Overview of natural flake graphite C powder：
Flake graphite is natural crystalline graphite,which is shaped like fish phosphorus, belongs to the hexagonal crystal system,and has a layered structure.It has good high temperature resistance,electrical conductivity,thermal conductivity,lubrication,plasticity and acid and alkali resistance.High-purity high-carbon natural flake graphite C powder CAS 7782-42-5 is prepared by laser ablation,and is widely used in conductive coatings,glass manufacturing,lubricant formation,metal alloys,nuclear reactors,powder metallurgy and structural materials.
Application of natural flake graphite C powder：
What is the scope of application of natural flake graphite C powder?
Natural graphite is mainly used in refractory materials,steelmaking, expanded graphite,brake pads,casting surfaces and lubricants.Natural graphite has been found to be used as a marking material("lead")in ordinary pencils,zinc-carbon batteries,motor brushes,and various applications.Aluminum/graphite composites for engine bearings,pistons and cylinder liners;carbon adsorbents for gas chromatography;copper/graphite and silver/graphite nanocomposites for brushes and contact strips;inorganic fillers(graphite/polymer nanocomposites );graphite/polymer nanocomposite,the carrier material of precision metal powder catalyst,can enhance conductivity;metal matrix composite can reduce friction.
Flake graphite is widely used in advanced refractories and coatings in the metallurgical industry.Such as magnesia carbon bricks,crucibles,etc. Stabilizers for pyrotechnic materials in military industry,desulfurization accelerators for smelting industry,pencil leads for light industry, carbon brushes for electrical industry,electrodes for battery industry,catalysts for fertilizer industry,etc. After intensive processing of flake graphite,graphite emulsion can be produced,which can be 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 for anti-corrosion coatings,fireproof coatings and conductive coatings.As an anti-corrosion material,it is made of carbon black,talcum powder and oil,etc.,which has good corrosion resistance to chemicals and solvents;if chemical pigments such as zinc yellow are added to the formulation,the anti-rust effect is better .
Expandable graphite is used as fireproof filler,which is a kind of graphite interlaminar compound obtained by chemical or electrochemical treatment with natural graphite flakes as raw material.Expandable graphite expands rapidly(up to 300 times)in volume under heating,suffocating the flame,and at the same time,it generates expansions to isolate the flame, delay or interrupt the flame spread,and it is non-combustible, lexible,and has high surface energy.The strength of the carbonized layer is good. However,the volume and dosage of the expansion body should be selected appropriately.Tests show that 150um particles,30% expansion ratio,and 5% dosage are the most suitable.
Flake graphite can be directly used as a carbon-based conductive filler or can be made into a composite conductive filler 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 have been 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,with high body strength and good wear resistance.
The short-cut fiber material with good resistance to deformation and cracking is a solvent-free thick film conductive coating with a functional filler.The coating has the characteristics of anti-corrosive 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 tank. According to reports,the 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 conductivity,but also has further corrosion resistance.improve.
Natural flake graphite price:
Affected by the recovery of the world economy on the graphite industry,the demand for graphite in the world has increased steadily in recent years. According to statistics from the United States Geological Survey(USGS),graphite flakes are mainly distributed in China,Australia, Brazil,Canada,Germany and Madagascar.China has the largest output of 750,000 tons,accounting for 68% of the world's graphite output.The main exporters of natural graphite are China, Mexico,Canada, Brazil, and Madagascar.These countries export 97%of the world's graphite, accounting for90%of graphite exports.Earthy graphite is mainly exported from Mexico, bulk graphite is exported from Sri Lanka,and China,Canada, and Madagascar export crystalline flake graphite.
