I-Viscosity yiparameter ebalulekileyo yokusebenza kwe-hydroxypropyl methylcellulose (HPMC). I-HPMC isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yepolymer enyibilikayo yamanzi, i-non-ionic, i-non-toxic kunye nezinye iipropati. Inomsebenzi ogqwesileyo wefilimu, ukuqina kunye nokunamathela, okwenza kube yinto ekhangayo kwizicelo ezahlukeneyo.
I-Viscosity ngumlinganiselo wokumelana nolwelo lwangaphakathi lokuhamba. Ngamanye amazwi, ilinganisa ukutyeba okanye ukubhitya kolwelo. I-Viscosity yiparameter ebalulekileyo yokusebenza kwe-HPMC njengoko ichaphazela iimpawu zokuhamba kwesisombululo. Ukuphakama kwe-viscosity, isisombululo esiphezulu kwaye sihamba ngokukhawuleza. I-Viscosity inempembelelo ngqo kwisicelo kunye nokusebenza kwe-HPMC.
Esinye sezicelo ezibalulekileyo ze-HPMC sinjenge-thickener. Ngenxa yobunzima bayo obuphezulu bemolekyuli kunye neempawu zokuhlangana kwehydrogen, i-HPMC yenza into efana nejeli eshinyeneyo xa inyibilikiswa emanzini. I-viscosity ye-HPMC ibalulekile ekunqumeni ukuhambelana kwesisombululo. Ukuphakama kwe-viscosity, isisombululo esiphezulu. Le propati yenza ukuba ilungele ukutyeba izicelo kwiimveliso ezifana neepeyinti, iingubo kunye ne-adhesives.
Esinye isicelo esibalulekileyo se-HPMC ngamayeza. Isetyenziswa njenge-excipient kwiifom ezahlukeneyo ezifana neepilisi, ii-capsules kunye ne-ointments. I-viscosity ye-HPMC idlala indima ebalulekileyo ekuqulunqweni kwezi mveliso. Ichaphazela ukuhamba, ukuhambelana kunye nokuzinza kokuqulunqwa. I-viscosity efanelekileyo iyafuneka ukuze kuqinisekiswe ukuba imveliso kulula ukuyiphatha kwaye inokujongwa ngokuchanekileyo. I-HPMC ine-viscosity ephantsi xa inyibilika emanzini, iyenza ilungele ukulungiselela izisombululo kunye nokumiswa.
I-Viscosity ikwadlala indima ebalulekileyo ekusebenzeni kwe-HPMC kushishino lokwakha. Isetyenziswa ngokubanzi njenge-thickener kunye ne-binder kwizinto ezisekelwe kwisamente ezifana nodaka kunye ne-grout. I-viscosity ye-HPMC imisela inkqubo kunye nokulula kokusetyenziswa kwezi zixhobo. I-viscosity efanelekileyo iyadingeka ukuze kuqinisekiswe ukuba izinto eziphathekayo zinokusetyenziswa ngokulula kwaye zisasazeke ngokulinganayo. I-HPMC inozinzo oluhle kakhulu lwe-viscosity eyenza ilungele izicelo zokwakha.
I-Viscosity ikwachaphazela ubomi beshelufu yeemveliso ze-HPMC. I-viscosity ye-HPMC inokunyusa okanye iyancipha ngenxa yezinto ezininzi ezifana nobushushu, i-pH kunye nokugxila. Utshintsho kwi-viscosity lunokuchaphazela iipropati zemveliso kunye nokusebenza, okubangelwa ukungaphumeleli kwemveliso okanye ukunciphisa ukusebenza kakuhle. Ngoko ke, i-viscosity yeemveliso ezisekelwe kwi-HPMC kufuneka igcinwe ukuqinisekisa ukuzinza kunye nokusebenza kakuhle.
I-Viscosity yiparameter ephambili yokusebenza kwe-hydroxypropylmethylcellulose (HPMC). Ichaphazela iimpawu zokuhamba, ubukhulu kunye nokusebenza kweemveliso ze-HPMC. I-viscosity efanelekileyo iyadingeka ukuze kuqinisekiswe ukuba imveliso ilula ukuyisebenzisa kunye nemitha, inozinzo oluhle kwaye iyasebenza ekuhambeni kwexesha. I-HPMC inozinzo oluhle kakhulu lwe-viscosity, eyenza ibe yinto ekhangayo yokuzikhethela kwiintlobo ezahlukeneyo zezicelo kumashishini afana namayeza, ukwakhiwa kunye nokunyamekela komntu.
