เครื่องวัดความดันอุทกสถิตและค่าสัมประสิทธิ์การซึมผ่านของ (Geomembrane)
-
Used for testing nonwoven geotextiles or other materials as the base material, with polyethylene, polyvinyl chloride and other films as the film production of nonwoven composite geotextiles (one cloth one film, two cloth one film), under the specified hydraulic pressure difference, test sample’s hydrostatic pressure and permeability coefficient performance.
Standards GB/T17642, GB/T19979, JTG E50-2006
Test principle
-
When the pressure head on both sides of the sample reaches a certain value, the sample is broken. Increase the hydraulic pressure difference on both sides step by step, and keep it for a certain time. When the seepage flow increases rapidly, it indicates that the sample is damaged, that is, the hydrostatic pressure value is obtained.The machine can contain two functions, namely, the determination of hydrostatic pressure and permeability coefficient.
Features
-
high-definition LCD display panel, digital display, no manual reading error.
- The test plate adopts SUS304 stainless steel plate, which is corrosion resistant, easy to clean and elegant in appearance.
- Multi-purpose of one machine, that is, both hydrostatic test and permeability coefficient test are satisfied at the same time.
- Body surface treatment: dupont powder, electrostatic painting process, after high temperature 200℃ curing for a long time.
