Cellulose ether HE jerin, wato, hydroxyethyl cellulose, fari ne zuwa madara fari foda. Ana iya narkar da shi a cikin ruwan zafi da ruwan sanyi, amma ba shi da sauƙi a narke a cikin kwayoyin halitta. Jinshi iri cellulose ether HE jerin samfuran suna da ƙarfin riƙe ruwa, ƙirƙirar fim, juriya na gishiri da tasirin kauri. Hakanan yana da kyakkyawar dacewa launi kuma shine ingantaccen ƙari a aikace-aikacen latex.

Hydroxyethyl cellulose HEC shine mai kauri da aka saba amfani dashi a cikin sutura kuma yana da fa'idodi masu zuwa:

(1) Ƙarfi mai ƙarfi Hydroxyethyl cellulose HEC wani nau'in polymer ne wanda ba shi da ruwa mai narkewa wanda za'a iya amfani dashi a cikin kewayon pH (2-12). Ana iya haɗa shi tare da abubuwan da aka gyara a cikin suturar gabaɗaya (kamar su pigments, additives, salts soluble salts da electrolytes) ba tare da abubuwan ban mamaki ba. da

(2) Kyakkyawan gini. A shafi thickened da hydroxyethyl cellulose HEC yana da pseudoplasticity, don haka za a iya amfani da brushing, spraying, abin nadi shafi da sauran gina hanyoyin. Abvantbuwan amfãni, daidaitawa kuma ya fi kyau. da

(3) Babu wani mummunan tasiri akan fim ɗin shafa. Saboda inconspicuous ruwa surface tashin hankali halaye na HEC ruwa mai ruwa bayani, ba sauki a kumfa a lokacin gini da kuma samar, kuma akwai kasa hali don samar da volcanic ramukan da pinholes. da

(4) Kyakkyawan haɓaka launi. Hydroxyethyl cellulose HEC yana da m miscibility tare da mafi binders da colorants, sabõda haka, shirya fenti yana da kyau launi kwanciyar hankali da daidaito.

(5) Kyakkyawan kwanciyar hankali. A lokacin ajiya na fenti, zai iya kula da dakatarwa da rarrabawa na pigment, ba tare da matsalolin iyo da furanni ba. Akwai ƙarancin ruwa a saman fenti. Lokacin da ma'ajin zafin jiki ya canza, dankon sa ya kasance iri ɗaya. karin kwanciyar hankali.
