Abstract

The invention discloses an electret ultrasonic sputtering liquid charging device and a charging method. In the ultrasonic sputtering charging device of the electret, the liquid tank is trapezoidal, the bottom of the liquid tank and the horizontal plane form an angle of 20-65°, and the material that can be electret enters from the bottom of the liquid tank through the unwinding device. The liquid tank, through the first roller shaft and the second roller shaft, the electret material can be attached to the bottom of the liquid tank, and at the same time, ultrasonic waves can be applied to the bottom of the liquid tank filled with polar liquid and materials that can be electret. After the electret material leaves the liquid tank, it is dried by a drying device to obtain a charged electret. This method can adjust the distance between the first roller shaft, the second roller shaft and the bottom of the liquid tank, and change the inclination of the bottom of the liquid tank, so that the electret materials with different thicknesses and different materials can be laminated easily. , Efficient, stable and uniform charging.

Description

technical field

[0001] The invention relates to an electret liquid charging device and a charging method, in particular to an electret ultrasonic sputtering liquid device and a charging method. Background technique

[0002] Traditional air filter materials mainly rely on physical and mechanical effects such as Brownian diffusion, entrapment effect, inertial collision, and natural gravity sedimentation to block particles in the air. At present, in the field of air filter materials, the pursuit of high efficiency and low resistance of materials, and the air filter materials that can achieve high efficiency and low resistance are almost all made of electret materials. The material after electret treatment is used for air filtration. In addition to physical and mechanical functions, it also has electrostatic adsorption. Under the premise of ensuring the same filtration efficiency, the pore size of the electret filter material can be larger than that of ordinary filter materials...
