As everyone knows, the graphite has a sheet crystal structure and good lubrication performance like molybdenum sulfide and MOS2. And it also has good electrical conductivity, thermal conductivity, wear resistance, pressure resistance, temperature resistance (temperature can be up to 450 degrees C) and chemical stability of memory and characteristics, so the graphite are widely used to manufacture various lubricants in the machinery industry. Used as the graphite lubricant, it mainly makes the graphite particles distributed uniformly in the form stable colloidal matter in water, oil or other medium, it can directly use inunction, dip coating or spraying way to add to the parts which need the lubrication, it can also be added to a variety of lubricants. It is in…
The graphite electrode has the advantages of easy processing, high metal removal rate in EDM, as well as a small loss of graphite. Therefore, more and more mold factory abandon the use of copper electrode and choose graphite electrode. So, what are the advantages of graphite? 1).The proportion of graphite is copper 1/5, the weight of the same volume of graphite is 5 times lighter than that of copper. the large electrodes made from copper are too heavy, in the long running, it is very unfavorable to the accuracy of the machine tool spindle on the EDM. But graphite is opposite and in safe handling! 2).The graphite can have a very high processing speed, the general speed of the processing…
Graphite has good resistance to high temperature, electrical conductivity, thermal conductivity, lubricity, and chemical stability, widely used in metallurgical, mechanical, environmental, chemical, fire resistance, electronics, medical, military and aerospace fields, is becoming more and more important in the national economy, is essential to modern industry and high and new advanced technology development the important non-metallic materials, and trace impurities have a great effect on the performance of graphite products. The higher the carbon content of graphite, the better the performance of the functional materials will be. Because there are very few impurities in high purity graphite, and the general analytical method of instrumental analysis can not be detected accurately, this method needs to be improved. The analysis of trace impurities…
