Litšobotsi tsa CMC

Sodium carboxymethyl cellulose (CMC) ke polima e qhibilihang ka metsing e tsoang ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Mona ke lintlha tse ling tsa bohlokoa tsa CMC:

  1. Ho qhibiliha ha metsi: CMC e qhibiliha haholo metsing le litharollong tse ling tse nang le metsi, e etsa litharollo tse hlakileng kapa tse senyehileng hanyane.
  2. Viscosity: CMC e ka theha litharollo tse hlakileng haholo, ho latela boemo ba sebaka, boima ba limolek'hule le mahloriso. Hangata e sebelisoa e le mofetoleli oa thickener le rheology lits'ebetsong tse fapaneng.
  3. pH botsitso: CMC e tsitsitse ho feta mefuta e mengata ea pH ea boleng, hangata ho tloha pH 2 ho ea ho 12. E ka boloka thepa ea eona e teteaneng le e tsitsitseng maemong a asiti, a sa nke lehlakore le a alkaline.
  4. Kutloelo-bohloko ea Ionic: CMC e ka angoa ke matla a ionic a tharollo. E ka etsa li-gel tse fokolang kapa ea lahleheloa ke thepa ea eona e teteaneng maemong a letsoai le phahameng.
  5. Hygroscopicity: CMC ke hygroscopic, ho bolelang hore e ka monya mongobo o tsoang tikolohong. Thepa ena e ka ama ts'ebetso ea eona, polokelo le ts'ebetso ea eona lits'ebetsong tse itseng.
  6. Thepa ea ho etsa lifilimi: CMC e ka etsa lifilimi tse tenyetsehang le tse pepeneneng ha e omella. E ka sebelisoa e le thepa ea ho roala kapa e kopanyang lits'ebetsong tse fapaneng.
  7. Biodegradability: CMC e ka senyeha habonolo ebile e na le botsoalle ba tikoloho. E ka senyeha ke li-enzyme tse hlahisoang ke likokoana-hloko mobung kapa metsing.

Ka kakaretso, sodium carboxymethyl cellulose ke polymer e feto-fetohang e nang le mefuta e mengata e etsang hore e sebelisoe lits'ebetsong tse fapaneng, joalo ka lijo, meriana, tlhokomelo ea motho le lihlahisoa tsa indasteri.
