Who is related to the wear resistance of graphite products?

Graphite sells various models and specifications of graphite rods, graphite columns, graphite particles, graphite powder, graphite bearings, and graphite tubes, including lubrication, high purity, conductivity, and wear resistance. We can process various shapes of graphite products according to customer requirements.Graphite products have been widely used in industrial machinery due to their wear resistance and lubrication effects. In actual industrial production processes, the oxidation resistance of graphite products has always been a concern of the graphite industry. So what is the relationship between the oxidation resistance of graphite products?It can be seen that the self-lubrication of graphite depends on the presence of air and water. As a lubricating material, the critical value of moisture in the working environment of graphite products is 5g/m3. If it falls below this value, the friction coefficient of graphite products will increase. At room temperature of 300-400 degrees

How does pungeable graphite produce?

Because graphite is a non -polar material, it is difficult to use the small polar organic or inorganic acid intercourse alone, so oxidant is usually used. The chemical oxidation method is generally soaked in the solution of the natural scales in the solution of the oxidant and plug -in agent. Under the action of a strong oxidant, graphite is oxidized, making the macromolecular molecule of the graphite layer into a plane macromolecular with a positive charge. Due to the extrusion effect of the iconic charging between the plane macromolecules with a positive charge, the spacing between the graphite layer increases, and the plug -in agent is inserted between the graphite layer and becomes a graphite. When heating at high temperature, puffed graphite will quickly shrink, and the contraction multiple is as high as tens to hundreds or even thousands of times. The apparent volume of shrinking graphite reaches 250-300 ml/gram or more. The contracted graphite is worm -like, with a size of 0.1

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

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.

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
