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

kufotokozera mwachidule:

VAE EMULSION (VAE) imapezeka posonkhanitsa ethylene ndi ethyl acetate molingana ndi kuchuluka kosiyana. Chidule cha Chingerezi cha EVA chikuyimira kapangidwe ka ethylene, VA ikuyimira zigawo za ethylene za acetate. Zomwe zili mkati mwake zimagwirizana kwambiri. Malinga ndi kuchuluka kosiyana kwa VA, VAE EMULSION (VAE) ikhoza kugawidwa m'magulu atatu: kuchuluka kwa VA ndi 5% Chemicalbook-40% yotchedwa EVA pulasitiki, yomwe imagwiritsidwa ntchito kwambiri posintha polyethylene, kupanga mawaya ndi zingwe, mafilimu opyapyala, ndi zinthu zina zomangira ndi kusakaniza; kuchuluka kwa VA ndi 40%-90% yotchedwa EVA rabara, yomwe imagwiritsidwa ntchito kwambiri pa rabara, zingwe ndi zigawo zamafakitale zamagalimoto. Kuchuluka kwa VA kuli kopitilira 90%, komwe kumatchedwa polyache acetate emulsion lotion, ndipo kumagwiritsidwa ntchito kwambiri pa zomatira, zokutira, ndi zina zotero.

Kugwiritsa ntchito kwa VAE

Onjezani guluu wa compound-1, thovu/mawonekedwe ake ku guluu wapadera, womwe ndi lotion yapamwamba kwambiri ya vinyl acetate ethylene copolymer. Ili ndi kukhuthala koyambirira kwabwino komanso kukhazikika kwa makina. Poyerekeza ndi lotion ya polyvinyl acetate, liwiro lake lotha kuuma, kumamatira kwake ndi zinthu zina zomwe zimagwiritsidwa ntchito zimatha kukonzedwa bwino. Ili ndi kumamatira bwino ku filimu yapulasitiki ndi zojambulazo za aluminiyamu, kufewa kosatha ku zinthu zopangidwa ndi mapepala, komanso mitundu yosiyanasiyana ya ma formula.

Ethylene-ethyl acetate communist ili ndi mphamvu yabwino yolimbana ndi kupsinjika, kufewa, kusinthasintha kwakukulu, kukana kubowola ndi kukhazikika kwa mankhwala, magwiridwe antchito abwino amagetsi, kuyanjana bwino kwa biochemical, kuchepa kwa kachulukidwe, ndi zodzaza, choletsa moto. Chothandizirachi chimagwirizana bwino. EVA ndi yosiyana ndi zomwe zili mu VA, ChemicalBook kuyambira pulasitiki, rabara, mpaka emulsion, ndipo mitundu yogwiritsira ntchito ndi yayikulu, yoyenera kufinya, kuumba jakisoni, pulasitiki yopukutira, zokutira, kuumba kutentha ndi njira zina zokonzera. Itha kugwiritsidwa ntchito pa zingwe. Zigawo zotsekera, chisamaliro chamankhwala, filimu yoteteza kutentha, mapaipi, zipangizo za mbale, zipangizo zomangira, zowonjezera zamagetsi, zowonjezera zamagalimoto ndi zofunikira za tsiku ndi tsiku.

Fomula Yopangira Kapangidwe ka Maselo:

Makhalidwe: Kufotokozera mwachidule kwa VAE ndikuyika gulu la vinyl acetate (VA) mu kapangidwe ka unyolo wautali wa polyethylene (PE), momwe kuchuluka kwa VA ndiko chinthu chachikulu chomwe chimakhudza magwiridwe antchito ake, chifukwa VA ndi gulu la polar. Ndi kuwonjezeka kwa kuchuluka kwa VA, crystallinity imachepa, ndipo kusinthasintha, kukana kukhudzidwa ndi kukana mafuta kumawonjezeka. Komabe, ndi kuwonjezeka kofanana kwa polarity yake, kugwirizana ndi zodzaza kumawonjezeka, ndipo kuchedwa kwa moto kumawonjezekanso pang'ono.
