Silicon Nitride Ceramic:
Silicon Nitride Ceramics, which we usually call ceramics, are just one of them. Refers to a type of liquid or solid material applied to the surface of an object to form a film under certain conditions to protect, decorate or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because early paints mostly use vegetable oil as the main raw material, they are also called paints. Synthetic resins have now replaced vegetable oils, so they are called coatings. Coatings are not liquid, and powder coatings are a large class of coatings. The coating is an organic chemical polymer material, and the formed coating film belongs to a polymer compound type. According to the classification of modern chemical products, coatings are fine chemical products. Modern coatings are gradually becoming a class of versatile engineering materials and an important industry in the chemical industry. There are four main functions: protection, decoration, disguise of product defects and other special effects to enhance the value of the product. In the 60 years since the founding of the People's Republic of China, along with the development of various industries in the national economy, the supporting coatings industry has gradually developed from an extremely unobtrusive small industry Diverse Pcb Ceramic Heat Sink Radiating Substrate Slice into an important industry in all areas of the national economy. After several generations of hard work and pioneering efforts, China has become the world's second largest paint producer and consumer, and has entered the mainstream of the world's coatings industry. In recent years, environmental protection has always been one of the hot topics in the field of decoration. In the second half of this year, the word will still be a major protagonist in the coatings market. It is understood that consumers in the current coatings market have higher requirements for environmental protection when purchasing products: not only will they know in detail the harmful substances content of the products, but also those products that have obtained various environmental certifications. With the continuous improvement of people's consumption level, Zhiyan Consulting not only has the willingness to purchase, but also has the economic strength to purchase. In other words, the brand awareness of consumers is increasing day by day. Paint is not only a decoration material, but also reflects the taste and essence of a person's life. In the face of growing consumer brand awareness, the shaping of the brand has become a magic weapon for coating companies to attract more passengers.
