First, clean the leakage point of silicon nitride and use leak-stopping agent glue to repair the leakage point. To deal with the leak-stopping agent cement, quickly press the processed cement in the direction of the leakage. After a while, it will be done. After blocking the water, use polymer waterproof mortar to plaster the surface and maintain it for three days.
For silicon nitride cracks with serious water leakage, first drill drainage holes in the serious water leakage area to slow down leakage in other places, then block the drainage holes, and then plaster the surface with polymer waterproof mortar. The leakage of silicon nitride after construction is not entirely caused by the quality, but may also be caused by the laxity of the construction. The important thing is to find ways to resolve them promptly when they arise.
Silicon nitride powder is used in the mechanical industry to make high-speed turning tools, bearings, supports for heat treatment of metal parts, rotor engine scrapers, gas turbine guide vanes and turbine blades, etc. In the semiconductor, aviation, atomic energy and other industries, it is used to manufacture switching circuit substrates, film capacitors, electrical insulators that can withstand high temperatures or drastic changes in temperature, radar radomes, missile nozzles, supports and isolators in atomic reactors, and nuclear fission Material carriers, etc.
Silicon nitride powder has a wide range of applications. At the same time, silicon nitride powder is also a very important refractory material. At a specific temperature, it can produce an advanced non-metallic material. Users should pay attention when using silicon nitride powder. If leakage of silicon nitride powder is found, they should deal with it in time to avoid causing greater losses.
