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.

Summary of the characteristics, distribution and purification process of scales graphite

The scale graphite is high -pressure metamorphic. After weathering, it is generally blue -gray, yellow -brown or gray -white. It is mostly produced in tingling rocks, sliced rocks, crystalline litter and silicon hacks. Symbiosis is complicated, mainly consisting of sheet -like crystalline carbon, accompanied by long -stones, Yingshi, Black Cloud Mother, Pymaline Mine, Magnetic Yellow Elephant Mine, Golden Stone and other miscellaneous minerals. The graphite in the ore is a chip -like or blade -shaped, and the black or steel gray is mainly existing between the long stones, the time, the transparency of the pyroxyl, and the permeability of the glitter. It has obvious directional arrangement and consistent with the layer. Scales graphite is mostly natural crystal graphite with a layered structure and looks like fish scales. It belongs to the hexagonal crystal system. The crystalline state is good, the particle size is 0.05 ~ 1.5 microns, the thickness of the thin piece is 0.02 ~ 0.05 mm,

Let's talk about the role of battery dedicated graphene in lithium battery

Because the battery -specific graphene has the above nano -scale effect, good conductivity and excellent mechanical properties, it is widely studied by scientists from all over the world and produced the concept of "graphene lithium battery". Battery?1. anode materialDue to its unique two -dimensional structure, excellent electronic transmission ability, and large surface area of battery -specific graphene, it has a huge potential to replace graphite to become a new generation of lithium -ion battery negative materials. The lithium storage mechanism of graphene is similar to other carbon materials. Both sides of the elene can store lithium ions. At the same time, graphene can also store lithium because of the presence of folds. Therefore, theoretically its capacity may be twice the graphite, which is higher than 744mAh/g.In addition, graphene is mostly micr -nano -size, far less than block graphite, which makes the diffusion path of lithium ions shorter, and the laminar spac

Silicon gifda application field

The sealing end surface of the mechanical seal is composed of rotating dynamic ring installed on the axis and a static ring fixed on the machine seat. It requires good material wear resistance, low friction coefficient, corrosion resistance, high heating rate, strong seismic performance, siliconization, siliconization Graphite can meet these requirements. According to the determination, when the PV value (seal pressure and speed of the speed) reaches 147MPA · m/s, the hard alloy steel ring will generate thermal stress cracks, while the sealing ring of the silicon graphizer is 687MPa · m/ S instead of damage. It can also be used for water sealing such as shielding pumps and high -horsepower diesel engines. Siliconized graphitic can be used as bearing for pumps such as phosphate, phosphoricide and hydrofluoric acid.

How to clean up the active board?

1. Preparation before work: Wear a hood, raindrops, glue gloves, safety helmets, glue gloves must be allowed to simply water, sore water, and allow them to be allowed to work; Add 109 sodium hydroxide solution water solution; turn on the anode rod back cover, use both hands to gently display the graphite anode board from the anode rod, and migrate to the graphite cleaning slot soak for 30 minutes.2.

Graphite mold mold polishing

The mold polishing of graphite mold is accompanied by the common use of plastic products, such as daily chemical tools and drink packaging materials. The appearance must usually specify the surface of the injection molding mold concave mold to be polished. The production of optical lenses, laser laser records and other molds are extremely high in surface roughness, so the provisions of polishing and polishing are also very high. Following and polishing not only enhances the beautiful and generosity of product workpieces, but also improves the corrosion resistance and abrasion resistance of the surface of the raw material, but also enables the mold to have other advantages, so that plastic products are easy to produce and reduce the time of production and manufacturing injection processing cycle.

The main impregnating agents currently used for graphite

(1) Carbon based materials: Most carbon based materials use asphalt, but in order to control the filling rate, tar or asphalt is often mixed with low carbonization rate and low viscosity carbon based materials such as tar and creosote. They are carbonized through heat treatment after impregnation, so the residual material entering the pores is only carbon. The carbon process is currently a standard carbon process aimed at improving density, strength, conductivity, thermal conductivity, corrosion resistance, and wear resistance. It has become the most common treatment method for general carbon materials, especially in the production process of fine structured graphite and UHP electrodes for electric furnace steelmaking. It is an indispensable process. In order to achieve the same goal, there are also cases of impregnating synthetic resin and then roasting and carbonization. The carbonization of synthetic resin generally generates hard carbon, which is characterized by greatly increasin
