Rheological Property yeMethyl cellulose Solution

Iyo rheological properties yemethylcellulose (MC) mhinduro yakakosha pakunzwisisa maitiro ayo uye kuita kwayo mumashandisirwo akasiyana siyana. Iyo rheology yechinhu inoreva kuyerera kwayo uye deformation maitiro pasi pekushushikana kana kushushikana. Iyo rheological zvimiro zveMC mhinduro zvinogona kukanganiswa nezvinhu zvakaita sekutarisa, tembiricha, pH, uye dhigirii rekutsiva.

Viscosity

Viscosity ndeimwe yeakanyanya kukosha rheological zvimiro zveMC mhinduro. MC chinhu chakanyanya viscous chinogona kuumba makobvu mhinduro kana yanyungudika mumvura. Iyo viscosity yeMC mhinduro inotsamira pakusangana kwemhinduro, dhigirii rekutsiva, uye tembiricha. Iyo yakakwirira yehuwandu hwemhinduro, iyo yakakwirira viscosity yemhinduro. Iyo dhigirii yekutsiva inokanganisawo viscosity yeMC mhinduro. MC ine dhigirii repamusoro rekutsiva ine viscosity yepamusoro kana ichienzaniswa neMC ine yakaderera dhigirii yekutsiva. Iyo tembiricha inogona zvakare kukanganisa viscosity yeMC mhinduro. Iyo viscosity yeMC mhinduro inoderera nekuwedzera tembiricha.

Shear Kuonda Behaviour

MC mhinduro dzinoratidza shear-kuonda maitiro, zvinoreva kuti viscosity yavo inodzikira pasi pekunetseka kwekugera. Kana shear stress inoshandiswa kune MC solution, viscosity inoderera, zvichiita kuti mhinduro iende nyore nyore. Ichi chivakwa chakakosha mumashandisirwo apo mhinduro inoda kuyerera nyore panguva yekugadziriswa, asi inodawo kuchengetedza ukobvu hwayo uye kugadzikana kana ichizorora.

Gelation Behaviour

MC mhinduro dzinogona kupinda gelation kana ichipisa pamusoro peimwe tembiricha. Ichi chivakwa chinoenderana nehuwandu hwekutsiviwa kweMC. MC ine dhigirii repamusoro rekutsiva ine tembiricha yepamusoro yegelation kana ichienzaniswa neMC ine yakaderera dhigirii yekutsiva. Iyo gelation maitiro eMC mhinduro akakosha mumashandisirwo akadai sekugadzirwa kwejels, jellies, uye madhiri.

Thixotropy

MC mhinduro dzinoratidza thixotropic maitiro, zvinoreva kuti viscosity yavo inoderera nekufamba kwenguva kana vakazorora. Kana shear stress inoshandiswa kune mhinduro, viscosity inowedzera.
