Astaamaha iyo Codsiyada Hydroxyethyl Methyl Cellulose HEMC

Astaamaha ugu muhiimsan eeHydroxyethyl methyl cellulose (HEMC)waa:

1. Solubility: ku milmay biyaha iyo qaar ka mid ah dareerayaasha organic, HEMC waxaa lagu milmi karaa biyo qabow, xoojinta ugu badan waxaa lagu go'aamiyaa oo kaliya by viscosity, solubility kala duwan yahay viscosity, hoose viscosity, ka weyn ee milanka.

2. Cusbada iska caabbinta: Alaabooyinka HEMC waa kuwa aan-ionic cellulose ethers ah oo aan ahayn polyelectrolytes, markaa joogitaanka cusbada birta ah ama electrolytes organic, waxay ku xasilan yihiin xalalka aqueous, laakiin ku darida xad-dhaafka ah ee electrolytes waxay keeni kartaa gelation iyo roobab.

3. Dhaqdhaqaaqa dusha sare: Sababtoo ah xalka aqueous wuxuu leeyahay hawlqabad dusha sare ah, waxaa loo isticmaali karaa sida wakiilka difaaca kolloid, emulsifier iyo kala firdhiye.

4. Gel kuleyl: MarkaHEMCXalka aqueous ee badeecada ayaa lagu kululeeyaa heerkul gaar ah, wuxuu noqdaa mid mugdi ah, jeel ah, wuxuuna sameeyaa roobab, laakiin marka si joogto ah loo qaboojiyo, waxay ku noqotaa xalalka asalka ah, iyo jelkan iyo roobka ayaa dhacaya. Heerkulka inta badan wuxuu ku xiran yahay saliidaha ay ku jiraan, kaaliyeyaasha joojinta, kolloysyada ilaalinta, emulsifiers, iwm.

5. Dheef-shiid kiimikaad iyo ur yar iyo udgoon: HEMC si weyn ayaa loogu isticmaalaa cuntada iyo daawada sababtoo ah maaha mid dheef-shiid kiimikaad ah oo leh ur iyo udgoon yar.

6. Antifungal: HEMC waxay leedahay awood antifungal wanaagsan iyo xasilloonida viscosity wanaagsan inta lagu jiro kaydinta muddada dheer.

7. Xasiloonida PH: Viscosity of the HEMC sheyga xal aqueous si dhib leh u saameeyaa aashitada ama alkali, iyo qiimaha pH waa mid deggan inta u dhaxaysa 3.0-11.0.

CodsigaHydroxyethyl methyl cellulose (HEMC)：

Hydroxyethyl methyl cellulose waxaa loo isticmaali karaa sida wakiilka ilaalinta kolloid, emulsifier iyo kala firdhiso ay sabab u tahay ay dusha shaqada firfircoon ee xal aqueous. Tusaale ahaan codsigeeda waa sida soo socota: Saamaynta hydroxyethyl methyl cellulose ee sifooyinka sibidhka. Hydroxyethyl methyl cellulose waa budo cad oo aan ur lahayn, dhadhamin, aan sun ahayn oo ku milma biyo qabow si ay u sameeyaan xal cad oo muuqda. Waxay leedahay sifooyinka dhumucda, xidhidhiyaha, kala firdhiyo, emulsifying, film samaynta, laalista, adsorbing, gelling, dusha-firfircoon, ilaalinta qoyaan iyo ilaalinta kolloidyada. Sababtoo ah shaqada firfircoon ee dusha sare ee xalka aqueous, waxaa loo isticmaali karaa sida wakiilka ilaalinta kolloid, emulsifier iyo kala firdhiso. Hydroxyethyl methyl cellulose xal aqueous ah ayaa leh biyo nadiif ah oo wanaagsan waana wakiil biyo-hayn ah oo tayo sare leh.
