HydroxyPropyl methylcellose (HPMC) ipurusi-soluble polymer commer inowanzo shandiswa mumishonga yemishonga, chikafu, zvekuvaka uye mamwe minda. Mhando yemhando yayo inobata zvakananga kuita uye kugadzikana kwechigadzirwa.
1. Kutaridzika uye ruvara
Chitarisiko uye ruvara nderekutanga nzira dzekuongorora mhando ye hydroxyprupylpropyl methylcellose. Mhando yepamusoro HPMC inowanzo kuve yakachena kana kuti isina-chena poda neyunifomu uye yakaomesesa chimiro. Ruvara harufanirwe kuve rwero, brown kana chero ruvara rwechirume, runogona kunge rwakakonzerwa nekuora kwakakonzerwa nekuzvidzora zvinhu zvisingaiti kana kuchengeterwa zvisina kufanira panguva yekugadzira. Kana iyo ruvara ruchizadza, zvinogona kuratidza kuti pane dambudziko ne batch yezvigadzirwa uye kumwe kuongorora kunodiwa.
2. Powder yezasi saizi yekugovera
Particle saizi kugoverwa ndechimwe chezvinhu zvakakosha mukuongorora kunaka kweHPMC. HPMC yemhando yakanaka kazhinji ine yunifomu yehukuru. Zvakakura kana zvidiki zvidiki zvidimbu zvinokanganisa iyo solubility uye mhedzisiro mune zvinoshanda zvinoshandiswa. Iyo size yehukuru inogona kuongororwa nekuvhara kana laser chidimbu chekuongorora. Zvakawanda zvakakura zvimedu zvinogona kutungamira kune zvisina kunaka solubility uye kukanganisa zvavakaita uye kusafanana. Maitiro akasiyana ekugeda anogona kushandiswa mukugadzira kudzora kugoverwa kwezvikamu kuti vave nechokwadi chekuti HPMC inogona kuita zvakanyatsogadzirirwa.
3. Solubility mvura uye mwero wekupaza
Iyo mvura solubility yeHPMC chiratidzo chakakosha chekuongorora kunaka kwayo. Yayo solubility inowanzo kukanganiswa neiyo molecular chimiro uye degree rekutsiva hydroxyprupyl uye methyl mapoka. Yakakwira-mhando HPMC inogona kunyungudika nekukurumidza mumvura kuti iite mhinduro yeruzivo uye yunifomu. Kuti uedze iyo solubility yemvura, imwe huwandu hweHPMC inogona kuwedzerwa nemvura, yakakurudzirwa pane imwe tembiricha, uye kumhanya kwayo kwekumhanya uye kufanana kwekunyungudika mushure mekunyungudika kunogona kucherechedzwa. Kana ikanyungudika zvishoma nezvishoma kana inoburitsa mapopoma insoluble, zvingave kuti iyo HPMC mhando isina kukodzera.
4. Viscosity bvunzo
Iyo viscosity yeHPMC iri kiyi yekuita chiratidzo chehunhu hwayo, kunyanya kana ichishandiswa seanoshandiswa seanoti, emulsifier kana gelling mumiririri. Viscosity inowanzoenderana neyekumusoro uremu uye degree rekutsiva hpmc. Viscosity yayo inogona kuedzwa neyekutenderera yekutenderera kana rheometer kuti uongorore zvivakwa zvayo zvimisikidzwa. Zvakakodzera, iyo viscosity yeHPMC inofanira kuve yakagadzikana mukati meimwe huwandu kuve nechokwadi chekuita kwayo mune dzakasiyana mashandisirwo.
Paunenge uchiedza zvavakaita, HPMC inofanira kunyungudutswa mune imwe pfungwa yemvura, tembiricha inofanira kuchinjwa, uye zvivakwa zvezvinyorwa zvemhinduro pane dzakasiyana siyana dzimba dzinofanirwa kuyerwa. Kana iyo viscosity isingaenzaniswi, inogona kukanganisa mashandiro eHPMC, kunyanya mukushandisa zvibodzwa zveViscossity.
