ASTM d244 Lab Bituminous Mixture Emulsified Asphalt Particles Ionic Charge Tester
The particle ionic charge of emulsified asphalt refers to the nature of the charge of dispersed particles in the emulsion, so as to determine the type of emulsion, cationic emulsified asphalt with positive charge and anionic emulsified asphalt with negative charge. This instrument determines the particle ionic charge polarity of emulsified asphalt by inserting electrodes into the asphalt emulsion, applying the electric field of DC 6V, and depending on the movement and attachment of ions.
