Umthelela we-DS ku-carboxymethyl cellulose Ikhwalithi

I-Degree of Substitution (DS) iyipharamitha ebalulekile enethonya ngokuphawulekayo izinga nokusebenza kweCarboxymethyl Cellulose (CMC). I-DS ibhekisela enanini eliyisilinganiso lamaqembu e-carboxymethyl afakwe endaweni yeyunithi ngayinye ye-anhydroglucose yomgogodla we-cellulose. Inani le-DS lithinta izici ezihlukahlukene ze-CMC, okuhlanganisa ukuncibilika kwayo, i-viscosity, amandla okugcina amanzi, nokuziphatha kwe-rheological. Nansi indlela i-DS enomthelela ngayo kwikhwalithi ye-CMC:

1. Ukunyibilika:

• I-DS ephansi: I-CMC ene-DS ephansi ijwayele ukuncibilika kancane emanzini ngenxa yamaqembu ambalwa e-carboxymethyl atholakalayo e-ionization. Lokhu kungase kubangele amazinga okuncibilika kancane kanye nezikhathi ezinde zokugeleza kwamanzi.
• I-DS ephezulu: I-CMC ene-DS ephezulu incibilika kakhulu emanzini, njengoba inani elikhulayo lamaqembu e-carboxymethyl lithuthukisa i-ionization kanye nokuhlakazeka kwamaketanga e-polymer. Lokhu kuholela ekuqedweni ngokushesha kanye nezakhiwo ezithuthukisiwe ze-hydration.

2. I-Viscosity:

• I-DS ephansi: I-CMC ene-DS ephansi ngokuvamile ibonisa i-viscosity ephansi endaweni ethile uma kuqhathaniswa namabanga aphezulu e-DS. Amaqembu ambalwa e-carboxymethyl aholela ekusebenzisaneni okumbalwa kwe-ionic kanye nezinhlangano ezibuthakathaka ze-polymer chain, okuholela ekwehleni kwe-viscosity.
• I-DS ephezulu: Amabanga aphezulu e-DS CMC avame ukuba ne-viscosity ephezulu ngenxa yokwanda kwe-ionization kanye nokusebenzisana okuqinile kweketango le-polymer. Inani elikhulu lamaqembu e-carboxymethyl likhuthaza ukubopha okubanzi kwe-hydrogen nokubambeka, okuholela ezisombululweni eziphezulu ze-viscosity.

3. Ukugcina Amanzi:

• I-DS ephansi: I-CMC ene-DS ephansi ingase ibe nomthamo wokugcina amanzi owehlisiwe uma kuqhathaniswa namabanga aphezulu e-DS. Amaqembu ambalwa e-carboxymethyl akhawulela inani lezindawo ezitholakalayo zokubopha nokumuncwa kwamanzi, okuholela ekugcinweni kwamanzi okuphansi.
• I-DS ephezulu: Amabanga aphezulu e-DS CMC ngokuvamile abonisa izakhiwo eziphakeme zokugcina amanzi ngenxa yenani elikhulayo lamaqembu e-carboxymethyl atholakalayo ukuze afakwe amanzi. Lokhu kuthuthukisa ikhono le-polymer lokumunca nokugcina amanzi, lithuthukise ukusebenza kwawo njengesilawuli esijiya, esihlanganisayo, noma somswakama.

4. Ukuziphatha Kwe-Rheological:

• I-DS ephansi: I-CMC ene-DS ephansi ivame ukuba nokuziphatha kokugeleza okwengeziwe kwe-Newtonian, nge-viscosity engancike kuzinga lokugunda. Lokhu kuyenza ifanelekele izinhlelo zokusebenza ezidinga i-viscosity ezinzile phezu kwenani elibanzi lamazinga okugunda, njengasekucutshungulweni kokudla.
• I-DS Ephakeme: Amabanga aphezulu e-DS CMC angase abonise i-pseudoplastic eyengeziwe noma i-shear-thinning thinning, lapho i-viscosity yehla ngokunyuka kwezinga lokugunda. Lesi sakhiwo sinenzuzo ezinhlelweni ezidinga ukumpompa kalula, ukufafaza, noma ukusabalalisa, njengamapende noma imikhiqizo yokunakekelwa komuntu siqu.

5. Ukuzinza Nokuhambisana:

• I-DS Ephansi: I-CMC ene-DS ephansi ingase ibonise ukuzinza okungcono nokuhambisana nezinye izithako ekwakhiweni ngenxa ye-ionization ephansi kanye nokusebenzisana okubuthakathaka. Lokhu kungavimbela ukuhlukaniswa kwesigaba, imvula, noma ezinye izinkinga zokuzinza kumasistimu ayinkimbinkimbi.
• I-DS ephezulu: Amabanga aphezulu e-DS CMC angase athambekele kakhulu ekujikeni noma ekuhlukaniseni kwesigaba ezixazululweni ezigxilile noma emazingeni okushisa aphezulu ngenxa yokusebenzisana kwe-polymer okuqinile. Ukwakhiwa nokucubungula ngokucophelela kuyadingeka ukuze kuqinisekiswe ukuzinza nokuhambisana ezimweni ezinjalo.

i-Degree of Substitution (DS) ithonya ngokuphawulekayo izinga, ukusebenza, nokufaneleka kwe-Carboxymethyl Cellulose (CMC) yezinhlelo zokusebenza ezihlukahlukene. Ukuqonda ubudlelwano phakathi kwezakhiwo ze-DS ne-CMC kubalulekile ekukhetheni ibanga elifanele ukuze kuhlangatshezwane nezimfuneko ezithile zokubunjwa kanye nemibandela yokusebenza.
