Q:Method for identifying iron powder, aluminium powder and graphite powder

1. aluminum powder is silver, black substance attract rest with a magnet that attracted iron, not be attracted to the graphite2. Add equal mass, such as concentration of dilute hydrochloric acid, the gas is fast aluminum powder, slow iron, and do not produce gas is graphite.

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

Q:Why can graphite powder conduct electricity?

Dense crystalline graphite is also called massive graphite. These crystals are crystalline and visible to the naked eye. Particle diameter greater than 0.1 mm. The crystals are arranged in a dense and blocky structure. The graphite is characterized by a very high grade, general carbon content is 60 ~ 65%, sometimes up to 80 ~ 98%, but its plasticity and unctuousness as fine flake graphite.

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:Know how the colloidal graphite powder comes in

Smaller graphite particles are uniformly dispersed in water, oil, and other organic solvents, forming a black, sticky suspension. Also called colloidal graphite or graphite milk.Colloidal graphite was first obtained in nineteenth Century by Acheson. The raw material is natural graphite or artificial graphite.

Q:Are sand and particle powders used for casting quartz sand? Detailed and accurate.

Not necessarily. It depends on what product you make to determine what sand or powder you use

Q:Can you tin to latex paint

Can not brush metal thermal expansion and contraction principle is very strong, or how long it will fall off, really want to brush with a small nail unless many small eyes in atoms in the metal, and then dust coat paint brush

Q:What is the industry standard of graphite powder coating for casting?

One is purity, that is, the size of impurities, the smaller the better.

Q:Whether the ordinary graphite powder is sprinkled on the electronic instrument can lead to the malfunction of the instrument

Graphite powder mainly high pure graphite, graphite powder, nano graphite powder, each is toner has a specific map, if abused, graphite powder will have a certain impact on the letter together, Ruida professional build thermal field | graphite graphite graphite | | isostatic graphite graphite mold, hope this the answer can help to you

Q:How can graphite paper be made? Can graphite powder be solidified without brittleness?

Single layer graphite paper is all graphite products, excluding other materials
