What is ceramic membrane?

In our daily life, we can often see that metals, food, drinks and other items are covered with a protective film to avoid damage or deterioration. Among many protective films, ceramic membrane is a common one. So what is ceramic membrane? Introduce it to everyone in this article.

Ceramic membrane, also known as inorganic ceramic membrane, is a solid membrane material in membrane separation technology. Ceramic membrane is mainly made of inorganic ceramic materials with different specifications, such as alumina, zirconia, titania, silica, etc., by surface coating and high temperature firing. It has the characteristics of high temperature resistance, chemical corrosion resistance, cleanability and long service life, and is widely used in many fields such as food, beverage, deep processing of plants (drugs), biomedicine and so on.

What are the advantages of ceramic membranes?

1, the ceramic membrane has excellent chemical stability, excellent acid resistance, alkali resistance and organic solvent resistance, and a wide range of PH values.

2. European ceramic membrane has high mechanical strength, easy regeneration and long service life.

3. Ceramic membrane has excellent thermal stability and can be used in high temperature and high pressure systems.

4. The ceramic membrane is washable, non-toxic and will not pollute the separated articles.

5. The ceramic membrane has narrow pore size distribution rate and high separation accuracy, and can be used as a filtration membrane.

What are the types of ceramic membranes?

1, porous membrane

There are three kinds of porous ceramic membranes: flat membrane, tubular membrane and multi-channel membrane, in which the flat membrane is mainly used for small-scale industrial production and laboratory research. Tubular membrane has been gradually eliminated because of its poor strength. Multi-channel ceramic membranes are used in large-scale applications.

2. Packaging film

Ceramic membrane can also be used in the field of food packaging. Ceramic membrane can be used as transparent coated ceramic with high functionality and good environmental adaptability. Although the price of this film is relatively high at present, its physical properties need to be further discussed, but it will occupy an important position in the future food packaging.

The above is an introduction about what ceramic membrane is, and I hope you can know something about ceramic membrane and its performance.
