In the middle of the night, the safes in Wang’s office were smashed, and over 400,000 yuan in cash and antiques valued at more than 1 million yuan were missing. The news comes from China Vault /
Graphite Powder soft, dark gray; greasy feeling, can contaminate the paper. Hardness of 1 to 2, along the vertical direction with the increase in the hardness of the hardness can be increased to 3 to 5. Specific gravity of 1.9 to 2.3. In the isolated oxygen conditions, the melting point of more than 3000 ℃, is one of the most resistant minerals. At room temperature, the chemical properties of Graphite powder is relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; materials with high temperature conductive properties, do refractory materials, conductive materials, wear-resistant lubricating materials.
Graphite powder is widely used, according to its different use, we can be divided into the following categories of graphite powder
1. Scale graphite powder
Flake Graphite powder is the most widely used, but also processed into other graphite powder of the original material, scaly graphite powder specifications from 32 to -12000 mesh range, scaly graphite powder toughness is good, with good thermal conductivity and corrosion resistance, can be used as refractory Materials, wear-resistant lubricating materials, conductive materials, casting, Fansha, die and high temperature metallurgical materials
2. Colloidal Graphite powder
Colloidal graphite is formed by the average dispersion of graphite particles below 2u meters in an organic solvent. Colloidal graphite is a viscous suspension of black filaments. Colloidal graphite powder with high quality Natural Flake Graphite performance, in high temperature conditions with special oxidation resistance, self-lubricating and plasticity, at the same time with good conductivity, thermal conductivity and adhesion, mainly used in sealing, metallurgical stripping and other industries
3. Ultrafine graphite powder
Ultrafine graphite powder specifications are generally between 8000 mesh -10000 mesh, mainly used in powder metallurgy release agent, the production of graphite crucible, the battery anode and make conductive materials additives
Nano-graphite powder main specifications for the D30 50 100 400 nm, nano-graphite powder process is more complex, low production rate, so relatively high prices, mainly used in anti-corrosion coatings, lubricants additives, grease additives, precision graphite seal And other industries, in addition, nano-graphite powder in scientific research institutions also has a high application value

Two months later, the thief was captured by the police.
To Wang's surprise, the thief turned out to be one of his employees who worked for a month.
In order to steal Wang’s money and antiques, Yu Yu has made painstaking efforts. He has “hidden†one month on the side of Wang. After theft, the stolen goods are hidden in a host computer.
The authorities calculated that Yu was captured by the police.
On July 30, the reporter learned from the Linfen police that Yu had already been arrested by the procuratorate.
The safe was vandalized by millions of antiques. On the morning of May 20th, in a logistics company in Lintai District, a staff member at work discussed that the company’s boss Wang Fu’s office had been smashed and lost more than RMB 1 million.
Originally, Wang liked to collect antiques. He scouring the Tibetans and friends from auctions had many good things, including ancient bronze ware, jade, agate, ancient coins, modern jade, jewelry, and jewelry.
In order to collect these things, Wang specifically bought a safe, usually in his own office. When a friend comes to play, he opens his own safe and lets his friends know and understand their baby.
This show brought large robbers, and the antiques and cash in the safe were gone overnight.
A joint investigation by the Linyi Public Security Bureau's Criminal Investigation No. 7 Squadron and the Huantai police station found that the thieves entered the company from 23:30 to May 20th, 1:00 on May 19, and opened the doors of Wang’s office. of. From the analysis of the traces left behind by the crime scene, the thief was familiar with the company's situation. He did not go to the financial office, but went directly to Wang’s office where the safe was stored. Obviously, he knew that Wang had a safe in his office.
A bronze mirror on the Internet pulled out the suspect’s characteristics based on the thief’s goal of going straight to the safe. The police analyzed that the acquaintance’s crime may be relatively large. The Wang’s company’s employees, friends, and the surrounding business operators were investigated.
At the same time, the police visited the collectors and sales staff of some antique markets in Zibo and controlled them from the sales channels. In response to the prevalence of online sales today, the police also conducted investigations on antique forums, websites, and online trading platforms. A large network for arresting suspected burglaries opened.
On July 6, the police discovered that someone sold a bronze antique mirror on a forum called “Quanyuan Garden†with a price of 15,000 yuan. This old mirror resembles the old mirror stolen by the victim Wang. After Wang identified, this is the ancient mirror he stole.
Through the investigation, the police decided to send the information of the ancient mirror online to Dongmou of Suichuan.
The police quickly attacked and arrived in Longchuan to find Dongmou.
At Dongmou’s home, the police found three bronze mirrors and two other bronze utensils. Dong Mou said that the five bronze wares were bought from Yutai’s hand by a person who spent 1.5 million yuan. “Yu confessed to be a dangerous goods vehicle.â€
The police suddenly thought that in Wang’s company, a driver who opened a dangerous goods vehicle was named after the family. Before the incident, Yu had resigned from Wang's company. Before that, he only worked in Wang's company for a month.
Yu has a major suspect!
After a month of leaving the employee to steal the boss, on July 12th, after a few days in the vicinity of a certain home in the Fujian and Taiwan, the police successfully won the arrest.
At this time, in a very calm performance.
Seeing that the police searched their homes and found no stolen items, it seemed to be a little triumphant.
The police did not give up, and they searched again and finally found out in a certain computer bag that Wang was stolen from the Han cloth “(a coin of the Han Dynasty).
The police confirmed that the stolen thing was definitely hidden in a home, but where did he hide?
When moving a host computer in a home, the police found that the computer host was particularly heavy. They took the machine apart and saw that most of the stolen items were hidden in the mainframe.
It turned out that in 1972, Yu was once jailed for six times for stealing and posing as a military fraud. There are more than ten years spent in prison. After his release from prison, Yu Mou believed that he had strong anti-surveillance experience. After inquiring about Wang's collection of antiques, he applied for Wang's company to work. When Wang showed antiques to his friends, he snooped into the location of antique storage.
After working for a month, Yu resigned and he rushed to the opportunity of Wang's business trip. He crossed the wall and entered the company, opened the safe, stole antiques and cash.
