Hydroxypropylmethylcellulose (HPMC) ipolymer yakagadzirwa nekugadzirisa serurosi chaiyo. Iyo ine akasiyana ekushandiswa kwemaindasitiri mumishonga, chikafu, zvizorwa, uye kuvaka. HPMC is nonionic cellulose ether inonyungudika zviri nyore mumvura uye inogona kuumba yakajeka, viscous solution inoramba yakagadzikana pamusoro pehupamhi pH renji.
Zvimiro zveHPMC zvinosanganisira:
1. Mvura yakakwirira yekuchengetedza simba: HPMC inogona kutora mvura uye kuibata panzvimbo, zvichiita kuti ibatsire semukobvu, emulsifier, uye stabilizer mune zvakawanda zvinoshandiswa.
2. Zvakanaka zvekugadzira firimu: HPMC inogona kugadzira mafirimu akajeka ane simba rakanaka remagetsi. Izvi zvinobvumira kuti ishandiswe mukugadzirwa kwe capsules, machira uye zvimwe zvigadzirwa.
3. Kushanda kwepamusoro kwepamusoro: HPMC ine nzvimbo-inoshanda zvinhu, zvichiita kuti ishandiswe sechinhu chinonyorova uye chinopararira.
4. Kugadzikana kwakanaka kwekushisa: HPMC yakagadzikana pakupisa kwepamusoro uye inogona kushandiswa muzvikumbiro zvinoda kuita uku.
5. Kubata kwakanaka kune zvakasiyana-siyana: HPMC inogona kusungirirwa kune dzakawanda nzvimbo, zvichiita kuti zvive zvakakosha mukugadzirwa kwezvokunamatira uye kuvhara.
Iko kushandiswa kweHPMC mumaindasitiri akasiyana:
1. Mushonga: HPMC inoshandiswa zvakanyanya mukugadzirira kwemishonga sebhainda, disintegrant, uye viscosity regulator. Inowanikwa mumapiritsi, capsules uye liquid formulations.
2. Zvokudya: HPMC inoshandiswa sechikafu, stabilizer uye emulsifier muzvokudya. Inogona kushandiswa muzvigadzirwa senge ice cream, yoghurt uye saradhi madhirezi.
3. Zvizoro: HPMC inoshandiswa zvakanyanya muzvizoro sechinhu chakakora, emulsifier, uye firimu-forming agent. Inogona kushandiswa muzvigadzirwa zvakaita semafuta, lotions uye shampoos.
4. Kuvaka: HPMC chinhu chinokosha muzvinhu zvakawanda zvokuvakisa zvakadai sematairi anonamira, simende-based plasters uye madhaka. Inoshanda semugadziri wekuchengetedza mvura, inovandudza kushanda, uye inopa nani kunamatira uye shrinkage control.
HPMC industry reference ratio:
1. Kuchengetwa kwemvura: Mwero wekuchengetedza mvura yeHPMC inokosha parameter inotarisa kushanda kwayo semukobvu uye kunamatira. Iyo nzvimbo ine indasitiri yereferensi mareti e80-100%.
2. Viscosity: Viscosity ndiyo inokosha parameter pakusarudza HPMC yezvikumbiro zvakasiyana-siyana. Indasitiri retiosheni yeviscosity inotangira pa5,000 kusvika 150,000 mPa.s.
3. Methoxyl group content: The methoxyl group content of HPMC inokanganisa kunyungudika kwayo, viscosity uye bioavailability. Iyo indasitiri yereferensi reshiyo yemethoxy yemukati iri pakati pe19% ne30%.
4. Hydroxypropyl content: The hydroxypropyl content inobata solubility uye viscosity yeHPMC. Iyo indasitiri yerejisheni yehuwandu hwehydroxypropyl iri pakati pe4% ne12%.
HPMC i polymer inoshanda zvakasiyana ine akawanda maindasitiri ekushandisa. Hunhu hwayo hwakasiyana hunoita kuti ive yakakodzera kushandiswa mumishonga, chikafu, zvizoro uye kuvaka. Indasitiri reisheni yemarejimendi akasiyana-siyana anobatsira pakusarudza giredhi rakakodzera reHPMC kune chaiyo application.
