Polyurethane spraying-FAQ and Solution

1. The material flows on the wall:

Cause: slow material speed, or poor material atomization, uneven spraying.

Solution: Adjust the equipment, improve heating temperature of pipeline, and improve heating capacity of the equipment.

2. Unsmooth foam surface:

Cause: Disordered material speed, deformed gun nozzle, spraying too thickly at one time.

Solution: Adjust the equipment, clean the material residue inside the gun nozzle, and improve air supply pressure.

3. Low material output:

Cause: bad environment conditions, low environment temperature, high wind speed, more black material, etc., all these cause low material output.

Solution: Improve material temperature, shield the window to reduce loss, and decrease construction under the windy weather.

4. Poor adhesion of material:

Cause: dust of base body, low temperature of base layer, etc.

Solution: Blow off the dust on the base body and improve low temperature of the base layer.

5. Gun blocking:

Cause: Impurities enter white material or water enters the black material to form crystal. The fed material is imbalanced.

Solution: Reduce heating temperature of equipment, check if the pipeline of black material and white material is blocked.
