Preparation process and application of ultrafine graphite powder

Ultrafine graphite powder is one type of graphite powder. The raw material of ultrafine graphite powder is natural flake graphite, which is crushed using an airflow grinder or ultrafine micro grinder. Ultrafine graphite powder with a particle size of 6-10 μ m. It's ultrafine graphite powder.The preparation process of ultrafine graphite powder is as follows: natural flake graphite and raw material coke enter the crushing chamber through a feeding injector with compressed air, and are distributed at the nozzles outside the crushing chamber to inject ultra-high speed airflow into the crushing chamber, causing the coke powder to collide and rub with each other at high speed to form micro powder. The airflow with micro powder is discharged into the grading chamber through the outlet pipe, separating the coarser particles and being crushed again through the return pipe, The remaining micro powder is collected in stages using a cyclone separator and a bag collector. Ultrafine graphite powder

What is the application scope of industrial graphite powder

The application of scales graphite in rust protection

Scale graphite should be no stranger. The scales graphite is very wide, such as lubrication, conductivity, etc. So what are the applications of scales graphite in rust?Apply the scales graphite on a solid and then put it in the water. We will find that the solids that have been applied by the scales will not be wet by the water. Even if it is soaked in water, it will not be wet. The layer protective film is separated from the water from water, which is enough to indicate that the scale graphite is not soluble in water. Using the characteristics of graphite can be used as a good rust -proof paint, coated with metal chimneys, roofs, bridges, pipes, and can effectively protect the metal surface from corrosion of atmosphere and seawater, and has good anticorrosive rust and anti -anti -rust performance.This situation is often encountered in life. The connection bolt or steam pipe flange of the cleaning equipment is very easy to rust, which brings great trouble to maintenance and disassembl

What are the steps of carbon felt purification?

Carbon felt is a major element in many alloy products, so carbon felt purification plays an important role in alloy production. Meanwhile, in the smelting process of metal silicon, silica, ore, etc. are usually used. Silicon slag will also be produced during the smelting process, and silicon slag also contains a certain amount of industrial carbon felt, so we can use carbon felt slag to further purify carbon felt.The first step is to separate the obvious light-colored slag and dark-colored slag from the silicon slag with a manual hammer, and then use the separation principle to further separate the silicon content in the silicon slag.Impurities in silicon slag exist in two forms: reduced and unreduced. In industrial silicon, a flocculant composed of Na2O5~50%, SiO250~95% or Na2O5~50%, SiO250~95%, MgO and CaO is added to industrial silicon. With 35% flux, the melting point of the slag can be reduced from the original 1450 to about 1480 and then down to about 1000. It can also reduce th

Factors affecting the impregnation effect

The factors that affect the impregnation effect include: firstly, the impregnation process conditions (such as temperature and pressure), and secondly, the physicochemical properties of the impregnation.Influence of process conditions(1) Temperature (product preheating temperature, impregnation tank temperature, impregnation agent temperature), depending on the impregnation process: 1. The product is preheated too high and is prone to oxidation; The temperature is too low, and when it comes out of the preheating box, it quickly cools down and enters the impregnation tank. When the impregnating agent encounters cold products, its viscosity increases and its fluidity deteriorates, resulting in poor impregnation effect. 2. If the tank temperature is too high, asphalt is prone to oxidation condensation reaction, viscosity will also increase, and flowability will deteriorate; The tank temperature is too low, the fluidity of asphalt is also poor, and the impregnation effect is not ideal.(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. Therefore, polishing and polishing is an important process in the process of injection molding.The mold polishing has two meters; one is to increase the smoothness of the mold, so that the sur
