Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
Any object that is crushed will have a surface energy (internal energy), but the temperature will not increase, so the specific heat will become largerFuel burns because its energy is already full (reaching a point of fire)When the object reaches the ignition point, internal energy = (ignition +273.15) * specific heat capacity
Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?
The solution of potassium hydroxide at a density of 1.25~1.27 (15 DEG C) is used at temperatures below -15. For the purpose of taking into account the low temperature performance and the charge holding capacity, the sealed nickel cadmium battery adopts an aqueous solution of potassium hydroxide with a density of 1.40 (15 DEG C). In order to increase the capacity and cycle life of battery, usually adding lithium hydroxide amount in the electrolyte (per litre of electrolyte and 15~20g).
Q:Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?
Ultrafine toner is a thermal conductive function, because ultrafine toner is processed from natural graphite, which inherits the characteristics of natural graphite conduction and heat conduction.
Q:Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.
A cylinder is inserted in the pipe, and the cross section of the pipe is slightly smaller than the inner diameter of the sample tube. The lower cylinder is fixed on the base of the instrument, and the upper cylinder can move up and down in the tube as a prop to pressurize the sample. The sample is located in the insulating casing on the cylinder between the positive and negative pole and galvanometer millivoltmeter are respectively connected to the drum two cylinder, rotary measuring height, driven by the leading screw rod lifting rod to balance, balance level, sample by 3.92MPa pressure, then switch on the current, the current adjustment into the sample to 300mA, then open the switch millivoltmeter,
Q:Are sand and particle powders used for casting quartz sand? Detailed and accurate.
General small foundry is river sand, quartz sand is also useful. But the cost is higher, if the product is not high, the river sand on it. You have a particle powder quartz powder with clay, coal powder, in what way do you use.
Q:Crystal graphite of graphite powder
Pure graphite flake graphite and high directional pyrolytic graphite, which have less defects and larger sizes, can generally be considered as perfect graphite single crystals. Considerable research has been done on the thermal conductivity of such graphite. Under compressive stress, the pyrolytic graphite above 3000K processing, the bulk density is 2.25g/cm, 2.266g/cm is close to the theoretical density of the single crystal, the half width of the diffraction peak (002) show only 0.4 degree angle (mosaic angle), is also very close to the theoretical value of zero. The thermal conductivity of this graphite is shown in table 1. These values are generally considered to represent the corresponding values for single crystal graphite. The thermal conductivity along two principal directions is denoted as lambda a along the layer, and is marked by lambda C along the vertical plane.
Q:Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
The graphite powder will cause an explosion. The production of graphite products in the workshop by means of centralized collection and fire protection to avoid explosion.The combustible dust explosion, dust explosion limits in encountered heat (fire or high temperature), flame spread instantly throughout the mixing space dust, fast chemical reactions, while releasing large amounts of heat, resulting in high temperature and high pressure, the system of energy into mechanical energy and light and heat radiation, has a strong destructive power. In the dust explosion with aluminum powder, zinc powder, aluminum powder, grinding a variety of plastic powder, organic synthesis of drug intermediates, wheat flour, sugar, wood, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, dust and other plant fibers to produce production and processing places.
Q:Is oxygen allowed in the oxygen pipe?
The so-called oxygen pipeline, which depends on the medical or edible, or industrial oxygen pipeline. If it is industrial, a little graphite is possible, but the proportion can not be too large
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:Can graphite be made directly from graphite powder? How about the effect?
Because of the low activity of graphite powder, a kind of binder is needed.
