This book was released on 1985 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid rocket motor performance is greatly influenced by the size of various solid ingredients such as that of the oxidizer or metal fuel. The particle size instrument of choice with the solid propellant industry in the past has been the Mine Safety Appliances Co. (MSA) particle size analyzer. The MSA measures equivalent stokes diameters by a combination of gravity and centrifugation. Unfortunately, this instrument is no longer commercially available, thus an urgent requirement exists in the solid propellant industry to find an alternative particle size instrument that will provide statistically similar results to the MSA. The HIAC Royco, PA-720, has been found by this laboratory to be a reliable particle size instrument. A direct comparison of the particle size distributions obtained by the MSA and the HIAC Royco instruments is presented. A microcomputer program was also developed for calculating various statistical means from the raw data of both instruments to aid in the representation of a particle size distribution. The data indicates that the HIAC Royco particle size distributions are more nearly log normal and more biased toward the coarse particles than the MSA data.

Available in PDF, EPUB and Kindle. Book excerpt: Powder technology is a subject in its own right, and powder characterization is central to an understanding of this discipline. In the eight years since the printing of the third edition of Particle Size Measurement there have been two big changes in my life. After thirty years of academia I have returned to industry, and after a lifetime in Great Britain I have emigrated to the United States. In industry the initial demand is to relate powder properties to product performance and then to maintain powder consistency. This requires on-line or rapid off-line analysis which, in turn, has led to the demand for a whole range of new instruments whose primary function is process monitoring. Historically, chemical engineering courses have concentrated on the be haviour of fluids, and engineers enter industry relatively unschooled in the subject of powder behaviour . Yet, when my colleagues Reg Davies and John Boughton surveyed three thousand Dupont products, they discovered that 80% involved powder at some stage of their manufacture. The results of this survey illustrate the need for more training in this key subject. This edition reflects the changing image of powder characterization towards in-process size analysis. Hence the chapter covering on-line analysis has been largely re-written. Apart from this, I have expanded certain sections and describe the new instruments that have been introduced since the last edition.
Download or read book Particle Size Analysis written by N G Stanley-Wood and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle Size Analysis reviews the development of particle characterization over the past 25 years and also speculates on its future. Interest in the subject has increased enormously over the years and this book highlights the changes and advances made within the field. This book is comprehensive in its coverage of particle size analysis and includes contributions on such characterization techniques as microscopy using fractal analysis, light diffraction, light scattering with the phase doppler technique, light observation, and photon correlation spectroscopy. A number of chapters address the interest in on-line in-stream particle size analysis and illustrate the progress being made in achieving this long sought after ideal of in-situ in-process particle characterization. Applications to other technological fields are detailed by chapters covering biological systems and the pharmaceutical industry. The subject of surface area determination is considered with particular emphasis on the measurements on porosity of powders, the characterization and comparability of reference materials, and the need for standards. Particle Size Analysis should provide stimulating reading for technologists, scientists, and engineers involved in particle characterization and powder technology worldwide.

Download or read book Particle Size Measurements written by Henk G. Merkus and published by Springer Science & Business Media. This book was released on 2009-01-07 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the practical aspects of particle size measurement: a major difference with existing books, which have a more theoretical approach. Of course, the emphasis still lies on the measurement techniques. For optimum application, their theoretical background is accompanied by quantitative quality aspects, limitations and problem identification. In addition the book covers the phenomena of sampling and dispersion of powders, either of which may be dominant in the overall analysis error. Moreover, there are chapters on the general aspects of quality for particle size analysis, quality management, reference materials and written standards, in- and on-line measurement, definitions and multilingual terminology, and on the statistics required for adequate interpretation of results. Importantly, a relation is made to product performance, both during processing as well as in final application. In view of its set-up, this book is well suited to support particle size measurement courses.

Download or read book Particle Size Measurement written by Terence Allen and published by Springer. This book was released on 1996-12-31 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the fifth edition of the highly successful work first published in 1968, comprising two definitive volumes on particle characterisation. The first volume is devoted to sampling and particle size measurement, while surface area and pore size determination are reviewed in volume 2. Particle size and characterisation are central to understanding powder properties and behaviour. This book describes numerous potential measuring devices, how they operate and their advantages and disadvantages. It comprise a fully comprehensive treatise on the wide range of available equipment with an extensive literature survey, and a list of manufacturers and suppliers. The author's blend of academic and industrial experience results in a readable technical book with information on how to analyse, present, and extract useful information from data. This is an essential reference book for both industrial and academic research workers in a variety of areas including: pharmaceuticals, food science, pollution analysis and control, electronic materials, agricultural products, polymers, pigments and chemicals.
