Kodi ndi chiyani chambiri chaHpmc?

Hydroxypylferose (hpmc) ndi polimmer yosiyanasiyana yomwe imapezeka kwambiri m'mafakitale osiyanasiyana, kuphatikizapo mankhwala osokoneza bongo, zomangamanga, ndi zodzola zake. Rhelogy ndi kafukufuku woyenda ndi kusinthika kwa zinthu, ndikumvetsetsa za HPMC ndikofunikira kuti muthe kukonza magwiridwe antchito osiyanasiyana.

Ma Isccess: HPMC imawonetsa machitidwe a pseudoplastic kapena sheent, kutanthauza kuti ma viscy amachepetsa ndikuwonjezeka. Katunduyu ndi wofunikira pakugwiritsa ntchito monga mankhwala mapangidwe a mankhwala, pomwe umalola kuti kupondereza kosatha, kufalikira, ndi kugwiritsa ntchito. Makulidwe amatha kusinthidwa posintha kuchuluka kwa zolowa m'malo mwa HPMC.

Thixotropy: Thixotropy amatanthauza kusintha kwa gel-sol yowonetsedwa ndi zinthu zina zomwe zimapanikizika. Ma gels a HPMC omwe amapangidwa kuti apumule amatha kusweka pansi kukameta ubweya ndikuyambiranso kuphatikizika kwa gel pamene nkhawa imachotsedwa. Katunduyu ndiwopindulitsa pakugwiritsa ntchito ngati utoto, pomwe umalepheretsa kusaka nthawi yogwiritsira ntchito koma amawonetsetsa kuti zokutira bwino nthawi ina.

Hydration: hpmc ndi hygroscopic ndipo imatha kuyamwa madzi, kuchititsa kuti zitupa komanso kuchuluka kwa mamasukidwe. Kuchuluka kwa hydration kumadalira zinthu monga kutentha, Ph, ndi ionic mphamvu ya sing'anga yozungulira. Kuleza mtima kumathandizanso kuwongolera kumasulidwa kwa mankhwala osokoneza bongo kuchokera ku mapangidwe a mankhwala a mankhwala ndikukhalabe chinyezi.

Kukhuta kutentha:HpmcMayankho amawonetsa kutentha kwa kutentha, ndi mafayilo ocheperako ngati kutentha kumawonjezeka. Komabe, izi zimatha kukhala zosiyanasiyana kutengera zinthu monga polymer ndende ndi yankho la PH. Kukhutiritsa kutentha ndikofunikira pakugwiritsa ntchito ngati zinthu zomanga, komwe zimakhudza kugwirira ntchito komanso kukhazikitsa nthawi.

Kukhuta kwamchere: Mayankho a HPMC akhoza kuwonetsa kukhudzidwa kwa mchere, ndi mchere wina woyambitsa mavckon mpaka kusokoneza mafayilo. Izi zimadziwika kuti zimakhudzana ndi mamolekyulu a HPMC ndi ma ion. Kukhuta kwamchere ndikofunikira pamapangidwe opangira mankhwala ndi zakudya zomwe mchere umayenera kulamuliridwa mosamala.

Kukhulupirika ku Shear: Kukhazikika kwa ziphuphu kwa HPMC kumadalira kwambiri kuchuluka kwa misempha yomwe imagwiritsidwa ntchito. Mitengo yotsika ivear, mafayilo akukwera chifukwa chowonjezereka kuti atengedwe, pomwe kuchuluka kwa mitengo yayikulu, mahekidwe amachepetsa kupatulira. Kuzindikira kwa Shear Shear ndikofunikira popanga malo ogwiritsira ntchito zinthu zosiyanasiyana.

Kuyimitsidwa kwa tinthu: HPMC imatha kukhala ngati kuyimitsa kwa tinthu tambiri timadzimadzi chifukwa cha kukula kwake ndikukhazikitsa malo. Zimathandiza kupewa kukhazikika tinthu tokhazikika, kuonetsetsa kugawa yunifolomu komanso kusasinthika kwa zinthu monga zotupa, zomata, kuyimitsidwa kwa mankhwala.

Kupanga kwa gel:Hpmcimatha kupanga ma gels pamalo ozungulira kwambiri kapena pamaso pa othandizira monga agalu. Ma gels awonetsera ma viscoelastic ndipo amagwiritsidwa ntchito pogwiritsa ntchito monga momwe amagwirira ntchito mankhwala osokoneza bongo, pomwe kutulutsa kosakanikirako kumafunikira.

Mitundu ya hpmc ya hpmc, kuphatikiza mamasukidwe, thixotropy, kudalira kwamchere, kudalira kwamchere, kumapangitsa chidwi cha pamtunda, kusewera gawo lofunikira pakusankha momwe amagwirira ntchito pamafashoni osiyanasiyana. Kuzindikira ndi kuwongolera zinthuzi ndikofunikira kuti mutsanzire kapangidwe kake ndi kukonza zinthu zochokera kwa HPMC.
