Pharmaceutical grade HPMC

Pharmaceutical grade HPMC

Pharmaceutical grade HPMC Hydroxypropyl methylcellulose ndi yoyera kapena yamkaka yoyera, yopanda fungo, yopanda kukoma, ufa wonyezimira kapena granule, kuwonda pa kuyanika sikudutsa 10%, kusungunuka m'madzi ozizira koma osati madzi otentha, pang'onopang'ono m'madzi otentha Kutupa, peptization, ndi kupanga viscous colloidal solution, yomwe imakhala yankho itakhazikika, 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.

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, imakhala yosasungunuka m'madzi otentha kuposa 60 ℃ ndipo imatha kutupa. 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 yosungirako nthawi yayitali, kukhuthala kwake kudzachepa; yankho lake lamadzimadzi limatha kupereka ntchito za 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.

 

Kupaka

Kunyamula kokhazikika ndi 25kg / Fibre ng'oma 

20'FCL: matani 9 okhala ndi palletized; 10 matani osasinthika.

40'FCL: matani 18 okhala ndi palletized; Matani 20 opanda pallet.

 

Posungira:

Sungani pamalo ozizira, owuma osapitirira 30 ° C ndi kutetezedwa ku chinyezi ndi kukanikiza, popeza katunduyo ndi thermoplastic, nthawi yosungira sikuyenera kupitirira miyezi 36.

                                                                          

Zolemba pachitetezo:                                                                         

Zomwe zili pamwambazi zikugwirizana ndi zomwe timadziwa, koma musamatsutse makasitomala kuti aziyang'ana zonse mwamsanga mutalandira. Kuti mupewe kupangidwa kosiyanasiyana ndi zida zosiyanasiyana, chonde yesaninso zambiri musanagwiritse ntchito.
