Kufurira Zvinhu paSodium carboxymethylcellulose Viscosity

Iyo viscosity ye sodium carboxymethylcellulose (CMC) mhinduro inogona kupesvedzerwa nezvakawanda zvinhu.Heano zvimwe zvezvinhu zvakakosha zvinokanganisa viscosity yeCMC mhinduro:

1. Concentration: Iyo viscosity yeCMC mhinduro inowanzo wedzera nekuwedzera kuisa pfungwa.Kukwirira kwepamusoro kweCMC kunokonzeresa kuwanda kwepolymer cheni mumhinduro, zvichitungamira kune yakakura mamorekuru entanglement uye yakakwirira viscosity.Nekudaro, pane kazhinji muganho kune iyo viscosity kuwedzera pane yakakwira concentration nekuda kwezvinhu zvakaita semhinduro rheology uye polymer-solvent kupindirana.
2. Dhigirii reKutsiva (DS): Iyo dhigirii yekutsiva inoreva avhareji nhamba yemapoka ecarboxymethyl pachikamu cheglucose mucheni ye cellulose.CMC ine DS yepamusoro inoita kunge iine viscosity yepamusoro nekuti ine mapoka akawanda anochajiswa, ayo anosimudzira kusimba kweintermolecular kudyidzana uye kuramba kukuru kuyerera.
3. Molecular Weight: Iyo molecular huremu hweCMC inogona kukanganisa viscosity yayo.Yepamusoro mamorekuru uremu CMC kazhinji inotungamira kune yakakwirira viscosity mhinduro nekuda kwekuwedzera ketani kusungirirwa uye refu polymer cheni.Nekudaro, yakawandisa yakakwira mamorekuru uremu CMC inogona zvakare kukonzera yakawedzera mhinduro viscosity pasina kuwedzera kwakaenzana mukukora.
4. Tembiricha: Tembiricha ine yakakosha kukanganisa kune viscosity yeCMC mhinduro.Kazhinji, viscosity inodzikira sezvo tembiricha inowedzera nekuda kwekuderedzwa kwepolymer-solvent kupindirana uye kuwedzera kwema molecular kufamba.Nekudaro, mhedzisiro yetembiricha pane viscosity inogona kusiyana zvichienderana nezvinhu zvakaita se polymer concentration, molecular weight, uye solution pH.
5. pH: Iyo pH yeCMC mhinduro inogona kukanganisa viscosity yayo nekuda kwekuchinja kwepolymer ionization uye conformation.CMC inowanzoita viscous pane yakakwirira pH kukosha nekuti mapoka ecarboxymethyl akaiswa ionized, zvichitungamira kune kwakasimba kwemagetsi repulsions pakati pepolymer cheni.Nekudaro, yakanyanyisa pH mamiriro anogona kutungamira kune shanduko mukunyungudika kwepolymer uye conformation, izvo zvinogona kukanganisa viscosity zvakasiyana zvichienderana neiyo CMC giredhi uye magadzirirwo.
6. Munyu Yemukati: Kuvepo kwemunyu mumhinduro kunogona kukanganisa viscosity yeCMC mhinduro kuburikidza nemhedzisiro yekupindirana kwepolymer-solvent uye ion-polymer kusangana.Mune zvimwe zviitiko, kuwedzerwa kwemunyu kunogona kuwedzera viscosity nekuongorora electrostatic repulsions pakati pepolymer cheni, nepo mune dzimwe nguva, inogona kuderedza viscosity nekukanganisa kupindirana kwepolymer-solvent uye kukurudzira kuunganidzwa kwepolymer.
7. Shear Rate: Iyo viscosity yeCMC mhinduro inogona zvakare kuenderana neshear rate kana chiyero icho kushushikana kunoshandiswa kune mhinduro.Mhinduro dzeCMC dzinowanzo ratidza hunhu hwekuveura-kutetepa, uko viscosity inodzikira nekuwedzera shear rate nekuda kwekurongeka uye kutaridzika kwemaketani epolymer munzira yekuyerera.Huremu hwekugera hutete hunogona kusiyana zvichienderana nezvinhu zvakaita se polymer concentration, uremu hwemamorekuru, uye mhinduro pH.

iyo viscosity ye sodium carboxymethylcellulose mhinduro inokonzerwa nekubatanidzwa kwezvinhu zvinosanganisira kusungirirwa, dhigirii rekutsinhanisa, molecular uremu, tembiricha, pH, munyu, uye shear rate.Kunzwisisa zvinhu izvi kwakakosha pakugadzirisa viscosity yeCMC mhinduro kune chaiwo mashandisirwo mumaindasitiri akadai sechikafu, mishonga, zvizorwa, uye kuzvitarisira wega.
