Brief introduction: ISO1520 based on international standards and national standards for design and production of QBJ GB9753-88 type paint varnish coating cupping testing machine is suitable for the evaluation and related products of coating (single or supporting coating) under the standard of experimental method, a pressure test, gradually after deformation, the cracking resistance of the coating or resistance to the performance of the separation of the metal material, evaluation of coating by or through. Can also gradually increase the sag depth, to determine coating was cracking or start from the minimum depth of the substrate. Technical indicators: 1, sag diameter: 20 mm 2, pressure trap maximum depth: 10 mm 3 and in accuracy of pressure: 0.05 mm 4, digital display degree value: 0.01 mm 5, the maximum sag force: 1000 n 6 specimens, specifications: 70 mm * 70 mm * 0.03 mm to 1.25 mm
