The cosmetics you use contain this "soil"?

Put a pile of inconspicuous soil red or gray -white clay under the microscope. You can see a stick -shaped crystal tightly and parallel to form a stick -like bundle, with a regular multigenic needle -shaped structure. Crystal beams are mixed with other minerals and accompanied each other.

This is the uneven rods called "the king of thousands of soils and the soil of universal". What are the uses? What kind of "magic" is there? Let's take a look together!

From the first discovery of Russian scholars in 1862, to the United States began to develop and utilize in the 1930s, and to discovered large mines in Liuhe, Jiangsu, my country in the 1970s. Its unique collagen properties and high adsorption, slow release, and discoloration capabilities such as scattered, bonding, thickening, saline -resistant and saline -resistant, etc., in chemical, medicine, environment, new materials, agriculture and animal husbandry, building materials, oil, metallurgy, metallurgy, metallurgy, metallurgy, metallurgy, metallurgy , Food, Cosmetics and other areas have widely used applications, so it is called "the king of thousands of soils and the soil of universal".

Liu Weisheng, a professor at the School of Chemical and Chemical, Lanzhou University, who has been engaged in inorganic chemistry and rare earth chemistry for a long time, Liu Weisheng, director of Lanzhou University Green Materials Research and Development Center, has focused his attention to this. Green agriculture and high value -added industrial products.

New Hope of Green Agriculture

Can ore also become "fertilizers"? Less dangers for cycle! See how to help green agriculture!

Backbuite Mine in Baiyin City, Gansu

Bright, simply a natural one -dimensional nano -grade material.

my country has great advantages, mainly distributed at the junction of Gansu and Jiangsu and Anhui. The uneven rod stigma ore discovered in Gansu is mainly concentrated in Zhangye and Silver. It has now been proven that the resource of the hybrid and the convex rod ore ore is 1.35 billion tons, and the long -view reserves reached 4.4 billion tons, accounting for half of the world's reserves. above. The disadvantage of Gansu's uneven sticks clay mine is relatively low taste and many accompanying mines. The advantage is that it is rich in trace elements, which is more suitable for the development of green agriculture.

Note that the superb adsorption, slow release ability, and the influence of the accompanying mines were noticed. In 2005, Liu Weisheng decided to start with the most basic purification, activation, superimization, and functionalization.

He brought the collected samples back to the school. By heating, microwave, ultrasound, stirring, and activation agent, the uneven rod was parsed from other accompaniment mines, so that the 1 gram of the convex rod is compared with the surface area of ​​120-200 square meters. So big.

Liu Weisheng further discovered that the uneven rods in the Gansu mine belt are rich in 19 trace elements such as iodine, selenium, zinc, boron boron, and mix the activated uneven rod fertilizer in the soil. It can be released slowly when the soil is lacking, and it can be released slowly. Trace elements will not bring any side effects to the soil and crops, and realize the recycling of resources from the soil to the soil.

Since the uneven bars are so good, what is the use of it? How to maximize the role?

Ruka Bang Fertilizer Potato Field Test Demonstration Field

In 2007, the research team and the Lanzhou Separation Science Research Institute jointly declared the "Fund Fund Project of Agricultural Science and Technology Achievements" - "Development and Demonstration Promotion of Multifunctional Ecological Fertilizers" The central cooperation was conducted to conduct the large -scale and standardized scientific experiments of uneven rod fertilizer for crops.

In the experimental fields in Zhongchuan Town, Yongdeng County, Lanzhou City, and Heping Town, Dingyuan Town, Yuzhong County, bumps and potatoes, and other vegetables, they grow together. After the first season of dishes mature, the results are happy: the agricultural product is water -saving and fertilizer, the output is increased, and the content of trace elements is higher.

