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

How to use expansion graphite

1. Protective useExpansion graphite can be used as protective materials, which can be used to protect metal and other damaged objects, such as circuit boards and steel. Because expansion graphite can expand 10 times, it can effectively block the flames and make these objects from burning with flames.2. InsulationExpansion graphite can also be used as insulation materials, because it has good thermal resistance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing the loss of heat, thereby playing the role of heat preservation.3. Filtering useExpansion graphite can also be used as filtering materials, because it has adsorption and can be used to adsorb toxic substances, such as pollutants used in water treatment, which can effectively remove pollutants in water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement useExpansion graphite can also be used as r

How much temperature can the high -temperature -resistant graphite board be held?

How much temperature can the high -temperature -resistant graphite board be held? Graphite and golden steel are a kind of homogenic alien in carbon. There are many types of graphite products manufactured by graphite raw materials, such as graphite rods, graphite molds, high temperature resistance graphite boards, etc. The structure of high -temperature graphite board is an atomic crystal. In the middle of the oxygen atom, it is connected to a covalent price to cause a porous material that stabilizes the positive hexagon. The covalent single -key is a ion key with high keys that can be damaged with high mechanical energy.Many consumers will ask, how much temperature can high temperature resistant graphite board be held?From the perspective of characteristics, high -temperature graphite boards can resist high temperature, and there is no all problem at 1200 degrees. The more high -quality graphite board can bear high temperature above 3000 degrees. High temperature resistance graphite b

The key features of graphite

1. High fever and conduction: In response to the use of raw materials such as graphite with high thermal conductivity, it reduces the time of fusion.2. High temperature resistance: high -temperature resistance has strong impact characteristics, for rapid cold and hot heat, not easy to crack.3. High temperature resistance: high fire resistance, high temperature to 1200 to 1600 ° C.4. Anti -corrosion resistance: strong adhesion to resist melting soup.5. Anti -reflective impact: have a certain anti -reflective impact resistance (when the funds of the melt material are invested, etc.).6. Antioxidant: Graphite is very easy to oxidize at high temperatures in oxidation. Due to the development of oxidation solution, oxidation consumption is less.7. Anti -adhesion: Because graphite is not easy to stick to the soup, the molten soup is soaked and attached with less adhesion.8. There is very little environmental pollution of metal materials: Because there is no bad matter that infiltrate the envi

Excellent Electrical Conductivity of Carbon Graphite Materials and Their Applications

Graphite can conduct electricity because carbon atoms have two 2P electrons with the same spin direction, which are in the valence band (also known as the π band) when in the ground state. When excited, it transitions to the empty conduction band (π * band) above, leaving an equal number of holes in the valence band. Electrons carry negative charges while holes carry positive charges. When subjected to an electric field, electrons and holes move in opposite directions, thus contributing to electrical conduction. Due to the close arrangement of carbon atoms in graphite crystals and the deep degree of electron co-occurrence on the 2P band of each carbon atom, the valence band is wider and can slightly overlap with the upper conduction band. The gap width between them can be reduced to 0.01eV. Therefore, as long as the electrons in the valence band are slightly excited, they can transition to the conduction band, leading to an increase in conductivity. Therefore, the resistance of carbon

What issues should be paid attention to when using graphite crucibles

Graphite crucibles have a wide range of uses in the metallurgical industry, and their main function is to hold various liquid metals. As a metallurgical manufacturer, it is necessary to use graphite crucibles, otherwise there may be some problems in later production and use.Although graphite crucibles are of good quality and not easily damaged, they should also be handled with care. Falling or bumping from high altitude may not have a significant impact on its quality, but if it continues to do so for a long time, it may crack or even break. After this situation occurs, there is no way to remedy it, and we can only replace it with a new one.2. Graphite crucibles are prone to moisture, and the product will become soft after being affected by moisture. When struck by some impactful objects, it will deform. And once water enters the graphite crucible, it will affect the raw materials contained inside, causing dilution of the raw materials, and even causing some chemical reactions to furt

Many new main uses of graphite have already been developed and designed

Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees. This is because carbon must be graphite at a high temperature natural environment of 2000-3300 degrees at a high temperature and natural environment of at least 10 days and
