Problems solved by technology
In addition, due to frequent contact with acid and alkali solutions, the life of the conductive needle is very short, so precious metal materials have to be used, so the device has high cost, complex structure, and inconvenient maintenance.
In addition, the current acid-proof permeability tester generally can only test one sample at a time. In order to obtain the penetration time with small deviation of the sample, it is necessary to repeat multiple experiments when taking the average of the experimental results. , a longer experiment time is required

The invention relates to an acid-proof permeability tester and a detection method. The acid-proof permeability tester includes a test unit, a main control unit and a display control panel, wherein the main control unit is respectively connected with the test unit and the display control panel, and is used to It is used to receive the conduction signal of the test circuit of the test unit, and display the information of the conduction signal on the display control panel. The indenter of the acid-proof permeability tester of the present invention is made of ordinary stainless steel, and is fixed on the pressing plate with screws, which is convenient for replacement and low in cost. In addition, 6 test positions are set in the test unit of the present invention, and 6 samples can be tested at the same time, which greatly saves experiment time.
Description
technical field [0001] The invention relates to an acid-proof permeability tester and a detection method. Background technique [0002] The current anti-acid permeability tester utilizes conductivity method and automatic timing device to test the penetration time of acid-base chemical protective clothing of fabric samples. The sample is placed between the upper and lower plates, the conductive wire communicates with the upper plate, and at the same time contacts the upper surface of the sample. When penetration occurs, the circuit is turned on and the timing is stopped. At present, a conductive needle is usually used to apply a certain pressure through the vertical device to facilitate the conduction of the circuit. In addition, due to frequent contact with acid and alkali solutions, the life of the conductive needle is very short, so precious metal materials have to be used, so the device has high cost, complicated structure, and inconvenient maintenance. In addition, the...
