Study on Influence of Thermal Stability Test on Performance of Plastic Impeller Used in Coal Mine Auxiliary Fan
JU Guanggang
Abstract：In order to ensure the safe and reliable use of the plastic impeller in coal mines, thermal stability test of the plastic impeller used in coal mine auxiliary fan was carried out according to relevant standards, and the change of the flame-retarded ability, the antistatic property, the shock resistance, the tensile strength and so on of the plastic impeller before and after its test was analyzed and summarized. The test results showed that before and after the thermal stability test of the plastic impeller, its flame-retarded ability had no obvious change, the antistatic property was improved obviously and increased by 100 times; the shock resistance had also no obvious change and the tensile strength decreased significantly. The research results can provide scientific basis for the formulation and revision of relevant standards.
