Faa'iidooyinka Heerka Daawada ee HPMC

HPMC waxa ay noqotay mid ka mid ah dawooyinka aadka looga isticmaalo gudaha iyo dibaddaba,sababta oo ah HPMC waxa ay leedahay faa'iidooyin aanay lahayn dawooyinka kale.

1. Biyo milanka

Ku milmay biyo qabow oo ka hooseeya 40 ° C ama 70% ethanol, asal ahaan aan lagu milmin biyaha kulul ee ka sarreeya 60 ° C, laakiin wuu dhalaali karaa.

2. Kiimikada firfircoonaanta

HPMC waa nooc aan ionic ahaynether cellulose. Xalkeedu ma laha lacag ionic ah mana la falgalato cusbada birta ah ama xeryahooda organic ionic. Sidaa darteed, wax-soo-saarka kale kama falcelinayaan inta lagu jiro habka diyaarinta.

3. Xasilooni

Aad bay u deggan tahay aashitada iyo alkali, waxaana lagu kaydin karaa wakhti dheer inta u dhaxaysa pH 3 iyo 11 iyada oo aan isbeddel muuqda laga helin viscosity. Xalka aqueous ee HPMC waxa uu leeyahay saamaynta anti-mildew oo ilaalin kara xasiloonida viscosity wanaagsan inta lagu jiro kaydinta muddada-dheer. Xasiloonida tayada daawooyinka loo isticmaalo HPMC sida diyaarinta waxay ka fiican tahay daawooyinka loo isticmaalo walxaha dhaqameed (sida dextrin, istaarijka, iwm.).

4. viscosity la hagaajin karo

Noocyada viscosity ee kala duwan ee HPMC waa la isku dari karaa iyadoo loo eegayo saamiyo kala duwan, oo mawjaddeeduna way isbeddeli kartaa si waafaqsan xeerar gaar ah, waxayna leedahay xiriir toosan oo wanaagsan, sidaas darteed saamiga waxaa lagu dooran karaa shuruudaha. 2.5 Metabolism inert HPMC laguma nuugo ama metabolized ee jirka, oo ma bixiso kuleyl, sidaas darteed waa badbaado ah diyaarinta dawooyinka excipient. .

5. Amniga

HPMC waxaa guud ahaan loo arkaa wax aan sun ahayn oo aan xanaaq lahayn.
