Description
Technical field
The present invention relates to technical field of membrane separation, particularly relate to a kind of flat board ceramic honey comb film and preparation method thereof.
Background technology
Membrane separation technique is by one of new and high technology being referred to as 21st century most application prospect in the world.Ceramic membrane is
A new generation's membrane separation technique, is with Al2O3、ZrO2、TiO2、SiO2, the tool that is made through a series of special process of the raw material such as SiC
There is the separation material of loose structure.Ceramic membrane is divided into tubulose, multichannel and tabular according to shape.With traditional tubulose and manifold
Road ceramic membrane is different, and ceramic membrane uses external-compression type to filter, and the outer surface of ceramic membrane is stratum disjunctum, and fenestra road is that penetrating fluid leads to
Road.Owing to having eggshell effect, using this structure, for ultra-thin ceramic membrane, the wall thickness of its supporter can be as small as
1mm, the thickness of whole Flat Membrane is 3～5mm, thus significantly reduces the osmotic resistance of ceramic membrane.But, this structure also must
So bring problems with:
(1) requirement to forming technique is added.In particular by extrusion moulding, need to control pug character to avoid
Ceramic film support deforms.
(2) bulk strength of ceramic membrane is inadequate.Although the buckling strength of membrane material is not changed in, but, due to supporter
Thickness is less, and the pressure that ceramic membrane can bear is less, easily snaps off.
(3) membrane area of unit volume is less.Owing to using slab construction, the external surface area of ceramic membrane is film surface
Long-pending, for assembly, the membrane area of the ceramic membrane can installed in unit volume is less than Multichannel ceramic membrane.
(4) the preparation difficulty of ceramic membrane separation layer increases.Owing to the thickness of supporter reduces, tradition cement-dipping method is used to be difficult to
Obtain enough thicknesses of layers (general ＜ 10 μm), be easily generated film defect.
At present, prior art, for the preparation of tabular ceramic film support, also has employing injection moulding, gel injection-moulding to become
The methods such as type, but consider from performance and the preparation efficiency of ceramic film support, extrusion moulding still has obvious advantage.So
And, the method for prior art extrusion molding not technology of preparing for ultra-thin ceramic membrane proposes to be effectively improved and arrange
Execute.Additionally, be to improve unit volume membrane area further, currently also research and develop large-sized thin wall hollow flat ceramic
Film.But size is the biggest, either still it is dried in the later stage in molding and is all easily caused deformation in calcination process, particularly can increase
Add ceramic membrane and the probability of film defect occurs.And, along with the change of size is big, thin plate easily occurs in membrane filtration processes that vibration is existing
As, easily rupture because of resonance.
In terms of preparative separation film layer, prior art generally uses cement-dipping method, is coated with in addition with using vacuum impregnation
The method of film, but not special adaptations.To this end, also researched and developed plasma spraying preparative separation film layer, but substantially increase
Ceramic membrane cost；And using compressed air is source of the gas, preparing film layer by spraying, under compressed-air actuated brushing, film layer holds
Easily ftracture because of rapid draing.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of combined flat plate ceramic honey comb film, with flat
