Wopanga mtengo wabwino vae emulsion (vae) Cas: 24937-78-8

Kufotokozera kwaifupi:

Vae emulsion (Vae) amapezeka ndikusonkhanitsa ethylene ndi ethyl acetate malinga ndi kuchuluka kwina. Chidule cha Chingerezi cha Eva chikuyimira mawonekedwe a Ethylene, VA akuimira ma ecetate ethylene. Zomwe zili ndizogwirizana kwambiri. Malinga ndi zomwe zili mu VA zinthu zina zoumba komanso zosakaniza; Zomwe zimakhutira ndi 40% -90% yotchedwa mphira, zomwe zimagwiritsidwa ntchito makamaka ngati mphira, zingwe ndi zigawo za mafakitale. Zomwe zimachitika ndi zapamwamba kuposa 90%, zomwe zimatchedwa polyache acetate eyetalion mafuta odzola, ndipo imagwiritsidwa ntchito makamaka chifukwa cha zomata, zokutira, etc.

Ntchito za Vae

Onjezani guluu wophatikizika-1, chithovu / chithovu / madontho opita ku gulu lapadera, lomwe ndi la vanyl wapamwamba kwambiri ethylener othandizira mafuta odzola. Ili ndi mawonekedwe oyambira oyambira komanso kukhazikika kwamakina. Poyerekeza ndi mafuta odzola a Polyvinyl acetate, liwiro lake lokola, kutsatsa ndi katundu wina wogwiritsa ntchito akhoza kukhala bwino kwambiri. Imakhala ndi chotsatsa bwino pa filimu ya pulasitiki ndi ma aluminium zojambula, zofewa mpaka mapepala ozikidwa papepala, komanso mitundu yosiyanasiyana.

Ethylene-ethyl acetate wachikominisi ali ndi vuto lokana ndi kutsindika, zofewa, kukhazikika kwa ma raocomat, ndi mafinya, komanso mafilimu osokoneza bongo omwe ali ndi kuthekera. Eva ndi osiyana ndi zomwe zili pa pulasitiki, mankhwala, rabani, kuti atumizidwe, ndipo woyenera kuwumba, kuwombera pulasitiki, njira zina zokurira. Itha kugwiritsidwa ntchito ndi zingwe. Zingwe zokopa, chisamaliro chamankhwala, mafilimu, mapaipi, zinthu zomangira, zopangira zamagetsi, zowonjezera zamagetsi, zofunikira pa tsiku ndi zikhalidwe zosiyanasiyana.

Makhalidwe: Mafotokozedwe achidule a Vae ndikuyambitsa matenda a vinyl (VA) kukhazikitsidwa kwa polyethylene (pe), momwe VA ndi chinthu chachikulu chomwe chimakhudza momwe akugwirira ntchito, chifukwa VA ndi gulu la polar. Ndi kuwonjezeka kwa VA zomwe zili, makristallity amachepetsa, ndipo kusinthasintha, kukana kwamphamvu ndi kukana mafuta kumasintha. Komabe, pofika pofanana ndi polarity, kuyerekezera ndi mafilimu kumachuluka, ndipo moto woyatsidwa umawonjezeka pang'ono.
