corrosion resistant Si3N4 ceramic machinery parts
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
High-temperature ceramic wear-resistant materials are widely used in power plants and steel smelters. The temperature of steel smelting mills is between 800 and 1200 degrees. Therefore, materials are required to withstand high temperatures and the requirements for wear resistance are very strict. Many manufacturers use refractory castables to solve the wear problem of this part, but the effect is not very satisfactory, because refractory castables have a very good effect on high temperature resistance, but the wear resistance will be seriously degraded after high temperature. High-temperature wear-resistant ceramic coating fills this gap. Its special high-temperature resistant glue can form a sintering reaction with the material during the sintering process. The compressive strength of the ceramic coating layer after sintering reaction can reach 161, and the flexural strength can reach 17.8. And can continue to play its role. Ceramic wear-resistant materials have high requirements for mixing and construction. The mixing time is about 15 minutes. The mixing time is closely related to its unique raw material configuration and special glue. The stirred high temperature and wear resistant ceramic coating is taken out from the mixer, transported to the construction site and poured onto a clean platform. Each time about 2 kg of material is taken out and applied to the welded tortoise shell net or V-shaped hook nail. Firmly smooth the compaction to ensure that the material can be firmly bonded to the surface of the steel plate or the tortoise shell, and then hammered with a hammer or rubber hammer to increase its density strength.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
