Q:How to identify iron powder and graphite powder in a simple way?
Iron powder can be attracted by magnet, graphite powder can not; iron powder can react with acid, graphite powder can not wait, optional take first magnet attract, and then drip acid or hand touch method to identify two substances;
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:How does graphite powder solidify into a lump? What bond is best used?After solidification can be more than 1000 degrees high temperature does not change
There is no binder that can withstand 1000 degrees C. At such a high temperature, any binder has been carbonized and has lost its bond effect, so it is impossible if you want to use the binder to make the graphite powder into pieces
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:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?
Anode material of nickel cadmium batteries is a mixture of nickel hydroxide and graphite as anode material, sponge cadmium and cadmium oxide powder powder, the electrolyte is usually sodium hydroxide or potassium hydroxide solution. When ambient temperature is high, use a sodium hydroxide solution with a density of 1.17 to 1.19 (15 C).
Q:Know how the colloidal graphite powder comes in
There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.
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:Why does the temperature rise when the graphite powder is turned on?
What is the value of resistance, and this value is not an accurate number, because the graphite powder thickness is not the same, used in different materials and environment, graphite powder, resistance value will be different.
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:What if the key is inserted in the hole and can not be drawn out?
This is not a simple question, to the dorm there, there will be someone to help you repair
