I. Characteristics and uses of low temperature brittleness tester for rubber and plastics:
Various technical indicators of this instrument meet the requirements of national standards such as gb / t 1682-1994 "Vulcanized rubber low temperature brittleness (single sample method)". Measure the high temperature of vulcanized rubber when the sample is damaged under impact under specified conditions, that is, the brittleness temperature. It can compare the performance of plastics and other elastic materials under low temperature conditions. It can determine the pros and cons of brittleness temperature and low temperature performance of vulcanized rubber with different rubber materials or different formulations. Therefore, it is indispensable both in the quality inspection of scientific research materials and their products, and in the control of the production process. In the original design of the instrument, a cold well agitator was added to make the temperature around the container more uniform, lower the temperature faster, save time and reduce energy consumption.
Structure principle of low temperature brittleness tester for rubber and plastic
3.1 Lifting gripper
The lifting clamp consists of a cylinder with a clamp and a cylinder block.
The distance from the impacted part of the sample to the lower end of the holder is 11.0 ± 0.5mm
3.2 Impact device
The impact device consists of an impactor and an impact cylinder.
Impactor head shape and size. The weight of the impactor is 200 ± 20g, and its working stroke is 40 ± 1mm. In the reset state of the impact cylinder, the distance from the end of the impactor to the sample is 25 ± 1mm.
