Sodium Carboxymethyl Cellulose (CMC)

Sodium carboxymethyl cellulose (CMC) bụ polymer soluble mmiri ewepụtara na cellulose, a eke onyinye dị na osisi cell mgbidi. A na-ejikarị ya eme ihe dị ka onye na-eto eto, stabilizer, na emulsifier n'ọtụtụ ụlọ ọrụ, gụnyere nri, ọgwụ, nlekọta onwe onye, ​​na textiles. N'isiokwu a, anyị ga-atụle njirimara, ngwa na uru nke CMC.

Njirimara nke CMC

CMC bụ ọcha ma ọ bụ na-acha ọcha, enweghị isi, na ntụ ntụ na-enweghị ụtọ nke na-agbaze nke ukwuu na mmiri. A na-enweta ya site na cellulose site na usoro mgbanwe kemịkalụ nke gụnyere mgbakwunye nke otu carboxymethyl na molekul cellulose. Ogo nke nnọchi (DS) na-ekpebi ọnụọgụ nke otu carboxymethyl otu glucose n'ime molekul cellulose, nke na-emetụta njirimara nke CMC.

CMC nwere ọtụtụ ihe na-eme ka ọ baa uru na ngwa dị iche iche. Ọ bụ nke ukwuu viscous ma nwee ezigbo ikike ijide mmiri, nke na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma na nkwụsi ike. Ọ bụkwa ezigbo emulsifier ma nwee ike ịmepụta nkwusioru kwụsiri ike na ngwọta mmiri. Ọzọkwa, CMC bụ pH-sensitive, na viscosity ya na-ebelata ka pH na-abawanye. Ngwongwo a na-enye ohere iji ya mee ihe n'ọtụtụ pH gburugburu.

Ngwa nke CMC

1. Ụlọ ọrụ nri

CMC bụ ihe eji eme ihe n'ọtụtụ ebe na ụlọ ọrụ nri, ebe a na-eji ya dị ka thickener, stabilizer, na emulsifier na ngwaahịa dị iche iche. A na-ejikarị ya eme ihe n'ụdị eghe, ngwaahịa mmiri ara ehi, nri nri, uwe, na ihe ọṅụṅụ. N'ime ngwa ndị a esiri esi, CMC na-enyere aka melite udidi, nhazi crumb, na ndụ nchekwa nke ngwaahịa ikpeazụ. N'ime ngwaahịa mmiri ara ehi, CMC na-egbochi ịmepụta kristal ice ma na-eme ka ọdịdị ọnụ na ọnụ nke ice cream na desserts ndị ọzọ oyi kpọnwụrụ. Na sauces na ejiji, CMC na-enyere aka igbochi nkewa ma nọgide na-enwe nguzozi na ọdịdị a chọrọ.

2. Ụlọ ọrụ ọgwụ

A na-ejikwa CMC na ụlọ ọrụ na-emepụta ọgwụ, ebe a na-eji ya dị ka ihe nkedo, disintegrant, na thickener na mbadamba nkume na capsule. A na-ejikwa ya mee ihe n'ụdị ihe dị ka ude na gels dị ka ihe na-agbapụta na emulsifier. CMC bụ ihe na-emekọrịta ihe na biodegradable, na-eme ka ọ bụrụ nhọrọ dị mma ma dị irè maka ngwa ọgwụ.

3. Ụlọ ọrụ nlekọta onwe onye

A na-eji CMC na ụlọ ọrụ nlekọta onwe onye dị ka onye na-agba ume, stabilizer, na emulsifier n'ọtụtụ ngwaahịa, gụnyere shampoos, conditioners, lotions, na creams. Na ngwaahịa nlekọta ntutu isi, CMC na-enyere aka imeziwanye ọdịdị na ọdịdị nke ntutu isi, ebe na ngwaahịa nlekọta anụ ahụ, ọ na-enyere aka melite mgbasa na absorption nke ihe ndị na-arụ ọrụ.

4. Ụlọ ọrụ textile

A na-eji CMC eme ihe na ụlọ ọrụ textile dị ka onye na-emepụta ihe, nke na-enyere aka melite ike na nkwụsi ike nke yarn n'oge ịkwa ákwà. A na-ejikwa ya dị ka ihe na-esi ísì ụtọ na-ebi akwụkwọ mado yana dị ka ihe nkedo na ịcha akwa na imecha usoro.

Uru nke CMC

1. Ederede na ọdịdị emelitere

CMC bụ ihe dị iche iche nke nwere ike inye aka mee ka ọdịdị dị iche iche, nkwụsi ike, na ọdịdị dị iche iche nke ngwaahịa. Enwere ike iji ya mee ihe dị ka onye na-agba agba, stabilizer, na emulsifier, nke na-enyere aka melite ogo zuru oke na mkpesa nke ngwaahịa ikpeazụ.

2. Ndụ shelf emelitere

CMC nwere ike inye aka melite ndụ nchekwa nke nri na ngwaahịa ọgwụ site na igbochi nkewa nke ihe oriri na ịmepụta kristal ice. Ihe onwunwe a na-enyere aka ịnọgide na-adị mma na ịdị ọhụrụ nke ngwaahịa ahụ ruo ogologo oge.

3. Ọnụ-dị irè

CMC bụ ihe ọzọ dị ọnụ ala karịa ndị ọzọ thickeners na stabilizers eji na dị iche iche ngwa. A na-enweta ya n'ọtụtụ ebe ma nwee ọnụ ala dị ala ma e jiri ya tụnyere ihe ndị ọzọ na-emepụta sịntetik na stabilizers, na-eme ka ọ bụrụ nhọrọ mara mma maka ọtụtụ ụlọ ọrụ.
