Abstract
An electrically conductive graphite concrete for electric heating, industrial heating, drying and shielding electromagnetic waves is prepared from cement, graphite, sand, fly ash, boiler cinder, volcanic ash, broken rock and ceramic granulas. Its advantages include low cost, high heat efficiency, long service life, high chemical and thermal stability, and no menvironmental pollution.
Description
The present invention relates to a kind of electrically conductive graphite concrete 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 graphite concrete is that cement, sand, graphite, stopping composition and an amount of water mix.
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.Content of graphite in the electrically conductive graphite concrete and concrete resistance 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 conducting concrete 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 graphite concrete has been compared tangible advantage with existing various thermo electric materials, as: resistance wire, Si-Mo rod exist that thermo-efficiency is low, work-ing life weak point, complex process, cost height, heating-surface area shortcoming such as little.There are shortcomings such as complex process, cost height, heating-surface area be little in the PTC pottery.Conducting concrete described in the patent publication No. CN1130604A is an electro-conductive material with the carbon fiber, and its weight accounts for weight concrete 0.05% to 5%, because carbon fiber price height, and the market circulation amount is few, has improved the cost of conducting concrete, is not easy again to be extensive use of.The electro-conductive material of electrically conductive graphite concrete is a graphite, and cost is low, the starting material wide material sources, can heat more in large area and the shielding electromagnetic wave radiation, and the thermo-efficiency height, good endurance, long service life, easy to use, pollution-free.Can in building operation, be used to build by laying bricks or stones the conductivity ceramics brick, build common building body of wall, ground by laying bricks or stones.Aspect heating, industrial heating, drying and electromagnetic wave shielding, use.
Claims (3)
1. electrically conductive graphite concrete, its raw material consists of cement, graphite, packing material (flyash, slag, volcanic ash, rock powder, sand).By weight: graphite is between 5% to 40%.Cement accounts between 30% to 80%.Packing material accounts for 5% to 50%.
2. according to a kind of or any one combination of the described packing material of claim 1 by sand, flyash, slag, volcanic ash, crushed rocks, broken ceramic particle.
3. use at aspects such as heating buildings, industrial heating, drying and electromagnetic shieldings.
