Izinto ezichaphazelayo kwi-carboxymethylcellulose ityuwa yesodium Isisombululo sokuziphatha

Ityuwa ye-Carboxymethylcellulose sodium (CMC-Na) i-polymer enyibilikayo emanzini esetyenziswa ngokuqhelekileyo kwizicelo ezahlukeneyo zoshishino kunye nezorhwebo, kuquka ukutya, amayeza, kunye neemveliso zokhathalelo lomntu. Ukuziphatha kwezisombululo ze-CMC-Na kuphenjelelwa zizinto ezininzi, ezinye zazo zixutyushwa ngezantsi:

1. Ubunzima bemolekyuli: Ubunzima bemolekyuli ye-CMC-Na buphembelela indlela yokuziphatha kwesisombululo, i-viscosity, kunye neempawu zerheological. Ubunzima bemolekyuli ephezulu ye-CMC-Na iipolima zihlala zinesisombululo esiphezulu se-viscosity kwaye zibonisa ukuziphatha okukhulu kokucheba kunokulinganisa ubunzima bemolekyuli.
2. Ugxininiso: Ukugxininiswa kwe-CMC-Na kwisisombululo kukwachaphazela ukuziphatha kwayo. Kwiindawo ezisezantsi, izisombululo ze-CMC-Na ziziphatha njengolwelo lwe-Newtonian, ngelixa kwiindawo eziphezulu, ziba yi-viscoelastic ngakumbi.
3. Amandla e-Ionic: Amandla e-ionic esisombululo sinokuchaphazela ukuziphatha kwe-CMC-Na izisombululo. Uxinzelelo oluphezulu lwetyuwa lunokubangela ukuba i-CMC-Na idityaniswe, nto leyo ekhokelela ekwandeni kwe-viscosity kunye nokuncipha kokunyibilika.
4. I-pH: I-pH yesisombululo inokuchaphazela ukuziphatha kwe-CMC-Na. Kwixabiso eliphantsi le-pH, i-CMC-Na inokuba yiprotonated, ekhokelela ekunciphiseni ukunyibilika kunye nokwanda kwe-viscosity.
5. Ubushushu: Ubushushu besisombululo bunokuchaphazela ukuziphatha kwe-CMC-Na ngokuguqula ukunyibilika kwayo, i-viscosity, kunye nokuziphatha kwe-gelation. Amaqondo obushushu aphezulu anokunyusa ukunyibilika kwe-CMC-Na, ngelixa amaqondo obushushu asezantsi anokubangela i-gelation.
6. Izinga le-Shear: Isantya sokucheba okanye isantya sokuhamba kwesisombululo sinokuchaphazela ukuziphatha kwe-CMC-Na ngokuguqula i-viscosity yayo kunye neempawu ze-rheological. Kumazinga aphezulu okucheba, izisombululo ze-CMC-Na ziba zincinci kakhulu kwaye zicheba ngakumbi.

Lilonke, ukuziphatha kwezisombululo ze-CMC-Na kuphenjelelwa zizinto ezininzi, kubandakanya ubunzima bemolekyuli, ugxininiso, amandla e-ionic, i-pH, ubushushu, kunye nesantya sokucheba. Ukuqonda le miba kubalulekile ekuyileni nasekuphuculeni iCMC-Na-based formulations kwizicelo ezahlukeneyo.
