Kutonga mhando ye hydroxyprupyl methyl cellulose

Hydroxyprusyl methyl celler celler Zvishandiso zvaro zvakasiyana zvinobva pazvinhu zvaro zvakasarudzika, zvakadai sekugona kwemufirimu-kugadzira, kukonzeresa simba, zvinosunga zvivakwa, uye nekuchengetwa kwemvura. Unhu hweHPMC hwakakosha kuti uve nechokwadi chekubudirira uye kuchengetedzwa kwezvigadzirwa umo izvo zvinoshandiswa.

1.comemical Comosion:
Iyo yemakemikari kuumbwa kweHPMC kwakakosha kune hunhu hwayo. HPMC ndeyekuti inobviswa cellulose, yakagadziridzwa kuburikidza nehydroxyprupropropylation uye methylation maitiro. Dhigirii rekutsiva Yakakwira DS tsika dzinowanzoguma nekuwedzera mvura solubility uye yakadzikira kupisa tembiricha. Nyanzvi dzekuongorora dzakadai seNyukireya Magneti Resonance (NMR) Spectrarepy Resonance

2.kudenga.
Kuchena chinhu chinonetsa cheHPMC mhando. Kutsvagisa kunogona kukanganisa maitiro uye kugadzikana kwezvigadzirwa. Kuonekwa kwakajairika kunosanganisira zvakasara sol sol sol sol sol, uye microbial casingnts. Nzira dzakasiyana dzekuongorora dzakasiyana-siyana dzakakwirira-performancaphy

3.Molecular uremu:
Iyo smecular uremu hweHPMC inokanganisa zvivakwa zvayo zvivakwa, Solubility, uye kugona kwemafirimu. Yakakwira molecular uremu HPMC inowanzo kuratidzira viscosity yakakura uye simba remafirimu. Gel Permegraphy chromatography (GPC) ndeye nzira inoshandiswa zvakanyanya kwekusarudza iyo molecular uremu kugoverwa kweHPMC samples.

4.Vissity:
Viscosity iri parmeter yemhando yeHPMC, kunyanya mukushandisa senge mishonga yemishonga, kwainoita senge mumiririri wakakura. Iyo viscosity yeHPMC Solutions inokanganiswa nezvinhu zvakadai sekusvinura, tembiricha, uye shear rate. Nzira dzakasiyana-siyana dzisimasi dzeViscometric, kusanganisira kutenderera kwekutima tolcustry uye Capillary vinotenda, vanoshandirwa kuyera vhiza yeHPMC mhinduro pamamiriro ezvinhu akasiyana.

5.Ph uye Unyoro Zvemukati:
Iyo pH uye zvinyoro-nyoro zvemukati zveHPMC inogona kukanganisa kugadzikana kwayo uye kuenderana nezvimwe zvinoshandiswa mukuumbwa. Zvinyorwa zvekunyorova zvinonyanya kukosha seyakawandisa unyoro hunogona kutungamira mukukura kwemicrobial uye kusvibiswa kweHPMC. Karl Fischer titration inowanzoshandiswa kuona kuti inonyorova, nepo ph metres ishandirwi kuyera ph.

6.Parthi ukuru uye morphology:
Size Saizi uye morphology anotamba basa rakakosha muzvivakwa zveHPMC hpmc. Nhungamiro dzakadai seLaser difforction uye kuongorora Electron microscopy (sem) inoshandiswa kuratidza iyo size saizi yekugovera uye morphology yeHPMC zvikamu zveHPMC.

7.thermal zvivakwa:
Zvivakwa zvekupisa zvakadai segirazi tembiricha tembiricha Kusiyanisa kuongorora Calorimetry (DSC) uye thermogravimetric kuongorora (tga) zvinowanzoshandiswa kuongorora maitiro eHPMC samples.

8.Kura uye mafirimu ekuumbwa:
Zvekushandisa zvinoda kuumbwa maGel kana mafirimu ekuumbwa, iyo magetsi ekupisa uye mafirimu-ekugadzira mafirimu ekugadzira HPMC ane crucial mhando ma parmeter. Rheological zviyero uye miedzo yekugadzira mafirimu inoitwa kuti iongorore izvi zvivakwa pasi pemamiriro akakodzera.

Kuongorora mhando yeHydroxyPropyl methyl cellyl Cellyl Cellyl Cellyl Composition Maitiro akasiyana-siyana ekuongorora anoshandirwa kuongorora iyi paramita, inoona kuti HPMC inosangana nezvinotaurwa zvinodiwa kuti zviitwe zvekushandisa. Nekuchengeta zviyero zvepamusoro-zvemhando yepamusoro, HPMC Vagadziri vanogona kuve nechokwadi chekubudirira, kuchengeteka, uye kuita kwezvigadzirwa kupfuura maindasitiri akasiyana siyana.
