Ts'ebetso ea Kopo ea HPMC
Hydroxypropyl methyl cellulose (HPMC) ke mofuta oa non-ionic cellulose ether, e entsoeng ka thepa ea tlhaho ea polymer e le lisebelisoa tse tala 'me e hloekisoa ke letoto la mekhoa ea lik'hemik'hale. Kajeno re tla ithuta ka ts'ebetso ea ts'ebeliso ea HPMC.
● Ho qhibiliha ha metsi: e ka qhibiliha ka metsing ka tekanyo leha e le efe, khatello e phahameng ka ho fetisisa e itšetlehile ka viscosity, 'me ho qhibiliha ha ho amehe ke PH.l Organic solubility: HPMC e ka qhibiliha ka har'a li-solvents tse ling tsa tlhaho kapa li-organic solvent aqueous solutions tse kang dichloroethane, tharollo ea ethanol, joalo-joalo.
● Litšobotsi tsa gel ea mocheso: Gelisi e khutlisetsoang morao e tla hlaha ha tharollo ea bona ea metsi e futhumetse mocheso o itseng, ka ts'ebetso e laoloang ka potlako.
● Ha ho na tefiso ea ionic: HPMC ke non-ionic cellulose ether 'me e ke ke ea rarahana ka li-ion tsa tšepe kapa lintho tse phelang ho etsa precipitates tse sa qhibiliheng.
● Ho ba motenya: Mokelikeli oa eona oa metsi o ntse o teteaneng, 'me ho teteana ha oona ho amana le ponahalo ea oona, ho tsepamisa mohopolo le tsamaiso.
● Ho boloka metsi: HPMC kapa tharollo ea eona e ka monya le ho boloka metsi.
● Popeho ea filimi: HPMC e ka etsoa filimi e boreleli, e thata, le rekere, 'me e na le khanyetso e ntle ea mafura le oxidation.
● Ho hanyetsa ha enzyme: Tharollo ea HPMC e na le khanyetso e ntle ea enzyme le botsitso bo botle ba viscosity.
● botsitso ba PH: HPMC e batla e tsitsitse ho acid le alkali, 'me pH ha e amehe ka har'a 3-11. (10) Mosebetsi oa holim'a metsi: HPMC e fana ka ts'ebetso ea holim'a tharollo ho finyella emulsification e hlokahalang le liphello tse sireletsang tsa colloid.
● Thepa e khahlanong le ho senya: HPMC e eketsa thepa ea thixotropic ea tsamaiso ho putty powder, seretse, sekhomaretsi sa tile, le lihlahisoa tse ling, 'me e na le bokhoni bo babatsehang ba ho thibela ho senyeha.
● Dispersibility: HPMC e ka fokotsa tsitsipano ea sefahleho pakeng tsa mekhahlelo le ho etsa hore karolo e qhalakaneng e qhalane ka mokhoa o ts'oanang ho ba marotholi a boholo bo loketseng.
● Adhesion: E ka sebelisoa e le setlamo sa pigment density: 370-380g/l³ pampiri, hape e ka sebelisoa ho lira le likhomaretsi.
● Matla: E ka sebelisoa ho etsa rabara, asbestos, samente le lihlahisoa tsa ceramic ho fokotsa ho hohlana le ho ntlafatsa ho phunyeletsa ha seretse sa konkreite.
● Ho emisa: Ho ka thibela likaroloana tse tsitsitseng hore li se ke tsa na le ho thibela ho thehoa ha pula.
● Emulsification: Hobane e ka fokotsa tsitsipano ea sefahleho le sefahleho, e ka tsitsisa emulsion.
● Tšireletso ea colloid: Lera le sireletsang le thehoa holim'a marotholi a qhalakaneng ho thibela marotholi hore a se ke a kopana le agglomerating ho finyella phello e tsitsitseng ea tšireletso.
