Kuthonya izinto ku-sodium carboxymethylcelcelcelcelcese

I-viscosity yeSodium Carboxymethylcelcelcelcelcelcel (CMC) ingathonywa yizici eziningana. Nazi ezinye zezinto ezibalulekile ezithinta ukubonakala kwezixazululo ze-CMC:

1. Ukuhlushwa: I-viscosity yezixazululo ze-CMC ngokuvamile inyuka ngokuhlushwa okwandayo. Ukugxila okuphezulu komphumela we-CMC kumaketanga amaningi we-polymer kwikhambi, okuholela ekunikezelweni okukhulu kwamangqamuzana kanye nokubonakala okuphezulu. Kodwa-ke, imvamisa kunomkhawulo wokuvuleka ukwanda kokugxila okuphezulu ngenxa yezici ezinjenge-Rheology yesisombululo kanye nokuxhumana kwe-polymer-solvent.
2. I-degree yokufaka esikhundleni (DS): Izinga lokufaka esikhundleni lisho inani eliphakathi lamaqembu e-carboxymethyl ngamunye uphiko lwe-glucose ku-cellulose chain. I-CMC ene-DS ephakeme ivame ukuba ne-viscosity ephezulu ngoba inamaqembu athe xaxa, agqugquzela ukusebenzisana okunamandla okwenzeka kanye nokuphikiswa okukhulu ukugeleza.
3. Isisindo samangqamuzana: Isisindo samangqamuzana se-CMC singathonya ukubonakala kwaso. I-Molecular Weight CMC ephakeme ngokujwayelekile iholela ezixazululweni eziphakeme ze-viscosity ngenxa yokukhuphuka kwamaketanga namaketanga amade we-polymer. Kodwa-ke, i-CMC ephezulu kakhulu ye-molecular i-CMC nayo ingahle iholele ekuvuselelekeni kwesixazululo ngaphandle kokwanda okulinganayo kokusebenza kahle.
4. Ukushisa: izinga lokushisa linomthelela omkhulu ekubonakaleni kwezixazululo ze-CMC. Ngokuvamile, ukuhlakanipha kuyancipha njengoba izinga lokushisa likhuphuka ngenxa yokuncishiswa kwe-polymer-solvent kokusebenzisana kanye nokunyusa ama-molecular molecular. Kodwa-ke, umphumela wezinga lokushisa ku-viscosity ungahluka ngokuya ngezinto ezifana nokuhlushwa kwe-polymer, isisindo samangqamuzana, nesixazululo PH.
5. I-PH: I-PH yesisombululo se-CMC ingathinta ukubonakala kwayo ngenxa yezinguquko ku-polymer ionization kanye ne-conformation. I-CMC ngokuvamile i-viscous ngokwengeziwe kumanani we-PH aphezulu ngoba amaqembu e-carboxymethyl ama-Ionosed, okuholela ekubuyiselweni kwe-elektrostiki okunamandla phakathi kwamaketanga we-polymer. Kodwa-ke, izimo ze-EXTRECT CH zingaholela ezinguquko ku-polymer solibity kanye ne-conformation, ezingathinta i-viscosity ngendlela ehlukile kunebanga elithile le-CMC nokwakhiwa.
6. Okuqukethwe usawoti: Ukuba khona kukasawoti kukhambi kungathonya ukubonakala kwezixazululo ze-CMC ngemiphumela ekuxhumaneni nge-polymer-solvent kanye nokusebenzisana kwe-ion-polymer. Kwezinye izimo, ukungezwa kosawoti kungakhuphula ukubonakala ngokuhlola izimpungushe ze-electrostatic phakathi kwamaketanga we-polymer, ngenkathi kwezinye izimo, kunganciphisa ukubonwa okuhlangene ngokuphazamisa ukusebenzisana kwe-polymer-solvent kanye nokukhuthaza ukuhlanganiswa kwe-polyment.
7. Isilinganiso se-Shear: I-viscosity yezixazululo ze-CMC nayo ingancika ekutheni izinga le-Shear noma isilinganiso lapho kufakwa khona ingcindezi kwikhambi. Izixazululo ze-CMC zivame ukukhombisa ukusebenza okunciphisayo kokuncipha, lapho ukubonakala kuncipha ngezinga elikhulayo le-shear ngenxa yokuqondanisa nokuqondiswa kwamaketanga we-polymer eceleni kwendlela yokugeleza. Ubungako bokuncipha kwe-shear bungahluka ngokuya ngezinto ezifana nokuhlushwa kwe-polymer, isisindo se-molecular, nesixazululo ph.

I-viscosity ye-sodium carboxylselcelcelcelsose solutions ithonywa ukuhlanganiswa kwezinto kufaka phakathi ukugxila, isilinganiso sokufakwa esikhundleni, isisindo se-molecular, izinga lokushisa, i-pH, okuqukethwe usawoti. Ukuqonda lezi zinto kubalulekile ukwenza kahle ukubonakala kwezixazululo ze-CMC ukuthola izinhlelo ezithile ezisetshenziselwa izimboni ezinjengokudla, amakhambi, izimonyo, kanye nokunakekelwa komuntu siqu.
