Component Specifications

Definition

The emitter points/array is a critical component of an ionizing bar, consisting of sharp metallic tips or a series of emitters arranged in a linear array. It generates a high-voltage corona discharge to ionize surrounding air molecules, producing positive and negative ions that neutralize static electricity on moving webs or surfaces.

Working Principle

High voltage applied to the emitter points creates a strong electric field, causing air breakdown (corona discharge). Electrons are accelerated, colliding with air molecules to produce ions. The ions are attracted to oppositely charged surfaces, neutralizing static charges.

Materials

Tungsten, stainless steel, or silicon; often with gold or platinum coating for corrosion resistance.

Technical Parameters

Length 100-3000 mm
Emitter Spacing 10-50 mm
Point Sharpness < 10 µm radius
Current per Point 10-100 µA
Operating Voltage 5-15 kV AC/DC

Standards

ISO 14644, IEC 61340
