Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?
Graphite is chemically stable (inert), to eliminate it used two methods: one is under the condition of high temperature combustion has sufficient oxygen to remove (heating in a muffle furnace effects are poor), certainly not with the glass bottle; two with hot concentrated sulfuric acid, concentrated nitric acid oxidation to remove heat, if not heating your glass bottle this method, also difficult.
Q:Where are the graphite powders sold?
From graphite powder production, packaging, sale, delivery one-stop service, eliminating the agent and intermediary price differentials, and direct profits to customers.
Q:What is the simple test method for graphite powder used in casting?
Mainly depends on its carbon content, hand stick a little bit on the white paper uniform, if there is a clear scratch is graphite powder
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:Can you tin to latex paint
Can not brush metal thermal expansion and contraction principle is very strong, or how long it will fall off, really want to brush with a small nail unless many small eyes in atoms in the metal, and then dust coat paint brush
Q:How does graphite powder look good or bad?
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. 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?
Dust produced in the process of production of some factories and mines, especially the dust produced in the processing of some organic matters, will explode and burn under certain conditions.(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction.Such as effective ventilation and biological film, dust suppression technology, integrated dust suppression technology, dust removal measures, smoking and fire operations are prohibited. A pressure relief valve or other device is arranged in the outer shell of the equipment, and an explosion containment system is adopted. For factories with dust explosion hazards, the design must be strictly carried out according to the technical grade of explosion protection, and ventilation and dust removal systems shall be installed separately. Often wet cleaning workshop floor and equipment, to prevent dust flying and gathering. Ensure that the system has a good airtight, if necessary, in airtight containers or pipes in the flammable dust filled with nitrogen, carbon dioxide and other gases, in order to reduce the content of oxygen, dust suppression explosion.
Q:Does graphite allow lubrication of rusted doors?
Into the rusty iron graphite powder can play the role of lubrication, graphite powder can open the door locks rust.
Q:Does the pencil core go into the baby's face to keep the skin tight?
One possible problem is that even if there is no breakage, but there may be residual graphite powder cartridge inside, more so, good after the wound will leave behind a black spot (a little like the indistinct).
Q:Graphite powder made of graphite oxide, how much weight gain?
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.
