News Abstract: the welding seam on the steel surface must reach the anti-corrosion of the sewage pool, and the surface shall be free of edges and corners, smooth and free of weld bead. If the primer is applied on both sides of the weld, the primer shall not be applied to the surface of the weld, and the primer shall be applied to the surface of the weld to avoid a transition of 2mm after the primer is applied to the surface of the weld.
Anti corrosion of sewage tank Construction points for attention: The welding seam on the steel surface must reach the anti-corrosion of the sewage pool, and the surface shall be smooth and free of weld bead. If the welding seam is higher than 2mm, the primer and talcum powder shall be used to prepare putty with appropriate viscosity. After the primer surface is dry, it shall be applied on both sides of the weld and scraped to make the primer surface become a transition surface to avoid vacuum when wrapping glass cloth. During construction, attention shall be paid to the changes of weather and temperature, and the construction shall not be carried out in rainy, foggy, snowy days or when the relative humidity is greater than 80%. The thickness of anti-corrosion glass cloth in sewage pool The degreased non alkali or medium alkali glass cloth with the specifications of 0.1 mm or 0.12 mm, longitude and latitude density of 12 × 10 pieces / C m2or 12 × 12 pieces / C m2shall be dried before use.
