Sodium carboxymethyl cellulose (CMC) ke derivative e sebelisoang haholo ea cellulose e nang le lits'ebetso tse fapaneng liindastering tse fapaneng.Bohloeki ba CMC bo bapala karolo ea bohlokoa ho eleheng katleho le ts'ebetso ea eona lits'ebetsong tse fapaneng.Pampiri ena e ikemiselitse ho fana ka kakaretso ea mekhoa e fapaneng e sebelisoang ho ahlola bohloeki ba sodium carboxymethyl cellulose.Mekhoa ea ho sekaseka joalo ka tlhahlobo ea degree of substitution (DS), tlhahlobo ea viscosity, tlhahlobo ea mantlha, boikemisetso ba boemo ba mongobo, le tlhahlobo ea litšila li tšohloa ka botlalo.Ka ho sebelisa mekhoa ena, bahlahisi, bafuputsi le basebelisi ba ka lekola boleng le ts'epahalo ea lihlahisoa tsa CMC, ba ba nolofalletsa ho etsa liqeto tse nang le tsebo ho latela maemo a batloang a bohloeki.
Sodium carboxymethyl cellulose (CMC) ke derivative ea cellulose e fumanoang ka phetoho ea lik'hemik'hale ea selulose, haholo-holo e nkiloeng ho makhasi a lehong kapa k'hothone.CMC e fumana lits'ebetso tse pharalletseng liindastering tse kang lijo, meriana, litlolo, masela le ho cheka oli ka lebaka la thepa ea eona e ikhethang.Leha ho le joalo, bohloeki ba CMC bo susumetsa haholo ts'ebetso ea eona le ho tšoaneleha bakeng sa lits'ebetso tse ikhethileng.Ka hona, mekhoa e fapaneng ea tlhahlobo e ntlafalitsoe ho ahlola bohloeki ba CMC ka nepo.
Tlhahlobo ea Degree of Substitution (DS):
Tekanyo ea ho kenya sebaka ke paramente ea bohlokoa e sebelisoang ho lekola bohloeki ba CMC.E emela palo e tloaelehileng ea lihlopha tsa carboxymethyl ka yuniti ea cellulose ka molek'hule ea CMC.Mekhoa e kang ea nuclear magnetic resonance (NMR) spectroscopy le mekhoa ea titration e ka sebelisoa ho fumana boleng ba DS.Litekanyetso tse phahameng tsa DS hangata li bontša bohloeki bo phahameng.Ho bapisa boleng ba DS ba sampole ea CMC le litekanyetso tsa indasteri kapa litlhaloso tsa moetsi ho lumella tlhahlobo ea bohloeki ba eona.
Teko ea Viscosity:
Tekanyo ea viscosity ke mokhoa o mong oa bohlokoa oa ho lekola bohloeki ba CMC.Viscosity e amana haufi-ufi le thepa e teteaneng le e tsitsitseng ea CMC.Limaraka tse fapaneng tsa CMC li na le mefuta e fapaneng ea viscosity, 'me ho kheloha ho tloha mefuteng ena ho ka bontša litšila kapa phapang ea mokhoa oa tlhahiso.Li-viscometers kapa li-rheometers li sebelisoa hangata ho lekanya viscosity ea tharollo ea CMC, 'me boleng bo fumanoeng bo ka bapisoa le mofuta o boletsoeng oa viscosity ho ahlola bohloeki ba CMC.
Elemental Analysis:
Tlhahlobo ea mantlha e fana ka leseli la bohlokoa mabapi le sebopeho sa mantlha sa CMC, se thusang ho tsebahatsa litšila kapa tšilafalo.Mekhoa e kang plasma optical emission spectrometry (ICP-OES) kapa matla-dispersive X-ray spectroscopy (EDS) e ka sebelisoa ho fumana sebopeho sa mantlha sa lisampole tsa CMC.Phapang efe kapa efe e kholo ho tsoa ho tekanyo e lebelletsoeng ea motheo e ka bonts'a litšila kapa lintho tse tsoang kantle ho naha, e fana ka maikutlo a ho sekisetsa bohloeki.
Boikemisetso ba Boemo ba Mongobo:
Mongobo oa CMC ke parameter ea bohlokoa e lokelang ho nahanoa ha ho hlahlojoa bohloeki ba eona.Mongobo o feteletseng o ka lebisa ho clumping, ho fokotseha ha solubility, le ts'ebetso e senyehileng.Mekhoa e kang ea Karl Fischer titration kapa thermogravimetric analysis (TGA) e ka sebelisoa ho fumana boemo ba mongobo ba lisampole tsa CMC.Ho bapisa mongobo o lekantsoeng le meeli e boletsoeng ho nolofalletsa ho ahlola bohloeki le boleng ba sehlahisoa sa CMC.
Tlhahlobo ea Tšilafalo:
Tlhahlobo ea ho se hloeke e kenyelletsa ho hlahloba boteng ba litšila, lik'hemik'hale tse setseng, kapa lihlahisoa tse sa batleheng ho CMC.Mekhoa e joalo ka mokelikeli o sebetsang hantle haholo oa chromatography (HPLC) kapa khase chromatography-mass spectrometry (GC-MS) e ka sebelisoa ho tseba le ho lekanya litšila.Ka ho bapisa lintlha tse sa hloekang tsa lisampole tsa CMC le meeli e amohelehang kapa maemo a indasteri, ho hloeka ha CMC ho ka hlahlojoa.
Ho ahlola ka nepo bohloeki ba sodium carboxymethyl cellulose (CMC) ho bohlokoa bakeng sa ho netefatsa katleho le ts'epahalo ea eona lits'ebetsong tse fapaneng.Mekhoa ea tlhahlobo e joalo ka tekanyo ea tlhahlobo ea sebaka, tlhahlobo ea viscosity, tlhahlobo ea mantlha, boikemisetso ba boleng ba mongobo, le tlhahlobo ea litšila li fana ka leseli la bohlokoa mabapi le bohloeki ba CMC.Baetsi, bafuputsi le basebelisi ba ka sebelisa mekhoa ena ho etsa liqeto tse nepahetseng le ho khetha lihlahisoa tsa boleng bo holimo tsa CMC tse fihlelang litlhoko tsa bona tse ikhethileng.Lintlafatso tse ling tsa mekhoa ea tlhahlobo li tla tsoela pele ho ntlafatsa bokhoni ba rona ba ho lekola le ho netefatsa bohloeki ba CMC nakong e tlang.
