On the basis of quality, according to percentage by weight be 0.05%-20% be added in organic solvent or water, then using the quality of solvent or water as
Benchmark, sequentially adds dispersant that mass percent is respectively 0.1%-5% and 1%-5% thickener, prepares and be uniformly dispersed, surely
Fixed ceramic particle, which suspends, to be starched.
（2）Porous ceramic support after cleaning is immersed in step（1）In the slurry of preparation, using the side for taking out negative pressure
Method, the ceramic particle in slurry is adsorbed in the duct on porous ceramic support surface；Taken out negative pressure is 0.01-0.1MPa,
Dipping time is to wash the ceramic particle for being attached to excess surface after 10-300s, soaking paste.
（3）In repetition（1）、（2）Process 1-5 times, the ceramic particle particle diameter used each time is the last time to use ceramics
The 1/2-2/3 of particle diameter.
（4）By step（3）In the supporter of filling ceramic powder be put into Muffle furnace and sinter 1-20 at 400-900 DEG C
Hour, generate a kind of Ceramic Composite film layer.
Usefulness of the present invention is：The more traditional film-forming method of the present invention, filming technology is simple, easily operated.2 present invention
Method only needs once sintered, and energy consumption is relatively low, is effectively prevented from traditional film-forming process soaking paste repeatedly and sinters repeatedly to cause energy consumption
Higher the problem of.3 the inventive method film is carried out in fenestra, and prepared membrane stability preferably, effectively prevent traditional system
The problem of adhesion is poor between film layer in membrane process.
