HydroxyethylcelluloseHECwani polymer ne mai narkewar ruwa wanda ba ionic ba wanda yake narkewa a cikin ruwan zafi da sanyi. Jerin HEC na Hydroxyethylcellulose yana da nau'ikan viscosities iri-iri, kuma ruwan da ke cikinsa duk ruwa ne da ba Newtonian ba.
Hydroxyethyl cellulose wani abu ne mai mahimmanci a cikin kayayyakin sinadarai na yau da kullun. Ba wai kawai yana iya inganta danko na kayan kwalliyar ruwa ko emulsion ba, har ma yana inganta warwatsewa da kwanciyar hankali na kumfa.
fa'ida:
1. Yana da ruwa mai kyau sosai.
2. Yana da cikakken daidaito da cikawa.
3. Kyakkyawan kadara mai samar da fina-finai.
4. Yana da matuƙar tsadar aiki.
5. Yana da kyakkyawan matakin maye gurbin don tabbatar da dorewar maganin mildew na dogon lokaci.
Digiri na polymerization:
Akwai ƙungiyoyin hydroxyl guda uku a kan kowace naúrar anhydroglucose a cikin cellulose, wanda ake yi wa magani da alkali a cikin ruwan sodium hydroxide don samun gishirin sodium cellulose, sannan a yi aikin etherification tare da ethylene oxide don samar da hydroxyethyl cellulose ether. A cikin tsarin haɗa hydroxyethyl cellulose, ethylene oxide na iya maye gurbin ƙungiyoyin hydroxyl akan cellulose, kuma a yi aikin polymerization sarkar tare da ƙungiyoyin hydroxyl a cikin ƙungiyoyin da aka maye gurbinsu.
Hydroxyethylcellulose yana da kyawawan halaye na ruwa. Maganin ruwansa yana da santsi da daidaito, tare da kyakkyawan ruwa da daidaitawa. Saboda haka, kayan kwalliya da ke ɗauke da hydroxyethyl cellulose suna da daidaito da cikawa a cikin akwati, kuma suna bazuwa cikin sauƙi a kan gashi da fata idan an shafa su. Ana amfani da shi sosai a cikin kayan kwalliya, wanke-wanke na jiki, sabulun ruwa, gels da kumfa na aski, man goge baki, masu hana gumi, kyallen takarda (jarirai da manya), gels masu shafawa.
Baya ga sarrafa ruwa,hydroxyethyl celluloseyana da kyawawan halaye na ƙirƙirar fim. An tabbatar da cewa fim ɗin da aka yi zai kasance cikin cikakken yanayi a ƙarƙashin na'urar duba madubi ta 350x da 3500x, kuma yana kawo kyakkyawan laushin fata idan aka shafa shi a kayan kwalliya.
