Considering that Wei Jianguo would come forward to entertain Liu Chi in the evening, Zhao Changfeng was not reluctant, and gargled with some beer, which meant a little. 【Fengyun Reading Network. 】

Since he didn't drink liquor, and Liu Chi had something on his mind, lunch ended in less than an hour. Dong Jinkun and Mo Rigen knew that County Magistrate Xiao Zhao must have something to say to their hometown, so they complained to Liu Chi, saying that they still had some work to deal with, and they would accompany Secretary Liu and Mayor Gao to enjoy themselves in the evening.

Zhao Changfeng accompanied Liu Chi to Xiaozhao's luxury suite. Zhang Yilei made two cups of tea for Liu Chi and Zhao Changfeng, and then exited the room with interest, leaving a space for Liu Chi and Zhao Changfeng to talk.

Gao Shengqiang was also interested in leaving, but was stopped by Liu Chi: "Old Gao, you stay." Gao Shengqiang smiled bitterly at Zhao Changfeng, so he had to sit on the sand.

"Brother Changfeng, taste the smoke of your hometown." Liu Chi took out a pack of Emgrand Guofeng, gave one to Zhao Changfeng, and then said to Zhao Changfeng straight to the point: "Brother Changfeng, I am here to ask you for help this time." ”

Zhao Changfeng had already gotten the purpose of Liu Chi's coming over from Gao Shengqiang, but at this time, he pretended to be confused and said with a smile: "Secretary Liu, you are polite." If there's something you can say, as long as I can help, I won't refuse. ”

"It's still interesting to be Brother Changfeng!" Liu Chi moved his body slightly to Zhao Changfeng's side, "I'll just say, it's beautiful, it's beautiful, hometown water; Kiss or not, hometown people. Although Brother Changfeng came to eastern Guangdong, his roots are still rooted in our north, do you say, Lao Gao? ”

Gao Shengqiang smiled secretly in his heart, but he had to match Liu Chi's words, and nodded again and again: "Secretary Liu, what you said is right, the mayor will never forget our Beibei no matter what." ”

Zhao Changfeng's last position in Bibei City was deputy secretary and executive deputy mayor, and Zhang Yilei was the director of the Municipal Party Committee Office, so he naturally called Zhao Changfeng Secretary Zhao according to the habit of the Municipal Party Committee. Gao Shengqiang is a member of the municipal government, and of course Zhao Changfeng is called mayor according to the name of the municipal government.

Zhao Changfeng had a reserved smile on his face. Quietly smoked and did not speak.

"Brother Changfeng, I told you two days ago, I went to Hong Kong to deal with the bankruptcy and liquidation of Riyadh Group." Liu Chi looked at Zhao Changfeng and said.

"Secretary Liu. What happened to the results? Zhao Changfeng asked with concern.

"Alas. It's not ideal. Liu Chi shook his head. "We argue with reason. In the end, it was just a matter of getting the Riyadh Group to produce what neodymium ......," said Liu Chi and looked at Gao Shengqiang with his eyes.

Gao Shengqiang reminded in a whisper on the side: "NdFeB." ”

"Yes. NdFeB. Patent for the production of NdFeB permanent magnet materials. Liu Chi said to Zhao Changfeng.

"Permanent magnet material? This new material production technology is very popular in the world. Zhao Changfeng said with a smile: "Secretary Liu." This time, our city in Pibei can be a blessing in disguise. hugged a golden doll, and Zhao Changfeng said it was good. Permanent magnet materials are indeed very sought-after new materials in the world. In particular, NdFeB permanent magnet materials. It is also a permanent magnet material with the most potential to emerge in recent years. Two days ago, Gao Shengqiang secretly called Zhao Changfeng to tell him the news. Zhao Changfeng also specially asked Bao Xiaofei to collect the latest permanent magnet material and give it to him.

Permanent magnet material is actually a kind of strong magnetic material. Strong magnetic materials refer to geomagnetically ordered materials that have ferromagnetism or ferromagnetism and have practical application value. According to the application type, it can be divided into two categories: permanent magnet and soft magnetic materials. Permanent magnet materials are also known as hard magnetic materials. After magnetization of the external strengthened magnetic field and the removal of the external magnetic field, a high residual magnetic property can be retained for a long time. And it can withstand the interference of other environmental factors that are not too strong applied magnetic field. At present, the application of permanent magnet materials is based on their composition and magnetic properties. It can be divided into four categories: rare earth permanent magnet materials, metal permanent magnet materials, ferrite permanent magnet materials and other permanent magnet materials.

Rare earth permanent magnet materials were only developed in the sixties of the last century. So far, three generations of materials have been produced by graduate students. The first generation is smco5 series materials, the second generation is sm2CO17 series materials, and the third generation of permanent magnet materials is NdFe series materials that came out in 1983. This is the first high-performance utility model permanent magnet material without CO. Since its inception, it has been exhibited quickly.

As a new type of permanent magnet material, NdFeB permanent magnet material has a wide range of uses.

