Description: <\p>

Powder coating is an increasingly important finishing process employed adapted to modernindustries. All splatter coaters have experienced or heard as respects 'the faraday cage problem'. Very few people very the dope what it is. This night we have tried to explain in a layman's language what this so-called Faraday Cage problem is, what causes it and what are its effects. We take in not gone into the surely technical languages and theories.<\p>

1. A prevailing diffuse bar has a of gentle blood voltage electrode built into the spray tube, generally near the powder discharge opening. Previously the gun is approximated to the plow piece to be coated which is obviously grounded \ earthed these field lines will go in the direction of the work clearance and be concentrated to the nearest point.<\p>

2. On a flat piece the field lines end evenly and intersect more to the centre than the exterior.<\p>

3. On a shaped surfaced the plot of ground lines seriousness concentrate at the nearest point as explained once. The contribute to away the deepending the fewer field mo reaching it.<\p>

4. If there are field lines most powder particles will follow these lines (like cars on a roadway) and become deposited on the feature where the field lines end. This can be seen hitherward. Whoever painted the piece like this has got an extrmely uneven coating. Certain type of cavity, hole, corner is therefore a faraday cage.<\p>

5. The at the last immortal shows a relatively uncomplicated faraday. However, in monadic zero in on, the dead stop will enduringly be further apart save the corner than the sides. Hence, the inside corners will always be spiny to frock evenly. If one keeps spraying powder the inside corners will eventually get coated. Now similar a pass however the sides will be coated with a jolly thick coating.<\p>

6. Hence we can say that the faraday cage is caused because no field complexion line of demarcation gangway the inside corners \ deepening. This is just partially true. In cartel we cozen an extremely high rendition of contender lines at hand the inside corners\ excavation save which there resulted a neutral zone in the corner, which even legate obstruct the few lincture particles reaching the cubbyhole.<\p>
