Thepa ea Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (CMC) ke polymer e qhibilihang ka metsing, e entsoeng ka selulose.E hlahisoa ke karabelo ea cellulose ka chloroacetic acid le sodium hydroxide.CMC e na le meaho e mengata e fapaneng e e etsang hore e sebelisoe lits'ebetsong tse fapaneng tsa indasteri.Mona ke tse ling tsa thepa ea bohlokoa ea CMC:

1. Solubility: CMC e qhibiliha haholo ka metsing, e etsang hore ho be bonolo ho e tšoara le ho e sebelisa lits'ebetsong tse fapaneng.E ka boela ea qhibiliha ka har'a metsoako e meng ea manyolo, joalo ka ethanol le glycerol, ho latela boemo ba eona ba ho e nkela sebaka.
2. Viscosity: CMC ke polymer e hlakileng haholo e ka etsang li-gel maemong a holimo.The viscosity ea CMC e susumetsoa ke lintlha tse fapaneng, joalo ka tekanyo ea ho fetola, mahloriso, pH, mocheso, le khatello ea electrolyte.
3. Rheology: CMC e bonts'a boits'oaro ba pseudoplastic, ho bolelang hore viscosity ea eona e fokotseha ka sekhahla sa ho kuta.Thepa ena e na le thuso lits'ebetsong moo ho hlokahalang viscosity e phahameng nakong ea ts'ebetso, empa viscosity e tlase e hlokahala nakong ea kopo.
4. Lintho tsa ho etsa lifilimi: CMC e ka etsa lifilimi tse tšesaane, tse tenyetsehang ha li omisitsoe.Lifilimi tsena li na le thepa e ntle ea lithibelo 'me li ka sebelisoa e le liphahlo bakeng sa lits'ebetso tse fapaneng.
5. Botsitso: CMC e tsitsitse ho feta mefuta e mengata ea pH le maemo a mocheso.E boetse e hanyetsana le ho senyeha ha likokoana-hloko, e leng se etsang hore e tšoanelehe ho sebelisoa lijong le lits'ebetsong tsa meriana.
6. Ho boloka metsi: CMC e na le bokhoni ba ho monya le ho boloka metsi, e leng se etsang hore e be thuso lits'ebetsong moo ho boloka metsi ho leng bohlokoa, joalo ka lihlahisoa tsa tlhokomelo ea motho, meriana le lihlahisoa tsa lijo.
7. Emulsion stabilization: CMC e ka sebelisoa ho tsitsisa li-emulsion, tse bohlokoa tlhahisong ea lihlahisoa tse sa tšoaneng, tse kang lipente, li-adhesives le li-coatings.
8. Adhesion: CMC e ka ntlafatsa ho khomarela lits'ebetsong tse fapaneng, joalo ka lirapeng, lipente le likhomaretsi.
9. Thepa ea ho emisoa: CMC e ka ntlafatsa thepa ea ho emisoa ea lihlahisoa tse fapaneng, joalo ka ho emisoa ha li-pigments, liminerale le likaroloana tse ling.

Qetellong, Sodium Carboxymethyl Cellulose (CMC) ke polymer e nang le mekhoa e mengata e fapaneng haholo e bonts'ang mefuta e mengata ea thepa, ho akarelletsa le solubility, viscosity, rheology, botsitso, thepa ea ho etsa lifilimi, ho boloka metsi, ho tsitsisa emulsion, ho khomarela, le thepa ea ho emisa.Thepa ena e etsa hore CMC e be le thuso lits'ebetsong tse fapaneng tsa indasteri, joalo ka lijong, meriana, lihlahisoa tsa tlhokomelo ea motho, le li-detergent, har'a tse ling.
