Hydroxypropyl Methylcellulose (HPMC)ipolymer inonyungudika mumvura inowanzoshandiswa mumaindasitiri emishonga, chikafu, zvizoro, uye kuvaka. Hunyoro hweHPMC hune basa guru mukugadzirisa nekugadzikana kwayo. Hunokanganisa hunhu hwerheological, kunyungudika, uye hupenyu hwesherufu yezvinhu. Kunzwisisa hunyoro hwayo kwakakosha pakugadzirwa kwayo, kuchengetwa kwayo, uye kushandiswa kwayo kwekupedzisira.
Hunyoro hweHPMC
Hunyoro hweAnxinCel®HPMC hunowanzo tsanangurwa nemamiriro ekushanda uye giredhi chaiyo yepolymer inoshandiswa. Hunyoro hwemvura hunogona kusiyana zvichienderana nezvinhu zvakabikwa, mamiriro ekuchengetedza, uye maitiro ekuomesa. Hunowanzo ratidzwa sechikamu chehuremu hwemuenzaniso usati waomeswa uye mushure mekuomeswa. Pakushandiswa kwemaindasitiri, hunyoro hwemvura hwakakosha, sezvo hunyoro hwakawandisa hunogona kukonzera kuora, kuungana, kana kudzikira kwekushanda kweHPMC.
Hunyoro hweHPMC hunogona kubva pa5% kusvika 12%, kunyange hazvo hunyoro hwakajairika huri pakati pe7% ne10%. Hunyoro hunogona kuonekwa nekuomesa sample patembiricha chaiyo (semuenzaniso, 105°C) kusvika yasvika pahuremu hwakaenzana. Musiyano wehuremu usati waomeswa uye mushure mekuomeswa unomiririra hunyoro.
Zvinhu Zvinokanganisa Hunyoro muHPMC
Zvinhu zvakasiyana-siyana zvinogona kukanganisa hunyoro hweHPMC:
Mamiriro eKunyorova uye Kuchengeta:
Hunyoro hwakawanda kana mamiriro ekuchengetedza asina kunaka zvinogona kuwedzera hunyoro hweHPMC.
HPMC inopenya, zvichireva kuti inowanzo tora hunyoro kubva mumhepo yakapoteredza.
Kurongedza nekuvhara chigadzirwa kunogona kuderedza kunyungudika kwemvura.
Mamiriro Ekugadzirisa:
Kupisa kwekuomesa uye nguva panguva yekugadzira zvinogona kukanganisa hunyoro hwekupedzisira.
Kuoma nekukurumidza kunogona kukonzera hunyoro hunoramba huripo, nepo kuoma zvishoma nezvishoma kunogona kukonzera hunyoro hwakawanda kuti hurambe huripo.
Giredhi reHPMC:
Mhando dzakasiyana dzeHPMC (semuenzaniso, kusviba kwakaderera, kusviba kwepakati, kana kusviba kwakanyanya) dzinogona kunge dziine hunyoro hwakasiyana zvishoma nekuda kwekusiyana kwemaumbirwo nemagadzirirwo emamorekuru.
Tsanangudzo dzeMutengesi:
Vatengesi vanogona kupa HPMC hunyoro hwakatarwa hunoenderana nezvinodiwa nemaindasitiri.
Hunyoro Hwakajairika hweHPMC neGiredhi
Hunyoro hweHPMC hunosiyana zvichienderana nerudzi rwemvura uye mashandisirwo ayo. Heino tafura inoratidza hunyoro hwemvura hwemhando dzakasiyana dzeHPMC.
| Giredhi reHPMC | Kusviba (cP) | Hunyoro (%) | Mashandisirwo |
| Kusviba Kwakaderera HPMC | 5 - 50 | 7 - 10 | Mishonga (mapiritsi, makapisi), zvizoro |
| Kusviba kwepakati HPMC | 100 - 400 | 8 - 10 | Mishonga (inodzorwa), chikafu, zvinonamira |
| HPMC Yakanyanya Kusviba | 500 - 2000 | 8 - 12 | Kuvaka (kwakavakirwa pasimende), chikafu (chinhu chinosimbisa kukora) |
| Mishonga yeHPMC | 100 - 4000 | 7 - 9 | Mapiritsi, macapsule coatings, gel formulations |
| HPMC Yegiredhi Rekudya | 50 - 500 | 7 - 10 | Kukora kwechikafu, emulsification, kuputira |
| Giredhi rekuvaka HPMC | 400 - 10000 | 8 - 12 | Dhaka, zvinonamira, mapurasita, misanganiswa yakaoma |
Kuedzwa uye Kuona Hunyoro Hwacho
Kune nzira dzakawanda dzekuziva hunyoro hweHPMC. Nzira mbiri dzinonyanya kushandiswa ndeidzi:
Nzira yeGravimetric (Kurasikirwa neKuomesa, LOD):
Iyi ndiyo nzira inonyanya kushandiswa pakuona hunyoro. Huremu hunozivikanwa hweHPMC hunoiswa muovheni inoomeswa pa105°C. Mushure menguva yakatarwa (inowanzova maawa maviri kusvika mana), sampuli inoyerwa zvakare. Musiyano wehuremu unopa hunyoro, hunoonekwa sechikamu chehuremu hwemuenzaniso wekutanga.
