XW-100 thermostatic slurry dispersing machine is specially designed by DAYO for batch preparation of electrocatalyst. It has the advantages of temperature control, good dispersion uniformity and easy to use. In view of the phenomenon of excessive temperature rise and catalyst sedimentation during ultrasonic dispersion of electrocatalyst, XW-100 constant temperature slurry dispersion machine successfully solved such problems, realized constant temperature and continuous dispersion during ultrasonic dispersion process, and ensured the quality of slurry.

Ultrasonic dispersion refers to the process of dispersing and reuniting the particles in the liquid through the "cavitation" effect of ultrasonic wave in the liquid as the medium.

The advantages of our special dispersing machine are:

The ultrasonic power is large, which will stimulate a stronger cavitation effect in the liquid, so that the dispersion effect is better;

The resulting acoustic cavitation effect is more uniform and has no dead Angle;

Circulating cooling water can be connected to control a relatively accurate constant temperature environment.

DAYO product positioning is mainly scientific research grade hydrogen energy testing products, high precision, customized and complete hydrogen energy testing program capabilities are its main characteristics. Its PEM hydrogen production test equipment and fuel cell test equipment have been widely used in major universities, research institutes and leading enterprises in China, and have won praise from customers.
