Sodium carboxymethylcellulose (CMC) bụ polymer bara ụba na nke nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche.Ngwa a sitere na cellulose, polymer eke dị na mgbidi cell osisi.A na-emepụta CMC site n'ịgbanwe cellulose na kemịkal site na iwebata otu carboxymethyl n'ime ọkpụkpụ azụ cellulose.Ihe na-akpata sodium carboxymethylcellulose nwere ihe pụrụ iche na-eme ka ọ baa uru n'ọtụtụ ngwa.
Ọdịdị Molecular:
Ọdịdị molekụla nke sodium carboxymethylcellulose nwere ọkpụkpụ azụ cellulose nwere otu carboxymethyl (-CH2-COO-Na) jikọtara ụfọdụ otu hydroxyl na nkeji glucose.Mgbanwe a na-enye solubility na ihe ndị ọzọ bara uru na polymer cellulose.
Solubility na ihe ngwọta:
Otu n'ime ihe ndị bụ isi nke CMC bụ mmiri solubility ya.Sodium carboxymethyl cellulose na-adị mfe soluble na mmiri na-etolite a transperent viscous ngwọta.Enwere ike idozi solubility site n'ịgbanwe ogo nke nnọchi (DS), nke bụ nkezi ọnụọgụ nke otu carboxymethyl otu glucose n'ime agbụ cellulose.
Njirimara rheological:
Omume rheological nke ngwọta CMC bụ ihe kwesịrị ịrịba ama.The viscosity nke CMC ngwọta na-abawanye na-amụba itinye uche na ike dabere na ogo nke nnọchi.Nke a na-eme ka CMC bụrụ ihe dị irè na ngwa dị iche iche, gụnyere nri, ọgwụ na usoro mmepụta ihe.
Njirimara ion:
Ọnụnọ nke ion sodium na otu carboxymethyl na-enye CMC agwa ion ya.Ụdị ionic a na-enye ohere CMC ka ya na ụdị ebubo ndị ọzọ na-emekọrịta ihe na ngwọta, na-eme ka ọ baa uru na ngwa ndị chọrọ njikọ ma ọ bụ nhazi gel.
Mmetụta pH:
Na solubility na ihe onwunwe nke CMC na-emetụta pH.CMC nwere solubility kachasị elu ma gosipụta arụmọrụ ya kacha mma n'okpuru ọnọdụ obere alkaline.Otú ọ dị, ọ na-anọgide na-eguzosi ike n'elu nnukwu pH, na-enye mgbanwe maka ngwa dị iche iche.
Njirimara mmepụta ihe nkiri:
Sodium carboxymethylcellulose nwere ikike imepụta ihe nkiri, na-eme ka ọ dabara maka ngwa chọrọ imepụta ihe nkiri dị mkpa ma ọ bụ mkpuchi.Enwere ike iji ihe onwunwe a mepụta ihe nkiri oriri, ihe mkpuchi mbadamba, wdg.
Hazie:
CMC kwụsiri ike n'okpuru ọnọdụ gburugburu ebe obibi dị iche iche, gụnyere mgbanwe okpomọkụ na pH.Nkwụsi ike a na-enye aka na ogologo ndụ ya na ịdị mma maka ọtụtụ ngwa.
Emulsion stabilizer:
CMC na-arụ ọrụ dị ka emulsifier dị irè ma na-enyere aka mee ka emulsions guzosie ike na nri na ihe ịchọ mma.Ọ na-eme ka nkwụsi ike nke emulsions mmanụ-n'ime mmiri dị mma, na-enyere aka melite ogo zuru oke na ndụ ndụ nke ngwaahịa ahụ.
Ndokwa mmiri:
N'ihi ike ya ịmịnye mmiri, a na-eji CMC eme ihe dị ka onye na-ejigide mmiri na ụlọ ọrụ dị iche iche.Ihe onwunwe a bara uru nke ukwuu maka ngwa dị ka textiles, ebe CMC na-enyere aka ịnọgide na-enwe mmiri nke akwa akwa n'oge usoro dị iche iche.
Nkwalite ndụ:
A na-ewere sodium carboxymethylcellulose dị ka ihe na-emebi emebi n'ihi na o sitere na cellulose, polymer na-emekarị.Njirimara a dị ezigbo mma na gburugburu ebe obibi ma kwekọọ n'ọchịchọ na-eto eto maka ihe ga-adigide n'ofe ụlọ ọrụ.

A na-eji CMC eme ihe dị ka ihe mkpuchi akwụkwọ iji meziwanye ike na mbipụta akwụkwọ.
Ọ na-arụ ọrụ dị ka ihe enyemaka njide na usoro nhazi akwụkwọ.
Ngwaahịa nlekọta onwe onye:
A na-achọta CMC na ngwaahịa nlekọta onwe onye dị iche iche dị ka ntacha eze na ncha ntutu dị ka ihe na-eme ka ọ dị arọ na ihe nkwụsi ike.
Ọ na-enye aka na nhazi zuru oke na nkwụsi ike nke usoro ịchọ mma.
