Common problem.

Static damage: Chrome needs antistatic protection, otherwise there will bedamage by static electricity (see chart), generally chromium version store and use environmental instantaneous electrostatic value can not be higher than500V, can make the electrostatic protection in accordance with the followingrequirements:

1, the generation of static electricity: attachment material between contact and separation, electrostatic induction, dielectric polarization and charged particles.

2, the electrostatic hazard: the attraction or repulsion, and the earth have thepotential difference, meets the conductive body discharge current, the chromiumlayer heat damage.

3, the characteristics of electrostatic hazards: concealment, potential,randomness, complexity.

4, antistatic:

1) the use of anti-static materials - electrostatic conductive material (surfaceresistivity of <; 105 Ω / □); static dissipative materials (surface resistivity of 105~1012 Ω / □); anti static electricity powder materials (surface resistivity of 109~1014 Ω /
