- Q:Will the brush grease not short-circuit the commutator?
- Specifically: between motor brush and collector plus grease is redundant, but it is very harmful, fat instead will not play the role of good lubrication, it will destroy the good lubrication brush itself, not superfluous".
- Q:Can Naiduo high temperature graphite
- The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..
- Q:The difference between graphite electrode and graphite rod
- Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.
- Q:Classification of graphite electrodes
- A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.
- Q:What do carbon products include?
- High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q:What is the striking electrode in the die making? Where is the technical point?
- Technology of EDM should master the characteristics of electric discharge between tool electrode and workpiece is not in direct contact, but there is a gap, the gap is generally between 0.05~0.3mm, sometimes may reach 0.5mm or more, full of fluid, processing by high voltage pulsed discharge, the discharge of corrosion the workpiece.
- Q:I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- Is this principle. Graphite is a layer, each layer, each carbon is SP2 hybrid, and around three carbon connected, finally, between layer and layer formed delocalized covalent bond, making layer and layer can be connected. However, the delocalized covalent bond is not very stable, in attracting Yang Jizheng charge, delocalized covalent bond will certain destruction, the force between the graphite layer and the layer becomes small or not, so as to open.The black stuff is graphite
- Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
- China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.
- Q:What are pyrolytic graphite electrodes used for?
- (1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.
- Q:Carbon graphite electrode and what is the difference?
- Graphite electrode is a mixture of natural graphite and petroleum coke and asphalt coke. After being treated by high temperature graphitization, the material is composed of graphite;
