HydroxypropypropyLese (HPMC)Na hangata e sebelisoa khafetsa ka likokoanyana tse fapaneng tsa lits'ebetso, haholo masimong a meriana, litlolo, lijo le thepa ea ho aha. Ha se ea lebellang, empa polymer ea qhibilihang ea metsi e ka qhibilihang metsing mme o theha tharollo ea colloridal e kholo. Khoebo ea le lintho tse tšoenyehe®mmbc ho latela palo le boemo ba methyl le boemo ba hydroxypropyl ka sebopeho sa eona sa maiketsetso.
1. Thepa ea mantlha ea hydroxypropyl methylcell
HydroxyproPypropinyL methylcelulose e fumanoa ke methyllase le hydroxypropylase ea cellulose. Ceploulose ka boeona ke polysaccharide ea tlhaho ea tlhaho e teng marakong a lik'hasaleng tsa semela. Sebopeho sa lik'hemik'hale sa HPM se entsoe haholo likarolo tsa Glucose, tseo lileng tsa litulo li hokahaneng ke maqhama a β-1,4 GlyCsidic. Ka sebopeho sena sa linomoro, lihlopha tse ling tsa hydroyl li nkeloa sebaka ke methyl (-Ch₃) le hydroxypropyl (-c₃h₇oh),-li-silebility tse ling le lik'hemik'hale le tsa lik'hemik'hale le tsa lik'hemik'hale le tsa lik'hemik'hale.
Fulubility ea HPMC e anngoe ke sebopeho sa limolek'hule mme hangata e na le litšobotsi tse latelang:
Sello sa metsi: HPMC e ka theha tharollo ea li-viscous ka metsing mme e qhibiliha kapele. SELUBILIT ea eona e amana haufi le mocheso oa metsi le boima ba limok'hule tsa HPMC.
Litaba tse phahameng: Ka ho tsepamisa mohopolo ho itseng, tharollo ea HPMC e bontša pono e phahameng, haholo-holo linthong tse phahameng tsa moleng oa molemi.
HPM ea futhumatsang: HPMC e na le botsitso bo botle ka mefuta e itseng ea lithempa 'me ha ho bonolo ho bola ka menoana e itseng.
2. Fulbility of Hpmc
HPMC ke ntho e qhibilihang ea metsi, empa ha e nyenyefatsoe ke li-solvents tsohle. Boitšoaro ba eona ba ho qhala bo amana le polao ea phelisang le tšebelisano lipakeng tsa limolek'hule tsa solvent le limolek'hule tsa HPMC.
Metsi: Hpmc e ka qhibiliha ka metsing. Metsi a bona a tloaelehileng haholo, 'me nakong ea khefuloho, lentohelo ea khefu ea pherekano e tla etsa litlolo tsa metsi le limolek'hule tsa metsi ho fihlela pherekano ea metsi. Tenyo ea timetso e angoa ke lintho tse kang boima ba limomko, tekanyo ea methylation le hydropyproppylation, mocheso, le boleng ba metsi. Hangata, sello sa hpmc ke sona se molemohali Ph Tikoloho ea ho se nke lehlakore.
Li-solvent tsa manyolo: HPMC e batla e sa khathatse libekeng tse ngata tsa manyolo, tse kang lino-holo, le hydrocarbork. Lebaka ke hobane sebopeho sa eona sa lisele se na le lihlopha tsa hydrophilic hydroxyl le lithyl tsa methyl le lihlopha tsa hydroxypropyl. Le ha e na le moea o matla bakeng sa metsi, e na le phetisetso e fosahetseng le li-solvents tse ngata tsa manyolo.
SELUBUBING ea metsi a chesang: ka metsing a futhumetseng (hangata ho 40 ° C ho fihlela 70 ° C ho ea ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho isa ho 70 ° C ho 32 Ha mocheso o ntse o eketseha, sekhahla sa disfonot le linyeoe li tla eketseha, empa ka mocheso o phahameng haholo, pono ea tharollo e kanna ea ameha.
3. Kopo ea HPMC
Ka lebaka la sokoliana ea eona ea metsi a monate, chefo e tlase, le lipono tse ka fetohang, HPMC li sebelisoa haholo indastering e fapaneng.
Liipori tsa pharmaceticalical: Liibeng tsa pharmacceles, HPMC e sebelisoa haholo litokisetsong tse lokollotsoeng tsa lithethefatsi, liqhetsa tsa lepapa, li-gelding le likoloi tsa lithethefatsi. E ka thusa ho thusa lithethefatsi ka mokhoa o monate o qhibilihang metsing ebe o laola lebelo la ho lokolloa ha lithethefatsi.
Indasteri ea lijo: HpMC, joalo ka lijo tse eketsang lijo, hangata e sebelisoa bakeng sa emulssication, e totisa le ho mongobo le mongobo. Ka thepa e halikiloeng, e ka ntlafatsa ductionality le botsitso ba hlama. HPMC e boetse e sebelisoa ka ice cream, lino tse tahang le lijo tse fokolang.
Indasteri ea kaho: Indasteri ea kaho, HPMC e sebelisoa e le thipa ea ho haha seretse sa kaho, e ka ntlafatsang ts'ebetso ea kaho, ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi le ho boloka metsi.
Li-cosmetics: Litsela, lentšupa o tšoanang le o ne o sebelisoa haholo e le bolokolohi, 'me e sebelisoa haholo lihlahisoa tsa sefahleho joalo ka litlolo tsa sefahleho
HpmcNa ho qhibiliha ka metsi le ho etsa lintho tse ngata haholo tse sebetsang ka metsing tse ka bangkang tharollo e pepeneneng ka metsing. Ha se ea sobeloang, empa e le seliba se phahameng sa lipalesa se ka qhibilihang metsing. Stubility ea eona e bonahatsoa haholo ka sello hantle ka metsing, empa o sa khathatse libenvents boholo ba manyolo. Litšobotsi tsena tsa HPMC li e sebelisoa haholo indastering e ngata, ho kopanyelletsa le megation, lijo, kaho, le litlolo.