Kusarudzwa kwaKarl Fischer:
Nzira iyi yakarurama kupfuura LOD uye inosanganisira makemikari anoita kuti mvura ionekwe. Nzira iyi inowanzo shandiswa kana panodiwa kuyera hunyoro nemazvo.
Mhedzisiro yeHunyoro paZvivakwa zveHPMC
Hunyoro hweAnxinCel®HPMC hunokanganisa mashandiro ayo mukushandiswa kwakasiyana-siyana:
Kusviba:Hunyoro hunogona kukanganisa kusimba kwemhinduro dzeHPMC. Hunyoro hwakawanda hunogona kuwedzera kusimba mune mamwe mafomura, nepo hunyoro hushoma hunogona kukonzera kusimba kushoma.
Kunyunguduka:Kunyorova kwakawandisa kunogona kukonzera kuungana kana kudzikira kwekunyungudika kweHPMC mumvura, zvichiita kuti isashande zvakanaka kune mamwe mashandisirwo, akadai semaforoma ekuburitsa anodzorwa muindasitiri yemishonga.
Kugadzikana:HPMC inowanzo gadzikana mumamiriro ekunze akaoma, asi hunyoro hwakawanda hunogona kukonzera kukura kwehutachiona kana kuora kwemakemikari. Nekuda kweizvi, HPMC inowanzo chengetwa mumidziyo yakavharwa munzvimbo dzisina hunyoro hwakanyanya.
Hunyoro uye Kurongedza kweHPMC
Nekuda kwehunhu hweHPMC hwakapfava, kurongedza kwakakodzera kwakakosha kudzivirira kunyudzwa kwemvura mumhepo. HPMC inowanzo kuputirwa mumabhegi kana mumidziyo yakagadzirwa nezvinhu zvakaita sepolyethylene kana multi-layer laminates kuti idzivirire kubva muhunyoro. Kurongedza uku kunoita kuti hunyoro hurambe huri mukati mehuwandu hunodiwa panguva yekuchengetera nekutakura.
Kudzora Hunyoro Mukugadzirwa Kwezvinhu
Panguva yekugadzira HPMC, zvakakosha kutarisa nekudzora hunyoro hwemvura kuti chigadzirwa chirambe chakanaka. Izvi zvinogona kuitwa kuburikidza ne:
Maitiro Ekuomesa:HPMC inogona kuomeswa uchishandisa mhepo inopisa, vacuum drying, kana rotary dryer. Tembiricha uye nguva yekuomeswa zvinofanirwa kugadziriswa kuti zvisaomeswe zvakanyanya (hunyoro hwakawanda) uye kuomeswa zvakanyanya (izvo zvinogona kukonzera kuora kwekupisa).
Kudzora Zvakatipoteredza:Kuchengetedza nzvimbo inodzorwa ine hunyoro hushoma munzvimbo yekugadzira kwakakosha. Izvi zvinogona kusanganisira zvinobvisa hunyoro, mhepo inotonhodza, uye kushandisa masensa ehunyoro kutarisa mamiriro ekunze panguva yekugadzirisa.
Hunyoro hwe HPMCKazhinji inowira pakati pe7% kusvika 10%, kunyange zvazvo ichigona kusiyana zvichienderana nerudzi, kushandiswa, uye mamiriro ekuchengetwa. Hunyoro chinhu chakakosha chinokanganisa hunhu hwerheological, kunyunguduka, uye kugadzikana kweAnxinCel®HPMC. Vagadziri nevagadziri vemakemikoro vanofanirwa kudzora nekutarisa hunyoro nekungwarira kuti vaone kuti hunoshanda zvakanaka mukushandiswa kwavo.
