Hangzhou plastic low temperature impact embrittlement tester_ Ningbo Plastic Impact embrittlement temperature teste

  Hangzhou plastic low temperature impact embrittlement tester_ Ningbo Plastic Impact embrittlement temperature tester is designed according to gb1682 national standard, and all technical indexes meet the requirements of national standards such as Hg 2-162-1965 plastic low temperature impact compression test method and gb5470-2008 (equivalent to iso974-80) plastic impact embrittlement temperature test method
In the original design of the instrument, the cold well agitator is added to make the temperature around the container more uniform, reduce the temperature faster, save time and reduce energy consumption
The brittleness temperature and low temperature properties of vulcanized rubber with different rubber materials or different formulations can be measured
Therefore, it is indispensable in scientific research, quality inspection of materials and products, control of production process and so on
Product introduction: this instrument is used to measure the maximum temperature when the vulcanized rubber sample is damaged by impact under the specified conditions, that is, the brittleness temperature
It can make comparative identification on the service performance of plastics and other elastic materials under low temperature conditions
The brittleness temperature and low temperature properties of vulcanized rubber with different rubber materials or different formulations can be measured

Hangzhou plastic low temperature impact embrittlement tester_ Application method of Ningbo Plastic Impact embrittlement temperature tester
1
The distance between the back of the instrument and the wall shall not be less than 0
5m, which is conducive to the ventilation of the refrigeration compressor unit

2
Inject industrial alcohol into the cold bath
The liquid level of alcohol should be less than 20mm from the cold notch, and it is better to immerse the fixture

3
Please note that after the instrument is powered on, the cold bath temperature is automatically controlled by the temperature controller, and the cold bath temperature begins to drop
During the cooling process, the impact hammer should be raised to leave the working medium, so as to avoid the impact hammer taking away the cooling capacity

4
Operation method of impact hammer:
1)
When the handle rotates counterclockwise, the impact hammer rises
Pay attention to the rising speed

2)
When the impact hammer drops, the handle rotates clockwise
Note that it should rotate quickly to reduce the resistance of the lifting rack when the impact hammer falls
After each impact, the hammer shall be lifted away from the working medium

5
Operation method of temperature control:
When the temperature control needs to be reset, you can press the set key
When so appears in the set temperature indication window, you can set it
Press the shift key to select the setting position, and then set the number as required
Press the plus or minus key
After setting, press the set key to enter the automatic temperature control state

6
The test operation method of the sample shall be in accordance with gb89488949-88 (artificial leather) test method

7
The refrigeration compressor is not allowed to start frequently
After shutdown, it can be started only after the cold bath temperature returns to + 10 ℃
