Rheological Property yeMethyl cellulose Solution

Methyl cellulose (MC) mhinduro dzinoratidza yakasarudzika rheological zvimiro zvinoenderana nezvinhu zvakaita sekutarisa, kurema kwemamorekuru, tembiricha, uye shear rate. Heano mamwe akakosha rheological maitiro emethyl cellulose mhinduro:

1. Viscosity: Methyl cellulose mhinduro dzinowanzo ratidza yakakwira viscosity, kunyanya munzvimbo dzakakwirira uye tembiricha yakaderera. Iyo viscosity yeMC mhinduro inogona kusiyanisa pamusoro pehupamhi, kubva yakaderera-viscosity mhinduro dzakafanana nemvura kune yakanyanya viscous gels yakafanana nezvinhu zvakasimba.
2. Pseudoplasticity: Methyl cellulose mhinduro dzinoratidza pseudoplastic maitiro, zvichireva kuti viscosity yavo inoderera nekuwedzera shear rate. Kana ikaiswa kushushikana kweshear, cheni dzepolymer dzakareba mumushonga dzinoenderana nekwainoyerera, zvichideredza kuramba kuyerera uye zvichiita kuti shear iite hunhu.
3. Thixotropy: Methyl cellulose mhinduro dzinoratidza thixotropic maitiro, zvichireva kuti viscosity yavo inoderera nekufamba kwenguva pasi pekugara kweshear kunetseka. Pakupera kwekugera, macheni epolymer mumhinduro zvishoma nezvishoma anodzokera kune yavo yakasarudzika, zvichitungamira kune viscosity kupora uye thixotropic hysteresis.
4. Tembiricha Sensitivity: Iyo viscosity yemethyl cellulose mhinduro inokanganiswa netembiricha, ine tembiricha yakakwira kazhinji inotungamira kune yakaderera viscosity. Nekudaro, iyo chaiyo yekutsamira tembiricha inogona kusiyana zvichienderana nezvinhu zvakaita sekutarisa uye uremu hwemamorekuru.
5. Shear Kuonda: Methyl cellulose mhinduro dzinoita shear kuonda, uko viscosity inodzikira sezvo shear rate inowedzera. Ichi chivakwa chinonyanya kubatsira mukushandisa senge machira uye zvinonamira, uko mhinduro inoda kuyerera zviri nyore panguva yekunyorera asi inochengetedza viscosity pakumira kweshear.
6. Gel Formation: Pakukwirisa kwakanyanya kana nemamwe mamakisi emethyl cellulose, mhinduro dzinogona kuumba gels pakutonhora kana nekuwedzera kwemunyu. Aya gel anoratidza maitiro akasimba, ane viscosity yakakwirira uye kuramba kuyerera. Gel kuumbwa kunoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira mishonga, zvigadzirwa zvekudya, uye zvinhu zvekuchengeta munhu.
7. Kuenderana neZviwedzerwa: Methyl cellulose mhinduro dzinogona kugadziridzwa nezvinowedzerwa zvakaita semunyu, ma surfactants, uye mamwe mapolymers kushandura rheological maitiro. Izvi zvinowedzera zvinogona kukanganisa zvinhu zvakaita seviscosity, gelation maitiro, uye kugadzikana, zvichienderana nezvinodiwa zvekugadzira.

methyl cellulose mhinduro dzinoratidza dzakaomarara rheological maitiro anoratidzwa nepamusoro viscosity, pseudoplasticity, thixotropy, tembiricha senitivity, shear kuonda, uye kuumbwa kwegel. Izvi zvivakwa zvinoita kuti methyl cellulose iwande kune akasiyana maapplication, anosanganisira mishonga, zvigadzirwa zvekudya, machira, zvinonamira, uye zvinhu zvekuchengeta munhu, uko kwakakosha kudzora viscosity uye mafambiro ekuyerera.
