Hydroxypropylmethylcellulose (HPMC) ikamu rinoshandiswa zvakanyanya rine huwandu hwakawanda hwemaindasitiri, kutengeserana, uye hutano hwehutano. HPMC chinhu chisinganhuhwi, chisingaravike, uye chisina chepfu chinobva muselulosi. Mushonga unonyungudika nemvura unoshandiswa mune zvakasiyana siyana zvekudya, zvekuzora, zvinodhaka, nemishonga. HPMC inozivikanwa nekugona kwayo kugadzira firimu, inonamira zvivakwa uye simba rekuchengetedza mvura. Iyo inozivikanwa zvakare nekunaka kwayo viscosity, kugadzikana uye kuenderana nezvinhu zvakasiyana.
Mhando dzeHPMC:
Kune akati wandei marudzi eHPMC pamusika, imwe neimwe iine yakasarudzika yemuviri uye makemikari zvivakwa. Heano mamwe marudzi akajairika eHPMC:
1. Low viscosity HPMC:
Low viscosity HPMC inoratidzirwa nekuderera kwema molecular uremu uye yakaderera dhigirii yekutsiva. Nekuda kwehunhu hwayo hwekusunga, inowanzoshandiswa sebhainda uye disintegrant mumapiritsi.
2. Medium viscosity HPMC:
Medium viscosity HPMC ine yepakati molecular uremu uye dhigirii yokutsiva. Inowanzoshandiswa kudzikamisa emulsions, kumiswa uye furo muindasitiri yechikafu nechinwiwa.
3. High viscosity HPMC:
High viscosity HPMC inoratidzirwa nehupamhi hwema molecular uremu uye yakakwirira dhigirii yekutsiva. Iyo inowanzoshandiswa seyakakora uye gelling mumiriri mune zvekudya uye zvekuzora maindasitiri.
4. Surface kurapwa HPMC:
Surface yakarapwa HPMC inorapwa nemakemikari akasiyana siyana kugadzirisa pamusoro penzvimbo yayo. Inowanzoshandiswa sechinhu chinowedzera muindasitiri yekuvaka kuvandudza zvimiro zvesimende-yakavakirwa zvinhu.
Zvakanakira zveHPMC:
HPMC inounza akawanda mabhenefiti kumaindasitiri akasiyana. Heano mamwe mabhenefiti anogona kuitika eHPMC:
1. Yakachengeteka uye isina chepfu:
Imwe yemabhenefiti makuru eHPMC kuchengetedzwa kwayo uye kusaita huturu. HPMC inotorwa kubva ku cellulose, musanganiswa wechisikigo. Iyo hainawo kushungurudza ganda, maziso uye mucous membranes, zvichiita kuti ive chinhu chakachengeteka mune zvakasiyana-siyana zvezvigadzirwa.
2. Kunyungudika kwemvura:
HPMC inonyanya kunyungudika nemvura, zvichiita kuti ive chinhu chakanakisa chezvigadzirwa zvakasiyana-siyana zvinoda kuchengetwa kwemvura uye kunamatira. Inowanzoshandiswa sebhainda uye disintegrant mumaindasitiri ezvekudya nemishonga.
3. Kugona kugadzira firimu:
HPMC ine hunyanzvi hwekugadzira firimu, zvichiita kuti ive chinhu chakanakisa chezvakasiyana zvigadzirwa zvinoda machira ekudzivirira. Inowanzoshandiswa muindasitiri yemishonga yekuputira mahwendefa uye capsules.
4. Viscosity uye thickening zvivakwa:
HPMC ine viscosity yakanakisa uye kukora zvivakwa, zvichiita kuti ive chinhu chakanakisa chezvigadzirwa zvakasiyana-siyana zvinoda kukora, kutsetseka kwemavara. Inowanzoshandiswa mumaindasitiri ezvekudya uye zvekuzora kukora sosi uye lotions.
5. Kugadzikana uye kuenderana:
HPMC ine kugadzikana kwakanyanya uye kuenderana nezvinhu zvakasiyana, zvichiita kuti ive chinhu chakanakisa muzvigadzirwa zvakasiyana-siyana zvinoda kugadzikana uye kuenderana. Inowanzoshandiswa muindasitiri yemishonga kudzikamisa kugadzirwa kwemishonga.
HPMC musanganiswa unoshanda unounza akawanda mabhenefiti kumaindasitiri akasiyana anosanganisira chikafu, zvekuzora nemishonga. Hunhu hwayo hwakasiyana hwemuviri nemakemikari hunoita kuti ive chinhu chakanakisa muzvigadzirwa zvakasiyana siyana, zvinosanganisira mabhainda, disintegrants, emulsions, suspending agents, foams, thickeners, gelling agents, uye vanogadzira mafirimu. HPMC zvakare yakachengeteka uye isiri-chepfu, zvichiita kuti ive chinhu chakanakisa muzvigadzirwa zvakasiyana-siyana zvinoda kuchengetedzwa uye zvisiri muchetura. Mhando dzakasiyana dzeHPMC dziripo pamusika dzinopa maindasitiri akasiyana siyana sarudzo dzekusarudza kubva maererano nezvavanoda uye zvavanoda.
