Carboxy Methyl Cellulose (CMC)
Nkọwa ngwaahịa
Sodium carboxymethyl cellulose, nke a makwaara dị ka carboxymethyl cellulose, CMC, bụ ụdị cellulose kachasị eji na nke a na-ejikarị eme ihe n'ụwa taa.Ọcha fibrous ma ọ bụ ntụ ntụ granular.Ọ bụ ihe nrụpụta cellulose nke nwere ogo glucose polymerization nke 100 ruo 2000. Ọ bụ enweghị isi, enweghị ụtọ, enweghị ụtọ, hygroscopic, na enweghị ike ime ya na ihe mgbaze organic.
Sodium carboxymethyl cellulose bụ dakọtara na ike acid ngwọta, soluble ígwè salts, na ụfọdụ ndị ọzọ ọla dị ka aluminum, mercury na zinc. ụfọdụ protein nwere ebubo nke ọma.
