Q:Where are the graphite powders sold?

From graphite powder production, packaging, sale, delivery one-stop service, eliminating the agent and intermediary price differentials, and direct profits to customers.

Q:The processing technology of graphite powder is different, will the price of graphite powder be different?

The transportation cost of graphite powder is different: in different areas, transportation costs and prices are different, which will lead to more change in the price of graphite powder.

Q:Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.

Read millivolt values and sample height, calculated according to the formula P =UA/IL type resistivity. The resistivity of the conductor is in P, Omega - M; L for voltage measurement distance between two probes for m; A for the conductor cross-sectional area, m2; U, the voltage between two probes for the determination of voltage V; I the strength of the current flowing through the conductors, the resistivity of A. graphite is (8 ~ 13) * 10-6 (/m), high - low note inside magazines. For reference only!

Q:Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you

A magnet attracts iron powder... Take the same volume of two substances, respectively, in the hands of weighing, the heavier iron powder

Q:Can graphite powder be used for concrete?

Generally, stone toner is not used for concrete.There is no standard used or not used in this respect.Individuals believe that in order to form black concrete, it is feasible to add a small amount of graphite powder to concrete, but it should be proved to be in conformity with concrete standards and shall be reported to the business management department for approval. In other cases, even graphite powder can be used for concrete and is also a waste of resources. From the point of view of resource saving, graphite powder should not be used in concrete.

Q:Influence and protection of graphite dust on electrical equipment in workshop

Graphite powder is very easy to cause static electricity and short circuit, especially for the weak point, the graphite powder must be filtered out, or the electric distribution box is placed separately.

Q:Is the graphite powder produced with sulphuric acid?

Graphite powder can smash through physical production method, also can be produced by sulfuric acid and other chemical methods, according to different types of graphite powder, the production process is not the same, I hope there is help for you, hope to adopt, thank you.

Q:Can graphite be made directly from graphite powder? How about the effect?

Because of the low activity of graphite powder, a kind of binder is needed.

Q:Why should the lubrication of automobile leaf springs be made of graphite grease?

Graphite grease is a kind of graphite grease made from inorganic thickener, condensed ester, synthetic oil, and refined with superfine graphite powder, no oxidation, corrosion resistance and other additives.

Q:What binder does the graphite powder form with?

The commonly used asphalt in the industry is used as binder, and graphite powder and asphalt are mixed and pressed to form. It is also necessary to heat, roast and graphitized the asphalt in the graphite blocks to obtain certain heat conducting, conductive or other uses of Shi Mobang.
