I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-HPMC

I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-hydroxypropylylylylym methylcellulose (HPMC). I-HPMC isetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa ye-polymer yayo engenamanzi, okungeyona eye-ionic, engeyona eyenobuthi nezinye izakhiwo. Inezakhiwo ezinhle kakhulu zefilimu, zokuqina kanye nokunamathela, okwenza kube ukukhetha okukhangayo kwezicelo ezahlukahlukene.

I-Viscosity iyisilinganiso sokumelana kwangaphakathi koketshezi ukuze ageleze. Ngamanye amagama, ikala ubukhulu noma ukuncipha koketshezi. I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-HPMC njengoba kuthinta izici zokugeleza kwesixazululo. Lapho kuphakama i-viscosity, ubukhulu besixazululo kanye nokuhamba kancane kugeleza. I-Viscosity inomthelela oqondile ohlelweni nasekusebenzeni kwe-HPMC.

Enye yezicelo ezibalulekile ze-HPMC zinjengesikhulu. Ngenxa yesisindo sayo esiphakeme samangqamuzana kanye nezakhiwo ze-hpdrogen Bonding, i-HPMC yakha into enobukhulu obufana ne-gel lapho ichithwa emanzini. I-viscosity ye-HPMC ibalulekile ekunqumeni ukuvumelana kwesisombululo. Lapho kuphakama i-viscosity, ubukhulu besixazululo. Le mpahla yenza kube nento elungele ukusetshenziswa kwezicelo zokuqina kwemikhiqizo efana nopende, izimbobo kanye nokunamathela.

Olunye ukusetshenziswa okubalulekile kwe-HPMC yimithi. Isetshenziswa njenge-excipont kumiyalo ehlukahlukene efana namathebulethi, ama-caplule kanye namafutha. I-viscosity ye-HPMC idlala indima ebalulekile ekwakhekeni kwale mikhiqizo. Kuthinta ukuhamba, ukuguquguquka nokuqina kokwakhiwa. Ukubonakala okufanele kudingekile ukuqinisekisa ukuthi umkhiqizo kulula ukuphatha futhi ungahle usube ngokunembile. I-HPMC inokubonakala okuphansi lapho ichithwa emanzini, okwenza kube yinto elungele ukulungiselela izixazululo nokumiswa.

I-Viscosity nayo idlala indima ebalulekile ekusebenzeni kwe-HPMC embonini yezokwakha. Kusetshenziswa kabanzi njengomuntu omkhulu kanye ne-binter ezintweni ezisuselwa kuso usimende njengodaka kanye ne-grout. I-viscosity ye-HPMC inquma ukucubungulwa kanye nokusebenziseka kalula kwalezi zinto zokwakha. Ukubonakala okufanele kudingeka ukuqinisekisa ukuthi izinto ezibonakalayo zingasetshenziswa kalula futhi zisakazeke ngokulinganayo. I-HPMC inokuqina okuhle okubonakalayo okwenze ilungele izinhlelo zokwakha.

I-Viscosity ibuye ithinta impilo yeshalofu yemikhiqizo ye-HPMC. I-viscosity ye-HPMC ingakhuphula noma yehle ngenxa yezici ezimbalwa ezifana nokushisa, i-pH kanye nokuhlushwa. Izinguquko ekuboneni zingathinta izakhiwo zomkhiqizo nokusebenza, okuholele ekuhlulekeni komkhiqizo noma ukusebenza okuncishisiwe. Ngakho-ke, i-viscosity yemikhiqizo esekwe kwa-HPMC kumele igcinwe ukuze iqinisekise ukuqina nokusebenza kwayo.

I-Viscosity iyipharamitha esemqoka yokusebenza kwe-hydroxypropylmethylcellellellellellellellellellulose (HPMC). Kuthinta izici zokugeleza, ubukhulu kanye nokusebenza kwemikhiqizo ye-HPMC. I-viscosity efanele iyadingeka ukuze kuqinisekiswe ukuthi umkhiqizo kulula ukufaka amamitha namamitha, unokuqina okuhle futhi kuyasebenza ngokuhamba kwesikhathi. I-HPMC inokuqina okuhle kakhulu kokubonakalayo, okwenza kube ukukhetha okukhangayo kwezicelo ezahlukahlukene ezimbonini ezinjengemithi, ukwakhiwa kanye nokunakekelwa komuntu siqu.
