Hydroxypropyl methylcellulose (HPMC) haisi plasticizer mupfungwa yechinyakare. Icho chinobva kune cellulose chinowanzo shandiswa mumaindasitiri emishonga, chikafu, kuvaka uye ega ega. Kunyange zvisingaite semapurasitiki anoshandiswa mumapolymers, inoratidza zvimwe zvimiro zvinogona kukwikwidza mhedzisiro yepurasitiki mune mamwe maapplication.
Kuti tiongorore zvizere musoro weHPMC nebasa rayo mumaindasitiri akasiyana, tinogona kunyura muchimiro chayo chemakemikari, zvivakwa, mashandisiro, uye zvingangove zvakanakira uye zvazvakaipira. Kunzwisisa kwakazara kweHPMC kunopa nzwisiso mumashandisirwo ayo akasiyana uye nei ichionekwa sechinhu chakakosha mukugadzira kwakawanda.
Kemikari chimiro uye zvivakwa zveHPMC
Kemikari chimiro:
HPMC ndeye semi-synthetic polymer inotorwa kubva ku cellulose, yakasikwa polima inowanikwa muchirimwa sero madziro. Hydroxypropyl uye methyl mapoka anounzwa kuburikidza nekugadziriswa kwemakemikari. Ichi chigadziriso chinoshandura chimiro chemuviri uye chemakemikari zvimiro zve cellulose, zvichikonzera makomisheni ane mashandiro ekuwedzera.
chimiro:
Hydrophilic: HPMC inonyungudika mumvura uye yakanyanya hygroscopic, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekugadzira zvinoda kuchengetwa kwemvura kana kudzora kusunungurwa.
Firimu-kuumba: Iine firimu-inogadzira zvinhu zvinoumba firimu rinodzivirira kana rinoshandiswa pamusoro pepamusoro, zvichiita kuti rive rakakosha mukuputira kwemishonga uye zvinhu zvekuvaka.
Thickening agent: HPMC inowanzo shandiswa sechinhu chinokobvuta mumhinduro dzine mvura. Viscosity yaro inowedzera nekufungisisa, ichibvumira kutonga kwekuenderana kwekuumbwa kwemvura.
Tembiricha senitivity: Mamwe mamakisi eHPMC anodzoreredzwa nemoto, zvichireva kuti vanogona kuchinjika chikamu chekuchinja nekuchinja kwekushisa.
Kushandiswa kweHPMC mumaindasitiri akasiyana
1. Indasitiri yemishonga:
Tablet Coating: HPMC inowanzoshandiswa sechinhu chekuputira mahwendefa muindasitiri yemishonga. Inopa dura rekudzivirira, inodzora kuburitswa kwezvinodhaka, uye inovandudza kutaridzika kwehwendefa.
Ophthalmic Solutions: Mumadonhwe eziso uye ophthalmic mhinduro, HPMC inogona kuwedzera viscosity uye inonatsiridza kuchengetedza nguva pane yemaziso.
2. Indasitiri yezvekudya:
Thickening agent: HPMC inoshandiswa seyakakora mumiriri mune dzakasiyana siyana zvigadzirwa zvekudya, zvinosanganisira sosi, soups uye zvigadzirwa zvemukaka.
Emulsifier: Mune mamwe maapplication echikafu, HPMC inogona kuita senge emulsifier, ichivandudza kugadzikana kweiyo emulsion.
3. Indasitiri yekuvaka:
Tile Adhesives: Kuwedzerwa kweHPMC kumatairi anonamira kunovandudza kushanda, kuchengetedza mvura uye kusimba kwechisungo.
Madhiri uye Mapurasita: Anoshandiswa mukuvaka zvinhu zvakaita sedhaka nemapurasita kuwedzera kunamira uye kushanda.
4. Zvigadzirwa zvekuchengeta wega:
Topical formulations: Mumafuta, lotions uye mamwe maumbirwo epamusoro, HPMC inobatsira kuvandudza magadzirirwo, kugadzikana uye kunzwa kweganda kwechigadzirwa.
Zvigadzirwa Zvekuchengeta Bvudzi: HPMC inowanikwa mune zvimwe zvigadzirwa zvekuchengeta bvudzi nekuda kweiyo firimu-kuumba uye kugadzirisa zvivakwa.
Zvakanakira uye Zvakaipa zveHPMC
mukana:
Biocompatibility: HPMC inowanzoonekwa yakachengeteka kuti ishandiswe nevanhu uye inoshandiswa zvakanyanya mumishonga uye chikafu chekushandisa.
Versatility: Iine zvakasiyana-siyana zvezvivakwa uye yakakodzera kune akasiyana maindasitiri uye magadzirirwo.
Kuchengeta Mvura: Iyo hydrophilic chimiro cheHPMC inobatsira mukuchengetedza mvura, iyo inogona kubatsira mune mamwe maapplication.
kukanganisa:
Mutengo: HPMC inogona kudhura kana ichienzaniswa nezvimwe zvinowedzera.
Temperature Sensitivity: Nekuda kwekudzorereka kwemamwe mamakisi eHPMC, mamwe magadzirirwo anogona kukanganiswa nekuchinja kwekushisa.
mukupedzisa
Kunyangwe HPMC isiri plasticizer mupfungwa yechinyakare, yakasarudzika zvimiro inoita kuti ive chinhu chakakosha mumaindasitiri akasiyana. Iyo inoratidza kuita kwayo kwakasiyana-siyana seyaimbova firimu, thickener uye mvura inochengetedza mumiriri mumishonga, chikafu, kuvaka uye kuchengetedza munhu. Kunzwisisa chimiro chemakemikari, zvivakwa, uye mashandisirwo eHPMC kwakakosha kune vanogadzira uye vaongorori vari kutsvaga kukwirisa maumbirwo kuti asangane nezvinodiwa chaizvo. Zvakanakira biocompatibility uye kuita zvakasiyana-siyana zvinodarika zvipingamupinyi zvingangoitika, zvichiita kuti HPMC ive sarudzo yakakurumbira mumaindasitiri mazhinji.
