Hydroxyprupyl methylcellose (HPMC)Inosemesa mheremalose inoshandiswa zvakanyanya kushandiswa muindasiti dzakasiyana-siyana, kusanganisira mishonga yemishonga, chikafu, uye kuvaka, nekuda kwechimiro chayo chakasarudzika. Imwe yeiyo yakaoma nzvimbo yekusagadzikana®HPMC iyo inosimudzira kushandisirwa kwayo kwemvura yayo inotonhora. Iyi ficha inoita basa rakakosha mukuona kushanda kwayo mumanyorero akasiyana-siyana, kubva kubva kuMishonga mafomu ekusimbisa uye kuomerera.
Kuongorora kweHPMC
HPMC is nonitic cellulose ether inotorwa kubva kune yakasikwa cellulose nekuburitsa hydroxypruppropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropyl uye methyl mapoka. Uku kugadziridzwa kunoguma polymer iyo inonyungudika mumvura uye inoratidza maitiro eTermogelling. Kana ikanyungudika, Hpmc inoumba viscous, inopa mhinduro, inopa kuremedza, firimu-kugadzira, uye kusimbisa zvivakwa.
Imwe yehunhu hwakakosha hweHPMC ndiko kugona kwayo kuparadzira mumvura inotonhora pasina kugadzira mapundu kana ekuunganidza. Ichi chivakwa chinorerutsa kubata kwayo uye application, ichiita kuti ive yakanakira muindasitiri inoda chaizvo uye inoshanda inosanganiswa.
Michina yemvura inotonhora yemvura
Iyo inotonhora mvura inopararira yeHPMC inonyanya kutongwa nenzvimbo dzayo pamusoro uye hydration kinetics. Makiyi makiyi anosanganisira:
Sosi yekugadziridzwa: HPMC zvikamu zvinowanzoitirwa nevamiriri vepamusoro-shanje kana hydrophilic yematanho ekuwedzera kupararira kwavo. Uku kurapwa kunoderedza kududzira kubatana, kubvumira zvidimbu kuti zviparadzanise nyore nyore mumvura.
Hydration Kinetics: Kana ikaunzwa mumvura inotonhora, mapoka ehydrophilic muHPMC anokwezva mamorekuru emvura. Yakadzorwa hydration inovimbisa kupararira zvishoma nezvishoma, kudzivirira kuumbwa kwemasumbu kana gel masasi.
Tembiricha Inonzwa: HPMC inoratidza yakasarudzika yekubatanidza chimiro. Inopaza zviri nyore mumvura inotonhora asi inoumba gel sekuwedzera kwe tembiricha. Iyi tembiricha-inotsamira maitiro AIDS mune iyo kunyange kugovera zvimedu panguva yekutanga kupararira.
Zvinhu zvinopesvedzera kutonhora kwemvura kupararira
Zvinhu zvinoverengeka zvinopesvedzera mvura inotonhora yekupararira kweHPMC, kusanganisira yayo molecular chimiro, saizi yehukuru, uye mamiriro ezvinhu epakatiripiti:
Molecular uremu: iyo smecular uremu hwekusagadzikana®hpmc inosarudza mavekisipa ayo uye hydration chiyero. Lower elecular uremu mamakisi anodzikisira nekukurumidza mumvura inotonhora, nepo yakakwira mamelecular uremu mamakisi angangoda kuwedzera kwekuwedzera.
Subgray degree: iyo degree re hydroxyprupyl uye methyl kutsiva inokanganisa hydrophilicity yeHPMC. Yakakwirira kutsiva mazinga anovandudza kushamwaridzana kwemvura, kusimudzira kupararira.
Saizi yeChipenga: Yakapfigira HPMC Pody Pody Durperse zvakanyanya nekuda kwenzvimbo yavo yekuwedzera. Nekudaro, zvakanyanyisa zvidimbu zvakanaka zvinogona kuwedzera, kuderedza kupararira.
Unhu hwemvura: Kuvapo kweINS uye kusachena mumvura kunogona kukanganisa hydration uye kupararira maitiro eHPMC. Mvura yakapfava, yakadzikira mvura inowanzowedzera kuparadzaniswa.
Kusanganisa mamiriro: Maitiro akakodzera ekusanganisa, akadai anononoka uye nekuwedzera kweHPMC kusvika kumvura nekuenderera mberi kwekunaka, simbisa kuparadzaniswa kwakakwana uye kuderedza kuderedza.
