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.

Application and Introduction of Graphite Pillars

The graphite column combines the wear resistance of copper alloy and the self-lubricating performance of solid graphite lubricant, making it unnecessary to refuel and maintain during use. The product is widely used for high load, intermittent or swinging movements, such as production lines for steam locomotives, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the operating conditions used, various types of copper alloys can be provided.The main component of graphite column is graphite, and its performance is different from that of ordinary graphite1、 The production and processing technology characteristics of graphite pillars:1. High temperature resistance: Graphite is currently one of the most high-temperature resistant materials known. Its melting point is 3850 ℃± 50 ℃, and its boiling point reaches 4250 ℃. It is subjected to an ultra-high temperature arc at 7000 ℃ for 10 seconds, with the smallest loss of graphite, which is 0.8% by weight. From t

Natural graphite classification

The dense crystal graphite is also called block -like graphite. Such graphite crystals are obviously visible to the naked eye. The diameter of the particles is greater than 0.1 mm, which is concentrated in 0.1-1m/g than the surface area. This graphite is characterized by high quality. Generally, the carbon content is 60-65%, and sometimes 80-98%, but its plasticity and slipperyability are not as good as scales.

Immersion graphite

Plug -in graphite, also known as immersive graphite or immersion immersion graphite. Category of non -transparent graphite.Immersion graphitePinyin: jinzishimoEnglish name: ImpregNated GraphiteNote: Use synthetic resin to penetrate graphite to fill its surface and internal pores, and then make the heat treatment to curing the resin and make it. Compared with graphite, mechanical strength is improved and thermal conductivity is unchanged. With the difference in penetrating resin, there are different varieties such as phenolic graphite and bran glycoling graphite.

What is the purpose of expanding graphite

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.

What are the characteristics of high-purity flake graphite

High purity flake graphite has good high-temperature resistance, conductivity, thermal conductivity, lubricity, and chemical stability. Graphite powder manufacturers are widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, fire protection, electronics, medicine, military industry, aerospace, etc. It plays an increasingly important role in the national economy and is an indispensable non-metallic raw material for modern industrial and high-tech development. Trace impurities have a significant impact on the performance of graphite products. The higher the carbon content of high-purity flake graphite, the better its performance as a functional material.In order to analyze trace impurities in high-purity flake graphite, the sample is usually ashed or wet digested to remove carbon, the ash is dissolved in acid, and the impurity content in the solution is then determined. The ashing method does not require the use of ultrapure acids to dissolve a

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.

Pulse graphite

As early as the 1930s, China Heilongjiang Jixi Liu Mao and Shandong South Villa Genti Mine began production and processing of pulse graphite. At that time, the mining process was simple, the workers had poor labor conditions, the productivity was extremely low, and the annual output was only thousands of tons. After decades of development, the output of mulberry graphite and carbon products in my country has risen rapidly. From 2004 to 2011, the compound annual growth rate of pulse graphite and carbon products reached 22.12%. In 2011, the output of my country's pulse graphics and carbon products was 25.5617 million tons, an increase of 21.98%year -on -year.Pulse graphite and carbon products have excellent performance, which are increasingly widely used, and production capacity and efficiency are growing rapidly. In 2011, the Chinese pulse graphite and the carbon products industry developed rapidly, and the industry in the industry had high management and control capabilities in cost a
