The lubrication of sliced graphite is mainly reflected in two aspects

1. Silver-like Gention-Environmental atmospheric lubricationThe essence of lubrication of sheet -like graphite is its laminar crystal structure. The initial raw materials for preparation of expansion graphite are high -carbon -like graphite. Other chemical reagents such as concentrated sulfuric acid (more than 98%), hydrogen peroxide (more than 28%), and potassium permanganate are industrial -grade reagents. The general steps of preparation are as follows: At the appropriate temperature, add different proportion of hydrogen peroxide solution, natural scales and concentrated sulfuric acid to different programs, react for a certain period of time under continuous stirring, and then wash to neutrality, centrifugal, dehydrated, and dehydration. Dry vacuum at 60 ° C.2. Film graphite-solid lubricant and lubricant additiveThe lubrication performance of slices graphite is also affected by graphite particles. Some research and test results show that whether it is a natural piece of graphite or

Insufficient technical investment in domestic graphite powder production enterprises

As a policy of each graphite deep processing production company, it is far from reality. The single product function is not bad, but the stability of batch production is doubtful, and the consistency of each batch of products cannot be guaranteed. A professor of deep processing and production of graphite powder believes that the exchanges of different types of different types of information for the deep processing and production of graphite powder will be a long process. The gap between many companies is that they have excellent experiments but cannot produce in batches. The following editors analyze the reasons for the lack of technical investment in domestic graphite powder production enterprises:It is not related to the automation control of the company's production line, which is a systematic problem. At present, graphite powder deep processing production equipment accounts for more than half of the imported equipment. Graphite mineral resources are a very important strategic reso

The black PCB is difficult to see the wiring clearly, which brings difficulties for maintenance

From this point of view, the color of PCB has nothing to do with the quality of PCB. The difference between black PCB and blue PCB, yellow PCB, etc. The difference between PCB is different in the color resistance paint color. If the PCB design and manufacturing process is exactly the same, the color will not have any impact on performance, and it will not have any eff

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
