What is graphite products? What are the characteristics of graphite products? What graphite products can be made from ordinary graphite? let me tell you one by one.
Graphite products are made of synthetic graphite and natural graphite according to the properties of the graphite.
The characteristics of graphite products have are as following:
1).Graphite products have excellent adsorption. The open space structure of carbon has excellent adsorption, so carbon is often used as adsorption material for the adsorption of water, odor, toxic substances, etc..
2).Graphite products have excellent thermal conductivity, fast heat transfer, uniform heating, fuel saving.
3).Graphite products have the abilities of chemical stability and corrosion resistance. Graphite has excellent chemical stability at room temperature, without any corrosion of acid, alkali and organic solvent. Thus, even if the long-term use of graphite products and its wastage is very small.
4).Graphite products with anti oxidation effect and strong reduction effect.
5).Graphite products are environmental protection, no radioactive pollution, high temperature resistance.
Ordinary graphite products can be produced by ordinary graphite :
1).Conductive material: Graphite in the electrical industry are widely used to electrode, carbon brush, carbon rod, carbon tubes, mercury rectifier cathode and graphite gaskets, telephone parts, the coating of TV picture tube and so on.
2).Wear-resistant and lubrication materials: graphite is often used as a lubricant in the machinery industry. Many equipment for conveying corrosive medium, the widespread adoption of graphite materials made of piston ring, the sealing ring and the bearing, they do not need to add lubricating oil when they are running, aquadag graphite is the good lubricant for metal processing .
3).The corrosion resistant material: graphite has good chemical stability. It has corrosion resistance, good thermal conductivity and low permeability characteristics after special processing of graphite, so it is widely used in production of heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment.
4).Casting, foundry, pressure die and high-temperature metallurgy material: due to the small expansion coefficient of the graphite and the capability of rapid cooling and rapid heating changes. The moulding die and boat made of graphite materials are usually used to product the hard alloy and other powder metallurgy process. Crucible for silicon crystal growth, zone refining vessel, bracket, fixture and induction heater etc.. In addition, graphite can also be used for vacuum smelting as graphite heat insulation board and base, high temperature resistance furnace tube, rod, plate, grid and other components.
5).The anti fouling material: graphite can prevent fouling in the boiler, and the unit test indicates that the amount of graphite powder (about 59 a ton of water) is added to the water to prevent fouling on the boiler surface. In addition, graphite is coated on metal chimney, roof, bridge, pipeline can be anti-corrosion and rust.
