News Detail
1. Spraying machine coating quality is good, the coating is smooth and fine, without brush marks. It will paint pressurized spray atomization into fine particles, so that it is evenly distributed on the wall surface, so that latex paint on the wall to form a smooth, smooth, dense coating, no brush marks, roll marks, which is brush, roll and other original methods incomparable.
2. Spraying machine has high efficiency. The spraying efficiency of single operator is as high as 200-500 square meters/hour, which is 10-15 times that of manual brushing.
3. Spraying machine has good adhesion and long coating life. It uses high pressure jet to make atomized coating particles obtain strong kinetic energy; The coating particles take this kinetic energy to shoot into the pores, so that the film is more compact, so as to enhance the mechanical bite force between the film and the wall, improve the adhesion of the coating, effectively extend the life of the coating.
4. Uniform coating thickness with high utilization rate. The thickness of manual brush roller is very uneven, generally in 30-250 microns, low utilization rate of paint; The coating thickness of 30 microns is easily obtained by airless spraying.
5. There is easy access to corners and gaps for spraying. Due to the use of high pressure airless injection, paint spray does not contain air, paint is easy to reach corners, gaps and uneven brush parts, especially for a lot of air conditioning fire pipe office ceiling is more suitable, roller brush is difficult to construct.
6. Mortar spraying machine is available for spraying high-viscosity coatings, while hand brush, air spraying etc are only suitable for low-viscosity coatings. Water-based latex paint, because of its non-toxic, easy to clean, colorful, do not cause pollution to the environment, and began to become the most popular interior and exterior decoration materials. But latex paint is a kind of waterborne paint with high viscosity. Excessive dilution will lead to poor film formation, its texture and scrub resistance, durability will be damaged in different degrees. The destruction degree is proportional to the dilution, that is, the larger the dilution, the worse the film quality. If strictly press the dilution requirement of manufacturer, latex paint viscosity is very high, construction difficulty is big. Such as roller coating, brush coating or air spraying construction, the finish effect is difficult to be satisfactory. The most popular way in foreign countries is to use high pressure airless spray machine to construct.
