HydroxyPropyl methylcellose (HPMC) ndeye cellulose inobviswa zvakanyanya kushandiswa mumasango akasiyana-siyana senge mishonga, chikafu uye kuvaka. Inoshanda kwayo uye zvivakwa zvinoita kuti ive yakakosha, kunyanya muindasitiri yemishonga iyo inoshandiswa seyekuchinjika, kumisa mumiriri uye viscosity-kuwedzera mumiririri. HPMC inozivikanwawo zvakanyanya kune zvivakwa zvemvura yayo yekuchengetwa, izvo zvinoita basa rakakosha mune dzakasiyana siyana zvigadzirwa uye zvinoshandiswa.
Kuchengeta kwemvura kugona kwechinhu chekubata kana kuchengetedza mvura. Panyaya yeHPMC, ndiko kugona kutora uye kuchengetedza mvura, kunyanya mumvura mhinduro. Kuchengetwa kwemvura kweHPMC kunokanganiswa nezvinhu zvakati wandei, kusanganisira yaro yekusangana, viscosity, tembiricha nePH.
Chimwe chezvinhu zvikuru zvine chekuita nekuchengetwa kwemvura kweHPMC ndeyekumanikidza kwayo. HPMC ine yakakwira mvura yekuchengetera nzvimbo yakakwirira kwazvo. Sezvo kusangana kweHPMC kunowedzera, visikopa yaro inowedzera, inokonzerwa nekukwira kwemvura yakakwirira yekuchengetedza. Nekudaro, zvakanyanyisa kukwira kwekusungirwa kunogona kukonzera kuderera kwemvura kuchengetedza kwemvura, saka kukanganisa maitiro ese echigadzirwa.
Chimwe chinhu chinokanganisa kuchengetwa kwemvura kweHPMC ndeye viscosity. Viscosity inoreva kuyerera kuramba kweHPMC. Iyo yepamusoro iyo viscosity, yakakwira kuchengetedza kwemvura. Nekudaro, viscosity yakakwira inogona zvakare kukonzera kuparadzaniswa kwakashata, izvo zvinogona kukanganisa chigadzirwa chiitiko. Naizvozvo, chiyero chakakodzera pakati pevisikoka uye kugona kwemvura kunofanirwa kuchengetedzwa kuti uwane mhedzisiro yaunoda.
Tembiricha inokanganisawo mvura yekuchengeta kwemvura yeHPMC. Kumhepo yepamusoro, HPMC ine yakadzika mvura yekuchengetwa. Izvi zvinodaro nekuti kupisa kwakanyanya kunogona kukonzera kushomeka, kukonzera HPMC kurasikirwa kugona kwayo kuchengetedza mvura. Mukupesana, kupisa kwakadzika kunosimudzira kudzokorora kwemvura, kugadzira HPMC yakanakira zvigadzirwa izvo zvinoda kuchengetwa kwemvura, zvakadai sekiriniki uye marara.
Iyo PH Kukosha kweSolution inobatawo kuchengetwa kwemvura kweHPMC. Pakadzika pH mazinga, HPMC ine yakakwira mvura yekuchengetwa. Izvi zvinodaro nekuti mamiriro epidic anokurudzira kusimudzira kwemvura muHPMC. Kune rimwe divi, HPMC ine yakaderera mvura yekuchengetwa kwemvura muhotsi yakakwira ph. Alkaline mamiriro anogona kukonzera HPMC kurasikirwa nemvura yekuchengetwa kwemvura, zvichikonzera kuita zvisina kunaka.
Kuchengetwa kwemvura kweHPMC chinhu chakakosha icho chinokanganisa mashandiro azvo uye kushanda mune zvakasiyana siyana zvigadzirwa uye zvinoshandiswa. Iyo inokanganiswa nezvinhu zvakawanda, kusanganisira kusimbisa, viscosity, tembiricha nePH. Kuti uwane mhedzisiro yaunoda, chiyero chakakodzera chinofanira kuchengetwa pakati pezvinhu izvi. HPMC's yakanakisa mvura yekuchengetwa inoita kuti ive yakakodzera incrient mune dzakasiyana siyana zvigadzirwa, kusanganisira mishonga yemishonga, zvekudya nezvikafu nezvivakwa zvekuvaka. Sezvatinoenderera mberi nekuongorora zvarwo zvinhu uye kugona, HPMC inotarisirwa kutamba yakakosha muindasitiri akasiyana-siyana, kupa mukuvandudzwa kwezvinhu zvakapfuura uye zvakavandudzwa.
