Ngwongwo na Mmepụta nke SCMC

Sodium Carboxymethyl Cellulose bụ ihe sitere na cellulose, nke bụ polymer na-emekarị nke mejupụtara nkeji glucose. A na-eme SCMC site na iji kemịkalụ a na-akpọ monochloroacetic acid na-agwọ cellulose, nke na-eme ka cellulose ghọọ carboxymethylated. Nke a pụtara na a na-agbakwunye otu carboxymethyl (-CH2-COOH) na ọkpụkpụ azụ cellulose, nke na-enye ya ihe ọhụrụ dị ka ụbara solubility n'ime mmiri na imeziwanye ike na-ejikọta na ike.
