Q:Use of carburizing agents

The particle size is too fine, easy to burn, too coarse, float on the surface of liquid steel after adding, and it is not easy to be absorbed by steel. The particle size of 0.2-6mm in the induction furnace, the steel and other ferrous metal particles in 1.4-9.5mm high carbon steel, low nitrogen, particle size in 0.5-5mm, and according to the specific needs of the furnace smelting specific types of workpiece so the details of specific judgment and selection.

Q:Distinguish iron powder and graphite powder by chemical method

This problem is very simple, the use of chemical methods to distinguish: there are many ways to give me introduce you to some here, one plus HCl for Fe+HCl=FeCl2+H2, C and HCl reaction, 2: they were put into CuSO4 solution, can replace the red metal iron, whereas C

Q:Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?

At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents;

Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.

In industrial enterprises, when the dust concentration in the dust producing area is within the scope of explosion, dust explosions can occur if contact with an open flame is waiting for the fire source

Q:Is the graphite powder poisonous?

Qingdao Huatai graphite for you to answer, graphite powder itself is no poison, graphite powder is powder, a long time in the graphite powder prone to pneumoconiosis and other occupational diseases, work should bring masks, ventilation conditions, eat more fungus and so on to prevent,

Q:What's the conductivity of graphite powder, silver powder?

These two values show that the resistivity of silver is small, so the conductivity of silver powder is better

Q:Main ingredients of graphite powder?

These impurities often appear in quartz, pyrite, carbonate and other minerals.

Q:Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand

But the conductive carbon black in plastic system can achieve better quality with less graphite is because in polymer systems, factors of conducting conductivity in addition to the conductive powder itself, but also with the distribution of conductive particles in the polymer related. The same quality of the carbon black and graphite carbon black, due to a smaller proportion, occupy a large volume fraction of the polymer, is conducive to the formation of conductive network, which was better than the effect of conductive filler graphite.But in the high aggregation state, the conductivity of graphite aggregate is much better than that of carbon black. The good conductive electrode material is made of graphite instead of carbon black.

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

Image, graphite powder, like flour, in order to make bar shaped, such as face and water, you need to add something.

Q:Crystal graphite of graphite powder

The crystal structure of highly structured pyrolytic graphite, La above 2000Nm, from low temperature to high temperature, the thermal conductivity changes with the temperature is bell shaped, see Figure 1, figure 2.
