Zvivakwa zveHPMC (hydroxyprusll methyl cellulose)

Hydroxyprishpyl methylcellose (HPMC) ndeye semi-synthetic polymer inotorwa kubva ku cellulose. Iyo ine zvivakwa zvakati wandei izvo zvinoita kuti ibatsire mune dzakasiyana siyana maindasitiri. Heano mamwe mimwe midziyo yeHPMC:

1. Solubl Solubility: HPMC inonyungudika mumvura inotonhora, kugadzira yakajeka, viscous mhinduro. Iyo Solubility inosiyana zvichienderana neiyo degree rekutsiva
2. Kuumbwa kwaHupcility: HPMC inoratidzira yakanaka yekukwana kugadzikana, kuchengeta zvivakwa zvayo pamusoro pehuremu hwakawanda hwekupisa. Zvinogona kutsungirira mamiriro ekugadzirisa akasangana nemumaindasitiri akasiyana-siyana, kusanganisira mishonga yekuvaka uye yekuvaka.
3. Film Ford: HPMC ine mafirimu-ekugadzira mafirimu, achibvumira kuti aumbe mafirimu akajeka uye anochinjika pakuomesa. Ichi chivakwa chinobatsira mumishonga yemishonga, uko HPMC inoshandiswa kujasi mahwendefa uye magiramu ekudzorwa zvinodzorwa zvinodhaka.
4. Kukoshesa kugona: HPMC zviito seMubatanidzwa wakakura mumvura mhinduro, inowedzera viscosity uye inovandudza chimiro chemafambiro. Zvinowanzoshandiswa mumapendi, zvinonamatira, zino, uye zvigadzirwa zvekudya kuti uwane kuwirirana kwaunoda.
5. Rheology shanduko: Hpmc inoshanda seye roMology modifier, ichipesvedzera maitiro ekuyerera uye zvevasangano emhinduro. Zvinoratidza maitiro epseudoplastic, zvinoreva viscosity inoderera pasi peShear kushushikana, kubvumira kuve nyore kushandisa uye kupararira.
6. Kuchengeta kwemvura: HPMC ine yakanakisa mvura yekuchengetedza mari, ichibatsira kudzivirira kurasikirwa kunonyorovesa mumamiriro ezvinhu. Ichi chivakwa chinonyanya kubatsira pazvinhu zvekuvaka senge motsa uye maHPMC inovandudza kushanda uye kushamisika.
7. Kugadzikana kwemakemikari: HPMC inogadziriswa nemakemikari pasi pehuremu hwakawanda hwePP mamiriro, zvichiita kuti zvive zvakakodzera kushandiswa mune dzakasiyana siyana. Iyo inopesana nekurovera microbial kusvibiswa uye hakusi kwekukosha kwakanyanya kwemakemikari pasi pemamiriro ezvinhu ekuchengetedza.
8. Kuenderana: HPMC inoenderana neyakawandisa yezvimwe zvinhu, kusanganisira polymers, surfacts, uye yekuwedzera. Inogona kuve inoiswa nyore nyore kuita mafambiro pasina kukonzera zvinoenderana nenyaya kana kukanganisa mashandiro emamwe mashandiro.
9. Nonition Chando: HPMC ndeye Polymer Polymer, zvinoreva kuti haina kutakura mhosva yemagetsi mune mhinduro. Ichi chivakwa chinobatsira kune yayo uye kuwirirana nemhando dzakasiyana dzezvimiro uye zvinongedzo.

HydroxyPropyl methylcellose (HPMC) ine musanganiswa wakasarudzika wezvivakwa zvinoita kuti ive yakakosha maindasitiri akasiyana. Yayo solubility, inogadzikana yekudzikama, yefirimu yekugadzira, inokonzeresa nzvimbo, kuchengetwa kwemvura, kudzikama kwemamwe, uye kuenderana nezvimwe zvinhu zvinoita kuti zviite kuti zviite zvakaringana zvekushandisa.
