1. Mocheso oa gel (tharollo ea 0.2%) 50-90 ° C.
2. E qhibiliha ka metsing le ka bongata ba polar c le karolo e loketseng ea ethanol / metsi, propanol / metsi, dichloroethane, joalo-joalo, e sa qhibilihe ka har'a ether, acetone, absolute ethanol, 'me e ruruha ka ho hlaka kapa ho senyeha hanyenyane metsing a batang a colloidal solution. Tharollo ea metsi e na le mosebetsi oa holim'a metsi, pepeneneng e phahameng le ts'ebetso e tsitsitseng.
3. HPMC e na le thepa ea gelation ea mocheso. Sehlahisoa se nang le metsi a metsi se futhumetse ho etsa gel le precipitates, ebe e qhibiliha ka mor'a ho pholile. Mocheso oa gelation oa litlhaloso tse fapaneng o fapane. Sollubility e fapana ho ea ka viscosity. The viscosity e ka tlaase, e kholoanyane ea ho qhibiliha. Litlhaloso tse fapaneng tsa HPMC li na le phapang e itseng linthong tsa tsona, 'me ho qhibiliha ha HPMC metsing ha ho amehe ke boleng ba pH.
4. Boholo ba likaroloana: 100 mesh pass rate e kholo ho feta 98.5%. Boima ba bongata: 0.25-0.70g/ (hangata ho pota 0.4g/), matla a khoheli a itseng 1.26-1.31. Mocheso oa ho fetoha ha mebala: 180-200°C, mocheso oa carbonization: 280-300°C. Boleng ba methoxyl bo tloha ho 19.0% ho isa ho 30.0%, mme boleng ba hydroxypropyl bo tloha ho 4% ho isa ho 12%. Viscosity (22°C, 2%) 5～200000mPa .s. Mocheso oa gel (0.2%) 50-90°C
5. HPMC e na le litšoaneleho tsa bokhoni bo matla, ho tsoa letsoai, botsitso ba PH, ho boloka metsi, botsitso ba dimensional, thepa e babatsehang ea ho etsa filimi, mefuta e mengata ea ho hanyetsa li-enzyme, ho arohana le ho kopana.
