Why can graphite blocks be used as sealing rings

In the graphite industry, it is well known that graphite products are widely used in many industries. It is believed that friends who often walk in graphite rings know about graphite sealing rings. So why is graphite used as a sealing material? This is a question worth exploring.Graphite has characteristics that cannot be replaced by other metal materials, such as conductivity, good thermal conductivity, and excellent corrosion resistance. Choosing it as a sealing material also has its own special characteristics. Carbon graphite rings have physical and mechanical properties such as high temperature resistance, self-lubrication, low friction coefficient, wear resistance, and low thermal expansion coefficient. Therefore, graphite sealing rings can be seen in various industrial sectors such as papermaking, textile, and medicine.Moreover, graphite blocks can not only be used as graphite sealing rings, but also as various types of graphite machined parts in other industries.

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

High pure graphite characteristics and application

High pure graphic refers to the carbon content of graphite greater than 99.99 %, and high pure graphite has the advantages of high strength, high density, high purity, good shock resistance, high temperature resistance, anti -oxidation, small resistance coefficient, corrosion resistance, and precision processing. It is an ideal inorganic non -metal material. It is used to process and make electric heating elements, electro -spark processing graphite, sintering molds, electronic tube anode, etc., which are widely used in the metallurgical industry's high -grade refractory materials and coatings Light industry's pencil core, carbon brush of electrical industry, electrode of the battery industry, and catalyst additives of the fertilizer industry, etc., high pure graphite can be produced, and can also produce graphite, graphite sealing materials and composite materials, graphite products, graphite reduction reduction reduction High -tech products such as additives have become an important

Silicon based anode battery capacity

Although graphite has been used as an anode material for power batteries for decades, its large volume, high weight, and physical and chemical limitations make it difficult to meet the high energy density requirements of electric vehicles. Therefore, silicon-based anode materials are gradually replacing graphite and becoming a new direction in the development of power batt

The relationship between graphene and scales graphite

Graphene is stripped from scales graphite materials, composed of two -dimensional crystals composed of carbon atoms, with a thickness of only one layer. Because graphene has excellent performance in optics, electrical, and mechanics. Is graphite related to graphene? Let me analyze the relationship between scales graphite and graphene with everyone:1. The method of extraction of graphene mass production is not obtained from scales graphite, but from carbon -containing gas such as methane and acetylene. Although the word graphite is used in the name, the production of graphene is not mainly from scales graphite. On the contrary, it is obtained from carbon -containing gas such as methane and acetylene. Even the current research method is extracted from the planting plant tree. Now there is a method for extracting graphene from the tea tree.2, scales graphite contains millions of graphene. Graphene is actually in nature. If the relationship between graphene and scales graphite is mentione

Graphite chloride roasting method

The chloride roasting method is to mix graphite with a certain reducing agent to bake at high temperature in specific equipment and atmosphere. The price in the material is transformed into a metal chloride with gas or condensed phase. Purified process.

Graphite melting point

Graphite is a kind of homogenous alien in element carbon. Each carbon atom is connected to the other three carbon atoms (multiple hexagonal sixtures with honeycomb -shaped hexagonal) with covalent bonds to form covalent molecules. [1] Because each carbon atom will release an electron, those electrons can move freely, so graphite is a conductive body. Graphite is one of the softest minerals, and its purpose includes a pencil core and lubricant. Carbon is a non -metal element that is located in the second cycle IVA family located in the element cycle table. Latin is Carbonium, which means "coal, charcoal".The melting point of diamond is 3823K, and the melting point of graphite is 3773K. Graphite melting points are lower than diamonds. The melting point of graphite and diamond cannot be considered simply from the aspects of the key energy. If the number of broken keys during melting is ignored, the data obtained is not desirable

Why add graphite powder to glass fiber?

Glass fiber enhanced plastic (FRP) is a composite composite material based on synthetic resin. It has the advantages of light weight, high strength, corrosion resistance, microwave transmission, electrical insulation, and reasonable performance design according to requirements. It has been widely used in aerospace, petrochemicals, transportation, construction, shipbuilding, machinery, environmental protection, textile and other fields. Glass fiber enhanced plastic (FRP) has good electrical insulation property. Under normal circumstances, the amount of graphite powder is 2.5 ~ 5%, which can reach 30 ~ 50%. So why add graphite powder to glass fiber?From an economic and technological perspective, it is best to choose inorganic abrasive materials, so the amount of graphite powder in the abrasion -resistant material of the glass fiber reinforcement is relatively large. In short, glass fiber wear -resistant materials, because its matrix is a polymer material, fills solid lubricants and vari

What is the use of spherical graphite?

Ballog graphite is widely used in the market and is widely used in industry, agriculture, and industrial and mining. The wide application field is an important additive in industrial production. So where is spherical graphite applied.1. Ballog graphite as refractory material: Graphite structure and its related product companies have a high temperature resistance and high -strength properties. In the metallurgical machinery industry, it can be mainly used to make graphite crickets in the manufacturing process.2. Ballog graphite as conductive materials: used to manufacture electrodes, carbon pipes, mercury rectifiers, telephone parts, TV visual pipes, etc.3. Ballog graphite is used as abrasive lubrication material: Graphite is often lubricant in the mechanical industry.
