Product Instruction:

LISUN(Shanghai) ESD-RPBMeltblown cloth electrostatic booster 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 needle electrostatic rod to emit negative (positive) Ions, and then charges objects such as melt-blown cloth. It is widely used in Non-woven fabrics, printing, film sticking, paint spraying, flocking, sorting and biological engineering and so on.

Function Instruction:

since the filtration efficiency of ordinary Melt-blown non-woven fabrics is less than 70%, the mechanical blocking effect of the three-dimensional fiber assembly of pure melt-blown ultrafine fibers with fine fibers, small voids and high porosity is not enough, so melt-blown Filter materials generally add electrostatic charge effect to the melt-blown Cloth through the electrostatic electret process, and use electrostatic methods to improve the filtration efficiency, so that the filtration efficiency can Reach 99.9%, and a thin layer can achieve the expected Standard, breathing Resistance is still small.

the current electrostatic electret methods Mainly include electrostatic spinning method, needle discharge method, Triboelectric method, thermal polarization method, low energy electron beam Bombardment method, etc., among which the needle discharge method is currently The best electrostatic electret method. In the needle discharge method, the Melt-blown fiber web charges the melt-blown material through the corona Discharge of the electrostatic generator needle electrode (generally 5-60KV) Before winding, and the air under the needle tip generates electricity when High voltage is applied Corona ionization, current-carrying ions are deposited On the surface of the meltblown cloth by the electric field. Part of the Carriers will penetrate deep into the surface and be captured by the trap of the Electret masterbatch, thus making the meltblown cloth an electret filter Material.

Increasing the charge on the surface of the Melt-blown cloth can be obtained by the electret treatment process of the Corona discharge method, but to make this electrostatic storage not decay, then The composition and structure of the material of the melt-blown electret Material is needed to help charge retention. The way to improve the charge Storage capacity of electret materials can be to induce charge traps by Introducing additives with charge storage properties. Therefore, compared with Ordinary melt-blown production lines, the production of melt-blown production Lines for air filter materials needs to add electret masterbatch such as Tourmaline particles to the production raw material polypropylene (PP), and Then increase its PFE by means of electrostatic electret Or BFE filterability
