Materials according to the surface resistivity classification
Conductor: the surface resistivity of the material is very small and easy to conduct current, under the action of the external electric field, there are a large number of freely movable charged particles in the conductor for directional movement, can form a significant current. Common conductors are metals and carbon compounds (graphite, carbon black, carbon fiber, carbon nanotubes, etc.)
Antistatic: Static electricity declines at a slow rate of 0.01 seconds to several seconds, preventing electrical breakdown, electrical sparks, or electrical adsorption.
Static Dissipation: Decay rate in milliseconds (0.001), faster dissipation or decay rate than anti-static materials.
Conductive: Decay rates in nanoseconds provide a path to ground and release a stronger charge.
EMI/EFI Shielding: absorbs or reflects electromagnetic energy and shields against sources of interference. Usually measured by volume resistivity.
Surface resistivity test method
HONY Plastic usually uses a Parallel Probe Surface Resistivity Meter to test the surface resistivity of plastic materials.
The Parallel Probe ResistivityMethod is a fast and convenient way to measure the surface resistivity of flat, uniform materials in accordance with the EOS/ESD-S11.11-1993 standard.
Requirements of the object to be tested: the surface is flat and the size width is more than 60mm.
The test steps are as follows:
1. Place the tested sample on the insulating mat.
2. Place the tester on the surface of the tested sample.
3. Set the voltage switch to the desired voltage position (10 volts or 100 volts). (Some simpler testers do not have a voltage switch.)
4. Press the measurement button continuously with a pressure of about 2.5 kg to read the surface resistivity (depending on the accuracy of the tester, some can only read values of the order of 10), temperature, and relative humidity (depending on the accuracy of the tester, some cannot be read), and the entire measurement process will take about fifteen seconds.
For larger or smaller sizes where parallel probes cannot be used, testing can also be done by using different forms of electrodes such as pincers, concentric rings, weights, and two points.
HONY Plastic R & D and production of conductive anti-static electromagnetic shielding plastic conductive fillers include: carbon fiber, carbon black, carbon nanotubes, graphite, polymer long-lasting antistatic masterbatch, low molecular antistatic agent, stainless steel fibers, iron powder and so on.
