Product Description

ISO1520 Cupping Tester Tests Equipment Device GA-6059
Scope Of Application
ISO1520 based on international standard and national standard GB9753 cup drawing design and manufacture of QBJ type coating machine is suitable for the evaluation of paint varnish and coating of related products (single-layer coating) or supporting system under the experiment method of standard, sag experiment was carried out, and make it gradually after deformation, the cracking resistance of the coating or resistance to the performance of the separation of the metal substrate, Evaluate coating pass or not pass. The depth of the indentation can also be gradually increased to determine the minimum depth at which the coating has just begun to crack or to detach from the substrate.

1Preparation of the test film
(1) The test piece is square, and its size is 70mm*70mm*0.3mm~1.25mm
(2) The material of the test piece should be polished steel plate, and meet the requirements of GB9271, and the test piece should be flat without deformation.
(3) Prepare the coating according to the standard requirements, dry it and measure its thickness. At a temperature of 23±2°C and relative humidity of 50±5%, the test was carried out after at least 16 hours of state adjustment.

Operation method
(1) single coated plate test: -- automatic zero
Turn the hand wheel of the testing machine toward the downward direction (clockwise) to the end, loosen the upper part of the testing machine test piece pressing device, the metal surface of the single coating test plate down, the coating layer is inserted into the crack on the upper part of the testing machine, and the punch is aligned with the central axis of the test piece, fastening the pressing device. Press the red zero button of the instrument and the monitor will show zero. Turn the handwheel in the upward direction (counterclockwise direction) at a speed of 0.2±0.1mm/s (i.e., a turn of 2~3 seconds). When the punch hits the metal surface of the test plate, the display automatically shows zero, and the instrument lights red. Then continue to rotate the handwheel, the display reading is rising height, that is, the depth of depression, irreversible, otherwise the reading is not allowed.
(2) double-sided coated plate test, - manual zero
Turn the hand wheel of the testing machine in the downward direction (clockwise) to the end, loosen the upper test piece pressing device of the testing machine, insert the random zero adjusting steel plate into the crack of the upper part of the testing machine, and tighten the pressing device. Press the red button on the meter to make the monitor display zero. Turn the HANDwheel in the rising direction (counterclockwise direction). When the instrument lights red, that is, when the display is zero, stop turning the handwheel. Release the pressing device, then manually clear the zero (press the red button of the instrument), turn the handwheel in the upward direction at the speed of 0.2±0.1mm/s, and the indicator reading is the upward height, that is, the depth of the depression.
(3) With corrected visual acuity or 10x magnification, check the coating on the test piece for cracking or separation from the substrate.
(4) The above procedure shall be carried out on two separate test pieces. If the results are different, additional tests shall be conducted until the results of the two test pieces are consistent. If there are cracks in the substrate, the experimental results are invalid.

Determine the minimum degree of damage caused
(1) When the coating on the test piece cracks for the first time, or the coating separates from the substrate, the punch stops moving (the number on the display is the advance depth). The above tests shall be repeated on the same substrate to verify the results until they are consistent.
