"A large number of experiments, constantly trying, aiming at the problem of comprehensive use of phospholosypsum, we have been working hard to break through." On September 8th, Chi Ruan, director of the Laboratory and Professor of Wuhan Engineering University in the Three Gorges Laboratory of Hubei Introduction, the six major research directions of the six major research directions of phosphorplasyum comprehensive utilization, key chemicals of microelectronics, high -end chemicals of phosphorus, silicon system chemicals, new energy materials, chemical efficiency equipment and intelligent control, basic research and application basic research in laboratory The research and development of key core technologies of industrialization is being promoted.

Innovate an attempt to open a new field of vision

"This is the phosphololic gypsum of 'grinding people'." In the R & D Center of Phosphorol Pyropheds in the Three Gorges Laboratory, researchers were busy in front of the experimental instruments, only to find this "gray earth" better treatment method.

Why is the phosphopide "grinding people"? As the main component of phosphorus fertilizer in agricultural production, phosphorus is directly related to the yield and quality of crops, and phospholosaclene is a "by -product" that is accompanied by phosphate fertilizer. Chi Ruan introduced that phosphate is one of the raw materials for producing high concentration of compound fertilizer. For each 1 ton of phosphate, it is necessary to produce 4.5 tons to 5 tons of phosphopide. At present, there are 300 million tons of phospholosypsum in Hubei Province, accounting for more than 45%of the country's stacking volume, and will grow at a rate of 20 million tons per year. However, such a huge amount of "waste slag" utilization is about 40%. Most of the phospholosaclene can only be treated in a "stacking" method. Sustainable development brings tremendous pressure.

What are the ways to deal with phosphide? The Researcher of the Three Gorges Laboratory introduced that the "water washing and mineralization" technology walked out of the laboratory in June and then launched in the factory area. The biggest feature is "simple and effective". After washing the phosphopide through water, the soluble phosphorus and fluorine in the water washing solution was recovered, and the mineralized agent was added to the filtrate after washing. Simple, but the team has spent nearly 3 months of check -in, just to find the most suitable way. " In addition, the comprehensive utilization path of phosphide also includes road base materials, phosphide alcohol modified filling area, etc. The industrial gypsum can also be widely used in building materials and decorative materials.

In the laboratory full of bottles and cans, the green side of the window is particularly noticeable. "We are making some new attempts in the laboratory, such as the soilization of phosphide gypsum." He said that the soil of planting peanuts and rye grass was treated, and the phosphorus and fluoride in the phosphopide were precipitated. After reaching neutral, after adding humic acid, the soil becomes more fertile and more suitable for plant growth. In addition, after the efforts of the team, the purity of calcium sulfate in phospholosifying is nearly 98%after purification, and the recovery rate can reach more than 90%. In addition, calcium sulfate is the main component of gypsum. After some treatment, it can be comparable to natural gypsum. It can not only be used as basic building decorative materials, but also high -strength gypsum can even be used to print and repair human bones and make plaster bandages.

At present, phosphate resources in our province have reserves, annual mining volume, scale of phosphate chemical industry, and phosphate fertilizer production in the country. The phosphorus chemical industry involves all fields of industrial and agricultural industrial and agricultural industrial and agricultural industrial and agricultural industrial and agricultural industrial and agricultural industrial and high -quality development. However, for a long time, due to the lack of correct understanding of the pollution environment of phospholosypsum, the amount of harmless treatment and comprehensive utilization rate of phospholosypsum is low. "The comprehensive utilization and harmless treatment of phospholoside is a world -class problem. How to" eat dry and squeeze "phosphopide will be the long -term research focus of the Three Gorges Laboratory." Chi Rian said.

"Silicon direct chloride" energy consumption decreases by 30 %

In addition to the comprehensive utilization of phosphide gypsum, the basic chemicals of silicon are also one of the important research directions of the Three Gorges Laboratory.

"Silicon -based basic chemicals are quite widely used." In the Three Gorges Laboratory, Hubei Xingfa Chemical Group, Chi Ruan introduced to reporters that the sealing glue used in the field of space is small, as small as a silicone bowl used in daily life. Silicon -based basic chemicals are everywhere. Generally speaking, methyl chloride is the raw material of organic silicon products. During the production process, it will generate chlorohide polluting atmosphere. At the same time, it consumes huge energy consumption.

Professor Lu Renliang, a professor of Wuhan Engineering University, is a "dual -hiring" professor of the Three Gorges Lab. His research project "Research and Development of Silicidation of Silicidation of Silicon and Alkylated Silication" is used to solve "high pollution" and "high energy consumption". The problem. Lu Renliang said that this research technology can directly convert silicon -containing raw materials such as sand into organic silicon through catalysts. As a raw material, the high energy consumption and high pollution are skipped.

"Green is the background." Chi Rian said. The Three Gorges Laboratory focused on the field of green chemical industry. The development of modern chemical trillion industrial clusters has improved the core competitiveness of my country's modern chemical industry.

It is understood that the Three Gorges Laboratory leading unit Xingfa Group budget 870 million yuan has launched four major types of projects, including 1 of more than 100 million yuan, and 16 major projects of more than 10 million yuan. In the first half of this year, the laboratory published 40 scientific papers, including 34 SCI papers, 6 Chinese core papers, and 1 monograph on "Phosphor Pypsum" in Science Press; Use the "two key R & D plan projects, apply for 17 patents for invention, and strive to achieve the new output value of the service chemical industry 100 billion yuan in the three -year construction period. In the next three years, the laboratory will break through the key core technologies of key chemicals, phosphorus -based high -end chemicals and new energy materials, create leading silicon -based basic chemical production technology, extend and deepen the industrial chain; strengthen the green chemical industry of the industry In the process, a major breakthrough in the comprehensive utilization of phosphide gypsum; the integration system of chemical equipment and intelligent control in the above -mentioned fields, and creating a chemical industry cluster with high -quality development; Innovate highlands, the collection base of outstanding chemical talents, and provide technical support for important fine chemical centers in the world.

The Hubei Daily client, paying attention to the major events of Hubei and the world, not only pushing the authoritative policies for users, fresh hot information, and practical convenience information, but also launched a series of features such as reading newspapers, newspapers, learning, online interactives.
