Q:How do you use graphite powder in copper?

This question is a bit vague, you can say it, is inlaid with copper and graphite, the graphite powder melt into the copper, if it is the former, is easy to do, if it is the latter, it is necessary to copper melting after adding graphite powder, the latter is relatively difficult.

Q:How to measure the conductivity of powdered graphite?

The conductivity of conductive graphite powder was measured by resin methodTo buy some conductive paint resin, add the same amount of conductive graphite powder, and then coated on a board, with digital multimeter to measure its conductivity on the list.

Q:What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand

In addition to improve the refractoriness with graphite, can also add red. It also plays a role in increasing refractoriness and reducing gas output.

Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.

Dust explosion condition(1) flammable dusts are suspended in the air at proper concentration to form dust clouds which are often called;(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction. Generally believed that the explosive dust as long as the conditions (1) and conditions (2), it means that there are possible signs of the accident.

Q:Graphite and graphite in the end is not a matter I would like to know the graphite and graphite

Graphite gum APS two, colloidal or semi - colloidal graphite. (a) colloidal graphite, graphite powder from natural or artificial graphite fine powder in water or other media (e.g., alcohol, mineral oil) colloidal suspensions in the form, and can add a few other products (e.g., tannic acid or ammonia) to be stable. Colloidal graphite is usually semi liquid and is used primarily for lubricating products or for its high electrical conductivity. (two) a semi colloidal graphite (i.e., a colloidal suspension of graphite in water or other medium). Semi crystalline graphite can be used to prepare graphite lubricants or to form graphitized surfaces. This class contains only colloidal or semi colloidal suspensions of graphite with graphite as base material in any medium.

Q:What are the specifications of the graphite powder used for conduction?

Graphite powder itself is conductive, according to purity, particle size, conductivity is also different

Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?

Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.

Q:Is the graphite powder produced with sulphuric acid?

Graphite powder can smash through physical production method, also can be produced by sulfuric acid and other chemical methods, according to different types of graphite powder, the production process is not the same, I hope there is help for you, hope to adopt, thank you.

Q:Can I use super fine stone powder in grease or lubricating oil?

Yes, it can play a role in increasing extreme pressure. But it has little effect on low temperature and high temperature resistance. It can not play the role of total synthesis of molybdenum disulfide high temperature grease.

Q:How much is one graphite used as electrode?

Graphite particles 6800 yuan / ton, graphite fine powder 8000 yuan / ton, you buy 30 yuan / kg is the natural graphite powder? Not made of graphite electrodes. The graphite powder used in the electrode is actually synthetic graphite powder.
