MHEC LH 660 M

EipponCell MHEC LH 660M methyl hydroxyethyl cellulose yog siv hauv cov cement slurry plaster, thiab nws cov viscosity nce tsis tu ncua.Molecular network qauv ntawm cellulose ether intertwines nrog lub network qauv ntawm cement hydration khoom.Thawj hydration ntawm cement tsis ncaj qha nce qhov concentration ntawm cellulose ether, ua rau "composite superposition effect" ntawm viscosity ntawm cellulose ether tov thiab cement slurry.Yog li ntawd, lub viscosity ntawm hloov cement slurry nrog cellulose ether yog ho siab tshaj qhov sum ntawm lawv tus kheej viscosities.

Ob leeg cellulose ether hloov cement slurry thiab ntshiab cement slurry nthuav tawm shear thinning los yog pseudoplastic cwj pwm.Lub pseudoplasticity ntawm cellulose ether hloov cement slurry yog qis dua piv rau cov ntshiab cement slurry.Thaum qis qis qis lossis nrog qis viscosity ntawm cellulose ether hloov cov cement slurry lossis qis cellulose ether cov ntsiab lus, cov pseudoplasticity ntawm cellulose ether hloov cement slurry ua ntau pronounced.

Raws li qhov kub thiab txias, qhov ceev thiab qhov loj ntawm cov cement hydration nce, ua rau maj mam nce hauv viscosity ntawm cov cement slurry.Lub viscosity ntawm hloov cement paste, txawm li cas los xij, nws txawv nrog qhov kub thiab txias vim qhov sib txawv inhibitory peev xwm ntawm ntau hom thiab cov nqi ntawm cellulose ethers ntawm cement hydration.
