Efficacy and application of electret masterbatch

How to distinguish which masks

Does it have the function of blocking viruses?

Why is electret masterbatch so important?

01 Efficacy and application

Can the melt-blown cloth with electret masterbatch achieve 95% or higher filtration efficiency?

A good high-quality melt-blown cloth is related to material, melt-blown process, voltage, etc., so the achievement of N95 standard is not necessarily related to electret masterbatch.

The greatest effect of electret masterbatch is to help us meet the N95 standard of this melt-blown cloth to store charge and extend its validity!

For example, our country has a technical standard for new energy vehicles, which is the range. This requires an efficient and durable battery to continuously provide electric energy to meet the requirements.

To conduct electret treatment for melt-blown cloth is equivalent to charging melt-blown cloth and storing more electric charges. The electret masterbatch is the battery of our meltblown cloth!

Classification of masks

First of all, take a look at the classification of masks. The masks are divided into ordinary gauze masks, daily protective masks, industrial dust masks and medical masks. The ordinary gauze masks have good cold, warm and breathability, and can block some dust. The daily protective masks are mainly PM2.5, flower powder, and other things. The industrial dust masks are mainly used to isolate dust and other things in the process of industrial production, It plays a protective role in occupational protection.

In the classification of masks, only medical surgical masks and medical protective masks in medical masks can effectively block bacteria and viruses in the air.

For medical masks, they are generally divided into three layers: the first layer is waterproof and bactericidal layer, the second layer is filter electret layer, and the third layer is absorbent and skin-friendly layer. The main function of virus filtering for the mask is the extremely fine and electrostatic middle layer filter cloth - melt blown non-woven fabric. Melt-blown cloth is the core material of mask. The medical mask and N95 mask are composed of spunbonded layer, meltblown layer and spunbonded layer.

The second layer of electret melt-blown cloth with electret masterbatch and electret high-voltage electrical treatment is the core part. Only after electret treatment, many charges on the melt-blown cloth can have efficient adsorption effect on 0.3 micron virus particles with the same charge, which usually requires more than 95%. In order to store this static electricity, the composition and structure of the material should be such that the electret is conducive to charge retention. In the process of electrostatic storage and charge retention, the addition of electret masterbatch plays a crucial role.

Its magic lies in that adding a small amount of electret masterbatch can increase the density and depth of the charge trapping energy trap in the melt-blown nonwoven fabric, effectively release negative ions and store charges to improve the comprehensive filtration efficiency and anti-heat attenuation performance of the melt-blown nonwoven fabric. It can reduce the resistance of non-woven products and improve the filtration efficiency of non-woven products under the same fiber fineness and weight.

What is N95 mask?

nder the specified conditions, the aerosol filtration rate of Staphylococcus aureus reaches more than 95%. Only a mask meeting this standard can effectively protect bacteria and viruses, which is the origin of the concept of N95 mask.

02 Electret masterbatch

It is necessary to use good melt-blowing materials, good melt-blowing equipment and melt-blowing process, and have enough voltage to apply static electricity. At this time, the electret masterbatch is needed!
