The determination of the hydrostatic pressure resistance of the fabric is one of the most important indicators for assessing the waterproofness of textiles. The fabric hydrostatic pressure resistance tester is a testing instrument. Textile testing equipment, welcome customers who need to inquire in time. Waterproof performance is measured by measuring the height difference of static pressure maintained by the test sample before water ingress. One side of the test sample is clamped tightly with a clamp and the other side is exposed to the water pressure which increases at a constant rate The height of the water column required for penetration (shown according to the indicator paper) is the water resistance of the sample under the test conditions, and a hydrostatic pressure tester for textiles is designed accordingly.
The fabric hydrostatic pressure tester wordt used to measure the static resistance of waterproof fabrics Water pressure performance, suitable for compact fabrics, such as canvas, tarpaulin, tarpaulin, tent cloth, rainproof clothing cloth, etc. It is also suitable for determining the hydrostatic pressure resistance of high-efficiency air filter paper.
Test standard:
GB 4744 Measurement method for waterproofness of textile fabrics - hydrostatic pressure test method
Test operation:
Cut the test substance into a sample of 100mm × 100mm, place the sample in the clamp, tighten and fix the clamp. Press the up button, the metal container with 700ml of water starts to rise at a constant speed driven by the motor, and the water pressure is increased on the sample in the fixture, and the water is measured by measuring the color change of the indicator observe paper covered on the filter paper sample through the plastic window of the penetration fixture. When the first ssignal appears indicating the color change of the paper (from blue to pink), then immediately read the height of the water level on the scale, expressed in Pa (mmH20), and press the up button again to see the rise of the water level to stop. metal holder. Record the readings as the test data for the water tightness of the filter paper.
Open the fixture, take out the sample and indicator paper, dry the loading window of the fixture with a soft cloth and check the water level in the fixture. Top up with water if necessary. Use another sample and indicator paper to put it back on the fixture and repeat the test steps above for the test.
