HyproMellose, anozivikanwa zvakare se hydroxyprupyl methylcellose (HPMC), inzvimbo yeiyo synther yakatorwa kubva ku cellulose. Iyo inoshandiswa zvakanyanya mune yemishonga, chikafu uye maindasitiri ezvidhinari seanoshamwaridzana, emulsifier uye binder. HPMC chinhu chisiri chepfu uye biodegracable chinhu, ichiita kuti ive yakachengeteka uye yakasimbisa shamwari sarudzo.
1. SoluBility yemvura
HPMC inonyungudika mumvura uye inoumba yakajeka kana zvishoma opalescent mhinduro. Iyo solubility yeHPMC zvinoenderana neye viscosity giredhi, suremu uye dhigiri rekutsiva. Yakakwira viscosity uye molecular uremu mamakisi isinganyanye kushoma pane kuderera mamakisi. Dhigirii rekutsiva racho rinosarudza huwandu hwe hydroxypruppropyl uye methyl mapoka akasungirirwa kune HPMC Cellulose Backbone. Iyo yakakwira iyo degree rekutsiva, iyo yakaderera mvura yekurudyi.
2. Kemical Kugadzirisa
HPMC inogadziriswa nemakemikari uye haiite nemakemikari mazhinji uye elorganic. Iyo inopesana neAlkalis, isina kusimba acids uye yakawanda organic sol sol. Nekudaro, HPMC inobata neakasimba acids uye oxidizing vamiririri, zvichitungamira kusvibiswa kwayo uye kurasikirwa kwekuita. Naizvozvo, zvinokurudzirwa kudzivisa kufumura HPMC kune yakasimba acids kana oxidizing vamiririri.
3. Firimu-kugadzira zvivakwa
HPMC ine yakanaka firimu-inoumba zvivakwa uye yakakodzera kune piritsi yekuvhara, yakasimba kuburitswa ichivharira uye yekuvhara. Iyo firimu yakaumbwa neHPMC inoshanduka-shanduka, pachena uye yakatsetseka. Iyo firimu inodzivirirawo kusvibiswa kweiyo inoshanda inoshanda mu piritsi kana kaputera.
4. Thermal Glation
Zvichienderana negiredhi rayo viscosity, HPMC iri pasi pegreen thermal denderedzwa kana ichipiswa mumvura pamusoro pemamwe tembiricha. Tembiricha yegwenzi inoshatisa kubva pa50 ° C kusvika 90 ° C. Iyo Gel inoumbwa neHPMC inoshanduka, zvichireva kuti inogona kunyungudika kumashure kune mvura yemvura nekutonhora. Ichi chivakwa chinoita hpmc yakakodzera kushandiswa mune inodzorwa-kuburitswa mafomu, sezvo mushonga wacho unogona kusunungurwa pakudziya chaiko.
5. Rheological Properties
HPMC inoratidza pseudoplastic maitiro, zvichireva kuti viscoity yayo inoderera nekuwedzera shear rate. Ichi chivakwa chinoita kuti HPMC yakakodzera kushandiswa seanotenderedza uye stabilizer mune chikafu uye cosmetic mafomu. HPMC inoshandiswawo seyekumirisa mumiriri nekuda kweiyo thisxotropic maitiro, zvinoreva kuti viscoity yayo inoderera pasi pekuenderera mberi kwesimba rekuenderera mberi.
HPMC chinhu chose chose uye chakachengeteka chinhu nemakemikari akanaka emakemikari. Yayo Solubility Solubility, makemikari kugadzikana, firimu-kugadzira zvivakwa, Thermogelling uye zvivakwa zvimisheni zvinoita sarudzo yakakurumbira mumaindasitiri akasiyana siyana. HPMC iri zvakare biodegradable uye zvakatipoteredza hushamwari, zvichiita sarudzo yakasimba.
