Automatic Powder Resistivity and Compaction Density Meter
Function description:
Automatic pressure measurement,
Real-time measurement of the relationship between resistivity and compaction density during compaction of powder, pressure and compaction density map,
Automatically analyze the rebound deformation of the sample after constant pressure and pressure relief, and the resistivity and conductivity change spectrum during elastic deformation.
The height of the self-reading sample is measured to 0.001 mm;
Two control modes: touch screen and PC software;
Integrated control system, reporting function;
Automatic operation, the instrument has self-safety protection and abnormal alarm function.
Reference standard:
1. Compaction density measurement reference:
GBT 24533-2009 lithium ion battery graphite anode material;
GB/T 24533-2019 Lithium-ion battery graphite anode material
Appendix L: Test Method for Compaction Density of Powder
2. Four-probe tester refers to GB/T 1551, GB/T1552-1995, ASTM F84 US A.S.T.M standard.
3. Four-probe method powder test refers to the four-probe method for the arbitration method in the determination method of powder conductivity in GBT 30835-2014 "Carbon composite lithium iron phosphate cathode material for lithium ion battery".
Scope of application
1. Measurement of electrical resistivity of carbon composite lithium iron phosphate cathode material for lithium ion battery;
2. For analysis and detection of semiconductor powder materials that require four-probe measurements;
3. For the measurement of resistivity of graphite powder materials;
4. Applied to enterprise quality testing; R & D department, colleges and universities; research institutes; and quality testing institutions.
working principle:
During the compression of the external force, as the powder moves and deforms, the voids are filled, and the contact area between the particles increases, which creates an attractive force between the atoms and strengthens the mechanical wedge interaction between the particles, thereby forming a density and strength compact
In the process of forming the compact, the change process of resistance, resistivity and conductivity is measured in real time until it is stable.
