Hydroxypropyl methyl cellulose yamavuto wamba

Hydroxypropyl methylcellulose (hpmc)ndi polima wosiyanasiyana womwe umapeza mapulogalamu m'mafakitale osiyanasiyana monga mankhwala opangira mankhwala, zodzoladzola, chakudya, ndi zomanga. Ngakhale anali osiyanasiyana, pali zovuta zingapo zokhudzana ndi ogwiritsa ntchito zomwe ogwiritsa ntchito angakumane nazo.

Kusauka kosauka: Vuto limodzi lodziwika ndi HPMC ndi kusautsika kwake osauka m'madzi ozizira. Izi zitha kubweretsa zovuta pakupanga mayankho, makamaka pamene kufalikira kwamphamvu ndikofunikira. Kuti muthane ndi vutoli, njira zina zimaphatikizapo kusachitatsa, pogwiritsa ntchito madzi ofunda, kapena kugwiritsa ntchito mankhwalawa kuti apititse patsogolo kusungunuka.

Kusiyana kwa ma virus: Kutulutsa kwa masinthidwe a HPMC kumatha kukhala yosiyanasiyana chifukwa cha kutentha monga kutentha, Ph, kumeta ubweya, ndi polymer ndende. Makulidwe osagwirizana atha kusokoneza magwiridwe antchito, zomwe zimayambitsa mavuto monga mtundu wosauka kapena wogwiritsa ntchito mankhwala osokoneza bongo pakugwiritsa ntchito mankhwala. Opanga amafunika kusamala modekha kuti achepetse kusintha kwa magazi.

Hygroscopic chilengedwe: hpmc imakhala ndi chizolowezi chotenga chinyezi kuchokera ku chilengedwe, chomwe chimatha kusintha zopanga zake ndikuyambitsa kapena kudula mu ufa wowuma. Kuti muchepetse vutoli, malo osungirako osungira, monga chinyezi chotsika ndi chinyezi-chonyowa, ndizofunikira.

Khalidwe lowopsa: M'mapangidwe ena, hpmc amatha kuwonetsa zoopsa, makamaka m'malo okhazikika kapena pamaso pa ma iyo. Ngakhale kuphatikiza kungakhale kofunikira pakugwiritsa ntchito monga njira zoperekera mankhwala osokoneza bongo, zitha kutsogolera kukonza zovuta kapena kapangidwe kosasintha mu zinthu zina. Kuzindikira zinthu zomwe zimapangitsa kuti Gael mapangidwe azikhala ofunikira pakuwongolera ntchito.

Nkhani zogwirizana: hpmc sizingakhale zogwirizana ndi zosakaniza zina kapena zowonjezera zomwe zimagwiritsidwa ntchito popanga. Kusagwirizana kungaoneke ngati gawo la gawo la gawo, mpweya, kapena kusintha kwa ma vistoni, omwe angalepheretse kukhazikika kwa malonda ndi kufunikira kwake. Kuyesa kwa kuphatikizika kuyenera kuchitidwa kuti azindikire ndikuthana ndi mavuto omwe akupanga pakupanga chitukuko.

Shear Shereght: HPMC mayankho a HPMC nthawi zambiri amawonetsa machitidwe owoneka bwino, kutanthauza kuti ma viscy awo amachepetsa nkhawa. Pomwe katunduyu amatha kukhala wopindulitsa pakugwiritsa ntchito ndi zomatira, mwina zimabweretsa zovuta pakukonzekera kapena kugwiritsa ntchito, makamaka mu machitidwe ofunikira mavidiyo. Makhalidwe oyenera a hphilogical ndikofunikira kuti athetse magwiridwe antchito.

Kuwonongeka kwa mafuta: Kutentha kwambiri kumatha kuyambitsa kuchepa kwa magetsi kwa HPMC, kumapangitsa kuti kuchepetsedwa kwa mafayilo, kusintha kwa kulemera kwa mapangidwe, kapena kapangidwe kazinthu zowonongeka. Kukhazikika kwamafuta ndikuganizira mozama panthawi yosungirako panthawi yosungirako nthawi yosungirako, ndipo opanga ayenera kuwongolera kuwonekera kutentha kuti achepetse kuwonongeka ndikusungabe mtundu.

Kutsatira kwa ulamuliro: Kutengera zomwe mukufuna kugwiritsa ntchito ndi malowo, zinthu zina za HPROg zitha kukhala zogwirizana ndi zofunikira zowongolera komanso miyezo yolamulira, chiyero, ndi kulembera. Kuonetsetsa kuti kutsatira malamulo oyenera ndikofunikira kuvomerezedwa pamsika ndi kutsatira malamulo.

pamenehydroxypypyl methylcelluloseAmapereka zambiri monga polima, ogwiritsa ntchito amatha kukumana ndi mavuto osiyanasiyana okhudzana ndi kusungunuka, ma hygcroscopicity, kukhazikika, kukhazikika, komanso kukhazikika kwa matempha. Kuthana ndi mavuto omwewa kumafuna kumvetsetsa bwino kwa kapangidwe ka polima, kapangidwe kazinthu zosiyanasiyana, komanso zochitika zosintha, pamodzi ndi njira zoyenera zosokoneza zomwe zimagwirizanitsidwa pamapulogalamu enaake.
