Kedu ihe bụ sodium Carboxymethyl cellulose?

Carboxymethylcellulose (CMC) bụ ngwakọta kemịkalụ kemịkalụ na nke a na-ejikarị eme ihe nke na-achọta ngwa na ụlọ ọrụ dị iche iche n'ihi ihe pụrụ iche ya. A na-enweta polymer a site na cellulose, polymer eke dị na mgbidi cell nke osisi. A na-emepụta Carboxymethylcellulose site na mgbanwe kemịkalụ nke cellulose site na iwebata otu carboxymethyl, nke na-eme ka mmiri sie ike na ike ịgbasa.

Ọdịdị Molecular na Synthesis

Carboxymethylcellulose nwere agbụ cellulose nwere otu carboxymethyl (-CH2-COOH) jikọtara na ụfọdụ otu hydroxyl na nkeji glucose. Njikọ nke CMC na-agụnye mmeghachi omume nke cellulose na chloroacetic acid, na-ebute ngbanwe nke atom hydrogen na cellulose chain na otu carboxymethyl. Ogo nke nnọchi (DS), nke na-egosi nkezi ọnụọgụ nke otu carboxymethyl otu glucose, na-emetụta njirimara nke CMC.

Njirimara anụ ahụ na kemịkalụ

1. Solubility: Otu n'ime ihe ndị a ma ama nke CMC bụ mmiri na-edozi ya, na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dị arọ na ngwọta mmiri. Ogo nke nnọchi na-emetụta solubility, na elu DS na-eduga na ụba mmiri solubility.
2. Viscosity: A na-eji Carboxymethylcellulose kpọrọ ihe maka ikike ya ịbawanye viscosity nke mmiri mmiri. Nke a na-eme ka ọ bụrụ ihe a na-ahụkarị na ngwaahịa dị iche iche, dị ka ihe oriri, ọgwụ na ngwaahịa nlekọta onwe onye.
3. Ihe nkiri na-emepụta ihe nkiri: CMC nwere ike ịmepụta ihe nkiri mgbe akọrọ, na-enye aka na ngwa ya na ụlọ ọrụ ebe a chọrọ mkpuchi dị nro, na-agbanwe agbanwe.
4. Ion Exchange: CMC nwere ihe mgbanwe ion, na-enye ya ohere ịmekọrịta ion na ngwọta. A na-erigbukarị ihe onwunwe a n'ụlọ ọrụ dị ka igwu mmanụ na ọgwụgwọ mmiri mkpofu.
5. Nkwụsi ike: CMC kwụsiri ike n'okpuru ọnọdụ pH dịgasị iche iche, na-agbakwunye na ike ya na ngwa dị iche iche.

1. Ụlọ ọrụ nri:

• Ihe na-eme ka ọ dị arọ: A na-eji CMC eme ihe dị ka ihe na-eme ka ọ sie ike na ngwaahịa nri dị iche iche, gụnyere sauces, uwe, na ngwaahịa mmiri ara ehi.
• Stabilizer: Ọ na-eme ka emulsions dị na ngwaahịa nri, na-egbochi nkewa.
• Texture Modifier: CMC na-akwalite udidi na ọnụ nke ụfọdụ ihe oriri.

2. Ngwa ọgwụ:

• Ihe nchikota: A na-eji CMC eme ihe dị ka ihe nkwụnye ọgwụ na mbadamba ọgwụ, na-enyere aka ijide ihe ndị ahụ ọnụ.
• Onye nnọchi anya nkwusioru: A na-eji ya n'ọrụ na ọgwụ mmiri mmiri iji gbochie idozi irighiri ihe.

3. Ngwaahịa nlekọta onwe onye:

• Viscosity Modifier: A na-agbakwunye CMC na ihe ịchọ mma, shampoos, na lotions iji mezie viscosity ha ma melite udidi ha.
• Stabilizer: Ọ na-eme ka emulsions guzosie ike na nhazi ihe ịchọ mma.

4. Ụlọ ọrụ akwụkwọ:

• Agent Sizing Surface: A na-eji CMC eme ihe na ụlọ ọrụ akwụkwọ iji meziwanye njirimara elu nke akwụkwọ, dị ka ire ụtọ na mbipụta.

5. Ụlọ ọrụ akwa:

• Agent Sizing: A na-etinye CMC na eriri iji meziwanye ihe eji akpa ákwà ma welie ike nke ákwà na-esi na ya pụta.

6. Ịgba mmanụ:

• Onye nnọchi anya njikwa mfu mmiri: CMC na-arụ ọrụ n'ọrụ na-egwupụta mmiri iji chịkwaa mfu mmiri, na-ebelata ihe ize ndụ nke enweghị ntụkwasị obi nke ọma.

7. Ọgwụgwọ mmiri mkpofu:

• Flocculant: CMC na-arụ ọrụ dị ka flocculant iji chịkọta ụmụ irighiri ihe dị mma, na-eme ka mwepụ ha dị na usoro ọgwụgwọ mmiri.

Ihe gbasara gburugburu ebe obibi

A na-ahụta Carboxymethylcellulose dị mma maka ojiji na ngwa dị iche iche. Dị ka ihe na-emepụta cellulose, ọ bụ ihe na-emebi emebi, na mmetụta gburugburu ebe obibi ya dị ntakịrị. Otú ọ dị, ọ dị mkpa ịtụle usoro gburugburu ebe obibi nke mmepụta na ojiji ya.
