Q:What's the conductivity of graphite powder, silver powder?
These two values show that the resistivity of silver is small, so the conductivity of silver powder is better
Q:Why can graphite powder conduct electricity?
Graphite is a crystalline mineral of carbonaceous elements. Its crystalline framework is hexagonal layered structure. The distance between each network layer is 3.40, and the distance between the carbon atoms in the same network layer is 1.42A. Of the six Fang system with a complete lamellar cleavage. The cleavage surface is mainly based on molecular bonds, and has weaker molecular attraction, so its natural floatability is very good.
Q:Why does an electromagnetic point timer not prick a needle and use toner paper?
Needles can increase friction! Will increase the error!
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:What is the ratio of the coated sand to the graphite powder?
In addition to improve the refractoriness with graphite, can also add red. It also plays a role in increasing refractoriness and reducing gas output.
Q:Phosphoric acid, two aluminium hydride, with graphite powder and mud
Sunlight filtered through the atmosphere to achieve visible light and a small amount of ultraviolet light (UV) on the earth's surface. UV light has a wavelength of 295nm and UV light accounts for only 5% of the sun. The energy of light is inversely proportional to the wavelength, and the shorter the wavelength, the higher the energy.
Q:What are the hazards of inhalation of graphite dust?
Personally think: black carbon on the human body, and the extent of the time has a lot to do with. On the human body caused by short-term damage is limited to a certain extent, can be restored (but the inhaled particles are difficult to be excreted); over the long term, great harm to the human body, but also can not be restored. Heavy inhalation of carbon black dust can at least cause carbon black, dust, and lung disease (occupational disease, pneumoconiosis). Included in the pneumoconiosis in China: silicosis, coal worker's pneumoconiosis pneumoconiosis, graphite, carbon black pneumoconiosis, asbestosis, talc, mica, cement pneumoconiosis pneumoconiosis pneumoconiosis, Potter's pneumoconiosis, aluminum pneumoconiosis, welders' pneumoconiosis, graphite pneumoconiosis etc.)! At present, the world's lack of treatment for pneumoconiosis, suffering from pneumoconiosis equivalent to sentenced to death. The number of pneumoconiosis patients in our country is equal to that of pneumoconiosis patients in other parts of the world. Please pay more attention to it and don't inhale any more
Q:How to measure the conductivity of powdered graphite?
Some other factors for measuring the resistivity of conductive graphite powderConductivity varies with external factors and is sensitive. The early microphones were made with graphite powder, because the vibration of the voice changed the electrical conductivity between the graphite powders and changed the current to produce analog signals. One can imagine that you need to test his electrical conductivity for the experimental environment.
Q:How many kinds of lubricating graphite powder can be added to the car engine?
1500, the purpose of graphite powder can be added to the car engine, "anti-static graphite powder 1500 mesh."".Application of graphite powder in cooling system (water tank) and lubrication system (engine oil)Graphite powder is greater than 1000, added to the tank inside, rust off, and scale also fell.
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.
