PRODUCT

ZY-1006 Rubber Low Temperature Brittleness Testing Machine (Single Sample)
The ZY-1006 rubber-plastic low-temperature brittleness testing machine is used to determine the highest temperature when the sample is damaged by impact under specified conditions, that is, the brittle temperature. It can be used for comparative evaluation of the performance of plastics and other elastic materials under low temperature conditions. . It can measure the brittleness temperature and low temperature performance of different rubber materials or different formulations of vulcanized rubber.

ZY-1006 Plastic Low Temperature Brittleness Testing Machine
1. Features and uses: The ZY-1006 rubber-plastic low-temperature brittleness testing machine is to measure the temperature at which the sample is damaged by impact under specified conditions, which is the brittle temperature. It can be used for comparative evaluation of the performance of plastics and other elastic materials under low-temperature conditions. It can measure the brittleness temperature and low temperature performance of different rubber materials or different formulations of vulcanized rubber. Therefore, it is indispensable in the quality inspection of scientific research materials and products, and the control of the production process. This instrument is designed according to the GB/T 5470-2008 standard. It is equipped with a B-type fixture and impact head that can test multiple samples at the same time. This test fixture can hold 5 samples for simultaneous testing. 2. Technical parameters 1. Test temperature and time: -70 degrees (normally more than 1 hour), the cooling time is short, no water cooling is needed, and it is more environmentally friendly. 2. Cooling speed: 0℃ ~ -30℃ 1.2℃/min -30℃ ~ -40℃ 1℃/min -40℃ ~ -70℃ 0.7℃/min 3. Impact speed: 2m/s±0.2m/s 4. After the constant temperature, the temperature fluctuation is less than ±0.5℃, and the temperature control is more accurate. 5. The distance from the midpoint of the impactor to the lower end of the holder: 8±0.5mm 6. Dimensions: 900×505×950mm (length×height×width) 7. Effective space of studio: 160×140×100mm (length×height×width) 8. Power: 2000W Three, structure principle 1 Lifting gripper The lifting gripper is composed of a cylinder with a gripper and a cylinder block. The distance from the impacted part of the sample to the lower end of the holder is 8.0±0.5mm. 2 Impact device The impact device is composed of an impactor and an impact cylinder. 3 impactor The weight of the impactor is 200±20g, and its working stroke is 40±1mm. When the impact cylinder is in the reset state, the distance from the end of the impactor to the sample is 25±1mm. 4 Freezing medium: industrial ethanol 5 This measuring instrument uses a compressor for direct cooling. It does not require cooling circulating water. Four, use method 1 Turn on the power, the temperature controller and timer display lights are on. 2 Inject the freezing medium (usually industrial ethanol) into the cold well. The injection amount should ensure that the holder sample can be immersed below 25mm of the medium liquid level. 3 Clamp the sample vertically on the holder. The clamp should not be too tight or too loose to prevent the specimen from deforming or falling off. 4 After reaching the test temperature, press the start button, and the testing machine will work automatically (press the holder to start freezing the sample, and at the same time start the timing control switch or press the stopwatch to time, the sample freezing time is specified as 3min. The sample freezing period , The temperature fluctuation of the freezing medium shall not exceed ±1℃) 5 Take off the sample and check each sample to determine whether it is damaged. The cracks, cracks, or small holes that appear during the test, or separate into two pieces so that more fragments are defined as damage, when the sample is not broken At the time, bend the specimen 90° in the bending direction formed during the impact, and then inspect the specimen for cracks at the bend. 6 After the sample is impacted (each sample can only be impacted once), if damage occurs, the temperature should be increased by 10℃ to do a new set of tests, and a new sample should be used at each temperature until the sample is not damaged. If there is no damage to the sample, then the temperature is reduced to the highest temperature of damage that has been observed. Control the temperature increase or decrease at a temperature interval of 2°C until the temperature at which a set of samples is not damaged is measured, and this temperature is recorded as the brittle temperature. 5. Sample standard 1 Specification requirements: length 31.75±6.35mm, width 6.35±0.51mm, thickness 1.91±0.13mm 2 Requirements: The surface of the sample should be smooth, free of foreign impurities and damage. The finished product should be cut into corresponding size after grinding. Six, matters needing attention The cylinder pressure has been adjusted before leaving the factory and cannot be changed arbitrarily.
