Q:Does the pencil core go into the baby's face to keep the skin tight?

If there were no broken ends to stay inside and squeeze a little bit of blood out, the problem would not be serious. If you have broken ends, you'd better go to the hospital.

Q:Use of carburizing agents

In the smelting process, due to improper ingredients or improper loading and excessive decarburization, the carbon content in the steel sometimes does not meet the requirements of the top stage. The commonly used carburizing agents include carburized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting medium and high carbon steel in converter, the oil containing little impurity is used, and Jiaozuo is used as carburizing agent. For BOF steelmaking using recarburizer requirement is high to low fixed carbon, ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities, and dry, clean, moderate size.

Q:What is the ratio of the coated sand to the graphite powder?

Or change the sand species, change the high refractoriness sand species, this cost is relatively large.

Q:Graphite powder what is the difference?

Lead chemical symbol Pb, belonging to heavy metals, toxic to the human body, excessive intake of lead will accumulate in the body, the body can not take the initiative to discharge, a great harm.

Q:What solvent can be used to dissolve Teflon?

PTFE is not dissolved after Teflon, it is impossible to mix with graphite powder this thing.

Q:Graphite powder made of graphite oxide, how much weight gain?

The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5.

Q:What is the use of flake graphite in making flake graphite powder?

Better for corrosion protection coatings, fire retardant coatings and conductive coatings.

Q:Is the graphite electrode broken like graphite, fossil oil, coke and graphite powder?

Graphite electrode pieces in different data definition of graphite scrap is different, some data and literature of the graphite particles are called not great pieces of graphite (such as graphite) and some say that graphite products have a certain size, into a block of graphite broken, we are here to say Shi Mosui is second, often called as the graphite block. The production of graphite from graphite products, graphitization and machining process. Graphite waste used as an additive and as a conductive material in the steelmaking and casting industries.

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:Why should the lubrication of automobile leaf springs be made of graphite grease?

Graphite grease is a kind of graphite grease made from inorganic thickener, condensed ester, synthetic oil, and refined with superfine graphite powder, no oxidation, corrosion resistance and other additives.
