Abstract

The invention provides a method for spraying anticorrosive paint on the inner surface of a ship seawater pipeline. Spraying equipment comprises a paint liquefying device, a high-pressure pump in pipeline communication with the paint liquefying device, a rail fixed through a supporting structure, two walking devices installed on the rail, a hose support and a hose, wherein one walking device is connected with the hose support through an L-shaped connecting rod, the other walking device is provided with a laser curing device, and the laser curing device is located at the circle center of the hose support; one end of the hose is connected to an outlet of the high-pressure pump, the middle of the hose penetrates through a through hole of a connecting block fixedly connected to the bottom of the rail, and the other end of the hose penetrates through a through hole of the hose support and is wound around the outer circumferential surface of the hose support; threaded holes are formed in thepipe wall of the end, located on the outer circumferential surface of the hose support, of the hose; the interior of each threaded hole is connected with a funnel-shaped spraying nozzle; and threads are arranged on the outer surfaces of round pipes at the lower ends of the spraying nozzles. The coating flowing phenomenon caused by non-uniform coating is avoided, so that the purpose of optimizing the spraying effect is achieved.

Description

technical field

[0001] The invention belongs to the field of coatings and coating equipment, and in particular relates to a method for spraying anti-corrosion coatings on the inner surface of naval seawater pipelines. Background technique

[0002] Coatings with anti-corrosion, waterproof and protective functions are very necessary materials in engineering construction. Especially for the protection of pipelines such as underground, road and bridge, tunnel engineering, and ship seawater pipelines, a protective layer needs to be coated and it is hoped that it will be cured soon.

[0003] At present, the construction methods of coatings include various methods such as brush coating, spray coating, roller coating and curtain coating. The brushing method is the most widely used brushing method in construction at present. It is simple in construction and easy to operate, but it requires pure manual operation during construction, which is labor-intensive, does great harm to worker...
