[China Instrument Network Instrument R&D] Recently, Zhejiang Metrology Institute developed a calibration system for scattered fly ash microwave quality metering devices for Hangzhou Environmental Protection Technology Co., Ltd., which solves the problem that the company's fly ash inventory cannot be measured online. The on-line measurement problem of solid waste pollution control and comprehensive utilization provides a reference model and provides measurement support for the development of green industry in Zhejiang Province.
Fly ash is a waste residue after waste incineration treatment. In recent years, fly ash has been widely used as an important blending material in cement production, but its online measurement and traceability is a problem.
After learning about the enterprise problems, the Institute of Mechanics at Zhejiang Institute of Surveying and Informatics sent technical experts to the on-site site survey and found that the company’s fly ash inventory metering device was over the ground above the ground, with multiple pipelines underneath, and the difficulty in measuring the silo size and installation position. . Technical experts repeatedly climbed up the overhead equipment layer and repeatedly viewed the pipeline layout, fly ash alignment, and space structure, innovatively designed a metering silo installed at the site, and developed a microwave based on powdered fly ash. The quality measurement device calibration system ensures the accurate and reliable online measurement of fly ash inventory and is well received by the company.

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.
