Alaabta
Hydroxypropyl methyl cellulose oo loogu talagalay xabagta tile ee koollada sagxada loogu talagalay hagaajinta koollada dhoobada dhoobada ah ee la isticmaalay HPMC
Sharaxaada badeecada
Shuruudaha xabagta dhoobada dhoobada iyadoo loo marayo habka tooska ah:
●Karti wanaagsan, hawl fudud, mindi aan dheg lahayn
●adhesion bilow ah oo wanaagsan
Shuruuda sare ee xabagta tile marka habka koollada khafiifka ah:
●Si fudud loo shaqeeyo, fududahay in lagu shaqeeyo, mindi aan dheg lahayn
●Saameyn wanaagsan oo liddi ku ah
●Waqti dheer oo furitaanka, qoyaan wanaagsan
●Waqti dheer oo la hagaajin karo
Hababka dhismaha ee kala duwan ee shuruudaha binder ee kala duwan, waxaan ku siin karnaa alaabooyinka ether cellulose kala duwan si ay si fudud u buuxiyaan.Dongyuan cellulose waxay ku siin kartaa xabagta dhoobada leh adhesion qoyan oo aad u fiican, waxqabadka anti-sag iyo waqtiga furitaanka.
Alaabooyinka ether-ka ee Dongyuan cellulose waxay hubin karaan dhismaha siman ee noocyada kala duwan ee foornada dusha sare ee kala duwan, xitaa heerkulka deegaanka.
Astaamaha ugu muhiimsan ee hydroxypropyl methyl cellulose (HPMC)
1. Haysashada biyaha
Marka HPMC loo isticmaalo dusha walxaha nuugaya sida gidaarada, waxay leedahay sifooyin lagu yareeyo khasaaraha biyaha.
2. Biyo milmaya
HPMC waxay ku milmi kartaa biyo qabow, laakiin kuma milmi biyo kulul.
3. Dabiiciga dabiiciga ah
HPMC waxay leedahay koox hawleed hydrophobic gaar ah si ay u kala diri kartaa qayb ka mid ah binary organic iyo aqueous dareere.
4. xasiloonida PH
PH ee HPMC guud ahaan wuu xasiloon yahay inta u dhaxaysa 3.0-11.0, milanka HPMC waxa saameeya qiimaha PH
5. Beddel aan ahayn ionic
HPMC waxay la jaanqaadi kartaa waxyaabaha kale ee lagu daro xal aqueous ah, waxayna bixisaa isku darka biyaha-milmi kara deggan.
6. Dhumucda iyo ku dhegganaanta
HPMC waxay leedahay sifooyinka dhumucda iyo xoojinta adhesion.
7. Laalid
HPMC waxay wanaajin kartaa xasiloonida hakinta xalka.
8. Gel kuleyl
Marka heerkulku kor u kaco ilaa xad, HPMC xalku wuu dhalaali doonaa.Marka heerkulka xalku hoos u dhaco, ifafaalaha gelation-ka ayaa baaba'a.
9. Dufanka
Guryaha HPMC waxay wanaajin karaan dhismaha, wanaajin karaan sibidhka -base-ka-soo-saarka alaabta iyo waxqabadka dhoobada dhoobada ah.
10. Dhaqdhaqaaqa dusha sare
Guryaha dhaqdhaqaaqa dusha sare ee HPMC ayaa bixiya xalka looga baahan yahay kolloidka ilaalinta iyo emulsification.
11. Xubin
HPMC waxay samayn kartaa filim dabacsan oo hufan, oo si wax ku ool ah u xannibi kara dufanka.
12. Antimicrobial iyo caariyaysi u adkaysta
Kaydinta muddada-dheer, HPMC waxay si wax ku ool ah uga hortagi kartaa duulaanka bakteeriyada, si ay u hubiso xasiloonida viscosity wanaagsan.
13. Emulsification
HPMC ACTS sida emulsion xasiloonida xalkeeda.
