Graph

Floating method is a type with less energy consumption and reagent consumption and low cost in the conventional purification method of minerals. Real limited improvement. For scales graphite, multi -segment grinding ore cannot be completely unbuttoned, but it is not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite quality. High carbide graphite with more than 99%must be pure graphite with chemical methods.(1) chloride roasting methodThe low roasting temperature and smaller chlorine gas consumption of chloride roasting method have greatly reduced the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to the treatment of hydrofluoric acid method. Compared with the recovery rate of chloride and roasting method, because the chlorine gas is poisonous and has strong corrosiveness, it requires high requirements for equipment operations. It requires strict requirements. Seal

Factors affecting scales graphite oxidation

Scale graphite has strong heat resistance and good corrosion resistance. It is the main carbon raw material used by carbon -resistant refractory materials, but it will have an oxidation reaction with oxygen at high temperature at high temperature. The following editor introduces the factors that affect the oxidation of scales. The specifics are as follows:1. Carbon oxidation responseHeating graphite in the air, carbon can be directly oxidized by O2 to CO and CO2. When carbon oxidation, CO and CO2 hybrid gases are generated. At low temperatures, it is mainly to balance CO2 and solid graphite. Solid graphite balance. At more than 1000 ° C, almost all of the mixed gas is CO. The oxidation response speed of graphite decreases with the total pressure of the system, but it increases with the rise of temperature.2. The effect of granularity on oxidation temperatureWith the increase of granularity, the temperature of the graphite's significant oxidation starts and the temperature of the oxida

How to clean the graphite board

How to clean up graphite graphite products has high -quality conductivity thermal conductivity, can resist high temperature, analyze good chemical stability. One of the graphite anode boards can be used to use chlorine to use the electrolyte water solution to make, electrolytic salt solution to make it. Alkali can also be used to electroplating a variety of metal composite materials non -metallic material media, which is generally used in chemical enterprises, electronic components and other industries.The following is a detailed description of the appropriate cleaning process:1. Wear work clothing, rain shoes, rubber gloves, safety helmets.2. Prepare sufficient sodium hydroxide solution in advance to clean the graphite anode plate.3. Remove the rear cover of the anode oxidation rod and put it in the graphite cleaning groove for 30 minutes.4. Remove the graphite anode board from the soaking solution and put it on the wooden frame.5. Clear the surface of the graphite anode plate with p

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.

The production process and use of expansion graphite

The expansion graphite is a loose and porous worm -like substance prepared by the procedure of graphite scales through the intervening, washing, drying, and high temperature. When the expansion graphite encounters high temperature, it can instantly swell 150 ~ 300 times in volume, which changes from sheet to worm -shaped, thereby loose structure, porous and bending, expanded surface area, improved surface can be enhanced. In this way, it increases its softness, return elasticity and plasticity.The expansion graphite is widely used, and the main development directions are as follows:1. Granules expand graphite: Small particles expand graphite mainly refer to 300 purposes that can expand graphite, and its expansion volume is 100ml/g. This product is mainly used for flame retardant coatings, and its demand is very large.2. Expansion of the swelling temperature at height: The starting expansion temperature is 290-300 ° C, and the expansion volume is ≥230ml/g. This type of expansion graphi

The difference and connection between graphite and graphene

The main difference between graphite and graphene lies in their structure. Graphite is a two-dimensional material with a hexagonal lattice formed by carbon atoms, and is an allotrope of carbon. And graphene is a type of material composed of carbon atoms in the form of sp ² A two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of hybrid orbitals is a single-layer structure of graphite. Therefore, graphite can be seen as a stacked form of graphene.Graphene has some unique physical and chemical properties, such as excellent conductivity and thermal conductivity, high strength, high toughness, etc., making it have broad application prospects in energy, materials, electronics and other fields. Due to its structure, graphite mainly has excellent lubrication and wear resistance, and is commonly used in the manufacturing of lubricants and wear-resistant materials.Although there are significant differences in structure and properties between graphite and graphene, t

Graphite products manufacturers introduce the use of graphite block on cement back kiln in detail

The concrete flip kiln is the insulation machinery and equipment that conducts actual operation under negative pressure. The sealing situation on both sides is immediately associated to the production of cement clinkers, quality and energy consumption. In the work of improving and improving kiln heads and kiln tails, it is one of the effective ways to flip the high -yield and energy -saving of the kiln chemical plant. However, because the working conditions on both sides of the flip kiln are extremely high, not only the temperature is high, but also has flipping and shaking together. Therefore, the sealing work of the flip kiln chemical plant is both the key and difficult. Graphite block has the inevitable heat resistance characteristics and excellent authenticity characteristics, which can achieve a good regulation of flip kiln sealing. Therefore, in China, the graphite block has been used as a sealed material in the early 1950s. At this stage, the current stage. The use of use is st
