Powder flowability
is defined as the ease with which a powder will flow under a specified set of
conditions. Some of these conditions include: the pressure on the powder, the
humidity of the air around the powder, and the equipment the powder is flowing
through or from.
Powder Flow Rate
or Ejector : Too High
- High impact fusion
- High venturi wear
- Low transfer efficiency
- Poor penetration into recesses – low wrap
Powder Flow Rate
or Ejector: Too Low
- Powder spurting, surging, or puffing
- Low powder film build
- Poor penetration into recesses
Controlling the powder flow rate is a critical step required
to create accurate process control. Spray
equipment can be complicated, so if you need some additional assistance with
your spray equipment and controlling powder flow rate, feel free to contact us today and we
will be more than happy to help.
