Kerámia hab

A kerámiahab egyfajta porózus kerámiaanyag, amelyet úgy készítenek, hogy habosítószert adnak a kerámiazagyhoz, majd magas hőmérsékleten égetik.. A kapott anyag háromdimenziós hálózattal rendelkezik egymáshoz kapcsolódó pórusokból, ami olyan egyedi tulajdonságokat kölcsönöz neki, mint a magas hő- és vegyi ellenállás, kiváló szűrési képességek, és nagy mechanikai szilárdság.

Ceramic foam filter material

The basic materials of foam ceramic filters are silicon carbide, zirconium oxide, and aluminum oxide.

Applications of foam ceramics

Catalyst carrier material
Foam ceramics have high specific surface properties. As a catalyst carrier, they can increase the effective contact area and enhance the catalytic effect. Because of their advantages such as heat resistance, non-pollution, not being easily poisoned, and low cost, they have been widely used in automobile exhaust, vegyipar, and other fields to treat toxic and toxic substances: foul smell and other harmful gases.
Insulating materials
The closed pores in foam ceramics reduce heat release efficiency and reduce convection in heat propagation. They have excellent properties such as low thermal conductivity and thermal shock resistance, and are excellent heat-resistant materials.
Burner
As a porous medium burner, foam ceramic material can reduce the flame temperature through the good heat exchange rate of the ceramic material, and perform premixed combustion of various fuels in or near the surface of the inert porous ceramic, saving energy and significantly reducing COX and NOX. emission.
Sound-absorbing materials
Foam ceramics have a large number of pores with a three-dimensional network structure. The incoming sound waves cause the air in the pores to vibrate and cause friction in the ceramic tendons. The viscosity effect causes the sound waves to be converted into heat and disappear, achieving the effect of absorbing sound.
Biological materials
Porous hydroxyapatite ceramics are very similar to the inorganic components of human bones and teeth. They are non-toxic to the human body and have high biocompatibility and biological activity. Their interconnected pores are conducive to the microcirculation of tissue fluid and promote the infiltration of cells. and growth.

Preparation technology of ceramic foam filter

The main processes for preparing foam ceramics include the organic (polymer) foam infiltration process, foaming process, pore-forming agent addition process, sol-gel process, and gel injection molding process.
