Sodium carboxymethylcellulose (NaCMC) bụ ihe na-emepụta cellulose dị iche iche na nke na-achọta ngwa n'ime ụlọ ọrụ dị iche iche n'ihi njirimara pụrụ iche ya. Ngwa a sitere na cellulose, polymer eke dị na mgbidi cell osisi. A na-emepụta sodium carboxymethyl cellulose site n'imeghachite cellulose na sodium monochloroacetate na neutralize ya. Ngwaahịa ndị a na-esi na ya pụta nwere ọtụtụ ihe ndị a na-achọsi ike, na-eme ka ha baa uru na nri na ihe ọṅụṅụ, ọgwụ, ihe ntecha, textiles na ndị ọzọ.
Nhazi na mejupụtara:
Sodium carboxymethyl cellulose bụ polymer soluble mmiri nke nwere usoro ahịrị. A na-agbanwe ọkpụkpụ azụ cellulose site na otu carboxymethyl nke ewepụtara site na etherification. Ogo nke nnọchi (DS) na-ezo aka na nkezi ọnụọgụ nke otu carboxymethyl kwa otu anhydroglucose na agbụ cellulose. DS na-emetụta nke ọma ihe anụ ahụ na kemịkal nke NaCMC.
Usoro mmepụta:
Mmepụta nke sodium carboxymethylcellulose gụnyere ọtụtụ usoro. A na-enwetakarị cellulose site na pulp osisi ma ọ bụ owu, a na-emezi ya ka ọ wepụ ihe adịghị ọcha. Ọ na-emeghachi omume na sodium monochloroacetate n'okpuru ọnọdụ alkaline iji webata otu carboxymethyl. Ngwaahịa a na-esi na ya pụta bụ neutralized iji nweta ụdị nnu sodium nke carboxymethylcellulose.
Njirimara anụ ahụ na kemịkal:
Solubility: NaCMC bụ nke ukwuu soluble na mmiri, na-eme a doro anya na viscous ngwọta. Nke a solubility bụ isi njirimara maka ojiji ya zuru ebe niile na ụlọ ọrụ dị iche iche.
Viscosity: Enwere ike gbanwee viscosity nke sodium carboxymethylcellulose ngwọta site na ịchịkwa ogo nke nnọchi na itinye uche. Ngwongwo a na-eme ka ọ dị mma maka ngwa chọrọ thickening ma ọ bụ gelling.
Nkwụsi ike: NaCMC ka kwụsiri ike karịa oke pH, nke na-eme ka ike ya dị iche iche pụta.
Ịmepụta ihe nkiri: Ọ nwere ihe na-emepụta ihe nkiri na enwere ike iji ya mepụta ihe nkiri na mkpuchi na ngwa dị iche iche.

Thickers: Na-abawanye viscosity nke ncha ntutu, ntacha eze na ngwaahịa nlekọta onwe onye ndị ọzọ.
textile:
Onye na-ahụ maka nha nha: a na-eji maka nha akwa iji kwalite ike na ire ụtọ nke eriri n'oge usoro ịkwa akwa.
Tapawa mbipụta: Ọ na-arụ ọrụ dị ka thickener na rheology modifier na tapawa mbipụta akwa.
Ụlọ ọrụ mmanụ na gas:
Mmiri mmiri: NaCMC bụeji dị ka tackifier na-egwupụta mmiri mmiri iji welie ya rheological Njirimara.

Ọgwụgwọ mmiri: A na-eji ya na usoro ọgwụgwọ mmiri n'ihi njirimara flocculation ya.
Ihe nchacha: Ọ na-arụ ọrụ dị ka ihe nkwụsi ike n'ụdị ụfọdụ ncha.
Nchekwa na ụkpụrụ:
A na-amata sodium carboxymethylcellulose dị ka nchekwa (GRAS) maka iji nri na ngwa ọgwụ. Ọ na-akwado ụkpụrụ nhazi na nkọwapụta nke ọtụtụ ụlọ ọrụ setịpụrụ, gụnyere US Food and Drug Administration (FDA) na European Food Safety Authority (EFSA).
Sodium carboxymethyl cellulose bụ polymer multifunctional nwere ọtụtụ ngwa n'ime ụlọ ọrụ dị iche iche. Ngwakọta ya pụrụ iche nke solubility, njikwa viscosity, nkwụsi ike na ihe ndị na-emepụta ihe nkiri na-eme ka ọ bụrụ ihe bara uru n'ụdị dị iche iche. Ka ụlọ ọrụ ahụ na-aga n'ihu na-etolite, ọchịchọ nke sodium carboxymethylcellulose nwere ike ịga n'ihu n'ihi ntụgharị ya na ntinye aka na arụmọrụ ngwaahịa dị mma na ngwa dị iche iche.
