Q:Is graphite powder dangerous?

Graphite powder graphite is a kind of battery cathode materials. The process of graphite powder, will after the bursting of the raw ore by car to crush the rock breaking machine, and ball mill by flotation, the flotation of graphite ball mill grinding wet material sending selected, will be selected to dry the wet material bagging machine dry a shower, shower is dry, dry graphite finished product.

Q:The processing technology of graphite powder is different, will the price of graphite powder be different?

The production process of graphite powder is different: graphite powder production process has many, different production process makes the cost of graphite powder increase, so the price of graphite powder has been unstable.

Q:What are the hazards of inhalation of graphite dust?

The main pathological change was two lung was black, the whole lung has isolated or clusters of small black nodules around the bronchioles and small blood vessels, irregular nodules; around focal emphysema, pleural thickening and adhesion. X - ray was mainly manifested in increased lung markings, with fine mesh fabric and fine nodular shadows, coarse mesh progression increased, often associated with emphysema, China has listed as the occupation scope of carbon black pneumoconiosis disease.

Q:Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?

Under heating, the graphite powder is more easily oxidized by acid. At high temperature, it can react with many metals to produce metal carbides, which can smelt metals at high temperature

Q:The axis and drum can use graphite powder lubrication

No, graphite powder is suitable for high temperature environment, and the lubricating effect is better than that of lubricating oil

Q:What's the conductivity of graphite powder, silver powder?

The resistivity of graphite is approximately (8~13) * 10-6.M at room temperature

Q:How to measure the conductivity of powdered graphite?

The conductive effect of graphite powder is an important factor in making conductive products, so it is very important to know the conductivity of graphite powder.Graphite powders have high electrical conductivity. And stone toner conductivity is an important factor in graphite powder conductive products. There are many factors affecting the conductivity of conductive graphite powder, such as the proportion of graphite powder, external pressure, humidity of the environment, humidity and even light.

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

Ordinary graphite powder is also conductive, but only strong and weak

Q:Can you tin to latex paint

Latex paint and self spray paint are not rustproof against iron. The main component of antirust paint is antirust pigment and film forming material. Usually in the name of anti rust paint named, such as: rustproof paint, antirust paint, iron oxide red. If it is divided into four categories: antirust, paint, chemical action, antirust paint, electrochemical action, antirust paint, comprehensive function antirust paint.

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.
