Abstract
The invention discloses a tourmaline lamella sintered on the surface of a honeycomb ceramic passage. 95wt% of submicron tourmaline micropowder and 5wt% of nanoscale sol are subjected to ball milling for 20-24 hours and then mixed and smashed to form slurry with the solid content of 60%-70%, and honeycomb ceramics are dipped in the slurry for 1-2 hours to enable the tourmaline to settle on the inner passage surface of the honeycomb ceramics. The geometric specific surface area can be greatly increased to 800-2000m<2>/m<3>, tourmaline usage is greatly saved, resistance in fluid treatment is greatly reduced, and fine energy saving effect can be achieved.
Description
Technical field
The invention belongs to the stupalith field, relate to the application of a kind of ceramic honey comb material aspect tourmalinite, be specifically related to a kind of ceramic honey comb channel surface sintering tourmalinite thin layer.
Background technology
Since a series of excellent function of tourmalinite comes to light; It is just exploited, is processed, is utilized with the progressive increase rate of annual 10%-20%; But tourmalinite is a kind of in the very rare resource of occurring in nature; As the maximum effect of the next ultimate attainment performance of how minimum tourmalinite consumption, be technical staff author and the business people's common task and the key subjects of industries such as geology, mineral products, material.
Optimize water works with regard to tourmalinite; Still take at present earlier tourmalinite (other raw mineral materialss of adapted 30-70%) to be fired balling-up, be immersed in the mode of activation drinking-water in the water again, this kind mode is a kind of mode of typical high flow rate resource; Because tourmalinite ball and water generation energy transformation and catalytic process only are confined on the thin layer of outer surface of ball; The inner tourmalinite of ball does not play any effect, and uses globe to handle drinking-water, energy transformation can take place, catalytic surface-area is not high; The formed accumulation of isometrical ball of general diameter 5-10mm, its geometric proportion surface-area is 100-200m only
2/ m
3, and current advanced energy conversion device and contact reacts system, its geometric proportion surface-area has reached 800-2000m
2/ m
3, almost be ten times of spheroid.In addition, the resistance of the spherical accumulation system of the heap type convection cell that looses is very big, and when the tourmalinite ball was used for flowing the processing of water system, the water level loss of head of system was bigger, correspondingly will consume more energy.
Summary of the invention
In order to overcome the deficiency of prior art, the invention provides a kind of ceramic honey comb channel surface sintering tourmalinite thin layer that can practice thrift the tourmalinite consumption significantly.
With 95%wt submicron tourmalinite micro mist and 5wt nano level colloidal sol mixed through ball milling 20-24 hour, pulverize process the mud that solid content is 60%-70% after; Ceramic honey comb impregnated in the mud 1-2 hour; Make tourmalinite mud be deposited on the internal surface of ceramic honey comb; The control time of immersion of ceramic honey comb in the tourmalinite slurry and the moisture content concentration of tourmalinite slurry can also be controlled the thickness of tourmaline intermediate layer on the honeycomb inner hole wall easily.
Adopt ceramic honey comb channel surface sintering tourmalinite thin layer of the present invention, can greatly increase the geometric proportion surface-area, reach 800-2000m
2/ m
3, practiced thrift the tourmalinite consumption significantly, resistance reduces significantly during treat fluid, has good energy-saving effect.
Description of drawings
Accompanying drawing 1 is that the ceramic honey comb dipping is inhaled the slurry synoptic diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing ceramic honey comb channel surface sintering tourmalinite thin layer of the present invention is set forth in detail; Thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
The honeycomb type carrier is a kind of having continuously and single structure, and by the load that many parallel channels constitute, there are square, regular hexagon, equilateral triangle, annular etc. in the cross section of its parallel channels, on the general xsect 80-400 hole/inch is arranged
2, wall thickness 0.1-0.6mm, geometric proportion surface-area 800-2000m
2/ m
3, no matter be the green compact of ceramic honey comb or burnt ripe goods that its material all has the apparent porosity up to 10%-50%, can go up any slurry through pickling process absorption.With 95wt submicron tourmalinite micro mist and 5wt nano level colloidal sol mixed through ball milling 20-24 hour, pulverize process the mud that solid content is 60%-70% after; Ceramic honey comb impregnated in the mud 1-2 hour; Make tourmalinite mud be deposited on the internal surface of ceramic honey comb; The control time of immersion of ceramic honey comb in the tourmalinite slurry and the moisture content concentration of tourmalinite slurry can also be controlled the thickness of tourmaline intermediate layer on the honeycomb inner hole wall easily.
When sintering; The tourmalinite thin layer forms the tourmalinite matter thin layers of ceramic except that solid state reaction takes place self, also can mutual physical-chemical reaction take place with the ceramic honey comb body, comprises each other solid state reaction and mass transfer; Fusion and flow expansion; Form a kind of interpenetrative middle layer at the interface of two-phase, the two is combined securely, mechanical stress, rapid heat cycle stress, chemical erosion etc. all can not make them separate.Tourmaline ceramic layer on the honeycomb internal surface; In the thermal shock repeatedly of 200-20 ℃ of water, not ftractureing comes off, and is difficult to scrape the tourmalinite thin layer with sharp cutter, in the HCl solution of the NaOH of PH≤8 solution and PH>=5; Deposited three months under the room temperature; The phenomenon that the tourmalinite thin layer does not dissolve, comes off, 700 ℃ of hot environment held 1 hour, the tourmalinite thin layer do not melt, do not ftracture, shrinking away from theshell not.
The aperture, individual hole of honeycomb parallel channels 2-3mm only using on the effect, owing to when current pass through honeycomb, can all be cut into 2 * 2m
2Or thinner current; In the narrow electric field that is formed by tourmalinite, by successive polarization gradually, receive better activation effect, the fluid resistance of ball shut-down system than the big 100-1000 of honeycomb doubly; So use favose tourmalinite matter pottery, also can make the user obtain good energy-saving effect.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
