3. Ukuphucula ukuxhathisa kokuqhekeka
Udaka olulungisiweyo lwe-HPMC lunokumelana okugqwesileyo kokuqhekeka. Ukongeza i-HPMC kumdaka kunokuthintela ngokufanelekileyo ukubunjwa kweentanda zokucutheka. I-HPMC inciphisa ukuvela kwamanzi ngokukhawuleza kwamanzi ngokuphucula ukugcinwa kwamanzi odaka, ngaloo ndlela kuncitshiswe ukunyanzeliswa kokunciphisa okubangelwa yilahleko yamanzi. Oku kubaluleke ngakumbi kulwakhiwo olukhulu okanye kwizakhiwo ezivezwe kwiimeko ezomileyo kangangexesha elide.
Ukongeza, impembelelo eqinisayo ye-HPMC ikwanceda ekuphuculeni ukuxhathisa kokuqhekeka kodaka. I-HPMC inokwenza ulwakhiwo oluthile lwefiber microscopic kwinethiwekhi yodaka ukunyusa ukuqina kodaka, ngaloo ndlela ixhathisa uxinzelelo lwangaphandle kunye nokunciphisa ukwenzeka kweentanda. Ngokukodwa kwiinkqubo zokugquma eludongeni lwangaphandle, ukuxhathisa kokuqhekeka kwe-HPMC yodaka olulungisiweyo kudlala indima ephambili ekuphuculeni ukuqina kwayo yonke inkqubo.
4. Ukuphucula ukumelana nemozulu
Udaka olulungisiweyo lwe-HPMC lukwanokumelana nemozulu encomekayo kwaye inokugcina ukusebenza okuzinzileyo phantsi kweemeko ezahlukeneyo zemozulu. Ukongezwa kwe-HPMC kwenza ukuba udaka lube nokumelana nokunyibilika okungcono kwe-freeze kunye nokumelana ne-UV, ukwandisa ubomi benkonzo yodaka. Kwiindawo ezibandayo, udaka olulungisiweyo lwe-HPMC lunokuxhathisa ngokufanelekileyo umonakalo wemijikelo yokunyibilika komkhenkce kwaye luthintele ukutyibilika komkhenkce kumphezulu wodaka.
