Njirimara sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (CMC) bụ polymer soluble mmiri soluble ewepụtara na cellulose, na o nwere ọtụtụ ihe dị mkpa Njirimara na-eme ka ọ bara uru na dị iche iche ulo oru ngwa. Nke a bụ ụfọdụ isi njirimara sodium carboxymethyl cellulose:

1. Mmiri Solubility: CMC bụ nke ukwuu soluble na mmiri, na-eme doro anya na viscous ngwọta. Ngwongwo a na-enye ohere maka ntinye dị mfe n'ime sistemu mmiri dị ka ngwọta, nkwusioru na emulsions.
2. Viscosity: CMC na-egosipụta ihe ndị na-eme ka ọ dị mma, na-enye aka na ike ya iji mee ka viscosity nke usoro mmiri mmiri dịkwuo elu. Enwere ike idozi viscosity nke ngwọta CMC site na ihe dị iche iche dị ka itinye uche, ịdị arọ molecular, na ogo nke nnọchi.
3. Ịme ihe nkiri: CMC nwere ihe na-emepụta fim, na-enye ya ohere ịmepụta ihe nkiri dị gịrịgịrị, na-agbanwe agbanwe na otu mgbe akpọnwụwo. Ihe nkiri ndị a na-enye ihe mgbochi, nkwụsịtụ, na nchebe, na-eme ka CMC dị mma maka ngwa dị ka mkpuchi, ihe nkiri, na adhesives.
4. Hydration: CMC nwere oke hydration, nke pụtara na ọ nwere ike ịmịnye ma na-ejigide nnukwu mmiri. Ihe onwunwe a na-eme ka ọ dị irè dị ka ihe na-eme ka ọ dị arọ, yana ike ya na-eme ka njigide mmiri dị n'ụdị dị iche iche.
5. Pseudoplasticity: CMC na-egosipụta omume pseudoplastic, nke pụtara viscosity ya na-ebelata n'okpuru nrụgide shear wee laghachi na viscosity mbụ ya mgbe ewepụrụ nrụgide ahụ. Ngwongwo a na-enye ohere ngwa ngwa na nhazi nhazi dị ka agba, ink na ihe ịchọ mma.
6. Nkwụsi ike pH: CMC kwụsiri ike karịa oke pH, site na acidic ruo ọnọdụ alkaline. Ọ na-ejigide arụmọrụ ya na arụmọrụ ya na nhazi ọkwa pH dị iche iche, na-enye ngwa ngwa n'ofe ụlọ ọrụ dị iche iche.
7. Ntagide Nnu: CMC na-egosipụta ezigbo nnabata nnu, na-eme ka ọ dị mma maka iji usoro nwere electrolytes ma ọ bụ nnukwu nnu. Ngwongwo a dị mkpa karịsịa n'ime ngwa ndị dị ka igwu mmiri mmiri, ebe ọdịnaya nnu nwere ike ịdị mkpa.
8. Thermal Stability: CMC na-egosi ezigbo nkwụsi ike nke okpomọkụ, na-eguzogide okpomọkụ na-agafeghị oke na-ezute na usoro mmepụta ihe. Agbanyeghị, ikpughe ogologo oge na oke okpomọkụ nwere ike ibute mbibi.
9. Ndakọrịta: CMC dakọtara na ọtụtụ ihe ndị ọzọ, ihe mgbakwunye, na ihe ndị a na-ejikarị eme ihe n'ụdị mmepụta ihe. Enwere ike itinye ya ngwa ngwa n'ime usoro iji nweta njirimara rheological na arụmọrụ achọrọ.

sodium carboxymethyl cellulose nwere ngwakọta pụrụ iche nke akụrụngwa, gụnyere mmiri solubility, njikwa viscosity, ikike imepụta ihe nkiri, hydration, pseudoplasticity, nkwụsi ike pH, nnabata nnu, nkwụsi ike ọkụ, na ndakọrịta. Ngwongwo ndị a na-eme ka CMC bụrụ ihe mgbakwunye bara uru na ọtụtụ ngwa ụlọ ọrụ, gụnyere nri, ọgwụ, ngwaahịa nlekọta onwe onye, ​​textiles, paints, adhesives, and waters.
