Parameters and test methods of digital fabric burst strength tester

Product Name: Digital Fabric Bursting Strength Tester, Textile Bursting Tester Model: G229B Purpose: This machine can be used to detect the bursting strength and height of woven, knitted, non-woven fabric, paper or board. The instrument uses hydraulic blasting method. The rubber film of a specific area is then applied to the sample to force the fabric to burst. Principle: The digital burst strength tester can detect the burst strength of knitted fabrics, apply oil pressure on a specific area of u200bu200bthe rubber membrane, and then force the fabric to burst. This instrument is equipped with a pressure display, peak holding record and peak upper limit setting, replaceable rubber diaphragm, and manual clamping device. Compliance with standards: ISO?? 13938-1/3689/3303/2758??, ?ERT 80-4-20?? ASTM? D3786 BS 3137/3424(PT6)/4768, GB/T 7742.1 technical parameters: 1, Maximum power: 6000kPa2, test area: 80mm diameter Product features: ①, full test area support, suitable for different standard requirements, meet GB standard maximum 100cm2 test area; ②, support PC terminal online communication, statistical analysis of the results, printable Test report; ③, pneumatic clamp, the clamping force is firm and uniform, and can be applied to the clamping of various materials in all directions; ④, the test results are rich in expression, which can display such as: bursting strength, bursting strength, diaphragm pressure, swelling Bursting height and bursting time; it is convenient for quality control personnel to fully understand the bursting performance of the sample. Test procedure Put all the samples under the standard atmospheric conditions required by the standard to adjust the humidity and balance, and prepare the test samples of the required size. ① Manual test: 1. Installation of the test sample Put the moisture-conditioned sample in the clamp and pull the sample tightly along the plane to avoid wrinkles. Place the test cup on top of the test sample. 2. Rotate the handwheel clockwise at a speed of 120 rpm until the sample breaks. Stop rotating the hand wheel at the moment the sample ruptures. After the sample ruptures, quickly loosen the clamp ring on the sample. Rotate the handle counterclockwise to the starting point to relax the film. Record the pressure required to expand the film and record the total pressure required for the sample to rupture . Note If the pressure on the dial shows that the pressure has stopped rising, but the sample has not broken yet, push the lever to remove the pressure. Record the elongation of the sample that exceeds the measurement limit of the testing machine. ②Automatic test: Put the humidity-conditioned sample in the clamp and pull the sample tightly along the plane to avoid wrinkles. Place the test cup above the test sample and move the operating handle to the left to expand the film. When the film expands, hold the latch on the lower or right side of the operating lever. When the sample breaks, try to rotate the latch to return the operating lever to the middle position. Record the total pressure required to rupture the sample. After the sample ruptures, quickly loosen the clamp ring on the sample, swing the latch to its normal position, remove the pressure on the membrane, push the operating lever to the right, and record the pressure required to expand the membrane.
