The bentonite waterproof blanket permeability tester measures the permeability coefficient of these impermeable mats under set pressure and time. Under a certain pressure difference, the mat allows minor seepage. By gauging the seepage flow and sample thickness within a specified time under given pressure, the permeability coefficient can be calculated.
Application:
Used to determine the permeability coefficient of bentonite waterproof blanket under specified pressure and time conditions. The bentonite waterproof blanket will produce small seepage under a certain pressure difference, and the permeability coefficient can be calculated by measuring the seepage flow and the thickness of the sample within a certain time under the specified hydraulic pressure difference.
Standard:
SL/T :Specification for test and measurement of geosynthetics
JG/T 193- Appendix A-2006:Appendix A: Test method for water permeability of sodium bentonite geosynthetic clay liner (equivalent to ASTM D5084-1990)
GB/T 35470- Appendix B-2017:Appendix B: [Specific test method or additional requirements for rail transportation applications]
JC/T 2054- Appendix A-2020:Appendix A: [Specific test method or additional requirements for natural sodium bentonite impermeable liner]
ASTM D5887-1999:Standard Test Method for Measurement of Index Flux Through Saturated Geosynthetic Clay Liner Specimens Using a Flexible Wall Permeameter
Features:
Using 1+2 mode, it can provide a single station machine and a 2 station auxiliary machine;
The table is made of stainless steel, clean appearance, good water resistance, no rust;
Test through pressure loading, no need to connect to electricity, safe and reliable;
Adopt imported high-precision pressure regulator, the pressure regulation is accurate and stable, to ensure the experimental requirements;
The loading circuit design is reasonable, and the valve switch adjustment is simple;
The measurement accuracy was improved to 0.05m1.
The integrated vacuum device makes it easier to vacuum during sample preparation and testing;
Add negative pressure degassing device, so that the water entering the sample is degassing water, the test result is more accurate; :
The test chamber can be moved to make the operation more flexible;
The main use of two-position valve, instrument operation is simpler;
The automatic test interface is reserved, which can be more convenient to obtain pressure reading and automatic measurement by adding an automatic test device.
