Carboxymethylcellulose (CMC) na cellulose bụ ma polysaccharides nwere ihe dị iche iche na ngwa. Ịghọta ndịiche ha na-achọ inyocha usoro ha, ihe onwunwe ha, mmalite ha, ụzọ mmepụta ha na ngwa ha.
Cellulose:
1. Nkọwa na nhazi:
Cellulose bụ polysaccharide sitere n'okike nke nwere ụdọ linear nke nkeji β-D-glucose jikọtara ya na njikọ β-1,4-glycosidic.
Ọ bụ isi ihe nhazi nke mgbidi cell osisi, na-enye ike na isi ike.
2. Isi mmalite:
Cellulose dị ukwuu n'okike ma na-esite na isi ihe ọkụkụ dị ka osisi, owu na ihe ndị ọzọ na-emepụta ihe.
3. Mmepụta:
Mmepụta nke cellulose na-agụnye ịwepụta cellulose n'ime osisi wee hazie ya site na ụzọ ndị dị ka nsị kemịkal ma ọ bụ igwe igwe iji nweta eriri.
4. Arụmọrụ:
N'ụdị okike ya, cellulose adịghị edozi na mmiri na ọtụtụ ihe mgbaze organic.
Ọ nwere ike dị elu, na-eme ka ọ dị mma maka ngwa ebe ike na ịdịte aka dị oke mkpa.
Cellulose bụ ihe na-emebi emebi na gburugburu ebe obibi.
5. Ngwa:
Cellulose nwere ngwa dị iche iche, gụnyere mmepụta akwụkwọ na bọọdụ, textiles, plastik dabeere na cellulose, yana dịka mgbakwunye eriri nri.
Carboxymethylcellulose (CMC):
1. Nkọwa na nhazi:
Carboxymethylcellulose (CMC) bụ ihe sitere na cellulose nke a na-ewebata otu carboxymethyl (-CH2-COOH) n'ime ọkpụkpụ cellulose.
2. Mmepụta:
A na-emepụtakarị CMC site n'ịgwọ cellulose na chloroacetic acid na alkali, na-ebute nnọchi nke otu hydroxyl na cellulose na otu carboxymethyl.
3. Solubility:
N'adịghị ka cellulose, CMC bụ mmiri-soluble na-emepụta ihe ngwọta colloidal ma ọ bụ gel dabere na ntinye uche.
4. Arụmọrụ:
CMC nwere ma hydrophilic na hydrophobic Njirimara, na-eme ka ọ dị mma maka ngwa dị iche iche na nri, ọgwụ na ụlọ ọrụ mmepụta ihe.
Ọ nwere ikike imepụta ihe nkiri na enwere ike iji ya dị ka thickener ma ọ bụ stabilizer.
5. Ngwa:
A na-eji CMC eme ihe na ụlọ ọrụ nri dị ka ihe na-agbapụta, stabilizer na emulsifier na ngwaahịa ndị dị ka ice cream na akwa salad.
N'ime ọgwụ, a na-eji CMC mee ihe dị ka ihe nchikota n'ụdị mbadamba.
A na-eji ya na nhazi nha na imecha nke ụlọ ọrụ textile.
iche:
1. Solubility:
Cellulose na-esighi ike na mmiri, ebe CMC na-agbaze na mmiri. Ọdịiche a dị na solubility na-eme ka CMC dị iche iche na ngwa ngwa dị iche iche, karịsịa na ụlọ ọrụ ebe a na-ahọrọ nhazi mmiri.
2. Usoro mmepụta:
Mmepụta nke cellulose gụnyere mmịpụta na nhazi site na osisi, ebe CMC na-arụ ọrụ site na usoro mgbanwe kemịkalụ gụnyere cellulose na carboxymethylation.
3. Nhazi:
Cellulose nwere usoro ahịrị na enweghị alaka, ebe CMC nwere otu carboxymethyl jikọtara ya na ọkpụkpụ azụ cellulose, na-enye usoro gbanwetụrụ na nkwalite solubility.
4. Ngwa:
A na-ejikarị cellulose eme ihe na ụlọ ọrụ dịka akwụkwọ na textiles ebe ike ya na adịghị ike ya na-enye uru.
N'aka nke ọzọ, a na-eji CMC eme ihe n'ọtụtụ dịgasị iche iche nke ụlọ ọrụ, gụnyere nri, ọgwụ na ihe ịchọ mma, n'ihi na mmiri na-edozi ya na ntụgharị ya.
5. Njirimara anụ ahụ:
A maara cellulose maka ike ya na isi ike ya, na-enye aka na nhazi nke osisi.
CMC na-eketa ụfọdụ ihe onwunwe nke cellulose ma nweekwa ndị ọzọ, dị ka ike ịmepụta gels na ngwọta, na-enye ya ọtụtụ ngwa ngwa.
Ọ bụ ezie na cellulose na carboxymethyl cellulose nwere ihe jikọrọ ọnụ, usoro ha dị iche iche na ihe onwunwe ha emeela ka ngwa dị iche iche dị na ụlọ ọrụ dị iche iche. Ike Cellulose na insolubility nwere ike ịba uru n'ọnọdụ ụfọdụ, ebe mmiri mmiri nke CMC na nhazi a gbanwere na-eme ka ọ bụrụ ihe bara uru n'ọtụtụ ngwaahịa na usoro.
