Description

technical field [0001] The invention relates to a novel low-radiation energy-saving film system, a preparation method and application thereof. Background technique [0002] With the vigorous development of the construction industry and the guidance of the national energy-saving safety policy, the energy-saving performance of building glass will receive more and more attention. In some relatively developed cities, relevant energy-saving regulations have been issued for new buildings. At the same time, with the improvement of living standards, people have higher and higher requirements for the energy-saving performance of automobiles and electrical appliances. This will not only help save energy and reduce consumption and improve the environment, but also reduce the cost of using these end products. With the economic development of China and the world, and the awakening of human beings' awareness of earth protection, green environmental protection and energy saving will be an ...

AI Technical Summary

Problems solved by technology

Existing products mainly use silicon-based or tin-based as the dielectric layer, and nickel-chromium or titanium as the protective layer. Products designed using this film system have average light-to-heat ratio (LSG) performance. Due to the limitations of the material itself , there is limited room for further performance optimization

At the same time, there is still room for improvement in terms of machinability, mechanical properties of the film surface, water vapor transmission rate, yield rate of the coating production process, and requirements for coating equipment for products produced using this film system.
