A. The paint film has good quality, the coating is smooth and delicate, and there is no brush marks. It sprays the paint into a fine particle to make it evenly distributed on the surface of the wall, so that the latex paint forms a smooth, smooth and dense coating on the wall surface, without brush marks and rolling marks. This is brush and roll. The original method is unmatched.
B. High coating efficiency. The single-action operation has a spraying efficiency of 200-500 square meters per hour, which is 10-15 times that of manual brushing.
C, good adhesion, long coating life. It utilizes high-pressure jetting to obtain powerful kinetic energy of the atomized paint particles; the paint particles are used to absorb the kinetic energy into the pores to make the paint film denser, thereby enhancing the mechanical bite force between the paint film and the wall surface and improving the adhesion of the paint. , effectively extend the life of the coating.
D, the film thickness is uniform, and the coating utilization rate is high. The thickness of the artificial brush roller is extremely uneven, generally 30-250 micrometers, and the coating utilization rate is low; and the air-free spray coating is easy to obtain a coating having a thickness of 30 micrometers.
E, easy to reach the corners and gaps. Due to the high-pressure airless spray, the paint spray does not contain air, and the paint easily reaches the corners, cracks, and uneven and difficult parts, especially for office ceilings with many air-conditioning fire pipes, but the roller brush is difficult to construct.
F, can spray high-viscosity coatings, while hand brush, air spray, etc. are only suitable for low-viscosity coatings. With the development of the economy and the change of people's concept, it has become fashionable to use domestic and high-grade interior and exterior wall paint instead of mosaics and ceramic tiles to decorate the wall. Water-based latex paint has become the most popular interior and exterior wall decoration material due to its non-toxicity, convenient cleaning, rich color and no pollution to the environment. But latex paint is a very high viscosity waterborne coating. At the time of construction, the general manufacturer has very strict restrictions on the dilution of the original paint with water, generally 10%-30% (except for special formula coatings which can add a little water without affecting the performance of the coating, which will be written on the product manual). The transitional dilution will result in poor film formation, and its texture, scrub resistance and durability will be damaged to varying degrees. The degree of damage is proportional to the dilution, ie the greater the dilution, the worse the quality of the film. If strictly according to the manufacturer's dilution requirements, the latex paint has high viscosity and is difficult to construct. If it is applied by roller coating, brush coating or air spraying, the paint surface effect is difficult to satisfy. The most popular way in foreign countries is to use high-pressure airless sprayers for construction.
