymers na-eje ozi dị ka ndị na-ekekọta ihe, na-enye ihe ndị na-emepụta ihe nkiri, ịdịte aka, na nkwụsị mmiri. A na-eji ha eme ihe n'ihe owuwu ụlọ, ihe eji achọ mma, na mkpuchi ụlọ ọrụ.
• N'ime ihe owuwu ihe, a na-eji VAE copolymers eme ihe dị ka ihe mgbakwunye na ngwa agha, ihe ntanye tile, grouts, na sealants iji meziwanye nrapado, mgbanwe, na nkwụsị mmiri.

4. Uru:

• Ndị copolymers VAE na-enye ọtụtụ uru karịa polymers ọdịnala, gụnyere obere nsi, ísì dị ala, ezigbo mmachi, mgbanwe, na mgbochi mmiri.
• Ha nwere enyi na gburugburu ebe obibi ma na-agbaso ụkpụrụ dị iche iche gbasara ogige organic na-agbanwe agbanwe (VOCs) na ihe ndị dị ize ndụ.

5. Mmepụta:

• A na-emepụta Vinyl acetate n'ụzọ bụ isi site na mmeghachi omume nke acetic acid na ethylene n'ihu ihe na-emepụta ihe, nke na-abụkarị palladium ma ọ bụ rhodium complex. Usoro a gụnyere ọtụtụ usoro, gụnyere carbonylation nke methanol iji mepụta acetic acid, sochiri esterification nke acetic acid na ethylene iji nye vinyl acetate.

Na nchịkọta, vinyl acetate (VAE) bụ monomer dị iche iche ejiri na-emepụta VAE copolymers, nke na-achọta ngwa ngwa dị ukwuu na nrapado, mkpuchi, agba, na ihe owuwu. Ngwongwo ya pụrụ iche na ọdịdị gburugburu ebe obibi na-eme ka ọ bụrụ ihe bara uru n'ụdị mmepụta ihe dị iche iche.
