◎ Overview

Development of inorganic film began in the 1940s, has developed has gone through three stages. Since the development of high performance inorganic membranes and inorganic materials science, the application of the growing field of inorganic membranes, inorganic membranes and membrane processes and catalytic reactions catalyzed reaction process constituted is considered one of the future direction of development of the three catalytic disciplines. Therefore the application of inorganic membranes become a hot research and development in the field of membrane technology.

Inorganic membrane country began in the 20th century in the late 1980s, by supporting the National Natural Science Foundation of China and various ministries, China has been able to prepare in the laboratory of inorganic microfiltration membrane, ultrafiltration membrane and metal palladium membrane.

In the 1990s, the National Science and inorganic ceramic membrane technology organizations industrialization of scientific and technological research, and promote the industrialization process of ceramic microfiltration membrane.

2002 Seventh International Conference of the inorganic film in China was held, marking the research and industrial application of inorganic membranes have been into the international advanced level.

◎ inorganic membrane characteristics

Processed inorganic film is made of an inorganic material, is a solid film, inorganic materials science-based inorganic film has the advantage of polymer membranes unmatched:

◇ narrow pore size distribution, high separation efficiency, stable filtering effect.

◇ good chemical stability, acid, alkali, organic solvents.

◇ high temperature, available and high-temperature steam sterilization recoil regeneration.

◇ anti-microbial contamination ability, suitable for applications in the biomedical field.

◇ mechanical strength, can be a high pressure backwash, regeneration ability.

◇ no leachables generation, will not produce secondary pollution, will not have a negative impact on the separation of materials.

◇ separation process is simple, low power consumption, easy operation running.

◇ film long service life.
