Abstract
The invention provides a raw material and a technology for manufacturing a ceramic filter membrane. Slurry comprises a ceramic fiber sizing agent and a silicon carbide ceramic filter membrane sizing agent. The filter membrane with a uniform and smooth structure is prepared by adopting the technology through using a tape casting method, and the thickness of the membrane is easily controlled. In addition to the advantages of the traditional porous ceramic membrane, the ceramic filter membrane also has the advantages that the packing density is large, the effective separation area of the membrane in unit volume is large, and the membrane wall is thin, and the like, and the prepared double-layer non-symmetrical surface membrane has the advantages that the filtration pressure drop of a filter pipe can be effectively reduced, and the service life of the filter pipe is prolonged.
Description
Technical field
The present invention relates to filtering membrane and manufacture field, particularly relate to a kind of raw material manufacturing ceramic filter membrane, and a kind of technique manufacturing ceramic filter membrane.
Background technology
The filtration of film is solid-liquid separation technique, and it with fenestra, water is filtered, and retained by impurities in water, and do not have chemical transformation, processes easy technology, but because of fenestra very tiny, corresponding exist some technical problem.It prepares material fiber-like, synthetic resin and ceramic-like three kinds substantially.Some membrane materials have the material being weaker than the oxygenant such as salt and ozone and the material decomposed by a micro-thing.In addition, the RO as sea water desaltination has removing produce the film of the bromine of THM and can not remove the film of bromine, will determine according to purposes.
Ceramic filter periosteum is widely used in high-temperature gas and is separated in udst separation technology, becoming the key part that the industries such as material, metallurgy, chemical industry, electric power realize gas solid separation, energy-conserving and environment-protective. this material, under the prerequisite guaranteeing filtering accuracy, also will meet under actual condition the rigors in intensity, chemical resistance of concrete ability and heat-shock resistance etc.Existing ceramic filter membrane mainly contains two large classes, one class is porous ceramic film, it is one or more layers ceramic filter membrane prepared at supporter outside surface small particle size ceramic particle, have that resistance to acids and bases is good, physical strength is high, high temperature resistant, there is the features such as good emergency heat and cooling property resistance chilling performance and filtering element long service life.
Summary of the invention
The invention provides a kind of raw material and the technique that manufacture ceramic filter membrane.For realizing object of the present invention, technical scheme of the present invention is as follows:
Manufacture a raw material for ceramic filter membrane, its slurry is made up of ceramic fiber slurry and silicon carbide ceramics filtering membrane slurry.
Preferably, it is mixed by a certain percentage by silicon carbide, vitrified bond, Xylo-Mucine and distilled water that silicon carbide ceramics filters slurry, and uses magnetic agitation Homogeneous phase mixing.
Preferably, wherein ceramic bonding agent be by the potassium felspar sand powder of 64.53%, the kaolin powder of 12.2% and 23.27% quartz powder mix.
Manufacture a technique for ceramic filter membrane, it is characterized in that, the steps include:
(1) tape casting machine flow casting molding on silicon carbide ceramics block is utilized, by two kinds of slurries preparing casting film-forming successively on silicon carbide ceramics supporter disk, dried in an oven by the base film obtained, so repeating curtain coating and drying repeatedly obtained thickness is 100um ceramic interlayer mold;
(2) continue on its basis after to use silicon carbide ceramics slurry to carry out casting film-forming, and the wet base film obtained to be dried and repeated multiple times curtain coating obtains the silicon carbide ceramics filtering membrane base film that thickness is about 200um;
(3) carry out sintering at 1300 DEG C and after being incubated 3h, obtain complex silicon carbide filtering bodies sample.
Beneficial effect: the invention provides a kind of ceramic filter membrane manufacturing process, its slurry is made up of ceramic fiber slurry and silicon carbide ceramics filtering membrane slurry.This technology utilization doctor-blade casting process prepares even structure, smooth filtering membrane, and easily controls the thickness of rete.Except there is the advantage of traditional porous ceramic film own, also there is the advantages such as packing density is large, the large membranous wall of the effective separating area of unit bodies integrated membrane is thin, the double-deck asymmetric surface film tool prepared effectively can reduce the filtration pressure drop of strainer tube, extends the advantage in the work-ing life of strainer tube.
