Description
Technical Field
The utility model relates to a spraying equipment field, in particular to high-pressure airless spraying device.
Background
High-pressure airless spraying, also called airless spraying, refers to a spraying mode that paint is directly pressurized by using a high-pressure plunger pump to form high-pressure paint, and the high-pressure paint is sprayed out of a gun mouth to form atomized airflow to act on the surface of an object (a wall surface or a woodware surface).
Compared with air spraying, the paint surface is uniform and has no granular feeling. The paint is dry and clean because the paint is isolated from the air. The airless spraying can be used for the construction of high-viscosity paint, has clear edges, and can be even used for spraying projects with boundary requirements. According to the mechanical type, the painting apparatus is classified into a pneumatic airless painting apparatus, an electric airless painting apparatus, an internal combustion airless spray painting apparatus, and the like.
