The difference between high purity graphite rod and impregnated graphite rod

Graphite has good high temperature resistance, thermal conductivity, lubrication, chemical stability, plasticity, thermal shock resistance and other excellent properties, has become one of the popular materials, its refined graphite products are also widely used in various industries. Graphite rods are commonly used as electric heaters for high temperature vacuum furnaces, and their Z high operating temperature can reach 3000 degrees Celsius, and they are easy to oxidize.

High-purity graphite is made of high-density, high-strength, high-purity graphite, which is a little more wear-resistant than ordinary graphite, but only relatively wear-resistant. Some graphite products need to be on rotating equipment, which requires super wear resistance, because high-purity graphite will produce dust in the process of repeated friction, so it needs high wear resistance. In fact, pure graphite products themselves are not too wear-resistant, ultra-wear-resistant graphite products are impregnated with graphite, impregnated graphite can be impregnated with different substances according to the needs of different products, commonly used resin impregnated graphite, antimony impregnated graphite, copper impregnated graphite and so on have strong wear resistance, such as impregnated epoxy resin graphite has wear resistance and lubrication characteristics.

The resin impregnated graphite rod is not only wear-resistant, but also lubricated, and the resin impregnated graphite rod can be processed into a variety of lubricating and wear-resistant graphite products, and the processed graphite products are very smooth, and the mirror effect can be achieved in the case of polishing.

Graphite itself is a solid lubricant, but not all graphite is lubricated. At present, most of the graphite used for oil-free self-bearing is carbon arc planer. In fact, the lubrication performance of the carbon arc gouger rod is not very good, just because of the use of graphite materials. Graphite lubrication depends on its scale, the larger the scale. The better the lubrication effect, the better the lubrication effect, so oil-free bearings and self-lubricating copper guide products can wear well.

Carbon arc gouging carbon rod is mainly used to assist shipbuilding, its role is to dissolve and clean the weld, open the groove. For example, if quality problems with existing defects are found after welding the weld, carbon rods are used for dissolution and purification. This process creates high temperatures that melt the iron and blow it away through compressed air. This shipyard is mainly used for repairing welds. The model specification is 355 mm long, and its diameter is usually negative 0.15-0.2, because it is also a layer of metal on the surface, so it is negative tolerance, while the carbon arc plane carbon rod can be removed by hand touch, because the carbon arc plane carbon rod is extruded, its air tightness is very large, the particle size is very soft, and it will fall layer by layer.
