Hydroxyethyl Cellulose (HEC) Polymer mai narkewa ne wanda ba na ionic ba wanda aka yadu ana amfani dashi a cikin sutura, kayan kwalliya, kayan wanka da kayan gini. Saboda kyawawan kauri, daidaitawa da abubuwan samar da fim, yana buƙatar narkar da shi cikin ruwa don samar da ingantaccen bayani idan aka yi amfani da shi.

Yi amfani da ruwa mai tsafta ko ruwa mai tsafta don guje wa ƙazanta da ke shafar tasirin rushewar.
Hydroxyethyl cellulose yana kula da zafin jiki, kuma za'a iya daidaita yawan zafin jiki na ruwa kamar yadda ake buƙata yayin tsarin narkewa (ruwa mai sanyi ko hanyar ruwan dumi).
2. Hanyoyi biyu na rushewar da aka saba amfani da su
(1) Hanyar ruwan sanyi
A hankali yayyafa foda: A cikin akwati da aka cika da ruwan sanyi, sannu a hankali kuma a yayyafa HEC foda a cikin ruwa don kauce wa ƙara yawan foda a lokaci guda don haifar da caking.
Juyawa da tarwatsawa: Yi amfani da abin motsa jiki don motsawa a cikin ƙananan gudu don watsa foda a cikin ruwa don samar da dakatarwa. Agglomeration na iya faruwa a wannan lokacin, amma kada ku damu.
Tsaye da wetting: Bari watsawa ya tsaya na tsawon sa'o'i 0.5-2 don ba da damar foda ya sha ruwa gaba daya kuma ya kumbura.
Ci gaba da motsawa: Dama har sai maganin ya zama cikakke cikakke ko kuma ba shi da jin dadi, wanda yawanci yana ɗaukar minti 20-40.
(2) Hanyar ruwan dumi (hanyar watsa ruwan zafi)
Pre-watsawa: Ƙara ƙaramin adadinHECfoda zuwa 50-60 ℃ ruwan zafi kuma motsawa da sauri don tarwatsa shi. Yi hankali don kauce wa foda agglomeration.
Ruwan sanyi: Bayan an tarwatsa foda da farko, ƙara ruwan sanyi don tsomawa zuwa taro mai niyya kuma motsawa lokaci guda don hanzarta rushewa.
Sanyaya da tsayawa: Jira mafita don kwantar da hankali kuma tsaya na dogon lokaci don ba da damar HEC ta narke gaba ɗaya.
3. Mahimmin dabarun warwarewa
Guji agglomeration: Lokacin ƙara HEC, yayyafa shi a hankali kuma ku ci gaba da motsawa. Idan an sami agglomerations, yi amfani da sieve don tarwatsa foda.
Rarraba yawan zafin jiki: Hanyar ruwan sanyi ta dace da mafita waɗanda ke buƙatar adana na dogon lokaci, kuma hanyar ruwan dumi na iya rage lokacin narkewa.
Lokacin rushewa: Ana iya amfani dashi lokacin da bayyananniyar gaskiya ta cika har zuwa daidaitattun, wanda yawanci yana ɗaukar mintuna 20 zuwa sa'o'i da yawa, dangane da ƙayyadaddun bayanai da tattarawar HEC.
4. Bayanan kula
Matsakaicin Magani: Gabaɗaya ana sarrafa shi tsakanin 0.5% -2%, kuma ana daidaita ƙayyadaddun ƙaddamarwa bisa ga ainihin buƙatun.
Ajiye da kwanciyar hankali: Maganin HEC yakamata a adana shi a cikin akwati da aka rufe don gujewa kamuwa da cuta ko fallasa yanayin yanayin zafin jiki wanda ke shafar kwanciyar hankali.
Ta hanyar matakan da ke sama,hydroxyethyl celluloseza a iya narkar da yadda ya kamata a cikin ruwa don samar da uniform da m bayani, wanda ya dace da daban-daban aikace-aikace yanayin.
