Bayanin samfur:
Hydroxyethyl cellulose (HEC) fari ne ko rawaya mai haske, mara wari, foda mara guba. An shirya shi daga asali cellulose da ethylene oxide (ko chloroethane) ta hanyar etherification. Ita ce ether mai narkewa mara-ionic cellulose. Saboda HEC cellulose yana da kyawawan halaye na thickening, dakatarwa, watsawa, emulsification, adhesion, samuwar fim, kariya daga danshi, da kuma kariya daga colloids, ana amfani dashi sosai a cikin hakar man fetur, sutura, gine-gine, magani da abinci, yadi, takarda, da kuma sauran filayen.
Aikace-aikace:
1. Hydroxyethyl cellulose foda za a iya narkar da a cikin ruwan zafi da sanyi, kuma ba zai yi hazo a lokacin da mai tsanani ko Boiled. Saboda haka, yana da nau'i mai yawa na solubility da halayen danko da rashin thermogelability.
2. HEC na iya zama tare da wasu polymers masu narkewa da ruwa, masu surfactants, da salts. HEC shine ingantacciyar kauri mai kauri wanda ke dauke da manyan hanyoyin magance dielectric.
3. Ƙarfin ajiyar ruwa ya ninka na methylcellulose sau biyu, kuma yana da kyakkyawan tsari na kwarara.
4. Idan aka kwatanta da methylcellulose da hydroxypropylmethylcellulose, HEC yana da ƙarfin colloid mafi ƙarfi.
Masana'antar Gina: Ana iya amfani da HEC azaman wakili mai riƙe danshi da mai hana saitin siminti.
Masana'antar hako mai: Ana iya amfani da shi azaman mai kauri da siminti don ruwan rijiyar mai. Ruwan hakowa tare da HEC na iya inganta ingantaccen aikin hakowa bisa ƙarancin aikin abun ciki.
Coating Industry: HEC na iya taka rawa wajen kauri, emulsifying, tarwatsawa, daidaitawa da riƙe ruwa don kayan latex. An kwatanta shi da tasiri mai mahimmanci mai zurfi, kyakkyawan launi mai launi, samar da fim, da kwanciyar hankali na ajiya.
Takarda da Tawada: Ana iya amfani da shi azaman wakili mai ƙima akan takarda da allo, azaman mai kauri da dakatarwa don tawada na tushen ruwa.
Chemicals na yau da kullun: HEC wakili ne mai inganci mai samar da fim, manne, mai kauri, mai daidaitawa da rarrabawa a cikin shamfu, masu gyaran gashi, da kayan kwalliya.
