Ihe na-emetụta na carboxymethylcellulose sodium nnu Ngwọta Àgwà

Carboxymethylcellulose sodium salt (CMC-Na) bụ polymer soluble mmiri nke a na-ejikarị na ngwa ụlọ ọrụ dị iche iche na nke azụmahịa, gụnyere nri, ọgwụ na ngwaahịa nlekọta onwe onye. Omume nke CMC-Na ngwọta na-emetụta ọtụtụ ihe, ụfọdụ n'ime ha na-atụle n'okpuru:

1. Arọ molecular: arọ molekụla nke CMC-Na na-emetụta omume ngwọta ya, viscosity, na njirimara rheological. Ndị arọ molekụla dị elu CMC-Na polymers na-enwekarị viscosities ngwọta dị elu ma na-egosipụta omume na-akpachapụ anya ka ukwuu karịa ndị mmekọ ibu molekụla dị ala.
2. Ntụkwasị obi: Ntinye uche nke CMC-Na na ngwọta na-emetụtakwa omume ya. N'ebe dị ala, ihe ngwọta CMC-Na na-akpa àgwà dị ka mmiri mmiri Newtonian, ebe ọ bụ na ọkwa dị elu, ha na-aghọwanye viscoelastic.
3. Ike Ionic: Ike ionic nke ngwọta nwere ike imetụta omume nke ngwọta CMC-Na. Ọnụnọ nnu dị elu nwere ike ime ka CMC-Na gbakọta, na-eduga n'ịbawanye viscosity na mbelata solubility.
4. pH: pH nke ngwọta nwekwara ike imetụta omume nke CMC-Na. Na ụkpụrụ pH dị ala, CMC-Na nwere ike ịghọ protonated, na-eduga na mbelata solubility na ụba viscosity.
5. Okpomọkụ: Ọnọdụ okpomọkụ nke ngwọta nwere ike imetụta omume nke CMC-Na site n'ịgbanwe ya solubility, viscosity, na gelation omume. Okpomọkụ dị elu nwere ike ịbawanye solubility nke CMC-Na, ebe okpomọkụ dị ala nwere ike ime ka gelation.
6. Ọnụ ọgụgụ nke shear: Ọnụ ọgụgụ ma ọ bụ ọnụ ọgụgụ nke ngwọta nke ngwọta nwere ike imetụta omume nke CMC-Na site n'ịgbanwe viscosity ya na njirimara rheological. N'ọ̀tụ̀tụ̀ dị elu nke shear, ngwọta CMC-Na na-aghọ obere viscous ma na-akpachapụ anya karị.

N'ozuzu, omume nke CMC-Na ngwọta na-emetụta ọtụtụ ihe, gụnyere ịdị arọ molecular, ntinye uche, ike ionic, pH, okpomọkụ, na ọnụ ọgụgụ shear. Ịghọta ihe ndị a dị mkpa n'ịmepụta na imezi usoro dabere na CMC-Na maka ngwa dị iche iche.
