Description
Technical field
The present invention relates to Light anticorrosive ceramic tile preparing technical field, is used to prepare lightweight anti-corrosion pottery more particularly, to one kind
The equipment of ceramic tile.
Background technology
Disclose a kind of preparation method of Light anticorrosive ceramic tile in Chinese patent literature CN103664225A, including with
Lower step：The raw material matched is subjected to mixed grinding first, the mesh of fineness of grind to 150 mesh ~ 180, obtains powder；Then by powder
Material carries out drying and processing, and drying temperature is 150 ~ 200 DEG C, then by dried powder it is die-filling enter kiln high temperature sintering, temperature in kiln
Spend for 1200~1300 DEG C, klining is 5 ~ 8 hours, draws ceramic body；Finally the ceramic body baked is cut, obtained into
Product.Also disclose and be first warming up to 600 DEG C from room temperature with 25 DEG C/min firing rate for kiln temperature, be incubated 1h, then with
15 DEG C/min programming rate rises to 1200 ~ 1300 DEG C, is incubated 2h, and 900 DEG C are being down to 30 DEG C/min speed, and insulation 3 ~
4h, finally treat that it is normally cooled to room temperature, obtain finished product.
Although the Light anticorrosive ceramic tile that the above method is prepared also has light, the effect of service life length, resistance to compression
Intensity is also preferable；But it also has the defects of certain, unstable product quality, the cracking of larger batch products and resistance to occurs
The undesirable situation of corrosive nature.
A kind of the new method of Light anticorrosive ceramic tile is prepared therefore, it is necessary to study.
The content of the invention
The technical problem to be solved in the present invention be to provide it is a kind of it is light, water absorption rate is high, corrosion-resistant intensity is good, properties of product
The preparation method of stable Light anticorrosive ceramic tile.
In order to solve the above technical problems, the technical solution adopted by the present invention is, the preparation method of the Light anticorrosive ceramic tile
Comprise the following steps：
（1）Material metage：By ceramic dead meal, calcite, foaming agent, comburant, carborundum and floating bead according to pre-
Fixed parts by weight are weighed；
（2）Grinding is into slurry：By step（1）Weighted material, which is put into ball mill, carries out grinding into slurry,
The time that material carries out ball milling in ball mill is 24 hours, and material grinding to mesh number is 400 mesh；And use vacuum compressor will
The good slurry of grinding is sprayed into sieving equipment；
（3）Vibration screening：Slurry carries out vibration screening in sieving equipment；
（4）Filtering means dehydration：The slurry pasted on potsherd is subjected to filtering means dehydration by the way of vacuumizing, pressure is
0.4Mpa, then the slurry for passing through filtering means dehydration on potsherd is scraped；
（5）Dry：Using conveyer belt by the step（4）In the material that is scraped from potsherd be delivered in dehydration dryer
Dehydration is dried, drying and dehydrating temperature is 150 ~ 220 DEG C, and the time is 20 ~ 30 minutes, obtains material caking；
（6）It is broken：By the step（5）Material caking after middle drying and dehydrating carries out broken material powder；
（7）Load grinding tool to fire：By the step（6）In obtained material powder be fitted into the mould in kiln car device,
It is delivered to again in S-shaped or snakelike kiln and carries out motion firing；
（8）Excision forming：By step（7）The Light anticorrosive ceramic tile of middle firing is cut according to preliminary dimension, must be produced
Product.
It is 400 mesh by material grinding to mesh number using above-mentioned technical proposal, and in step（4）Middle progress vacuum filter takes off
Water, and combine step（5）In drying process, influencing each other between strength imparting material is more beneficial for, as a result of filtering means dehydration
And drying steps, can preferably play the effect of foaming agent, such particle is relative to be can be larger, reduce powder technology into
This, obtained finished product mesopore is larger, can preferably absorb moisture, improve water absorption rate；In addition, using S-shaped or snakelike
Motion firing is carried out in kiln, sintering procedure has continuity, improves end properties stability；The main work of vibration screening
With being that will be greater than the particulate removals of 400 mesh outside, by mesh number control below 400 mesh, the foaming effect for passing through fine particle is real
It is existing light.Using the preparation method of the Light anticorrosive ceramic tile of the present invention, obtained finished product is light, water absorption rate is high, corrosion-resistant strong
Spend, properties of product stabilization.
Preferable scheme is the step（7）In, the time that kiln car device is walked in kiln is 16 ~ 20 hours, is fired
Influence of the time for properties of product is extremely important, inventor by combining the analysis of the composition proportion of material, it is creative general
Firing time was controlled at 16 ~ 20 hours, was effectively guaranteed the stable performance of product.
Preferable scheme is, in the step（5）In, by moisture in dried material caking below 10%,
The content of moisture is too high, can influence the physical property of brick body in sintering procedure, especially for volume to weight ratio and the shadow of thermal conductivity factor
Ring compression strength that is very big, and then influenceing brick body.
Preferable scheme is, in the step（1）In, the parts by weight of each material are：Ceramic 30 ~ 40 parts of dead meal, Fang Xie
30 ~ 50 parts of 10 ~ 15 parts of stone, 2 ~ 5 parts of foaming agent, 1 ~ 5 part of comburant, 0.5 ~ 5 part of carborundum and floating bead.
The Light anticorrosive ceramic tile that inventor is prepared by the material proportion in creative work discovery such scheme
There is more excellent effect in performance.
Preferable scheme is, in the step（1）Acid proofing agent is additionally added, parts by weight are 1 ~ 8 part.It is extra to add acid proofing agent
It is to improve the acid resistance of Light anticorrosive ceramic tile.
Preferable scheme is that the composition percentage composition of the acid proofing agent is：SiO295-99.7%, Fe2O3 It is no more than
0.03%, surplus is impurity；The acid proofing agent is in the limited product sold in market.
Preferable scheme is, in step（7）In, kiln car firing of being walked in kiln is divided into initial stage, mid-term rank
Section and later stage, stage, the temperature of kiln car are warming up to 600 DEG C with 25 DEG C/min firing rate from room temperature, are incubated 4 in the early stage
Hour；In mid-term stage, 1200 ~ 1250 DEG C are risen to 15 DEG C/min programming rate, is incubated 3 ~ 4 hours；During the late stages of developmet, with
30 DEG C/min speed is down to 900 DEG C, is incubated 9 hours.
Initial stage is mainly so that the stable rising of material so that they reach interactional combination temperature point, enter
Row is preliminary to be fired, and mid-term stage so that the intensification that influences each other between material, is further fired；Later stage is to mid-term
The brick body that stage is formed is consolidated in performance so that irreversible between material.
The Light anticorrosive ceramic tile being prepared using the inventive method, compression strength ＞ 2.8MPa, it is sufficient to resist flue gas
Long-term wash away；（2）80 DEG C of leaching 40%H2SO4Under the conditions of, compression strength ＞ 2.7MPa after 7 days, various low temperature diluted acids can be resisted
The corrosion of liquid；（3）The special closedcells structure having and extremely low water absorption rate, effectively resist acid accumulator penetration；（4）Lightweight is prevented
Rotten ceramics turn by 1200 ~ 1250 DEG C of kiln high-temperature firings having of forming it is closed, do not penetrate foam structure, low heat conductivity mutually
Light material, effectively keep cigarette temperature and isolate heat erosion of the high-temperature flue gas to steel inner cylinder wall.
