We all know that the paint transfer efficiency of electrostatic spraying can be as high as 50% - 70%. However, in addition to paint, what other factors affect the efficiency of electrostatic spraying? How can we improve the efficiency of electrostatic spraying?
1、 Main influencing factors of electrostatic spraying efficiency
1. The distance between the rotating cup (or spray gun) and the target (i.e. the coating) is usually 250 ~ 300 mm.
2. Electrical conductivity of paint materials. When the paint resistance is not less than 1mq, it can produce good electrostatic effect. The electrostatic effect of high conductivity coatings is poor, so electrostatic spraying is not recommended.
3. Operating voltage. Generally, the higher the voltage is, the higher the theoretical transmission efficiency is. In practice, the efficiency of electrostatic spraying is also affected by other factors.
