The dispersibility nke carboxymethyl cellulose bụ na ngwaahịa ga-decomated na mmiri, otú dispersibility nke ngwaahịa aghọwokwa ụzọ ikpe ikpe ya arụmọrụ. Ka anyị mụtakwuo maka ya:
1) A na-agbakwunye mmiri ụfọdụ na usoro mgbasa ozi enwetara, nke nwere ike imeziwanye mgbasa nke colloidal particles na mmiri, ọ dịkwa mkpa iji hụ na mmiri agbakwunyere enweghị ike igbari colloid.
2) Ọ dị mkpa ịkwasa ihe ndị na-emepụta ihe na-eme ka mmiri na-ebu mmiri na-ebu mmiri nke na-adịghị mma na mmiri, nke na-adịghị edozi na gels mmiri ma ọ bụ na-enweghị mmiri, ma ọ ga-abụrịrị ibu karịa olu nke colloidal ahụ ka ha wee nwee ike gbasaa kpamkpam. . bụ mmanya monohydric dị ka methanol na ethanol, ethylene glycol, acetone, wdg.
3) Ekwesịrị ịtinye nnu na-agbaze mmiri na mmiri na-ebu ya, mana nnu enweghị ike imeghachi ya na colloid. Isi ọrụ ya bụ igbochi gel na-agbaze mmiri ka ọ ghara ịmepụta mado ma ọ bụ coagulating na mmiri ozuzo mgbe ọ na-ezu ike. A na-ejikarị sodium chloride na ihe ndị ọzọ.
4) Ọ dị mkpa ịgbakwunye onye na-akwụsịtụ na mmiri na-ebu ibu iji gbochie ihe omume nke ọdịda gel. Onye na-ahụ maka nkwụsịtụ nwere ike ịbụ glycerin, hydroxypropyl methylcellulose, wdg. Onye na-egbochi ya kwesịrị ịdị na-agbaze na onye na-ebu mmiri mmiri ma kwekọọ na colloid. Maka carboxymethyl cellulose, ọ bụrụ na ejiri glycerol mee ihe dị ka onye na-akwụsịtụ, usoro ọgwụgwọ a na-emebu bụ ihe dịka 3%-10% nke mmiri mmiri na-ebu.
5) Na usoro nke alkalization na etherification, a ga-agbakwunye cationic ma ọ bụ nonionic surfactants, na a ga-agbaze n'ime ụgbọ mmiri na-ebu mmiri ka ọ kwekọọ na colloids. Surfactants ndị a na-ejikarị eme ihe bụ lauryl sulfate, glycerin Monoester, propylene glycol fatty acid ester, usoro ọgwụgwọ ya bụ ihe dịka 0.05%-5% nke mmiri na-ebu.
