Description
Technical field
The production method that the present invention discloses a kind of large, honeycomb ceramic tube belongs to inorganic non-metallic material technology of preparing neck
Domain.
Background technique
Under the historical background of current scientific and technological high speed development, some special trades to the application demand of ceramic product increasingly
Extensively.Ceramic product has acid and alkali-resistance, high temperature resistant, high intensity, high thermal conductivity, many excellent properties such as height insulation.The present invention discloses
Honeycombed ceramic tube can be used as the conveyance conduit for being applied to the high corrosive liquids such as high-temperature acid, alkali, Special high-temperature cable is worn
The special industries such as spool.It is arranged side by side compared to common a plurality of single tube, overall aesthetics is improved while big quantity space is saved in layout.
In industrial production, equipment manufacturing, globality, compactedness requirement to layout bring huge convenience.
Ceramic honey comb pipe production method mostly uses extrusion molding and casting forming method to make green body at present, then through burning
It ties and obtains product.The product size of above method production is but by the stringent limitation of technique.Such as: as the size of caliber increases
Greatly, the model of extrusion shaping machine need to be promoted constantly, and cost of investment is huge, while blank strength is low, and weight is again larger, and green body is easy
Deformation is not appropriate for large size product molding in this way.Compared to extrusion molding, although moulding by casting has production flexibly, fastly
Speed, the low feature of preparation cost, but and be suitble to all ceramic materials, essentially consist in the slurry preparation characteristic thousand of different ceramic materials
Poor ten thousand are not, and the green body water content of this method production is big, and dehydration and drying is easy to cause blank cracking, and the production cycle is long, operation difficulty
Greatly, yield rate is very low, while it is not high to be burnt into product density, dimensional accuracy.
Summary of the invention
To solve the above problems, the production method present invention aims at a kind of large, honeycomb ceramic tube is proposed, has solved
Traditional handicraft cannot achieve efficient, inexpensive, high-quality product production method problem.
To realize above-mentioned technology, and reach above-mentioned technical effect, the present invention is achieved by the following scheme.A kind of large, honeycomb
The production method of ceramic tube, steps are as follows: (1) producing multichannel disjunctor rubber evacuated mould according to pipe shape and size design
③；(2) with hard plate materials such as perforated steel plates, the inside and outside support framework structure of multichannel disjunctor rubber evacuated mould is produced 4., and
It is fitted together closely with multichannel disjunctor rubber evacuated mould, becomes ceramic honey comb pipe mold；(3) ceramic prilling powder is poured into rubber
In the multichannel cavity of glue evacuated mould, after filling up jolt ramming, 2. material filling mouth is blocked with sealing-plug and is 1. compacted be tamping with cover board；
(4) the canned mold of (3) step is put into cold isostatic press and is suppressed, up to ceramic honey comb pipe body after pressure release demoulding,
Ceramic product is obtained after high temperature sintering.
Further, the rubber pattern in Mold Making step (1) is multichannel conjoined structure, and honeycomb shape, size, hole
Several and honeycomb duct length can arbitrarily increase and decrease according to actual needs.
Further, it is produced and multichannel disjunctor rubber in Mold Making step (2) with hard materials such as perforated steel plates
3. interior outer support disjunctor skeleton structure that evacuated mould matches is 4..
Further, the sealing rubber plug in Mold Making step (3) is 2. conjoined structure, ensure that each position sealing
Continuous sealing.
The beneficial effects of the present invention are: the production method of this ceramic honey comb pipe proposed by the present invention, makes each honeycomb pore
Wall is in cold isostatic press in pressing process, while by the extruding towards the uniform pressure conducted inside green body, to guarantee
The homogeneity of each position density of honeycomb pipe, the production efficiency for solving such large, honeycomb tubular products is low, yield rate is low,
The production problem that at high cost, product quality cannot be guaranteed.
Detailed description of the invention
Fig. 1 is a kind of production method mold longitudinal section main view of large, honeycomb ceramic tube of the present invention, and Fig. 2 is this hair
A kind of bright production method mold cross-sectional plan view of large, honeycomb ceramic tube.The arrangement mode of pore and quantity can in figure
To change according to actual needs, the such product mold structure designing and manufacturing method of major embodiment of the present invention.
Specific embodiment
