30000Mt per year

graphite powder

Particle size: 32mesh to 5000mesh,

carbon content: 80-99.99%.

 

Property:

Scale is thin,flexible and crystallized completely with excellent physical and chemical properties such as good temperature resistance,self-lubrication,conductibility,heat resistance,shake resistance,and erosion resistance.

 

Use:

Widely applied to high quality fire resistance material and coating of metallurgy industry,hot working material stabilizer of military industry,lead of light industry,carbon brush of electrical industry,electrode of battery industry,and catalyzer and additive of fertilizer industry.After further process,scale graphite can be made into the following high-tech products such as graphite colloidal graphite,graphite compacting material and composite material,graphite products,and graphite anti-friction additive,which are becoming important nonmetal mineral materials in every industry.

Q:How to measure the conductivity of powdered graphite?
Voltammetric measurement of resistanceMethods: using precision small range measurement of electricity meter, multimeter resistance or contrast test you can use small bulbs, according to the brightness of his conductivity, if the bulb is more bright, that resistance is lower.
Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
Method two: Ignite (ignite in oxygen bottle)Iron sparks, release a lot of heat, and generation of black powderAluminum burns violently, gives off dazzling white light, emits a large amount of heat, and simultaneously produces white solidThe graphite powder is formed to clarify the turbid water of the lime waterMethod three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectively
Q:Influence and protection of graphite dust on electrical equipment in workshop
The graphite dust in the workshop is conductive, and the adhesion to the electric apparatus will affect the electrical insulation and lead to accidents. So we need to have the electrical box of graphite dust workshop to closed treatment, to prevent dust into the electrical cabinet.
Q:Can you tin to latex paint
Yes, it's better to paint with antirust paint and putty,
Q:Can graphite powder be used as a carburizing agent?
Basically can be, but to look at your purity, if many impurities can not be used if the carburant is a general term, is all can increase the carbon content of the material referred to a molten iron, graphite powder is then dust too much, when the operation is not clean, too small it is easy to burn and water oxidation, not good,
Q:What graphite powder made of graphite products, high hardness?! Wear-resisting! Good moisture! It can be made into graphite products at 100-200 degrees high temperature
100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.
Q:How does graphite powder look good or bad?
High quality graphite powder has high carbon content, superior performance, good quality and wide application range. This is the reason why the quality of graphite powder is higher than other graphite powder.
Q:Is the graphite electrode broken like graphite, fossil oil, coke and graphite powder?
The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
Q:Is graphite powder conductive?
Yes, graphite has electrical conductivity
Q:Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!
Graphite powder, the first thing you should do is broken to a certain number of graphite powder, then add oil glue, is what we often say that the asphalt rubber, but imports of stone glue made less than impurities, suggest you use imported oil glue mixer, stir evenly into the mold machine with hydraulic pressure, hydraulic machine is 3000T this is a general, graphite block grinding pressure type, pressure oil well placed after the glue soak for seven days, and then go to the three or four roasting roasting, can be used, according to your different purposes, different adjustment process.
