HEC kwa zodzikongoletsera kalasi wapadera mankhwala

Hydroxyethyl celluloseHECndi polima yosungunuka m'madzi yopanda ion yomwe imasungunuka m'madzi otentha komanso ozizira. Hydroxyethylcellulose mndandanda HEC ali osiyanasiyana viscosities, ndi njira amadzimadzi zonse sanali Newtonian madzimadzi.

Hydroxyethyl cellulose ndi chowonjezera chofunikira pazamankhwala atsiku ndi tsiku. Iwo sangakhoze kusintha mamasukidwe akayendedwe a madzi kapena emulsion zodzoladzola, komanso kusintha kubalalitsidwa ndi thovu bata.

ubwino:
1.Ali ndi madzi abwino kwambiri.
2. Lili ndi kugwirizana kwakukulu ndi chidzalo.
3. Katundu wabwino kwambiri wopanga mafilimu.
4. Ili ndi magwiridwe antchito okwera kwambiri.
5.Ili ndi digiri yabwino kwambiri yoloweza m'malo kuti zitsimikizire kukhazikika kwa nthawi yayitali kwa anti-mildew.

Digiri ya Polymerization:
Pali magulu atatu a hydroxyl pa unit iliyonse ya anhydroglucose mu cellulose, yomwe imathandizidwa ndi alkali mumadzimadzi amadzimadzi a sodium hydroxide kuti apeze mchere wamchere wa sodium, ndiyeno amakumana ndi etherification ndi ethylene oxide kupanga hydroxyethyl cellulose ether. Popanga hydroxyethyl cellulose, ethylene oxide imatha kulowa m'malo mwa magulu a hydroxyl pa cellulose, ndikukumana ndi unyolo wama polymerization ndi magulu a hydroxyl m'magulu olowa m'malo.

Hydroxyethyl cellulose ili ndi mphamvu zabwino kwambiri za hydration. Njira yake yamadzimadzi ndi yosalala komanso yofananira, yokhala ndi madzi abwino komanso yokhazikika. Choncho, zodzoladzola zomwe zili ndi hydroxyethyl cellulose zimakhala bwino komanso zodzaza mumtsuko, ndipo zimafalikira mosavuta pa tsitsi ndi khungu zikagwiritsidwa ntchito. Amagwiritsidwa ntchito kwambiri poyeretsa, kutsuka thupi, sopo wamadzimadzi, kumeta ma gels ndi thovu, mankhwala otsukira mano, zoziziritsa kukhosi zolimba, minyewa (makanda ndi akulu), ma gels opaka mafuta.

Kuphatikiza pa kuwongolera madzi,hydroxyethyl celluloseali ndi zida zabwino kwambiri zopangira mafilimu. Kanema wopangidwayo amatsimikizika kuti adzakhala wathunthu pansi pa 350x ndi 3500x sikani yagalasi, ndipo imabweretsa kumveka bwino kwapakhungu ikagwiritsidwa ntchito pazodzola.
