Pharmaceutical Grade HPMC

Pharmaceutical grade HPMCHydroxypropyl methylcellulose ndi yoyera kapena yamkaka yoyera, yopanda fungo, yopanda pake, ufa wa fibrous kapena granule, kuwonda pa kuyanika sikudutsa 10%, sungunuka m'madzi ozizira koma osati madzi otentha, pang'onopang'ono m'madzi otentha, kutupa, peptization, ndi kupanga viscous colloidal solution. , yomwe imakhala yankho ikakhazikika, ndipo imakhala gel ikatenthedwa. HPMC sisungunuka mu ethanol, chloroform ndi ether. Imasungunuka mu zosungunulira zosakanikirana za methanol ndi methyl chloride. Amasungunukanso mu zosungunulira zosakanikirana za acetone, methyl chloride ndi isopropanol ndi zosungunulira zina za organic. Njira yake yamadzimadzi imatha kulekerera mchere (njira yake ya colloidal siiwonongeka ndi mchere), ndipo pH ya 1% yamadzimadzi ndi 6-8. The molecular formula of HPMC ndi C8H15O8-(C10H18O6) -C815O, ndipo ma molecular molecular mass ndi pafupifupi 86,000.

Kugwiritsa ntchito

Mbali ndi Ubwino:

HPMC ali kwambiri kusungunuka madzi m'madzi ozizira. Ikhoza kusungunuka mu njira yowonekera ndikugwedeza pang'ono m'madzi ozizira. M'malo mwake, sichisungunuka m'madzi otentha kuposa 60℃ndipo akhoza kungotupa. Ndi non-ionic cellulose ether. Yankho lake liribe mtengo wa ionic, sichimagwirizanitsa ndi mchere wachitsulo kapena ma ionic organic compounds, ndipo sichichita ndi zipangizo zina panthawi yokonzekera; ali ndi anti-sensitivity amphamvu, ndipo pamene mlingo wa kulowetsedwa m'malo mwa maselo ukuwonjezeka, ake Ndiwogonjetsedwa ndi ziwengo komanso okhazikika; imakhalanso ndi vuto la metabolic. Monga chothandizira chamankhwala, sichimapangidwa ndi metabolized kapena kutengeka. Choncho, sizipereka kutentha kwa mankhwala ndi zakudya. Ndikalori wotsika, wopanda mchere, komanso wopanda mchere kwa odwala matenda ashuga. Matupi mankhwala ndi zakudya ndi applicability wapadera; imakhala yokhazikika kwa ma acid ndi alkalis, koma ngati mtengo wa PH umaposa 2 ~ 11 ndipo umakhudzidwa ndi kutentha kwapamwamba kapena uli ndi nthawi yayitali yosungirako, kukhuthala kwake kudzachepa; yankho lake lamadzimadzi limatha kupatsa ntchito Pamwamba, kuwonetsa kugwedezeka kwapang'onopang'ono komanso kusamvana kwapakati; ili ndi emulsification yothandiza mu machitidwe a magawo awiri, angagwiritsidwe ntchito ngati stabilizer yothandiza komanso colloid yoteteza; njira yake yamadzimadzi imakhala ndi zinthu zabwino kwambiri zopangira mafilimu, ndipo ndi piritsi ndi piritsi. Chophimba cha filimu chopangidwa ndi icho chimakhala ndi ubwino wa colorlessness ndi kulimba. Kuwonjezera glycerin kungathandizenso pulasitiki yake.
