Download or read book The Application of Sensors for In Situ Measurements of In Service Grease Rheology written by Rich Wurzbach and published by . This book was released on 2013 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The in-service application of greases requires a careful consideration of the viscometrics of the fluid. Often this property is measured by the consistency of the grease using a cone penetrometer. This technique presents challenges related both to sample size and the suitability of this test for evaluating in-service grease performance. This paper describes the application of an on-line sensor designed for the measurement of lube oil viscosity to study grease fluid properties. Utilizing this in situ tool, the temperature effects of the apparent viscosity of the grease were studied. The temperature effects were evaluated in both static and dynamic environments. The study initially varied the temperature of the grease into which the sensor was immersed, and then progressed to placing the measurement tool into an operating environment to observe the dynamic response and viscometric changes of in-service operation. The non-Newtonian behavior of the grease provided a non-typical temperature-viscosity relationship. The conditions of dynamic flow also provided a measureable sensor response to give insight into flow mechanics and sensor placement for future measurements.

Available in PDF, EPUB and Kindle. Book excerpt: Lubricating Grease (Or Grease, To Use A Short Name), Leaving Aside Synthetic Grease For The Moment, Is Arguably Amongst The Highest Value Added Petroleum Products. Lubricating Greases Play Very Crucial Role In The Performance Of Automobiles, Industrial Machinery And Appliances Which Almost Every One Of Us Use, Rely Upon Or Work With Everyday. Lubricating Greases Account For About 5% Of The Global Consumption Of The Lubricants, Which In Turn Account For About 1% Of All Petroleum Products. Thus, In Volume Terms, Lubricating Greases Constitute A Relatively Small, Specialized Industry. Nonetheless, The Importance Of Lubricating Greases Can Not Be Overemphasized. The World Would Quite Literally Grind To A Halt Without Lubricating Greases.There Are Not Many Books On Lubricating Greases. Even The Very Few Books That Are Available In English Language, Largely Encapsulate The Work And Knowledge Developed In North America And West Europe. Significant Scientific And Technological Advancements Were Achieved In The Erstwhile East Bloc Countries During The Second Half Of The 20Th Century. However, It Is Only Over The Last Two Decades That Those Outside The Erstwhile East Bloc Have Been Getting Glimpses Of The Prolific Work Done By Scientists And Technologists In That Part Of The World. This Book Endeavours To Further This Process In A Small Way.

Download or read book Aqueous Lubrication Natural And Biomimetic Approaches written by Nicholas D Spencer and published by World Scientific. This book was released on 2014-03-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Man lubricates mostly with oil. Nature lubricates exclusively with water. Pure water is a poor lubricant, but the addition of proteins, especially glycoproteins, can modify surfaces to make them far more lubricating at slow speeds. Understanding how nature does this, and the physical structures involved, is not only important for the understanding of diseases such as osteoarthritis, but also essential for the successful application of articulating implants, such as hips and knees, as well as the development of medical devices such as catheters and contact lenses. A host of important applications of water-based lubrication are already in place in the personal care and food industries, and further industrial applications of water-based lubrication could have a significant positive impact on the environment.This book is the first of its kind. It brings together the latest research in biological and biomimetic, water-based lubrication and is authored by the world's experts in the field.

Download or read book Silane Coupling Agents written by Edwin P. Plueddemann and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: * It has been rumored that a bumble bee has such aerodynamic deficiencies that it should be incapable of flight. Fiberglass-reinforced polymer com posites, similarly, have two (apparently) insurmountable obstacles to per formance: 1) Water can hydrolyze any conceivable bond between organic and inorganic phase, and 2) Stresses across the interface during temperature cycling (resulting from a mismatch in thermal expansion coefficients) may exceed the strength of one of the phases. Organofunctional silanes are hybrid organic-inorganic compounds that are used as coupling agents across the organic-inorganic interface to help overcome these two obstacles to composite performance. One of their functions is to use the hydrolytic action of water under equilibrium condi tions to relieve thermally induced stresses across the interface. If equilib rium conditions can be maintained, the two problems act to cancel each other out. Coupling agents are defined primarily as materials that improve the practical adhesive bond of polymer to mineral. This may involve an increase in true adhesion, but it may also involve improved wetting, rheology, and other handling properties. The coupling agent may also modify the inter phase region to strengthen the organic and inorganic boundary layers.
Download or read book Chemistry and Technology of Lubricants written by Roy M. Mortier and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of lubricants began in ancient times and has developed into a major international business through the need to lubricate machines of increasing complexity. The impetus for lubricant development has arisen from need, so lubricating practice has preceded an understanding of the scientific principles. This is not surprising as the scientific basis of the technology is, by nature, highly complex and interdisciplinary. However, we believe that the understanding of lubricant phenomena will continue to be developed at a molecular level to meet future challenges. These challenges will include the control of emissions from internal combustion engines, the reduction of friction and wear in and continuing improvements to lubricant performance and machinery, life-time. More recently, there has been an increased understanding of the chemical aspects of lubrication, which has complemented the knowledge and understanding gained through studies dealing with physics and engineering. This book aims to bring together this chemical information and present it in a practical way. It is written by chemists who are authorities in the various specialisations within the lubricating industry, and is intended to be of interest to chemists who may already be working in the lubricating industry or in academia, and who are seeking a chemist's view of lubrication. It will also be of benefit to engineers and technologists familiar with the industry who require a more fundamental understanding of lubricants.

Download or read book Surface Application of Paper Chemicals written by J. Brander and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the exception of a slight hiccup during the height of the recent environmental movement (during the early 1990s), when for a year or two consumers were prepared to pay a price premium for lower quality recycled paper than for the virgin product, the inexorable improvement in the quality demanded of paper products continues. This demand for quality covers not only the aesthetics ofthe product but also its performance. Moreover, it is becoming increasingly the case that papers designed for a particular use must, as it were incidentally, also perform well in alternative applications. An example is that of office and printing papers, which are expected to perform as well in copier machines as in all the various forms of impact and non-impact printers. But even greater demands are made in other product areas, where board designed for dry foods can also be expected to protect moist and fatty materials and be made of 100% recycled fibre. The need to isolate foodstuffs from some of the contaminants that can affect recycled board is a· serious challenge. Thus, papermakers are constantly striving to meet a broadening spectrum of demands on their products; often while accepting declining quality of raw materials. The product design philosophy that has arisen in response to this is increasingly to isolate the bulk of a paper from its uses: to engineer the needed performance characteristics into the paper surfaces while more or less ignoring what happens inside.

Download or read book Acoustic Emission Testing written by Christian U. Grosse and published by Springer Science & Business Media. This book was released on 2008-07-12 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic Emission (AE) techniques have been studied in civil engineering for a long time. The techniques are recently going to be more and more applied to practical applications and to be standardized in the codes. This is because the increase of aging structures and disastrous damages due to recent earthquakes urgently demand for maintenance and retrofit of civil structures in service for example. It results in the need for the development of advanced and effective inspection techniques. Thus, AE techniques draw a great attention to diagnostic applications and in material testing. The book covers all levels from the description of AE basics for AE beginners (level of a student) to sophisticated AE algorithms and applications to real large-scale structures as well as the observation of the cracking process in laboratory specimen to study fracture processes.
