Iisilinda ezithweswe izidanga okanye iikomityi zokulinganisa zomlinganiselo ochanekileyo we-CMC kunye namanzi.
Ukuxuba ubuchule:
a. Ukuxuba Okubandayo:
Ukongeza i-CMC ngokucothayo kumanzi abandayo ngokuvuselela rhoqo ukuthintela ukuqumbana.
Ukwandisa isantya sokuphazamiseka ngokuthe ngcembe ukuqinisekisa ukusasazwa okufanayo.
Ukuvumela ixesha elaneleyo le-hydration kunye nokuchithwa kwamasuntswana e-CMC.
b. Ukuxuba Okushushu:
Ukufudumeza amanzi kwiqondo lobushushu elifanelekileyo (ngokuqhelekileyo phakathi kwama-50-80°C) phambi kokongeza i-CMC.
Ukufefa ngokucothayo i-CMC emanzini ashushu ngelixa uvuselela rhoqo.
Ukugcina ubushushu phakathi koluhlu olucetyiswayo ukuququzelela ukuhanjiswa kwamanzi ngokukhawuleza kunye nokusasazwa kwe-CMC.
c. Ukuxutywa kwe-High-Chear:
Ukusebenzisa i-high-speed mix mixers okanye i-homogenizers ukufezekisa ukusasazwa okucokisekileyo kunye nokukhawuleza kwe-hydration.
Ukuqinisekisa uhlengahlengiso olufanelekileyo lweseto zomxube ukunqanda ukuveliswa kobushushu obugqithisileyo.
Ukubeka iliso kwi-viscosity kunye nokulungelelanisa iiparitha zokuxuba njengoko zifunekayo ukufezekisa ukuhambelana okufunwayo.
d. Ukuxubana kwe-Ultrasonic:
Ukusebenzisa izixhobo ze-ultrasonic ukudala i-cavitation kunye ne-micro-turbulence kwisisombululo, ukuququzelela ukusabalalisa ngokukhawuleza kweengqungquthela ze-CMC.
Ukuphucula i-frequency kunye noseto lwamandla olusekwe kwiimfuno ezithile zoyilo.
Ukusebenzisa ukuxuba kwe-ultrasonic njengendlela eyongezelelweyo yokuphucula ukusabalalisa kunye nokunciphisa ixesha lokuxuba.
Iingqwalasela kuMgangatho waManzi:
Ukusebenzisa amanzi ahlambulukileyo okanye adibeneyo ukunciphisa ukungcola kunye neengcoliseko ezinokuchaphazela ukusebenza kwe-CMC.
Ukubeka iliso kubushushu bamanzi kunye ne-pH ukuqinisekisa ukuhambelana ne-CMC kunye nokuthintela ukusabela okubi okanye ukuthotywa.
Ukunyibilika kwamanzi kunye nokuNcitshiswa:
Ukuqonda i-hydration kinetics ye-CMC kunye nokuvumela ixesha elaneleyo lokuqukunjelwa okupheleleyo.
Ukubeka iliso kwi-viscosity utshintsho ekuhambeni kwexesha ukuvavanya inkqubela phambili yokuchithwa.
Ukulungelelanisa iiparitha zokuxuba okanye ukongeza amanzi angaphezulu njengoko kufuneka ukufezekisa i-viscosity efunwayo kunye nokuhambelana.
Ulawulo lomgangatho kunye noVavanyo:
Ukuqhuba imilinganiselo ye-viscosity usebenzisa i-viscometers okanye i-rheometers ukuvavanya umgangatho wesisombululo se-CMC.
Ukwenza uhlalutyo lwesayizi yamasuntswana ukuqinisekisa ukusasazeka okufanayo kunye nokungabikho kweeagglomerate.
Ukuqhuba iimvavanyo zokuzinza ukuvavanya ishelufu-ubomi kunye nokusebenza kwesisombululo seCMC phantsi kweemeko ezahlukeneyo zokugcina.
Usetyenziso lweMixube ye-CMC-Amanzi:
Ishishini lokutya: Ukujiya kunye nokuzinzisa iisosi, izinxibo, kunye neemveliso zobisi.
Umzi mveliso wamachiza: Ukuqulunqa ukunqunyanyiswa, i-emulsions, kunye nezisombululo ze-ophthalmic.
Ishishini lezithambiso: Ukudibanisa kwiikhrimu, izinto zokuthambisa, kunye neemveliso zokhathalelo lomntu zolawulo lwe-viscosity kunye nokuzinzisa i-emulsion.
Umzi-mveliso wamalaphu: Ukuphucula i-viscosity yokuprinta intlama kunye nokwakheka kweesayizi.
Ukuxuba i-CMC emanzini yinkqubo ebalulekileyo efuna uqwalaselo ngononophelo lwemiba eyahlukeneyo enjengokukhetha ibakala, ubuchule bokuxuba, ubulunga bamanzi, kunye nemilinganiselo yokulawula umgangatho. Ngokulandela izikhokelo ezichazwe kwesi sikhokelo esibanzi, abavelisi banokuqinisekisa ukusasazwa okusebenzayo kunye nokusebenzayo kwe-CMC, okukhokelela ekuqulunqweni kwezisombululo ezikumgangatho ophezulu kunye nokusebenza okuhambelanayo kuzo zonke izicelo ezahlukeneyo.
