It is high-pressure discharge, the charge is attached to the melt-blown nonwoven fabric, and the electret treatment makes the filter material fibers charged, combined with the dense characteristics of the melt-blown ultrafine fiber material, so a large number of electrodes are formed between the charged fibers. It can attract most of the charged particles in the environment like a magnet, and can also polarize some of the uncharged particles, thereby adsorbing some small-size pollutants, and even nanoscale substances such as viruses can be electrostatically adsorbed or charge repels and blocks.

The static electricity generator is composed of an electrostatic emitter and a high-voltage power supply. The high-voltage power supply provides a negative (or positive) high voltage of the electrostatic emitter, so that the electrostatic emitter emits negative-pressure static electricity (or positive-pressure static electricity), and then charges the object or work piece for the process operation. The higher the voltage, the greater the effective range.

The meltblowing die includes a die body, a spinneret and an air plate. The spinneret and the gas plate are detachably installed in the die body. Spinneret holes are provided in the spinneret. There are several grooves on the die and several gas circulation channels in the die. The gas circulation channel is in communication with the tank. The outer wall of the die head is provided with a gas pipe connection end. The connecting end of the trachea passes through the trachea and collects gas. The cavity is connected, one end face of the spinneret hole of the spinneret is fixedly connected with the flow stabilizing element, and the other end face of the spinneret hole is fixedly connected. Equipped with a pipe connection device, and the spinneret hole is connected to the screw extruder through the pipe connection device

How to adjust the temperature of the meltblown machine:
1. If the rubber material stays at high temperature and high pressure for a long time, it is easy to sinter and carbonize.
2. The temperature must first be determined when adjusting the machine, not the display temperature on the machine, but the actual temperature of the barrel and mold. For many small devices, the sensor has not been calibrated, and the displayed temperature and the actual temperature will be very different.
3. For the material with melting index 1500, the temperature is set above 270℃, which is a bit high.

What to do if meltblown cloth becomes brittle and hard
1. Uneven spinning and insufficient air volume of the air cooler will cause uneven heat dissipation and cause internal stress to cause embrittlement. It can be improved by adjusting the melt volume of the extruder, adjusting the temperature of the hot air blower, and increasing the air volume of the cold air blower.
2. Analyzing from the raw material, it may be that the spinneret with low melting fat is used, and the filament is relatively thick. After 24 hours to 48 hours of complete crystallization, the meltblown cloth will become brittle and hard. Meltblown meltblown material is finely spun, soft and evenly distributed, so the meltblown cloth has better flexibility.
3. It has something to do with the high temperature of raw materials and processing. After the fiber is produced, there is a secondary crystallization re-arrangement process inside the PP, which is actually severely heated inside the screw, which has caused severe thermal degradation. If the initiator of the meltblown peroxide process is not well controlled, such problems are prone to occur.
The important thing for the peroxide process is how to complete the molecular chain scission termination before the screw extrusion, to prevent the secondary residue from entering the non-woven screw to continue the reaction, which is a test of the screw equipment combination and formulation control.
4. The melt blown cloth just produced still has a temperature, especially the spraying machine of the large drum rewinding, and there may not be a fan, and the temperature of the melt blown cloth is high after winding. The greater the flexibility and toughness of plastics in high temperature environments, the more brittle they will become after cooling.
5. Add an appropriate amount (2%) of toughening agent
