TH-7040 Rubber Brittleness Temperature Tester Introduction: TH-7040 single sample rubber brittleness temperature measuring instrument is to measure the high temperature of the vui when the vulcanized rubber is damaged by the impact under the specified conditions, which is the brittle temperature, which can be used for non-hard plastic and other elastic materials under low temperature conditions. The performance of the use for comparative identification. The brittle temperature and low temperature properties of vulcanized rubbers of different rubber materials or different formulations can be determined. Therefore, it is indispensable in the quality inspection of scientific research materials and their products, and the control of production processes. The instrument is designed according to the national standard GB/T1682-94, and the technical indicators meet the requirements of national standards. Features: Lifting clamp The lift gripper consists of a cylinder with a gripper and a cylinder block. The distance from the impact portion of the sample to the lower end of the holder was 11.0 ± 0.5 mm. 2. Impact device The impact device consists of an impactor and an impact cylinder. 3. Impactor The shape and dimensions of the impactor head are shown in Figure 2. The impactor has a weight of 200 ± 20 g and a working stroke of 40 ± 1 mm. In the reset state of the impact cylinder, the distance from the end of the impactor to the sample is 25 ± 1 mm. 4. Freezing medium Industrial ethanol is usually used. 5. The measuring instrument uses semiconductor refrigeration. Technical Parameters Test temperature: -70 ° C - 0 ° C (semiconductor refrigeration) Impact speed: 2m / s ± 0.2m / s After the constant temperature, the temperature fluctuation during the test within 3 min: <±0.5 °C Distance from the center of the impactor to the lower end of the holder: 11±0.5mm Dimensions: 720 × 700 × 1380mm Power: 1100W Cold well volume: 700ml
