Hydroxypropypropypropinyl Methylcelllulose (HPMC) e atisa ho eketsoa haholo indastering e fapaneng ho kenyelletsa kaho ea thepa ea eona e nang le mathata. Tšimong ea tlhahiso e ngata, HPMC e bapala karolo ea bohlokoa ho ntlafatsa thepa e kang thepa ea kaho, ho boloka metsi le ho senya metsi.
Pholoso ke boitsebiso bo fapaneng bo sebelisoang haholo ho ea ho khotsofatsa matloana, bophahamo le ba fana ka libaka tse boreleli bakeng sa mabota le siling. Ts'ebetso ea Ptripe ke ea bohlokoa ho fihlela liphetho tseo u li lakatsang mererong ea kaho, litlatsetso li sebelisoa ho ntlafatsa thepa ea eona. Hydroxypropypropinyl Methylcellll.
1. Kakaretso ea hydroxypropypropyL methylcellllll (HPMC):
HPMC ke tšenyo ea cellulose ea celluulose, e bolokiloeng ka lihlopha tsa hydroyl of celdulese ea celdulese ea celdroxy le hydropyl lihlopha tsa lihlopha. Phetiso ena ea lik'hemik'hale e fana ka thepa e ikhethang ea HPMC, e e etsang e sa qhibiliha metsing le ho khona ho theha tharollo e tsitsitseng ea colloidal. Tlhahiso e meru, HPMC e sebetsa e le bolo e le sehlōhō, e phehang metsi, e amang bocha thepa ea bohlooho le ho feta.
2.Recipe ea 2.
Ho kenyelletsa HPMC ho fumana lintlha tse betliloeng ho hloka hore e beke ka tieo ho tsamaisoa ka mokhoa o kang ho tsamaisa lintho Ho khetha sehlopha se loketseng sa HPMC ho bohlokoa ho fihlela tekanyo e loketseng lipakeng tsa ts'ebetso le thepa ea tšebetso. Ho feta moo, litšebelisano lipakeng tsa HPMC le metsoako e meng e kang lifilimi, mebala le li-asper tse lokelang ho hlahlojoa le ho ntlafatsa ts'ebetso.
3. Tšoere ka ts'ebetso:
E 'ngoe ea melemo e kholo ea HPMC ka litlhahiso tse bulehileng ke bokhoni ba eona ba ho ntlafatsa ts'ebetso ka ho fetola thepa ea litlolo tsa borui. HPMC e sebetsa joalo ka thipa, e eketsa visecosity ea pampiri e ncha le ho fokotsa ho thella kapa ho theola nakong ea kopo. Mefuta ea pseudoplane ea tharollo ea HPMC e nolofatsang ho phatloha habonolo, ka mokhoa o bonolo oa ho ba le kahlolo e molemo le ho etsa mosebetsi ka kakaretso maemong a fapaneng a kaho.
4. Tšoereng thepa ea mochini:
Ho eketsoa ha HPMC ho ka ama thepa ea mochini oa litopo, matla a hodea, matla le matla a ho fetoha le maemo le matla a ho ferekana le matla a ho fetoha le maemo. HPMC e theha filimi e tšesaane holim 'a likaroloana tsa lifilimi, tse sebetsang e le khokhothelo lipakeng tsa likaroloana lipakeng tsa likaroloana. Sena se eketsa puithesion ka har'a matrix ea litoropong hape e eketsa ho hanyetsa le ho etsa. Ntle le moo, HPMC e thusa ho theha likokoana-hloko tse teteaneng, ka tsela eo o ile a ntlafatsa thepa e nang le matla a kang a sithabetsang le ho halefa.
5. Etsang sesupo:
Ho tšoarella ke karolo ea bohlokoa ea ts'ebetso ea tlhophiso, haholo likopo tse fumanehang ka ntle ho lebaka la mabaka a tikoloho, radiation ea UV li ka nyenyefatsa boitsebiso ka mor'a nako. HPMC e bapala karolo ea bohlokoa ho ntlafatsa botumo ba ho ntlafatsa khatello ea metsi, ho hana ha boemo ba moea le ho hana ho hola likokoana-hloko. Fydrophilic TAME ea HPMC e e lumella ho boloka mongobo matrixt, ho thibela ho otlolla metsi le ho fokotsa kotsi ea mapetso a shrinnkage. Ntle le moo, HPMC e theha filimi e sirelletsang holim'a polasetiki, e thibelang mongobo hore e se ke oa kena le tlhaselo ea lik'hemik'hale, ka tsela e ka etsang lik'hale ka tsela ea ho kena.
6. Mehopolo ea tikoloho:
Lilemong tsa morao tjena, ho bile le thahasello e matla ea ho hola thepa ea meaho e nang le tikoloho e fanang ka tšusumetso ea tikoloho. HPMC e fana ka melemo e 'maloa ntlheng ena, joalo ka ha e nkoa e le lisebelisoa tse ncha tse hatisitsoeng ebile e le livideo tlasa maemo a matle. Ka hona, tšebeliso ea HPMC ka litlhahiso tse bulehileng e eketsa katleho ea lintho tse bonahalang ebe e fokotsa ho boloka matla le lisebelisoa. Leha ho le joalo, tšusumetso eohle ea bophelo ea bophelo ba HPMC-e nang le lintho tse kang lits'ebetso tsa thepa, lipalangoang, li tlameha ho tšohloa ho lekola ka botlalo.
Hydroxypropypropypropinyl Methylcelll. Bokhoni ba HPMC ba ho fetola thepa ea Rheological, ntlafatsa thepa le ho ntlafatsa thepa ea ho ntlafatsa le ho ntlafatsa tlhokahalo ea likhakanyo tsa boleng bo holimo. Leha ho le joalo, ho fihlela ts'ebetso e nepahetseng ho hloka ho thetsa ka tlhokomelo e hloahloa, nahana ka lintlha tse kang karolelano ea sehlopha, ho lumellana le mabaka le mabaka le maemo a tikoloho le tikoloho. Ho hlokahala lipatlisiso tse ling ho hlahloba lits'ebetso tse ncha tsa HPMC ka liforomo tsa matla le ho sebetsana le liphephetso tse tsoang litloaelong tsa kaho tse sebetsang.
