Kedu ihe dị iche n'etiti sodium CMC na CMC?

Sodium carboxymethylcellulose (NaCMC) na carboxymethylcellulose (CMC) bụ ma mwepụta nke cellulose, a eke polima dị na osisi cell mgbidi. Ogige ndị a nwere ngwa na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, textiles na ndị ọzọ.

Sodium Carboxymethylcellulose (NaCMC):

1.Chemical Ọdịdị:

A na-ewepụta NaCMC na cellulose site na usoro mgbanwe kemịkalụ. A na-ewebata otu Carboxymethyl (-CH2-COOH) n'ime usoro cellulose, na ion sodium na-ejikọta ya na otu ndị a.
Nnu sodium nke CMC na-enye mmiri solubility na polymer.

2. Solubility:

NaCMC bụ mmiri-soluble ma mepụta ngwọta viscous. Ọnụnọ nke ion sodium na-eme ka ọ dị nro na mmiri ma e jiri ya tụnyere cellulose na-adịghị agbanwe agbanwe.

3. Atụmatụ na ọrụ:

Na-arụ ọrụ dị ka onye na-agbapụta, stabilizer na onye na-ejigide mmiri na ngwa dị iche iche.
Na-egosiputa omume pseudoplastic ma ọ bụ nke na-akpachapụ anya, nke pụtara na viscosity ya na-ebelata n'okpuru nrụgide siri ike.

4. Ngwa:

Ụlọ ọrụ nri: A na-eji ya dị ka ihe na-eme ka ọ sie ike na ngwaahịa nri dị ka sauces, ice cream na ngwaahịa esi nri.

Ọgwụ: Ejina usoro maka njide ya na ihe na-eme ka viscosity dịkwuo mma.

Ngwupu mmanụ: ejiri chịkwaa viscosity na mfu mmiri na mmiri na-egwupụta ihe.

5. Mmepụta:

Ejikọtara ya site na mmeghachi omume nke cellulose na sodium hydroxide na monochloroacetic acid.

Carboxymethylcellulose (CMC):

1.Chemical Ọdịdị:

CMC n'ụzọ sara mbara na-ezo aka n'ụdị cellulose carboxymethylated. O nwere ike ịbụ ma ọ bụ na ọ gaghị adịmetụtara ion sodium.

A na-ewebata otu Carboxymethyl n'ime ọkpụkpụ azụ cellulose.

2. Solubility:

CMC nwere ike ịdị n'ụdị dị iche iche, gụnyere nnu sodium (NaCMC) na nnu ndị ọzọ dị ka calcium CMC (CaCMC).

CMC sodium bụ ụdị mmiri a na-ejikarị eme ihe, ma dabere na ngwa ahụ, CMC nwekwara ike gbanwee ka ọ ghara ịdị na-agbaze na mmiri.

3. Atụmatụ na functions:

Yiri NaCMC, CMA na-eji C kpọrọ ihe maka ịgbatị ya, nkwụsi ike, yana ihe na-ejigide mmiri.

Nhọrọ nke CMC type (sodium, calcium, wdg) dabere na ihe achọrọ nke ngwaahịa ikpeazụ.

4. Ngwa:

A na-eji ya na ụlọ ọrụ nri, ọgwụ, textile, ceramics na mmepụta akwụkwọ.

Ụdị dị iche ichesnke CMC nwere ike họrọ dabere na kpọmkwem chọrọ nke ngwa.

5. Mmepụta:

Carboxymethylation nke cellulose nwere ike ịgụnye ọnọdụ mmeghachi omume dị iche iche na reagents, na-eduga n'ichepụta ụdị CMC dị iche iche.

Isi ihe dị iche n'etiti sodium CMC na CMC bụ ọnụnọ sodium ion. Sodium CMC na-ezo aka kpọmkwem na nnu sodium nke carboxymethyl cellulose, nke na-agbaze mmiri nke ukwuu. N'aka nke ọzọ, CMC bụ okwu sara mbara nke na-ekpuchi ụdị cellulose carboxymethylated dị iche iche, gụnyere sodium na nnu ndị ọzọ, nke ọ bụla nwere ihe onwunwe na ngwa nke ya. Nhọrọ n'etiti sodium CMC na CMC dabere na ebumnuche ebumnuche yana njirimara achọrọ nke ngwaahịa njedebe.
