At the technical level
Complex preparation process and cost issues: The preparation process of polysilazane is relatively complex, with strict requirements for reaction conditions (such as temperature, pressure, catalyst, etc.) during the synthesis process, and the yield is often low, resulting in high production costs. In the large-scale construction and renovation of smart grids, a large amount of insulation materials are required, and high costs will limit the widespread application of polysilazane.
Performance optimization requirements: Although polysilazane itself has certain insulation performance, some special scenarios in the smart grid, such as ultra-high voltage transmission, high-frequency high-speed signal transmission, etc., put forward higher requirements on the electrical performance, heat resistance, aging resistance, etc. of insulation materials. Further optimization of the performance of polysilazane through modification, composite and other technological means is needed to meet the diverse needs of smart grids.
Difficulty in verifying long-term stability: The service life of smart grid equipment is usually required to be 20 years or even longer. Polysilazane, as an insulation material, may be affected by various factors such as electric field, temperature, humidity, and chemical substances during long-term operation, and its performance may change. Due to the complexity and variability of the actual operating environment, it is difficult to fully simulate under laboratory conditions, which poses challenges for the long-term stability verification of the application of polysilazane in smart grids.
At the market level
Low market awareness and acceptance: Compared to traditional insulation materials such as epoxy resin and organosilicon, the application of polysilazane in the smart grid field is still in a relatively early stage, and its market awareness and acceptance are relatively low. Power grid companies and related equipment manufacturers may be more inclined to use mature and reliable traditional insulation materials, and have a certain wait-and-see attitude towards new types of polysilazane materials.
Intense market competition: The smart grid insulation material market is fiercely competitive, and traditional insulation material suppliers have already occupied a large market share and are constantly upgrading their technology and innovating their products. As a latecomer, polysilazane needs to have significant advantages in performance, price, service, and other aspects in order to compete for a place in the market.
Incomplete industry standards and regulations: Currently, the relevant industry standards and regulations for the application of polysilazane in the smart grid field are not yet complete, lacking unified performance indicators, testing methods, and application guidelines. This makes the design, production, and application of polysilazane products lack clear basis, which is not conducive to their market promotion and application.
