1) Ponahalo:HPMCke nonionic cellulose ether, phofo e tšoeu e bosoeu bo bosoeu kapa granule, ha e na monko ebile ha e na tatso, e qhibilihisoa metsing a batang, glacial acetic acid, ethanol, methanol le propylene glycol, e qhibilihang hanyane ka har'a acetone ho latela tekanyo ea lintho tse ling, hoo e batlang e sa qhibilihe metsing a chesang. , ethylene glycol le toluene.HPMC e qhibiliha ka motsoako oa 10% methanol le 90% methylene chloride ho etsa litharollo tsa colloidal.
2) Tharollo ea HPMC e na le ts'ebetso e holimo, pepeneneng e phahameng, le ts'ebetso e tsitsitseng.Ha mocheso o le mocheso o itseng, tharollo e fetoha maru kapa e etsa gel ea flocculent.Leha ho le joalo, tharollo e hlaka hape ka mor'a ho pholile.Mefuta e fapaneng ea HPMC e na le mocheso o fapaneng oa gelation.The solubility e fapana ho ea ka viscosity.Ha viscosity e tlase, e na le solubility e phahameng.Mefuta e fapaneng ea HPMC e fapane ho tse ling 'me ho qhibiliha ha tsona metsing ha ho amehe ke pH.
3) Boholo ba likaroloana: sekhahla sa ho feta sa 100% ho 80 mesh.
4) Boima bo bonahalang: 0.25-0.70 g/mL (hangata hoo e ka bang 0.5 g/mL), boima bo khethehileng 1.26-1.31mL.
5) Mocheso oa ho fetola mebala: 190-200 ° C;Mocheso oa carbonization: 280-300°C.
6) Khatello ea sefahleho: 42-56 dyn / cm (2% tharollo ea metsi).
7) Lintho tse phahameng tsa methoxy ho HPMC, mocheso o tlase oa gelation, le ho qhibiliha ho hoholo ha metsi le holim'a metsi.
8) HPMC e na le litšoaneleho tse ling, mohlala, thepa e teteaneng, botsitso ba pH, ho boloka metsi, thepa e ntle ea ho etsa filimi, ho qhalakanngoa hantle le bokhoni ba ho khomarela.
