Ukuxinana luphawu lokungahambelani kolwelo nokuhamba kwamanzi, enye yezinto ezichaphazela umgangatho wemveliso, ukusebenza kakuhle kwenkqubo kunye nokuthotyelwa kwemithetho.ulawulo lwe-viscosity olune-nlineiguqula ukwenziwa kwamayeza ngokuvumela ukujonga nokulungisa ngexesha langempela, isuse ukulibaziseka kunye nokungangqinelani kweendlela zemveli ezisekelwe kwilebhu.
Ukuqina Kwenkqubo Kwishishini Lezonyango
Ukuqina kwe-in-processibhekisa ekulinganisweni kwexesha langempela kunye nolawulo lokumelana nokuhamba kolwelo ngexesha lokwenziwa kwamayeza. Uvavanyo lwe-viscosity olusekelwe kwilebhu yendabuko, olubandakanya iisampulu zamaxesha athile kunye nohlalutyo olungaxhunyiwe kwi-intanethi; ukujonga i-viscosity kwinkqubo kubonelela ngedatha eqhubekayo ngqo ukusuka kumgca wemveliso.
Kubaluleke kakhulu kwi consistenti-visci-osityulondolozongaphakathiiinkqubo zokwenza iimveliso eziqhubekayo kwii-suspensions, ii-gels, kunye nee-emulsions, njl. Umzekelo, i-viscosity yesisombululo se-monoclonal antibody inokubangela ukuba ifakelwe, ngelixa i-viscosity ye-gel engaphandle ichaphazela ukusasazeka kwayo kunye nokwamkelwa kwesigulana.
Ulawulo lwe-viscosity ngexesha langempela luqinisekisa ukuba ukuphambuka kubanjwa ngoko nangoko, okuvumela uhlengahlengiso kwi-formulation okanye kwi-process parameters ukugcina ukuthotyelwa kwemigangatho engqongqo yolawulo. Ngokufaka uhlolo lwe-viscosity kumjelo wemveliso, abavelisi banokufezekisa ukuhlanganiswa okungenamthungo kunyeimveliso eqhubekayo yamayeza, ukuphucula imveliso kunye nokuthembeka kwemveliso.
Izinto Ezichaphazela Ukulinganisa Ukuxinana
Ukulinganiswa kwe-viscosity echanekileyo kubalulekile kodwa kunokuguquguquka zizinto ezininzi, nganye ifuna ukuqwalaselwa ngononophelo ukuqinisekisa idatha ethembekileyo kwiukuvelisa amayeza okuqhubekayo:
●Ubushushu: Ukuqina komzimba kuchaphazeleka kakhulu kutshintsho lobushushu. Ukwehla nje kwe-1°C kunokunyusa ukuqina komzimba ukuya kuthi ga kwi-10%, njengoko ulwelo luba nokumelana nokuhamba kwamanzi kubushushu obuphantsi. Ulawulo lobushushu oluchanekileyo, oluhlala lungaphakathi kwe-0.02°C, lubalulekile ukuze kulinganiswe ngokulinganayo.
●Izinga lokucheba: Ulwelo olungelulo ulwelo lwaseNewtonian, oluxhaphakileyo kwimithi, lubonisa utshintsho kwi-viscosity phantsi kwamazinga ahlukeneyo okucheba. Ulwelo olucheba njengeejeli luyancipha kwi-viscosity phantsi kokucheba okuphezulu, ngelixa ulwelo olutyebayo lusanda.
●Ukwakheka kunye nokugxila: Amanqanaba aphezulu ezithako ezisebenzayo zamayeza (ii-API) okanye izinto ezincedisayo anokunyusa kakhulu i-viscosity, ngakumbi kwi-biologics ezifana ne-monoclonal antibodies ezingaphezu kwe-100 mg/mL.
●UxinzeleloNangona ingenampembelelo ingako kuneqondo lobushushu, uxinzelelo lunokuchaphazela i-viscosity, ingakumbi kwiinkqubo zoxinzelelo oluphezulu ezifana neempompo okanye ii-extruders, apho uxinzelelo olongezelelweyo lunciphisa ukuhamba kwee-molecular, nto leyo ephakamisa i-viscosity.
