Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?

Device for electrolytic reaction. The electrolysis bath comprises a tank, an anode and a cathode, the majority of diaphragm separates the anode chamber and a cathode chamber. According to the different electrolyte aqueous solution electrolysis, molten salt electrolytic cell and nonaqueous solution electrolysis. When three kinds of direct current through the electrolytic cell, the anode oxidation the reaction solution and at the interface in the cathode and the electrolyte interface reaction, to produce the required products. To optimize the design of electrolytic cell structure, reasonable selection of electrode and diaphragm material is the key to improve the current efficiency, decrease cell voltage and energy saving.

Q:The future of graphene

Sensor domain. Graphene due to its unique two-dimensional structure is widely used in sensor, has the advantages of small size, large surface area, high sensitivity, fast response time, fast and easy electron transfer protein immobilization and maintained its activity and other characteristics, can improve the performance of sensor. Mainly used in the production of gas, biological molecules, enzymes and DNA electrochemical sensors. Singapore Nanyang Technology University developed a graphene light sensor sensitivity is 1000 times the ordinary sensor; the Rensselaer Polytechnic Institute developed performance than the existing commercial gas sensor cheap graphene sponge sensor.

Q:Classification of graphite electrodes

A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace.

Q:Why graphite can be used as conductive material?

Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at the temperature and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing when good lubricant.

Q:Why use platinum ferroalloy instead of iron as electrode?

General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.

Q:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?

This is not a good estimate of the sheet graphite resistance after 5mm

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:How to solve the problem of graphite electrode being crushed during electrolysis

This graphite electrode is so true because it causes gas to expand and disintegrateTantalum electrodes can be solved and not expensive

Q:What's the use of carbon?

Oxidation resistant coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking.

Q:What are pyrolytic graphite electrodes used for?

The weight is lighter: the density of graphite is only 1/5 of copper. When the large electrode is used for EDM, it can effectively reduce the burden of machine tools (EDM). It is more suitable for applications on large moulds.
