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:Classification of graphite powders

Grand powder (anti sealing grease) properties and uses: high temperature of 3000 degrees Celsius, high pressure 40KG, used for ships, aircraft, locomotives, automobiles, engineering machinery and all kinds of large-scale oil, chemical industry, electrical machinery and metal binding surface, the flange seal parts and anti sticking.Special graphite coating: paint, water-based graphite conductive graphite coatings, deposited graphite coating, graphite coating, graphite coating inside and outside the drawing, coating, glass coating, lubrication of graphite graphite TV and special coatings, non metal materials, nano materials, production process design. Deal with all kinds of anti-corrosion equipment, undertake all kinds of anti-corrosion equipment processing. Various varieties, specifications complete, the implementation of the "People's Republic of China national standards.". Special machinery design and manufacture all kinds of fine chemical equipment, various grinding machines and formula process.

Q:Is battery capacitor powder dangerous?

Graphite is very soft, creamy feel. It has excellent electrical conductivity. Color steel gray or gray, with metallic luster, with lubrication, easy dyes, chemical stability, heat conductivity, good heat resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, due to its small crystal plasticity, good adhesion, so it does not belong to the dangerous goods!

Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?

When the ambient temperature is low, the potassium hydroxide solution is used at a density of 1.19 to 1.21 (15 DEG C).

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

Casting molding mainly used for special silica sand, zircon sand, magnesia and chromite, pearl sand, graphite sand. Casting powder mainly used in coatings, such as: quartz powder, bauxite powder, zircon powder, graphite powder, etc.

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

Personally think: black carbon on the human body, and the extent of the time has a lot to do with. On the human body caused by short-term damage is limited to a certain extent, can be restored (but the inhaled particles are difficult to be excreted); over the long term, great harm to the human body, but also can not be restored. Heavy inhalation of carbon black dust can at least cause carbon black, dust, and lung disease (occupational disease, pneumoconiosis). Included in the pneumoconiosis in China: silicosis, coal worker's pneumoconiosis pneumoconiosis, graphite, carbon black pneumoconiosis, asbestosis, talc, mica, cement pneumoconiosis pneumoconiosis pneumoconiosis, Potter's pneumoconiosis, aluminum pneumoconiosis, welders' pneumoconiosis, graphite pneumoconiosis etc.)! At present, the world's lack of treatment for pneumoconiosis, suffering from pneumoconiosis equivalent to sentenced to death. The number of pneumoconiosis patients in our country is equal to that of pneumoconiosis patients in other parts of the world. Please pay more attention to it and don't inhale any more

Q:Is the graphite powder produced with sulphuric acid?

The production process of graphite powder is divided into the mechanical method and chemical method, in order to become the graphite graphite powder, graphite powder mill must pass to pieces of different specifications, mesh, some kinds of graphite powder

Q:How can the antirust graphite powder used for locks be operated? Where is it painted?

In the process of switching the door locks on weekdays, the best holding handle lock tongue into the lock, closed the door and then let go, don't bang the door, otherwise it will reduce the service life. Do not use wet cloth to wipe the lock and handle, because some metallic lock will rust; lock alloy material will lose coating worn, beautiful appearance.

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.

Q:How much is one graphite used as electrode?

Product Name: graphite electrode, graphite crucible, graphite plate, graphite tile, graphite powderProduct price: 7000 yuan / tonCompany location: Hebei, Handan
