Tlhaloso ea Sehlahisoa:
Hydroxypropyl Methylcellulose (HPMC) ke phofo e tšoeu e sa nkheng, e seng chefo.Ka mor'a hore e qhibilihe ka ho feletseng ka metsing, e tla etsa tharollo e hlakileng ea viscous.Ke ether e seng ea ionic cellulose e entsoeng ka thepa ea tlhaho ea polymer ka letoto la ts'ebetso ea lik'hemik'hale.E na le litšoaneleho tsa ho teteana, ho khomarela, ho qhalakanngoa, emulsification, sebopeho sa filimi, ho emisoa, adsorption, gelation, mosebetsi oa holim'a metsi, ho boloka mongobo le ho sireletsa li-colloids.
Kopo:
Ho qhibiliha ha metsi le bokhoni ba ho teteka: e ka qhibiliha ka metsing a batang, 'me ea etsa tharollo e hlakileng ea viscous.
Ho qhibiliha ka har'a metsoako ea lintho tse phelang: Kaha e na le palo e itseng ea lihlopha tsa hydrophobic methoxy, sehlahisoa sena se ka qhibiliha ka har'a metsoako e meng ea tlhaho.
Ho tsitsa ha boleng ba PH: The viscosity ea HPMC's aqueous solution e batla e tsitsitse ho mefuta ea PH ea boleng 3.0-11.0.
Ts'ebetso ea bokaholimo: Tharollo ea metsi ea HPMC e na le ts'ebetso ea bokaholimo.E na le phello ea emulsifying, e sireletsang bokhoni ba colloid le botsitso bo lekanyelitsoeng.
Thermal gelation: Ha e futhumatsoa ka holim'a mocheso o itseng, tharollo ea metsi ea HPMC e ka fetoha opaque, ea hlahisa pula, 'me ea lahleheloa ke viscosity.Leha ho le joalo, butle-butle e ile ea fetoha boemo ba pele ba tharollo ka mor'a ho pholile.
Likahare tse tlaase tsa molora: HPMC ha e na ionic, e ka hlatsuoa ka metsi a chesang nakong ea ho lokisetsa le ho hloekisoa ka katleho, kahoo molora oa eona o tlaase haholo.
Ho hanyetsa letsoai: Kaha sehlahisoa sena ke electrolyte e seng ea ionic le e seng polymeric, e batla e tsitsitse ka tharollo e nang le metsi a letsoai la tšepe kapa li-electrolyte tsa organic.
Tšusumetso ea ho boloka metsi: Hobane HPMC ke hydrophilic mme tharollo ea eona ea metsi e na le viscous haholo.E ka kenyelletsoa ho seretse, gypsum, pente, joalo-joalo ho boloka ho boloka metsi a mangata sehlahisoa.
Ho hanyetsa hlobo: E na le khanyetso e ntle ea hlobo, 'me e na le botsitso bo botle ba viscosity nakong ea polokelo ea nako e telele.
Lubricity: Ho eketsa HPMC ho ka fokotsa coefficient ea likhohlano le ho ntlafatsa mafura a lihlahisoa tsa ceramic tse extruded le lihlahisoa tsa samente.
Thepa ea ho etsa lifilimi: E ka hlahisa li-flakes tse matla, tse tenyetsehang, tse bonaletsang tse nang le oli e ntle le ester resistance.
Linthong tsa kaho, selulose ea HPMC e ka sebelisoa e le ntho e bolokang metsi le ho khutlisetsa morao bakeng sa seretse sa samente ho etsa hore seretse se pompehe.
Joaloka sekhomaretsi, tšebeliso ea HPMC ka li-plaster, gypsum, putty powder kapa lisebelisoa tse ling tsa mohaho li ka ntlafatsa ho ata ha tsona le ho lelefatsa nako ea tsona ea ho sebetsa.
Ho boloka metsi a eona ho ka thibela pente hore e se ke ea phunyeha ka potlako ka mor'a ho roala, hape e ka matlafatsa matla a ho roala ka mor'a ho thatafala.
Ntle le moo, lik'hemik'hale tsa HPMC le tsona li ka sebelisoa e le sehlahisoa sa ho khomarela lithaele, 'mabole le mokhabiso oa polasetiki indastering ea kaho.
Ntle le moo, phofo ea HPMC e sebelisoa e le motenya, stabilizer, emulsifier, excipient, le moemeli oa ho boloka metsi ha ho etsoa indasteri e meng, joalo ka lik'hemik'hale tsa petrole, liaparo, thepa ea ho haha, ho tlosa pente, lik'hemik'hale tsa temo, enke, khatiso ea masela le ho daea. li-ceramics, ho etsa pampiri, litlolo, joalo-joalo.
Sephutheloana: 25 kgs / mokotla kapa kamoo u batlang.
Polokelo: Boloka sebakeng se nang le moea o pholileng, se omileng.
Maemo a phethiloeng: Maemo a Machabeng.
