I-dispersibility ye-carboxymethyl cellulose ukuthi umkhiqizo uzobola emanzini, ngakho-ke ukuhlakazeka komkhiqizo kuye kwaba yindlela yokwahlulela ukusebenza kwawo.Masifunde okwengeziwe ngayo:
I-1) Inani elithile lamanzi lengezwa ohlelweni olutholakalayo lokuhlakazeka, olungathuthukisa ukuhlakazeka kwezinhlayiya ze-colloidal emanzini, futhi kuyadingeka ukuqinisekisa ukuthi inani lamanzi elingeziwe alikwazi ukuhlakaza i-colloid.
2) Kudingekile ukusabalalisa izinhlayiya ze-colloidal endaweni ethwala uketshezi exubene emanzini, engancibiliki emanzini noma ngaphandle kwamanzi, kodwa kufanele ibe nkulu kunomthamo wezinhlayiya ze-colloidal ukuze zihlakazeke ngokugcwele. .ama-alcohol e-monohydric afana ne-methanol ne-ethanol, i-ethylene glycol, i-acetone, njll.
3) Usawoti oncibilikayo emanzini kufanele wengezwe kuketshezi oluthwalayo, kodwa usawoti awukwazi ukusabela nge-colloid.Umsebenzi wayo oyinhloko ukuvimbela ijeli encibilikayo emanzini ukuthi ingenze ukunamathisela noma ukuhlangana kanye nemvula lapho iphumule.Okuvame ukusetshenziswa yi-sodium chloride nokunye.
4) Kuyadingeka ukwengeza i-ejenti yokumisa oketshezini oluthwalayo ukuvimbela ukwenzeka kwemvula yejeli.I-ejenti elengayo eyinhloko ingaba i-glycerin, i-hydroxypropyl methylcellulose, njll. I-ejenti elengayo kufanele inyibilike esithwalweni esiwuketshezi futhi ihambisane ne-colloid.Ku-carboxymethyl cellulose, uma i-glycerol isetshenziswa njenge-ejenti yokumisa, umthamo ojwayelekile cishe u-3% -10% woketshezi oluthwalayo.
5) Enqubweni ye-alkalization kanye ne-etherification, ama-cationic noma ama-nonionic surfactants kufanele angezwe, futhi kufanele ahlakazwe kusithwali se-liquid ukuze ahambisane nama-colloid.Ama-surfactants asetshenziswa kakhulu yi-lauryl sulfate, i-glycerin Monoester, i-propylene glycol fatty acid ester, umthamo wayo ucishe ube ngu-0.05% -5% we-liquid carrier.
