Thepa ea Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (NaCMC) ke polima e qhibilihang ka metsing e nkiloeng ho selulose. E na le lisebelisoa tse fapaneng tsa 'mele le tsa lik'hemik'hale tse e etsang hore e sebelisoe mefuteng e mengata ea liindasteri. Mona ke tse ling tsa thepa ea bohlokoa ea NaCMC:

  1. Ho qhibiliha ha metsi: NaCMC e qhibiliha haholo ka metsing 'me e ka etsa tharollo e hlakileng le e hlakileng.
  2. Rheology: NaCMC e bonts'a boitšoaro ba ho kuta, ho bolelang hore viscosity ea eona ea fokotseha ha sekhahla sa ho kuta se ntse se eketseha. Thepa ena e etsa hore e be ea bohlokoa e le motenya le stabilizer lits'ebetsong tse ngata.
  3. pH botsitso: NaCMC e tsitsitse ho feta mefuta e mengata ea pH ea boleng, ho tloha ho acidic ho ea ho alkaline.
  4. Matla a Ionic: NaCMC e tsotella matla a ionic mme e ka sebelisoa ho tiisa le ho tsitsisa tharollo e nang le li-ion tse fapaneng.
  5. Thermal botsitso: NaCMC e tsitsitse mochesong o phahameng mme e ka sebelisoa lits'ebetsong tse hlokang ho hanyetsa mocheso.
  6. Bokhoni ba ho etsa lifilimi: NaCMC e ka etsa filimi e tšesaane, e bonaletsang, ebile e tenyetseha ha e omisitsoe. Thepa ena e etsa hore e be ea bohlokoa lits'ebetsong tse kang liphahlo, lifilimi le likhomaretsi.
  7. Biodegradability: NaCMC ke biodegradable polymer, e bolelang hore e ka aroloa ke likokoana-hloko tse tikolohong.

Ka kakaretso, NaCMC e na le motsoako o ikhethileng oa thepa e e etsang hore e be molemo lits'ebetsong tse fapaneng, ho kenyeletsoa lijo, meriana, litlolo, le lits'ebetso tse ngata tsa indasteri. Bokhoni ba eona ba ho etsa litharollo tsa viscous, botsitso ba pH, le bokhoni ba eona ba ho etsa lifilimi bo etsa hore e be motsoako oa bohlokoa lihlahisoa tse ngata.
