The emulsified asphalt charge tester is a professional testing instrument suitable for determining the charge properties of various types of emulsified asphalt particles, namely the types of cations and anions.
Technical parameters of SYD-0653 emulsified asphalt charge tester:
★Power supply voltage: DC 6V
★ Large output load: 30mA
★ Timing accuracy: 0.1 second
★ Timing time 3min
★Power supply voltage: 220V<
★ Weight: 10KG
★ Power: 200W
★ Ambient temperature: 5 ~ 40 ° C
★Environmental humidity: ≦85%
SYD-0653 emulsified asphalt charge tester operation method:
★Connect the power cable and electrode connection first. Please pay attention to the electrode connection. The plug should be aligned. The red plug is inserted into the red socket and the black plug is inserted into the black socket.
★ The emulsified asphalt sample was filtered through a 1.18 sieve and filled in a container.
★ Loosen the lock nut of the lifting frame, lift the lifting frame, and place the beaker into the base.
★Inject the filtered emulsified sample into the beaker for about 200ml, and put down the lifting frame so that the electrode plate is inserted into the emulsified asphalt by about 30mm.
★ Turn on the power switch and press the timing button. The LED above the button will be illuminated. At this time, the timer enters the working state, and the timing is 3 minutes.
★When the LED is off, it means the end of the electrode plate is added, you can lift the lifting frame and carefully observe the electrode plate (the red plug is positive and the black plug is negative). If a large amount of asphalt particles are attached to the negative electrode plate, indicating that the asphalt particles are positively charged, the emulsion is cationic, and if a large amount of asphalt particles are adsorbed on the positive electrode plate, indicating that the asphalt particles are negatively charged, the emulsion is anionic.
SYD-0653 emulsified asphalt charge tester instrument and materials:
★ Beaker: 200ml or 300ml.
★ Electrode plate: 2 pieces, made of copper, each plate is 100mm long, 10mm wide and 1mm thick.
★ DC power supply: 6v.
★ Screen: The screen hole is 1.18mm.
★ Others: gasoline, washing liquid, etc.
After the SYD-0653 emulsified asphalt charge tester is finished, if you want to clean the electrode plate, lift the lifting frame, loosen the fixing screws on the conductive column, and remove the electrode plate.
