Dumama da sauran ƙarfi:
Don hanzarta aikin narkar da, ana iya dumama sauran ƙarfi yadda ya kamata, amma gabaɗaya bai kamata ya wuce 50 ° C don guje wa yuwuwar lalata yanayin zafi ba. Yanayin zafin ruwa tsakanin 30 ° C da 50 ° C yana da kyau.
A hankali ƙara HEC foda:
Sannu a hankali yayyafa HEC foda a cikin ruwan zafi. Don kauce wa agglomeration, ƙara shi ta hanyar sieve ko kuma a yayyafa shi a hankali. Tabbatar cewa HEC foda yana ko'ina tarwatsa yayin aikin motsawa.
Ci gaba da motsawa:
A lokacin aikin motsa jiki, ci gaba da ƙara HEC foda a hankali don tabbatar da cewa foda ya tarwatsa cikin ruwa. Gudun motsawa bai kamata ya kasance da sauri ba don hana kumfa da agglomeration. Ana ba da shawarar motsawa matsakaicin matsakaici.
Rushewar Tsaye: Bayan cikakken tarwatsawa, yawanci yakan zama dole a tsaya na ɗan lokaci (yawanci sa'o'i da yawa ko ya fi tsayi) don ba da damar HEC ta narke gaba ɗaya kuma ta samar da ingantaccen bayani. Lokacin tsayawa ya dogara ne akan nauyin kwayoyin HEC da ƙaddamar da maganin.
Daidaita danko: Idan ana buƙatar gyara danko, adadin HEC na iya ƙarawa ko rage daidai. Bugu da ƙari, ana iya daidaita shi ta ƙara electrolytes, canza darajar pH, da dai sauransu.
Kariya a cikin rushewa
Guji agglomeration: Hydroxyethyl cellulose yana da sauƙin haɓakawa, don haka lokacin ƙara foda, kula da kulawa ta musamman don yayyafa shi daidai. Ana iya amfani da sieve ko wata na'ura mai tarwatsawa don taimakawa daidai gwargwado.
Matsakaicin zafin jiki: zafin jiki mai ƙarfi bai kamata ya zama babba ba, in ba haka ba yana iya haifar da lalatawar thermal na HEC kuma yana shafar aikin maganin. Yawancin lokaci ya fi dacewa don sarrafa shi tsakanin 30 ° C da 50 ° C.
Hana iska daga shiga: Ka guji motsawa da sauri don hana iska daga shigar da maganin don samar da kumfa. Kumfa za su yi tasiri daidai da daidaiton bayani.
Zaɓi kayan aikin da ya dace: Zaɓi kayan aikin motsa jiki daidai gwargwadon ɗankowar maganin. Don ƙananan danko mafita, za a iya amfani da talakawa stirrers; don mafita mai girma-danko, ana iya buƙatar mai ƙarfi mai ƙarfi.
Adana da adanawa:
Ya kamata a adana maganin HEC da aka narkar a cikin akwati da aka rufe don hana danshi ko gurɓatawa. Lokacin da aka adana na dogon lokaci, kauce wa hasken rana kai tsaye da yanayin zafi mai zafi don tabbatar da kwanciyar hankali na maganin.
Matsalolin gama gari da mafita
Rashin daidaituwa:
Idan rashin daidaituwa ya faru, yana iya zama saboda ana yayyafa foda da sauri ko kuma an motsa shi sosai. Maganin shine don inganta daidaituwa na motsawa, ƙara lokacin motsawa, ko daidaita saurin ƙara foda yayin motsawa.
Ƙirƙirar kumfa:
Idan babban adadin kumfa ya bayyana a cikin maganin, za'a iya rage kumfa ta hanyar rage saurin motsawa ko barin ta tsaya na dogon lokaci. Don kumfa da suka riga sun samo asali, ana iya amfani da wakili na degassing ko za a iya amfani da maganin ultrasonic don cire su.
Dankin Magani yayi yawa ko kadan
Lokacin da danko bayani bai cika buƙatun ba, ana iya sarrafa shi ta hanyar daidaita adadin HEC. Bugu da ƙari, daidaita ƙimar pH da ƙarfin ionic na maganin kuma zai iya rinjayar danko.
Kuna iya narkar da hydroxyethyl cellulose yadda ya kamata kuma ku sami daidaitaccen bayani kuma barga. Kwarewar ingantattun matakai na aiki da taka tsantsan na iya haɓaka tasirin hydroxyethyl cellulose a aikace-aikace daban-daban.
