A cikin tsarin fenti, hydroxyethyl cellulose (HEC) wani abu ne da aka saba amfani da shi wajen gyara kauri da kuma gyaran rheology wanda zai iya inganta kwanciyar hankali na ajiya, daidaita da kuma halayen ginin fenti. Domin a ƙara hydroxyethyl cellulose a cikin fenti da kuma tabbatar da cewa yana aiki yadda ya kamata, akwai buƙatar a bi wasu matakai da matakan kariya. Tsarin takamaiman shine kamar haka:
1. Halayen hydroxyethyl cellulose
Hydroxyethyl cellulose wani polymer ne mai narkewar ruwa wanda ba ionic ba, wanda ke da kyawawan halaye na kauri, samar da fim, riƙe ruwa, dakatarwa da kuma emulsifying. Ana amfani da shi sosai a cikin fenti na ruwa, manne, yumbu, tawada da sauran kayayyaki. Ana samunsa ta hanyar maye gurbin wani ɓangare na rukunin hydroxyl akan sarkar ƙwayoyin cellulose da ƙungiyoyin hydroxyethyl, don haka yana da kyakkyawan narkewar ruwa.
Babban ayyukan HEC a cikin fenti sune:

Tasirin dakatarwa: Yana iya warwatsewa daidai gwargwado da daidaita barbashi masu ƙarfi kamar launuka da abubuwan cikawa don hana su zama.
Tasirin riƙe ruwa: Inganta riƙe ruwa na fim ɗin rufewa, tsawaita lokacin buɗewa, da kuma inganta tasirin jika fenti.
Kula da Rheology: daidaita ruwa da daidaita murfin, da kuma inganta matsalar alamar goge yayin gini.
2. Matakan ƙarin hydroxyethyl cellulose
Matakin Kafin Narkewa A ainihin aiki, ana buƙatar a warwatse hydroxyethyl cellulose daidai gwargwado kuma a narkar da shi ta hanyar tsarin kafin narkewa. Domin tabbatar da cewa cellulose zai iya taka rawar da ta taka gaba ɗaya, yawanci ana ba da shawarar a narkar da shi da ruwa da farko, maimakon ƙara shi kai tsaye a cikin murfin. Matakan takamaiman sune kamar haka:
Zaɓi mai narkewa mai dacewa: yawanci ana amfani da ruwan da aka narkar da shi azaman mai narkewa. Idan akwai wasu mai narkewar halitta a cikin tsarin rufewa, yanayin narkewar yana buƙatar daidaitawa bisa ga halayen mai narkewar.
A yayyafa hydroxyethyl cellulose a hankali: A yayyafa foda hydroxyethyl cellulose a hankali a hankali yayin da ake jujjuya ruwan don hana haɗuwa. Ya kamata saurin juyawa ya kasance a hankali don guje wa rage saurin narkewar cellulose ko samar da "colloids" saboda ƙarfin yankewa da yawa.
Narkewar da ke tsayawa: Bayan yayyafa hydroxyethyl cellulose, yana buƙatar a bar shi ya tsaya na tsawon lokaci (yawanci na mintuna 30 zuwa awanni da yawa) don tabbatar da cewa cellulose ɗin ya kumbura gaba ɗaya kuma ya narke a cikin ruwa. Lokacin narkewar ya dogara da nau'in cellulose, zafin narkewa da yanayin juyawa.
Daidaita zafin narkewa: Ƙara zafin jiki yana taimakawa wajen hanzarta narkewar hydroxyethyl cellulose. Yawanci ana ba da shawarar a sarrafa zafin ruwan tsakanin 20℃-40℃. Yawan zafin jiki na iya haifar da lalacewar cellulose ko lalacewar ruwan.
Daidaita ƙimar pH na maganin Rashin narkewar hydroxyethyl cellulose yana da alaƙa da ƙimar pH na maganin. Yawanci yana narkewa mafi kyau a ƙarƙashin yanayi mai tsaka tsaki ko ɗan alkaline, tare da ƙimar pH tsakanin 6-8. A lokacin narkewar, ana iya daidaita ƙimar pH ta hanyar ƙara ammonia ko wasu abubuwan alkaline kamar yadda ake buƙata.
