Coatings and coatings play a crucial role in many industrial fields and the protection of daily living facilities, and polysilazane, with its unique and excellent properties, has opened up a wide range of applications in this field and become an important component of high-performance coatings.
In terms of high-temperature resistant coatings, there are many equipment in industrial production that need to operate stably for a long time in high-temperature environments, such as industrial furnaces, chimneys, boilers, etc. Taking industrial furnaces as an example, the internal temperature can often reach several hundred degrees Celsius or even higher during operation. Ordinary coatings are prone to decomposition and peeling at such high temperatures, and cannot effectively protect the equipment surface. The high-temperature resistant coating made of polysilazane exhibits extraordinary performance. It undergoes a series of chemical changes in high-temperature environments, gradually forming a dense and high-temperature resistant ceramic coating. This coating can firmly adhere to the surface of the equipment, effectively blocking oxygen, heat, and other contact with the metal substrate of the equipment, preventing oxidation, corrosion, and other phenomena on the equipment surface, thereby greatly extending the service life of the equipment. For chimneys, polysilazane high-temperature resistant coatings can resist the erosion of high-temperature flue gas and the chemical substances contained therein, ensuring the integrity of chimney structure, reducing the frequency of maintenance and replacement, and lowering the operating costs of enterprises. Similarly, the application of high temperature resistant polysilazane coatings on the outer and inner walls of boilers can also improve their thermal efficiency and stability, ensuring their safe and reliable provision of thermal energy for industrial production.
In the field of anti-corrosion coatings, polysilazane has outstanding performance. In the marine environment, ships are immersed in seawater for a long time, which contains a large amount of salt and various corrosive ions, which can cause serious corrosion to the hull, deck and other parts of the ship. After being coated on the surface of ships, polysilazane anti-corrosion coatings can form a continuous and dense protective film. This film has extremely low permeability and can effectively block the corrosion of ship metal by seawater, oxygen, and marine microorganisms, delay the occurrence of corrosion, extend the maintenance cycle of ships, and ensure the safety and reliability of ship navigation at sea. In the chemical industry, numerous petrochemical equipment, pipelines, etc. are also facing the threat of various corrosive substances such as strong acids, strong alkalis, and organic solvents. Polysilazane coating, with its excellent chemical stability, can maintain its integrity in these harsh chemical environments, prevent equipment and pipelines from being corroded and damaged, ensure the smooth progress of chemical production, avoid safety accidents such as leaks caused by equipment corrosion, and provide protection for chemical enterprises.
When it comes to wear-resistant coatings, polysilazane also plays an important role. In the field of mechanical manufacturing, mechanical parts such as gears and shafts are subjected to enormous frictional forces during operation, which can easily lead to wear and affect their accuracy and service life. Applying polysilazane wear-resistant coating to the surface of these parts can significantly improve their surface hardness and wear resistance. During the formation process of polysilazane coatings, their molecular structure undergoes cross-linking and other reactions, forming a surface layer with high hardness and stable structure. When subjected to friction, it can effectively resist external wear, reduce material loss on the surface of parts, maintain the dimensional accuracy and surface quality of parts, and thus improve the working efficiency and overall service life of mechanical parts. For molds, especially in injection molding, die-casting and other molding processes, molds frequently come into contact with high-temperature and high-pressure materials, which can easily cause wear and scratches. Polysilazane wear-resistant coatings can protect the surface of the mold, prolong the demolding times of the mold, reduce production costs, and improve production efficiency. Similarly, coating the surface of the cutting tool with a polysilazane coating can enhance its wear resistance, making it sharper and more durable during the cutting process, and improving machining accuracy and efficiency.
In short, the widespread application of polysilazane in the field of coatings and coatings provides strong guarantees for equipment protection and performance improvement in many industries, promoting the development of related industries towards more efficient, safe, and sustainable directions.
