3. Inkqubo yokuVelisa

Ukuveliswa kwe-Hypromellose kubandakanya i-etherification ye-cellulose kunye ne-propylene oxide kunye ne-methyl chloride.I-hydrolysis elandelayo ye-cellulose ether iphumela ekubunjweni kwe-Hypromellose.Inkqubo yokuvelisa ilawulwa ngononophelo ukufezekisa amanqanaba athile okutshintshwa kunye nobunzima bemolekyuli.

4. Izicelo zezamayeza

4.1 Umntu oncedisayo kwiiFom zeDosi yeDosa

I-Hypromellose isetyenziswa ngokubanzi njenge-excipient kwishishini lamachiza, ngakumbi ekuqulunqweni kweefom zedosi eqinile ezifana neepilisi kunye neepilisi.Indima yayo ekwandiseni ukupheliswa kwechiza kunye nokubonelela ngokukhululwa okulawulwayo kubalulekile kunikezelo lwamachiza olupheleleyo.

4.2 Iifomyula eziLawulwayo zokuKhululwa

Ukukwazi kwe-Hypromellose ukwenza i-gelatinous matrix xa i-hydrated yenza ukuba ilungele ukuqulunqwa kokukhululwa okulawulwayo.Le propati isetyenziselwa ukulungelelanisa amazinga okukhutshwa kweziyobisi, ukuphucula ukuthotyelwa kwesigulane kunye neziphumo zonyango.

4.3 Ukugqunywa kweFilimu kwiitafile

I-Hypromellose lukhetho oludumileyo lweetafile zokugquma ifilimu, ebonelela ngoluhlu olukhuselayo oluvala incasa, luququzelele ukuginya, kwaye lulawule ukukhutshwa kweziyobisi.Esi sicelo sibalulekile kuphuhliso lweefomu zedosi yamayeza yanamhlanje.

5. Ukutya kunye nezicelo zokuthambisa

5.1 Ishishini lokutya

Kwishishini lokutya, iHypromellose isebenza ngeenjongo ezahlukeneyo, kubandakanya ukutyeba, ukumilisela, kunye nokuzinzisa.Isetyenziswa ngokuqhelekileyo ekuqulunqweni kweemveliso zokutya ezifana neesosi, izambatho, kunye nezinto zokubhaka.

5.2 Izithambiso kunye noNonophelo lomntu

I-Hypromellose ifumana izicelo kwiimveliso zokuthambisa kunye neemveliso zokhathalelo lomntu ngenxa yokwenziwa kwefilimu kunye neempawu ezityebileyo.Inegalelo ekubunjweni nasekuzinzeni kweekhrimu, izinto zokuthambisa, kunye neshampu.