Ƙara maganin hydroxyethyl cellulose a cikin tsarin shafa bayan narkewa, ƙara maganin a cikin shafa. A lokacin ƙarawa, ya kamata a ƙara shi a hankali a kuma ci gaba da juyawa don tabbatar da isasshen haɗuwa da matrix ɗin shafa. A lokacin haɗawa, ya zama dole a zaɓi saurin motsawa mai dacewa bisa ga tsarin daban-daban don hana tsarin kumfa ko lalacewar cellulose saboda ƙarfin yankewa da yawa.
Daidaita Danko Bayan ƙara hydroxyethyl cellulose, ana iya sarrafa danko na murfin ta hanyar daidaita adadin da aka ƙara. Gabaɗaya, adadin hydroxyethyl cellulose da aka yi amfani da shi yana tsakanin 0.3%-1.0% (idan aka kwatanta da jimlar nauyin murfin), kuma takamaiman adadin da aka ƙara yana buƙatar a daidaita shi ta hanyar gwaji bisa ga buƙatun tsari na murfin. Yawan ƙarin zai iya haifar da girman danko da rashin ruwa, wanda ke shafar aikin gini; yayin da rashin isasshen ƙarin ba zai iya taka rawar kauri da dakatarwa ba.
Gudanar da gwaje-gwajen daidaito da daidaiton ajiya Bayan ƙara hydroxyethyl cellulose da daidaita dabarar rufewa, ana buƙatar gwada aikin ginin murfin, gami da daidaitawa, sag, sarrafa alamar goge, da sauransu. A lokaci guda, ana buƙatar gwajin daidaiton ajiyar murfin don lura da laka bayan tsayawa na ɗan lokaci, canjin danko, da sauransu, don tantance daidaiton hydroxyethyl cellulose.
3. Gargaɗi
Hana haɗuwa: A lokacin narkewar ruwa, hydroxyethyl cellulose yana da sauƙin sha ruwa da kumbura, don haka yana buƙatar a yayyafa shi a cikin ruwan a hankali a tabbatar da isasshen motsawa don hana samuwar ƙuraje. Wannan babban haɗin gwiwa ne a cikin aikin, in ba haka ba yana iya shafar saurin narkewa da daidaito.
A guji ƙarfin yankewa mai yawa: Lokacin ƙara cellulose, saurin juyawa bai kamata ya yi yawa ba don guje wa lalata sarkar ƙwayoyin cellulose saboda ƙarfin yankewa mai yawa, wanda ke haifar da raguwar aikin kauri. Bugu da ƙari, a cikin samar da shafi na gaba, ya kamata a guji amfani da kayan aikin yankewa mai yawa gwargwadon iko.
Kula da zafin narkewa: Lokacin da ake narkar da hydroxyethyl cellulose, zafin ruwan bai kamata ya yi yawa ba. Ana ba da shawarar a sarrafa shi a 20℃-40℃. A yanayin zafi mai yawa, cellulose na iya lalacewa, wanda ke haifar da raguwar tasirin kauri da danko.
Ajiye maganin: Gabaɗaya ana buƙatar a shirya kuma a yi amfani da maganin hydroxyethyl cellulose nan take. Ajiyewa na dogon lokaci zai shafi danko da kwanciyar hankali. Yawanci ana ba da shawarar a shirya maganin da ake buƙata a ranar da aka samar da fenti don kiyaye ingantaccen aikinsa.
Ƙara sinadarin hydroxyethyl cellulose a cikin fenti ba wai kawai wani tsari ne mai sauƙi na haɗakar jiki ba, har ma yana buƙatar a haɗa shi da ainihin buƙatun tsari da ƙayyadaddun bayanai na aiki don tabbatar da cewa an yi amfani da kauri, dakatarwa da kuma riƙe ruwa sosai. A lokacin ƙarawa, a kula da matakin kafin narkewa, kula da zafin narkewa da ƙimar pH, da kuma cikakken haɗuwa bayan ƙarawa. Waɗannan cikakkun bayanai za su shafi inganci da kwanciyar hankali na fenti kai tsaye.
