ADVANTAGES
High Purity Natural Flake Graphite Powder
OUR Flake graphite has many advantages:
1. perfect crystallization
2. thin flake
3. good flexibility,
4. excellent chemical andphysical properties,
5. superior conductivity,
6. self-lubricity
7. resistance to temperature, corrosion and hot shock.
- Q:How can the antirust graphite powder used for locks be operated? Where is it painted?
- When the lock is in use, a small stone powder or pencil powder can be put in the lock core slot for regular (half a year or year) or when the key is not inserted smoothly, so as to ensure that the key is inserted and inserted smoothly. But avoid adding any other oils to lubricate to prevent grease sticking to the spring, causing the lock to rotate and not open.
- 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: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:Can I use super fine stone powder in grease or lubricating oil?
- Not really. It depends on the amount of graphite powder. If the graphite powder forms a continuous through zone, it can be considered a conductor.You can use lubricating oil, preferably not with graphite, which will cause the sliding rheostat to fail
- Q:What are the hazards of inhalation of graphite dust?
- The main pathological change was two lung was black, the whole lung has isolated or clusters of small black nodules around the bronchioles and small blood vessels, irregular nodules; around focal emphysema, pleural thickening and adhesion. X - ray was mainly manifested in increased lung markings, with fine mesh fabric and fine nodular shadows, coarse mesh progression increased, often associated with emphysema, China has listed as the occupation scope of carbon black pneumoconiosis disease.
- Q:Can graphite powder be used as a carburizing agent?
- Basically can be, but to look at your purity, if many impurities can not be used if the carburant is a general term, is all can increase the carbon content of the material referred to a molten iron, graphite powder is then dust too much, when the operation is not clean, too small it is easy to burn and water oxidation, not good,
- Q:Where are the graphite powders sold?
- The graphite powder only local graphite mineral resources have now sold, graphite powder mainly sold through e-commerce channels from the Internet, Huatai graphite powder sales network covering more than 20 cities and counties, we are more than 20 years of graphite powder manufacturers
- 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: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:Influence and protection of graphite dust on electrical equipment in workshop
- Graphite powder is very easy to cause static electricity and short circuit, especially for the weak point, the graphite powder must be filtered out, or the electric distribution box is placed separately.
