1. Graphite anode plate
In the electrolytic cell, the level where the current flows into the electrolyte from here is called the graphite anode plate. In the electrolysis industry, the anode is generally made into a plate shape, so it is called the graphite anode plate, which is widely used in electric ferry, wastewater treatment, industrial anticorrosion equipment Or as special materials. In the electrolysis industry, the use of graphite anode plates as anodes has a history of more than 100 years, but the use of metals as anodes has been a matter of recent decades. China's research and application of metal anodes are even later, only in the 1970s Research and experiment on the technology of metal anodes. As far as 2113 anodes in the electrolysis industry are concerned, they have mainly experienced high silver (2%) and low silver (0.5%), namely lead silver alloy, lead silver tin antimony alloy, lead calcium alloy, Lead silver addition nucleating agent alloy and other stages.
Compared with other materials, graphite anode plates have the advantages of high temperature resistance, good electrical and thermal conductivity, easy mechanical processing, good chemical stability, acid and alkali corrosion resistance, low ash content, etc.; used in electrolytic aqueous solutions, preparation of chlorine, caustic soda, electrolysis Salt solution is used to prepare alkali; for example, graphite anode plate can be used as electrolysis salt solution to prepare conductive anode of caustic soda. Application Graphite anode plate can be used as a conductive anode in the electroplating industry and is an ideal material for various electroplating; making electroplated products have the advantages of smooth, delicate, wear-resistant, corrosion-resistant, high brightness, and not easy to change color.
2. graphite cathode carbon plate
Carbon block made from high-quality anthracite, coke, graphite and other raw materials. Used as the cathode of an aluminum electrolytic cell. It is built on the bottom of the electrolytic cell, also known as the bottom carbon block. Characteristics The cathode carbon block plays the dual role of conducting electricity and forming the lining of the electrolytic cell. Aluminum electrolytic production requires high temperature resistance of the cathode carbon block. The characteristics of resistance to molten salt erosion, good electrical conductivity, good thermal conductivity, high mechanical strength, good thermal shock resistance and strong resistance to sodium erosion are conducive to energy saving and longevity of aluminum electrolytic production. The types of cathode carbon blocks are based on the requirements of 5261 for the quality of the products, the raw materials selected and the process conditions. China basically divides the cathode carbon blocks into three categories: ordinary cathode carbon blocks, semi-graphite carbon blocks and graphite carbon blocks. Ordinary cathode carbon block uses anthracite calcined at 1250～1350℃ as its main raw material. Semi-graphite carbon blocks are divided into two types according to different production processes.
One is to use high-quality high-temperature electrical calcination of anthracite coal, or more graphite fragments or even all graphite fragments as aggregate. The green products after molding are only roasted (roasting temperature does not exceed 1200 ℃) and no longer go into graphitization Furnace heat treatment, this carbon block is called semi-graphite carbon block.
Another kind of easily graphitized coke is used as aggregate. After roasting the raw product, it enters the graphitization furnace for heat treatment at a temperature of 1800～2000℃. This kind of carbon block is called semi-graphite (chemical) carbon block.
The former has higher strength and hardness, while the latter has better conductivity and integrity. Graphite carbon block is made of easy graphitized coke and its graphitization temperature should reach about 2500℃. The difference between a semi-graphite carbon block and a graphite carbon block is the degree of orderly arrangement of the product lattice, that is, the degree of graphitization. The degree of graphitization can be expressed by the resistivity of the product. The lattice of the graphite carbon block is basically in an orderly arrangement, and the resistivity is less than 15μΩm; the graphitization degree of the semi-graphite carbon block is low or only partially graphitized, and the resistivity is 15 to 165345μΩm. The process is represented by the heat treatment temperature. The maximum heat treatment temperature of the semi-graphite carbon block is about 2000°C, and the graphitization temperature of the graphite carbon block is 2500-2800°C. Ordinary cathode carbon block, resistivity 50～60μΩm. The graphitized cathode is a conductive material used in the cathode of an aluminum electrolytic cell, and represents the development direction of the electrolytic aluminum industry. With the technological progress and development of the electrolytic aluminum industry, the electrolytic cell is developing in the direction of large capacity above 300KVA, and the requirements for cathode materials are higher. The main advantages of graphitized cathodes are to strengthen the current, improve the current efficiency, achieve the purpose of increasing production and energy saving, and to stabilize the operation of the electrolytic cell. The larger the tank type, the more stable the running effect is, the more obvious the current efficiency is. The unit production capacity is increased by 10-15%, and the energy saving per ton of aluminum is more than 600KWh. The graphitized cathode aluminum electrolysis cell is one of the materials that the country preferentially promotes and develops in the electrolytic aluminum industry due to its obvious energy-saving, consumption-reducing and emission-reducing effects.
