HydroxyPropyl methylcellose (HPMC) iPoliFunDental Polymer ane maindasitiri akasiyana-siyana senge mishonga yemishonga, etc. Heano kuongorora kwakadzika kweHPMC:
1. Hunhu hweHPMC:
Chemical dhizaini: HPMC inotorwa kubva kuCellulose, iyo yakasikwa yepanyama inowanikwa mune zvidyarwa. Iyo yakashongedzwa nemakemikari kugadzirisa cellulose ine profilyone oxide uye methyl chloride. Dhigirii rekutsiva kwehydroxyprusyl uye mapoka mapoka anotema zvivakwa zvaro.
Solubility: HPMC inonyungudika mumvura pamusoro peyakawedzera tembiricha. Solubility inotsamira pane iyo degree rekutsiva uye suremu hwemanyorerwe emapolymer. Yakakwira Substitution mazinga anotungamira kune kuwedzera mvura solubility.
Viscosity: HPMC inoratidza pseudoplastic kana shear-yakaonda maitiro, zvichireva kuti viscoity yayo inoderera pasi pekushushikana. Iyo viscosity yeHPMC Solutions inogona kugadziriswa nekugadzirisa paramita yakadai seyekuita sreek, degree rekutsiva, uye kusvinura.
Film Fomu: HPMC mafomu akajeka uye anochinja mafirimu kana akakandwa kubva pane mhinduro. Firimu zvivakwa zvinogona kugadziridzwa nekugadzirisa polymer yekusimbisa uye kuvapo kwepurasitiki.
Kugadzikana kweTermal: HPMC ine yakanaka yekudzikama kugadzikana, nekushambadzira kwechidhori kazhinji pamusoro pe200 ° C. Izvi zvinoita kuti zviite zvakakodzera mhando dzakasiyana dzekugadzirisa, kusanganisira kupisa rollt Extrusion uye jekiseni kuumbwa.
Hydrophicity: Nekuda kweiyo hydrophilic mamiriro, HPMC inogona kutora uye kuchengetedza mvura yakakura. Ichi chivakwa chinobatsira mukushandisa zvakadai sekutorwa-kusunungura zvinodhaka zvinodhaka uye seyemumiririri wakakura mune zvemvura.
Kuenderana: HPMC inoenderana nezvimwe zvinhu zvakasiyana siyana, kusanganisira vamwe polymers, mapurasitiki, uye anoshanda mishonga yemishonga (APIS). Uku kuwirirana kunobvumira kuomesa masisitimu kuti kuvezwa nezvinhu zvakarongeka.
Isiri-Ionic Properties: HPMC isisiri-Ionic polymer, zvinoreva kuti haina kutakura chero chipi zvacho chemagetsi. Ichi chivakwa chinodzikisira kutaurirana nemhando dzakabhadharwa muzvimiro uye dzinosimudzira kugadzikana kwayo mumhinduro.
2.HPMC inoshanda:
Binders: Muchiratidzo chehembe, HPMC zviito sedanda, kusimudzira kuderedza pakati pezvikamu uye kuwedzera simba rekusimba kwehwendefa. Izvo zvakare zvinobatsira mahwendefa disintegrato mushure mekugeza.
Firimu Coating: HPMC inowanzoshandiswa zvakanyanya sefirimu yekubatanidza mumirapini nemakapuru. Iyo inoumba yunifomu, inodzivirira yekuvhara iyo masks iyo kuravira uye kunhuhwirira kwemushonga, inosimudzira kugadzikana, uye inofambisa kumedza.
Yakaburitswa kuburitswa: HPMC inogona kushandiswa kudzora chiyero chekuburitsa chemishonga kubva kumishonga yemishonga yemishonga. Ne hydarthing kuumba gel layer, HPMC inogona kunonoka kuburitswa kwezvinodhaka uye kupa zvakaringana zvinogadzirisa mhedzisiro.
Viscosity Modifier: Mune masisitimu emvura, HPMC zviito seViscosity Modifier kana Thickener. Iyo inopa pseudoplastic maitiro ekuyerera, achivandudza kugadzikana uye kushanda kwekushandisa kwekuumbwa kwakadai semakiromita, lotions uye geri.
Kumisa Mumiriri: HPMC inoshandiswa kusimbisa kumiswa kwemisangano yezvinhu zvakasarudzika mune zvemvura mafomu. Iyo inodzivirira kugadzirisa nekuwedzera iyo visikoka yeiyo inoenderera chikamu uye kuvandudza tangi.
Emulsifier: Mune emulsion mafomu, HPMC inokanganisa iyo interface pakati pemafuta uye zvikamu zvemvura, kudzivirira chikamu chekupatsanurwa uye emulsization. Iyo inovandudza kugadzikana uye mararamiro erembera mune zvigadzirwa zvakadai semakiromita, mafuta ezino uye marara.
Hydrogel kuumbwa: HPMC inogona kuumba hydrogels kana hydrate, ichiita kuti ibatsire muvaraira madhiri, malents, uye masisitimu ekutengesa anodhaka. Aya mydrogels anopa nzvimbo inonyorovesa yekupora ronda uye inogona kutakurwa nezvinodhaka zvekutakura kwenzvimbo.
Akakora Agent: HPMC inowanzoshandiswa seyakaomerera mumiririri mune zvekudya zvekudya senge sosi, kupfeka uye madhiri. Iyo inopa chimiro chakanyatsojeka uye chinowedzera kuravira pasina kushandura flavour kana hutano.
Kuwedzera Kuvaka: Mune indasitiri yekuvaka, HPMC inoshandiswa seyemvura-yekuchengetedza mumiririri mumutengo wetsiva-bundu uye plasters. Inovandudza basa rekushanda, kuderedza, uye kuderedza kupaza nekudzora mvura yekubuda kwemvura.
Surch modifier: HPMC inogona kugadzirisa nzvimbo dzepasi pevhu rakasimba sepepa, machira uye ceramics. Iyo inovandudza kudhinda, kuderedza uye zvipingamupinyi zvematombo uye mafirimu.
Hydroxypronylmethylcellose (HPMC) inzira inoverengeka polymer ine dzakasiyana siyana zvivakwa uye mabasa. Yayo solubility, viscosity, firimu-inogadzira kugona uye kuwirirana kunoita kuti ive isina kukosha mune yakawanda application maindasitiri. Kubva pamishonga yekuvakwa, chikafu kune cosmetics, HPMC inoenderera mberi nekutamba basa rakakosha mukuvandudza kuita kwechigadzirwa uye mhando. Sezvo kutsvagisa uye tekinoroji kufambira mberi, zvinoshandiswa uye zvinoshandiswa neHPMC zvinogona kuwedzera kuwedzera, kutyaira mukugadzira mukugadzira magadzirirwo echigadzirwa uye zvigadzirwa zvechigadzirwa.
