Hydroxypropyl methylcellulose (HPMC)ke polymer e qhibilihang ka metsing e sebelisoang haholo liindastering tse kang kaho, meriana, lijo le lik'hemik'hale tsa letsatsi le letsatsi. Libakeng tse chesang, HPMC e na le letoto la melemo ea bohlokoa, e etsang hore e bontše botsitso le ts'ebetso e babatsehang lits'ebetsong tse fapaneng.
1. Ho ba le botsitso bo matla ba mocheso 'me ha ho bonolo ho senya
HPMC e na le botsitso bo phahameng ba mocheso mme e ntse e ka boloka botsitso ba sebopeho sa eona sa lik'hemik'hale mochesong o phahameng. Thempereichara ea phetoho ea khalase ea eona (Tg) e phahame, hangata e ka ba 200 ° C, kahoo e ke ke ea bola kapa ea hlōleha ka lebaka la ho eketseha ha mocheso libakeng tse chesang. Sena se nolofalletsa HPMC hore e tsoele pele ho etsa mesebetsi e boima le ho boloka metsi tlas'a maemo a phahameng a mocheso, 'me e loketse liindasteri tse kang thepa ea mohaho, liphahlo le litokisetso tsa meriana.
2. Ho boloka metsi ka mokhoa o babatsehang ho thibela ho fetoha mouoane ka potlako ha metsi
Libakeng tse phahameng tsa mocheso, lebelo la ho fetoha mouoane oa metsi le potlakisa, e leng se ka etsang hore thepa e lahleheloe ke metsi habonolo le ho phatloha. Leha ho le joalo, HPMC e na le poloko e ntle ea metsi 'me e ka fokotsa tahlehelo ea metsi ka katleho. Ka mohlala, ha ho hahoa seretse le lisebelisoa tse thehiloeng ho gypsum, HPMC e ka boloka mongobo o lekaneng mocheso o phahameng, ho lumella samente kapa gypsum hore e sebetse ka botlalo nakong ea ts'ebetso ea hydration, kahoo e ntlafatsa boleng ba kaho le ho thibela ho phunyeha le ho fokotseha.
3. E tsitsitseng thickening phello le tlhokomelo ea thepa rheological thepa
HPMC ke motenya o sebetsang hantle o ntseng o ka boloka viscosity e ntle le thepa ea rheological libakeng tse chesang. Tlas'a maemo a mocheso o phahameng, li-thickeners tse ling li ka 'na tsa hlōleha kapa tsa senyeha ka lebaka la mocheso o ntseng o eketseha, ha viscosity ea HPMC e batla e sa amehe haholo ke mocheso,' me e ka boloka ts'ebetso e loketseng ea kaho libakeng tsa mocheso o phahameng le ho ntlafatsa ts'ebetso ea thepa. Ka mohlala, indastering ea ho roala, HPMC e ka thibela liphahlo hore li se ke tsa theoha ka mocheso o phahameng le ho ntlafatsa ho tšoana le ho khomarela liphahlo.
4. Letsoai le letle le ho hanyetsa alkali, ho ikamahanya le maemo a rarahaneng
Tlas'a maemo a phahameng a mocheso, lik'hemik'hale tse ling li ka fetoha 'me tsa ama thepa ea thepa. HPMC e na le mamello e ntle ho li-electrolyte (tse kang matsoai le lintho tsa alkaline) 'me e ka boloka mesebetsi ea eona mocheso o phahameng le libaka tse phahameng tsa alkaline. Sena ke sa bohlokoa ka ho khetheha seretseng sa mohaho, lihlahisoa tsa gypsum le liindasteri tsa ceramic, hobane lisebelisoa tsena hangata li hloka ho sebelisoa ka mocheso o phahameng le ho pepesehela libaka tsa alkaline.
5. Thermal gelation properties, e ka sebelisoa bakeng sa likopo tse khethehileng tsa mocheso o phahameng
HPMC e na le thepa e ikhethang ea gelation ea mocheso, ke hore, tharollo ea eona ea metsi e tla phalla ka har'a mocheso o itseng. Thepa ena e ka sebelisoa lits'ebetsong tse ling tsa mocheso o phahameng. Mohlala, indastering ea lijo, HPMC e ka sebelisoa ho hlahisa li-noodle hang-hang. Ha mocheso o ntse o phahama, o ka etsa gel e tsitsitseng, ho ntlafatsa tatso le morphological botsitso ba lijo. Lefapheng la meriana, thepa ea gelation ea mocheso ea HPMC e ka boela ea sebelisoa ha ho lokisoa lithethefatsi tse laoloang ho netefatsa botsitso ba tekanyo ea ho lokolloa ha lithethefatsi tlas'a maemo a fapaneng a mocheso.
6. Eco-friendly, e seng chefo le e se nang kotsi
HPMC ke lintho tse sireletsehileng le tse se nang chefo tsa polymer tse ke keng tsa lokolla lintho tse kotsi kapa tsa hlahisa monko tlas'a maemo a phahameng a mocheso. Ha ho bapisoa le li-thickeners tse ling kapa li-additives tse ka 'nang tsa lokolla li-volatile organic compounds (VOCs) ka mocheso o phahameng, HPMC e na le botsoalle ba tikoloho le ho finyella litlhoko tsa tsoelo-pele e tsitsitseng ea morao-rao. Ka hona, HPMC ke khetho e nepahetseng masimong a joalo ka kaho ea mocheso o phahameng kapa phepelo ea lijo.
7. E sebetsa ho mefuta e fapaneng ea likopo tsa tikoloho ea mocheso o phahameng
Melemo ena ea HPMC e etsa hore e sebetse haholo libakeng tse fapaneng tsa mocheso o phahameng. Ka mohlala:
Indasteri ea kaho: e sebelisoang seretseng sa samente, sekhomaretsi sa lithaele, le lihlahisoa tsa gypsum ho ntlafatsa ho boloka metsi le ts'ebetso ea kaho le ho thibela ho tsoa mouoane ho feteletseng ha metsi ho bakoang ke mocheso o phahameng.
Indasteri ea ho roala: e sebelisoa ka lipente tse thehiloeng metsing le lipente tsa latex ho boloka botsitso ba rheological le ho thibela ho theoha maemong a mocheso o phahameng.
Indasteri ea lijo: e sebelisoang lihlahisoa tse halikiloeng le lihlahisoa tsa lijo tse potlakileng ho ntlafatsa botsitso ba lijo nakong ea ts'ebetso e phahameng ea mocheso.
Indasteri ea meriana: e sebelisoang matlapeng a sa khaotseng le litokisetso tsa li-gel ho netefatsa botsitso le bioavailability ea lithethefatsi tlas'a maemo a phahameng a mocheso.
HPMCe na le botsitso bo babatsehang ba mocheso, ho boloka metsi, ho teteaneng, ho hanyetsa alkali le thepa ea tšireletso ea tikoloho libakeng tse chesang, 'me e ka sebelisoa haholo libakeng tse ngata tse kang kaho, liaparo, lijo le meriana. Ts'ebetso ea eona e tsitsitseng tlas'a maemo a phahameng a mocheso o nolofalletsa lihlahisoa tse amanang le tsona ho boloka mesebetsi e babatsehang libakeng tse feteletseng, ka tsela eo ho ntlafatsa boleng ba tlhahiso le kaho, ho fokotsa tahlehelo ea thepa, le ho netefatsa ho tšepahala ha sehlahisoa sa ho qetela.
