Iron sulfide120#

Iron sulfide has excellent high-temperature stability, making it an important filler for high-end grinding wheels due to chemical reactions. However, the key to chemical reactions lies in its purity. Another key factor is the composition of impurities. A large amount of impurities may be harmful to grinding, but instead increase the wear of the grinding wheel and reduce its working life. The reaction of absorbing oxygen occurs between 400 and 475 degrees, reducing the oxidation of resin and the oxidation burn on the workpiece, thereby extending the high-temperature working life of the grinding wheel. The temperature range of 400 to 475 degrees is a very easy limit for grinding wheel operation. The above reaction creates an anaerobic and oxygen deficient environment at the micro level, thereby improving the high-temperature performance of the grinding wheel. The decomposition reaction of absorbing heat at 650 degrees occurs, reducing the working temperature of the grinding wheel
