The breakthrough in polysilazane technology has opened a new chapter in the application of materials
Recently, the field of polysilazane materials has witnessed a major breakthrough. A series of innovative achievements have not only enhanced the performance of polysilazane but also broadened its application boundaries, bringing new development opportunities to multiple industries.
1. Break the monopoly and achieve domestic production
Once upon a time, high-end polysilazane technology was long monopolized by enterprises from Europe, America, Germany, Japan, etc. The unit price of the product was as high as 3,000 yuan per kilogram, and it was banned from sale in China. To break this situation, domestic enterprises and research teams have actively engaged in research and development. Nowadays, China has successfully achieved the domestic production of polysilazane through its independently developed liquid precursor conversion process, reducing the cost to 800 yuan per kilogram and realizing an annual production capacity of over 100 tons. This achievement not only fills the domestic market gap but also enhances China's international competitiveness in the field of polysilazane.
2. Performance optimization to meet diverse demands
Researchers have made remarkable progress in the performance optimization of polysilazane. Through reactions such as grafting, chain extension and modification, and by selecting appropriate catalysts and reaction conditions, the target polymers with molecular weights ranging from 2×10³ to 1.6×10⁵ were successfully prepared, which greatly enhanced the product performance of organic polysilazane resins. The newly developed polysilazane material not only maintains excellent high-temperature resistance, corrosion resistance, insulation and other properties, but also significantly improves its mechanical properties such as hardness and toughness. For instance, under high-temperature vibration conditions, the intelligent coating prepared by gradient doping technology can still maintain a complete interface bonding force, providing a reliable solution for fields with extremely high requirements for material performance, such as high-speed rail braking systems.
3. Application expansion, covering multiple industry fields
With the improvement of performance and the reduction of cost, the application fields of polysilazane have been further expanded. In the aerospace field, it is widely used in key parts such as rocket engine coatings and aircraft thermal barrier systems due to its outstanding high-temperature resistance. In the high-end equipment manufacturing of semiconductors, polysilazane, as a coating material, effectively meets the industry's demands for high precision and high stability of materials. In the field of building chemicals, polysilazane coatings have become an ideal choice for the protection of building exteriors and industrial facilities due to their excellent waterproof and acid and alkali corrosion resistance properties. In addition, in the preparation of ceramic-based materials, polysilazane, as an important ceramic precursor, has promoted the research and development and application of new ceramic materials.
4. Environmental protection upgrade leads green development
While emphasizing performance and application, the environmental protection performance of polysilazane materials has also been enhanced. The advent of environmentally friendly water-based polysilazane coatings marks the entry of this technology into a green development stage. Compared with traditional solvent-based coatings, the new water-based system reduces VOC emissions by more than 90% while maintaining the high-strength paint performance. In high-temperature industrial scenarios such as electric arc furnaces, this coating, which combines high-temperature resistance with environmental friendliness, is gradually replacing chromium-containing heavy metal anti-corrosion materials. It not only meets the material performance requirements of industrial production but also conforms to the current trend of environmental protection development.
The breakthrough in polysilazane technology has opened a new chapter for material applications. From breaking foreign monopolies to performance optimization, application expansion and environmental protection upgrades, polysilazane is driving the transformation and development of multiple industries in a brand-new posture, and its future market prospects are very broad.
