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 battery capacitor powder dangerous?

Graphite is very soft, creamy feel. It has excellent electrical conductivity. Color steel gray or gray, with metallic luster, with lubrication, easy dyes, chemical stability, heat conductivity, good heat resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, due to its small crystal plasticity, good adhesion, so it does not belong to the dangerous goods!

Q:How to deal with graphite powder? Anyone recycle it?

We have a lot of graphite, and now we have it

Q:How to measure the conductivity of powdered graphite?

Some other factors for measuring the resistivity of conductive graphite powderConductivity varies with external factors and is sensitive. The early microphones were made with graphite powder, because the vibration of the voice changed the electrical conductivity between the graphite powders and changed the current to produce analog signals. One can imagine that you need to test his electrical conductivity for the experimental environment.

Q:Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you

First, with a magnet, you can use a magnet, can be sucked into the iron powder.Two, put in the water, floating above the sink in the bottom of the graphite powder, iron powder

Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?

When the ambient temperature is low, the potassium hydroxide solution is used at a density of 1.19 to 1.21 (15 DEG C).

Q:What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?

If it is a long-term work in the environment first, graphite dust masks, the more than 2 eat bananas, like blood. Case said harmful, you can not see any problems with graphite processing. In short, the dust class should pay attention to, and avoid direct inhalation

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:The principle of a graphite missile

The graphite missile contains carbon fibers and is highly conductive. After the explosion of carbon fiber floats attached to the high-voltage lines immediately cause transformer short circuit burned, to destroy the enemy's power to.

Q:How can the antirust graphite powder used for locks be operated? Where is it painted?

When the lock is in use, a small stone powder or pencil powder can be put in the lock core slot for regular (half a year or year) or when the key is not inserted smoothly, so as to ensure that the key is inserted and inserted smoothly. But avoid adding any other oils to lubricate to prevent grease sticking to the spring, causing the lock to rotate and not open.
