Sodium carboxymethyl cellulose (CMC) bụ ngwakọta nke nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche. Ngwongwo ya pụrụ iche na-eme ka ọ baa uru na ngalaba dịka nri, ọgwụ, ihe ịchọ mma, textiles na ọtụtụ ndị ọzọ.
1. Okwu Mmalite na Sodium Carboxymethyl Cellulose (CMC)
Sodium carboxymethyl cellulose, nke a na-akpọkarị CMC, bụ polymer soluble mmiri nke sitere na cellulose, polysaccharide na-emekarị nke a chọtara na mgbidi cell osisi. A na-emepụta ya site n'ịgwọ cellulose na sodium hydroxide na monochloroacetic acid ma ọ bụ nnu sodium ya. Mgbanwe a na-agbanwe usoro cellulose, na-ewebata otu carboxymethyl (-CH2COOH) iji welie mmiri solubility ya na ihe ndị ọzọ na-achọsi ike.
2. Njirimara nke sodium Carboxymethyl Cellulose
Mmiri Solubility: CMC bụ nke ukwuu soluble na mmiri, na-eme viscous ngwọta ọbụna na obere mkpokọta. Ngwongwo a na-eme ka ọ dabara maka ngwa dị iche iche ebe achọrọ ike ịgbatị, nkwụsi ike, ma ọ bụ ike ijikọ.
Njikwa viscosity: Ngwọta CMC na-egosipụta omume pseudoplastic, nke pụtara viscosity ha na-ebelata n'okpuru nrụgide siri ike. Ihe onwunwe a na-enye ohere ijikọta ngwa ngwa na ngwa dị iche iche.
Ikike imepụta ihe nkiri: CMC nwere ike mepụta ihe nkiri doro anya, na-agbanwe agbanwe mgbe a na-etinye ya na ngwọta. Njirimara a na-achọta ngwa na mkpuchi, nkwakọ ngwaahịa, na usoro ọgwụ.
