The Geotextile production line manufacturer tells you that the PP melt-blown nonwoven fabric with special electret masterbatch is delivered to the fan-shaped nozzle by a high-pressure water pump, and the side of the melt-blown nonwoven fabric is spunlace spray-dried with the fan-shaped nozzle. The friction of the spray cloth generates electric charges, and the hydroentangled electrostatic electret is completed.

Common air filter materials mainly rely on physical and mechanical effects such as Brinell diffusion, interception effect, inertial conflict and natural gravity settlement to block particles in the air.
Geotextile production line manufacturers tell you that at present, in the field of air filter materials, the low resistance of materials is pursued, and low resistance air filter materials are almost all electret materials.
After being treated with electret, the material is used for air filtration. In addition to physical and mechanical functions, the material also has electrostatic adsorption.
Electret material Under the premise of ensuring the same filtration efficiency, the pore size of electret filter material can be larger than that of ordinary filter material.
The electret used by the ultrapure water treatment equipment manufacturer for the melt blown cloth of the water electret equipment refers to the dielectric material with long-term charge storage function. The stored charges can be unipolar real charges (or space charges) injected from the outside, or dipole charges formed by the ordered orientation of dipoles in polar media, or both.
The Geotextile production line manufacturer tells you that when the melt-blown fiber is ejected from the spray hole, if it is attacked by charged protons such as electrons or ions, it can make the melt-blown fiber-based material become an electret; similarly, when When collecting microfiber-based materials, they can be treated by corona treatment, or become electrets.
The electret processor is specially designed to improve the filtration efficiency of melt-blown nonwoven filter materials. It consists of three parts: the main generator, the step-up transformer and the electret processing frame.
The processing machine is combined on the melt-blown cloth production line for online processing or independently processing the finished melt-blown cloth filter material. After high-pressure treatment by the processor, the filtration efficiency of the material can be greatly improved.
The Geotextile production line manufacturer tells you that the structure of the electret treatment frame can be customized according to the customer's production site, and the whole set of equipment can meet the needs of different widths of filter materials and production line speeds.
