Normal operation

For a stable process this amount must be constantly re-filled, at best as continuously as possible.
One requires around 0.5 - 1 litre of additive per wheel and hour of blasting and for pneumatic blasters also around 0.5 - 1 litres per blasting tube and hour of blasting.

When adding the additive manually, ensure that it can be thoroughly mixed with the blasting abrasive—for example, by introducing the cleaning agent directly into the abrasive hopper.
For process reliability reasons, the automatic metering with a doser is preferable.

Regularly performing a process control, for example when possible by repeating the water penetration test, provides simple quality assurance support. The blasting process can be evaluated at any time according to the requirements for the blasted surfaces on the basis of the required penetration time, the seepage behaviour of the water, and, if necessary, altered according to the blasting results: for example, a maximum penetration time of 60 seconds in the field of surface preparation for corrosion protection coatings.
