Titre : Adaptation of advanced coating in new generation fighter class aero-engines Type de document : texte imprimé Auteurs : Benudhar Sahoo, Auteur ; G. Gouda, Auteur ; R. Krishnan, Auteur Année de publication : 2002 Article en page(s) : p. 83-90 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : New generation fighter class aero-engines are dictated by the higher thrust requirement and lower specific fuel consumption, thereby increasing the turbine entry temperature and going towards higher strength to weight ratio materials for compressors. As there is a limit for the high temperature capability of the material, the same is improved by adopting different types of thermal barrier coatings. The major modes of failure of cold end components are high cycle fatigue and stress corrosion, while that for hot end components are low cycle fatigue, thermal fatigue and hot corrosion, etc. Various modes of failure of different components impose complex requirements on the designer for material selection. Apart from this, major failure like fatigue and corrosion starts from the surface. Because of the higher thrust and greater revolution of rotating components and the gyroscopic loads, there is considerable wear and tear and vibration during exploitation, increasing the premature withdrawals to an alarming situation. This paper deals with the various advanced coatings that are applied to the different components of a typical new generation fighter class aero engine for I) Design up-gradation, ii) Ease of maintenance, iii) Improving the reliability of operation.

Titre : Health and safety aspects of pigments Type de document : texte imprimé Auteurs : A. B. Karnik, Auteur Année de publication : 2002 Article en page(s) : p. 91-102 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Chemicals are subject to a growing number of regulations pertaining to their industrial operations such as the transport of goods and consumer usage. Many of the regulations applicable to pigment dry colors are based not on the pigments per se, but on heavy metals or other inorganic components used in their manufacture.
Pigments serve many beneficial functions in modern society and technology. Irrespective of their end use, they are not considered consumer chemicals, but are primarily directed to a variety of industries. They are processed into products such as paints, printing inks and platics, which are then directed to other industries and then on to their respective consumer markets.
Industry has the responsibility to be informed ot the potential hazards associated with the raw materials, so that suitable measures may be taken to insure the safety of employees, customers, the public, and the environment. In this article, safety and health information for pigments is discussed briefly.
It is presumed that the pigment is a dry powder without surface treatment. No attention has been paid to the risk potential of vehicles, solvents, and other materials used in the preparation of various pigment grades. With appropriate handling procedures, engineering controls and personal hyigienic practices, no pigment any grade should pose a health risk to the industrial worker.
Under normal circumstances, pigment dry colors are nonflammable and unreactive chemicals. It is important, however, to appreciate that there are certain abnormal circumstances associated with the storage and/or use of pigment products, under which hazardous situations may occur. There are three such circumstances : excessiveheat, dust explosion, and chemical reactivity.Note de contenu : REGULATIONS : OSHA Standard 29 CFR1910:1000 - EEC labeling directive - Additional regulatory concerns - CPSC ban on lead - ANSI Z66.1 Standards Institute (ANSI) - Excessive heat - Dust explosion

Titre : New resin development for future green paints Type de document : texte imprimé Auteurs : Jaap Akkerman, Auteur ; R. Hall, Auteur ; P. Vandevoorde, Auteur ; Dirk Mestach, Auteur Année de publication : 2002 Article en page(s) : p. 131-144 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : In this paper an overview is given of the recent developments of our new resin technologies for environmentally friendly green paints such as 2 component high solids cured with isocyanate - (HS 2C), 2 component waterborne cured with isocyanate - (WB 2C NCO), 2 component waterborne cured with non isocyanate - (WB 2C AA), waterborne self crosslinkable acrylic dispersions - (WB 1C) and waterborne basecoat resins - (WB BC). The presentation highlights the research approach of the technology, the application in paint and the experiences in the marketplace. The solutions as presented here, are not brand new technologies, but more second or even third generations that were developed during experiences in the market over the last five years. Small alterations in our resin technology, often meant significant improvements in the paint application. Also can be seen that green solutions differ not only per market segment (e.g. refinishes versus plastic coatings) but also per country or even region and customer. This means that the resin company has to supply a range of solutions for green paints.

Titre : Hybrid polymer sealants-minerals for performance enhancement Type de document : texte imprimé Auteurs : D. Preston, Auteur ; Erik van Dijnen, Auteur Année de publication : 2002 Article en page(s) : p. 145-150 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Sealants based on hybrid polymers such as silyl-terminated polyethers combine good weathering characteristics, paintability and stain resistance, and excellent adhesion to a wide range of substrates. In silyl-terminated polyether sealants the mineral component can represent over 50% of the mass of the sealant. The choice of mineral will therefore have an impact on the processing and ultimate performance of the sealant. This paper evaluates the performance of minerals in such sealants. Specifically, the effects of coated ground calcium carbonates on sealant stability, rheology and curing and hardened tensile properties are reported. The potential impacts on the sealant process routes are discussed in parallel. The results demonstrate that sealant production processes can be simplified and sealant properties improved through selection and control of the physical properties of the mineral component.

Titre : Role and function of rheological additives in modern emulsion paints and industrial coatings Type de document : texte imprimé Auteurs : P. Manshausen, Auteur Année de publication : 2002 Article en page(s) : p. 151-162 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Thickening additives have a major infulence on the storage stability and processing properties of liquids systems. They have always been an important component in the formulation of sovant-based coatings. Back at the coating formulation stage, they help to optimise energy introduced in the milling phase, thus enhancing dispersibility. At the same time, they improve storage stability by reducing the sedimentation tendency and syneresis. In the industrial application of such systems, they imrove leveling and reduce yhe sagging tendency of the coatings.
With the increasing demand for low-VOC or VOC-free water-borne coating systems, there has been a call for a new class of thickeners - known as modern rheological aditives. These additives allow specific modification of the viscosity of the system at various shear rates. As a result, such key coating properties as vertical flow, leveling, gloss, film thickness, covering power, spattering tendency, brush and roll resistance, sedimentation tendency and pigment stabalization - to mention only some of the most important - are significantly affected.In most cases, only small quantities of between of 0.1 and 4%, calculated on the formulation, are enough to obtain ideal flow properties for a particular application. In addition, such additives also make recommendations on the choice of suitable systems with the aid of a few selected examples.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12296
