Will the performance changes after expanding graphite multiple times?

Expansion graphite exposure will expand rapidly at high temperatures. It has a certain isolation effect and can be used to extinguish metal fires such as lithium, sodium, potassium, uranium, and cricket. It is a good fire extinguishing agent. In actual use, we found that the functional effect of expansion graphite has a lot to do with the number of expansion of expansion graphite. The following graphite manufacturer editor will explain the function of repeated expansion of expanded graphite:The number of expansion graphite determines the role of expanding graphite. The repeated expansion of graphite powder is fluffy powder, which presents a structure similar to a kneading paper ball on the micro structure, but the active point of the carbon layer edges will increase. When making expansion graphite fire extinguishers, the expansion graphite can be expanded repeatedly. When the expansion graphite expands more than three times, the expansion of the expansion graphite is now less than twi

The adaptability of the scale graphite to temperature

Scales graphite is a natural graphite. It is usually a thin piece or scale form. It has a strong adaptability to high temperature and has a strong heat shock resistance. The scale of the scale is added to the production of many products, which enhances the product's ability to work at high temperature. Today, the editor will explain the adaptability of the scale graphite to temperature:Scales graphite has very good high temperature resistance and is one of the high -temperature resistance materials. When higher than 2000 degrees, the general material will appear in a melting state, or it has become a gas, and even some difficult melting metals will lose strength at about 2500 degrees. 3600 degrees, but the scale graphite will not melt at this temperature. The melting point is 3850 degrees.If several high -temperature -resistant materials are placed at 7000 degrees of ultra -high temperature arc for 10 seconds, the losses of scales graphite are extremely small. According to the weight

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

What is the advantage of expanding graphite?

Compared with other adsorption agents, expansion graphite has many advantages. If the activated carbon is used for water removal, it will sink after the absorption of oil. At the same time as absorbing oil, it also absorbs water, which brings difficulty in post -treatment; the expansion graphite has a large absorption of oil, floating on the water after oil absorption, easy to catch and recycled, easy to use processing processing Cleaning, combustion, heating extraction and other methods will not form secondary pollution.
