Uruganda Igiciro Cyiza VAE EMULSION (VAE) CAS: 24937-78-8

ibisobanuro bigufi:

VAE EMULSION (VAE) iboneka mugukusanya Ethylene na Ethyl acetate ukurikije ibipimo bitandukanye. Amagambo ahinnye ya EVA yicyongereza agereranya Ethylene, VA igereranya ibice bya acetate. Ibirimo bifitanye isano ya hafi. Ukurikije ibikubiye muri VA bitandukanye, VAE EMULSION (VAE) irashobora kugabanywamo ibyiciro bitatu: ibirimo VA ni 5% ya Chemical Book-40% bita EVA plastike, ikoreshwa cyane cyane muguhindura polyethylene, gukora insinga ninsinga, firime zoroshye, nibindi bicuruzwa bibumba no kuvanga; Ibirimo VA ni 40% -90% bita EVA reberi, ikoreshwa cyane cyane muri reberi, insinga nibikoresho byinganda. Ibirimo VA biri hejuru ya 90%, aribyo bita amavuta yo kwisiga ya polyache acetate, kandi akoreshwa cyane cyane kubifata, gutwikira, nibindi.

Porogaramu ya VAE

Ongeramo ifumbire mvaruganda-1 compound ifuro / imiterere ivanze na kole idasanzwe, ikaba ari vinyl acetate yo mu rwego rwohejuru ya lisansi ya kopolymer. Ifite ubwiza bwambere bwambere kandi butekanye. Ugereranije na lisansi ya polyvinyl acetate, umuvuduko wacyo wo gukiza, gufatira hamwe nibindi bikoresho birashobora kunozwa cyane. Ifite neza kuri firime ya plastike na aluminiyumu, ubworoherane buhoraho kumpapuro zishingiye ku mpapuro, hamwe nuburyo butandukanye.

Ethylene-Ethyl acetate ya gikomunisiti ifite ingaruka nziza zo kurwanya no guhagarika umutima, ubworoherane, elastique nyinshi, anti-puncture na chimique, imikorere myiza yamashanyarazi, biocompatibilité nziza, ubucucike buke, hamwe nuwuzuza, flame retardant Umukozi afite ubwuzuzanye bwiza. EVA itandukanye nibiri muri VA, Igitabo cya Chemical kuva muri plastiki, reberi, kugeza kuri emulsiyo, kandi urwego rusaba ni rugari, rukwiriye gukanda, kubumba inshinge, guhuha plastike, gutwikira, kubumba ubushyuhe nubundi buryo bwo gutunganya. Irashobora gukoreshwa kumugozi. Gufunga ibice, ubuvuzi, gukingura firime, imiyoboro, ibikoresho byisahani, ibikoresho byubaka, ibikoresho byamashanyarazi, ibikoresho byimodoka nibikenerwa buri munsi.

Imiterere ya molekulari:

Ibiranga: Ibisobanuro bigufi bya VAE ni ukumenyekanisha itsinda rya vinyl acetate (VA) mumurongo muremure wa polyethylene (PE), aho ibikubiye muri VA aribintu bikomeye bigira ingaruka kumikorere, kuko VA nitsinda rya polar. Hamwe no kwiyongera kwa VA, kristu iragabanuka, kandi guhinduka, kurwanya ingaruka no kurwanya amavuta biratera imbere. Ariko, hamwe no kwiyongera gukwiranye na polarite yayo, guhuza hamwe nuwuzuza byiyongera, kandi gucana umuriro nabyo byiyongereyeho gato.
