HydroxyPropyl methylcellose (HPMC) ndeyekuchinja kwakasiyana-siyana kwakashandiswa zvakanyanya maindasitiri akasiyana siyana nekuda kwezvivakwa zvaro zvakasarudzika. Ichi chinyorwa chinopera mune zvinangwa zveHPMC, kuongorora chimiro chayo chemakemikari, zvivakwa, mabasa, uye zvinoshandiswa zvakasiyana. Kubva pamishonga yekuvakwa, zvigadzirwa zvekudya kune zvinhu zvega zvega, HPMC inoita basa rekutarisirwa, kuratidza kukosha kwayo mukusimudzira razvino uye kwechigadzirwa.
HydroxyPropyl methylcellose (HPMC) ndeyeMakero akagadziridzwa cellulose anowana kushandiswa kwakanyanya mumaindasitiri ekubva kune mishonga yekuvakwa, chikafu, uye hanya. Zvivakwa zvaro zvakasarudzika zvinoita kuti zvive zvakakosha mune dzakasiyana-siyana zvikumbiro, zvichikonzera kugadzikana, viscosity, uye kuita kwezvinhu zvakawanda.
1.chemical chimiro uye zvivakwa
HPMC iri yakanyorwa kuburikidza nekuita kweAlkali Cellalose ne methyl chloride uye inokonzerwa nekutsiva kwemapoka eHydroxyl muCellulose Caxulose neHydroxypruppropyl uye mapoka emhando. Uku kushandurwa kunopa zvivakwa zvakasarudzika kuHPMC, kusanganisira mvura solubility, iyo leful gelation, firimu-inoumba kugona, uye yakanakisa rheological kutonga.
Dhigirii rekutsiva Yakakwira DS inosimudzira mvura solubility yemvura uye inoderedza tembiricha yekudziya, nepo sureme uremu hunokanganisa viscosity uye mafirimu-ekuumba maitiro. Aya midziyo inokatyamadza inoita hpmc inoenderana nehuwandu hwakawanda hwekushandisa.
2.Function yeHPMC
Kukurira uye rheology Control: HPMC zviito seyemumiriri akakura mumvura mhinduro, kuendesa visikoka uye kusimudzira kugadzikana kwekugadziriswa. Maitiro ayo epsudoplastic anobvumidza kurongeka kweiyo rheological kudzora, kugonesa kugadzirwa kwezvigadzirwa zvine zvaunoda kuyerera zvivakwa.
Film formation: Nekuda kwekugona kwayo kuumba mafirimu akajeka uye anochinjika uye hpmc inoshandiswa zvakanyanya mumatombo, mahwendefa emishonga, uye zvigadzirwa zvekutarisira pachako. Iyi mafirimu anopa zvipfukudzo zvinotsungirira, nekuchengeterwa kwakanyorova, uye kusunungurwa kwekusunungurwa kwezvinhu zvinoshanda.
Kudzokorora kwemvura: Muzvinhu zvekuvaka zvakadai semutya, mapuranga, uye zvinonamatira, HPMC inovandudza basa uye kudzivirira kurasikirwa nekukurumidza kwemvura panguva yekurapa. Izvi zvinosimudzira kuderedza, kuderedza kupaza, uye kunozivisa yunifomu yekunyora kwemasangano emisangano.
Binder uye kuparadzanisa: Mune mishonga yemishonga, Hpmc inoshanda seyekuchinjika, akabata zvisungo zvinoshanda pamwe chete mumapiritsi, makapindu, uye magirini. Uyezve, kugona kwayo kwekuzvimba uye kupaza mumvura yemidhiyamu AIDS mukuburitswa kwezvinodhaka.
Stabilizer uye Emulsifier: Hpmc inokanganisa kumiswa, emblations, uye zvipumbowo mune chikafu, cosmetic, uye maindasitiri ekushandisa. Iyo inodzivirira kupatsanurana kweheti, inochengetedza tarisiro, uye inowedzera mararamiro esherufu nekunyadzisa kukura kwecrobial uye oxidation.
3.Application yeHPMC
Pharmaceuticals: HPMC ndeyekiyi inokosha muOral Solid Dosage mafomu akadai sapiritsi, makapiniki, uye pellets. Basa rayo sechibhatiki, kuparadzaniswa, uye kudzorwa-kuburitswa-kuburitswa kunoita kuti basa rekubudirira, kuchengeteka, uye kutevedzera kwemwoyo murefu kwezvigadzirwa zvechinangwa.
Kuvaka: Mune indasitiri yekuvaka, HPMC inowedzerwa kune yeiyo coment-based zvigadzirwa zvekuvandudza kushanda, kuchengetwa kwemvura, uye kunamatira zvivakwa. Iyo inosimudzira kuita kwemauto, magiramu, ma grouts, uye anopa, anotungamira kuzvimiro zvinofadza uye anonakidza.
Chikafu uye chinwiwa: HPMC inowana application mune zvigadzirwa zvekudya seanorira, stabilizer, uye emulsifier. Izvo zvinowanzoshandiswa mumasosi, zvipfeko, zvinyararire dzimwe nzira, uye zvinhu zvekubheka zvekuvandudza zvinyorwa, muromo, uye mashelf okugadzikana.
Kuchengeta Kwemunhu: Mune cosmetics uye zvigadzirwa zvega zvega, HPMC zviito senge firimu chaimbova, thickener, uye kumhanyisa mumiririri. Izvo zviripo mumakiromita, lothns, shampoos, uye mazino, kuendesa zvinodikanwa zvekunzwa zvivakwa uye nekuwedzera zvigadzirwa zvechigadzirwa.
Pendi uye kuunganidza: HPMC inoshandiswa mumvura-yakavakirwa mapepa emvura, majasi, uye anoshambidza kugadzirisa zvevisiko, anovandudza sag kuramba, uye kuwedzera kugadzirwa kwemafirimu. Iyo inosimudzira yunifomu yekushandisa, kudenha kune substrates, uye kugadzikana kwemusoro kupedza.
4.Future maonero uye matambudziko
Pasinei nokushandisa kwayo kwakazara, zvinonetsa senge batch-kuenda kuBatch kusimba, kufunga kwekuzvidzora, uye kunetsekana kwezvakatipoteredza kunopfuurira uye kushandisirwa HPMC. Runako Research Kuedza Kuedza Kugadzirisa izvi zvinonetsa uchiongorora zvipindiriro uye zvinoshamisa synthesis nzira dzeHPMC dzerudzi.
HydroxyPropyl methylcellose (HPMC) ndeye multifonical compind ine manyorerwe ekushandisa pane mishonga yemishonga, kuvaka, chikafu, uye zvikamu zvega, uye zvikamu zveindasitiri. Yayo yakasarudzika yekusanganiswa yezvivakwa, kusanganisira kuremedza, firimu-kugadzira, kuchengetedza kwemvura, uye kusimbisa kugona, kunoita kuti zvive zvakakosha mukukura kwemazuva ano uye kwechigadzirwa. Nokunzwisisa chimiro chemakemikari, zvivakwa, uye zvinoshanda zveHPMC, maindasitiri anogona kusanganisa kugona kwayo kuti agadzire hunhu hwekugadzira uye hwakakwirira-hwekuita hunosangana nezvinodiwa zvevatengi nemisika.
