Low Temperature Brittleness Tester Rubber Testing Instruments High Performance
low temperature brittleness tester
Single sample method rubber low temperature impact tester, rubber
low temperature brittleness tester, low temperature brittleness
tester technical parameters:
1. Test temperature and time: -70 degrees (normally more than 1
hour)
2. Impact speed: 2m/s±0.2m/s
3. After the constant temperature, the temperature fluctuation
during the test within 3 minutes: <±0.5°C fluctuation is small,
and the temperature control is more accurate.
4. Distance from the center of the impactor to the lower end of the
holder: 11±0.5mm
5, size: 900 × 500 × 850 studio size: 240 × 170 × 150 (length ×
width × height)
6, power: 800W
The low-temperature impact tester is a temperature at which the sample is damaged by impact under the specified conditions, that is, the brittleness temperature, and the performance of the plastic and other elastic materials under low temperature conditions can be comparatively identified. It can measure the brittleness temperature and low temperature performance of vulcanized rubber of different rubber materials or different formulations. 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 GB1682 national standard. The technical indicators meet the requirements of HG 2-162-1965 plastic low temperature impact compression test method and GB5470-2008 plastic impact embrittlement temperature test method.

specification
The sample has a length of 25.0 ± 0.5 mm, a width of 6.0 ± 0.5 mm,
and a thickness of 2.0 ± 0.3 mm. 5.2 requirements
The surface of the sample should be smooth and free of foreign
matter and damage. The finished product should be ground to the
appropriate size.

tester structure principle:
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 size of the impactor head are shown as objects. The
impactor has a weight of 200 ± 20 g and a working stroke of 40 ± 1
mm. When the impact cylinder is in the reset state, the distance
from the end of the impactor to the sample is 25±1 mm.
4. Freezing medium: industrial ethanol
5. The measuring instrument is directly cooled by a compressor. It
is not necessary to cool the circulating water.
