In recent years, with the radar, the development of microwave communication technology, increasingly complex electromagnetic environment of space, in order to reduce and mitigate electromagnetic radiation on the social environment and human health hazards, the application of electromagnetic wave absorbing materials increasingly widespread, especially for high-frequency, ultra-high frequency microwave absorbing material needs, and promote the research and development of electromagnetic wave absorbing materials. Absorbing material by molding and the carrying capacity of the coating type and structure can be divided into two types, which is coated absorbing materials in its process is simple, inexpensive and widely accepted, widely used in various electronic products, equipment, electromagnetic radiation protection system. However, the use and development at home and abroad are still absorbing material density and high cost, the scope of application subject to certain restrictions.
In recent years, due to man-made glass bubble consume more energy, people turn to get hollow glass bubble fly ash from thermal power plants. In our current carbon emissions in fly ash, hollow glass bubble is generally about 50%, ash hollow glass bubble emerging as a versatile material, because of its fine particles, hollow, lightweight, high temperature insulation , insulation, wear-resistant, alkali, chemical stability and other properties, has been widely used in building materials, plastics, rubber, paint, chemical, metallurgy, marine and aerospace and other fields.
