Kedu ihe bụ sodium cmc?

Sodium Carboxymethyl Cellulose (CMC) bụ polymer soluble mmiri nke sitere na cellulose, nke bụ polysaccharide na-emekarị nke a na-ahụ na mgbidi cell nke osisi. A na-emepụta CMC site n'ịgwọ cellulose na sodium hydroxide na monochloroacetic acid, na-ebute ngwaahịa nwere otu carboxymethyl (-CH2-COOH) jikọtara na ọkpụkpụ cellulose.

A na-ejikarị CMC eme ihe na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, nlekọta onwe onye, ​​na ngwa mmepụta ihe, n'ihi ihe ndị pụrụ iche ya. N'ime ngwaahịa nri, sodium CMC na-eje ozi dị ka ihe na-eme ka ọ sie ike, stabilizer, na emulsifier, na-eme ka udidi, nkwụsi ike, na ndụ nchekwa. N'ọgwụ ọgwụ, a na-eji ya dị ka ihe nkedo, disintegrant, na viscosity modifier na mbadamba nkume, nkwusioru, na ointments. N'ime ngwaahịa nlekọta onwe onye, ​​ọ na-arụ ọrụ dị ka ihe na-ejupụta, mmiri mmiri, na onye na-emepụta ihe nkiri na ihe ịchọ mma, ude mmiri, na ntacha eze. N'ime ngwa ụlọ ọrụ mmepụta ihe, a na-eji sodium CMC eme ihe dị ka onye na-ekekọta, rheology modifier, na onye na-ahụ maka nkwụsị mmiri n'ime agba, ncha, textiles, na mmiri na-egwupụta mmanụ.

A na-ahọrọ sodium CMC karịa ụdị CMC ndị ọzọ (dị ka calcium CMC ma ọ bụ potassium CMC) n'ihi nnukwu solubility na nkwụsi ike na ngwọta mmiri. Ọ dị na ọkwa dị iche iche na viscosities iji kwado ngwa dị iche iche na nhazi nhazi. N'ozuzu, sodium CMC bụ ihe mgbakwunye nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche.
