Working Method Of Hydrostatic Pressure Tester - China

The hydrostatic pressure method refers to a test method for measuring the water permeability of fabrics under a certain water pressure.

It is applicable to all types of fabrics, including those that have been waterproofed.

The hydrostatic pressure method measures the waterproofness of fabrics, there are static pressure method and dynamic pressure method.

The static pressure method is to apply hydrostatic pressure on one side of the fabric to measure the amount of water produced under this hydrostatic pressure, the time of dripping, and the value of the hydrostatic pressure at a certain amount of water.

The hydrostatic pressure can be the height of the water column, or It can be pressure.

In the actual measurement, the water permeation per unit area and unit time (mL/cm2 - h) is measured.

For waterproof fabrics, measure the time required for water droplets to appear on the other side of the sample, or observe the number of water droplets on the other side after a certain period of time.

The water resistance of the fabric is related to the water resistance of the fiber, yarn and fabric structure.

The measured results are different from the water spray and rain on the surface of the fabric.

Specific operation: The sample is fixed on the test area of ​​the standard area, the air compressor adds 0-5bar air into a water tank filled with distilled water, and a certain pressure of water is applied to the sample.

It can be tested by dynamic or static two methods.

(1) Dynamic method: Determine the hydrostatic pressure resistance of the sample by testing the pressure when a fixed amount of water drops on the side of the sample that is not in contact with water at a certain pressure increase rate.

(2) Static method: Determine the hydrostatic pressure resistance of the material by testing the water seepage of the sample after maintaining the pressure for a certain period of time under a certain hydrostatic pressure.
