How to maintain graphite processing into graphite stick products?

1. During the use of graphite stick products, the graphite stick products are turned once a week to extend the life of graphite stick products;2. Using an appropriate amount of combustion agent, additives will reduce the life of graphite sticks;3. Keep a proper distance between the graphite stick and the wall of the furnace, and the graphite stick products should be placed in the furnace positive;4. When removing the inside of the graphite rod product, the inside of the wall of the graphite and sticking should be tapped to prevent damage to damaging graphite rod products;5. Graphite products are strictly preventing humidity. They must be placed on a dry place or wooden stand during storage.

The production method of graphite bearings

Graphite bearings, due to their self-lubricating, high and low temperature resistance, corrosion resistance, and other characteristics, can meet the sealing requirements for strong corrosion, flammable, explosive, and radioactive media. Effectively solving the problems of "running, emitting, dripping, and leaking" in chemical equipment, it has a good effect on improving labor conditions, product quality, and productivity.Graphite bearings can be divided into rolling bearings and sliding bearings, and there are also different materials such as metal, non-metal, and composite materials. Graphite bearings are commonly used in sliding bearings, which are further divided into radial bearings and thrust bearings. The article mainly analyzes carbon graphite bearings, bronze graphite oil bearings, and embedded graphite bearings.The manufacturing method of graphite bearings is characterized in that it is achieved by the following technical solutions:1) . Model making: polystyrene foam plastic

Graphite powder from graphite manufacturers

Graphite powder produced by graphite manufacturers is a widely used industrial material, which is obtained by crushing, grinding, and screening high-purity graphite through rolling. The key to the type of graphite powder is the particle size, which varies from 50 to 30000 mesh. The more mesh the screen, the finer the particle size, and the higher the price. Previously, our country's technological strength could not be achieved, and high-end graphite powder relied on imports. However, at present, Chinese manufacturing enterprises have introduced cutting-edge overseas powder mills, which can produce fine graphite powder with global particle size and have been applied in many industries both domestically and internationally.Graphite manufacturers offer various types of graphite powder, including lubricating graphite powder, conductive graphite powder, nanotechnology graphite powder, high-purity graphite powder, and graphite powder screens with mesh sizes of 150, 425, 1000, 3000, 5000, 65

What is the purpose of spherical graphite?

Spherical graphite has a wide range of market applications, widely used in industry, agriculture, and mining. It has a wide range of applications and is an important additive material in industrial production. So where are spherical graphite used.1. Spherical graphite as refractory material: The graphite structure and its related products have the properties of high temperature resistance and high strength, and can be mainly used in the metallurgical machinery industry for graphite crucibles and other manufacturing processes.2. Spherical graphite as a conductive material: used for manufacturing electrodes, carbon tubes, positive electrodes for mercury rectifiers, telephone parts, television tubes, etc.3. Spherical graphite as a wear-resistant lubricating material: graphite is commonly used as a lubricant in the mechanical industry. Lubricants typically cannot be used at high speeds, temperatures, and pressures, and wear-resistant materials can be graphite at high sliding speeds.4. The

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

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

The functions and characteristics of flake graphite

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings. As an anti-corrosion material, it is a rust resistant primer made of carbon black, talc powder, and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect will be better.The manufacturer of flake graphite believes that expandable graphite is a Graphite intercalation compound made from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the volume of expandable graphite rapidly expands (up to 300 times), suffocating the flame and producing expanding substances that can isolate the flame, delay or interrupt its spread, be non combustible, have good flexibility, high surface energy, and good carbonization layer strength. However, the volume and dosage of the expansion body should be appropriate

The formation of KISH graphite

Whether it plays an important role in the growth of KISH graphite or the growth of KISH graphite according to layer -like crystal, oxygen is an important role. Practice has proved that when the co -crystal iron fluid is exposed to the air, the KISH graphite is easy to form; turning the iron solution and the update surface can exacerbate the precipitation of KISH graphite. The action of oxygen is to form SiO2 as the base of KISH graphite nucleus. The temperature of the iron liquid temperature at below 1400 ° C is severe than high temperature because of SiO2, which is unstable above 1400 ° C. The precision phenomenon of KISH graphite cannot be seen in the low Si or Si iron liquid, which shows that the existence of SIO2 has an impact on the formation of KISH graphite that cannot be ignored.The cooling speed is the basic process conditions formed by the formation of KISH graphite when the existence of oxygen (such as hydrogen protection). KISH graphite can only be formed at a lower coolin

Factors affecting the impregnation effect

The factors that affect the impregnation effect include: firstly, the impregnation process conditions (such as temperature and pressure), and secondly, the physicochemical properties of the impregnation.Influence of process conditions(1) Temperature (product preheating temperature, impregnation tank temperature, impregnation agent temperature), depending on the impregnation process: 1. The product is preheated too high and is prone to oxidation; The temperature is too low, and when it comes out of the preheating box, it quickly cools down and enters the impregnation tank. When the impregnating agent encounters cold products, its viscosity increases and its fluidity deteriorates, resulting in poor impregnation effect. 2. If the tank temperature is too high, asphalt is prone to oxidation condensation reaction, viscosity will also increase, and flowability will deteriorate; The tank temperature is too low, the fluidity of asphalt is also poor, and the impregnation effect is not ideal.(2)