Wuwei City, Gansu Province Sannong Xinqing Environmental Protection Technology Co., Ltd. 100,000 tons of bumpy rod fertilizer production line

In 2009, the research group and Xinqing Qingqing Environmental Protection Technology Co., Ltd. jointly formed a production, academic, research and development team to develop a new generation of three -dimensional ecological fertilizer for "mineral trace elements+organic matter+microorganisms group". A number of enterprises are produced in batches, and there are more than ten provinces and cities including Xinjiang, Shaanxi, Sichuan, Shandong, Henan, Hunan, Yunnan, Jiangsu, and Heilongjiang joining and promoting promotion. Related products have obtained the "2015 World Expo Kip International Pavilion Special Special Special Organic Agricultural Products" and "2015 World Expo United Nations Garden designated organic fertilizer". Members of the council agreed that the project reached the international leading level in similar products, and it is recommended to increase the application. In the same year, the achievement won the first prize of scientific and technological progress in Gansu Province.

After many years of field trials, Thailand Zhengda Group determined that the average production of fruits and vegetable crops using this fertilizer was increased by 5%-15%, and trace nutritional elements iodine, selenium, and zinc increased by 30%to 3 times. 1.5 times. Potatoes increased by 5%-20%, the product rate increased by 25%, and nearly 40%of the fat savings. Grain crop corn protein was raised from 9%of the national standard to 10.38%.

Related application projects of Rukang Stone not only won many honors and attention for Liu Weisheng's team, but also catering to the development needs of the country's development of green agriculture and ensuring the safety of food security.

In November 2020, at the 22nd China International High -tech Achievement Fair, Liu Weisheng's team developed the "Real -Rand Stone Industrialization Application Project" and "Rukong Stone Baseball Bente soil improvement agent" as the recommendation project of Lanzhou University. At the Shenzhen Innovation and Entrepreneurship Investment Conference held in 2020, the "Application of Burieving Stone Stone in Green Agriculture" projects stood out from more than 4,900 teams across the country and won the "Most Investment Value Team TOP5" award. At present, Shandong Mingbang Environmental Protection Technology Co., Ltd. plans to invest in the project. "This fertilizer is recommended to use about 100-300 kilograms per acre of land. It is particularly suitable for the production of high-value-added economic crops. It is expected to replace traditional organic fertilizers. In the future, China's food security must increase the support of science and technology while increasing the number of "quality". Based on the specific conditions of each local soil and the types of crops, the proportional and personalized customization can be made. In order to produce more effective and high -quality crop production, this research and development cost and process are necessary. "

High -end product big stage

How to develop mid -to -high -end products and extend the industrial chain, how should bumps go on a larger stage? Liu Weisheng's team has mastered the secrets of victory after years of research and development!

It is necessary to make up for the market chain of the convex rod series, and mid -to -high -end products are indispensable, especially high -end high -end products with high value.

As far as the rubber additive market is concerned, in 2022, the global natural rubber consumption expenditure increased by 1.2%year -on -year to 14.232 million tons. The demand for rubber additives brought by it was also a considerable market. At present, the most ideal reinforcement material for rubber is still charcoal black, but its production process is complex, environmental pollution is large, and the price is high. Therefore, finding new cheap and environmentally friendly reinforcement materials has become a trend.

Due to the extensive sources of uneven rods, low prices, and no pollution, it is made into environmentally friendly rubber filling reinforcements through a certain channel, and preparing rubber/bumpbone composite materials is the development trend of the rubber material industry. By 2020, the demand for raised rods rubber additives has reached 3 million tons/year.

In recent years, there have been many research on rubber/bumps nano -composite materials, but most of them have problems such as uniform dispersal dispersion and tightly combined with the rod crystal and the rubber chain. No reporting of the industrialization of composite materials has been found. The application of nano -grade bumps in polymer materials can not only greatly improve the nuclear performance, mechanical properties, size stability, and anti -aging performance of composite materials, but also because of the quantum effects of nano -class bumps, it can also be given to given Some new features. However, due to the special structure of the bump and stone, it is a hydrophilic inorganic nanochable material material. It is very compatible with most surface polymer materials with most surfaces. Mixing nano composite materials through mechanical mixing.

The industrialization of the bumps/chores rubber

Test: Puerassing Blocking Live

After more than 10 years of technical exploration of Liu Weisheng's research group, Liu Weisheng uses self -developed modified bumps, and uses lotion to co -condense the method to prepare rubber/bumps. The problem. At the same time, it also studies its modified process, adding method, additive amount on the micro structure, thermal stability performance, mechanical performance, aging performance, solvents resistance, etc. of the rubber. Among them, 4 have been authorized.

