Hydroxyethyl cellulose wani polymer ne mai narkewar ruwa wanda ba ionic ba wanda aka yi shi da cellulose, wani abu na halitta na polymer, ta hanyar jerin hanyoyin sinadarai. Abu ne mai kauri fari ko rawaya, mara wari kuma mara dandano, wanda za'a iya narkar da shi a cikin ruwan sanyi da ruwan zafi, kuma saurin narkewa yana ƙaruwa tare da ƙaruwar zafin jiki. Gabaɗaya, ba ya narkewa a cikin yawancin abubuwan narkewa na halitta. Ana amfani da shi azaman mai kauri da mai daidaita a cikin fenti na latex. Yana da sauƙin warwatse a cikin ruwan sanyi tare da ƙimar pH ƙasa da 7 ko daidai yake da shi, amma yana da sauƙin taruwa a cikin ruwan alkaline, don haka gabaɗaya ana shirya shi gaba ɗaya don amfani daga baya, ko kuma ruwan acid mai rauni ko maganin halitta an yi shi da slurry, kuma ana iya haɗa shi da sauran granular. Sinadaran an gauraya su tare.
Halayen hydroxyethyl cellulose:
HEC yana narkewa a cikin ruwan zafi ko sanyi, kuma baya zubewa a yanayin zafi mai yawa ko tafasa, wanda ke sa ya sami nau'ikan halaye masu yawa na narkewa da ɗanko, da kuma gelation mara zafi.
Yana iya rayuwa tare da nau'ikan polymers masu narkewa cikin ruwa, surfactants, da gishiri, kuma kyakkyawan mai kauri ne na colloidal don mafita waɗanda ke ɗauke da electrolytes masu yawan taro.
Ƙarfin riƙe ruwa ya ninka na methyl cellulose sau biyu, kuma yana da ingantaccen tsarin kwarara.
Idan aka kwatanta da methyl cellulose da aka sani da hydroxypropyl methyl cellulose, ikon watsawa na HEC shine mafi muni, amma ikon kariya na colloid shine mafi ƙarfi.
Kyakkyawan gini; yana da fa'idodin adana aiki, ba shi da sauƙin digawa, hana sag, kyakkyawan hana fesawa, da sauransu.
Kyakkyawan jituwa tare da nau'ikan surfactants da abubuwan kiyayewa daban-daban da ake amfani da su a fenti na latex.
Dankowar ajiya tana da ƙarfi, wanda zai iya hana hydroxyethyl cellulose gabaɗaya rage dankowar fenti na latex yayin ajiya saboda ruɓewar enzymes.
