Coating equipment spraying reason and processing method of foaming:

The reason:

1 coated surfaces wet or acid, salt, salt and other substances.

2 paint and thinner mixed with water.

3 coated surface is too rough, to absorb a large quantity of paint, coating is too thin.

4 site environmental humidity is big, more than 90%, coating is extremely easy to white light loss.

5 live at too low a temperature, drying too slowly, water gathered in the surface caused by the loss of light.

6 air compressor in the moisture is not removed, mixed with the lesions produced in the coating.

7 excessive amount of diluent.

Solution:

1 clean up by impurity coated surface.

2 take good care of paint, prevent mixing water.

3 note the sanding thickness, guaranteed to be coated pages flat.

4 adjust the indoor temperature or stop construction.

5 construction environment in general the temperature above 10 degrees.

6 remove the air compressor in the gas water, maintenance of oil-water separator.

7 adjust the construction ratio.