First of all, the application of the mobile communication market, most of the sound devices and call devices of mobile phones are made of NdFeB devices, with the continuous popularity of mobile phones, the demand for NdFeB, a new type of permanent magnet material, will be increasing.

The second is the application of the computer market. NdFeB permanent magnet materials are also very widely used in computer applications. Not only the multimedia audio materials of computers need to use NdFeB permanent magnet materials. Moreover, there is a greater demand for permanent magnet materials such as NdFeB for computer peripherals, such as hard disk drives, floppy disk drives, etc. Even printers require high-grade NdFeB permanent magnet materials.

The third widespread use of NdFeB permanent magnet materials is in the automotive industry. Basically, every car needs to use a permanent magnet motor, and a few cars need seventeen or eighteen. An extra car requires more than 30 or even more than 40 permanent magnet motors. In the past, the permanent magnet motor used in automobiles was called ferrite permanent magnet material, but with the progress of the automobile industry, the permanent magnet motor of high-end automobiles has begun to be made of NdFeB permanent magnet material, and gradually to the trend of low-end cars. According to the world's automobile production, the demand for NdFeB permanent magnet materials is a very staggering figure.

The fourth use of NdFeB permanent magnet materials is in the consumer electronics market. This includes digital audio equipment cd, Vd, dVd, mp3, digital video cameras, digital cameras, etc., all of which require a large number of high-performance NdFeB materials.

Just from the analysis of these four types of markets, we can see how broad the market demand for NdFeB, a new type of permanent magnet material, is.

In addition, from the perspective of the production and market distribution of NdFeB permanent magnet materials in the world, Japan and the United States occupy the top two in the world in the production and promotion of NdFeB permanent magnet materials, and these two countries are also the world's largest permanent magnet markets.

As far as Japan is concerned, there are more than 60 manufacturers engaged in the scientific research and development and production of permanent magnet materials, among which Sumitomo Special Metals Corporation of Japan is the world's largest manufacturer of sintered NdFeB permanent magnet materials. In addition, the production of NdFeB from Japan's Shin-Etsu Chemical Industry Co., Ltd. and the production of NdFeB permanent magnet materials from Japan's Tdk Company are also very rapid, and there is a trend of catching up with Japan's Sumitomo Special Metals Company. In addition, there are a number of companies in Japan that are engaged in the research and development of patents for the production of new NdFeB materials.

The United States is second only to Japan in the production of permanent magnet materials, with a total of more than 40 manufacturers, but the production capacity of these more than 40 manufacturers cannot meet the demand for permanent magnet materials in the American market, and a quarter to one-third of the annual demand in the United States depends on imports to meet it.

In addition to Japan and the United States, there is also a huge demand for new NdFeB materials in the European market, but there are very few manufacturers of NdFeB permanent magnet materials in Europe, and most of them need to be imported from other regions.

Speaking of which, we also need to talk about two other characteristics in the production of NdFeB permanent magnet materials.

The first is the technical patent of NdFeB permanent magnet material. At present, the technology patents are mainly in the hands of Japanese and American companies. The international NdFeB permanent magnet material market is therefore divided into a patent market and a non-patent market. Among them, Europe, the United States and Japan are patent countries, the United States and Japan are the main producers and demand countries, and the non-patent market is mainly concentrated in East Asian countries and regions such as South Korea, Taiwan, and Hong Kong, where the electronics industry is reached, and its price and demand cannot be compared with the patent market. To enter the patent market, you need to buy patents from manufacturers with patented technology, and take a certain percentage of the sales revenue from the rake.

Second, the production of NdFeB permanent magnet materials has an obvious dependence on the upstream industry, 80% of the world's system resources are concentrated in Huaxia, and the rare earth resources of Huaxia are mainly concentrated in Yanbei Province and Jiangxi Province, if there are no domestic rare earth resources, Japanese and American companies can not produce NdFeB permanent magnet materials even if they have production patents.

Riyadh Group is actually a regular company, and Chairman Wang, chairman of the board of directors of Riyadh Group, is a businessman with a very keen strategic vision. Because of the production of auto parts, Chairman Wang keenly saw the huge business opportunities in the new NdFeB permanent magnet materials, so he invested heavily in the company's efforts to hire Chinese scientists in the United States and Japan to study the production technology of new NdFeB permanent magnet materials. However, Chairman Wang made a mistake, that is, he did not correctly estimate the strength of the Riyadh Group, and the research of new NdFeB materials requires a large amount of investment, which is far beyond the scope of the Riyadh Group. Therefore, Riyadh Group did not support the new production patent of NdFeB permanent magnet material when it came out, it was bankrupt, and they spent a lot of money on the research of the new production patent is actually a semi-finished product, and now the production patent obtained by Bibei City from the bankruptcy liquidation of Riyadh Group is such a semi-finished product, and it is necessary to continue to invest a huge amount of money in order to turn this semi-finished product into a finished product, and the most critical one is that even if a huge amount of money is invested, no one can guarantee whether it can see results.

So when Liu Chi heard Zhao Changfeng say that Bibei City brought back a golden doll, he couldn't help but smile bitterly.

The second more is delivered. Book lovers have been waiting for a long time
