Q: The principle of a graphite missile: When graphite sticks to point wires, numerous circuits are formed, but they are short circuited.So the circuit was broken.

Q: Graphite powder what is the difference?: Lead chemical symbol Pb, belonging to heavy metals, toxic to the human body, excessive intake of lead will accumulate in the body, the body can not take the initiative to discharge, a great harm.

Q: The difference between silicone and silicone?: Characteristics of silica gel:Silica gel is a one component, room temperature vulcanized liquid rubber. Once exposed to air, the silane monomer condensed, forming a network structure, crosslinked, unable to melt and dissolve, elastic, rubbery, and adhesive. The thermal conductivity is slightly higher than the general rubber, but compared with the thermal grease is much lower, and once cured, it is difficult to separate the adhesive objects, generally can only be used in graphics cards, memory radiator. Mainly used in silicone adhesive low-end card heat sink and the main chip, bonding and particles, particles of the memory memory and radiator. The high-end products are generally used to dissipate heat with grease, and then use the clip fins fixed on the substrate, but it will increase the cost of. The radiating fins are fixed in the low-end graphics chip and good memory particles, and the heat sink in the low-end graphics cards generally are relatively small, so the use of silicone adhesive is common; and high-end graphics and the CPU heat is far greater than the general low-end graphics chip and memory particle heat generation, and the head is relatively CPU so, the grease with radiator and clip form. If used on the CPU will cause overheating, and it is difficult to remove the heat sink, pull down, it may directly damage the CPU or CPU socket. And if you pull down the silicone adhesive cards, heat sink, it is possible to display the chip from the PCB pull down. From this point, we can see who has a better heat conduction effect.

Q: Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it: The graphite bomb is real, but the main is to destroy the enemy power plant and other fixed objects, the damaged helicopter is unlikely, because the rocket explosion scope is limited, that not what eggs with graphite. It's better to use a bullet warhead than a graphite warhead.

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: What if the key is inserted in the hole and can not be drawn out?: Don't use the strength to Jin qiao. You can also pour cold water into the hole. It's very useful

Q: Crystal graphite of graphite powder: The crystal structure of highly structured pyrolytic graphite, La above 2000Nm, from low temperature to high temperature, the thermal conductivity changes with the temperature is bell shaped, see Figure 1, figure 2.

Q: Is the graphite powder produced with sulphuric acid?: The production process of graphite powder is divided into the mechanical method and chemical method, in order to become the graphite graphite powder, graphite powder mill must pass to pieces of different specifications, mesh, some kinds of graphite powder

Q: What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand: General additives accounted for 0.1-0.5 of the original sand weight. Different demand, of course, the proportion is not the same, there is no fixed number.

Q: Phosphoric acid, two aluminium hydride, with graphite powder and mud: Some of the key wavelengths off the chemical bond are shown below. The C-N bond is easiest to break, and the C-H bond is the hardest. You can also see that ultraviolet radiation can cause many chemical bonds to break. The activation wave length of some polymers is listed below. The data in the following table show that different polymers have different maximum damage wavelengths, and often the maximum damage wavelength is called the maximum activation wavelength. At this particular wavelength of light, the polymer can crack at the fastest rate.
