- Q:Is graphite powder dangerous?
- Will pour into the dry drying workshop, drying after bagging, namely ordinary graphite powder, the carbon content of the finished product is 90%.x0d on average use making pencil graphite electrode, battery, cable lubricant morphological characteristics of a dark metallic luster and opaque fine flake graphite solid. Very soft, creamy sense.
- Q:Does graphite allow lubrication of rusted doors?
- Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.
- Q:Distinguish iron powder and graphite powder by chemical method
- 1., add dilute hydrochloric acid or dilute sulfuric acid, the bubble is iron powder2. heating, iron powder is black, graphite is ignited in the air3. is mixed with copper oxide, and heating, plus graphite can be generated to clarify the muddy lime water turbidity CO2, iron powder No.
- Q:Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?
- Under heating, the graphite powder is more easily oxidized by acid. At high temperature, it can react with many metals to produce metal carbides, which can smelt metals at high temperature
- Q:Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!
- As for the equipment used, there are many, and the price is also high, light an oil press will not be possible, there are dipping pot, baking furnace, etc., at least tens of millions of it.
- Q:What graphite powder made of graphite products, high hardness?! Wear-resisting！ Good moisture! It can be made into graphite products at 100-200 degrees high temperature
- Graphite powder and resin mixing, molding, and then "high temperature" curing made graphite products, but the intensity of what will not be very high. Usually graphite products are not prepared directly with graphite powder, but with various kinds of coke, such as asphalt coke, petroleum coke, etc. the graphite products prepared by this method have high strength.
- Q:How can graphite paper be made? Can graphite powder be solidified without brittleness?
- Process for the preparation of graphite paper: high carbon flake graphite, graphite by chemical processing into acid (also known as graphite oxide or expandable graphite), in high temperature 960 to 980 DEG C for a few seconds, the level of the graphite lattice moment along the C axis expansion, a fiber floc type vermicular graphite. The expanded graphite is very soft, the roller for the rolling forming, expanded graphite and flexible graphite sheet or foil sheet.
- Q:Graphite powder made of graphite oxide, how much weight gain?
- The official name of graphite oxide is graphite oxide, or "graphite acid". It is a compound composed of carbon, hydrogen and oxygen elements with different mass ratio. Oxidized graphite can be prepared by treating graphite with a strong oxidizing agent. Of the products obtained, the highest degree of oxidation is a ratio of carbon to oxygen, between 2.1 and 2.9 yellow solid, and still retains the layered structure of graphite, but the structure becomes more complex.
- Q:How can the clinker graphite powder be dissolved in water?
- To achieve this purpose many methods; the titanate coupling agent and silane coupling agent is used in simple water dispersion system of the surface modification, hydrophilic group will make Shi Mofen (film) dispersed in water while stirring under shear stress.
- Q:How to measure the iron content in graphite powder?
- Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.
