Ku milmay biyaha iyo qaar ka mid ah dareerayaasha organic waxaa lagu milmi karaa biyo qabow, diiraddeeda ugu badan waxaa lagu go'aamiyaa kaliya viscosity, milmayntu waxay isbeddelaysaa viscosity, hoose ee viscosity, way sii weynaataa.
Iska caabinta milixda: Hydroxypropyl methylcellulose ee dhismaha waa ether-ka cellulose-ka aan-ionic ahayn ee ma aha polyelectrolyte, markaa way xasilloon tahay xalalka aqueous marka cusbada birta ah ama electrolytes organic ay jiraan, laakiin ku darida xad-dhaafka ah ee electrolytes waxay keeni kartaa xabagta iyo roobka.
Dhaqdhaqaaqa dusha sare: sababtoo ah shaqada firfircoon ee dusha sare ee xalka aqueous, waxaa loo isticmaali karaa sida wakiilka ilaalinta kolloidal, emulsifier iyo kala firdhiso.
Marka la kululeeyo heerkul gaar ah, xalka aqueous ee hydroxypropyl methylcellulose ee dhismaha kuleylku wuxuu noqdaa mid mugdi ah, jel, iyo roobab, laakiin marka si joogto ah loo qaboojiyo, waxay ku soo noqotaa xalalka asalka ah, iyo uumigani wuu dhacaa.Heerkulka xabagta iyo roobabku waxay inta badan ku xidhan yihiin saliidaha, wakiilada joojinta, kolloysyada ilaalinta, emulsifiers, iwm.
Tilmaamaha Alaabta
Ka-hortagga caarada: Waxay leedahay awood ka-hortagga caariyaysiga oo aad u wanaagsan iyo xasilloonida viscosity wanaagsan inta lagu jiro kaydinta muddada-dheer.
Xasiloonida PH: Viscosity of hydroxypropyl methylcellulose xal aqueous ee dhismaha si dhib leh u saameeyaa aashitada ama alkali, iyo qiimaha pH waa mid deggan inta u dhaxaysa 3.0 ilaa 11.0.Haysashada qaabka Sababtoo ah xalka aadka u uruursan ee hydroxypropyl methylcellulose ee dhismaha wuxuu leeyahay sifooyin gaar ah oo viscoelastic ah marka la barbar dhigo xalalka aqueous ee polymers kale, ku-darkeedu wuxuu hagaajin karaa awoodda lagu ilaaliyo qaabka alaabta dhoobada ah ee extruded.
Haysashada biyaha: hydroxypropyl methylcellulose ee dhismuhu wuxuu leeyahay hydrophilicity iyo viscosity sare ee xalkeeda aqueous, taas oo ah wakiilka biyaha ee waxtarka sare leh.
Guryaha kale: dhumuclaha, wakiilka filimada-samaynta, binder, lubricant, wakiilka suspending, kolloid ilaalinta, emulsifier, iwm.
