Kamora ho eketsa hydroxypropyl methylcellulose ho thepa e thehiloeng ho samente, e ka ba motenya.Palo ea hydroxypropyl methylcellulose e etsa qeto ea tlhokahalo ea metsi ea thepa e thehiloeng ho samente, kahoo e tla ama tlhahiso ea seretse.
Lintlha tse 'maloa li ama viscosity ea hydroxypropyl methylcellulose:
1. Ha tekanyo ea polymerization ea cellulose ether e phahame, e kholoanyane boima ba molek'hule, 'me e phahamisa viscosity ea tharollo ea metsi;
2. Ha ho noa (kapa mahloriso) a cellulose ether, ho phahamisa viscosity ea tharollo ea eona ea metsi.Leha ho le joalo, hoa hlokahala ho ela hloko ho khetha mokhoa o nepahetseng nakong ea kopo ho qoba ho noa ho feteletseng, e leng ho tla ama mosebetsi oa seretse le konkreite.tšobotsi;
3. Joalo ka lino tse ngata, viscosity ea tharollo ea cellulose ether e tla fokotseha ka ho eketseha ha mocheso, 'me ha mocheso oa cellulose ether o phahame, ho ba le tšusumetso e kholo ea mocheso;
4. Hydroxypropyl methylcellulose tharollo hangata ke pseudoplastic, e nang le thepa ea ho kuta moriri.Ha sekhahla sa ho kuta nakong ea tlhahlobo, se fokotsa viscosity.
Ka hona, momahano oa seretse o tla fokotseha ka lebaka la matla a ka ntle, a leng molemo ho ho hahoa ha seretse, ho fella ka ho sebetsa hantle le ho kopana ha seretse ka nako e le 'ngoe.
Tharollo ea hydroxypropyl methylcellulose e tla bontša litšobotsi tsa mokelikeli oa Newtonian ha mahloriso a le tlaase haholo le viscosity e tlaase.Ha mahloriso a ntse a eketseha, tharollo e tla bontša butle-butle litšobotsi tsa mokelikeli oa pseudoplastic, 'me ha mahloriso a phahame, ho hlakile haholoanyane pseudoplasticity.
