Silicon Nitride Ceramic:
Silicon Nitride Ceramics uses traditional carbon steel color-coated panels as building materials, and there are defects such as poor material corrosion resistance, strength, and toughness. To ensure safety, many factories in the southeast coast and other regions need to replace their roofs every two years, which is costly. In order to solve this problem, the construction and steel industries continue to explore and practice, and propose the use of corrosion-resistant and ductile stainless steel as roof building materials. However, the stainless steel material has a single color and is easy to reflect light, which is unsightly and can cause light pollution. According to reports, the color steel production process uses coloring technology with independent intellectual property rights without increasing steel production capacity, and improves the production efficiency of color steel through the "cold rolling-coloring" short-process production process, and realizes the integration of stainless steel body and coloring. . This kind of color steel plate production process is still the first in China, filling the world blank in the field of stainless steel continuous coloring production, and realizing the effective combination of beautiful color and safe anti-corrosion performance of stainless steel materials. The metal surface exposed in the corrosive environment undergoes an electrochemical reaction or a chemical reaction, and is uniformly corroded. In the passive film on the stainless steel surface, the weak corrosion resistance is formed due to the self-excited reaction and the formation of small pores, coupled with the approach of chloride ions, the formation of a strong corrosive solution accelerates the rate of the corrosion reaction. There is also intergranular corrosion cracking in stainless steel, all of which have a destructive effect on the passivation film on the surface of Silicon Nitride Ceramic Plate. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life. When cleaning the stainless steel surface, you must be careful not to scratch the surface. Avoid using bleaching ingredients and abrasive detergents, steel balls, abrasive tools, etc. To remove the detergent, rinse the surface with clean water after washing.
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.
