High-Performance Plate

产品描述
Silicon nitride ceramic products performance characteristics and applications:
 
Because silicon nitride ceramics have high mechanical strength, wear resistance, acid and alkali resistance, good thermal stability, and self-lubricating properties, they are required in special engineering applications such as aerospace, petroleum, and high temperature, corrosion, and mechanical wear. The use of silicon nitride ceramic parts in chemical industry is of great significance. It can be widely applied to the anti-wear, high-strength, high-temperature, corrosion-resistant and other elements in the motor, electrical, mechanical, and machining industries or replace the original traditional metal parts. Can customize the appearance according to customer specifications.
Insulation electric strength: 2500V, 50Hz at room temperature, no breakdown for one minute.
 
 
Acid corrosion resistance:
 
Boiling 6h in 5% sulfuric acid solution, corrosion rate <10g/m2.h
 
 
Alkali corrosion resistance:
 
30% boiling sodium hydroxide solution 6h, corrosion rate <0.6g/m2.h.
