Abstract
The present invention relates to conductive ceramics, which is suitable for electric heating warming, industrial heating, drying and electromagnetic wave shielding for buildings. The conductive ceramics are composite materials composed of graphite, clay, fly ash, furnace slag, volcanic ash, rock powder and sand, and have the advantages of low production cost, high thermal efficiency, long service life, high chemical stability, high thermal stability, good electromagnetic wave shielding effect, no environmental pollution and convenient operation. When formed into the integration with building structures (walls, ground), the present invention has the advantages that the conductive ceramics provide large heat dissipation area and shielding area, do not singly occupy indoor space, etc.
Description
The present invention relates to a kind of electrically conductive graphiee ceramics material and its making method.
A kind of heats is good, production cost is low in order to seek, long service life, good chemical stability and thermostability, thermo-efficiency height, save energy, electric heating material pollution-free, easy to use are arranged.Simultaneously, widespread use along with computer, wireless telecommunications system, electromagenetic wave radiation when computer uses is divulged a secret easily, cableless communication make lives on the people in the very strong environment of electromagenetic wave radiation, press for a kind of can protection computer radiation divulge a secret and purify personal lifestyle spatial shielding material, in order to solve the needs of this two aspect, the spy finishes the present invention.
Electrically conductive graphiee ceramics is that clay, graphite and an amount of water are mixed into uniform pug through compacting composite molding, airing, form by the kiln high-temperature firing.
Graphite as electro-conductive material has good heat-resistance, and chemical stability is strong, can be not in use, chemical transformation takes place when particularly contacting with other alkaline material of construction, influence conductive effect and work-ing life.The content of graphite in the electrically conductive graphiee ceramics and the resistance of material are inversely proportional to, and content high resistivity more is more little.
General electrically heated heating element, when certain power, the surface-area of electric heating body (area of dissipation) is big more, the ability of heat exchange is big more, the electrically conductive graphiee ceramics heating evenly, and is in construction, easy to use as material of construction, constitute one with wall, the ground of buildings, do not occupy separately and use the space, and can use by larger area, improved heat exchange level, the thermo-efficiency height reaches better heating effect.
Electrically conductive graphiee ceramics has been compared tangible advantage with existing various thermo electric materials, as: there are shortcomings such as thermo-efficiency is low, work-ing life is short, complete processing is complicated, cost is high, heating-surface area is little in resistance wire, Si-Mo rod, PTC pottery.The license notification number is 2073415 direet-heating type conduction infrared radiation ceramic, uses the height ratio radiative material, has improved cost, has limited use range.The outstanding feature one of electrically conductive graphiee ceramics is to adopt cheap raw material, and raw material sources are extensive, can be made into different shape for building brick, watt the cost of material is low, the 2nd, can utilize the structure of building as heating member to greatest extent; Adopt big area, the design philosophy of mild heat heating, part is filled in heat exchange, and the heat utilization efficiency height needn't be emphasized the thermal emissivity rate of material.The good endurance of material, long service life, easy to use, pollution-free.Can be in widespread use aspect heating, industrial heating, drying and the electromagnetic wave shielding of building.Brought new functions of use for wall, the ground of buildings.
Claims (3)
1, a kind of preparation method of conducting ceramic material, its material consists of clay, graphite, flyash, slag, volcanic ash, rock powder, sand.By weight: graphite accounts between 1% to 30%.Between the clay comprises 50% to 99%.Flyash, slag, volcanic ash, rock powder, sand account for 0 to 40% altogether.
The preparation method:
With clay, graphite is main raw material, adopt the particulate composite methods, be mixed into uniform pug with an amount of water, be pressed into the blank that needs with mould, or with pug and the stacked composite molding of matrix stupalith, airing, be fired into composite conductive ceramic through kiln.
2, according to claim 1, the formation of matrix stupalith is that any one combination by clay or clay and flyash, slag, volcanic ash, rock powder, sand is as complex matrix.
3,, use at aspects such as heating buildings, industry heating and electromagnetic shieldings according to claim 1.
