Ho etsa tlhahlobo ea viscosity ea sodium carboxymethyl cellulose (CMC) ea boemo ba lijo ho bohlokoa bakeng sa ho netefatsa ts'ebetso le ts'ebetso ea eona lits'ebetsong tse fapaneng tsa lijo. Litekanyo tsa viscosity li thusa bahlahisi ho tseba bokhoni bo matla le bo tsitsitseng ba tharollo ea CMC, e leng bohlokoa bakeng sa ho fihlela litšobotsi tse lakatsehang tsa sehlahisoa joalo ka sebopeho, molomo le botsitso. Mona ke tataiso e felletseng ea mokhoa oa tlhahlobo oa viscosity ea sodium CMC ea boemo ba lijo:

1. Molao-motheo:

• Viscosity ke tekanyo ea hore mokelikeli o hana ho phalla. Tabeng ea tharollo ea CMC, viscosity e susumetsoa ke lintlha tse kang polymer concentration, degree of substitution (DS), boima ba limolek'hule, pH, mocheso, le sekhahla sa ho kuta.
• Viscosity ea tharollo ea CMC hangata e lekanyetsoa ho sebelisoa viscometer, e sebelisang khatello ea maikutlo ho mokelikeli le ho lekanya ho senyeha ho bakoang kapa sekhahla sa phallo.

2. Lisebelisoa le Lisebelisoa:

• Mohlala oa lijo tsa sodium carboxymethyl cellulose (CMC).
• Metsi a hloekisitsoeng.
• Viscometer (mohlala, Brookfield viscometer, rotational kapa capillary viscometer).
• Spindle e loketseng mofuta oa viscosity oa sampole.
• Bate ea metsi e laoloang ke mocheso kapa kamore ea thermostatic.
• Sehlahisoa kapa matla a khoheli.
• Li-beakers kapa likopi tsa mohlala.
• Stopwatch kapa sebali sa nako.

3. Mokhoa:

1. Tokiso ea Mohlala:
   • Lokisetsa letoto la tharollo ea CMC e nang le likhakanyo tse fapaneng (mohlala, 0.5%, 1%, 2%, 3%) metsing a hloekisitsoeng. Sebelisa ho leka-lekana ho lekanya palo e loketseng ea phofo ea CMC le ho e eketsa butle-butle metsing ka ho sisinyeha ho etsa bonnete ba ho hasana ka ho feletseng.
   • Lumella litharollo tsa CMC ho fana ka metsi le ho leka-lekanya nako e lekaneng (mohlala, lihora tse 24) ho etsa bonnete ba hore ho na le metsi a tšoanang le botsitso.
2. Tlhophiso ea Lisebelisoa:
   • Lekanya viscometer ho latela litaelo tsa moetsi u sebelisa mokelikeli o tloaelehileng oa viscosity.
   • Beha viscometer ho lebelo le loketseng kapa lebelo la sekhahla bakeng sa viscosity e lebelletsoeng ea tharollo ea CMC.
   • Preheat viscometer le spindle ho mocheso o lakatsehang oa teko o sebelisa bate ea metsi e laoloang ke mocheso kapa kamore ea thermostatic.
3. Tekanyo:
   • Tlatsa kopi ea mohlala kapa beaker ka tharollo ea CMC e lokelang ho lekoa, ho netefatsa hore spindle e qoelisoa ka botlalo sampoleng.
   • Theola seluloana ka har'a sampole, u hlokomele ho qoba ho hlahisa libubble tsa moea.
   • Qala viscometer 'me u lumelle spindle ho potoloha ka lebelo le boletsoeng kapa sekhahla sa ho kuta bakeng sa nako e reriloeng esale pele (mohlala, motsotso o le mong) ho fihlela boemo bo tsitsitseng.
   • Rekota 'malo oa viscosity o bontšitsoeng ho viscometer. Pheta tekanyo ea tharollo ea CMC ka 'ngoe le ka litekanyetso tse fapaneng tsa ho kuta ha ho hlokahala.
4. Tlhahlobo ea Lintlha:
   • Rala boleng ba viscosity khahlano le khatello ea CMC kapa sekhahla sa ho kuta ho hlahisa li-curve tsa viscosity.
   • Bala boleng bo bonahalang ba viscosity ka litekanyetso tse khethehileng tsa ho kuta kapa likhakanyo bakeng sa ho bapisa le ho hlahloba.
   • Etsa qeto ea boitšoaro ba rheological ea tharollo ea CMC (mohlala, Newtonian, pseudoplastic, thixotropic) ho latela sebōpeho sa li-curve tsa viscosity le phello ea sekhahla sa ho kuta ho viscosity.
5. Tlhaloso:
   • Maemo a phahameng a viscosity a bonts'a khanyetso e kholo ea phallo le thepa e matla ea ho tenya ea tharollo ea CMC.
   • Boitšoaro ba viscosity ea litharollo tsa CMC bo ka fapana ho latela lintlha tse kang khatello, mocheso, pH le sekhahla sa ho kuta. Ho utloisisa lintlha tsena ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea CMC lits'ebetsong tse ikhethileng tsa lijo.

4. Maikutlo:

• Etsa bonnete ba ho lekanya hantle le tlhokomelo ea viscometer bakeng sa litekanyo tse nepahetseng le tse ka tšeptjoang.
• Laola maemo a teko (mohlala, mocheso, sekhahla sa ho kuta) ho fokotsa ho feto-fetoha le ho netefatsa hore liphetho li fumaneha hape.
• Netefatsa mokhoa o sebelisa litekanyetso tsa litšupiso kapa tlhahlobo ea papiso le mekhoa e meng e netefalitsoeng.
• Etsa litekanyo tsa viscosity lintlheng tse ngata hammoho le maemo a ho sebetsa kapa a polokelo ho lekola botsitso le ho tšoaneleha bakeng sa lits'ebetso tse reriloeng.

Ka ho latela mokhoa ona oa tlhahlobo, viscosity ea tharollo ea sodium carboxymethyl cellulose (CMC) ea boemo ba lijo e ka khethoa ka nepo, e fana ka tlhaiso-leseling ea bohlokoa bakeng sa tlhahiso, taolo ea boleng, le ts'ebetso ea ts'ebetso indastering ea lijo.
