I-dispersibility ye-carboxymethyl cellulose kukuba imveliso iya kuchithwa emanzini, ngoko ke ukuchithwa kwemveliso kuye kwaba yindlela yokugweba ukusebenza kwayo.Masifunde ngakumbi ngayo:
I-1) Umlinganiselo othile wamanzi wongezwa kwinkqubo yokusabalalisa efunyenweyo, enokuphucula ukuchithwa kwe-colloidal particles emanzini, kwaye kuyimfuneko ukuqinisekisa ukuba umlinganiselo wamanzi ongeziweyo awukwazi ukutshabalalisa i-colloid.
2) Kuyimfuneko ukusasaza amasuntswana e-colloidal kwindawo yokuthwala ulwelo exubeneyo emanzini, enganyibilikiyo kwiigels ezinyibilikayo emanzini okanye ngaphandle kwamanzi, kodwa kufuneka ibe nkulu kunomthamo we-colloidal particles ukuze zisasazwe ngokupheleleyo. .zitywala ze-monohydric ezifana ne-methanol kunye ne-ethanol, i-ethylene glycol, i-acetone, njl.
I-3) Ityuwa e-soluble yamanzi kufuneka ifakwe kwi-carrier carrier, kodwa ityuwa ayinakusabela nge-colloid.Umsebenzi wayo oyintloko kukuthintela i-gel e-soluble yamanzi ekwenzeni i-paste okanye i-coagulating kunye nemvula xa iphumla.Ngokuqhelekileyo zisetyenziselwa i-sodium chloride kunye nokunye.
4) Kuyimfuneko ukuba ungeze i-agent yokumisa kwi-carrier carrier ukukhusela i-phenomenon ye-gel precipitation.I-agent eyintloko yokumisa ingaba yi-glycerin, i-hydroxypropyl methylcellulose, njl njl. I-agent yokumisa kufuneka i-soluble kwi-carrier carrier kwaye ihambelane ne-colloid.Kwi-carboxymethyl cellulose, ukuba i-glycerol isetyenziswe njenge-arhente yokumisa, i-dosage eqhelekileyo imalunga ne-3% -10% ye-carrier carrier.
5) Kwinkqubo ye-alkalization kunye ne-etherification, i-cationic okanye i-nonionic surfactants kufuneka yongezwe, kwaye kufuneka ichithwe kwi-carrier carrier ukuze ihambelane ne-colloids.I-surfactants esetyenziswa ngokuqhelekileyo i-lauryl sulfate, i-glycerin Monoester, i-propylene glycol e-fatty acid ester, i-dosage yayo imalunga ne-0.05% -5% ye-carrier carrier.
