Scales graphite has the cause of lubrication and the conditions of use

Scales graphite has many high -quality characteristics, especially good lubrication, so that it is widely used in many fields. Why is the scales graphite good lubricating, and under what conditions are better lubricating performance? Graphite manufacturer Xiaobian will analyze in detail for you:1, scales graphite is lubricated.The scales graphite played its good lubrication when there is water vapor and air. The presence of water and air enables the surface of the scale graphite to absorb water and gas molecules, which increases the distance between the sliding solution and weakens their binding force. On the one hand, the adhesion is also provided by the free keys on the edge of the base surface of the scales. Because water and gas molecules occupy these free keys, the adhesion force is reduced. This is why the scales are lubricated.2, scales graphite lubricating conditions.Scale graphic can only have good lubrication only in the case of water and air. For example, in a thin high alt

Detailed introduction of graphite board characteristics

The characteristics of graphite boards are widely used in the field of metallurgical industry, chemical factories, and photoelectric catalysts. Therefore, it has excellent conductivity, heat resistance, corrosion resistance, and easy production and processing.1. Graphite plate is resistant to corrosive and soft graphite corrosion. Maintain stable organic chemical reliability for general organic chemical organic solvents, petroleum products, lipids, steams, and acres of substances.2. The variety of graphite boards, everyone knows that graphite belongs to the hexagon structure, and the oxygen atom interval in the plane layer is significantly different from the interval between the oxygen atom in the middle and the middle. Therefore, there are significant various conditions at the level of heat transfer coefficient, thermal conductivity and line expansion coefficient.3. The relative density of graphite boards, narrowing and rebounding, and the significant difference between its soft grap

Thermal conductivity of polycrystalline graphite

The so-called carbon materials such as artificial graphite molded products are polycrystalline materials with extremely complex structures, and the basic structure of graphite crystallization has strong anisotropy. Therefore, the macroscopic thermal conductivity of carbon materials, apart from relying on empirical data, is almost unpredictable. The factors that have a significant impact on thermal conductivity include:(1) The differences in the basic properties of the initial raw materials;(2) The manufacturing process - macroscopic anisotropy;(3) Heat treatment temperature - the growth degree of graphite microcrystals;(4) Apparent density, distribution of holes, etc.

Optical and mechanical properties of graphene

Graphene has excellent optical properties, with an absorption rate of about 2.3% over a wide wavelength range, making it almost transparent. Within the thickness range of several layers of graphene, with each increase in thickness, the absorption rate increases by 2.3%. Large area graphene films also have excellent optical properties, and their optical properties change with the thickness of graphene. This is an unusual low energy electronic structure possessed by single-layer graphene. At room temperature, a voltage is applied to a double-gate double-layer graphene field-effect transistor, and the bandgap of graphene can be adjusted between 0 and 0.25 eV. When a magnetic field is applied, the optical response of graphene nanoribbons can be tuned to the terahertz range.When the intensity of the incident light exceeds a certain critical value, graphene's absorption reaches saturation. These characteristics allow graphene to be used as a passive mode-locked laser. This unique absorption

How to distinguish whether Gwangba is clean and tidy?

1. Determine that the graphite boat has no acid and alkali ingredients. (After immersion, you can use pH to detect water or graphite boats that have been used as neutralized to determine the results of the cleaning.)2. Check out the surface layer, graphite guarding point and graphite boat, and whether there are residues of silicon nitride.3. Try the ceramic stick and porcelain sleeve with the dust -free paper -free paper -free paper -free paper.Remarks: The above rules are distinguished under the processing process of all normal washing boats. When the ceramic stick is broken during the whole process of laundering, the insistence is too large, and it needs to be immediately disassembled to prevent everything that endangers the graphite boat. Normal application.

Graphite hydrillinosteric acid method

Hydrofluoric acid is a strong acid, which can react almost with any impurities in the graphite, and graphite has good acid resistance. In particular, it can resist hydrofluoric acid. It determines that graphite can be purified with hydrofluoric acid. The main process of hydrofluoric acid method is mixed with graphite and hydrofluoric acid. The hydrofluoric acid and impurities response generate soluble substances or volatiles for a period of time. After washing and r

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.

Why add graphite powder to glass fiber?

Glass fiber enhanced plastic (FRP) is a composite composite material based on synthetic resin. It has the advantages of light weight, high strength, corrosion resistance, microwave transmission, electrical insulation, and reasonable performance design according to requirements. It has been widely used in aerospace, petrochemicals, transportation, construction, shipbuilding, machinery, environmental protection, textile and other fields. Glass fiber enhanced plastic (FRP) has good electrical insulation property. Under normal circumstances, the amount of graphite powder is 2.5 ~ 5%, which can reach 30 ~ 50%. So why add graphite powder to glass fiber?From an economic and technological perspective, it is best to choose inorganic abrasive materials, so the amount of graphite powder in the abrasion -resistant material of the glass fiber reinforcement is relatively large. In short, glass fiber wear -resistant materials, because its matrix is a polymer material, fills solid lubricants and vari
