Q:Will the brush grease not short-circuit the commutator?

The brush of motor is usually made of pure graphite electrode, electrochemical graphite electrode and metal fossil ink electrode material. Because it contains graphite, it has conductive effect on the one hand

Q:Synthesis techniques of carbon nanotubes

The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.

Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?

High purity graphite is said to produce graphite electrode, ash is very low, generally below 10 million.

Q:What are the factors that affect the electrode wear rate of machine tools?

Effect of peak pulse current on electrode wear. The peak current has a great influence on electrode wear, but the curves are very different due to the different materials of the electrode and the workpiece. In the copper electrode machining steel, general peak current, electrode loss is also large, but also have a great relationship with the pulse width, so in practice, we should choose different peak current of different area according to the data processing technology of power supply and discharge pulse width, can make the processing speed is high, and the electrode loss small.

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:Where is the graphite electrode scrap?

Atoms, ions, and electrons collide with each other in strong oscillatory motion to produce more electrons and ions.

Q:Why should supercapacitors use graphite as electrode material?

Because the graphite material's electrochemical stability is good, can let the super capacitor withstand the higher monomer voltage. The electrode is not easy to wear out.

Q:Use of graphite in steelmaking

Application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.

Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?

Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining

Q:What are the losses in graphite electrode?

In EDM, discharge principle is to remove the workpiece material by using the tool and the workpiece anode spark discharge explosion, spark discharge is bidirectional, not only will the workpiece removal part, forming processing, will cause some loss of electrode. Electrode loss is one of the main causes of machining errors in machining, and is an important technical parameter affecting the accuracy and quality of EDM
