1. Production technics:
Product characteristics and application scope: high content of fixed carbon, low sulfur content, stable carburetion effect and high absorptivity of carbon, best degree of graphitization, improve the nucleation of melted iron, it is mainly applied to the carburetion of various electro-smelting cast steel and iron casting.
2. Recommended method of application:
adjust carbon content while blending, add it into the place below the middle part of the electric furnace along with metal furnace charge when melting down liquid steel(iron) in accordance with the requirement of carbon content, absorptivity of carbon could reach 90%-95%, during strong carburant residue shall not appear, otherwise it is easy to be wrapped in the non-waste residue and influence the absorption of carbon thereby.

- Q:The processing technology of graphite powder is different, will the price of graphite powder be different?
- The production area of graphite powder is different: graphite ore is widely distributed at home and abroad, and the carbon content of ore and other factors also affect 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:Can graphite powder be used in lithium batteries?
- Qingdao Huatai graphite more than 20 years experience in the production of graphite powder to tell you that graphite powder can be used in lithium batteries.
- Q:What if the key is inserted in the hole and can not be drawn out?
- The end of the pencil is made of graphite, and the graphite powder can be used as lubricant for the machine running under high temperature, and the pencil core can be made. Add some pencil powder to the keyhole. Try to lubricate the inside of the keyhole. Try it!
- Q:Know how the colloidal graphite powder comes in
- There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.
- Q:The axis and drum can use graphite powder lubrication
- Of course, you can not use graphite lubrication, it will damage your parts. You can still use grease or butter, and the middle axle is better with butter
- Q:Is graphite powder conductive?
- The bottom current may be the internal resistance of the battery is too large, in addition to graphite reasons, the contact state of battery cathode and graphite copper check, graphite powder, no contact measurement, the conductivity of no experience, resistance measurement of graphite column can be compared (with the current large and small current comparison test),
- Q:What companies use graphite powder, graphite particles, graphite ball, silicon carbide alloy ball?
- Refractory industry, because of the high temperature resistance of graphite and silicon, it will be applied in refractory industry.
- 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:Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
- The other is to install an electrostatic eliminator when the material falls into the vibrating screen. When the material is dropped, the powder static electricity is removed and the mass will not be assembled again.
