Astaamaha Sodium Carboxymethyl Cellulose
CMC waa derivative cellulose oo leh heerka gulukoosta polymerization ee 200-500 iyo heerka etherification ee 0.6-0.7.Waa budo cad ama ka baxsan ama walax fibros ah, aan ur lahayn iyo hygroscopic.Heerka beddelka kooxda carboxyl (shahaadada etherification) ayaa go'aamisa hantideeda.Marka heerka etherification uu ka sarreeyo 0.3, waxay ku milmi kartaa xalalka alkali.Viscosity ee xalka aqueous waxaa lagu go'aamiyaa pH iyo heerka polymerization.Marka heerka etherification uu yahay 0.5-0.8, kuma soo degi doono aashitada.CMC si sahal ah ayay ugu milmi kartaa biyaha waxayna noqotaa xal hufan oo biyaha ku jira, viscosity-kiisuna wuu kala duwan yahay iyadoo la eegayo xoojinta xalka iyo heerkulka.Heerkulku wuu xasiloon yahay oo ka hooseeya 60 ° C, mawjadaha ayaa yaraan doona marka la kululeeyo wakhti dheer heerkul ka sarreeya 80 ° C.
Baaxadda isticmaalka sodium carboxymethyl cellulose
Waxay leedahay hawlo kala duwan sida dhumucdi, hakin, emulsifying iyo xasilinta.Soosaarka cabitaanka, waxa inta badan loo isticmaalaa sidii dhumucyo cabitaanada casiirka nooca saxarka ah, sida emulsification emulsification ee cabitaanada borotiinka iyo xasiliya cabbitaannada caano fadhi.Qiyaasta guud ahaan waa 0.1%-0.5%.
