Izinto ekufuneka ziqwalaselwe xa u-Viscofity of Subs-hip

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) ingumyinge obalulekileyo kwi-fart ezixutywe imixube, ukuphucula iipropathi ezinje ngokusebenza, ukugcinwa kwamanzi, kunye nokunamathela amanzi, kunye nokunamathela amanzi, kunye nokunamanzi. Ukulinganisa i-viscosity ye-HPMC kwi-fers exutyweyo kubalulekile ekuqinisekiseni umgangatho wokusebenza kunye nokusebenza. I-Viskosity ichaphazela lula ukuphuculwa kwesicelo, ixesha lokuseta, kunye namandla okugqibela kodaka.

Izinto ezichaphazela umlinganiso we-viscosity
I-1. Ukuqulunqwa kodaka oluxubileyo
Ukuqulunqwa kobukhoboka obuxubeneyo kubandakanya isamente, ukwahlula-hlulwa, ukongeza njenge-HPMC, kwaye ngamanye amaxesha ezinye ii-polymers. Inxalenye yezi zinto ichaphazela i-viscofity. Ukugxininiswa okuphezulu kwe-HPMC ngokubanzi kukonyusa i-viscofity ngenxa yeepropathi zayo zokuthambisa. Ukongeza, uhlobo kunye nokuhla kwe-Agegregates kunokuphembelela iimpawu zokuhamba kodaka.

2. Inkqubo yokuxubusha
Indlela kunye nexesha lokuxuba zinefuthe elibonakalayo kumlinganiso we-viscosity. Ukuxutywa angonelanga kunokukhokelela kumxube onomonde, okhokelela kwi-viscotity vingsm. Ukuxuba ngokuchanekileyo kuqinisekisa ukuba i-HPMC ichithwa ngokupheleleyo elulalweni, ibonelela ngeziphumo ezingaguqukiyo. Ukuxuba isantya, ixesha, kunye nohlobo lwezixhobo kufuneka zibekwe emgangathweni kwimilinganiselo ethembekileyo.

I-3. Ubungakanani bamanzi
Umyinge wamanzi-uqinile oqinileyo Umxholo ophezulu wamanzi ngokubanzi uphantsi i-viscosity, esenza udaka olunamanzi. Kwelinye icala, umxholo osezantsi wenza isiphumo esiphezulu, umxube ongaphezulu. Ukungqinelana kumlinganiso we-W / S kubalulekile ekumiselweni kweMilinganiselo yokuzala.

4. Ubushushu
Ubushushu buchaphazela uVeksinity weZisombululo ze-HPMC ngokubalulekileyo. Njengoko ubushushu buyanda, i-viscosity ye-HPMC iyancipha ngenxa yokuncitshiswa kokudibana kwemolekyuli. Ke ngoko, kubalulekile ukuba uqhube imilinganiselo ye-viscofity kwiqondo elilawulwayo nelingaguqukiyo ukunqanda ukwahluka kweziphumo.

I-5. Inqanaba le-pH
Inqanaba le-PH yomxube ongumdaka zinokuba nefuthe kwi-HPMC. I-HPMC ibonakalisa ukuviwa okwahlukileyo kumanqanaba e-PH, kunye nemilinganiselo ye-PH efanelekileyo enokubakho ekukhokeleni i-polymer kunye ne-vikosity eguqulweyo. Ukugcina ukungathathi cala ukuba i-alkaline i-alkaline ph ilungele ukufundwa kwezinzile.

I-6. Ubudala bodaka
Iminyaka ubudala okanye ixesha elidlulileyo emva kokuxuba kunokuba nefuthe kwi-viscogosity yodaka. Inkqubo ye-hydmc ye-HPMC inokuqhubeka ixesha elide, ngokuthe ngcembe iguqula i-viscofity. Imilinganiselo kufuneka ithathwe ngexesha lokungaguquguquki emva kokuxuba ukuqinisekisa ukuthelekiswa.

7. Izixhobo zokulinganisa
Ukukhetha isixhobo sokulinganisa uVeksisity kubalulekile. Izixhobo eziqhelekileyo zibandakanya iirekhodi zokuhamba-hlula, ii-capite vimeres, kunye nee-rheometers. Isixhobo ngasinye sinemigaqo yawo yokusebenza kunye nokufaneleka kuxhomekeka kuluhlu lwe-viscofity kunye neempawu ezithile zodaka. Ukulungisa nokulondolozwa kwezi zixhobo kubalulekile kwiMilinganiselo echanekileyo.

Ukulinganisa i-viscosity yodaka oluxubeneyo equkethwe i-HPMC yinkqubo eyahlukeneyo ephembelela izinto ezahlukeneyo kubandakanya ukwakhiwa, iinkqubo zamanzi, amanqanaba e-PH, kunye nobudala be-PH. Iiprothokholi ezisemgangathweni kunye nokuqwalaselwa ngononophelo kwezi zinto kubalulekile ukuze ufumane amanyathelo athembekileyo kwaye angaguqukiyo. Ngokujongana nemiceli mngeni kunye nokuphumeza ezona ndlela zilungileyo, imilinganiselo echanekileyo yokufakelwa i-viscofity inokufezekiswa, kuqinisekisa ukusebenza okuthandayo kobukho bodaka oxubileyo kwizicelo zokwakha.
