Njirimara nke CMC

Sodium carboxymethyl cellulose (CMC) bụ polymer soluble mmiri ewepụtara na cellulose, a eke polima dị na osisi cell mgbidi. Nke a bụ ụfọdụ isi njirimara CMC:

1. Mmiri solubility: CMC bụ nke ukwuu soluble na mmiri na ndị ọzọ aqueous ngwọta, akpụ doro anya ma ọ bụ ubé turbid ngwọta.
2. Viscosity: CMC nwere ike ịmepụta ngwọta viscous dị ukwuu, dabere na ogo nke nnọchi, ịdị arọ molecular, na itinye uche. A na-ejikarị ya eme ihe dị ka thickener na rheology modifier na ngwa dị iche iche.
3. Nkwụsi ike pH: CMC kwụsiri ike n'elu ọnụ ọgụgụ pH dịgasị iche iche, nke sitere na pH 2 ruo 12. Ọ nwere ike ịnọgide na-enwe ike na-eme ka ọ sie ike na ọnọdụ acidic, na-anọpụ iche, na alkaline.
4. Mmetụta ike ionic: CMC nwere ike imetụta ike ionic nke ngwọta. Ọ nwere ike ịmepụta gels ndị na-esighị ike ma ọ bụ tụfuo ihe ndị na-eme ka ọ dị arọ na ọnọdụ nnu dị elu.
5. Hygroscopicity: CMC bụ hygroscopic, nke pụtara na ọ nwere ike ịmịkọrọ mmiri sitere na gburugburu ebe obibi. Ngwongwo a nwere ike imetụta njikwa ya, nchekwa ya na arụmọrụ ya na ngwa ụfọdụ.
6. Ihe na-emepụta ihe nkiri: CMC nwere ike ịmepụta ihe nkiri na-agbanwe agbanwe na nke doro anya mgbe ọ kpọrọ nkụ. Enwere ike iji ya dị ka ihe mkpuchi ma ọ bụ ihe eji eme ihe na ngwa dị iche iche.
7. Biodegradability: CMC bụ biodegradable na gburugburu ebe obibi enyi. Enwere ike imebi ya site na enzymes nke microorganisms na-emepụta na ala ma ọ bụ mmiri.

N'ozuzu, sodium carboxymethyl cellulose bụ a vasatail polymer nwere ọtụtụ ihe onwunwe na-eme ka ọ bara uru na ngwa dị iche iche, dị ka nri, ọgwụ, nlekọta onwe onye, ​​na ụlọ ọrụ mmepụta ihe.
