Ask geotextile factory in the use of geotextile aperture detector detection method which?
Hello, geotextile detection method in GB / T and GB / T geotextile aperture in the introduction, you can look at these two standards. The first is geotextile pore size detection wet sieve method, the second is geotextile aperture detection dry sieve method. As the name suggests the first of these two methods is the participation of water, the other is basically the same, are placed in a single layer of geotextile standard small particles, through the vibration to detect the size of the leakage of particles to determine the geotextile pore size size. The difference is that the first standard in the need for continuous water on the particles, so the calculation method are also different. Specific detailed distinctions You can search these two criteria separately.
