2、 Overview of melt blown fabric electrostatic electret:
Yinxi is a professional manufacturer of high voltage testing equipment and voltage stabilizing equipment. The equipment is easy to operate and easy to move.The high-voltage electrostatic generator of melt blown cloth produced by Yinxi company is used for electrostatic dust removal. It can provide stable power supply for static electret equipment, ensure long-term and efficient work of electret equipment, and provide strong quality assurance for melt blown cloth of grade 90, 95 and 99. It is particularly important to ensure the quality of melt blown fabric.
Electret treatment of melt blown nonwovens is an important finishing technology to improve its filtration efficiency.The melt blown nonwovens with electret finishing have the advantages of high filtration efficiency and low filtration resistance because they have persistent static electricity and can capture fine dust by electrostatic effect.
The electret melt blown nonwovens have good filtration effect on solid dust particles of 0.005 ~ 1 mm, and also have good blocking effect on aerosol, bacteria, cigarette smoke and various pollens in the atmosphere.In the process of melt blown process, the fiber with permanent static charge can be made by using this electrostatic electret device.Polypropylene is an ideal material for electret fiber because of its high resistivity, large charge capacity and low RF loss.Electret air filtration, the filter material fiber itself charged, through electrostatic attraction of charged particles in the air, is also the neutral particles in the air after induction polarization, so as to filter submicron particles in the air more effectively.It can significantly improve the filtration efficiency without increasing air resistance.The filter efficiency of the electrostatic precipitator above 120kv / bfe99 can be achieved.Electrostatic electret device is an electrostatic electret device with processing capacity of 1600mm width. The electrostatic generator is integrated in the interior. The electrostatic electret is connected with 100v120kv DC high voltage. It has the characteristics of high power, long-time operation without heating and high voltage level.(width and height can be customized according to customers)

This equipment is used for the electrostatic adsorption process of melt blown cloth mask.The melt blown fabric electrostatic generator adopts 5KVA / DC: 100kv120kv high voltage operation, which belongs to the equipment with high technical content. The following points should be paid attention to when selecting the non-woven fabric electrostatic generator:
1. Good operation performance, the size of voltage and current determines the adsorption force of meltblown cloth
2. It is stable and reliable. It is easy to be damaged because the equipment works under the unstable state of high voltage.
3. To ensure the safety of non-woven electrostatic generator is a high-voltage equipment, improper selection may cause electric shock hazard to human body.If it is too large or too small, it will affect the production process of melt blown fabric. Adopting non electric shock technology, overload protection technology, continuous adjustable voltage and current technology, it is the choice of non-woven fabric melt blown cloth plus electrostatic equipment
