Wopanga Mtengo Wabwino VAE EMULSION(VAE) CAS:24937-78-8

Kufotokozera mwachidule:

VAE EMULSION(VAE) imapezeka posonkhanitsa ethylene ndi ethyl acetate molingana ndi magawo osiyanasiyana.Chidule cha Chingerezi cha EVA chikuyimira ethylene, VA imayimira zigawo za acetate ethylene.Zomwe zilimo zikugwirizana kwambiri.Malinga ndi zomwe zili mu VA, VAE EMULSION(VAE) ikhoza kugawidwa m'magulu atatu: zomwe zili mu VA ndi 5%Chemicalbook-40% yotchedwa EVA pulasitiki, yomwe imagwiritsidwa ntchito kwambiri posintha polyethylene, mawaya opanga mawaya ndi zingwe, makanema owonda, ndi zinthu zina akamaumba ndi osakaniza;Zomwe zili mu VA ndi 40% -90% yotchedwa mphira wa EVA, yomwe imagwiritsidwa ntchito makamaka ngati mphira, zingwe ndi zida zamagalimoto zamagalimoto.VA zili pamwamba kuposa 90%, amene amatchedwa polyache acetate emulsion lotion, ndipo makamaka ntchito zomatira, zokutira, etc.

Ntchito za VAE

Onjezani guluu pawiri-1, thovu / masanjidwe pawiri kwa guluu wapadera, amene ndi apamwamba vinilu acetate ethylene copolymer odzola.Ili ndi mamasukidwe abwino kwambiri oyambira komanso kukhazikika kwamakina.Poyerekeza ndi mafuta odzola a polyvinyl acetate, liwiro lake lochiritsa, zomatira ndi zina zogwiritsira ntchito zitha kusintha kwambiri.Ili ndi kumamatira kwabwino kwa filimu yapulasitiki ndi zojambulazo za aluminiyamu, kufewa kosatha kumagulu opangidwa ndi mapepala, ndi mitundu yosiyanasiyana.

Chikominisi cha ethylene-ethyl acetate chimakhala ndi kukana kwabwino komanso kusweka kwa kupsinjika, kufewa, kutsika kwambiri, kukana kuphulika ndi kukhazikika kwamankhwala, magwiridwe antchito abwino amagetsi, kuyanjana kwabwino, kachulukidwe kakang'ono, ndi zodzaza, zotchingira moto Wothandizira amakhala wogwirizana bwino.EVA ndi yosiyana ndi zomwe zili VA, ChemicalBook kuchokera ku pulasitiki, mphira, mpaka emulsion, ndipo mawonekedwe ogwiritsira ntchito ndi otakata, oyenera kufinya, jekeseni akamaumba, kuwomba pulasitiki, ❖ kuyanika, kutentha akamaumba ndi njira zina processing.Itha kugwiritsidwa ntchito pazingwe.Zigawo zosindikizira, chithandizo chamankhwala, filimu yotetezera, mapaipi, zipangizo zamapepala, zipangizo zomangira, zipangizo zamagetsi, zipangizo zamagalimoto ndi zofunikira za tsiku ndi tsiku.

Makhalidwe: Kufotokozera mwachidule kwa VAE ndikuyambitsa gulu la vinyl acetate (VA) mumtundu wautali wa polyethylene (PE), momwe VA yokhutira ndi chinthu chachikulu chomwe chimakhudza ntchito yake, chifukwa VA ndi gulu la polar.Ndi kuchuluka kwa zomwe zili mu VA, crystallinity imachepa, ndipo kusinthasintha, kukana kwamphamvu ndi kukana kwamafuta kumakhala bwino.Komabe, ndi kuwonjezereka kofanana kwa polarity yake, kuyanjana ndi zodzaza kumawonjezeka, ndipo kuchedwa kwamoto kumawonjezekanso pang'ono.
