Ethyl Cellulose (EC)
Bayanin Samfura
Ethyl Cellulose (EC) ba shi da ɗanɗano, mai kyauta, fari zuwa haske mai launin toka. Ana amfani dashi a cikin suntan gels, creams, da lotions. Wannan shi ne ethyl ether na cellulose.Ethyl Cellulose EC ne mai narkewa a cikin wani fadi da kewayon kwayoyin kaushi. Yawanci, Ethyl Cellulose EC ana amfani da shi azaman mara kumburi, ɓangaren da ba a iya narkewa a cikin matrix ko tsarin sutura.
Ana iya amfani da Ethyl Cellulose EC don shafa ɗaya ko fiye da sinadaran aiki na kwamfutar hannu don hana su amsawa da wasu kayan ko tare da juna. Yana iya hana discoloration na sauƙi oxidizable abubuwa kamar ascorbic acid, kyale granulations ga sauƙi matsa Allunan da sauran sashi form.EC za a iya amfani da kanta ko a hade tare da ruwa mai narkewa aka gyara don shirya ci saki film coatings cewa ana akai-akai amfani da su. da shafi na micro-barbashi, pellets da Allunan.
Ethyl cellulose ba zai iya narke a cikin ruwa, amma mai narkewa a cikin da yawa Organic kaushi, don haka EC amfani da Allunan, granules na m wakili. Yana iya ƙara taurin Allunan don rage friability Allunan, shi za a iya amfani da matsayin film-forming wakili don inganta bayyanar Allunan, ware dandano, don kauce wa gazawar da ruwa-m kwayoyi don hana influx na metamorphic canji jamiái, inganta. amintaccen ajiyar allunan, kuma ana iya amfani da su azaman kayan ƙarfafa don dorewar allunan sakin.

Ethyl Cellulose shine guduro mai aiki da yawa. Yana aiki azaman mai ɗaure, mai kauri, mai gyara rheology, tsohon fim, da shingen ruwa a cikin aikace-aikace da yawa kamar yadda aka yi bayani a ƙasa:
Adhesives: Ana amfani da Ethyl Cellulose gabaɗaya a cikin narke mai zafi da sauran adhesives na tushen ƙarfi don kyakkyawan yanayin thermoplasticity da ƙarfin kore. Yana narkewa a cikin polymers masu zafi, filastik, da mai.
Rubutun: Ethyl Cellulose yana ba da kariya ta ruwa, tauri, sassauci da babban sheki zuwa fenti da sutura. Hakanan za'a iya amfani dashi a cikin wasu kayan shafa na musamman kamar a cikin takardar tuntuɓar abinci, hasken walƙiya, rufin rufi, enameling, lacquers, varnishes, da rigunan ruwa.
