Problems solved by technology

[0002] At present, most of the domestically produced honeycomb ceramics use traditional cordierite honeycomb ceramic materials, which have extensive and cheap raw materials and low requirements for technical equipment, so they are widely used, but their firing temperature is high and energy loss is serious. In addition, alumina The regenerator of honeycomb ceramics is poor in high temperature resistance, and generally cracks and other phenomena will occur when it exceeds 1200 ° C, and the service life is short
Therefore, the heat resistance of cordierite raw materials has always been a subject of research by various domestic enterprises and honeycomb ceramic research institutes, but the current research cost is not ideal
