The functions and characteristics of flake graphite

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings. As an anti-corrosion material, it is a rust resistant primer made of carbon black, talc powder, and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect will be better.The manufacturer of flake graphite believes that expandable graphite is a Graphite intercalation compound made from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the volume of expandable graphite rapidly expands (up to 300 times), suffocating the flame and producing expanding substances that can isolate the flame, delay or interrupt its spread, be non combustible, have good flexibility, high surface energy, and good carbonization layer strength. However, the volume and dosage of the expansion body should be appropriate

Factors affecting the gasification reaction of carbon materials

(1) Degree of graphitization: As the degree of graphitization of carbon materials increases, their activity towards gases decreases. The higher the final heat treatment temperature of carbon materials, the higher the temperature at which they begin to oxidize, so graphite products have a higher starting oxidation temperature than carbon products.(2) Structural state: Carbon materials with loose and porous surfaces are prone to react with gases. For example, the surface dense pyrolytic graphite treated at 3200 ℃ begins to oxidize in air at a temperature of 850 ℃, while the porous and loose charcoal on the surface begins to burn at 360 ℃.(3) Catalytic effect of impurities: Carbon materials contain impurities that have a significant impact on their gasification reaction, with varying catalytic effects. For example, iron, cobalt, nickel, copper, manganese, etc. are catalysts for the oxidation of carbon materials, while impurities such as boron, titanium, and tungsten have inhibitory effec

What are the advantages of high pure graphite?

Simplified graphite is an inorganic non -metallic material. High -pure graphite is a common advantage in processing and manufacturing structure casting molds, exercise of high -pure metal, sintering mold, metal coating, and transmitting electron tube. High pure graphite has corrosion resistance, the substrate is uniform and small, delaying the degree of corrosion of the product. In addition, it also has high thermality. High -content fixed carbon ensures good thermal conductivity, shorten the dissolution time, and significantly reduces energy consumption. In particular, its quality stability, the manufacturing technology and quality assurance system of high -voltage molding methods fully ensure quality stability. If graphite molds and graphite processing products of various shapes and uses can be achieved in the metallurgical industry, graphite with accuracy and roughness can be processed. High -pure graphite is specially designed according to the conditions of rapid heating and fast

Unique chemical properties of industrial graphite products

Graphite is an important mineral resource in the 21st century, and China ranks first in the world in terms of graphite ore reserves. With the improvement of graphite product processing technology, it has been widely used in fields such as chemical engineering, smelting, casting, new materials, molds, aerospace, etc. We often see many chemical properties of graphite products in the industry, such as graphite crucibles, graphite heaters, graphite molds, etc(1) High temperature resistance: In smelting, the melting point of graphite products is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles.(2) Good conductivity and thermal conductivity: The conductivity of graphite products is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exce

Introduction to the characteristics of flake graphite

1. As a basic raw material, flake graphite can be processed into ultrafine graphite powder, expanded graphite, nano graphite powder, high-purity graphite powder, etc.2. Flake graphite has good lubricity, high temperature resistance, conductivity, etc. Processed into solid graphite lubricant, widely used in mechanical lubrication.3. The quality of flake graphite depends on its carbon content. By purifying flake graphite, it can be processed into high carbon, medium carbon, and low carbon flake graphite. Each type of graphite has a different carbon content, and the higher the carbon content, the better its industrial use.Flake graphite has strong thermal shock resistance and good corrosion resistance, making it the main carbon material for carbon refractory materials. It has important factors affecting the corrosion resistance and high-temperature working strength of carbon refractory design materials such as magnesia carbon bricks.
