1The construction, inspection and acceptance of anti-corrosion projects for stainless steel and carbon steel storage tanks should be carried out in strict accordance with the requirements. After the surface of the anti-corrosion material has dried, the dry film thickness of the bottom layer, middle layer and surface paint film should be measured respectively. The dry film thickness of each layer and the total dry film thickness of the coating should meet the relevant requirements in these regulations.

       2, Check the number of coating passes and painting quality, and conduct visual inspection after the coating construction is completed. The main inspection contents of coating quality include: whether the coating has leakage, rust return, bubbles, bottom penetration, sagging, wrinkles, etc.; whether the coating is flat and smooth; whether the color is uniform; and5~10Use a magnifying glass of5%.

       3. When applying paint, use a wet film thickness gauge to measure the wet film thickness.

       4,treatStainless steel carbon steel storage tankAfter the anti-corrosion coating is completed and the paint film is dry, a thickness gauge should be used to measure the thickness of the coating.

       5, the equipment coating thickness is required to be uniform, and the acceptance standards are“90-10rule”,Right now90%The measured value must reach the specified dry film thickness, allowing10%The value is low, but it should be greater than“specified value90%”, otherwise the number of coating passes should be increased until qualified.

       6. For electrostatically conductive coatings, after the construction is completed and the paint film is dry, the resistivity of the coating must be measured with a paint resistivity tester. The surface resistivity of the coating electrical property test result should be less than109Ω, or the volume resistivity is less than108Ω.m, and the test results should be within the same order of magnitude.
