Application of flake graphite in the coating industry

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings.As a anti-corrosion material, it is made with carbon black, talc powder, and oil as an anti rust primer, which has good resistance to chemical and solvent corrosion. If chemical pigments such as zinc yellow are added to the formula, its anti rust effect is better.The expandable graphite used as a fireproof filler is a graphite interlayer compound obtained from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the expandable graphite rapidly expands in volume (up to 300 times), suffocating the flame and generating an expanding substance to isolate the flame, delay or interrupt the flame spread. It is also non combustible, has good softness, and has high surface energy, The carbonization layer has good strength. However, the volume and dosage of the expansion body should be selected appropriately. Exper

In-depth analysis of the physical and chemical properties of graphite and its industrial value

Graphite, an ancient and magical substance, possesses a series of remarkable physical and chemical properties, which make it a pivotal position in the industrial field.First, graphite has excellent electrical and thermal conductivity. This characteristic makes graphite occupy an important position in the electronics industry, and is widely used in the manufacture of electrodes, conductive coatings, etc. At the same time, the high thermal conductivity of graphite also makes it have broad application prospects in the field of heat dissipation materials.Secondly, the chemical stability of graphite is extremely high. It can resist the erosion of most acids, bases and organic solvents, which makes graphite in chemical industry, metallurgy and other fields have a wide range of applications. For example, graphite can be used as a material for corrosion-resistant pipes, vessels, and reactors.In addition, graphite also has good lubricity and plasticity.

The Application of Graphite Processed Parts in Industry

Graphite machined parts are widely used in industry due to the excellent characteristics of artificial graphite materials that cannot be replaced by other metal materials.Graphite machined parts have good conductivity, and with the development of the industry, the size of graphite sheets also changes. In addition, graphite machined parts can also be used as lubricating rings in the electromechanical manufacturing industry as conductive materials.Due to the integration of high-temperature and corrosion resistance of graphite materials into graphite machined parts, many metallurgical furnace linings are made of graphite materials. However, graphite machined parts used as refractory materials must undergo good oxidation resistance treatment when used in oxidizing degassing.Graphite machined parts can be used as corrosion-resistant structural materials. All graphite machined parts need to be impregnated with organic resin to achieve optimal corrosion resistance. Most of them are used as b

Types of products impregnated with graphite

(1) Small specification graphite electrodes and joint blanks, various specifications of graphite anodes, fine structure, high-strength, and high-density graphite. These products need to have high density and strength, as well as low electrical resistivity, so the baked semi-finished products are first impregnated with coal tar pitch and then graphitized.(2) Diaphragm type salt solution electrolysis cell graphite anode. Graphite anodes impregnated with coal tar pitch can generally last for 8-9 months, while graphite anodes that are not impregnated can only last for 5-6 months. The main reason for affecting the lifespan of graphite anodes is that the electrolyte penetrates into the pores of the anode, while hydroxide ions, sulfate ions, and hypochlorite ions in the electrolyte discharge on the anode, generating primary oxygen. This initial oxidation reaction of oxygen on the anode causes chemical corrosion, which accounts for about half of the loss. Additionally, chemical corrosion weak

What is the role of scales when galgling?

The application of scales graphite is widely used in industries. Mulchogenic sand is one of the applications of them. Cover sand refers to the sand or core sand with a solid resin film on the surface of the sand grain. In the middle, scales need to be used. Today, I will explain what the scales have the functions when gog graphic is covered with membrane sand:The scaled graphite is used as a lubricant in the lubricant in the sandy sand. The littering of the luster sand can play a lubrication and high temperature resistant role in the sandwich sand. For the requirements of scales with scales in gifsta, it is required to be lubricated as a lubricant and high melting point, and the littering of the lubrication is a natural scale graphite with good lubrication. Carbon content. The melting point of the scale graphite itself is very high. After the production process processing, the high temperature resistance of scales graphite with scales with scales will be higher, and the lubrication ef

Let's talk about the basic characteristics of graphite

I. Special seismic resistance: Graphite's expansion gear is different, so the macro expansion coefficient is not large. In the case of sudden changes in temperature, graphite volume has not changed much; coupled with its good thermal conductivity, graphite resistance is excellent.Second, lubrication: The graphite layer is Van Der Waal Forces, which combines weak combination to make it lubricating. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, the better the lubricity.Third, good chemical stability and resistance to erosion: Graphite has good chemical stability at room temperature, not subject to any strong acid, strong alkali and organic solvents; the carbon atom in the graphite layer is firm Combining, the surface of graphite phosphorus can be very low, not moisturizing by melting furnaces, and strong resistance to erosion. However, graphite is prone to oxidation in the air, and anti -oxidation mea
