Melt blown fabric with electrostatic polarizing device (polarizing rod)

Melt blown fabric with electrostatic polarizing device (polarizing rod)It is a processing equipment designed specifically for improving the filtration efficiency of melt blown non-woven fabric filter materials.

This device consists of two parts:

1) Electrostatic generator host

2) Resident level production rod

Melt blown fabric with electrostatic polarizing device (polarizing rod)effect:

After electrostatic polarization treatment, the meltblown fabric increases electrostatic adsorption during air filtration. It can directly attract charged particles and capture them by Coulomb force, or induce neutral particles to produce polarity and capture them. This can more effectively filter submicron particles in gas, greatly enhancing filtration efficiency without increasing air resistance.
Since the outbreak of the epidemic, with the increase of domestic production capacity, there has been a strong demand for key raw materials such as meltblown fabrics. Moltblown nonwoven fabrics treated with electrostatic polarization have the advantages of high filtration efficiency and low filtration resistance due to their persistent static electricity, which can capture fine dust through electrostatic effects. At present, electrostatic polarization equipment in the melt blown non-woven fabric industry has been widely used in various non-woven fabric manufacturers and equipment manufacturers. The melt blown fabric electrostatic generator and melt blown fabric electrostatic polarization equipment are accelerating their supply to assist in the production of melt blown fabric.

In situations where it is not immersed in rainwater.

Melt blown fabric with electrostatic discharge device (electrostatic discharge rod)characteristic:

1. The charging effect of an electrostatic generator is closely related to the structure and installation of the ion emitter (rod), and generally the ion emitter (rod) needs to be customized on site.

2. Do not use electrostatic generators in flammable and explosive environments.

3. The grounding terminal of the electrostatic generator must be truly grounded, otherwise it will affect the charge effect and generate unsafe factors.

4. Do not aim the firing pin of the electrostatic emitter (rod) at the human body.

5. The electrostatic generator has a short-circuit protection device inside, but frequent short-circuit ignition of the output should be avoided, otherwise the protection device may also be damaged due to fatigue.

Melt blown fabric with electrostatic discharge device (electrostatic discharge rod)matters needing attention:

1. The discharge needle of the electrostatic emitter should be kept away from the metal mounting bracket of the emitter, and an insulating material should be used as the bracket.

2. In order to apply sufficient static electricity to the material, there must be a flat "metal pallet" or "metal mesh plate" on the back of the material to be charged with static electricity. This metal support plate is connected to the "earth", which is the working grounding of the DC high-voltage supply, in order to form a "circuit" for electrostatic discharge.

3. In order to add sufficient static electricity to the material and prevent it from leaking (escaping) quickly after adding static electricity. The higher the insulation value of the material, the better. The drier the materials and ambient air, the better.

4. Do not discharge the electrostatic discharge needle towards the bare metal plate, as the area of the material subjected to static electricity is equal to the area of the metal plate. If the area size of the material to be electrostatically charged changes and the area or length of the electrostatic emitter cannot be changed, then place a thick insulating material on the bare metal support plate to cover it, or cover the discharge needle facing the bare metal support plate, which is conducive to the concentration of charges on the material that needs to be electrostatically charged.

5. Good operational performance, the magnitude of voltage and current determines the adsorption force of meltblown fabric

6. Stable and reliable. Due to the unstable operation of the equipment under high voltage, it is highly susceptible to damage.

7. Ensure the safety of the electrostatic generator as a high-voltage device. Improper selection can pose a risk of electric shock to the human body.

Both too large and too small can affect the production process of meltblown fabric. The use of non electric shock technology, overload protection technology, and continuously adjustable voltage and current technology is the preferred choice for non-woven meltblown fabric with electrostatic equipment.
