Izinzuzo ze-HPMC yezinga lemithi

I-HPMC hydroxypropyl methylcelluloseisibe ngesinye sezithako ezinkulu kakhulu zemithi ekhaya nakwamanye amazwe, ngoba i-HPMC inezinzuzo ezinye izithako ezingenazo.

1. Ukuncibilika kwamanzi

Iyancibilika emanzini abandayo angaphansi kuka-40 ℃ noma u-70% we-ethanol, futhi ayincibiliki emanzini ashisayo angaphezu kuka-60 ℃, kodwa ingafakwa ijeli.

2. Ukungasebenzi kahle kwamakhemikhali

I-HPMC uhlobo lwe-non-ionic cellulose ether. Isixazululo sayo asithwali i-ionic charge futhi asihlangani nosawoti wensimbi noma ama-ionic organic compounds. Ngakho-ke, ezinye izinto ezisizayo azisabelani nayo ngesikhathi senqubo yokulungiselela.

3. Ukuqina

Izinzile kakhulu ku-asidi kanye ne-alkali, futhi ingagcinwa isikhathi eside phakathi kwe-pH 3 ~ 11, futhi i-viscosity yayo ayinalo ushintsho olucacile. Isixazululo samanzi se-HPMC sinomphumela wokulwa nokukhunta futhi singagcina ukuzinza okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside. Izinto ezisizayo zemithi ezisebenzisaI-HPMCzinokuqina okungcono kwekhwalithi kunalezo ezisebenzisa izinto ezisizayo zendabuko (njenge-dextrin, isitashi, njll.).

4. Ukulungiswa kwe-viscosity

Izinhlobo ezahlukene ze-viscosity derivatives ze-HPMC zingaxutshwa ngezilinganiso ezahlukene, futhi i-viscosity yayo ingashintsha ngokuya ngomthetho othile, futhi inobuhlobo obuhle obuqondile, ngakho-ke ingakhethwa ngokuya ngesidingo. 2.5 I-Metabolic inertia I-HPMC ayimuncwa noma ayigaywa emzimbeni, futhi ayinikezi amakhalori, ngakho-ke iyisithako esiphephile semithi.

5. Ukuphepha

Ngokuvamile kubhekwa ukuthiI-HPMCakuyona into enobuthi futhi ayicasuli.

I-HPMC yezinga lemithi iyinto ebalulekile yokusetshenziswa ekukhiqizweni kwamalungiselelo okukhululwa okuqhubekayo nokulawulwayo. Ingumphelelisi wemithi osekelwa umbuso ocwaningweni nasekuthuthukisweni, futhi ihambisana nesiqondiso sokuthuthukiswa esisekelwa yinqubomgomo yezimboni kazwelonke. I-HPMC yezinga lemithi iyinto eyinhloko yokusetshenziswa ekukhiqizweni kwama-capsule ezitshalo ze-HPMC, ebiza ngaphezu kwama-90% wezinto zokusetshenziswa zama-capsule ezitshalo ze-HPMC. Ama-capsule ezitshalo akhiqizwe anezinzuzo zokuphepha nokuhlanzeka, ukusetshenziswa kabanzi, ukungabi nengozi yokusabela okuxhumene, kanye nokuqina okuphezulu, okuhambisana nokulindelwe ngabathengi. Izidingo zokuphepha nokuhlanzeka kokudla nemithi zingenye yezithako ezibalulekile kanye nemikhiqizo engcono kakhulu yokufaka esikhundleni sama-capsule e-gelatin ezilwaneni.
