What is the application of natural flake graphite?
Wholesale gas prices in the Netherlands and the UK have risen 20 percent recently amid concerns about Russian supplies.
The EU plans to cut its dependence on Russian gas by two-thirds this year and stop importing Russian fossil fuels by 2027. Russia exported about 155 billion cubic meters of gas to the EU in 2021.
The US recently said it would try to supply 15bn cubic meters of LNG to the EU this year. U.S. LNG plants are running at full capacity, and analysts say much of the extra gas the U.S. sends to Europe comes from what should have been exported elsewhere.
The German government called Russia "an unreliable energy supplier". Even though the German government claimed that they have been preparing for the situation for a long time that Russia may stop sending gas one day, experts say it is hard for the EU to replace all of Russia's gas exports any time soon.
The supply and prices of many natural flake graphite will continue to be influenced by international situations.
Natural flake graphite are widely used in advanced refractories and coatings in the metallurgical industry. Such as magnesia carbon bricks, crucibles, etc. Pyrotechnic material stabilizer in military industry, desulfurization accelerator in smelting industry, pencil lead in light industry, carbon brush in electrical industry, electrode in battery industry, catalyst in fertilizer industry, etc. After in-depth processing of flake graphite, graphite milk can be produced, which is used in lubricants, mold release agents, wire drawing agents, conductive coatings, etc. It can also produce expanded graphite, which is used as raw material for flexible graphite products, such as flexible graphite seals and flexible graphite composite products.
As a functional filler of coatings, flake graphite is mainly used in anti-corrosion coatings, fire-retardant coatings and conductive coatings.
As an anti-corrosion material, it is an anti-rust primer made of carbon black, talc and oil, which has good chemical and solvent corrosion resistance; if chemical pigments such as zinc yellow are added to the formula, the anti-rust effect is better.
Expandable graphite is used as a fireproof filler, which is a graphite interlayer compound obtained by chemical or electrochemical treatment with natural graphite flakes as raw materials. Under the condition of heat, the volume of expandable graphite expands rapidly (up to 300 times), which suffocates the flame, and at the same time generates expandable materials, which can isolate the flame, delay or interrupt the spread of the flame, and is non-flammable, with good flexibility and high surface energy. , the carbonized layer has good strength. However, the volume and amount of the expansion body should be selected appropriately. The test shows that 150um particles, 30% expansion ratio, and 5% dosage are the most suitable.
Graphite flakes can be directly used as carbon-based conductive fillers or made into composite conductive fillers for conductive coatings. However, due to the large amount of graphite flakes added, the performance of the coating will become brittle and its application will be limited. Therefore, measures should be taken to further improve the conductivity of graphite and effectively reduce the amount of graphite flakes added. The domestic Tianhua Chemical Machinery Research Institute has developed a high-temperature corrosion-resistant resin as the base material and large flake solid graphite flakes with strong electrostatic conductivity as the main aggregate, which has high body strength and good wear resistance.
The chopped fiber material with good resistance to deformation and cracking is a solvent-free thick-film conductive coating with functional fillers. The coating has the characteristics of anti-corrosion medium penetration, low curing residual stress, good resistance to matrix deformation and cracking, stable construction performance, and long-term static electricity conduction. It can be used for electrostatic conductive coating on the inner wall of crude oil storage tanks. According to data reports, electroless plating technology is used to coat graphite powder with metals, such as copper, nickel, silver, etc. to prepare composite conductive fillers, which are used in conductive coatings in an amount of 30%, which not only has good electrical conductivity, but also has further corrosion resistance. improve.
