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 symmetric film, entry of film needs strict pre-treatment.
4.Tungsten oxide inorganic ceramic film has higher strength, it can resist pressure to 16bar, the supporting part can resist pressure to 30bar. It can ensure the dealing effects and stability in quality.
5.Tungsten oxide inorganic ceramic film has high insulating property.
6.Service life of tungsten oxide inorganic ceramic film is more than 5 years, however the organic film is only 3~6 months.
7.Chemical stability and thermal stability of tungsten oxide inorganic ceramic film is better than organic film, the strong acid, alkali and oxidizing agent can be used as detergent, steam sterilization can be applied directly. However, organic film can not be operated under the above mentioned conditions.
