| （1） 表面粗化，增加附着力。用角磨机打磨，增加基材表面粗糙度，使其粗糙度达到标准的Sa2.5级。 (1) surface coarsening to increase adhesion. The surface roughness of the substrate is increased by grinding with an angular grinding machine, so that the roughness reaches the standard Sa2.5 grade. （2） 管壁挂钢丝网，抵御内应力，在不锈钢上表面焊接钢丝网，并严格控制丝网的平整度。 (2) The steel wire mesh is hung on the pipe wall to resist internal stress, and the steel wire mesh is welded on the surface of stainless steel, and the smoothness of the wire mesh is strictly controlled. （3） 涂刷BPO不锈钢底涂，增加附着力。焊接丝网完成后，在不锈钢基体表面上刷乙烯基脂树脂不锈钢底涂。 (3) brush BPO stainless steel undercoat to increase adhesion. After welding, the stainless steel substrate is brushed with vinyl ester resin and stainless steel undercoat. （4） 整体涂覆玻璃片胶泥。涂抹玻璃片胶泥2~3遍，将基体及丝网完全覆盖，对焊接拐角处以及及焊接部位进行特殊处理，即用玻璃鳞片胶泥做成圆角过渡。 (4) the whole glass is coated with cement. Spread the glass flake cement 2 to 3 times, completely cover the matrix and wire mesh, and make a special treatment on the welding corner and the welding part, that is, make a round transition with glass flake cement. （5） 用玻璃钢做层面，增强防腐层的整体性。用玻璃布和树脂做到“三油五布”防护层。 (5) use glass fiber reinforced plastics to make the surface to enhance the integrity of the anticorrosive coating. Use glass cloth and resin to achieve "three oil and five cloth" protective layer. （6） 严格施工工艺质量 (6) strict construction technology quality |
