Polyanionic cellulose (PAC) le sodium carboxymethyl cellulose (CMC) ke mefuta e 'meli ea li-cellulose ethers tse nang le sebopeho sa lik'hemik'hale le thepa e tšoanang, empa li fapana ka likarolo tse ling tsa bohlokoa.

PAC ke ether ea cellulose e qhibilihang ka metsing e nang le boemo bo phahameng ba ho fetola, ho bolelang hore lihlopha tse ngata tsa carboxymethyl li khomaretsoe mokokotlong oa cellulose. PAC e atisa ho sebelisoa e le viscosifier le se fokotsang tahlehelo ea mokelikeli marong a chekang oli ka lebaka la ho boloka metsi hantle, botsitso le thepa ea eona e teteaneng.

Ka lehlakoreng le leng, CMC ke ether ea cellulose e qhibilihang ka metsing e sebelisoang haholo e le sekontiri, se tlamang, le se tsitsitseng liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, litlolo le tlhahiso ea pampiri. CMC e hlahisoa ke karabelo ea cellulose ka monochloroacetic acid ho hlahisa lihlopha tsa carboxymethyl mokokotlong oa cellulose. Tekanyo ea ho kenya sebaka sa CMC e tlase ho feta ea PAC, empa e ntse e fana ka mokhoa o motle oa ho boloka metsi, botsitso le thepa e teteaneng.

Leha ka bobeli PAC le CMC e le li-cellulose ethers tse nang le thepa e tšoanang, li fapana ka likarolo tse ling tsa bohlokoa. Mohlala, PAC hangata e sebelisoa indastering ea ho cheka oli ka lebaka la boemo ba eona bo phahameng ba ho fetola le thepa e ntle ea phokotso ea mokelikeli, athe CMC e sebelisoa liindastering tse fapaneng ka lebaka la boemo ba eona bo tlase ba ho kenya sebaka le ho feto-fetoha ha maemo lits'ebetsong tse fapaneng.

Ka kakaretso, PAC le CMC ke li-ether tsa bohlokoa tsa cellulose tse nang le thepa le lits'ebetso tse ikhethang. Le ha PAC e sebelisoa haholo indastering ea ho cheka oli, CMC e na le mefuta e mengata ea lits'ebetso liindastering tse fapaneng ka lebaka la ho feto-fetoha ha eona le boemo bo tlase ba ho nka sebaka.
