HEC ya zinthu zapadera zodzikongoletsera

HydroxyethylcelluloseHECndi polima yosasungunuka m'madzi yomwe imasungunuka m'madzi otentha komanso ozizira. Hydroxyethylcellulose series HEC ili ndi mitundu yosiyanasiyana ya kukhuthala, ndipo madzi onse ndi madzi osakhala a Newtonian.

Hydroxyethyl cellulose ndi chinthu chofunikira kwambiri mu mankhwala a tsiku ndi tsiku. Sichimangowonjezera kukhuthala kwa zodzoladzola zamadzimadzi kapena emulsion, komanso chimathandizira kufalikira ndi kukhazikika kwa thovu.

ubwino:
1. Ali ndi madzi okwanira bwino.
2. Ili ndi kukhazikika kwakukulu komanso kudzaza.
3. Kapangidwe kabwino kwambiri kopanga filimu.
4. Ili ndi magwiridwe antchito okwera mtengo kwambiri.
5. Ili ndi mlingo wabwino kwambiri wosinthira kuti iwonetsetse kuti mankhwalawo amakhala olimba kwa nthawi yayitali motsutsana ndi chimfine.

Digiri ya polymerization:
Pali magulu atatu a hydroxyl pa gawo lililonse la anhydroglucose mu cellulose, lomwe limachiritsidwa ndi alkali mu yankho la sodium hydroxide lamadzimadzi kuti lipeze mchere wa sodium wa cellulose, kenako limadutsa mu etherification reaction ndi ethylene oxide kuti lipange hydroxyethyl cellulose ether. Pakupanga hydroxyethyl cellulose, ethylene oxide imatha kulowa m'malo mwa magulu a hydroxyl pa cellulose, ndikudutsa mu chain polymerization reaction ndi magulu a hydroxyl m'magulu osinthidwa.

Hydroxyethylcellulose ili ndi mphamvu zabwino kwambiri zothira madzi. Yankho lake lamadzi ndi losalala komanso lofanana, lokhala ndi madzi okwanira komanso lofanana. Chifukwa chake, zodzoladzola zokhala ndi hydroxyethyl cellulose zimakhala ndi kukhazikika bwino komanso kudzaza bwino m'chidebe, ndipo zimafalikira mosavuta patsitsi ndi khungu zikagwiritsidwa ntchito. Zimagwiritsidwa ntchito kwambiri mu zodzoladzola, zotsukira thupi, sopo wamadzimadzi, ma gels ometa ndi thovu, mankhwala otsukira mano, ma deodorants olimba oletsa thukuta, minofu (makanda ndi akuluakulu), ma gels opaka mafuta.

Kuwonjezera pa kulamulira madzi,hydroxyethyl celluloseIli ndi mawonekedwe abwino kwambiri opangira filimu. Filimu yopangidwayo imatsimikizika kuti idzakhala bwino kwambiri poyesa magalasi pa 350x ndi 3500x, ndipo imabweretsa khungu losalala bwino ikagwiritsidwa ntchito pazodzoladzola.
