X-ray photochromic material performance optimization and functional development studies acceptance

China Instrument Network Instrument Research and Development On December 21st, Fujian Provincial Institute of Natural Science and Technology, Wang Mingsheng, chaired by the Fujian Province Natural Science Foundation, the “X-ray Photochromic Material Performance Optimization and Functional Development” project was organized by the Science and Technology Department of Fujian Province. Expert acceptance.

The project team used the combination strategy of forming clusters of high atomic number atoms, shortening the distance between electrons and acceptors, and increasing the electron acceptor's ability to acquire electrons in response to the problems of existing discolored materials such as slow response time to X-rays (especially hard X-rays). X-ray photochromic materials with X-ray response time less than 5 minutes were obtained; by introducing a discoloration competition mechanism, the first material with energy-dependent X-ray photochromic behavior was obtained, providing a simple way to qualitatively distinguish X-ray energy. Methods: The idea of ​​inlaying color-changing elements between lead halide layers was proposed, and the first material that can both block X-rays and change the X-ray response was obtained, providing a functional alternative to lead glass.
During the project implementation, 11 SCI papers were published (6 papers in the first and second class journals of chemistry disciplines) and 1 invention patent was authorized; project leaders were awarded “top-notch young scientists” and “excellent members of the Qinghui Society” by the Chinese Academy of Sciences. title.
The establishment of the Fujian Outstanding Young Scientists Fund project identified and trained a number of outstanding young academic and industry technology leaders in Fujian, and promoted the research and development of science and technology in related disciplines. Since 2009, a total of 17 researchers from Fujian Institute of Materials have received funding from the Provincial Natural Science Foundation Jieqing project, of which two have received rolling support.

The final product will be 40%-45% tire oil (fuel oil), carbon black and 35% carbon black, 10% steel and another 5-10% recycled gas (CH4-C4H10).

 

The main process is to pyrolyze the tire into oil and gas by directly heating the reactor;

The condenser or cooling tube will cool the gas to a liquid oil with the aid of circulating water;

Then, the remaining gas that cannot be cooled into liquid oil is recycled to the reactor heating system; after the oil and gas is completely discharged, the reactor is stopped to be cooled, and the reactor below 70 degrees is cooled; then the door can be automatically opened and the carbon black can be discharged. .

The capacity of each batch of products ranges from 5 tons to 20 tons.

LN-2200-6000 capacity 5-6 tons

LN-2200-6600 has a capacity of 7-8 tons

LN-2200-8000 has a capacity of 9-10ton

LN-2600-6600 has a capacity of 10-12ton

LN-2600-8000 has a capacity of 12-14ton

LN-2800-6000 capacity is 10-12ton

LN-2800-6600 has a capacity of 12-14 tons

LN-2800-8000 capacity is 15-20ton

If cut into small pieces, it can handle more.
