Ⅲ、酸罐生漆防腐层的施工一、金属罐的技术要求1.金属罐结构上要牢固,要有一定的刚度。否则漆膜会因结构的损坏或变形而破坏。2.涂漆表面应平整,不得有大于2毫米的凸起或凹缝,有时应以砂轮等消除,以保证漆膜厚薄均匀、平滑。为此涂漆表面上的焊缝也应为对接焊缝,并应打磨平整。圆筒与封头对接处,如钢板厚度不同时,应以涂漆面找平(见图8)。 III. Construction of acid tank lacquer anti-corrosion layer 1. Technical requirements of metal tank 1. The metal tank must have a firm structure and certain rigidity. Otherwise, the film may be damaged due to structural damage or deformation. 2. The painted surface should be flat and there must be no projections or notches larger than 2 mm, and sometimes it should be eliminated with a grinding wheel to ensure that the film thickness is uniform and smooth. For this purpose, the weld on the painted surface should also be a butt weld and should be polished smooth. When the thickness of the steel plate is different at the butt joint between the cylinder and the head, the paint surface should be leveled (see Figure 8).
