- Q: Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
- Dust explosion condition(1) flammable dusts are suspended in the air at proper concentration to form dust clouds which are often called;(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction. Generally believed that the explosive dust as long as the conditions (1) and conditions (2), it means that there are possible signs of the accident.
- Q: Which shipping company can pick up the name of graphite? Graphite products are mainly exported to India, Italy and the United states!
- Is mainly for a graphite export of dual-use technology permits other electronic key can not what Beijing permit the electronic key to table is generally 3-5 days of our electronic key you can apply for 2-3 months
- Q: Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!
- Graphite powder, the first thing you should do is broken to a certain number of graphite powder, then add oil glue, is what we often say that the asphalt rubber, but imports of stone glue made less than impurities, suggest you use imported oil glue mixer, stir evenly into the mold machine with hydraulic pressure, hydraulic machine is 3000T this is a general, graphite block grinding pressure type, pressure oil well placed after the glue soak for seven days, and then go to the three or four roasting roasting, can be used, according to your different purposes, different adjustment process.
- Q: How to deal with graphite powder? Anyone recycle it?
- The use is so great that every friend who does plastic business needs it
- 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: Crystal graphite of graphite powder
- At room temperature, lambda A is about 200 times larger than lambda C. As the temperature increases, this ratio decreases, but remains large. Therefore, the thermal conductivity of polycrystalline graphite composed of microcrystalline is controlled by the thermal conductivity of microcrystalline layer lambda a, and lambda C can hardly be considered. The lambda a of natural flake graphite is between 280 and 500W/ (m * K) at room temperature. The ratio of lambda a/ lambda C is between 3~5, so the perfection of crystal is far better than that of high directional pyrolytic graphite.
- Q: What is graphite powder?
- 1) high temperature resistance: Graphite melting point of 3850 + 50 degrees, boiling point is 4250 degrees, even after the ultra-high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is very small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade.2) conduction and thermal conductivity: the conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Heat conductivity exceeds steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, the graphite becomes hot.3) lubricity: the lubricity of graphite depends on the size of graphite scales. The larger the scale, the smaller the coefficient of friction and the better the lubricity.4) chemical stability: graphite has good chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.5) plasticity: the toughness of graphite is good, but it can be a very thin slice.6) thermal shock resistance: when graphite is used at normal temperature, it can withstand the drastic change of temperature without damaging. When the temperature changes suddenly, the volume of graphite changes little and no cracks occur.
- Q: Graphite powder made of graphite oxide, how much weight gain?
- 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. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
- 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: Refractive index and absorbance of graphite powder
- I have already said, the color change, that change the material inside, you have not had the measured absorbance of the substance determination in you have set the wavelength of the sum of the original material, but a new generation of absorption material and the residual absorbance. The original substance must have been reduced, and its contribution to absorbance is correspondingly reduced, but the newly formed material may have a stronger absorption at this wavelength, so the overall result is an increase in absorbance. If you want to use absorbance analysis, you must select a suitable wavelength so that only the material you wish to measure at this wavelength is absorbed without interference from other substances.
