This paper demonstrates the necessity and background of the development of dynamic particle image analyzer, and introduces the method and technical characteristics of the dynamic particle testing of winner100. The practical value and scientific significance of the dynamic particle image analyzer were evaluated.
Keywords: Dynamic Particles, Image Analysis, Particle Size and Shape, 3D I. Problem Proposing Particles are the basic units of the constituent materials, and not only the chemical composition of the particles, but also the size of the particles and the morphology of the particles. The impact of the performance is huge, so the detection of particle size and morphology has received increasing attention from various industries. At present, there are many methods for measuring particle size and particle morphology. Laser particle size analyzer, sedimentation particle size analyzer, resistance particle size, and particle image analysis technology are the most commonly used techniques. The laser particle size analyzer, sedimentation particle size analyzer, and resistance particle size analyzer can only detect particle size and cannot detect particle shape; particle image analysis technology is the only method that can not only detect particle size but also can detect particle shape, but due to this Several fatal flaws in technology have limited its further development:
1. Sample preparation is difficult. Particles are difficult to fully disperse on glass slides, and the accuracy of particle analysis is greatly affected by particle adhesion.
2. The particles are static, and the orientation of non-spherical particles will deviate from the test results;
3. Due to the limited field of view of the microscope, the number of particles to be measured is very limited, so the representativeness of the samples is poor and the repeatability is not good.
Due to the above problems, there is an urgent need for a test device with superior performance in particle testing, which can obtain accurate images of particles and is easy to operate, meeting the higher requirements of particle shape and particle size analysis.
Internationally, the Netherlands-based AMD, Germany's Newpactech, and Germany's Ritchie have introduced image analyzers that simultaneously measure particle size and shape. There is no such product in China. Jinan Micron Corporation has filled this blank through the winner100 particle image analyzer developed in the past three years.
Second, dynamic particle testing methods and technical characteristics Winner100 breaks through the traditional particle imager working mode, using ultrasonic sample dispersion system to disperse particles, high-speed camera to collect dynamic particle images, 1 microsecond can collect a particle image, with The computer analyzes and processes the image to achieve the three-dimensional simultaneous testing of particle size and morphology. Its main technical features are:
1. Thoroughly changed the situation where the manual sample preparation was cumbersome, the sample preparation operation was very simple, and the dispersion effect was good;
2. Using powerful dynamic particle image analysis software, with high-speed sampling, automatic particle image processing, real-time display of the current image, real-time analysis of particle size distribution, continuous statistical analysis results, processing strategy self-programming, a variety of particle size definition selection, particle size statistics , shape analysis and other functions. Print reports allow self-editing.
3. The dynamic test makes the number of particle samples increase indefinitely, and the statistical results are true and reliable, with good representation and high repeatability.
4. The dynamic test has sampled the different sides of the particles, achieved a three-dimensional test, completely eliminated the two-dimensional test particle orientation error; particle size test results can be compared with the laser particle size analyzer.
5.Winner100 special software for dynamic image analysis has powerful image processing functions;
6. Support a variety of particle size selection and a variety of particle size distribution, with a variety of image processing functions and its integrated processing, support image acquisition interval setting and real-time display of particle morphology and particle size distribution and cumulative particle size distribution, record and display granularity Wave charts can output a variety of analysis charts. High-performance software makes it easy for users to perform particle analysis.
7. This result can be used not only for laboratory particle analysis, but also for on-line particle size and particle shape monitoring.
The significance of the economic development and scientific progress of Duhui The project breaks through the limitations of microscopic static image analysis. It first proposed the concept of dynamic particle image analysis in China; because of particle motion testing, it overcomes the disadvantages of two-dimensional particle image analysis. The sampling representative is improved, the particle orientation error is eliminated, and the particle adhesion problem is completely solved.
This achievement overcomes the defects of the static particle imager and provides an advanced method for simultaneously analyzing the particle size and shape of the moving particle. It has the advantages of simple operation, wide test range, good representation, accurate and reliable, and intuitive and applicable. 1-6000 microns of various solid particles. It can be widely used in laboratory and online particle size and shape analysis of building materials, chemicals, petroleum, metals and nonmetals, environmental protection, light industry, national defense and many other fields. Undoubtedly, it has important practical value for improving the level of particle testing and economic development in various industries in China.
The basis of particle testing is particle characterization. This result provides a practical means for particle dynamic testing. Therefore, the three-dimensional representation of particles is mentioned on the agenda. The three-dimensional representation of particles is important for the progress and development of granules. significance.
Particle shape analysis has mostly stayed in the laboratory before and has not been put into practical use because of the lack of simple testing methods. The successful development of Winner100 may lead to the analysis of particle shape into a practical stage, thus providing an advanced and practical instrument for the development of materials science, especially granular materials.
