Q:Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?: Because the metal activity order form sodium potassium calcium magnesium aluminum, zinc and tin lead (hydrogen), mercury copper silver platinum, iron in the front row because of water water hydrogen, ionized hydrogen ions by iron replacement

Q:Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?: Graphite electrodes react with oxygen to form carbon dioxide, soluble in water

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:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: In theory, as long as a certain temperature is reached, any substance can be burned, and the diamond is converted to graphite at 2000~3000 DEG C under anaerobic conditions. That is to say, graphite (flake graphite)

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 are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found: The high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.

Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?: 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q:What kinds of carbon are there?: 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:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?: For example, according to connection of the electrode, which can be divided into two types of unipolar and bipolar type electrolyzer (see photo). The electrode is connected with the DC power supply parallel polarity monopolar electrolyzer, electrodes on both sides of the same, at the same time as anode or cathode. At the same time as the positive and negative electrode bipolar type electrolyzer ends respectively with DC power supply connected, as anode or cathode. The current through the electrode through the electrolysis cell in series, each side of the intermediate electrode as the anode, the other side is the cathode, so it has a bipolar electrode. When the total area at the same time, the current bipolar type electrolyzer is small, high voltage DC power supply, the required investment ratio monopolar, bipolar type filter press used. The general structure, more compact. But easy to leakage and short circuit, slot structure and operation management is more complex than the monopolar type. The monopolar electrolyzer section is generally rectangular or square, cylindrical covers a large, empty The utilization rate is low and the adoption rate is less

Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?: Not alwaysIt depends on the rate of electrolyzed water or the rate at which sodium sulfite is oxidized.

Our products have been sold to Europe, Southeast Asia, South America, India, and other countries and regions. Meanwhile, Our Graphite Electrodes and nipples have already been ISO9001:2000 approved. We will pay attention to product quality and offer you the best price. We hope that we could establish business relationships with all friends on the basis of equality and mutual benefits.
