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 e holimo. 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.
