Silicon Nitride Ceramic:
There are many reasons why the surface processing of stainless steel is important for Silicon Nitride Ceramics in the field of construction applications. The corrosive environment requires a smooth surface because the surface is smooth and not easy to accumulate. The deposit of dirt will cause stainless steel to rust and even cause corrosion.
In a spacious hall, stainless steel is the most commonly used material for elevator decorative panels. Although the fingerprints on the surface can be wiped off, it affects the appearance. Therefore, it is best to choose a suitable surface to prevent fingerprints from being left.
Sanitary conditions are very important to many industries, such as food processing, catering, brewing, and chemicals. In these applications, the surface must be easy to clean every day, and chemical cleaning agents are often used. Silicon nitride is the best material in this regard. In public places, the surface of stainless steel is often scribbled. However, an important feature of it is that they can be washed away. This is a significant feature of stainless steel over aluminum. . It is easy to leave marks on the surface of aluminum, which is often difficult to remove. When cleaning the surface of stainless steel, you should follow the lines of stainless steel, because some of the lines processed on the surface are unidirectional. Silicon Nitride Ceramic Structural Parts is most suitable for hospitals or other areas where sanitary conditions are critical, such as food processing, catering, brewing, and chemicals. This is not only because it is easy to clean every day, and sometimes chemical cleaning agents are used, but also because it is not easy Breed bacteria. Tests show that the performance in this respect is the same as that of glass and ceramics.
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.
