Q:Use of carburizing agents
The particle size is too fine, easy to burn, too coarse, float on the surface of liquid steel after adding, and it is not easy to be absorbed by steel. The particle size of 0.2-6mm in the induction furnace, the steel and other ferrous metal particles in 1.4-9.5mm high carbon steel, low nitrogen, particle size in 0.5-5mm, and according to the specific needs of the furnace smelting specific types of workpiece so the details of specific judgment and selection.
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: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:What graphite powder made of graphite products, high hardness?! Wear-resisting! Good moisture! It can be made into graphite products at 100-200 degrees high temperature
Graphite powder and resin mixing, molding, and then "high temperature" curing made graphite products, but the intensity of what will not be very high. Usually graphite products are not prepared directly with graphite powder, but with various kinds of coke, such as asphalt coke, petroleum coke, etc. the graphite products prepared by this method have high strength.
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:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?
The solution of potassium hydroxide at a density of 1.25~1.27 (15 DEG C) is used at temperatures below -15. For the purpose of taking into account the low temperature performance and the charge holding capacity, the sealed nickel cadmium battery adopts an aqueous solution of potassium hydroxide with a density of 1.40 (15 DEG C). In order to increase the capacity and cycle life of battery, usually adding lithium hydroxide amount in the electrolyte (per litre of electrolyte and 15~20g).
Q:Is the graphite powder poisonous?
Qingdao Huatai graphite for you to answer, graphite powder itself is no poison, graphite powder is powder, a long time in the graphite powder prone to pneumoconiosis and other occupational diseases, work should bring masks, ventilation conditions, eat more fungus and so on to prevent,
Q:What are the hazards of inhalation of graphite dust?
It must be harmful to human beings! Look at the dictionary of carbon black dust lung disease Description: black carbon pneumoconiosis: long-term inhalation of carbon black dust caused by pneumoconiosis. Carbon black is mainly the quality of easy flying carbon. Although the production has been closed and automated, the phenomenon of dust flying still exists. Therefore, workers who produce and use carbon black may have black carbon pneumoconiosis, the shortest length of onset is 15 years, the longest can be more than 25 years, the clinical symptoms are mild, and the progress is slow, and generally does not affect the ability to work.
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:Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
Electrostatic earthing or electrostatic eliminator. In fact, there is a certain conductive graphite powder is very fine, but so long as the electrostatic would slightly have great effect, give you two ways, one is the good grounding conductor can be static vibration sieve, go through a grounding wire guide;
