Tire reclaimed rubber as the most common kind of reclaimed rubber products, and sometimes may be used to make conductive media, then the tire reclaimed rubber breakdown voltage how high, the breakdown voltage level and what factors? First and Xiaobian together to see what is called tire reclaimed rubber breakdown voltage.
Breakdown voltage as the name suggests is the dielectric breakdown voltage. Dielectric in the strong enough electric field will lose its dielectric properties as a conductor, known as the dielectric breakdown, the corresponding voltage is called the breakdown voltage. Dielectric breakdown electric field strength is called breakdown field strength. Different dielectric at the same temperature, the breakdown field strength is different. When the distance between the capacitor medium and the bipolar plate d is constant, it is known from U1-U2 = Ed that the breakdown field strength determines the breakdown voltage. Breakdown field strength is also commonly referred to as dielectric dielectric strength.
Under normal circumstances, assuming the frequency of 50 Hz under the premise of tire reclaimed rubber breakdown voltage should be greater than 500V.
The breakdown voltage of tire reclaimed rubber is closely related with the impurities contained in reclaimed rubber. Generally, the conductive coefficient of reclaimed rubber of steel tire is much higher than the conductivity coefficient of reclaimed rubber of nylon tire. Therefore, when using reclaimed rubber as conductive medium, The key, according to the need to choose the right material tire reclaimed rubber products.
Breakdown voltage tire reclaimed rubber we can get through professional testing, breakdown voltage measurement principle: the reclaimed rubber tire samples applied AC voltage, you can continue to step up or step by step, until the tire reclaimed rubber test Like to be punctured and measured the voltage value, that is, the value of the tire reclaimed rubber breakdown voltage.
The tire reclaimed rubber sample for breakdown voltage test should meet the defects of smooth surface, no cracks, no bubbles, no edge burr and mechanical impurities, and try to eliminate the internal stress generated when the reclaimed rubber sample is prepared and the temperature Effect of Humidity on Breakdown Voltage Measurement Structure: The test sample is kept at 23 ± 2 ℃ and the relative humidity is controlled at 50 ± 5% by using the organic solvent silk cloth stained with no corrosion to the sample.
Take Hongyun Ultrafine Recycled Gum as an example, we select more than 80 mesh rubber powder of high quality 900 discarded tire as raw material, undergo strict magnetic separation, desulfurization, filtration, refining and shaping, high fineness of products, no metal, Produced fine ionic tire reclaimed rubber uniform and tidy, after testing, 20000 voltage 800v test without breakdown.
