VAE (Vinyl Acetate)

Vinyl acetate (VAE), ti a mọ ni kemikali bi CH3COOCH=CH2, jẹ monomer bọtini kan ti a lo ninu iṣelọpọ awọn oriṣiriṣi awọn polima, paapaa vinyl acetate-ethylene (VAE) copolymers.Eyi ni awotẹlẹ ti vinyl acetate ati pataki rẹ:

1. monomer ni iṣelọpọ polima:

• Vinyl acetate jẹ omi ti ko ni awọ pẹlu õrùn gbigbona.O jẹ monomer bọtini ti a lo ninu iṣelọpọ ti awọn oriṣiriṣi awọn polima, pẹlu polyvinyl acetate (PVA), vinyl acetate-ethylene (VAE) copolymers, ati vinyl acetate-vinyl versatate (VAV) copolymers.

2. Vinyl Acetate-Ethylene (VAE) Copolymers:

• VAE copolymers jẹ iṣelọpọ nipasẹ copolymerizing fainali acetate pẹlu ethylene ni iwaju olupilẹṣẹ polymerization ati awọn afikun miiran.Awọn copolymers wọnyi ṣe afihan irọrun ilọsiwaju, adhesion, ati resistance omi ni akawe si acetate polyvinyl mimọ.

3. Awọn ohun elo:

• Awọn copolymers VAE wa lilo lọpọlọpọ ni awọn ile-iṣẹ lọpọlọpọ, pẹlu awọn adhesives, awọn aṣọ, awọn kikun, awọn ohun elo ikole, awọn aṣọ, ati awọn aṣọ iwe.
• Ni awọn ohun elo adhesive, VAE copolymers pese ifaramọ ti o dara julọ si ọpọlọpọ awọn sobusitireti, ṣiṣe wọn dara fun lilo ninu awọn adhesives igi, awọn adhesives iwe, ati awọn adhesives ti o ni agbara titẹ.
• Ni awọn aṣọ ati awọn kikun, awọn copolymers VAE ṣiṣẹ bi awọn alasopọ, pese awọn ohun-ini iṣelọpọ fiimu, agbara, ati idena omi.Wọn ti wa ni lilo ni ti ayaworan aso, awọn kikun ti ohun ọṣọ, ati ise.
• Ninu awọn ohun elo ikole, VAE copolymers ni a lo bi awọn afikun ninu awọn amọ-lile, awọn adhesives tile, grouts, ati sealants lati mu ilọsiwaju pọsi, irọrun, ati idena omi.

4. Awọn anfani:

• VAE copolymers nfunni ni ọpọlọpọ awọn anfani lori awọn polima ibile, pẹlu majele kekere, oorun kekere, ifaramọ ti o dara, irọrun, ati idena omi.
• Wọn jẹ ọrẹ ayika ati ni ibamu pẹlu awọn ilana pupọ nipa awọn agbo ogun Organic iyipada (VOCs) ati awọn nkan eewu.

5. iṣelọpọ:

• Vinyl acetate jẹ iṣelọpọ nipataki nipasẹ iṣesi ti acetic acid pẹlu ethylene ni iwaju ayase kan, ni deede palladium tabi eka rhodium.Ilana naa pẹlu awọn igbesẹ pupọ, pẹlu carbonylation ti kẹmika lati ṣe agbejade acetic acid, atẹle nipa esterification ti acetic acid pẹlu ethylene lati mu acetate fainali jade.

Ni akojọpọ, vinyl acetate (VAE) jẹ monomer to wapọ ti a lo ninu iṣelọpọ awọn copolymers VAE, eyiti o rii awọn ohun elo lọpọlọpọ ni awọn adhesives, awọn aṣọ, awọn kikun, ati awọn ohun elo ikole.Awọn ohun-ini alailẹgbẹ rẹ ati iseda ore ayika jẹ ki o jẹ paati ti o niyelori ni ọpọlọpọ awọn agbekalẹ ile-iṣẹ.
