Sodium Carboxymethyl Cellulose Formula
Qaabka kiimikada ee sodium carboxymethyl cellulose (CMC) waxaa loo matalli karaa sida
(C6H10O5) n CH2COONa, halkee
n waxay ka dhigan tahay tirada unugyada gulukooska ee silsiladda cellulose.
Erayada fudud, CMC waxa ay ka kooban tahay unugyo cellulose ah oo soo noqnoqda, kuwaas oo ka kooban gulukoos molecules (
C6H10O5), oo leh kooxaha karboxymethyl (-CH2COONa) oo ku xidhan qaar ka mid ah kooxaha hydroxyl (-OH) ee unugyada gulukooska. "Na" waxay ka dhigan tahay sodium ion, kaas oo la xidhiidha kooxda karboxymethyl si ay u sameeyaan cusbada sodium ee CMC.
Qaab dhismeedkan kiimikaad wuxuu siinayaa sodium carboxymethyl cellulose sifooyinkeeda biyo-milmi kara iyo wax-qabad, taasoo ka dhigaysa polymer-ka-badan ee loo isticmaalo warshadaha kala duwan ee dhumucda, xasilinta, iyo wax ka beddelka sifooyinka rheological ee qaababka.
