Recently, Nanjing Jiangning police caught a "cockroach" thief. He tried his best to steal a safe from a shop owner, thinking that there was a huge sum of money inside. Afterwards, in order to open the cabinet, he took great efforts to find a cutting machine. However, after intercepting the safe, he found that there was a total of only 535 yuan. money. The thief gasped "half dead" and was quickly arrested. According to the police station of Jiangning High-tech Park, the owner of the Zhangye Yiwu Small Commodity Market came to the store the day before yesterday. He was prepared to open the door to do business and found that the shutter of his own shop had been knocked out of a hole. Zhang Bo quickly went in and saw that the house was in a mess and the safe in the office was gone, so he immediately called the police. The police rushed to the scene to investigate and found that the thieves had also stolen the monitoring inside the store. Who is doing it? Zhang boss reported that he had a suspected object: “Is it the customer who owes me two thousand dollars? At 6 o'clock in the afternoon yesterday, he sneaked around in my shop for a few laps.†Zhang boss said that the surname was The customer of the horse said that when he had paid his wages, he repaid the money and asked him for a business card. At the time, he answered the phone and put the workers' wages in the stolen safe. However, when Zhang boss returned home from work at night, he took tens of thousands of dollars from the safe and took more than 500 yuan in the safe when he was stolen. The police discovered that this mysterious customer, Ma, was released on bail in January this year. He is very suspect. Ma was quickly arrested by the police. According to Ma, his own payroll card has been kept in his wife's hands, and his wife has recently been asked for money and refused, and she is ready to steal some tiles and toilets in the nearby market to sell money. After strolling around the commodity city with a car, Ma found that the decoration shop that he owed money had a roller shutter door open. He walked past and walked in and found that the light inside was lit, and the drawers of the cabinet were turned over. There was a mess, but there was a safe on the desk. It seemed that before he had a thief, he tried to open the safe but did not open it. Ma decided to move the safe out and find another place to open it, and later stole a cutting machine nearby. He took the safe and cutting machine and spent a long time cutting the safe in half with a cutting machine, but was disappointed to find it was only RMB 535. Ending: Going home the next day was arrested Then he felt depressed, and he threw away the safe, burned the documents in the safe, and then drove the motorcycle back home. He did not expect to be captured by the police the next day. At present, Ma has been under administrative detention. The police are currently investigating another thief who he reported was burglary.

Flake Graphite is a natural crystalline Graphite . It is shaped like fish phosphorus, and is a six-square crystal system. It is layered and has good properties of high temperature resistance, conduction, heat conduction, lubrication, plasticization and acid and alkali resistance.
Flake graphite is a natural solid lubricant of layered structure, rich in resources and cheap in price.
feature
The flake graphite crystallization is complete, the film is thin and the toughness is good, the materialized performance is excellent, has the good thermal conductivity, the conductivity, the thermal shock resistance, corrosion resistance and so on.
distribution
In December 2015, geological prospectors found a large scale graphite mine in alashan, Inner Mongolia. The total amount of graphite resources was 1. 300 million tons, about 7 of the world's recoverable reserves. 3%, average grade 5. 45%. According to the introduction, such high grade, large-scale Graphite Mineral deposits are rare in China. [1]
In 2013, the U.S. geological survey reported that the global scale of graphite minerals was less than 5 million tons. The discovery was made in alashan, which has a large scale of 703 million tons of graphite in the area of zahan mushi.
classification
Classified according to the carbon content
Like C %, 99.9% High Purity Graphite; Ninety-four percent of "C %" is High Carbon Graphite; 80% "C %" is Medium Carbon Graphite; 50% "C %" is low Carbon Graphite .
Classification by size of granularity
When the particle size is smaller than w38 micropowder graphite.
standard
Scale graphite standard GB T 3518-2008

refractory
Flake graphite is widely used in the treatment of gold industry of advanced refractory materials and coatings. Such as magnesia carbon brick, crucible, etc. Military industrial firework material stabilizer, smelting industrial desulfurization growth agent, light industry lead pen, electric industry carbon brush, battery industry electrode, fertilizer industry catalyst and so on. The flake graphite is deeply processed, and it can produce the graphite milk for lubricant, deformable agent, drawing agent, conductive coating and so on. It can also produce Expanded Graphite for flexible graphite products such as flexible graphite seals and flexible graphite composite products.
dope
The flake graphite as the functional filler of coating is mainly used for anticorrosive coating, fire retardant coating and conductive coating.
As an anticorrosive material, it has anti-rust primer, such as carbon black, talcum powder and oil, which has good corrosion resistance of chemicals and solvents. If you add zinc and yellow to the formula, it is better to rust.
A graphite interlayer compound obtained from Natural Graphite scales as raw materials, chemically or electrochemically treated. Expandable graphite under the condition of heat, swelling volume (up to 300 times) suffocate the flames, at the same time generate inflation, to isolate the flame, delay or interrupt the effect of flame spread, and itself does not burn, good flexibility, high surface energy, intensity of carbonized layer. But the volume and dosage of the expansive body should be suitable. The test shows that the 150um particles, 30% expansion multiples and 5% dosage are the most suitable.
The flake graphite can be directly used as a carbon conductive filler and can be made into a composite conductive filler for conductive coatings. However, due to the large addition of graphite flake, the coating can be brittle and its application is limited. Therefore, measures are taken to further improve the conductivity of graphite and effectively reduce the amount of graphite flake. Our domestic chemical machinery research institute has developed a high temperature and corrosion resistant resin as basic material, with the strong ability of conducting electrostatic entities large flake graphite flake as the main aggregates, with high intensity of ontology Good abrasion resistance.
The anti - deformation cracking - good short - cut fiber material is a solvent - free thick film conductive coating. The coating has the characteristics of anti-corrosive media penetration, small residual stress, good anti-matrix deformation, stable construction performance and long - term conductive static. Can be used in oil tank inner wall guide electrostatic coating. With electroless plating technique, according to the data of graphite powders metallized, such as copper, nickel, silver, such as the preparation of composite conductive filler, with 30% of the amount used in conductive coating, not only its conductivity is very good, and further improve corrosion.
