Rheology le khokahano ea hydroxypropyl methylcellulose (HPMC) le hydroxypropyl starch (HPS) li na le karolo ea bohlokoa liindastering tse fapaneng, ho kenyeletsoa meriana, lijo, litlolo le kaho.Ho utloisisa tšebelisano lipakeng tsa li-polymer tsena tse peli ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea bona le ho nts'etsapele lihlahisoa tse ncha.Pampiri ena e ikemiselitse ho hlahloba thepa ea rheological le ho lumellana ha HPMC/HPS complex.
Lintho tsa Rheological:
Rheology ke thuto ea hore na thepa e senyeha joang le ho phalla tlas'a tšusumetso ea matla a ka ntle.Tabeng ea HPMC/HPS complex, thepa ea rheological e khetholla viscosity, boitšoaro ba gelation, le thepa ea phallo ea kakaretso ea motsoako oa polymer.Boitšoaro ba rheological bo rarahaneng bo ka angoa ke lintlha tse joalo ka mahloriso a polymer, boima ba limolek'hule, mocheso le sekhahla sa ho kuta.
Ho lumellana ha HPMC le HPS:
Ho lumellana lipakeng tsa HPMC le HPS ho bohlokoa ho netefatsa ho theoa ha li-complexes tse tsitsitseng tse nang le thepa e lakatsehang.Ho lumellana ho bolela bokhoni ba li-polymer tse peli kapa ho feta ho kopanya le ho theha tsamaiso e ts'oanang ntle le karohano ea mekhahlelo kapa tahlehelo ea ts'ebetso.
Lintlha tse amang rheology le tumellano:
Karo-karolelano ea polymer: Karo-karolelano ea HPMC ho HPS e rarahaneng e ka ama haholo thepa ea eona ea rheological le ho lumellana.
Boima ba limolek'hule: Boima ba limolek'hule tsa HPMC le HPS bo ama rheology le ho lumellana ha lintho tse rarahaneng.
Mocheso: Mocheso oo motsoako o rarahaneng o lokiselitsoeng le ho lekoa ho oona o ama boitšoaro ba eona ba rheological.
Sekhahla sa ho kuta: Sekhahla sa ho kuta se sebelisoang nakong ea tlhahlobo kapa ho sebetsa se ka ama thepa ea rheological ea HPMC/HPS complex.Likhahla tse phahameng tsa ho kuta li ka lebisa boitšoarong ba ho kuta, moo viscosity e fokotsehang ka sekhahla sa ho kuta.
