Wershada saabuunta alaabta ceeriin cellulose Warshadaha Kiimikada HPMC cellulose ether Hydroxypropyl methyl cellulose

1) Muuqashada: HPMC waa ether nonionic cellulose, budo cad cawlan-cad ama granule, aan ur iyo dhadhan lahayn, milmay gudaha

biyo qabow, glacial acetic acid, ethanol, methanol iyo propylene glycol, wax yar ku milmay acetone iyadoo ku xidhan heerka

beddelka, ficil ahaan aan lagu milmi karin biyaha kulul, ethylene glycol iyo toluene. HPMC waxa lagu milmaa isku dar ah 10% methanol

iyo 90% chloride methylene si loo sameeyo xalal kolloidal ah.
2) Xalka HPMC wuxuu leeyahay dhaqdhaqaaq dusha sare ah, daahfurnaan sare, iyo waxqabad xasilloon. Marka lagu kululeeyo heerkul gaar ah

xalku wuxuu noqdaa daruuro ama wuxuu sameeyaa jel flocculent ah. Si kastaba ha noqotee, xalku wuxuu noqdaa mid cad mar kale qaboojinta ka dib. Noocyada kala duwan ee

HPMC waxay leeyihiin heerkul-kulul oo kala duwan. Solubilityku wuu ku kala duwan yahay viscosity. Hooska viscosity, ayaa ah mid aad u sarreeya

waxeey heesataa. Noocyada kala duwan ee HPMC way ku kala duwan yihiin guryaha qaarkood oo milmayntooda biyaha ma saamayso pH.
3) Cabbirrada walxaha: 100% heerka gudbinta 80 mesh.
4) Cufnaanta muuqata: 0.25-0.70 g/mL (badanaa qiyaastii 0.5 g/ml), cufnaanta gaarka ah 1.26-1.31mL.
5) heerkulka isbeddelka midabka: 190-200 ° C; Heerkulka karbonaynta:280-300°C.
6) Xiisadda dusha sare:42-56 dyn/cm (2% xal aqueous).
7) Maadada methoxy ee sare ee HPMC, heerkulka gelation hoose, iyo milanka sare ee biyaha iyo dhaqdhaqaaqa dusha sare.
8) HPMC waxay leedahay astaamo kale, tusaale ahaan, hantida dhumucdeeda, xasiloonida pH, haynta biyaha, samaynta filim heer sare ah

hantida, kala firdhisan wanaagsan iyo awoodda adhesion.
