Wind power generation is the key direction of China's new energy development and construction. As a key component of wind turbines, the market demand is increasing. However, for some time, the lack of technology for producing bearings for wind power generation has severely restricted the development of China's wind power industry.
Since 2008, Xining Special Steel Co., Ltd. has carried out technical research on the basis of fully assessing market demand, and according to the structural characteristics and working conditions of the bearings for wind power generation, special studies have been conducted on oxygen content control and non-metallic inclusion control in steels. Three years have been used to develop four types of high quality bearing steel for wind power.
He Zhi, deputy director of the Department of High-tech and Industrialization of the Department of Science and Technology of Qinghai Province, said that the review experts all agreed that the overall development level of the “High-Speed ​​Bearing Steel for Wind Power Generation†project has reached the leading level in China and is of great significance to the development of China’s wind power industry.
At present, the bearing steel for wind power generation produced by Xining Special Steel Co., Ltd. has achieved mass production, with a total production and sales of 1477.31 tons of steel, and an output value of RMB 157.450 million. The economic benefits are significant. The application of silica in PET (polyethylene terephthalate) film mainly involves the following aspects:
1. Enhanced performance: Silica can be added to PET film as a filler to improve its mechanical strength, thermal stability, optical transparency and other properties. The physical and chemical properties of PET film can be optimized by adjusting the size and dispersion of silica particles.
2. Surface modification: By depositing silica on the surface of PET film, its surface properties, such as hydrophilicity or hydrophobicity, can be changed, which is crucial for certain applications (such as packaging materials, filter membranes, etc.).
3. Antioxidant effect: Silica can be added to PET film as an antioxidant to help reduce the oxidative degradation of the film during use and extend its service life.
4. Light scattering: In some applications that require specific optical effects, silica particles can be used to scatter light to achieve special visual effects or functions.
5. Biocompatibility and antibacterial properties: In the medical and biotechnology fields, the addition of silica with specific functions (such as silica nanoparticles loaded with antibacterial agents) can give PET films biocompatibility and antibacterial properties, which are suitable for the manufacture of medical devices and biodegradable packaging materials.
6. Anti-fog treatment: Silica can be used as an anti-fog agent component for surface treatment of PET films to prevent water vapor from condensing into fog and improve transparency and visibility.
When using silica to enhance the performance of PET films, it should be noted that factors such as the amount of silica added, particle size, and dispersibility will have an important impact on the performance of the final product. Therefore, in practical applications, careful formulation design and process optimization are usually required.
Qinghai Successfully Developed Bearing Steel for Wind Power Generation
From the Ministry of Science and Technology of Qinghai Province, it was learned that in early September, the “Development of High-quality Bearing Steel for Wind Power Generation†scientific project undertaken by Xining Special Steel Co., Ltd. was approved by relevant experts inside and outside the province.
