Problems solved by technology

However, the production technology of low-density and high-strength hollow glass microspheres is mainly monopolized by a few manufacturers such as 3M, Emerson, and PQ. Domestic high-performance hollow glass microspheres are completely dependent on imports, resulting in high prices for lightweight and high-strength solid buoyancy materials, making it difficult to achieve independent industrial production.
However, ceramic hollow balls generally have high density, poor structural uniformity, and high energy consumption in the production process, so it is difficult to meet the needs of deep water solid buoyancy materials.
[0003] Fiber-reinforced resin composite materials have excellent properties such as high strength, low density, and corrosion resistance, but so far, there is no patent report on fiber-reinforced resin hollow spheres that can be used as solid buoyancy materials in my country
