1. Causes of static producing; Under the action of certain friction electron will transfer from one grinding surface to another surface and lead the electric charge at the surface of article to produce local imbalance and static voltage and produce static.

2. Harm caused by static

1) Touching disturb caused by static at peacetime.

2) Fire

3) Dust explosion

4) Lead damage of electronic elements

3. Reasons and principle of adapting conductive FIBCS(Anti-static FIBCS) During the potting and discharging period of powder material, it will produce static. If the static charge is accumulated to certain amount, it will produce static voltage. Once there is spark or strong light, dust powder explosion or static explosionwill be produced and so much as fire will be produced. Based on the principle of creating adcanced technique in the world and revival national industry, Changzhou Jicheng Plastic Co., Ltd. has developed the Conductive FIBCS (Anti-static FIBCS)though hardship work for two years. It adapts one grounding device to lead static to earth. Its surface resistance will be ≤108Ω and its grounding resistance will be ≤108Ω . Under 1KV voltage, its surface resistance ≤108Ω and its grounding resistance≤108Ω, so that the static charge produced during the the potting and discharging period of powder materialwill be led to earth in time and avoided the disasters taking place mentioned above.