●Ukulingana kwesampulu: Iisampuli ezingalinganiyo, ezifana nokumiswa okune-sedimentation okanye amaqamza omoya, zinokutshintsha imilinganiselo, nto leyo enokubangela ukuba kudityaniswe okanye kukhutshwe igesi ngokufanelekileyo ngaphambi kohlalutyo.
Impembelelo yokuxinana kweenkqubo zokuvelisa
Ukuqina kwe-viscosity kunefuthe ekusebenzeni kakuhle nakumgangatho we-ukwenziwa rhoqo kwamayezakwiinqanaba ezininzi:
●Ukuxuba: Ukuqina kulawula ukufana nokusebenza kakuhle kokuxuba ii-API kunye nezinto ezincedisayo. Ukuqina okuphezulu kufuna abaxubi abaqinileyo (umz., abashukumisi bee-anchor) ukuthintela ukwahlukana kwesigaba, ngelixa ukuqina okuphantsi kunokukhokelela ekuxubeni kakhulu nasekungeneni komoya.
●Ukuzalisa: Ukuzaliswa ngokuchanekileyo kweebhotile, iisirinji, okanye iikhaphu kuxhomekeke kwi-viscosity. Ulwelo olune-viscosity ephezulu lunokubangela ukuvaleka okanye idosi engahambelaniyo, nto leyo echaphazela ukuchaneka, ngelixa ulwelo olune-viscosity ephantsi lunokubangela ukutshiza okanye ukuvuza.
●Ukupakisha: Ukuxinana kuchaphazela uzinzo kunye nokuthembeka kweemveliso ezipakishiweyo. Umzekelo, iifomyula ezixineneyo kakhulu zisenokungangeni kakuhle kwizikhongozeli, ngelixa iimveliso ezixineneyo kancinci zibeka emngciphekweni wokuvuza okanye ukungazinzi ngexesha lokugcina.
●Ukupompa kunye nokugeleza kwamanzi: Ukuqina kumisela ukufuthwa kwamanzi kunye nokuziphatha kokuhamba kwamanzi ngemibhobho. Ukuqina kwamanzi okuphezulu kwandisa ukwehla koxinzelelo, kufuna amandla aphezulu okufaka, ngelixa ukuqina kwamanzi okuphantsi kunokubangela ukuhamba kwamanzi okuphazamisayo, okuchaphazela ulawulo lwenkqubo.
●Ukusebenza kwesicelo: Kwizitofu ezifakwa kwinaliti, i-viscosity ichaphazela ukukwazi ukugaya kunye nokuthuthuzela kwesigulana, ngelixa kwi-oral suspensions, ichaphazela ukuncasa kunye neempawu zokugquma umphimbo.
Imbali yoMxholo kunye noTshintsho loMlinganiselo woBungqingili
Ukulinganiswa kwe-viscosity kuye kwanda kakhulu, kuqhutywa yimfuno yokuchanekaiinkqubo zokwenza iimveliso eziqhubekayoEkuqaleni kwenkulungwane yama-20, i-viscosity yayilinganiswa ngesandla kusetyenziswa izixhobo ezilula ezifana neekomityi zokuhamba kunye nee-viscometer zeglasi ze-capillary, ezazixhomekeke ekuhambeni okuqhutywa ngumxhuzulane.
Ezi ndlela, nangona zisebenza kwi-Newtonian fluids, zazifuna umsebenzi omninzi kwaye azifanelekanga ukujongwa ngexesha langempela. Ukuqaliswa kwee-viscometers ezijikelezayo phakathi kwinkulungwane yama-20 kwaphawula ukunyukela phambili, okuvumela ukulinganiswa kwe-viscometer enamandla kwi-non-Newtonian fluids. Ukufika kwe-automation ngasekupheleni kwenkulungwane yama-20 kwazisa "ii-algorithms zokuphilisa" zokulandelela utshintsho lwe-viscometer ngexesha lee-reactions.
