HydroxyPropyl methylcellose (HPMC) inzvimbo yevadzidzi neiyo hydrophobic uye hydrophilic zvivakwa, ichiita kuti ive yakasarudzika mune dzakasiyana siyana maindasitiri akasiyana. Kuti tinzwisise hydrophobicity uye hydrophilicity yeHPMC, isu tinofanirwa kudzidza chimiro chavo, zvivakwa uye zvinoshandiswa zvakadzama.
Chimiro chehydroxyprupyl methylcellose:
HPMC ndeyekubva kune imwe cellulose, polymer yakasikwa inowanikwa mumadziro emusero. Kugadziridzwa kwemasero kunosanganisira kusuma kwehydroxyprupyl uye methyl mapoka mu cellulose backbone. Uku kugadziridzwa kunochinja zvivakwa zve polymer, kuendesa zvirevo zvakatsiga izvo zvinobatsira kune dzakasiyana siyana dzekushandisa.
Hydrophilicity yeHPMC:
Hydroxy:
HPMC ine hydroxypruppropyl mapoka uye ndeye hydrophilic. Aya maHydroxyl mapoka ane huwandu hwakanyanya hwekubatana kwemamolekyudhi emvura nekuda kwehydrogen kusungwa.
Hydroxyprusyl boka rinogona kuumba hydrogen zvisungo nemamolekyudhi emvura, achigadzira hpmc svutugadzike mumvura kune imwe nhanho.
methyl:
Ipo methyl boka rinopa kuHydrohobicity yeiyo molecule, haina kurwisa hydrophilikuti yeiyo hydroxpropropyl group.
Iyo methyl group inokwana isiri-polar, asi kuvapo kweiyo hydroxyprupropyl group inosarudza iyo hydrophil hunhu.
Hydrophos of HPMC:
methyl:
Mapoka emamita muHPMC sarudza kusvika kune imwe nhanho yayo yekunyepedzera.
Kunyangwe isiri yehydrophobic sevamwe vakanyatsogadzira polyners, kuvapo kwemamita methyl vanoderedza hydrophicity yeHPMC.
Firimu rinoumba zvivakwa:
HPMC inozivikanwa kune yayo yekugadzira firimu zvivakwa uye inowanzo kubatwa mumishonga yemishonga uye yekunyora. Hydrophosobicity inopa kuumbwa kwefirimu rinodzivirira.
Kubatanidzwa nezvinhu zvisina-polar:
Mune zvimwe zvekushandisa, HPMC inogona kupindirana neisiri-polar zvinhu nekuda kweiyo hydrophosity. Ichi chivakwa chakakosha kune zvinodhaka zvinodhaka system muindasitiri yemishonga yemishonga.
Zvikumbiro zveHPMC:
zvinodhaka:
HPMC inoshandiswa zvakanyanya mukuumbwa kwemishonga seyekubhuroka, firimu raimbova, uye viscosity modifier. Kugona kwayo-firimu kugadzira kunobata kudzorwa kwekusunungurwa kwezvinodhaka.
Iyo inoshandiswa mune yemuromo yakasimba dosage mafomu akadai sehata nemapiritsi.
Indasitiri yekuvaka:
Muchikamu chekuvaka, HPMC inoshandiswa muzvikamu zveComent kuti uvandudze kugona, kudzokorora kwemvura uye kuderedza.
Hydrophicicity inobatsira kuchengetedza mvura, nepo hydrophobicity inobatsira kuvandudza kudedera.
Indasitiri yechikafu:
HPMC inoshandiswa seyakakwenenzverwa uye gelling mumiririri muindasitiri yechikafu. Yayo hydrophilic yemasikirwo anobatsira kuumba maGels akagadzikana uye kudzora mavisiko ezvigadzirwa zvekudya.
cosmetic:
Mune cosmetic mafomu, HPMC inoshandiswa mune zvigadzirwa zvakadai semakiromita uye marara nekuda kweiyo firimu-inoumba uye yakakora nzvimbo.
Hydrophicicity inosimbisa yakanaka hydration yeganda.
Mukupedzisa:
HPMC iri polymer iyo iri mese hydrophilic uye hydrophobic. Chiyero pakati pehydroxyprupyl uye methyl mapoka muchimiro chayo chinopa iyo yakasarudzika inoshamisa, ichibvumira kuve neyakawandisa zvinyorwa. Kunzwisisa izvi zvivakwa kwakakosha kune tailing hpmc kusvika kune yakashandiswa maindasitiri akasiyana, uko kugona kweHPMC kuti ubatanidze nemvura uye zvinhu zvisiri izvo zvinoshandiswa zvakasiyana siyana.
