Furniture coating water-based paint, refers to water as a solvent or dispersion medium of a coating, in the water-based paint construction process, spraying method is one of the most important ways. So what are the techniques for water-based paint spraying construction?
In China, with the continuous development of society, water-based wood coatings will also get rapid progress, and the emergence of water-based coatings can be said to be the emergence of a new type of paint, I believe that we do not get a comprehensive understanding and understanding of it, not to mention water-based paint spraying construction techniques, but there is no relationship, here small compilation collected a few relevant points for your reference.
In the water-based paint construction process, the surface of the object can be coated with spray method, you can obtain a thin and uniform coating film, for different geometric shapes, there are small holes, gaps, uneven bumps, coatings can be evenly
distributed
;
understand the benefits of water-based coating construction operations, then mastering some operating techniques will also be one of the things consumers need to know.
01
the coating with clean water to the appropriate sprayed viscosity, measured by the application-4 viscosity meter, the appropriate viscosity is generally 20 to 30 seconds. Of course, also not too thick and not too thin, usually paint liquid into a straight line, instantaneously cut off the flow into a drop, this viscosity is appropriate.
Tip 02
In water-based paint spraying construction operation, its air pressure is best within 0.3-0.4 megapa (3-4 kg force /cm2), its pressure is too small, affecting the overall effect, and the pressure is too large, not only waste material but also affect the health of the operator.
technique 03
nozzle and surface distance is generally 300 to 400 mm is appropriate, of course, can also be 10 mm to 50 mm between a small range of adjustment, if not within the range, then it is difficult to obtain the most ideal paint film.
tip 04
spray gun can be made up and down, left and right movement, to 10-12 meters / minute speed even operation for the best, of course, the nozzle should be straight on the surface spray, to minimize oblique spraying.
05
05 when spraying, press down on 1/3 or 1/4 of the upper one so that there is no leakage. When spraying fast dry paint, it needs to be sprayed sequentially at once, and the resaling effect is not ideal.
Tip 06
When spraying outdoors, be sure to pay attention to the wind direction, when the wind is not suitable for water-based paint spraying construction, in order to avoid causing ugly grainy surface, operation workers should stand in the direction of the wind.
Tip 07
In general, in order not to cause the paint mist sprayed after splashing onto the sprayed paint film, damage has been sprayed paint film, water-based paint spray construction operation should follow: first difficult, then easy, first in and out, first high and then low, first small and then big principle.
Consequel
in the paint market, water-based coatings environmental health, construction convenience, has a better corrosion resistance and other advantages, won the same industry and the vast number of consumers recognized and chasing sticks, there is no doubt that it will be the future direction of the paint market, so it is necessary to understand some water-based paint spraying construction techniques.
