Description
Technical field
The present invention relates to a kind of preparation method of plate diamond spar ceramic film support, belong to ceramic membrane technology field.
Background technology
Since the eighties in 20th century porous ceramic film first since French industrial application, its high score is from effect
Rate, high temperature resistant, solvent resistant, antimicrobial, resistance to acids and bases, high mechanical properties and the excellent properties such as easy cleaning is renewable are gradually by work
Industry receives and has been widely applied.Inorganic ceramic membrane can be used for gas separation, liquid isolation of purified and membrane reactor,
Food industry, pharmacy and bioengineering, chemistry and the field such as petrochemical industry and environmental protection are widely used.When
Before, the increasingly raising with world wide to process industrial energy-conserving and emission-cutting technology demand, the nanofiltration membrane with nanostructured,
Pervaporation membrane and gas separation membrane have turned into one of the study hotspot and following important developing direction in ceramic membrane field.
Porous ceramic film typically has three layers of unsymmetric structure, i.e., the top layer of centrifugation, transition zone and supporting layer by.
Must have enough mechanical strengths, permeance property higher, the smooth and preferable acid-proof alkaline in surface as supporting layer.Support
The quality of body performance directly affects the preparation of follow-up porous ceramic film.
The electro-corundum (10~80 μm of particle diameter) that current supporter is mainly by being surface-treated by shaping (is carried as aggregate
For permeance property) prepare, on the one hand, the electro-corundum bulky grain sintering activity being surface-treated by shaping is relatively low, and this just leads
Cause inorganic ceramic film support sintering temperature is higher, and for example its firing temperature of Japanese NGK company is 1700 DEG C, and U.S. Pall
Its firing temperature of company reaches 1800 DEG C；On the other hand, it is this by shaping be surface-treated electro-corundum price it is higher (>=
20000 yuan/ton), its accounting in inorganic ceramic film support formula is (mass percent reaches 70-85%) high.Therefore, make
It is high into inorganic ceramic membrane product price, have impact on the large scale application of the product.
Because plate diamond spar calcining heat is more lower slightly than electro-corundum temperature, with the presence of Minute pores rate, its particle is to water
Suction-operated makes the extremely difficult extrusion pug for being made function admirable of the material, and pug easily produces cracking etc. to lack in drying process
Fall into, although this allow for plate diamond spar price than current supporter commonly use by shaping be surface-treated electro-corundum valency
The low 60-70% of lattice, but the technology application of the material is there is no in the industry.
The content of the invention
It is an object of the invention to provide a kind of preparation method of plate diamond spar ceramic film support, its is simple and easy to apply, cost
Low, sintering temperature is low, energy-saving and emission-reduction.
The preparation method of plate diamond spar ceramic film support of the present invention, be with alumina powder, promote agglutinant and
The plate diamond spar of pretreatment is raw material, and pug is made after stirring, then by pug extrusion molding and sintering, obtains described tabular
Corundum ceramic film support；The pretreatment is that the particle surface of plate diamond spar is modified using surface modifier.
The surface modifier is hydraulic oil, machine oil or tung oil, and addition is the 2-7% of plate diamond spar powder quality.
The detailed process of the pretreatment is as follows：To surface modifier is persistently slowly added in plate diamond spar powder, fully
Stirring mixing, infiltration package status are in surface modifier by the particle surface of plate diamond spar.
The particle diameter of the plate diamond spar is 30-50 μm；The particle diameter of alumina powder is 0.5-1 μm.
In the raw material, the mass percent of the plate diamond spar of pretreatment is 70-85%, the quality percentage of alumina powder
Than being 13-25%, the mass percent for promoting agglutinant is 0.5-5%.
The rush agglutinant is magnesia, titanium oxide or lanthana.
After the stirring 1h, deionized water, organic bond and lubricant is added to be made pug.
The organic bond is polyvinyl alcohol, cellulose or dextrin；Lubricant is the one kind or two in glycerine or white oil
Kind.
The addition of the deionized water is the 5-20% of material quality；The addition of organic bond is material quality
1-10%；The addition of lubricant is the 1-10% of material quality.
During the extrusion molding, pug is extruded into the supporter of sheet, single tube and multichannel.
During the sintering, temperature is 1580-1620 DEG C, and heating rate is 0.5-3 DEG C/min, and soaking time is 1-3 hours.
The cost of raw material (>=20000 yuan/ton) high instant invention overcomes generally existing in industry, sintering temperature are high
(1650-1800 DEG C), the problems such as energy consumption is big, there is provided a kind of preparation method for preparing ceramic film support of low cost.
Using the plate diamond spar having stable high-temperature performance, its particle is the nearly spherical particle of 30-50 μm of diameter, particle to the present invention
Mobile performance and dispersive property are good in pug, therefore, have an opportunity to produce more contact point between particle and particle, in sintering
During, these contact points improve the power of solid-phase sintering, promote the formation of neck sintering, effectively reduce and burn till temperature
Degree.
The present invention carries out particle surface pretreatment to above plate diamond spar using surface modifier, modified by surface, gram
Taken the current material prepare supporter generally existing particle is loose, plasticity of slurry extreme difference, season cracking the problems such as so that
Supporter extrusion molding and blue or green base dry qualification rate and increase substantially.
Compared with prior art, the invention has the advantages that：
(1) present invention is prepared for a kind of low (the cost of material reduction of cost of material by the modified pretreatment in plate diamond spar surface
60-70%), high (pure water flux is 5- for sintering temperature low (1580-1620 DEG C), high mechanical strength (20-50MPa), permeance property
10m3·m-2·h-1·bar-1), the ceramic film support of fine corrosion resistance, its porosity be 30-40%, average hole
Footpath is 10 μm.
(2) preparation method is simple and easy to apply, beneficial to industrialized production.
(3) ceramic film support for preparing, for ceramic membrane series of products large-scale promotion at home, in the industry cost
Sustainable reduction, energy-saving and environmental improvement cost persistently reduce significant.
