Q:Thermal conductivity and density of graphite powder
For the same type of graphite, the thermal conductivity increases with increasing density, and Figure 11 shows the relation between the density of HDFG and the density of the same graphite.The heat treatment temperature of polycrystalline graphite is mostly made by roasting the semifinished material by high temperature heat treatment. The higher the heat treatment temperature is, the more perfect the crystallite growth is, the La increases, and the thermal conductivity also increases. With calcined petroleum coke and coal tar pitch, roasting sticks made of extrusion, after different heat treatment (HTT), the value of La are shown in Table 4. The axial thermal conductivity will change with temperature is shown in figure 12. The reciprocal of thermal conductivity 1/ lambda is called thermal resistance. At different temperatures, the relationship between the axial thermal resistance of graphite is shown in Figure 13 and l/La / 1/.
Q:What is the simple test method for graphite powder used in casting?
Mainly depends on its carbon content, hand stick a little bit on the white paper uniform, if there is a clear scratch is graphite powder
Q:Why does an electromagnetic point timer not prick a needle and use toner paper?
With the needle point than the powder paper friction, many experimental results of!
Q:What mask should be used to prevent stone powder?
If long-term without protection is inhaled into the lungs, will lead to a lot of precipitation in the lung, which may induce pneumoconiosis (silicosis disease only); in addition, graphite powder is also easy to stimulate the throat and bronchial, cause allergic reactions (asthma). If proper dust control measures are taken, this kind of disease can be avoided.
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:What binder does the graphite powder form with?
Image, graphite powder, like flour, in order to make bar shaped, such as face and water, you need to add something. Because of the low activity of graphite powder, a kind of binder is needed. Let the graphite powder stick into shape.
Q:How to measure the iron content in graphite powder?
Excessive amounts of dilute sulphuric acid can be used to measure the amount of gas produced, and then the amount of iron is calculated according to the amount of gas.
Q:Is the graphite electrode broken like graphite, fossil oil, coke and graphite powder?
Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.
Q:Why does the temperature rise when the graphite powder is turned on?
But one thing will not change. Graphite powder is one of the best nonmetallic conductive materials. As long as the graphite powder is kept inside the insulating object, it will electrify as a thin line
Q:What is the use of flake graphite in making flake graphite powder?
Better for corrosion protection coatings, fire retardant coatings and conductive coatings.
