Ọdịdị na ọrụ nke Sodium Carboxymethyl Cellulose

 

Sodium carboxymethyl cellulose (CMC) bụ polymer soluble mmiri soluble nke sitere na cellulose, a eke polysaccharide dị na osisi mgbidi cell. A na-eji CMC eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere nri na ihe ọṅụṅụ, ọgwụ ọgwụ, nlekọta onwe onye, ​​textiles, akwụkwọ, na mkpọ mmanụ, n'ihi nhazi ya pụrụ iche na arụ ọrụ ya. Ka anyị leba anya na nhazi na ọrụ nke sodium carboxymethyl cellulose:

1. Ọdịdị nke sodium Carboxymethyl Cellulose:

  • Ọkpụkpụ azụ Cellulose: Ọkpụkpụ azụ nke CMC nwere nkeji glucose ugboro ugboro jikọtara ya na β(1→4) njikọ glycosidic. Yinye polysaccharide linear a na-enye usoro nhazi na nkwụsi ike nke CMC.
  • Otu Carboxymethyl: A na-ewebata otu Carboxymethyl (-CH2-COOH) n'ime ọkpụkpụ azụ cellulose site na mmeghachi omume etherification. Ndị otu hydrophilic ndị a na-ejikọta na mmiri hydroxyl (-OH) nke nkeji glucose, na-enye mmiri solubility na ihe arụ ọrụ na CMC.
  • Ụkpụrụ ngbanwe: Ogo nke nnọchi (DS) na-ezo aka na nkezi ọnụ ọgụgụ nke carboxymethyl otu glucose n'ime agbụ cellulose. Ụkpụrụ DS dị elu na-egosi ogo dị ukwuu nke ngbanwe yana ụbara mmiri solubility nke CMC.
  • Arọ Molecular: Mkpụrụ ndụ CMC nwere ike ịdịgasị iche na ịdị arọ molekụla dabere na ihe ndị dị ka isi iyi nke cellulose, usoro njikọ, na ọnọdụ mmeghachi omume. A na-eji ihe e ji mara arọ molekụla site na paramita dị ka ọnụọgụ-nkezi molecular arọ (Mn), arọ-nkezi arọ molekụla (Mw), na viscosity-nkezi molecular arọ (Mv).

2. Ọrụ nke Sodium Carboxymethyl Cellulose:

  • Ọkpụkpụ: CMC na-arụ ọrụ dị ka onye na-ebu ibu na ngwọta mmiri na nkwusioru site na ịba ụba viscosity na imeziwanye udidi na mmetụta ọnụ. Ọ na-enye ngwaahịa dị iche iche anụ ahụ yana nkwekọ, gụnyere sauces, akwa akwa, ngwaahịa mmiri ara ehi, na usoro nlekọta onwe onye.
  • Nkwụsi ike: CMC na-eme ka emulsions, nkwusioru, na sistemụ colloidal guzosie ike site na igbochi nkewa nke oge, nhazi, ma ọ bụ ude. Ọ na-akwalite nkwụsi ike na ndụ nchekwa nke nri, ọgwụ na ngwaahịa ịchọ mma site n'ịkwado ihe ndị e ji achụsa otu.
  • Njide mmiri: CMC nwere ikike ịmịnye na idowe mmiri, na-eme ka ọ baa uru maka idebe mmiri na hydration na nri, ọgwụ na usoro nlekọta onwe onye. Ọ na-enyere aka igbochi nkụ, melite udidi ngwaahịa, na ogologo ndụ nchekwa.
  • Ịmepụta ihe nkiri: CMC na-emepụta ihe nkiri na-egbuke egbuke ma na-agbanwe agbanwe mgbe a mịrị amị, na-eme ka ọ dị mma maka ngwa ndị dị ka mkpuchi oriri, mkpuchi mbadamba, na ihe nkiri nchebe na ọgwụ na ihe ịchọ mma. Ihe nkiri ndị a na-enye ihe mgbochi megide mmiri, ikuku oxygen na gas ndị ọzọ.
  • Njide: CMC na-arụ ọrụ dị ka ihe nkedo na mbadamba mbadamba site n'ịkwalite adhesion n'etiti irighiri ihe na ikwado mkpakọ mbadamba. Ọ na-eme ka ike arụ ọrụ, ike siri ike, na nkesa nke mbadamba nkume dịkwuo mma, na-eme ka nnyefe ọgwụ dịkwuo mma na nnabata onye ọrịa.
  • Nkwụsịtụ na emulsifying: CMC na-akwụsị irighiri ihe siri ike ma na-eme ka emulsions dị na nri, ọgwụ na ngwaahịa nlekọta onwe onye. Ọ na-egbochi idozi ma ọ bụ nkewa nke ihe oriri ma hụ na nkesa otu na ọdịdị nke ngwaahịa ikpeazụ.
  • Gelling: N'okpuru ọnọdụ ụfọdụ, CMC nwere ike ịmepụta gels ma ọ bụ ihe dị ka gel, nke a na-eji na ngwa dị ka confectionery, dessert gels, na ngwaahịa nlekọta ọnya. Njirimara gelation nke CMC dabere na ihe ndị dị ka itinye uche, pH, okpomọkụ, na ọnụnọ nke ihe ndị ọzọ.

Na nchịkọta, sodium carboxymethyl cellulose (CMC) bụ a multifunctional polymer nwere a pụrụ iche Ọdịdị na a dịgasị iche iche nke ngwa na dị iche iche ọrụ. Ikike ya ịgbatị, kwụsie ike, idowe mmiri, imepụta ihe nkiri, kechie, kwụsịtụ, emulsify, na gel na-eme ka ọ bụrụ ihe mgbakwunye bara uru na nri na ihe ọṅụṅụ, ọgwụ, nlekọta onwe onye, ​​textiles, akwụkwọ, na mkpọ mmanụ. Ịghọta mmekọrịta dị n'usoro-ọrụ nke CMC dị mkpa maka ịkwalite arụmọrụ ya na nrụpụta ya na nhazi na ngwaahịa dị iche iche.