With the strong support of Lanzhou Petrochemical Corporation, patented technology uses China Petroleum Lanzhou Petrochemical Company 15,000 tons of Tinto rubber production lines to conduct laboratory results for industrialized testing of bumps and bonding rubber nano -composite materials to achieve the laboratory in the laboratory Transformation of technology to industrial production. The test results show that the prepared new -diced rubber has good mechanical properties, and its performance has reached the excellent factory indicators of Tidan rubber, which is slightly better than the trunchen rubber imported from abroad; The process can be well controlled and meets the requirements of batch production; the product produced by the chipped rubber seal has excellent performance and meets product requirements. The project has now entered the stage of industrialization experiment. It is expected to be put into production in Zhejiang, and the global market prospects can reach billions of yuan.

Tactically transform the resource advantage into industrial advantages

What kind of industrial advantage does the new material of the bumps have achieved the layout of industry -university -research? What is the future development prospects? A sentence "Unexpected" gives the answer.

Gansu's layout of bumpbone production research has been carried out for nearly ten years. Liu Weisheng's work has always been an important part of it. The director of the Callout Mineral Resources Comprehensive Utilization Engineering Research Center "and other positions, the company's cooperative enterprises have emerged and successfully listed in the silver high -tech industrial park. Northwestern University of Technology, Guangdong University of Technology and other scientific research institutes.

In September 2018, based on the advantages of bumps, the Green Materials R & D Center of Lanzhou University was established. It mainly focuses on the research and product development of green materials, and vigorously develops new product transfer and transformation capabilities. At the same time, Lanzhou University faces Chongqing, Jiangsu, Shandong The construction of technical transfer centers such as Gansu and other provinces. "Development-China Test-Industrial Acceptance Production" is a three-step three steps that the uneven rod will take from laboratory to corporate workshops. Combining national policies, school systems and local actual situations, Liu Weisheng team has found technical transfer in more than ten years of exploration. Cooperation development and co -construction research platform resource sharing models.

Yilan Green Materials Industry Research Institute

With the help of Jiangsu's high -quality uneven sticks resources, the Xinyi Green Materials Industry Research Institute Co., Ltd., the Xinyi Green Materials Industry Research Institute Co., Ltd. It was officially established in December 2020, and the total investment in the first stage was about 5 million yuan.

In 2020, Lanzhou University will be "a modified method of a bumpy soil", "natural mineral uneven rods, and the yellow fluorescent powder SR3SIO5: M1, M2 (M1 = CE3+or EU2+, M2 = Li+or BA2+)" The type of transfer of price investment was successfully transferred to Yilan Green Material Industry Research Institute Co., Ltd. At this point, Jiangsu Xinyi City and Lanzhou University "echoed each other" to achieve remote resource sharing.

In February this year, the heads of state -owned enterprises dedicated to the development of the comprehensive industry of modern agriculture -the head of the China Rongtong Agricultural Development Group Corporation and the leaders of Baiyin City came to Lanzhou University to investigate and investigate, in order to further land the silver project for the turbulent rod project to be green China and Healthy China. He has made due contributions to the revitalization of the countryside.

The magical bumps have been clearly determined by the "Fourteenth Five -Year Plan for National Economic and Social Development in Gansu Province and the Outline of the 2013 Far -Year Vision Target". "Promoting the development of the new material industry in the northwestern region, the development needs of the production and consumption upgrade and the development of strategic emerging industries, and accelerating the promotion of the industrial green transformation is of great significance." This year's two sessions said.

Regarding the development, research and application of bump resources, Liu Weisheng believes that it can only reach 40-50%of the current level. Policy support, improve the speed of the application of scientific and technological achievements, continuously improve the entire industrial chain of the convex rodstone, and promote the industrialization of uneven rodstone. "

Recently, it was initiated by the Expert Station of Zhangye Zhangye, Gansu, and Liu Weisheng's participation in the Consultation and Evaluation Project of the Chinese Academy of Sciences "the current status and development recommendations for the use of bumpbone resources in my country" has also been completed. Different characteristics of the district and mineral belts formulate the development strategy of differentiated and misplaced development of the entire industry chain, maximize the use of resources to maximize the use of resources, and completely transform the resource advantages into technical advantages and economic advantages.
