What is a graphite copper sleeve
time2017/11/28
Graphite copper sleeve solid lubricant usually accounts for 20 - 30% of friction, lubrication in principle and lubricant brand of copper in the process of covering graphite shaft and friction sliding surface, the friction part of the transfer of the graphite particles, on the shaft, forming a layer of solid lubricant, avoid directly to the diaphragm shaft and wear. The properties of the combined metal and alloy are superior to non-metallic materials, and the complementarity of their milling metals, that is, the high load capacity, and their own properties of the lubricating milling materials. So it's especially suitable for less, come on, high temperature, high load, or water and environment.
Graphite copper sleeve deck copper also known as copper and graphite lubricant, the friction of the metal surface on the deck in the specified order, hole size, and the lubricant with solid lubricant of solid lubricant graphite or molybdenum sulfide etc. product attributes, general lubrication friction and lubrication principle of the surface is on the shaft and friction the sliding friction surface of graphite particles, part of the transfer, on the shaft, forming a layer of solid lubricant, avoid directly to the diaphragm and shaft wear.
The properties of such metal and alloy combination of graphite and copper bushing are non-metallic materials, and their complementarity metals for milling are high load capacity, and have their own properties of lubricating milling materials. It is especially suitable for all less, come on, high temperature, high load, or water and environment.
Graphite copper sleeve lubricants and resistance of the copper alloy property, the use of lubricating oil in the process, no need to maintain. Products are widely used for intermittent movement, or load balance, such as car production lines, water tanks, work accidents, machinery and other doors / plastics. According to the conditions of use, different types of copper alloys can be provided. The main components of the column, the properties of graphite and graphite, the common technical characteristics, the graphite production of different graphite: 1, the high strength temperature: graphite is the most known material, and it is the most resistant to high temperature. His fusion point is 50 degrees, and the boiling point is high dada. The curve is at the lowest temperature at 70 degrees centigrade - 10, graphite, and weight loss of 0.8% graphite. As a result of the graphite copper sleeve, the temperature of the high strength graphite is very prominent. 2, have the special heat shock and heat shock performance: graphite, that is to say, in the major change of temperature coefficient, thermal expansion, so it has good thermal stability, and when temperature and heat, cold and no cracks. 3, conductivity and heat: graphite has good thermal conductivity and conductivity. Compared with the general, the conductivity of the thermal conductive material is very high. 4 times the stainless steel, this is 2 times as high as steel carbon, generally no metal 100 times. 4: properties, lubricating oil lubricated graphite is similar to molybdenum disulfide, the friction coefficient is less than 0.1. Its characteristics and lubricants and skin size variables, larger scale, better smaller friction coefficient, lubrication. The normal temperature of chemical stability of graphite copper sleeve: a good chemical stability, graphite can resist corroded acid, alkali, organic solvent. Second, the diameter of the stone around the production enterprise, as my length. It is widely used in the industry of metal industry, chemical industry, electricity, machinery and so on. Three, provided the products and packaging of graphite: our company agreed to the special requirements of the drawings processing and packaging in the box of wood. The addition of lubricating oil to the column components is mainly graphite, graphite material suitable for lubricating graphite column. It is best to immerse the lubricating oil in graphite column for a period of time.
Graphite copper sleeve this combination of metal and alloy performance advantages of non-metallic materials, its milling complementarity, that is, with the high capacity of the metal. The copper on deck is also known as graphite lubricant. The copper and friction metal surfaces on deck are suitable for ordered holes, and the lubricants of products such as graphite or molybdenum sulfide are solid lubricants. At present, copper graphite on deck is widely used in metallurgy, machinery, engineering machinery, ship, locomotive and mining equipment support, materials, mould, machinery and equipment, textile machinery, gas turbine low and high speed and light load, on other occasions.
