ZTT-980 silicon core tube cold bending radius Tester is a silicon core tube cold bending radius Tester in Beijing Tiandi Xinghuo Technology Development Co., Ltd. The bending radius test method was developed. The equipment is simple and intuitive, and it is a satisfactory equipment for production and quality supervision and inspection departments.
1. Application: It is suitable for measuring the bending resistance of silicon core tubes at low temperatures. It can meet the high-density polyethylene silicon core plastic pipes of underground communication pipelines with different diameters from 32 to 63mm.
2. Other testing equipment: a low-temperature box whose temperature can be controlled at -20°C±2°C.
3. Samples: Take 3 silicon core tubes with a length of 1.5 meters (2 meters when the outer diameter is greater than 40mm) as samples for the bending performance test of the product. Before the test, the samples should be placed at a temperature of -20°C ± 2°C Keep it down for 2h.
4. Judgment rules: After the sample has passed the bending test, there should be no cracks, cracks or obvious stress whitening.
