At present, with the continuous rising of real estate grades, the varieties of building coatings are continuously updated, the types of building coatings are more and more, and especially colorful coatings become mainstream products for exterior wall coating by the fake and genuine stone-like effect.
The multi-color paint is a multi-color mixed paint which is coated into particles by a plurality of single-color paints through protective glue, and the colors of the multi-color mixed paint are mutually incompatible, and the multi-color paint can be sprayed with multi-color effect by one gun. Because the soft granules are composed of a plurality of single-color soft granules, the construction requirement is higher, otherwise the granules are easily unclear, broken and even mixed into one color.
As the colorful paint is a new technical product, no special spraying spray gun is available on the market. The existing spray gun for the traditional single-color coating is a solid gun needle and multi-channel air supply mode, the air supply mode can enable the coating to be fully atomized, the coating is fine and uniform, the required effect of spraying the colorful coating is just to ensure the integrity of particles, and the particle reduction and even particle color mixing caused by atomization are reduced. The spray gun is suitable for spraying single-color paint, and the multicolor paint consists of a plurality of single-color soft particles, and loses the multicolor effect once atomized, so that the atomization hood at the nozzle of the spray gun is required to be removed to reduce atomization when the traditional spray gun is used for spraying the multicolor paint. Although atomization of spraying can be reduced, airflow of the spray gun is conveyed by the porous air duct, and spraying of granular multicolor paint is still not facilitated, so that a special spray gun for multicolor paint is urgently needed in the market.
Meanwhile, as the air source provided by the air compressor has large fluctuation, the commercially available paint pressure barrel is a single pressure reducing valve pneumatic assembly, the paint outlet flow and the air volume with stable pressure of the colorful paint cannot be accurately controlled, and the colorful paint is easy to mix colors, so that the requirements on the stability of the air volume pressure and the paint flow are high, and a site operator needs to adjust the spray gun in time to ensure the stable spraying along with the change of the flow and the air volume pressure of the colorful paint. This has not only increased the construction degree of difficulty, has also influenced the efficiency of construction, and the effect of construction also changes along with constructor level simultaneously.
