Kedu ihe bụ chịngọm cellulose?

Cellulose chịngọm, makwaara dị ka carboxymethylcellulose (CMC), bụ a mmiri-soluble polima ewepụtara si cellulose, a eke polima nke na-etolite isi structural akụkụ nke osisi cell mgbidi. A na-eji chịngọm cellulose eme ihe n'ọtụtụ ebe n'ime nri, ọgwụ na ụlọ ọrụ nlekọta onwe onye dị ka ihe na-agbapụta, stabilizer, na ihe nkedo n'ihi ihe pụrụ iche ya.

A na-emepụta chịngọm cellulose site n'ịgbanwe cellulose na kemịkal site na mmeghachi omume na sodium hydroxide na monochloroacetic acid. Ngwaahịa a na-esi na ya pụta bụ nnu sodium nke carboxymethylcellulose, nke bụ mmiri na-edozi mmiri, polymer anionic nke nwere ike ịmepụta ihe dị ka gel mgbe hydrated.

Otu n'ime isi eji chịngọm cellulose eme ihe bụ ihe na-agbakọba na ngwaahịa nri. Enwere ike iji ya mee ihe n'ụdị ngwa nri dị iche iche, gụnyere sauces, mgbakwasa, ihe ndị esiri esi, na ice cream. N'ime ngwa ndị a, chịngọm cellulose na-arụ ọrụ dị ka ihe na-eme ka ọ sie ike site n'ịbawanye viscosity nke ngwaahịa ahụ, na-eme ka ọdịdị ahụ dịkwuo mma, na-egbochi nkewa nke ihe oriri. A na-ejikarị chịngọm cellulose na-ejikọta ya na ihe ndị ọzọ, dị ka xanthan chịngọm ma ọ bụ guar gum, iji nweta mmetụta ahụ.chọrọ udidi na nkwụsi ike.

A na-ejikwa chịngọm cellulose mee ihe dị ka ihe nkwụsi ike na ngwaahịa nri. Ọ nwere ike igbochi ịmepụta kristal ice na nri oyi kpọnwụrụ, gbochie nkewa nke ihe ndị dị na emulsions, ma gbochie nsị na ihe ọṅụṅụ. Tụkwasị na nke ahụ, a pụrụ iji chịngọm cellulose mee ihe dị ka ihe nkedo na ngwaahịa anụ, dị ka sausaji na anụ anụ, iji meziwanye ọdịdị ma belata abụba.

Na ụlọ ọrụ na-emepụta ọgwụ, a na-eji cellulose chịngọm mee ihe dị ka onye na-ekekọta ihe na mbadamba mbadamba iji jikọta ihe ndị na-arụ ọrụ ọnụ ma melite mkpakọ nke ntụ ntụ. A na-ejikwa chịngọm cellulose mee ihe dị ka ihe na-agbasa na mbadamba nkume na capsules iji nyere aka na nbibi nke mbadamba nkume ma ọ bụ capsule na usoro nri nri.

N'ime ụlọ ọrụ nlekọta onwe onye, ​​a na-eji cellulose chịngọm mee ihe dị ka ihe na-esikwu ike na nkwụsi ike na ngwaahịa dị iche iche, gụnyere shampoos, conditioners, na lotions. Enwere ike iji ya dị ka onye na-emepụta ihe nkiri na ntutu isi na ngwaahịa nhazi ndị ọzọ.

Otu n'ime uru nke cellulose chịngọm bụ na ọ naghị egbu egbu na nke na-adịghị ahụ efe, na-eme ka ọ dị mma maka iji ya mee ihe n'ọtụtụ ngwa. Tụkwasị na nke ahụ, chịngọm cellulose na-eguzosi ike n'elu pH dịgasị iche iche ma ọ dịghị emetụta okpomọkụ ma ọ bụ na-ekpo ọkụ, na-eme ka ọ dị mma maka iji mee ihe n'ụdị nhazi dị iche iche.

Cellulose chịngọm bụkwa ihe na-emetụta gburugburu ebe obibi. A na-enweta ya site na akụ nwere ike imegharị ya, usoro mmepụta ahụ na-arụkwa ọrụ ike. Cellulose chịngọm bụkwa ihe na-emebi emebi ma nwee ike imebi ya site na usoro okike na gburugburu ebe obibi.

N'agbanyeghị ọtụtụ uru ọ bara, enwere ụfọdụ njedebe na iji cellulose chịngọm. Otu n'ime njedebe ndị bụ isi bụ na ọ nwere ike isi ike ịgbasa na mmiri, nke nwere ike iduga nkwụsịtụ na arụmọrụ na-ekwekọghị ekwekọ. Tụkwasị na nke ahụ, chịngọm cellulose nwere ike inwe mmetụta na-adịghị mma na ekpomeekpo na ọnụ nke ụfọdụ ngwaahịa nri, karịsịa n'ọtụtụ dị elu.
