Spraying method is one of the most important methods in the construction of waterborne resin coating. It is easy to coat the surface of the object by spraying method. It can obtain thin and uniform coating film. For the different geometrical shapes, there are holes, cracks and ruggedness. Can be distributed evenly; for spraying large surface, this method is more rapid and effective brushing. But with the spray method for construction also need to master some operational skills:
First, with a clean water to adjust the paint to the appropriate viscosity of the coating to test -4 viscometer measurement, the appropriate viscosity is generally 20 seconds to 30 seconds.
The gun can be used up and down, left and right movement, preferably 10 to 12 m / min speed uniform operation, the nozzle should be flat in the surface spray, try to reduce the oblique spray. When sprayed at both ends of the surface, the button to pull the gun to quickly loose, because the ends of the object, often to accept more than two times the spray, is the most likely to cause sagging place.
Fifth, when spraying, the next one to suppress on a 1/3 or 1/4, so that it will not leak phenomenon. Spray fast-drying paint, the need to spray the order in a row, filling effect is usually not ideal.
Sixth, in the outdoor open place to spray, pay attention to the wind (the wind is not suitable for work), the operator should stand in the direction of the wind, to prevent the mist from being blown to the sprayed film caused by ugly granular surface.
Seventh, spray the order is: first difficult after the first, after the first outside. The first high after the low, the first small area after a large area, so that will not cause the spray after the spray fog spray has been sprayed on the film, the damage has been sprayed good film.
