Ngaba i-hypromellose acid?

I-Hypromellose, ekwabizwa ngokuba yi-hydroxypropyl methylcelcelsulose (i-HPMC), ayisiyo-Acid-ukunganyangeki. Nangona kunjalo, ukuchasana kwe-asidi ye-hypromellose kunokuphuculwa ngeendlela ezahlukeneyo zokwakha.

I-Hypromellose inyibilikiswa emanzini kodwa ingena-insullen kwizinyibilikisi eziphilayo kunye nolwelo olungezopolitiko. Ke ngoko, kwiindawo ze-acidic, ezinje ngesisu, i-hypromellose inokunyibilikisa okanye idumbele kwinqanaba elithile, kuxhomekeka kwizinto ezinje ngoxinzelelo lwe-acid, i-PH, kunye nexesha lokuvezwa.

Ukuphucula ukuxhathisa i-acid ye-hypromellose kwifom yamayeza, iindlela zokuthambeka kwe-Gornec zihlala zisetyenziswa. I-POREICS I-POSTITS isetyenziswa kwiitafile okanye iicaphule ukubakhusela kwindalo yesisu kwaye ibavumele ukuba badlulise kwindawo engathathi cala kwezopolitiko ngaphambi kokuba ukhuphe izithako ezisebenzayo.

I-POREIC I-POOATSS iqhelekwenziwa kwii-polymers ezinganyangekiyo kwi-Gastri Acid, njenge-Seletase i-pletate phthalate (i-HPMCPP), okanye i-Polyviny ye-PHTHAATE PHTHALATE (PVAP). Ezi polymers zenza umqobo okhuselayo kwithebhulethi okanye i-capsule, ukuthintela ukuchithwa kwangaphambili okanye ukonakaliswa esiswini.

Isishwankathelo, ngelixa i-hypromellose ngokwayo ayisiyo-icid, ukungaxhathisi i-asidi yayo kunokuphuculwa ngeendlela zendlela yokuqulunqwa okunjengokhupha ngaphakathi. Ezi ndlela zisetyenziswa rhoqo kwifomu yamayeza ukuqinisekisa ukuhanjiswa ngempumelelo kwezithako ezisebenzayo kwindawo ekusenziwa kuyo.
