Impembelelo ye-DS kwi-carboxymethyl cellulose Umgangatho

I-Degree of Substitution (DS) yiparameter ebalulekileyo echaphazela kakhulu umgangatho kunye nokusebenza kweCarboxymethyl Cellulose (CMC). I-DS ibhekisa kwi-avareji yenani lamaqela e-carboxymethyl afakwe kwiyunithi nganye ye-anhydroglucose yomqolo we-cellulose. Ixabiso le-DS lichaphazela iipropati ezahlukeneyo ze-CMC, kuquka ukunyibilika kwayo, i-viscosity, umthamo wokugcinwa kwamanzi, kunye nokuziphatha kwe-rheological. Nantsi indlela i-DS ewuchaphazela ngayo umgangatho we-CMC:

1. Ukunyibilika:

• I-DS ephantsi: I-CMC ene-DS ephantsi ithande ukunganyibiliki kancinci emanzini ngenxa yamaqela ambalwa e-carboxymethyl akhoyo kwi-ionization. Oku kunokubangela ukucotha kwamazinga onyibiliko kunye namaxesha amade okugalela amanzi.
• I-DS ephezulu: I-CMC ene-DS ephezulu i-soluble ngakumbi emanzini, njengoko inani elongezelelweyo lamaqela e-carboxymethyl liphakamisa i-ionization kunye ne-dispersibility yamaketanga e-polymer. Oku kukhokelela ekunyibilikeni ngokukhawuleza kunye neempawu eziphuculweyo ze-hydration.

2. IViscosity:

• I-DS ephantsi: I-CMC ene-DS ephantsi idla ngokubonisa i-viscosity esezantsi kwindawo ethile yoxinaniso xa kuthelekiswa namabanga aphezulu e-DS. Amaqela ambalwa e-carboxymethyl abangela ukudibana okumbalwa kwe-ionic kunye nemibutho ebuthathaka ye-polymer chain, ekhokelela kwi-viscosity ephantsi.
• I-DS ephezulu: Amabakala e-DS aphezulu e-CMC athanda ukuba ne-viscosity ephezulu ngenxa yokwanda kwe-ionization kunye nokunxibelelana okunamandla kwe-polymer chain. Inani elikhulu lamaqela e-carboxymethyl likhuthaza ukudibanisa okubanzi kwe-hydrogen kunye nokubanjwa, okukhokelela kwizisombululo eziphezulu ze-viscosity.

3. Ugcino lwamanzi:

• I-DS ephantsi: I-CMC ene-DS ephantsi inokuba nomthamo wokugcina amanzi ocuthiweyo xa kuthelekiswa namabanga aphezulu e-DS. Amaqela amancinci e-carboxymethyl anciphisa inani leendawo ezifumanekayo zokubophelela kwamanzi kunye nokufunxa, okukhokelela ekugcinweni kwamanzi okuphantsi.
• I-DS ephezulu: Amabakala aphezulu e-DS CMC abonisa iimpawu eziphezulu zokugcina amanzi ngenxa yokwanda kwenani lamaqela e-carboxymethyl akhoyo kwi-hydration. Oku kwandisa amandla epolymer ukufunxa nokugcina amanzi, iphucula ukusebenza kwayo njengento ejiyayo, ibhinda, okanye isilawuli sokufuma.

4. Ukuziphatha ngokweRheological:

• I-DS ephantsi: I-CMC ene-DS ephantsi ithande ukuba ne-Newtonian flow behavior, kunye ne-viscosity ezimeleyo kwizinga lokucheba. Oku kuyenza ilungele izicelo ezifuna i-viscosity ezinzileyo kuluhlu olubanzi lweereyithi zokucheba, ezifana nokulungiswa kokutya.
• I-DS ephezulu: Amabakala aphezulu e-DS CMC angabonisa ngakumbi i-pseudoplastic okanye ukuziphatha okuchebayo, apho i-viscosity iyancipha ngokunyuka kwesantya sokucheba. Le propati inenzuzo kwizicelo ezifuna ukulula ukumpompa, ukutshiza, okanye ukusabalalisa, njengepeyinti okanye iimveliso zokunakekelwa komntu.

5. Uzinzo kunye nokuhambelana:

• I-DS ephantsi: I-CMC ene-DS ephantsi ingabonakalisa ukuzinza okungcono kunye nokuhambelana nezinye izithako ekuqulunqweni ngenxa ye-ionization ephantsi kunye nokusebenzisana okubuthathaka. Oku kunokuthintela ukuhlukana kwesigaba, imvula, okanye eminye imiba yokuzinza kwiinkqubo ezinzima.
• I-DS ephezulu: Amabakala aphezulu e-DS CMC anokuthi athandeke ngakumbi kwi-gelation okanye ukuhlukana kwesigaba kwizisombululo ezigxininisiweyo okanye kumaqondo okushisa aphezulu ngenxa yokusebenzisana kwepolymer enamandla. Ukuqulunqwa ngononophelo kunye nokucubungula kuyafuneka ukuqinisekisa uzinzo kunye nokuhambelana kwiimeko ezinjalo.

iDegree of Substitution (DS) ichaphazela kakhulu umgangatho, ukusebenza, kunye nokufaneleka kweCarboxymethyl Cellulose (CMC) kwizicelo ezahlukeneyo. Ukuqonda ubudlelwane phakathi kweempawu ze-DS kunye ne-CMC kubalulekile ekukhetheni ibakala elifanelekileyo ukuhlangabezana neemfuno ezithile zokuqulunqwa kunye neendlela zokusebenza.