5. Kutsunga kweDhigiri rekutsiva
Dhigirii rekutsiva Dhigirii rekutsiva zvakananga zvinobata zvakananga kuti solubility, viscosity uye zvimwe zvemuviri uye zvemakemikari zvivakwa. Nhungamiro dzakadai seinfrared spectroscopy (ftir) kana nyukireya magineti resonance
Kune yakakwirira-mhando HPMC, iyo degree rekutsiva rinofanira kunge riri mukati meiyo yakatarwa. Yakanyanya kukwirira kana kuderera kwazvo degree rekutsiva kunogona kukonzera kusagadzikana kuita uye kukanganisa mhando yechigadzirwa chekupedzisira. Semuenzaniso, yakanyanya kukwirisa methyl kutsiva kunogona kukanganisa simba rayo rekunyora, nepo rakadzika kwazvo substitution rinogona kukanganisa maitiro ayo akashata.
6. Kutsunga kwezvinhu zvinyoro-nyoro
Zvinyorwa zvekunyorova ndechimwe chezvinhu zvakakosha zvinokanganisa kunaka kweHPMC. Kunyanya kukwira zvinyoro-nyoro zvemukati zvinogona kukonzera chigadzirwa kune maune uye negglomerate, nekudaro zvichikanganisa mashandiro azvo. Zvemukati zvinyoro zvinowanzo kutsanangurwa nekuomesa kana Karl Fischer technation. Iyo yakanyorova yeiyo yepamusoro-mhando HPMC inowanzo kuve isingasviki 5% kuve nechokwadi chekuti kunaka kwayo hakuchinji panguva yekuchengetedza uye kushandiswa.
7. PH bvunzo
Iyo PH Kukosha kweHPMC Solution ndiyo zvakare yakakosha chiratidzo chehunhu hwayo. Mhinduro yeHPMC inofanirwa kuve neyakakurumbira pH kukosha, kazhinji pakati pe40 ne 8.0. Kunyanya acidic kana alkaline mhinduro inogona kukanganisa kugadzikana kwayo uye kushanda mukushandisa. Iyo PH kukosha kunogona kutsanangurwa nekuyera zvakananga iyo pH yemhinduro uchishandisa pH meter.
8. Microbiologicological Kuedzwa
HPMC ndeyemhando yepamusoro inowanzo shandiswa mune maindasitiri emishonga uye ezvekudya, uye kusvibiswa kwaro microbial kunoda kutarisisa kwakakosha. Microbial kusvibiswa kusingabatanidze kuchengetedzeka kwechigadzirwa, asi zvinogona zvakare kukonzera chigadzirwa kuti chisimbise kana kushatisa mukuita. Microbial kuyedzwa kunogona kuitwa netsika, PCR uye dzimwe nzira dzekuona kuti zviyero zveHPMC chasangana nezvinodiwa zvemitemo yakakodzera.
9. Thermogravimetric kuongorora (tga) uye kusiyanisa kuongorora calorimetry (DSC)
Kuongorora kweTremogravimetric (tga) uye kusiyanisa kuongorora calorimetry (DSC) kunogona kushandiswa kuti udzidze kugadzikana kweHPMC uye maitiro ayo echiedza panguva yekudziya. Nzira idzi dzinogona kuwana yakakosha data yakadai sekurasikirwa kwakawanda, yekunyungudika, uye girazi transition tembiricha yeHPMC pane dzakasiyana tembiricha kuti ubatsire kusarudza kana ichisangana chaiyo application.
10. Kutsunga kwe chloride yezvinyorwa
Kana HPMC ine yakawandisa chloride, ichakanganisa iyo solubility uye kugadzikana mukushandisa. Zvekuita chloride zvacho zvinogona kutsanangurwa nemurazvo wemoto kana itsikotometric titration. Iyo chloride yezvinyorwa zveHPMC ine hunhu hwakanaka inofanira kudzorwa mukati meimwe huwandu kuti uve nechokwadi chekuchengetedza kwayo uye kushanda.
Nzira dziri pamusoro dzinogona kungoongorora mhando ye hydroxyprupylculose, kusanganisira chitarisiko, solubility, deginity, degree rekutsiva uye zvimwe zvinhu uye zvimwe zvinhu. Zvinoshandiswa zvakasiyana zvine zvinodiwa zvakasiyana HPMC, saka kana uchitarisa kunaka kwayo, zvakakodzera kuitisa kuongororwa kwakazara mukubatanidzwa pamwe nezvinodiwa zveminda chaiyo yekushandisa. Iyi nzira dzekuyedza dzinogona kuve nechokwadi chekugadzikana, kushanda uye kuchengetedzeka kweHPMC zvigadzirwa, kupa vimbiso dzekushandisa kwavo kwakawanda.
