1.Isingeniso:
I-Sodium carboxymethyl cellulose (NaCMC) iphuma ku-cellulose encibilika emanzini esetshenziswa kabanzi ezimbonini ezinjengokudla, ezemithi, izimonyo, nezindwangu ngenxa yokuqina kwayo okukhethekile, ukuzinza, kanye nezakhiwo zamafilimu. Kodwa-ke, ngesikhathi sokusetshenziswa kwemikhiqizo esekwe ku-NaCMC, kwenzeka izinguquko ezimbalwa zomzimba namakhemikhali, ezinomthelela ekusebenzeni kwayo nokusebenza kwayo.
2.Izinguquko Zomzimba:
Ukunyibilika:
I-NaCMC ibonisa ukunyibilika okuhlukahlukene kuye ngezici ezifana nezinga lokushisa, i-pH, nokuba khona kukasawoti.
Ngokusetshenziswa isikhathi eside, ukunyibilika kwe-NaCMC kungase kwehle ngenxa yezinto ezinjengokuncipha kwesisindo samangqamuzana nokuxhumanisa okuphambanayo, okuthinta i-kinetics yayo yokuhlakazeka nokusebenza ekwakhiweni.
I-Viscosity:
I-Viscosity iyipharamitha ebalulekile elawula ukuziphatha kwe-rheological kanye nokusebenza kwezixazululo ze-NaCMC.
Ngesikhathi sokusetshenziswa, izici ezifana nesilinganiso se-shear, izinga lokushisa, nokuguga zingashintsha i-viscosity yezixazululo ze-NaCMC, zibe nomthelela ekuqinisweni kwayo nasekuzinziseni izakhiwo ezisetshenziswayo ezifana nokudla kanye nokwakhiwa kwemithi.
Isisindo se-Molecular:
I-NaCMC ingase ibe nokuwohloka ngesikhathi sokusetshenziswa, okuholela ekwehleni kwesisindo samangqamuzana.
Lokhu kuncipha kwesisindo samangqamuzana kungathonya izakhiwo ezahlukahlukene, kufaka phakathi i-viscosity, ukunyibilika, kanye nekhono lokwenza ifilimu, ngaleyo ndlela kuthinte ukusebenza okuphelele kwemikhiqizo esekwe ku-NaCMC.
3.Izinguquko Zamakhemikhali:
Ukuxhumanisa:
Ukuxhumanisa ama-molecule e-NaCMC kungenzeka ngesikhathi sokusetshenziswa, ikakhulukazi ezinhlelweni ezibandakanya ukuchayeka kuma-divalent cations noma ama-agent axhumanisa.
I-Cross-linking ishintsha ukwakheka kwenethiwekhi ye-polymer, okuthinta izakhiwo ezifana nokuncibilika, i-viscosity, nokuziphatha kwe-gelation, ngaleyo ndlela kube nomthelela ekusebenzeni kwe-NaCMC ezinhlelweni ezihlukene.
Ukulungiswa Kwesakhiwo:
Ukuguqulwa kwamakhemikhali, njengedigri ye-carboxymethylation kanye nephethini yokufaka esikhundleni, kungase kube nezinguquko ngesikhathi sokusetshenziswa, kuthinte ukwakheka nezakhiwo ze-NaCMC.
Ukuguqulwa kwesakhiwo kuthonya izici ezifana nokugcinwa kwamanzi, amandla okubopha, nokunamathela, ngaleyo ndlela kuthinte ukusebenza kwe-NaCMC ezinhlelweni ezifana nezithasiselo zokudla kanye nokwakheka kwemithi.
4. Imithelela Kuzicelo:
Imboni Yokudla:
Izinguquko ezimpahleni ezibonakalayo namakhemikhali e-NaCMC ngesikhathi sokusetshenziswa zingathonya ukusebenza kwayo njenge-thickener, stabilizer, noma emulsifier emikhiqizweni eyahlukene yokudla.
Ukuqonda lezi zinguquko kubalulekile ekugcineni ikhwalithi yomkhiqizo kanye nokuvumelana ekwakhiweni kokudla.
Imboni Yezemithi:
I-NaCMC isetshenziswa kabanzi ekwakhiweni kwemithi yezakhiwo zayo ezihlanganisayo, ezihlukanisayo, nezishintsha i-viscosity.
Ukushintsha kwezinto ezibonakalayo namakhemikhali e-NaCMC ngesikhathi sokusetshenziswa kungase kube nomthelela ekusebenzeni kwayo ezinhlelweni zokulethwa kwezidakamizwa, ukwakhiwa kokukhishwa okulawulwayo, kanye nokusetshenziswa kwezihloko.
5.Imboni Yokuthunga:
I-NaCMC isetshenziswa embonini yendwangu ukukala, ukuphrinta, nokuqeda izinhlelo zokusebenza.
Izinguquko ezakhiweni ezifana ne-viscosity nesisindo samangqamuzana ngesikhathi sokusetshenziswa zingathinta ukusebenza kahle kwama-agent asekelwe ku-NaCMC noma ama-paste okuphrinta, okudinge ukulungiswa ekubunjweni nasekucubunguleni amapharamitha.
I-Sodium carboxymethyl cellulose (NaCMC) iba nezinguquko ezibalulekile zomzimba namakhemikhali ngesikhathi sokusetshenziswa, okunomthelela ekuncibilikeni kwayo, i-viscosity, isisindo samangqamuzana, kanye nezakhiwo zayo. Lezi zinguquko zinemithelela ejulile ekusebenzeni nasekusebenzeni kwemikhiqizo esekelwe ku-NaCMC kuzo zonke izimboni ezihlukahlukene, okuhlanganisa ukudla, ezamakhemisi, nezindwangu. Ukuqonda lezi zinguquko kubalulekile ekuthuthukiseni ukwakheka, ukucutshungulwa, kanye nokusetshenziswa kwe-NaCMC, ngaleyo ndlela kuqinisekiswe ukusebenza kahle kanye nekhwalithi yemikhiqizo yokugcina. Ucwaningo olwengeziwe lufanelekile ukuhlola amasu okunciphisa izinguquko ezingathandeki kanye nokuthuthukisa ukusebenza kwe-NaCMC ezinhlelweni ezihlukahlukene.
