ʻO ka sodium carboxymethyl cellulose

ʻO ka sodium carboxymethyl cellulose (CMC-Na) kahi huaʻai carboxymethylated o ka cellulose a ʻo ia ka mea nui ionic cellulose gum.ʻO ka sodium carboxymethyl cellulose ka mea maʻamau he pūhui polymer anionic i hoʻomākaukau ʻia e ka hana ʻana i ka cellulose kūlohelohe me ka alkali caustic a me ka waikawa monochloroacetic, me ke kaumaha molekala mai nā tausani a i miliona.ʻO ka CMC-Na he fibrous keʻokeʻo a i ʻole ka pauka granular, ʻono ʻole, ʻono ʻole, hygroscopic, maʻalahi e hoʻopuehu i ka wai e hana i kahi hopena colloidal akaka.
