Hydroxyethyl cellulose wani nau'in polymer ne wanda ba na ionic mai narkewa da ruwa wanda aka yi daga cellulose, kayan polymer na halitta, ta hanyar tsarin sinadarai. Wani abu ne mai fari ko rawaya, mara wari da ɗanɗano mai ɗanɗano mai ɗanɗano, wanda za'a iya narkar da shi a cikin ruwan sanyi da ruwan zafi, kuma adadin narkarwar yana ƙaruwa tare da haɓakar zafin jiki. Gabaɗaya, ba ya narkewa a yawancin kaushi na halitta. Ana amfani dashi azaman thickener da stabilizer a cikin fenti na latex. Yana da sauƙin watsawa a cikin ruwan sanyi tare da ƙimar pH ƙasa da ko daidai da 7, amma yana da sauƙin haɓakawa a cikin ruwa na alkaline, don haka ana shirya gabaɗaya gabaɗaya don amfani da gaba, ko ruwa mai rauni ko ruwa mai ƙarfi an sanya shi cikin slurry. , kuma ana iya hada shi da sauran granular Abubuwan da aka bushe sun bushe a hade tare.
Halayen hydroxyethyl cellulose:
HEC yana narkewa a cikin ruwan zafi ko ruwan sanyi, kuma baya tasowa a babban zafin jiki ko tafasa, wanda ya sa yana da nau'i mai yawa na solubility da danko, da kuma ba mai zafi ba.
Yana iya zama tare da ɗimbin kewayon sauran polymers masu narkewar ruwa, surfactants, da salts, kuma yana da kyakkyawan kauri mai ƙarfi na colloidal don mafita mai ɗauke da manyan electrolytes.
Ƙarfin riƙewar ruwa ya ninka na methyl cellulose sau biyu, kuma yana da mafi kyawun tsarin kwarara.
Idan aka kwatanta da gane methyl cellulose da hydroxypropyl methyl cellulose, da dispersing ikon HEC ne mafi muni, amma m colloid ikon ne mafi karfi.
Kyakkyawan gini; yana da fa'idodi na ceton aiki, ba sauƙin drip ba, anti-sag, anti-splash mai kyau, da sauransu.
Kyakkyawan dacewa tare da nau'ikan surfactants da abubuwan kiyayewa waɗanda aka yi amfani da su a cikin fenti na latex.
Dankin ajiya yana da karko, wanda zai iya hana janar hydroxyethyl cellulose daga rage danko na latex fenti a lokacin ajiya saboda bazuwar enzymes.
