Ukuhlola i-viscosity ye-sodium carboxymethyl cellulose (CMC) yezinga lokudla kubalulekile ukuze kuqinisekiswe ukusebenza kwayo nokusebenza ezinhlelweni ezihlukahlukene zokudla. Izilinganiso ze-viscosity zisiza abakhiqizi banqume amandla okujiya nokuzinzisa ezixazululo ze-CMC, ezibalulekile ukuze kuzuzwe izici ezifiselekayo zomkhiqizo ezifana nokuthungwa, ukuzwakala komlomo, nokuzinza. Nawu umhlahlandlela ophelele wendlela yokuhlola ye-sodium CMC viscosity yebanga lokudla:

1. Isimiso:

• I-viscosity isilinganiso sokumelana koketshezi nokugeleza. Esimeni sezixazululo ze-CMC, i-viscosity ithonywa izinto ezifana nokugxilwa kwe-polymer, i-degree of substitution (DS), isisindo samangqamuzana, i-pH, izinga lokushisa, nezinga lokugunda.
• I-viscosity yezixazululo ze-CMC ngokuvamile ikalwa kusetshenziswa i-viscometer, esebenzisa ingcindezi ye-shear oketshezini futhi ikala ukuwohloka okuwumphumela noma izinga lokugeleza.

2. Izisetshenziswa nama-reagents:

• Isampula ye-sodium carboxymethyl cellulose (CMC) yezinga lokudla.
• Amanzi acwecwe.
• I-Viscometer (isb, i-viscometer yase-Brookfield, i-viscometer ejikelezayo noma ye-capillary).
• I-spindle ifanele ububanzi be-viscosity besampula.
• Ukugeza ngamanzi alawulwa izinga lokushisa noma igumbi le-thermostatic.
• I-stirrer noma i-stirrer magnetic.
• Ama-beakers noma izinkomishi zesampula.
• Isitophuwashi noma isibali sikhathi.

3. Inqubo:

1. Ukulungiselela Isampula:
   • Lungiselela uchungechunge lwezixazululo ze-CMC ezinokugxila okuhlukile (isb, 0.5%, 1%, 2%, 3%) emanzini acwecwe. Sebenzisa ibhalansi ukuze ukale inani elifanele lempushana ye-CMC futhi uyengeze kancane kancane emanzini ngokunyakazisa ukuqinisekisa ukuhlakazeka okuphelele.
   • Vumela izixazululo ze-CMC ukuthi zifake amanzi futhi zilingane isikhathi esanele (isb, amahora angama-24) ukuze uqinisekise ukugeleza kwamanzi okufanayo kanye nokuzinza.
2. Ukusethwa Kwensimbi:
   • Linganisa i-viscometer ngokwemiyalelo yomkhiqizi usebenzisa uketshezi olujwayelekile lwereferensi ye-viscosity.
   • Setha i-viscometer ebangeni elifanele lejubane noma izinga lokugunda ukuze uthole i-viscosity elindelekile yezixazululo ze-CMC.
   • Shisisa kuqala i-viscometer kanye ne-spindle kuzinga lokushisa elifiswayo lokuhlola usebenzisa ibhavu lamanzi elilawulwa izinga lokushisa noma igumbi le-thermostatic.
3. Isilinganiso:
   • Gcwalisa inkomishi yesampula noma ibhika ngesisombululo se-CMC okufanele sihlolwe, uqinisekise ukuthi i-spindle icwiliswe ngokuphelele kusampula.
   • Yehlisa i-spindle kusampula, uqaphele ukugwema ukwethula amabhamuza omoya.
   • Qala i-viscometer futhi uvumele i-spindle ukuthi ijikeleze ngesivinini esishiwo noma izinga lokugunda isikhathi esinqunyiwe (isb., iminithi elingu-1) ukuze ufinyelele esimweni sokuzinzile.
   • Qopha ukufundwa kwe-viscosity okuvezwe ku-viscometer. Phinda ukulinganisa kwesixazululo ngasinye se-CMC futhi ngamanani ahlukene okugunda uma kunesidingo.
4. Ukuhlaziywa Kwedatha:
   • Hlela amanani e-viscosity ngokumelene nokugxila kwe-CMC noma izinga lokugunda ukuze ukhiqize amajika e-viscosity.
   • Bala amanani abonakalayo e-viscosity ngamanani athile okugunda noma ukugxila ukuze uqhathanise nokuhlaziya.
   • Nquma ukuziphatha kwe-rheological kwezixazululo ze-CMC (isb, i-Newtonian, i-pseudoplastic, i-thixotropic) ngokusekelwe ekubunjweni kwamajika e-viscosity kanye nomthelela wezinga le-shear ku-viscosity.
5. Ukutolika:
   • Amanani e-viscosity aphezulu akhombisa ukumelana okukhulu nokugeleza kanye nezakhiwo eziqina kakhulu zesixazululo se-CMC.
   • Ukuziphatha kwe-viscosity yezixazululo ze-CMC kungahluka kuye ngezinto ezifana nokugxilisa ingqondo, izinga lokushisa, i-pH, nezinga lokugunda. Ukuqonda lezi zici kubalulekile ekwenzeni ngcono ukusebenza kwe-CMC ezinhlelweni ezithile zokudla.

4. Okucatshangwayo:

• Qinisekisa ukulinganiswa okufanele nokugcinwa kwe-viscometer ukuze uthole izilinganiso ezinembile nezithembekile.
• Lawula izimo zokuhlola (isb., izinga lokushisa, izinga lokugunda) ukuze unciphise ukuhlukahluka nokuqinisekisa ukuphindaphindeka kwemiphumela.
• Qinisekisa indlela usebenzisa izilinganiso zereferensi noma ukuhlaziya okuqhathanisayo nezinye izindlela eziqinisekisiwe.
• Yenza izilinganiso ze-viscosity ezindaweni eziningi ngokuhambisana nezimo zokucubungula noma zokulondoloza ukuze uhlole ukuzinza nokufaneleka kwezinhlelo ezihlosiwe.

Ngokulandela le ndlela yokuhlola, i-viscosity yezixazululo ze-sodium carboxymethyl cellulose (CMC) yezinga lokudla inganqunywa ngokunembile, inikeze ulwazi olubalulekile lokwakheka, ukulawulwa kwekhwalithi, kanye nokwenza kahle kwenqubo embonini yokudla.
