Tungsten Oxide Inorganic Ceramic Film
Tungsten oxide inorganic ceramic film has high efficiency, high temperature resistance, high performance and stable chemical property. It has wide application field. Compared to organic film, it has following characteristics: 1.Tungsten oxide inorganic ceramic film has small pore size distribution which shows as normal distribution, 80% of them has error within ±10%. For example, the 0.05um film, among which 80% of pores are 0.049um-0.051um, it insures the stability of the applied film. This has a big difference from organic film which the pore size distributes uniformly. 2.Porosity of tungsten oxide can reach 35%-40% which ensures film flux. 3.Tungsten oxide inorganic ceramic film departure structure is more reasonable, there are supporting layer and separating layer, pore size is 5-10、1.0、0.6、0.2um, it becomes really gradient films which improve pollutant-resistance of film. The separating layer is even thinner which is easier to clean and wash. On the contrary, organic film is...
