Test Standard-ASTM e466 Sodium Carboxymethylcellulose

ASTM E466 ndiyo yakajairwa bvunzo nzira inopa maitiro ekuona viscosity ye sodium carboxymethylcellulose (CMC) mumvura kana zvimwe zvinonyungudutsa. Iyi nzira inowanzoshandiswa kuyera dhigirii repolymerization uye nhanho yekutsiviwa kweCMC, pamwe nekuona kuenderana kwemasamples eCMC kune zvinangwa zvekudzora kunaka.

Iyo nzira yekuyedza inosanganisira kugadzirira mhinduro yeCMC mumvura kana imwe yakakodzera solvent uye kuyera viscosity yayo uchishandisa viscometer. Iyo viscosity inoyerwa pane yakatarwa tembiricha uye shear rate, iyo inotsanangurwa muyero. Iyo chiyero inopawo nhungamiro yekugadzirira iyo CMC mhinduro, pamwe nemirairo yekuenzanisa uye kushandisa viscometer.

Pamusoro pekuyera viscosity, iyo ASTM E466 yakajairwa inosanganisirawo maitiro ekuyera zvimwe zvivakwa zveCMC, senge pH, madota, uye hunyoro hwemukati. Izvi zvivakwa zvinogona kukanganisa kuita kweCMC mumashandisirwo akasiyana siyana, uye zvakakosha kuve nechokwadi kuti zvinosangana nezvinodiwa.

Pakazere, iyo ASTM E466 yakajairwa inopa yakamisikidzwa uye yakavimbika nzira yekuyera viscosity uye zvimwe zvimiro zve sodium carboxymethylcellulose. Izvi zvinobatsira kuve nechokwadi chekuenderana uye mhando yezvigadzirwa zveCMC uye zvinoita kuti vagadziri vakwanise kuzadzisa zvinodiwa nevatengi vavo mumaindasitiri akasiyana.
