Expansion graphite, a new multifunctional insulation material

Expansion graphite is a kind of graphite that can expand and shrink in high temperature environments. This material has very special physical and chemical properties. Graphite is a kind of carbon, and its structure is connected by hexagonal carbon atoms. Generally, graphite can be completely melted, but at high temperature, due to the enhancement of the interaction between carbon atoms, graphite can form more stable stability The structure of the expansion is achieved.1. The development of expansion graphiteThe development of expansion graphite dates back to the 1960s. At that time, scientists discovered that graphite can be deformed regularly within a certain temperature range, and the translucent graphite can remain stable. Subsequently, scientists also found that under certain conditions, graphite at high temperature can be used to create a variety of structures, and these structures can be used to support greater weight and develop the technology of expanding graphite.Second, the

The development and application of battery materials

Computers, cars, airplanes, and space capsules all need battery as power, and the core of the battery is battery material. According to its chemical composition and structure, it can be roughly divided into the following categories:The main ingredients are alloys of lead and lead, copper, zinc, tin, etc. Lead -acid batteries are a mature, stable energy storage equipment, which are widely used in automotive, UPS and other fields.Cobalt, nickel, manganese, iron and other elements. Lithium -ion batteries have become one of the popular batteries due to their high energy density, long life, and no pollution. Widely used in mobile power, electric vehicles, drones, smart homes and other fields.Nickel, cobalt and other elements. Because of its high capacity, long life and other characteristics, nickel -metal hydride batteries have become one of the main batteries in satellite, ships, electric tools and other fields.The main ingredients are oxygen in aluminum and air.

Flake graphite processing

Flake graphite is obtained by mining and processing from graphite mines. The types of ore mined are different, and when processing flake graphite, it is also necessary to process it correctly based on the characteristics of the graphite ore. So how should we proceed with the operation? Let's have a simple understanding of flake graphite below.1. Mineral processing method for flake graphite cryptocrystalline graphite.Cryptocrystalline graphite crystals are very small, hence also known as microcrystalline graphite. Graphite particles are usually embedded in clay and difficult to separate. Due to the high grade of the raw ore (usually containing carbon), many graphite mines directly crush and process the extracted ore, selling graphite powder products.2. Mineral processing method for crystalline graphite in flake graphite.The natural floatability of crystalline graphite is good, and it is basically used in China. Due to the particle size of graphite sheets being one of its most important

Two ways of formation of scales graphite

The application of scales graphite in the industry is very widely used, and it plays a pivotal role. my country is one of the countries with rich scales in the world in the world. So how does the scales graphite ore formed? Two causes of biology, the following editors will explain the two formation methods of scales graphite for everyone:1. Bio -graphite biological causesBiological causes refer to the scales graphite directly from organic matter, commonly in marble, sliced rocks, or hemp rocks. Coal seams or carbon -containing sedimentary rocks can form scales graphite. It is the metamorphic mineral of graphite, which is made of organic or charcoal.Second, the non -biological cause of graphiteNon -biological causes refer to the reducing carbon out of CO and CO2. In the contact zone between magma rocks and limestone, scales are often produced. This is due to the decomposition of carbon dioxide by limestone and degenerate. The formation of mineral beds must concentrate and have suitable

The price of graphite powder of graphite manufacturers is more cost -effective

Graphite manufacturers' colloidal graphite powder has a good lubrication performance, high cost -effectiveness, and catalytic reaction characteristics. It is very durable at the same time. It can be made into various products. Collagen graphite powder is commonly used as lead -acid batteries, conductive plates, high -capacity lithium battery positive and negative polar conductors, and thermal lubricating solution raw materials.The corporates of colloidal galgin powder of graphite manufacturers are often used below:1. Good moisturizing characteristics, commonly used as agricultural and animal husbandry organic fertilizer metal catalyst production process in the production process of the production process.2. It can withstand a high temperature of thousands of degrees, and is often used to resist thermal lubricating solution raw materials and anti -corrosion lubricating solution raw materials.3. Powder -unsurgical decrease agent and metal alloy raw materials, lubricating solution in cab

Several use of graphite stick products

1. As a conductive raw material applicationWhen using an arc furnace or ore electric furnace smelting plant, a variety of carbon steel, non -ferrous metals or production of carbonized (calcium carbide), and yellow phosphorus, strong current volume according to the electrode of the carbon plant (or continuous self -baking electrons-- - That is, the electrode paste) or the high -purity graphic electrode to introduce the smelting area of the electric furnace, which causes the electromagnetic loneliness, so that the electromagnetic can be converted into energy, and the temperature rises to up to 2,000 degrees Celsius, which will exceed the smelting plant or the regulations reflected.2. Application of refractory insulation materialsBecause charcoal and graphite products can resist heat and have good high temperature pressure resistance and corrosion resistance, many metallurgical industry furnaces can be built with charcoal to build walls, such as the bottom of the furnace, the furnace tan

The difference between flake graphite and expanded graphite

Flake graphite is a type of natural graphite that, after being extracted and purified, generally appears in the form of fish scales, hence it is called flake graphite. Expandable graphite refers to flake graphite that, after acid washing and intercalation treatment, expands by about 300 times compared to the previous graphite. It can be used as raw materials for coils and flexible graphite. Below, let me introduce in detail the differences between flake graphite and expandable graphite:1. The use of flake graphite is more extensive than that of expandable graphiteIn industrial production, flake graphite not only has the function of expandable graphite, but also has much better conductivity, thermal conductivity, smoothness, and so on than expandable graphite. So its practical use in industry is becoming increasingly widespread.2. The production processes of flake graphite and expandable graphite are differentFlake graphite is mainly made by mechanical damage and grinding. Expandable g

Is it true that diamonds "fly" out of graphite powder

Do you know what a diamond is? Its chemical composition is carbon (C), and natural diamonds can only be called "diamonds" after being polished by diamonds. Natural diamonds are very rare, with only 2 diamonds weighing over 1000 carats (1 gram=5 carats) in the world and only a few diamonds weighing over 400 carats. The largest diamond discovered in China to date weighs 158.786 carats, which is known as the "Changlin Diamond". Rare things are precious, and precisely because natural diamonds that can be used as "diamonds" are rare, people want to replace them with "artificial" diamond, which naturally reminds them of the "twin" brother of diamonds - graphite.The chemical composition of diamond and graphite is carbon (C), which scientists refer to as "homomorphic variants" or "allotropes". From this term, it can be inferred that they share the same "quality", but their "form" or "nature" are different and vastly different. Diamond is currently the hardest substance, while graphite is one
