Ukungabonakali kwe-carboxymethyl cellulose ukuthi umkhiqizo uzovunyelwa ngamanzi, ngakho-ke ukungafani komkhiqizo nakho kube yindlela yokwahlulela ukusebenza kwayo. Masifunde kabanzi ngayo:
1) Inani elithile lamanzi lingezwe ohlelweni lokuhlakazeka olutholwe, olungathuthukisa ukuhluka kwezinhlayiya ze-colloidal emanzini, futhi kuyadingeka ukuqinisekisa ukuthi inani lamanzi angeziwe alikwazi ukuncibilikisa i-colloid.
2) Kuyadingeka ukuhlakaza izinhlayiya ze-colloidal ku-siquid Carrier medium medium ezingekho emthethweni, ama-infoluble kuma-gelble ancibilikayo noma ngaphandle kwamanzi, kepha kufanele kube mkhulu kunevolumu yezinhlayiya ezikhohlakele ukuze zihlakazeke ngokuphelele . zingu-monohydric utshwala njenge-methanol ne-ethanol, ethylene glycol, acetone, njll.
3) Usawoti oshukunyiswa amanzi kufanele wengezwe oketshebeni ophethe, kepha usawoti akakwazi ukusabela nge-colloid. Umsebenzi wayo oyinhloko ukuvikela ijeli elinyibilikisiwe lamanzi ukuthi lisuse unamathisela noma ukuzulazula kanye nezulu lapho kuphumula. Esetshenziswa kakhulu yi-sodium chloride nokunye.
4) Kuyadingeka ukwengeza umenzeli osomisayo ku-orgain ketsheli we-carrier ukuvimbela into yemvelo ye-gel. I-ejenti yokumisa eyinhloko ingaba Glycerin, i-hydroxypropyl methylcellulose, njll. I-carboxymethyl cellulose, uma i-glycerol isetshenziswa njenge-ejenti elisamisayo, umthamo ojwayelekile cishe u-3% -10% woketshezi lwenkampani.
I-5) Esezinhlelweni ze-alkalization kanye nokuthengwa, kufanele kufakwe ama-surfic noma ama-chationic noma ama-surfiic, futhi kufanele achithwe ku-uketshezi othwala uketshezi ukuze ahambisane nama-colloids. Ama-surficant asetshenziswa kaningi yi-lauryl sulfate, i-glycerin monoester, i-propylene glycol fattuty acid ester, umthamo wayo cishe ngo-0.05% -5% we-orgain ketsheli yenethiwekhi.
