SiC honeycomb ceramic film
Application
1.Excellent chemical stability, strong acid and alkali resistance and all organic solvents.
under strong acid, strong alkali and strong corrosion conditions, solid liquid separation can be cleaned with any organic solvent to facilitate cleaning. The initial film flux can be recovered under any conditions.
2.Good thermal stability and heat shock resistance
It can be used stably under high temperature.
3.High open porosity and large flux
Compared with the conventional pipe mold, under the same conditions, the equipment integration is high; the floor area is small; the energy consumption is low; and the investment is small.
4.Good hydrophilicity and oil repellency
It can separate oil and water efficiently.
5.The film has high bonding strength and good wear resistance.
Its service life is relatively long.
