The lubrication of sliced graphite is mainly reflected in two aspects

1. Silver-like Gention-Environmental atmospheric lubricationThe essence of lubrication of sheet -like graphite is its laminar crystal structure. The initial raw materials for preparation of expansion graphite are high -carbon -like graphite. Other chemical reagents such as concentrated sulfuric acid (more than 98%), hydrogen peroxide (more than 28%), and potassium permanganate are industrial -grade reagents. The general steps of preparation are as follows: At the appropriate temperature, add different proportion of hydrogen peroxide solution, natural scales and concentrated sulfuric acid to different programs, react for a certain period of time under continuous stirring, and then wash to neutrality, centrifugal, dehydrated, and dehydration. Dry vacuum at 60 ° C.2. Film graphite-solid lubricant and lubricant additiveThe lubrication performance of slices graphite is also affected by graphite particles. Some research and test results show that whether it is a natural piece of graphite or

Unique chemical properties of industrial graphite products

Graphite is an important mineral resource in the 21st century, and China ranks first in the world in terms of graphite ore reserves. With the improvement of graphite product processing technology, it has been widely used in fields such as chemical engineering, smelting, casting, new materials, molds, aerospace, etc. We often see many chemical properties of graphite products in the industry, such as graphite crucibles, graphite heaters, graphite molds, etc(1) High temperature resistance: In smelting, the melting point of graphite products is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles.(2) Good conductivity and thermal conductivity: The conductivity of graphite products is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exce

How are graphite electrodes consumed in electric furnace steelmaking?

The consumption of graphite electrodes is mainly related to the quality of the electrodes themselves, as well as to steelmaking operations and processes.(1) Electrode end consumption. Its consumption includes the sublimation of graphite material caused by high arc temperature, as well as the loss of chemical reactions between the electrode end and molten steel and slag. The electrode end consumption is also related to whether the electrode is inserted into the molten steel to increase.(2) Oxidation loss on the outer surface of the electrode. In recent years, in order to improve the smelting rate of electric furnaces, oxygen blowing has been widely used, which has led to an increase in electrode oxidation losses. In general, the oxidation loss on the outer circular surface of the electrode accounts for about 50% of the total electrode consumption.(3) Residual loss of electrodes or connectors. A small section of electrode or connector that is continuously used at the connection between
