Problems solved by technology

In addition, the existing test is generally the relationship curve between the percentage of conductive foam compression and the resistance and pressure, such as the curves generated by the corresponding resistance and pressure values ​​when the conductive foam is compressed by 10%, 20% and 70%, respectively. The data collected by the method is relatively small, and the test results cannot be displayed accurately

Abstract

The invention discloses a method for testing conductive foam, comprising: step 1, providing conductive foam to be tested, and loading the conductive foam on a test platform; step 2, providing a test host, a multimeter and a torque sensor, and inputting Test parameters, the test host calculates the step times of the servo motor according to the test parameters; step 3, the test host drives the servo motor to compress the conductive foam according to the input test parameters and step times, and the multimeter measures the surface resistance of the conductive foam in real time and transmits For the test host, the torque sensor measures the pressure value of the conductive foam in real time and transmits it to the test host; step 4, the test host automatically generates an analysis curve and analysis results according to the measured surface resistance value and pressure value, and displays the analysis curve and analysis results. result. The invention tests the pressure value and the resistance value on the same device at the same time, and automatically generates a test curve, the test operation is simple, convenient and quick, and the display interface is simple and clear.

Description

technical field [0001] The invention relates to the technical field of conductive foam testing, in particular to a testing method for conductive foam. Background technique [0002] Conductive foam is made of polyethylene (PE) and carbon black as the main raw materials, adding dozens of additives with excellent performance. Perfect combination with polyethylene to form polymer conductive foam. Conductive foam is made by extruding polyethylene or modified polyethylene with conductive filler and antistatic agent, and then irradiated and foamed at high temperature to make conductive plastic. Its surface resistance and volume resistance are 10 to the 3-9 power, Permanent conductivity, smooth surface, environmental protection, widely used in many fields such as ESD. In addition, conductive foam has good electrical conductivity and long-lasting ability to eliminate static electricity, no pollution, no corrosion, no dust, peeling and desquamation, moisture-proof, shock-proof, heat...