Zvikumbiro zvinobatsirwa kubva mukuparadzwa kwemvura kunotonhora
Kugona kweHPMC kuti kuparadzanise mumvura inotonhora kune zvakakoshesa zvikumbiro zvawo:
Mishonga yechechi: Mukugadzira zvinodhaka, kutonhora kwemvura kunopararira yunifomu kusanganisa uye kusawirirana mumitsetse, magirel, uye majasi. Ichi chivakwa chinonyanya kutsoropodza mumapiritsi ekudzora-masheya, uko kupararira chaiko kunobata zvinokanganisa zvinodhaka zvinodhaka.
Indasitiri yechikafu: Kupararira kwaHPMC kunofambisa kushandiswa kwayo seanoti, STabilizer, uye emulsifier mune zvigadzirwa zvakadai soups, sosi, uye madhayeti. Inotendera kubatanidzwa kuri nyore pasina kuumbwa kwechigunwe, kunoita kuti maumbirwo akajeka.
Zvivakwa zvekuvaka: Mune masangano-akavhenekerwa masisitimu, akadai semagetsi anoshongedza, mvura inotonhora, inopararira HPMC inosanganisira kusanganisa kusanganisa kwehomogenes, kuvandudza basa, kudengenyeka, uye kuchengetwa kwemvura.
Zvigadzirwa zvega zvega: HPMC inoshandiswa muShampoos, lotions, uye kirimu nekuda kwekupararira kwayo uye mafirimu-ekugadzira mafirimu ekugadzira. Iyo inovimbisa kugoverwa yunifomu yezvisungo zvinoshanda uye zvinosimbisa kugadzikana kwechigadzirwa.
Kuvandudza Kuparadzaniswa Kwemvura
Kuti uvandudze mvura inotonhora yekupararira HPMC, vagadziri vanoshandisa nzira dzakasiyana-siyana:
Kurapa kwepasi: Coating HPMC zvidimbu nekuparadzira vamiririri kana kugadzirisa zvivakwa zvavo zvepamhepo zvinoregedza zvinokanganisa uye zvinowedzera kudyidzana kwemvura.
Granulation: Shanduko HPMC Pody muGranules inoderedza guruva uye inosimudzira kuyerera uye kuparadzaniswa.
Optimised Kugadziriswa: Kunyatsotonga kwekunyima, kuomesa, uye matanho ekuisa anovimbisa kusingawirirane kusingaperi saizi uye zvinyoro-nyoro, izvo zviviri zvinokanganisa.
Kushandiswa kweBlends: Kubatanidza HPMC nedzimwe poluble polymers kana yekuwedzera inogona kuenzanisa kuparadzaniswa kwayo kune zvakanyatso.
Zvinonetsa uye zvisingakwanisi
Kunyangwe zvakanakira, iyo inotonhora mvura yekupararira yekusagadzikana®HPMC inounza mamwe matambudziko. Yakakwira-vcosity mamakisi ingangoda kwenguva refu inosangana nguva kana zvishandiso zvine hunyanzvi kuti uwane kupararira kwakazara. Uyezve, zvinhu zvematendekwari zvakadai sekuomesa kwemvura uye kupisa kusiyana kunogona kukanganisa maitiro ayo.
Imwe mhedzisiro ndiyo mukana wechizvarwa chechizvarwa pakubata, chinogona kuisa hutano hwepamoyo uye zvakatipoteredza. Maitiro akakodzera ekubata uye kushandiswa kwemafomu akarwa kunogona kudzikisira nyaya idzi.
Mvura inotonhora yekupararira kwehydroxypruppropyl methylcelloseIcho chivakwa chinokatyamadza chinoratidzira kupesana kwayo uye kushandisirwa maindasitiri. Nekunzwisisa maitiro uye zvinhu zvinopesvedzera kupararira, vagadziri vanogona kurongedza HPMC mafomu ekusangana nezvakangoita application. Kufambira mberi mukugadziridzwa kwemusoro, maitiro egranguulation, uye kuumbwa kusiyanisa ichiramba ichisimudzira maitiro uye kushandisirwa kweichi chinoshamisa cellulose chinobva. Sezvo kudikanwa kwekushanda, kusimba, uye zvinhu zvakakwirira-kuita zvinokura, basa reHPMC sechinhu chomuzvivakwa chemuzhinji chichagara chingaruramira.
