▎ 摘　　要

NOVELTY - The method involves placing a base material on a spraying device. Shot blasting and sand blasting treatment are performed on the base material after oil stain removal to remove iron scales and iron rust on a surface of the base material. Impurities such as gravel and dust are thoroughly removed on the surface of the base material by using compressed air. A spraying machine table (2) is lifted upwards through a hydraulic rod (5), such that the distance between a spraying nozzle (4) and the base material is maintained at a proper distance. The spraying nozzle is controlled by a horizontal sliding mechanism to horizontally slide along the surface of the base material. A horizontal spraying work of a coating is carried out on the surface of the base material. Multi-coating spraying work is performed on the surface of the base material until the coating on the surface of the base material is completely sprayed. USE - Graphene anticorrosive material anti-drop coating method. ADVANTAGE - The method enables increasing the spraying efficiency and quality of the base material, and strictly controlling the covering distance between each coating, so that the coating is strictly covered on the side of the coating layer during spraying, thus avoiding the occurrence of leakage spraying to ensure the integrity and continuity of coating and avoid the later substrate coating peeling off. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of structure for performing graphene anticorrosive material anti-drop coating. processing machine table (1) Spraying machine table (2) Feeding tank (3) Spraying nozzle (4) Hydraulic rod (5) Horizontal slide rail (6) Longitudinal slide rail (7) Stirring motor (9) Conveying pump (10) Horizontal lead screw (22) Horizontal sliding block (23) Nozzle bracket (24) Horizontal motor (25) Longitudinal sliding block (26) Longitudinal motor (28)
