Alumina Ceramic Foam filter is used in kitchen hood exhaust

As we know, Alumina foam ceramic is a kind of foam material made from high purity alumina. The foam ceramics have the characteristics of uniform porosity, high temperature resistance, heat shock resistance, wear resistance and chemical stability.

Widely used in casting processing, water treatment, chemical industry, environmental protection and other industries.

It is the ideal liquid aluminum filter; Catalyst support, and good sound insulation, thermal insulation material. Product shapes, sizes, and voids PPI can be designed and manufactured on request.

Alumina Ceramic foam filter plate as a carrier, which has a pretty important function for the air purification, such as used in kitchen hood exhaust.

Alumina Ceramic foam filter plate can be made into a photocatalyst carrier, coated with nano titanium dioxide on the foam ceramic carrier, excited by ultraviolet light, has strong photocatalytic oxidation and degradation characteristics, can catalyze the degradation of organic matter and microorganisms, so as to purify the air. 

When the photocatalyst is under light irradiation (including sunlight and other natural light), it can make photocatalytic reaction that is similar to photosynthesis, and it can produce free hydroxyl groups with strong oxidation capacity and reactive oxygen species with strong photoredox function.

They can oxidize and decompose various organic compounds and some inorganic substances, destroy bacterial cell membranes and solidify viral proteins, and kill bacteria and decompose organic pollutants.

Also they can decompose organic pollutants into pollution-free water (H2O) and carbon dioxide (CO2).

So, the photocatalyst has strong sterilization, deodorization, mildew prevention, antifouling and self-cleaning, air purification function, which can be meet high environmental requirements.

The characteristics of photocatalyst is to use the oxygen molecules and water molecules in the air to convert the organic matter in contact to carbon dioxide and water.

It does not change itself, but it can promote chemical reactions. Theoretically, the validity period is very long and the maintenance cost is low. At the same time, titanium dioxide itself is non-toxic and harmless, has been widely used in food, medicine, cosmetics and other fields.

Now, the applications include but not limited to oil fume gas treatment indoor air purification, industrial waste gas treatment and wastewater treatment.

Alumina Ceramic Foam filter plate is used as a variety of gas-solid, liquid-solid separation media, catalyst carrier, burner and sound absorption and environmental protection fields.
