The sealing end surface of the mechanical seal is composed of rotating dynamic ring installed on the axis and a static ring fixed on the machine seat. It requires good material wear resistance, low friction coefficient, corrosion resistance, high heating rate, strong seismic performance, siliconization, siliconization Graphite can meet these requirements. According to the determination, when the PV value (seal pressure and speed of the speed) reaches 147MPA · m/s, the hard alloy steel ring will generate thermal stress cracks, while the sealing ring of the silicon graphizer is 687MPa · m/ S instead of damage. It can also be used for water sealing such as shielding pumps and high -horsepower diesel engines. Siliconized graphitic can be used as bearing for pumps such as phosphate, phosphoricide and hydrofluoric acid.

Graphite

Graphite is a carbon element crystalline mineral, and its crystalline grid is hexagonal layered structure. The distance between each network layer is 3.40å, and the distance between the carbon atom in the same network layer is 1.42å. It belongs to the hexagonal crystal system, with a complete layer -like lapse. The molecular keys are mainly attractive to the molecular keys, so its natural floatingability is very good. Graphite and diamond, carbon 60, and carbon nanotubes are both the monomer of carbon, and they are similar aliens.Six carbon atoms form a rumor-shaped ring on the same plane, stretching into a layer structure. Here the key length of the C-C key is 142pm, which is exactly the length of the keys of the atomic crystal. Therefore It is an atomic crystal. There is a P orbit left in the carbon atoms of the same plane, which overlap each other. Electronics is more free, which is equivalent to free electronics in metal, so graphite can conduct heat and conductivity, which is ex

What are the factors that affect scales graphite quality?

The quality of scales graphite determines the product quality of the processed scale graphite powder. The scales graphite resources are natural graphite of the light crystal, which is formed by deteriorating quality under the action of long -term geology. The scales graphite crystals are scales -shaped. The scale of the scales of scales graphite and the amount of carbon content is the key factor affecting the quality of scales. The following editors will take you to understand:As the basic processing raw materials of various graphite powder products, the quality of scales graphite is an important condition. According to scales graphite quality, various parameters, etc., scales can be processed into graphite products such as scales graphite, ultra -fine graphite powder, high pure graphite, nanim graphite, colloid graphite and other graphite products. The scale size of the scales graphite determines the lubrication performance of processed. The larger the scale graphite size, the better

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

Classification of Graphene

There are two classification methods for graphene. One is based on the number of layers, which can be divided into four categories: single-layer, double-layer, few layer, and multi-layer products; Another type of product can be divided into three categories according to its form: powder, slurry, and film. Graphene powder and graphene thin film are currently the two main forms of graphene materials. The former is mostly doped in other materials and is widely used in coatings and lithium-ion batteries; Graphene thin films are widely used in the fields of electronics, photons, and optoelectronic devices due to their advantages of transparency, conductivity, and flexibility. Different graphene products have certain differences in raw materials due to different preparation methods. Graphene powder is mainly formed by physical or chemical methods, and the main raw material is natural graphite. Graphene thin films are mainly deposited by chemical vapor deposition, and their raw materials are

Will room temperature superconductivity become the next graphene

On July 22nd, a South Korean research team published a paper on the preprint website arXiv, claiming to have synthesized the world's first room temperature and atmospheric pressure superconductor, named LK-99.Superconductivity refers to superconductivity. Under normal temperature and pressure, almost all conductors have resistance, resulting in thermal energy loss during current conduction. Superconductors are materials that can conduct current with zero loss due to the disappearance of resistance, and have complete diamagnetism (internal magnetic induction strength is zero), with advantages such as stability, low loss, and fast transmission.Previously, superconducting materials needed to enter the superconducting state at lower temperatures. The keyword "room temperature superconductivity" mentioned by the Korean team in this paper refers to the phenomenon of superconductivity achieved under room temperature conditions. According to the standards of condensed matter physics

Method for manufacturing low-density expanded graphite blocks using flexible graphite

In recent years, various types of low-density carbon graphite materials have been actively studied, including carbon (graphite) foam made of mesophase pitch or polymer resin, and carbon nano foam formed when carbon materials are ablated by high repetition rate pulsed laser. Expanded graphite is also a low-density carbon graphite material. Due to the simple preparation process, low production cost, and convenience for large-scale industrial production of expanded graphite, research on expandable graphite has continued to deepen in recent years. The following editor from Jinhui Graphite Company introduced the method of making low-density expanded graphite blocks by soaking flexible graphite in concentrated acid:The worm like shape and weak macroscopic structure of expanded graphite limit its application. If a stable and expandable graphite block can be made, it will be beneficial for expanded graphite to play its role as a functional material for adsorption, insulation, thermal conducti

High power and ultra high power electrodes

The characteristic of high-power and ultra-high-power electrodes is low resistivity, allowing for a current load of 25% -40% higher than that of ordinary electrodes; The allowable current density is greater than twice; Low coefficient of thermal expansion; High flexural strength; Low oxidation loss. The production of high-power and ultra-high-power electrodes uses needle coke as the raw material, and multiple impregnations are used in the production process to increase the graphitization temperature, and corresponding improvements are made to the bonding and impregnating agents.The requirements for ultra-high power graphite electrodes are relatively strict. The volume density of the electrode reaches 1.72g/cm3; The resistivity drops to 5-7 Ω. mX10-6. Due to the fact that the current density allowed by ultra-high power is more than twice that of ordinary electrodes, the thermal stress and impact it bears increase. Therefore, the electrode requires a low coefficient of thermal expansion
