hydroxyethyl methyl cellulose (HEMC) ke eng?
Hydroxyethyl methylcellulose(HEMCe boetse e tsejoa e le methylhydroxyethyl cellulose (MHEC).Ke karoloana e tšoeu, e bosoeu, kapa bosehla bo bosoeu.Ke non ionic cellulose ether e fumanoang ka ho eketsa ethylene oxide ho methyl cellulose.E entsoe ka li-polymers tsa tlhaho tse nchafalitsoeng tse kang makhasi a lehong kapa k'hothone, 'me HEMC e ka sebelisoa e le moemeli ea phahameng oa ho boloka metsi, sekhomaretsi le filimi ea ho etsa filimi, stabilizer, joalo-joalo E sebelisoa haholo lits'ebetsong tse sa tšoaneng tsa indasteri, tse kang oli. ho cheka, ho haha le ho haha, pente le liphahlo, meriana, joalo-joalo.HEMCe ka fetoloa ho latela litlhoko tsa bareki, 'me ka mor'a ho fetoloa, e ntse e na le khanyetso e ntle ea ho sagging le ho sebetsa hantle.Batla ho sebelisaHEMCmolemong oa indasteri?Ka kopo ikopanye le mofani oa thepa ea tšepahalang oahydroxyethyl methyl celluloseho fumana khoebo e ntle.
HEMCe na le mesebetsi e fapaneng.Li kenyelletsa:
1. Ponahalo
HEMCe ka ba bosweu, bosehla bo kganyang, bosweu bo mosehla, kapa bosweu bo putswa.
2. Sollubility
HEMCe qhibiliha ka metsing (a batang kapa a chesa).Leha ho le joaloHEMCHa e qhibilihe ka har'a metsoako e mengata ea lintho tse phelang, e qhibiliha ka har'a metsoako ea metsoako ea 'mele ea tlhaho ea tlhaho le ea tlhaho.
Boima ba eona bo phahameng bo itšetlehile ka viscosity, 'me ho qhibiliha ha eona ho fapana le viscosity.The viscosity e ka tlaase, e kholoanyane ea ho qhibiliha, 'me ka tsela e fapaneng.
3. Ho tsitsa ha pH
HEMCe tsitsitse ka har'a 3.0-11.0 'me viscosity ea eona e batla e sa amehe, empa ho feta moeli ona ho tla fokotsa viscosity ea eona.
4. Metabolism
HEMCke ntho e sa sebetseng e sebelisoang haholo lijong le meriana ka lebaka la ho se khone ho etsa metabolism.
5. Mosebetsi oa holim'a metsi
Ka lebaka la ts'ebetso ea eona e sebetsang ka holim'a litharollo tse nang le metsi, e ka sebelisoa e le dispersant, protector, and emulsifier.
6. Ho hanyetsa li-fungus
Ka polokelo ea nako e telele,HEMCe na le botsitso bo botle ba viscosity, ka hona e na le khanyetso e ntle ea hlobo.
Matla a eona a anti hlobo a phahame ho feta a hydroxyethyl cellulose.
7. Ho boloka metsi
HEMCe fetoha moemeli ea sebetsang hantle oa ho boloka metsi ka lebaka la viscosity ea eona e phahameng ka tharollo ea metsi.
Matla a eona a ho boloka metsi a maholo ho feta a methyl cellulose.
8. Likahare tsa molora

9. Thermal conductive sekhomaretsi
Ha theHEMCtharollo e futhumetse mocheso o itseng, ponahalo ea eona e fokotseha, e etsa sediment le gel, empa haeba e pholile, e tla khutlela boemong ba pele ba tharollo.
