Eva Sera (otentha Sungunulani zomatira) ali osiyanasiyana applicability, monga PA (polypropylene),

Pe (polyethylene) ndi zinthu zina zopanda polar, komanso zimatha kukhala ndi mgwirizano wabwino.

Mzere womata uli wabwino kutsika kutentha kukana, kukana kwamadzi ndi chinyezi

kukana.

Chifukwa sera ya EVA (yotentha yosungunuka) imakhala yolimba, imakhala yofewa pang'ono kuposa

poliyesitala ndi polyamide otentha amasungunuka zomatira, ndi mfundo zake softening lonse ndi za 100 ° C, kotero

ntchito zake ndizochepa.

Eva Wax (zomatira zotentha) amapangidwa ndi utomoni wa Eva, wolimbitsa utomoni, sera ndi okhazikika.

Utomoni wa Eva udakhazikitsa maunyolo amfupi okhala ndi ma polar acetic acid majini kulowa

maunyolo okhala ndi ethylene, omwe amasokoneza mawonekedwe amiyala yapachiyambi, amapangitsa EVA kukhala nayo

"Kuchita pulasitiki", ndikuchepetsa kuchepa kwa ethylene m'matangadza a nthambi,

kuonjezera mtunda pakati pa maunyolo polima, kupanga utomoni EVA kusinthasintha ndi

zotanuka.

Zomwe zili mu VA mu utomoni wa Eva zitha kukhala zotsika mpaka zochepa. Chifukwa chake,

kuchuluka kwa VA ndi MI (kusungunuka kwa index, kuwonetsa kulemera kwake kwa maselo) mu utomoni ndi

zinthu zofunika kwambiri zomwe zimatsimikizira mwachindunji ndikukopa mawonekedwe a Eva.

Nthawi zambiri, zomwe zili ndi Eva ndizokwera, mphamvu zomatira zimawonjezeka, kunyoweka kwa zomatira

zakuthupi ndi zabwino, kuchiritsa nthawi ikuchedwa, kutentha kwa kutentha kumatsika. Mndandanda wosungunuka ndi wapamwamba,

kutanthauza kutsika kwa maselo ochepa, mamasukidwe akayendedwe otsika, kunyowa bwino, kutentha kwambiri,

kumamatira kosalekeza.

Mumakina opangidwa ndi ethylene, Eva ali ndi mphamvu zolimba kuposa EEA (ethylene-Ethyl

acrylate), EAA (ethylene-propylene ester) ndi EMA (ethylene-propylene ester), ndipo

zimasiyanasiyana ndi zomwe zili mu VA.Ngati Mi ya EVA ndiyosiyana, kusintha kwa kusakhazikika

mphamvu ndi zambiri.

Mphamvu yolimba ya sera ya EVA imachepa ndikuwonjezeka kwa zinthu za VA, ndikukhala

zochepa kwambiri pamene VA zili zoposa 25%.

Kukhazikika kosasintha kwa EVA ndikofanana ndi PVC yofewa. Imachepa ndikukula kwa

VA, Ndi kuwonjezeka kwa MI, kukhazikika kolimba kumachepa.

Utomoni wa Eva umagwirizana, utha kusakanikirana ndi mitundu ina ya utomoni kuti musinthe

thupi katundu. Ngati utomoni wa Eva ndi nitrocellulose zasakanikirana, nitrocellulose ili ndi f

lexibility, mikangano kukana ndi kutentha kusindikiza.

Okhwima PVC wothira 5% ~ 10% EVA ZINAWATHERA bwino fluidity ndi bwino zimakhudza

kukana. Eva ophatikizidwa ndi utomoni wa Polyamide ali ndi mphamvu yosinthasintha komanso kutsutsana

pa kutentha kochepa.

Qingdao Sainuo Chemical Co., Ltd. Ndife opanga sera ya PE, sera ya PP, OPEwax, EVA
