Usage and precautions of meltblown cloth electrostatic electret

What is meltblown cloth electrostatic electret?
The process of meltblown cloth electrostatic electret is to add inorganic materials such as tourmaline, zirconium phosphate and silicon dioxide into PP polypropylene polymer in advance, and then charge the melt blown material by one or more groups of corona discharges with a voltage of 5-10kv on the needle electrode of an electrostatic generator before rolling the cloth. When a high voltage is applied, the air below the needle tip will generate corona ionization and generate partial breakdown discharge. Carriers will pass through the action of an electric field, And is deposited on the surface of the meltblown cloth.

When using the meltblown cloth electrostatic electret, you must master the correct method and never use it without following the steps, otherwise it will cause great equipment loss and make the user lose more than he gains. But then again, what is the use method and steps of meltblown cloth electrostatic electret? What are the precautions when using?

First, learn how to use the electrostatic electret of the lower meltblown cloth:
1、 Use meltblown cloth electrostatic electret equipment  to power on and off . Press the [on / off] switch to the [on] position when powered on. Power off is to press the [on / off] switch to the [off] position.

2、 Next, it should be noted that the specific use of starting and stopping the high-voltage output of the melt blown cloth electrostatic electret device is to start the high-voltage output, then press the button and lock it, and the built-in indicator light is on.

3、 If the high-voltage output is stopped during use, select the button to pop up and unlock, and the built-in indicator light will go out. This is how to use this kind of electrostatic equipment. I hope users can understand it in detail.

Precautions for using meltblown cloth electrostatic electret:
1、 The output voltage of the high-voltage supplier of the meltblown cloth electrostatic electret equipment shall meet the requirements. If the voltage is too high, it will cause ignition and breakdown, affecting the normal operation of the equipment and potential safety hazards.

2、 The high-voltage supply of the meltblown cloth electrostatic electret equipment is internally equipped with a large capacity capacitor. After the high-voltage supply is powered off, when the discharge rod is overhauled, it is necessary to stop the machine for a sufficient time or use a wire to ground and discharge the electrode before touching the discharge needle.

3、 Rotate the hand wheel of the voltage regulator at a constant speed from zero to boost the pressure. The boosting methods include: fast boosting method, i.e. 20 s step-by-step boosting method; Slow boosting method, i.e. 60s step-by-step boosting method; Very slow boosting method is available. After the voltage rises from zero to 75% of the rated test voltage you need by a certain boosting method and speed, it rises to the test voltage you need at the speed of 2% of the rated test voltage per second, and pay close attention to the situation of the measuring instrument and the tested object. If the indication of the measuring instrument and the condition of the test object are found abnormal during the boosting process or the test, the voltage shall be reduced immediately, and the power supply shall be cut off to find out the situation.

After reading the use methods and precautions of meltblown cloth electrostatic electret, if you want to buy a quotation of high-quality electrostatic generator, it is still recommended that we consult with regular large manufacturers. LISUN launched ESD-RPB Meltblown cloth electrostatic electret generator is composed of a pin-type electrostatic rod and a high-voltage DC power supply. The high-voltage DC power supply provides high voltage for ion emission, which causes the pin-type electrostatic bar to emit negative (positive) ions, and then charges objects such as melt-blown cloth. According to AATCC42,  ASTM F1862-17, ASTM F2299-03 (2017), ASTM F2100-2019, BS EN14683-2019, BS EN 14387-2004+A1 2008, BS EN 136-1998, BS EN 140-1999, BS EN 143-2000 +C1-A1, BS EN 149-2001+A1, etc. It is widely used in non-woven fabrics, printing, film sticking, paint spraying, flocking, sorting and biological engineering and so on.
