Due to the characteristics of water-based ink, many manufacturers use ultrasonic cleaning to take a pre-soaking method to soften the dry ink residue in the net hole, and then ultrasonic treatment. The pre-soaking liquid is specially equipped with a high PH, which helps to soften the ink residue, and the sonic wave level during ultrasonic treatment can be reduced and achieve the cleaning effect without damaging the mesh. In addition, the ultrasonic emission time can be reduced by 80 to 90 percent.

When cleaning, the mesh roller rotates slowly, and the high-frequency ultrasonic transducer in the liquid pool begins to vibrate. Due to this vibration and the continuous rotation of the roll body, the tiny bubbles in the liquid are constantly close to the roll body, which continuously produces burst and vibration. Under the action of ultrasonic wave, the roller body and the ink residue hidden in the depth of the net hole are constantly shaken and dropped. So as to achieve the purpose of cleaning.
