Impact resistance test: Choose the push-out tube to be tested with a length of 1,000 mm, insert the two ends into the connecting head of the test equipment respectively, and use a pressure pump that produces alternating load liquid to impact the push-out tube with hydraulic oil.1.9. Generally this value is between 0. The ideal all-directional strength performance is P=1, that PTFE Fiberglass Fabric is, the longitudinal and transverse strengths are the same (P=transverse strength/longitudinal strength, T=transverse elongation/longitudinal elongation).
Take it out after heat preservation for 2 hours, tighten it again, cool to room temperature, take it out, prepare the template samples for stretching in the transverse direction and the longitudinal direction respectively, and then stretch on the stretching machine, and note the stretching Strength and elongation. In order to get better flatness, you can use the method of high-temperature shaping, put the expanded push-out tube in the splint for fixing, and then put it in an oven with a constant temperature of 100°C for heating. Under the same conditions, the larger the value, the better the performance of the material, and the same is true for the T value.
Do each sample 5 times and take the average value. At the same time, record the number of impacts and the magnitude of the alternating load used until the dispersed push-out tube ruptures. Divide into two sections, split longitudinally, and expand the push tube into a plane. Take a section of dispersed push-out tube, preferably with a larger diameter. Do it 10 times continuously and get the average value, which is the value of the impact resistance of this kind of dispersed push tube.
Generally speaking, the longitudinal tensile strength of most Ah E push tubes is greater than the transverse tensile strength, and the longitudinal elongation is greater than the transverse elongation. This value also reflects some properties of the material itself. Isotropic test: This test tests the consistency of the longitudinal and transverse performance of the PTFE tube.mdash; 0. This is just an ideal state
