Antioxidant treatment method for battery dedicated graphite

The antioxidant treatment process of battery -specific graphite includes material preparation, weight, impregnation liquid preparation, impregnated electrode treatment and dry treatment. After graphite electrode processing, it can be processed into various specifications of graphite electrode products. The processed graphite electrode is the same as the unsolvioing graphite electrode. Compared with graphite electrodes, it has the characteristics of smooth surface and good conductivity. The intensity of mechanical design can increase by 50-60%, the pore rate gradually decreases by 10-15%, and the consumption of electrode material can be reduced by 20-25%. Electrical consumption can be reduced by 20-25%.The anti -oxidant treatment of battery -specific graphite has the attributes as follows:(1) Preparation material weighing: weigh the graphite electrode, provide qualified processing materials;(2) Preparation and heating of penetrating solution: The composition of the impregnation solutio

It is critical to properly clean up graphite molds

Like other objects, graphite molds must be cleaned up after a long -term application. This is also a key factor in carrying out maintenance of graphite molds, and after cleaning up, the next manufacturing can be carried out immediately. As a result, the cleaning of graphite molds is very critical.If you want to achieve good practical effects and improve work effectiveness, proper operation steps are also crucial. During the entire process of cleaning the graphite mold, professional equipment maintenance management is created in the connection between the requirements and the actual operation. In order to complete the cost benefits, you must pay more attention when cleaning up. Especially for the different positions of graphite molds, the selected cleaning method is also likely to have a difference.Properly grasp the cleaning method of graphite molds and operate in accordance with the actual operation, which can increase the use period of the machine and equipment at a very large level

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Isostatic pressing graphite

Isostatic pressing graphite is a new product developed internationally in the past 50 years, closely linked to today's high-tech industry. It is an irreplaceable material for manufacturing single crystal furnaces, metal continuous casting graphite crystallizers, graphite electrodes for electrical discharge machining, and is also an excellent material for manufacturing rocket nozzles, graphite reactors, deceleration materials, and reflection materials. Its structure is fine and dense, the roasting process requires a particularly slow speed, and the temperature inside the furnace needs to be very uniform. This process takes about 1-2 months. The preparation process of isostatic pressing graphite includes filling the raw material powder into the mold, compacting the powder through high-frequency electromagnetic vibration, sealing and vacuuming, discharging the air between the powder particles, placing it in a high-pressure container containing liquid medium for pressure pressing, and fin

How to use expansion graphite

1. Protective useExpansion graphite can be used as protective materials, which can be used to protect metal and other damaged objects, such as circuit boards and steel. Because expansion graphite can expand 10 times, it can effectively block the flames and make these objects from burning with flames.2. InsulationExpansion graphite can also be used as insulation materials, because it has good thermal resistance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing the loss of heat, thereby playing the role of heat preservation.3. Filtering useExpansion graphite can also be used as filtering materials, because it has adsorption and can be used to adsorb toxic substances, such as pollutants used in water treatment, which can effectively remove pollutants in water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement useExpansion graphite can also be used as r

Let's take a look at the use of battery -specific graphite in industrial applications

Battery -specific graphite has good chemical stability. The specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low penetration. Therefore, it is widely used in making heat exchangers, reaction tanks, condenser, combustion tower, absorbing tower, absorbing tower , Cooler, heater, filter, and pump equipment, are widely used in industrial departments such as petrochemical, wet metallurgical, acid -base production, synthetic fiber, papermaking, etc., which can save a large number of metal materials.It is a material for casting, casting, suppression, and high temperature metallurgy. Because of its low heat expansion coefficient, it is resistant to cold and hot, it can be used as a casting mold for glassware. After the graphite is used, the black metal can get accurate size, smooth surface, high finished product rate Casting, can be used without processing or machining, saving a lot of metals. In the powder metallurgical process that p

Classification of graphite blocks

Classification of graphite blocks of graphite block classification of graphite blocksThe crushing of graphite blocks can be divided into three items, do you know?Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm.Middle crushing: This also refers to the granular block of graphite blocks that is further broken until the granularity necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Essence (or grinding): It is the following powders to grind some graphite raw materials to 0.15mm or 0.075mm particle size. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushi
