It can be used to indicate the degree of graphitization degree. The difference between the semi graphitic carbon block and the graphite carbon block is that the arrangement of the crystal lattice is different. Graphite carbon block, with easy graphitization coke as raw material, its graphitization temperature should reach 2500 degrees celsius. The former has higher strength and hardness, and the latter has better conductivity and integrity. The utility model is characterized in that the coke is prepared by the use of more easily graphitized coke as raw material, and the heat treatment is carried out at the temperature of 1800 to 2000 DEG C after the raw product is calcined into the graphitization furnace. Which is a kind of high quality high temperature calcined anthracite or graphite fragments more even with all the bits of graphite as aggregate, green products after forming only after calcination (calcination temperature less than 1200 DEG C) is no longer in the graphite furnace heat treatment, the carbon block called semi graphite carbon block. Semi graphite carbon block is divided into two kinds according to the production process. The common cathode carbon block is made from anthracite calcined at 1250 to 1350 DEG C. According to the quality requirements of the products, the raw materials and the process conditions, the cathode carbon blocks in China are classified into 3 categories: common cathode carbon block, semi graphite carbon block and graphite carbon block. Corrosion resistance and good conductivity, good thermal conductivity, high mechanical strength, good thermal shock resistance and strong corrosion resistance. The production of aluminum electrolysis requires high temperature resistance.
The characteristic cathode carbon block acts as a conductor and forms the dual role of the inner lining of the electrolytic cell. The bottom of the electrolytic tank is also called a bottom carbon block. It can make the products with smooth, fine, wear resistance, corrosion resistance, high brightness, not easy to change color and so on.Ĭarbon block made of high quality anthracite, coke and graphite.
The graphite anode plate can be used as the conductive anode in electroplating industry, and it is an ideal material for electroplating.
In electrolysis industry, using graphite anode plate as the anode has a history of more than and 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.Ĭompared with other materials of graphite anode plate has high temperature resistance, good electrical and thermal conductivity, easy machining, good chemical stability, acid and alkali resistance, low ash content for electrolytic solution, preparation of chlorine, caustic soda, salt alkali electrolytic solution preparation application such as graphite anode plate can be used as conductive anode electrolytic salt solution preparation of caustic soda. In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.
