Qaab dhismeedka kiimikaad ee soosaarayaasha ether cellulose

Ethers-ka Cellulose waa unugyo cellulose, polysaccharide dabiici ah oo laga helo gidaarada unugyada dhirta. Qaab dhismeedka kiimikada ee ethers cellulose waxaa lagu gartaa hordhaca kooxo kala duwan oo ether ah iyada oo loo marayo hagaajinta kiimikada ee kooxaha hydroxyl (-OH) ee ku jira molecule cellulose. Noocyada ugu caansan ee ether-ka cellulose waxaa ka mid ah:

1. Hydroxypropyl Methylcellulose (HPMC):
   • Qaab dhismeedka:
     • HPMC waxa lagu soo kordhiyey iyada oo lagu beddelayo kooxaha hydroxyl ee cellulose labadaba hydroxypropyl (-OCH2CHOHCH3) iyo methyl (-OCH3).
     • Heerka beddelka (DS) ayaa tilmaamaya tirada celceliska ee kooxaha hydroxyl ee la beddelay unugga gulukooska ee silsiladda cellulose.
2. Carboxymethyl cellulose(CMC):
   • Qaab dhismeedka:
     • CMC waxaa soo saaray iyadoo la soo bandhigayo kooxaha karboxymethyl (-CH2COOH) kooxaha hydroxyl ee cellulose.
     • Kooxaha carboxymethyl waxay siiyan milanka biyaha iyo dabeecada anionic silsiladda cellulose.
3. Hydroxyethyl Cellulose (HEC):
   • Qaab dhismeedka:
     • HEC waxaa laga soo qaatay iyadoo lagu beddelayo kooxaha hydroxyl ee cellulose iyadoo lagu beddelayo kooxaha hydroxyethyl (-OCH2CH2OH).
     • Waxa ay muujisaa milanka biyaha oo hagaagay iyo sifooyinka dhumucdooda.
4. Methyl Cellulose (MC):
   • Qaab dhismeedka:
     • MC waxa la soo saaray iyada oo la soo bandhigayo kooxaha methyl (-OCH3) kooxaha hydroxyl ee cellulose.
     • Waxaa caadi ahaan loo isticmaalaa haynta biyaha iyo sameynta filimada.
5. Ethyl Cellulose (EC):
   • Qaab dhismeedka:
     • EC waxaa lagu sameeyay iyadoo lagu bedelayo kooxaha hydroxyl ee cellulose iyadoo lagu bedelayo kooxaha ethyl (-OC2H5).
     • Waxaa lagu yaqaanaa inay ku milmi la'dahay biyaha waxaana badanaa loo isticmaalaa soo saarista dahaarka iyo filimada.
6. Hydroxypropyl Cellulose (HPC):
   • Qaab dhismeedka:
     • HPC waxaa lagu soo bandhigaa kooxaha hydroxypropyl (-OCH2CHOHCH3) kooxaha hydroxyl ee cellulose.
     • Waxa loo istcimaalaa sidii binder, filim hore, iyo wax ka beddelka viscosity.

Qaab dhismeedka gaarka ah wuxuu ku kala duwan yahay derivative cellulose ether kasta oo ku salaysan nooca iyo heerka beddelka ee la soo bandhigay inta lagu jiro habka wax ka beddelka kiimikada. Soo bandhigida kooxahan ether-ka waxay siinayaan hanti gaar ah ether kasta oo cellulose ah, taasoo ka dhigaysa inay ku habboon yihiin codsiyada warshadaha kala duwan.
