Glass fiber is an inorganic non-metallic material with excellent performance. High-frequency, high-speed, high-fidelity signal transmission 5G communications, the Internet of Things and other emerging industries are developing rapidly, and technological upgrades in new energy, rail transit and other fields are inseparable from low dielectric, low loss, high strength, high modulus, etc. The characteristic special glass fiber material serves as support.
In the past, the core technology of special glass fiber has been monopolized by foreign giants for a long time. For this reason, with the support of the National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology, CQGJ Composites Technology Group has cooperated with Chongqing University of Technology and Sichuan University after nearly ten years of systematic research and production. Collaborative research and research have overcome key bottlenecks such as small mass production of special glass fibers, difficult molding, high energy consumption, serious environmental pollution, and unstable quality.
At the Science and Technology Award Conference held on September 22, CQGJ's "High-performance Special Glass Fiber and Key Technology Innovation and Industrialization of Green Manufacturing" won the first prize of Science and Technology Progress Award.
"We have developed a series of special glass fibers that have reached the international advanced level and can be produced on a large scale." The person in charge of the lead unit of the CQGJ project introduced, such as low dielectric glass fibers with a dielectric constant of less than 4.6 and a dielectric loss of less than 0.001. Has realized the world's largest commercial production. At the same time, it also overcomes the difficult and unstable quality of special-shaped special glass fiber production. It is the first in China to realize the stable production of high-performance special glass fiber with special-shaped ratio of 1:3 and 1:4. The maximum filling of special-shaped fiber can reach 70. %, filling the domestic gap.
Focusing on related research results, the CQGJ project team has obtained 28 authorized invention patents and 11 other intellectual property rights. It has developed a series of special glass fibers with the largest variety in the world, with a domestic market share of more than 30%. Fortune 500 companies have launched cooperation.
As China's largest special glass fiber R&D and production base, it plans to build 7 special glass fiber production lines. It is estimated that after all construction is completed in 2022, it can achieve an annual sales income of 600 million yuan.
