VAE (Vinyl Acetate)

Vinyl acetate (VAE), imiti izwi nka CH3COOCH = CH2, ni monomer nyamukuru ikoreshwa mugukora polymers zitandukanye, cyane cyane vinyl acetate-Ethylene (VAE) kopolymers.Dore incamake ya vinyl acetate n'akamaro kayo:

1. Monomer mu musaruro wa Polymer:

• Vinyl acetate ni amazi atagira ibara afite impumuro nziza.Ni monomer yingenzi ikoreshwa muguhuza polymers zitandukanye, harimo polyvinyl acetate (PVA), vinyl acetate-ethylene (VAE) copolymers, na vinyl acetate-vinyl verisiyo (VAV).

2. Vinyl Acetate-Ethylene (VAE) Copolymers:

• VAE copolymers ikorwa na copolymerizing vinyl acetate hamwe na Ethylene imbere yabatangije polymerisation nibindi byongeweho.Izi kopi yerekana uburyo bworoshye bwo guhinduka, gufatira hamwe no kurwanya amazi ugereranije na acetate nziza ya polyvinyl.

3. Gusaba:

• VAE copolymers isanga ikoreshwa cyane mubikorwa bitandukanye, birimo ibifatika, ibipapuro, amarangi, ibikoresho byubwubatsi, imyenda, hamwe nimpapuro.
• Mubikoresho bifata, VAE copolymers itanga neza cyane kumurongo mugari wa substrate, bigatuma ikoreshwa muburyo bwo gukoresha ibiti, ibipapuro, hamwe nudukoko twinshi.
• Mu gusiga amarangi, kopi ya VAE ikora nka binders, itanga ibintu byerekana firime, biramba, kandi birwanya amazi.Zikoreshwa muburyo bwububiko, amarangi ashushanya, hamwe ninganda.
• Mu bikoresho byubwubatsi, kopi ya VAE ikoreshwa nkinyongera muri minisiteri, kumatafari ya tile, grout, hamwe na kashe kugirango tunonosore, guhuza, no kurwanya amazi.

4. Ibyiza:

• VAE copolymers itanga ibyiza byinshi kurenza polymers gakondo, harimo uburozi buke, umunuko muke, gufatana neza, guhinduka, no kurwanya amazi.
• Bangiza ibidukikije kandi bubahiriza amabwiriza atandukanye yerekeye ibinyabuzima bihindagurika (VOC) nibintu byangiza.

5. Umusaruro:

• Vinyl acetate ikorwa cyane cyane nigisubizo cya acide acetike hamwe na Ethylene imbere ya catalizator, mubisanzwe palladium cyangwa rhodium.Inzira ikubiyemo intambwe nyinshi, zirimo karbonelation ya methanol kugirango itange aside irike, hanyuma hakurikiraho esterifike ya acide acetike hamwe na Ethylene kugirango itange vinyl acetate.

Muncamake, vinyl acetate (VAE) ni monomer itandukanye ikoreshwa mugukora kopi ya VAE, isanga ibintu byinshi mubifata, ibifuniko, amarangi, nibikoresho byubwubatsi.Imiterere yihariye hamwe nibidukikije byangiza ibidukikije bituma iba ikintu cyingirakamaro mubikorwa bitandukanye byinganda.
