Hydroxypypyl methylcellulose moder

Hydroxypropyl methylcellulose (hpmc)Ndi gawo losiyanasiyana lomwe limagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo za mankhwala osokoneza bongo, chakudya, zodzoladzola, ndi zomanga. Katundu wake ndi mapulogalamu ake amasiyanasiyana kutengera kapangidwe kake, womwe ukhoza kusinthidwa kuti ugwirizane ndi zosowa zapadera.

Kapangidwe ka mankhwala:

HPMC imachokera ku cellulose, polymer wachilengedwe amapezeka muzomera.
Ma hydroxypyl ndi methyl ophatikizidwa amaphatikizidwa ndi magulu a hydroxyl a msana wa m'kompyuta.
Chiwerengero cha magawo awa chimatsimikizira katundu wa HPMC, monga kusumuli, khwala, ndi luso la mafilimu.

Digiri yokhazikika (DS):

DS amatanthauza kuchuluka kwa magulu am'magulu am'magulu amtundu wa glucose mu msana wakubwerera.
Makhalidwe apamwamba a DS DS amabwera chifukwa cha kuchuluka kwa hydrophilicity, kusungunuka, ndi mfuti.
DS HPMC imakhazikika kwambiri ndipo ili ndi chinyontho chovuta, ndikupanga kukhala koyenera kugwiritsa ntchito zomanga.

Kulemera kwa maselo (MW):

Kulemera molecular kumakhudza mafakisoni, luso lopanga mafilimu, komanso mphamvu zamakina.
HPMC yolemera yolemera imakhala ndi mafayilo apamwamba komanso katundu wabwino wopanga mafilimu, ndikupanga kukhala koyenera kugwiritsa ntchito mankhwala othandiza.
Kuchepetsa kwapang'onopang'ono kwa thupi kumayesedwa chifukwa chogwiritsa ntchito komwe kumachepetsa mafakisoni komanso kufalikira mwachangu.

Kukula kwa tinthu:

Kukula kwa tinthu kumapangitsa ufa woyenda, kusungunuka mosavuta, ndi kufananako.
Kukula Kwabwino Kukula kwa HPMC kumabala pafupipafupi m'matumbidwe am'madzi, kumapangitsa kuthamanga kwa hydration ndi gel.
Tinthu tating'onoting'ono tambiri titha kupereka katundu wabwino wotsika mu zosakaniza zouma koma zimafunikira nthawi yayitali.

Kutentha Kwawo:

Kutentha kwa mikate kumatanthauza kutentha komwe HPMC kumatheratu kwa gawo kuchokera pa yankho ku yankho ku yankho ku yankho la gel.
Magawo apamwamba kwambiri ndi zolemera kwa maonjetsani nthawi zambiri zimabweretsa kutentha kwamphamvu.
Kuzindikira kutentha kwa mpweya ndikofunikira pakupanga makina oletsa kuperekedwera mankhwala omasulira komanso popanga ma gels ogwiritsira ntchito zapamwamba.

Katundu wa mafuta:

Kukhazikika kwamafuta ndikofunikira pakugwiritsa ntchito komwe HPMC imagwirizanitsidwa pokonzekera kapena kusungira.
DS HPMC ikhoza kuwonetsa kukhazikika kwa matenthedwe chifukwa cha kukhalapo kwa malo ogwirira ntchito.
Njira zosinthira monga njira zosiyanirana ndi ma caloring calorimetry (dsc) ndi thermagramvimetric percisis (tga) imagwiritsidwa ntchito poyesa njira yofananira.

Kusungunuka ndi zotupa zotupa:

Kusungunuka ndi kutupa kumadalira ds, kunenepa kwambiri, ndi kutentha.
DS DS ndi zolemera zolemera zolemera nthawi zambiri zimawonetsa kususuka kwambiri ndikutupa m'madzi.
Kumvetsetsa zotupa ndi kutupa kumayambitsa zovuta pakupanga mankhwala osokoneza bongo a mankhwala omasulira ndikupanga ma hydrogeels a biomedal ntchito.

Zolengedwa:

Mphamvu monga mafakisoni, ku Sheretion Shereming, ndi ma visa ndikofunikira mu ntchito zosiyanasiyana.
HpmcMayankho a PSeudoplastic, komwe akuwoneka bwino ndikuwonjezeka.
Mitundu ya matenda a hpmc imathandizira kusamalira kwake m'mafakitale monga chakudya, zodzoladzola, ndi mankhwala.

Kusiyana pakati pa mitundu yosiyanasiyana ya HPMC tsinde kuchokera kusiyanasiyana pakapangidwe ka mankhwala, kulemera kwa ma celecular, kuwonjezeka kwa mpweya, kusungunuka, machitidwe, ndi zotupa. Kumvetsetsa izi ndikofunikira posankha kusiyanasiyana koyenera kwa HPMC kaupangiri, kuyambira mankhwala opanga mankhwala kumayiko omanga.
