Ihe na-emetụta Sodium carboxymethylcellulose viscosity

Enwere ike imetụta viscosity nke sodium carboxymethylcellulose (CMC) ngwọta site n'ọtụtụ ihe. Nke a bụ ụfọdụ isi ihe na-emetụta viscosity nke ngwọta CMC:

1. Ntụkwasị: Viscosity nke CMC ngwọta n'ozuzu na-abawanye na ụba itinye uche. Ọnụ ọgụgụ dị elu nke CMC na-ebute ọtụtụ agbụ polymer na ngwọta, na-eduga n'inweta njikọ dị ukwuu na viscosity dị elu. Otú ọ dị, a na-enwekarị njedebe na mmụba viscosity na ọkwa dị elu n'ihi ihe ndị dị ka reology ngwọta na polymer-solvent mmekọrịta.
2. Degree of nnọchi (DS): Ogo nke nnọchi na-ezo aka na nkezi ọnụ ọgụgụ nke carboxymethyl otu glucose n'ime agbụ cellulose. CMC nwere DS dị elu na-achọ inwe viscosity dị elu n'ihi na ọ nwere otu ebubo ebubo karịa, nke na-akwalite mmekọrịta intermolecular siri ike yana iguzogide oke.
3. Ibu Molecular: Arọ molikula nke CMC nwere ike imetụta viscosity ya. Arọ molekụla dị elu CMC na-eduga na ngwọta viscosity dị elu n'ihi ịba ụba nke yinye na ụdọ polymer dị ogologo. Agbanyeghị, ịdị arọ molekụla dị elu nke ukwuu CMC nwekwara ike ịkpata viscosity ngwọta na-abawanye na-enweghị mmụba nha anya na nrụpụta nrụpụta.
4. Okpomọkụ: Okpomọkụ nwere mmetụta dị ukwuu na viscosity nke ngwọta CMC. N'ozuzu, viscosity na-ebelata ka okpomọkụ na-abawanye n'ihi mbelata mmekọrịta polymer-ihe mgbaze yana ụbara molikula. Otú ọ dị, mmetụta nke okpomọkụ na viscosity nwere ike ịdịgasị iche dabere na ihe ndị dị ka nchịkọta polymer, arọ molecular, na ngwọta pH.
5. pH: The pH nke CMC ngwọta nwere ike imetụta ya viscosity n'ihi mgbanwe na polymer ionization na conformation. CMC na-adịkarị viscous na ụkpụrụ pH dị elu n'ihi na otu carboxymethyl bụ ionized, na-eduga n'ọgụ electrostatic siri ike n'etiti ụdọ polymer. Agbanyeghị, ọnọdụ pH dị oke egwu nwere ike ibute mgbanwe na solubility polymer na conformation, nke nwere ike imetụta viscosity dị iche iche dabere na ọkwa CMC akọwapụtara na nhazi.
6. Ọdịnaya Nnu: Ọnụnọ nke nnu na ngwọta nwere ike imetụta viscosity nke ngwọta CMC site na mmetụta na mmekọrịta polymer-solvent na mmekọrịta ion-polymer. N'ọnọdụ ụfọdụ, mgbakwunye nke nnu nwere ike ịbawanye viscosity site na nyochaa mmejọ electrostatic n'etiti ụdọ polymer, ebe n'ọnọdụ ndị ọzọ, ọ nwere ike ibelata viscosity site na imebi mmekọrịta polymer-ihe mgbaze na ịkwalite nchịkọta polymer.
7. Ọnụ ego Shear: Viscosity nke ngwọta CMC nwekwara ike ịdabere na ọnụ ọgụgụ shear ma ọ bụ ọnụego nke nrụgide na-etinye na ngwọta. Ngwọta CMC na-egosipụtakarị omume ịhịa aka n'ahụ, ebe viscosity na-ebelata site na ọnụ ọgụgụ shear na-abawanye n'ihi nhazi na nhazi nke ụdọ polymer n'akụkụ ụzọ mgbaba. Ogo nke ncha ntutu nwere ike ịdịgasị iche dabere n'ihe ndị dị ka mkpokọta polymer, ịdị arọ molekul, na pH ngwọta.

viscosity nke sodium carboxymethylcellulose ngwọta na-emetụta nchikota nke ihe gụnyere itinye uche, ogo nke nnọchi, ịdị arọ molecular, okpomọkụ, pH, ọdịnaya nnu, na ọnụ ọgụgụ shear. Ịghọta ihe ndị a dị mkpa maka ịkwalite viscosity nke ngwọta CMC maka ngwa dị iche iche na ụlọ ọrụ dịka nri, ọgwụ, ihe ịchọ mma, na nlekọta onwe onye.
