The formation of fluoride crystal mica is a sub-grade, and does not adsorb impurities. It was selected by the Chinese Academy of Sciences Environmental Biology Research Center Peking University, Tsinghua University, Shanghai Fudan University, Nanjing University, and more than 100 national research institutions and universities for Afm Substrate After (microscopy carrier wave), the relevant person said: Compared to natural mica, fluorite mica has better flatness and less adsorption impurities. The images observed in the analysis of the DNA structure, especially in the 1 nm to 100 nm scale, have observed surface interference fringes not found in the natural mica experiment, which are clearly dozens of times better than the natural mica Substrate. Experts involved in the experiment believe that the use of fluoride mica instead of natural mica as a substrate material is expected to catch up with the international level.

One day in August 2003, five kilometers east of Kuche County, on the south side of National Highway 314, colorful flags fluttered and gongs were heard. The first large-scale fertilizer project in southern Xinjiang was started here. The Uighurs, who have served for generations in the local area, looked around and looked around. What should be done here?
More than two years later, November 22, 2005, Cheng Yaoming, executive deputy chief of the Aksu Huajin Chemical Fertilizer Engineering Command of Liaoning Huajin Chemical (Group) Co., Ltd., told reporters: 'Huajinda Chemical Fertilizer Project is a key project in Xinjiang. , is the largest project for foreign investment in Aksu region. The urea needed in the southern Xinjiang region is only insufficient for the nitrogen fertilizer company Zep Fertilizer Plant in the region. Because of the inconvenience of transportation, the urea in the northern Xinjiang and the Mainland is not easily transported to southern Xinjiang. Since the discovery of abundant natural gas in southern Xinjiang, the government of the autonomous region and Aksu Prefecture have been considering building a large-scale urea plant. Therefore, when the National Development and Reform Commission approved the establishment of this large-scale fertilizer plant in early 2002, the Aksu Prefecture government included it in the No. 1 project. '
The Aksu Hua Jinda Fertilizer plant is a part of the 300,000-ton synthetic ammonia and 520,000-ton urea plant of the Guangzhou Petrochemical General Plant under the China Petrochemical Corporation and part of the Huajinda Chemical Fertilizer Plant. These two large chemical fertilizer plants were the first of 13 big fertilizer plants introduced by Premier Zhou Enlai in 1973. Not because they could not be used for a long time, but because the raw material problems of oil heads and gas heads could not be reused. intact.
Since it is demolition and transportation before installation, the difficulty of construction is naturally much greater than that of newly purchased devices. Because the two sets of devices were introduced 30 years ago, after many technical transformations, the devices themselves are very different from the drawings that came with the device. It is very difficult to re-assemble it and reassemble it as it is. Xu Jian, deputy general manager of the China Chemical Engineering 9th Construction Company and manager of the Kuqa Project Department who participated in the construction, said: 'Fortunately, Jiuhuajian and Huajin Group are old friends who have supported each other for many years. In the construction of the Ninth Five-Year Development Project, although the drawings can not explain the situation of the installation, our employees still completed the demolition and re-installation with many years of experience and reference to those drawings of the year. In addition, Aksu's large chemical fertilizer is already the fifth large-scale chemical fertilizer plant built by us. Experience is very important. It is based on the knowledge and diligence of our nine engineering and technical personnel and workers. '
The project was due to demolition, so the cost is relatively low. The old device does not count, cash investment of 800 million, plus the purchase of some new equipment, the total cost of only 1.1 billion. For a device of the same size, the total investment in the project will not be less than RMB 2-3 billion. This is very important for the western region.
Although the first large fertilizer plant in Ningxia was relocated from Europe, it was rebuilt. However, after the demolition of the two large-scale chemical fertilizer devices, they will be combined into a large-scale chemical fertilizer device, which is the first time in the world. Even the experienced Jiuhua Construction has made painstaking efforts. The dismantling of all the old devices is conducive to transport, but some devices are a whole, such as urea synthesis tower, 28 meters high, 98 tons, can not be separated, can only be removed to a certain extent. From Huajin Group in Panjin City, Liaoning Province to Kuqa County, there are more than 5,000 kilometers of roads and the road conditions are complex. To this end, Jiuhua Jian first dispatched car exploration roads to ensure the safety of large-scale installations during the half-monthly transportation process. In the past, it took at least two and a half to three years to build a large-scale fertilizer plant. Jiuhuajian built the Aksu Huajinda fertilizer project in just one year and eight months.
At 9 o'clock on the evening of November 9 this year, a section of the gasifier of the synthetic ammonia system was successfully ignited, marking the completion of the device and entering the trial phase. At present, the Aksu Huajin Chemical Fertilizer Plant is undergoing final purging and is expected to produce urea in mid-December.
The Aksu Hua Jinda Fertilizer Project fills the gap of large chemical fertilizers in southern Xinjiang and has become the starting point for large-scale industrial projects in southern Xinjiang. After the completion of the project, Huajin Chemical Group will become the largest and most competitive enterprise with large chemical fertilizer facilities in China. Jiuhuajian will also establish a branch company in southern Xinjiang and continue to expand its business scope. This is also the revitalization of the old industrial enterprises in the northeast region. One of the ways and measures.
The No. 1 Project on the Ancient Silk Road --- Aksu Hua Jinda Fertilizer Engineering Project of the "Tenth Five-Year" Key Project
The Kuqa County to the north of the Taklimakan Desert in the southern part of the Xinjiang Uygur Autonomous Region is a must-have place on the historically famous ancient Silk Road. It is also the capital of the ancient Turtles and the industrial base is very weak.
