Njirimara nke CMC

Carboxymethyl cellulose (CMC) bụ polymer soluble mmiri soluble nke ewepụtara na cellulose, nwere ọtụtụ àgwà pụrụ iche na-eme ka a na-eji ya eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche. Nke a bụ njirimara isi nke CMC:

1. Mmiri Solubility: CMC bụ nke ukwuu soluble na mmiri, akpụ doro anya, viscous ngwọta. Ihe onwunwe a na-enye ohere maka ntinye dị mfe n'ime usoro mmiri mmiri, na-eme ka ọ dị mma maka iji ya mee ihe n'ọtụtụ ngwa.
2. Ihe na-eme ka ọ dị arọ: CMC na-arụ ọrụ dị ka onye na-emepụta ihe dị irè, na-amụba viscosity nke ngwọta mmiri na nkwụsịtụ. Ọ na-enye udidi na ahụ na ngwaahịa, na-eme ka nkwụsi ike na arụmọrụ ha dịkwuo elu.
3. Pseudoplasticity: CMC na-egosipụta omume pseudoplastic, nke pụtara viscosity ya na-ebelata na ọnụ ọgụgụ shear na-abawanye. Ngwongwo a na-enye ohere maka mgbapụta dị mfe, ịgwakọta na ngwa nke ngwaahịa nwere CMC, ebe ọ na-enye ezigbo nkwụsi ike n'elu iguzo.
4. Ịmepụta ihe nkiri: CMC nwere ihe na-emepụta ihe nkiri, na-enye ya ohere ịmepụta ihe nkiri na-agbanwe agbanwe mgbe akpọnwụwo. Njirimara a na-eme ka ọ baa uru na ngwa ebe a na-achọ ihe nkiri nchebe ma ọ bụ ihe mgbochi, dị ka ihe mkpuchi, nrapado, na nkwakọ nri.
5. Ihe nchikota: CMC na-arụ ọrụ dị ka onye na-ekekọta na ngwa dị iche iche, na-eme ka nchikota nke irighiri ihe ma ọ bụ eriri na nhazi. Ọ na-eme ka ike na iguzosi ike n'ezi ihe nke ngwaahịa dịkwuo mma, na-eme ka arụmọrụ ha na ịdịte aka.
6. Stabilizer: CMC na-eje ozi dị ka stabilizer, na-egbochi idozi ma ọ bụ nkewa nke irighiri ihe na suspensions ma ọ bụ emulsions. Ọ na-enyere aka ịnọgide na-enwe otu na ịdị n'otu nke ngwaahịa, na-eme ka ịdị mma na-agbanwe agbanwe na oge.
7. Njide mmiri: CMC nwere ezigbo njide mmiri, na-enye ya ohere ijide mmiri ma gbochie mmiri mmiri n'ụdị. Ihe onwunwe a bara uru na ngwa ebe njikwa mmiri dị mkpa, dị ka ihe owuwu na ngwaahịa nlekọta onwe onye.
8. Njirimara Ionic: CMC nwere otu carboxyl nke nwere ike ionize na mmiri, na-enye ya ihe ndị anionic. Nke a na-enye ohere CMC ka ya na ụmụ irighiri ihe ndị ọzọ ebubo ma ọ bụ n'elu na-emekọrịta ihe, na-enye aka n'ike ya, nkwụsi ike, na ijikọ.
9. Nkwụsi ike pH: CMC kwụsiri ike karịa oke pH, site na acidic ruo ọnọdụ alkaline. Ọdịiche a na-enye ohere maka iji ya mee ihe na ọkwa pH dị iche iche na-enweghị mmebi ma ọ bụ mfu nke arụmọrụ.
10. Biodegradability: CMC sitere na isi mmalite cellulose eke ma bụrụ nke nwere ike imebi n'okpuru ọnọdụ gburugburu ebe obibi kwesịrị ekwesị. Ọ na-adaba n'ime ngwaahịa ndị na-adịghị emerụ ahụ, na-eme ka ọ bụrụ enyi na gburugburu ebe obibi ma na-adigide.

njirimara nke CMC na-eme ka ọ bụrụ ihe mgbakwunye bara uru n'ọtụtụ ụlọ ọrụ, gụnyere nri, ọgwụ, nlekọta onwe onye, ​​textiles, akwụkwọ, na ihe owuwu. Ntughari ya, mmiri solubility, ikike nke ukwuu, na ihe ndị na-emepụta ihe nkiri na-enye aka n'iji ya eme ihe na ngwa ngwa.
