Product Description
Application of Equipment
The low-temperature brittleness testing machine is to determine the lowest temperature at which rubber materials do not exhibit brittle failure or the temperature at which half of the test pieces used in a test fail when impacted under specified conditions.Therefore, it is indispensable in the quality inspection of scientific research materials and products, and the control of the production process.
This equipment adopts cascade compressor refrigeration technology, uses the principle of heat balance and cyclic stirring, to achieve automatic uniform cooling and constant temperature of the specimen, and can fully meet the various temperature control indicators specified in the national standard GB/T229.
Applicable Standards
1. ISO812 Rubber, vulcanized or thermoplastic - Determination of low-temperature brittleness
2. GB/T 15256 Rubber, vulcanized or thermoplastic - Determination of low-temperature brittleness
3. JIS-K-6261-2006 Rubber, vulcanized or thermoplastic - Determination of low temperature properties
4. ASTM D2137 Rubber property-Brittleness point of flexible polymers and coated fabrics
Main Technical Parameters
1. Temperature control range: -70℃
2. Cooling speed: about 2 hours. Note: Use the environment at room temperature (23-25℃). Keep the compressor's cooling effect during work, and all side doors can be opened.
3. After the constant temperature, the temperature fluctuation within 3min of the test: <±0.5℃
4. Cooling medium: ethanol or other non-freezing liquid
5. Stirring motor: 10W
6. Working power supply: Single phase 220V~240V, 50Hz, 2KW
