Q:The principle of a graphite missile
The graphite missile contains carbon fibers and is highly conductive. After the explosion of carbon fiber floats attached to the high-voltage lines immediately cause transformer short circuit burned, to destroy the enemy's power to.
Q:Why should the lubrication of automobile leaf springs be made of graphite grease?
This ultra high temperature grease in high temperature above 200 DEG when the base oil volatilize slowly, will be attached to the graphite solid lubrication lubrication is formed on the surface of graphite, itself is a kind of solid lubricant for heavy load / load impact or damp / high temperature friction parts and bearing lubrication under the pollution of the environment, to provide maximum anti rust corrosion protection
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:Classification of graphite powders
Grand powder (anti sealing grease) properties and uses: high temperature of 3000 degrees Celsius, high pressure 40KG, used for ships, aircraft, locomotives, automobiles, engineering machinery and all kinds of large-scale oil, chemical industry, electrical machinery and metal binding surface, the flange seal parts and anti sticking.Special graphite coating: paint, water-based graphite conductive graphite coatings, deposited graphite coating, graphite coating, graphite coating inside and outside the drawing, coating, glass coating, lubrication of graphite graphite TV and special coatings, non metal materials, nano materials, production process design. Deal with all kinds of anti-corrosion equipment, undertake all kinds of anti-corrosion equipment processing. Various varieties, specifications complete, the implementation of the "People's Republic of China national standards.". Special machinery design and manufacture all kinds of fine chemical equipment, various grinding machines and formula process.
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:How do you use graphite powder in copper?
It is to drill holes on the copper block and pour the graphite into the hole to ensure that the stone toner can not run out and play the role of oil-free lubrication
Q:Can graphite powder be used for concrete?
The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. 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.
Q:Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
Electrostatic earthing or electrostatic eliminator. In fact, there is a certain conductive graphite powder is very fine, but so long as the electrostatic would slightly have great effect, give you two ways, one is the good grounding conductor can be static vibration sieve, go through a grounding wire guide;
Q:For thermal grease skills, the more detailed the better
But this is not possible, the metal lid heat sink and CPU looks smooth, but with a magnifying glass, you can see many holes in metal surface concave stripes and irregular tunnel, lead contact surface with many gaps, these gaps are impeding heat dissipation, thermal grease is liquid, can fill the gaps. Improved radiating surface contact, the heat dissipating effect than when there is no good thermal grease. But if the thermal grease is too thick, it will become a film on the contact surface of the middle, but hindered the direct contact of metal, worse than not coated with thermal grease.
Q:Is graphite powder conductive?
Qingdao Huatai graphite powder solution for you is a conductive graphite powder, graphite powder for non-metallic mineral matters, graphite powder has good conductivity, high temperature resistance, lubrication, thermal properties, graphite powder used in industry is very broad, conductive graphite powder can be made of conductive coating, battery the production of materials, conductive composite materials,
