Abstract:
A powder spraycoating method and powder spraycoating equipment. A dense phase powder pump is used. According to a predetermined conveying-air function in a control unit, different rates of compressed conveying air can be defined for different powder rates. In one predetermined total-air function in the control unit, the sum of total-air rate composed of the rate of compressed conveying air and of the rate of supplemental compressed air can be kept constant even if the rate of compressed conveying air changes.
