HPMC (HydroxypropypropypropyLe Methylcellwalo) le Hydroxeeyyl
1. Phapang ka sebopeho sa lik'hemik'hale
HPMC LE HEC
HPMC (HydroxypropypropyL methylcellOlose): HPMC e fumanoa ka bosholu ba Hydroulll (-ch₂) Tekanyo ea sebaka sa lithyl le sa hydropypropyl e khetha thepa ea HPMC.
Hec (hydroxeeyl cellulouse): Hec ke ether e le e tsoang ka mll celdroxey "
Phapang ena ka sebopeho sa lik'hemik'hale e ama sello ka kotloloho, pono le thepa e 'ngoe ea lik'hemik'hale le lik'hemik'hale.
2. Maemo a qhobosheane le a qhibilihang
HPMC: HPMC e na le qubu e ntle ea metsi mme e ka qhibiliha ka metsing a batang ho etsa tharollo ea li-viscous tse pepenoang. E ka boela ea qhibiliha libakeng tse nang le li-shost, Acetone, Etc. Karolo ea bohlokoa ea HPMC ke hore e qhibiliha ka metsing a batang, athe nakong ea ho futhumatsa tharollo ea mocheso (e fetoha gel ha e futhumatsoa ebile e qhalane ha e futhumatsa). Thepa ena e bohlokoa haholo masimong a joalo ka kaho le bokooa.
Hec: hec e boetse e qhibiliha ka metsing a batang, empa ho fapana le HPMC, Hec ha e tšoele ka metsing a chesang. Ka hona, hec e ka sebelisoa holim'a mocheso o pharaletseng. Hec o na le mamello e matla ea letsoai le e matla ebile e loketse ho sebelisoa tharollong e nang le li-elektrone.
3. Litaba tsa liketsahalo tsa Viscosity le tsa Rheology
Litaba tsa HPMC le Shec li fapana ka boima ba tsona ba limok'hule, 'me ka bobeli li na le litlamorao tse ntle tsa mahloriso.
HPMC: HPMC e bonts'a lintho tse phahameng tsa pseudoplat (ke hore, thepa e tšesaane-e nonneng) ka tharollo. Litsie tsa HPMC li fokotseha ha Sheare ea eketseha, litlolo tsa litlolo tsa HPMC li fokotseha ka mocheso o itseng, 'me setlamo sa HPMC se fokotseha ka mocheso o itseng.
Hec: Litharo tsa Hec li na le liketsahalo tse phahameng le tse ntle tsa litheko tse tlase, ho bonts'a thepa ea phallo ea Newtonian (ke hore khatello ea kelello e lekana le sekhahla sa shear). Ntle le moo, litharollo tsa hec li na le liphetoho tse nyane tsa pono tikolohong e nang le matsoalo le litlolo tse ngata, hape li na le letsoai le letle la letsoai. Li sebelisoa haholo masimong a hlokang ho hana letsoai, joalo ka tšebeliso ea oli le kalafo ea seretse.
4. Phapang maemong a kopo
Leha maqhomba le hec li ka sebelisoa e le lidelo, liprofeame, fantisi ea lifilimi, litekanyetso tsa bona libakeng tse khethehileng tsa kopo li fapane:
Likopo tsa HPMC:
Indasteri ea kaho: HPMC e sebelisoa e le moemeli le boikemisetso ba metsi le meaho ea metsi masimong a thepa ea meho e kang salersare e kang samer. E ntlafatsa mosebetsi oa sereko, ha a qhekella ho tsamaea, le ho mo leleka nako e bulehileng ea seretse.
Mekhabiso ea meriana le ea lijo: Bongaka, HPMC hangata e sebelisoa e le lisebelisoa tsa ho koahela litafole tsa matlapa le lisebelisoa tsa litokisetso tse lokollotsoeng. Indastering ea lijo, HPMC e sebelisoa e le lijo tse eketsang lijo, haholo-holo joaloka emongkifier, thickener le hlorisi.
Indebrary Dailm ea lik'hemik'hale: HPMC e sebelisoa e le setiba se hloahloa, thickener le ho sireletsa motsoako oa lifilimi le lihlahisoa tsa tlhokomelo ea motho.
Likopo tsa Hc:
Nts'etsopele ea oli: Kaha hec e na le mamello e matla ho letsoai, e loketse haholo ho sebelisoa e le moemeli oa letsoai bakeng sa ho chencha letsoai le phahameng ho ntlafatsa lipehelo tsa litlolo tsa seretse sa seretse.
Indasteri ea ho apara: Hec e sebelisoa e le tlheketla le ho hlonepha ka mabaka a thehiloeng metsing. E ka ntlafatsa phara le ts'ebetso ea kaho ea koluoa le ho thibela koae ka ho sesa.
Indasteri ea pampiri le masela: hec e ka sebelisoa bakeng sa ho tela lipampiring tsa pampiri le kalafo indastering ea machankane e tiisa, 'me e hlophise lintho tsa rusoogical.
5. Ho tsitsa tikoloho le botsitso
HPMC: HPMC e sebelisoa hangata masimong a pharmacEa ona le ea lijo ka lebaka la biocondomatic ho lokile le biodegradadical. Mabaka a eona a li-grealing a li-grealing a boetse a fana ka melemo e ikhethang litlharelong tse ling tsa mocheso. Ntle le moo, HPMC ha e ratehe, e sa angoe ke li-elektrone, 'me e tsitsitse ho li fetoha hantle.
Hec: hec le eona e na le biocompatice e ntle le biodegradadity, empa e bontša ho tsitsipalla libakeng tse ngata. Ka hona, Hec ke khetho e ntle moo ho hanyetsang letsoai le ho hanyetsana la motlakase ho hlokahala, joalo ka ho hlahloba mosebetsi oa oli, jj. Boenjiniere ba oli, jj.
6. Litšenyehelo le phepelo
Ho tloha hpmc le hec ba nkiloe ka mpeng ea tlholeho, phepelo ea lisebelisoa tse tala e tsitsitse, empa ka lebaka la lits'ebetso tsa tlhahiso e fapaneng, litšenyehelo tsa HPM li phahame hanyane ho feta tsa Hec. Sena se etsa hore a sebelisoe haholo likolong tse ling tse hlokofatsang tse theko e phahameng, joalo ka lisebelisoa tsa kaho, lik'hemik'hale tsa tšimo ea oli, jj.
HPMC LE HEC ke lintho tse ling tsa bohlokoa tsa cellulose. Le ha li fapane ka sebopeho sa lik'hemik'hale, bobeli ba bona ba na le mesebetsi e kang e toba, tšebeliso ea moea le ho etsa lifilimi. Mabapi le khetho e ikhethileng ea ts'ebeliso, HPMC e lula boemong ba bohlokoa kahong, ho itukisetsa ho itukisetsa mesebetsi le khoebo ea lijo ka lebaka la li-grolling tsa eona tse khethehileng tsa mocheso; Ha aec a bapala karolo ea bohlokoa indastering ea peroleum ka lebaka la mamello ea eona e ntle ea letsoai le mocheso oa eona o fetohileng. E molemo le ho feta ka har'a meepo le bosholu ba metsi. Ho latela litlhoko tse fapaneng tsa kopo, ho khetha litlolo tse loketseng cellulose li ka ntlafatsa melemo ea sehlahisoa le moruo.
