FY-0653S Emulsified Asphalt Particle Charge Tester, also commonly called emulsified asphalt charge tester, emulsified asphalt particle ion charge tester, the following is a related introduction:

Purpose

FY-0653S Emulsified Asphalt Particle Charge Tester is mainly used to determine the charge properties of various types of emulsified asphalt particle ions, that is, to determine whether they are cationic or anionic types.

Working Principle

By inserting electrodes into the asphalt emulsion, a DC 6V electric field is applied. Under the action of the electric field, positively charged particles will move to the negative electrode, and negatively charged particles will move to the positive electrode. After a certain period of time, observe the adsorption of asphalt particles on the electrode plate to determine the particle ion charge polarity of the emulsified asphalt. If a large number of asphalt particles are adsorbed on the negative electrode plate, it means that the asphalt particles are positively charged and the asphalt is cationic; conversely, if a large number of asphalt particles are adsorbed on the positive electrode plate, it means that the asphalt particles are negatively charged and the asphalt is anionic.

Instructions

Preparation: Filter the emulsified asphalt sample with a 1.18mm pore size sieve and place it in a 300ml clean beaker with a liquid level of not less than 30mm. Wash and dry the electrode plate, put down the electrode plate bracket, and insert the electrode plate into the emulsified asphalt for about 30mm.
Connection and setting: Connect the two leads of the instrument controller to the two electrode plate connection columns, turn on the power switch, and set the test time to 3min.
Test: Press the "Start" button to start the test. After three minutes, the instrument automatically stops working.
Result observation: Turn off the power switch, raise the electrode plate bracket, carefully observe the electrode plate, and judge the charge properties of the emulsified asphalt based on the adsorption of asphalt particles on the electrode plate.
