Description

1.The significance and necessity of product
It wiil produce a large number of static electricity when the polyolefin powder such as the wind sent to the warehouse. CIBA indicates that when the φ3.4mmPS powder was sent by the wind, charged particles is 1.8~0.48μC/㎏, it will produce frequently conical discharge. The discharge cyclesis is 71~26s and the single discharge of charge transfer is mostly in 26~30μC, the most one is 48μC and the discharge energy is ≤10.4mJ.
