The components of high -quality wiper and motor should be added with graphite powder. The wiper with graphite powder has excellent performance such as high temperature resistance, lubrication, and corrosion resistance.The following is a special function of the wiper with graphite powder:The car wiper is installed on the front window of the car, often exposed to high temperature and low temperature, and exposed to wind and sunlight. When the wiper works, it is basically in rainy days. When the wiper works, it should rub the glass of the car's front window, take the rainwater, etc., and clean the window. The wiper will be damaged if used for a long time. When producing a good quality scraper, graphite powder is usually added. The parts in the wiper motor are also made of graphite powder.

Mining and processing of graphite: Technological advances and environmental challenges

The mining and processing of graphite is a complex and delicate process involving multiple technical links and environmental challenges. As the global demand for graphite resources continues to grow, mining and processing technology is also improving, but at the same time, it also needs to face increasingly severe environmental problems.In terms of mining, with the progress of geological exploration technology, people can more accurately locate the location and scale of graphite deposits, and improve mining efficiency. At the same time, the application of mechanization, automation and other technologies has also reduced mining costs and improved production safety. However, the waste rock, waste water and other wastes generated in the mining process have caused a lot of pressure on the environment, and effective treatment measures need to be taken.In terms of processing, the purification, crushing, molding and other processes of graphite are also constantly optimized. The new purificat

The difference between expanded graphite and graphene

Graphene and expanded graphite exhibit different behaviors in both material structure and application fields. Expanded graphite can be used as a raw material for the production of graphene. For example, the Hummers method can be used to obtain graphene oxide through ultrasonic expansion of graphite oxide. When the expanded graphite is peeled off into a single piece, it becomes graphene. Peeling off into several layers is a few layers of graphene, and graphene nanosheets can be prepared from about ten to thirty layers.Practical application fields of expanded graphite1. Application of Medical MaterialsMedical dressings made of expanded graphite have many excellent properties and can replace most traditional gauze.2. Application of Military MaterialsCrushing expanded graphite into micropowders has strong scattering and absorption properties for infrared waves, making it an excellent infrared shielding material and playing an important role in modern optoelectronic warfare.3.

Characteristics of graphite crucibles

Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance for rapid heating and cooling. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability. Graphite crucibles, due to their excellent performance, are widely used in industries such as metallurgy, casting, machinery, and chemical engineering for the smelting of alloy tool steel and the melting of non-ferrous metals and their alloys. And it has good technical and economic effects. The production of domestic graphite crucibles has reached or even exceeded that of imported crucibles:1. The high density of graphite crucibles enables them to have good thermal conductivity;2. The graphite crucible has a specially made and dense molding material on its surface, greatly improving the corrosion resistance of the product and extending its service life;3. The ther

Analysis of the scope of application of industrial graphite in graphite products

Graphite products maintain the original chemical properties of flake graphite, namely acid resistance, corrosion resistance and physical properties, namely high temperature resistance 3000C and low temperature resistance 204C. Its compressive strength is greater than 800kg/cm2, and it is anti-oxidation. It loses weight in air at 450°C by 1 % , the rebound rate is 15-50% (density 1.1-1.5). It also has strong self-lubricating properties. Therefore, graphite products have been widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics and so on.Using the characteristics of graphite, people have deftly made different types of products according to the needs of engineering: such as high-purity graphite products, flexible graphite products, composite graphite products and so on.

How to distinguish whether Gwangba is clean and tidy?

1. Determine that the graphite boat has no acid and alkali ingredients. (After immersion, you can use pH to detect water or graphite boats that have been used as neutralized to determine the results of the cleaning.)2. Check out the surface layer, graphite guarding point and graphite boat, and whether there are residues of silicon nitride.3. Try the ceramic stick and porcelain sleeve with the dust -free paper -free paper -free paper -free paper.Remarks: The above rules are distinguished under the processing process of all normal washing boats. When the ceramic stick is broken during the whole process of laundering, the insistence is too large, and it needs to be immediately disassembled to prevent everything that endangers the graphite boat. Normal application.

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 application of scales in the casting industry

1. Scales graphite is the main raw material for the casting industry.During the casting process, the scale graphite should be added to the casting, which helps the product to complete it faster and better, and improve the quality of the casting product. Therefore, the scale graphite for casting is the key raw material for the casting industry.2. How is graphite used to cast?Processing the cast -specific scales graphite into powder, and then add it to the outer surface of the casting and casting to make the casting easy to remove the mold. Casting dedicated scales graphite improves the surface quality of the casting, making the castings more abrasion and high temperature. This is the application of cast -specific scales graphite in casting and its abrasion resistance and high temperature resistance.
