Q:What solvent can be used to dissolve Teflon?
Market suspension of PTFE fine powder. It can be mixed directly with graphite powder without dissolving. It can press molding and sinter products.
Q:How to identify iron powder and graphite powder in a simple way?
Iron powder can be attracted by magnet, graphite powder can not; iron powder can react with acid, graphite powder can not wait, optional take first magnet attract, and then drip acid or hand touch method to identify two substances;
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:Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
The graphite powder will cause an explosion. The production of graphite products in the workshop by means of centralized collection and fire protection to avoid explosion.The combustible dust explosion, dust explosion limits in encountered heat (fire or high temperature), flame spread instantly throughout the mixing space dust, fast chemical reactions, while releasing large amounts of heat, resulting in high temperature and high pressure, the system of energy into mechanical energy and light and heat radiation, has a strong destructive power. In the dust explosion with aluminum powder, zinc powder, aluminum powder, grinding a variety of plastic powder, organic synthesis of drug intermediates, wheat flour, sugar, wood, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, dust and other plant fibers to produce production and processing places.
Q:What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?
This is determined by the quality of the graphite powder. Graphite workers in our factory are equipped with masks to prevent dust. (formerly, Shandong, South villa, graphite mine) more than 5000 state-owned enterprises, workers have worked for 20-40 years, and has yet to find too much harm to the body. Pay attention to dust protection measures.
Q:Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!
If the isostatic graphite is made by isostatic pressing equipment, it can be divided into cooling method and hot isostatic pressing method. The machine needs import and it is expensive. The basic is to squeeze into a square or cylindrical powder.
Q:Does graphite allow lubrication of rusted doors?
Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.
Q:What is the industry standard of graphite powder coating for casting?
The two is fine, the finer the better, generally with the "eye" as a unit, that is, sieve stone toner used in the screen, square inch area included in the number of holes, the larger the number the better.
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:Whether the lubricating oil toner is coupled with the conductor?
But with graphite, it will make the metal contact sheet and the whole resistance to form the passage, rheostat can not change the role of resistance. I actually lubricate, that is, with cotton swabs dipped in lubricating oil, and then put a touch on it.
