Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?

Anode material of nickel cadmium batteries is a mixture of nickel hydroxide and graphite as anode material, sponge cadmium and cadmium oxide powder powder, the electrolyte is usually sodium hydroxide or potassium hydroxide solution. When ambient temperature is high, use a sodium hydroxide solution with a density of 1.17 to 1.19 (15 C).

Q:The difference between silicone and silicone?

Silica gel and grease are helpful to system cooling material, the difference is that the silica gel with good thermal performance and insulation, and will not lose its stickiness pale yellow translucent glue at higher temperatures, mainly used in the surface of the heat radiating sheet sticking device; and the grease is not sticky, is a liquid emulsion or cream like, its role is to fill the gap between the chip and the heat sink, improve the efficiency of heat conduction.

Q:Why does an electromagnetic point timer not prick a needle and use toner paper?

Needles can increase friction! Will increase the error!

Q:The graphite powder production process and the graphite production process are introduced briefly Graphite powder production process, graphite production process, detailed technical parameters where?

According to the size of the crushed or broken material, the mill can be divided into coarse crusher, middle crusher, fine mill and superfine mill.

Q:The graphite powder can replace thermal grease?

Graphite is non-toxic, but graphite powder is harmful to human body; and graphite is used mostly in conductive products (common battery).

Q:Can graphite powder be used as a carburizing agent?

It is OK to use a machine that processes fish food with high carbon content,

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

That's simple. Just use a magnet. Iron is stronger than graphite. Test the conductivity, or measure the density, because the two substances are black and the color doesn't work. I wish you progress in your studies

Q:Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?

In general, the average particle size of graphite powder is less than 10 m, you can call ultrafine powder toner, in fact, more than the use of ultrafine particles of toner, you can see Qingdao Huatai graphite, I hope to help you.

Q:Why can graphite powder conduct electricity?

Graphite and diamond, carbon 60, carbon nanotubes are carbon elements, they are allotropes.Laixi, Shandong Province, is one of the important graphite producing areas in China. The proved graphite reserves are 6 million 871 thousand and 100 tons, and the reserves are 6 million 399 thousand and 300 tonsSoft, black, gray, greasy, dirty 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.

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.
