Adsorption agent of industrial oil.

Expansion graphite is easily adsorbed, organic molecules and hydrophobic substances, which are used for water environmental protection. It has an irreplaceable effect of other substances. When it is used in a particle -shaped form to remove oil, according to the size of the oil area and the type of oil on the water surface, its dosage is 1 to LO% /RN, and the adsorption time can be ranging from 15rain to a few H.

Graphite mold for antioxidant treatment

1. Heating and conductive: The heterogeneity of graphite is 300 times that of the normal non -non -non -metal mine. Conductivity surpasses non -metal materials such as steel, iron, lead. The conductivity coefficient increased with a decrease in measure, and even at a high degree, graphite became armatologist.2. Chemical stability: Graphite is excellent chemical stability at normal temperature, and the erosion of acid, alkali resistance and inorganic solvents.3. Smooth: The smooth function of graphite originated from the size of the graphite scales. The larger the scales, the smaller the conflict coefficient, and the better the smooth function.4. Plasticity: The graphite is tough and can be crushed into a thin crack. 5. Taxation shock: Graphite can be banned violently at the time of normal temperature and can be banned violently without destruction. When the measurement gradually changes, the volume of the graphite is not large and no cracks will occur.6. Low temperature resistance: T

Graphite application

1. The oxidation and reduction method is used to synthesize graphene to prepare graphene modified electrodes to detect the four bases of DNA. Electrochemical research has found that graphene modifiers can achieve the four bases of DNA at the same time. The graphene and carbon nanotubes and β-cyclic paste are compounded. The carbon nanotuba effectively reduces the gathering of graphene. For high -sensitivity testing for berin nucleoside, the modified electrode can be promoted and applied to the determination of other biomolecules.2. The functionalization of biomolecular single-chain DNA (SSDNA) and graphene, and the prepared SSDNA-graphene composite materials can Stability. SSDNA-graphene composite material is larger than the surface area and has good biocompatibility. It is an excellent oxidation and restorease fixed material. Fix the SSDNA-graphene composite material to prepare glucose sensors for glucose oxidase. Glucose oxidase is realized directly electrochemical and maintains bio

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

Introduction to Graphite Carbon Products

1. Used as refractory material: Graphite and its products have properties of high temperature resistance and strength, and are mainly used in the metallurgical industry to manufacture graphite crucibles. In steelmaking, graphite is commonly used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. As a conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes for mercury positive current transformers, graphite gaskets, telephone parts, coatings for television tubes, etc.3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the mechanical industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can work without lubricating oil at high sliding speeds at temperatures of 200-2000 ℃. Many devices that transport corrosive media are widely made of graphite m

Skin graphite mineral procurement agent

Scales graphite is a crystalline crystal carbon. It has high electrical and thermal conductivity, high temperature resistance, stable chemical properties, low hardness and slippery. It is easy to adhere to the solid surface and can draw clear dark stripes on the paper. These excellent properties of the mineral selection process and minerals have made it widely used in industry. The following is the scales graphite minerals introduced by scales graphite manufacturers:Graphite ingredients, mining agents are mainly flotal, sometimes shaking sorting. This thin piece uses a static electricity selection method, but because the electrical selection needs to be fully dry and accurate, it is difficult to manage high -voltage power management in a humid environment, difficulty in processing fine particles, and cannot be promoted.In non -metal minerals, graphite is a relatively easy to float mineral. Therefore, scales graphite can only float well with foaming agents (such as pine oil oil, methax

What are the key applications of graphite model

What are the critical use of graphite molds in recent years? Graphite has gradually become preferred materials for mold production with its excellent physics and organic chemical properties. Graphite molds are generally used in various industries. Below, let's take a look at the key use of graphite molds.1. Rare metal forging and semi -continuous forging for graphite moldsArtificial synthetic graphite is the best material as a continuous or semi -continuous forging mold for rare metals. Manufacturing practice has proved that because of the selection of graphite molds, its heat transfer performance is excellent (heat transfer performance. The condensation rate of metal materials or aluminum alloys is decided), and the self -lubricating bearing characteristics of the mold are good. Improve, and because of the accurate specifications of casting, clean surface, and well -proportioned crystalline mechanism, the production and processing of the next process process can be carried out.

Graphite mold accessories are getting higher and higher

Graphite mold accessories may become higher and higher for high precision regulations. Ten years ago, the precision of precision machinery manufacturing was generally 5 microns. Now it has achieved 2 ~ 3 μm, and the precision of 1 micron precision will be released. This specifies ultra -deep processing. Mobei Industry Chain will be replaced with increasingly importing. This is also caused by the increasingly imported alternative and high productivity regulations of Moden. The multi -purpose compound shell of the machinery processing industry will further develop. In addition to the forming parts of the stamping mold, the new multi -purpose composite mold shellfish also shoulders the daily tasks such as stacking, attacking, riveting and card tightness, and the characteristics of stainless steel plates are also higher and higher.Graphite molds are complete and diverse. Because of its excellent comprehensive ability, you can see it everywhere.

Scales graphite price tends to be stable

At the beginning of the month, the price of scales in Shandong was stable as a whole. At present, the mainstream price of -195 mainstream prices are 6300-6500 yuan/ton, which is the same as last month. Entering winter, most of the scale graphite companies in the Northeast are suspended for production holidays. Although a few companies are in production, the output is reduced and the inventory reserves are not much.The scale of the scale graphite market has been poor some time ago and the demand for material resistance has declined, which led to a decline in the price of scales, and corporate quotations were chaotic. As the Spring Festival holiday approaches, due to the suspension of production in the Northeast region, graphite supply has declined, and downstream enterprises have been basically completed. The supply demand for scales graphite market is plain, and the offer is relatively stable.In 2021, the export situation of scales was relatively sluggish. According to customs statist
