PhosphatesIndex. décimale : 667.9 Revêtements et enduits Résumé : As professionals working within the coatings industry, we are all acutely aware of the issues that corrosion poses and want to provide our customers and end-users with the best quality products to tackle this $2.2 trillion global issue. Anticorrosion coatings have become a necessity for industries to safeguard the huge investments they make in terms of money, property and safety of workers. Whether coating to protect pipelines, aeroplanes or computer gadgets – customers are united in their battle against corrosion ! Historically, some of the most effective corrosion inhibitors have been based on chromium. However, these chemistries are currently being phased out globally – leaving a gap in the market for a highly effective inhibitor that is non-toxic and non-carcinogenic.
Following strong R&D efforts and extended testing, many coatings companies have turned to phosphate-based systems. This article highlights a step-change alternative that can save up to 30 % on the cost of anticorrosives as well as offering customers more sustainable coatings that require no hazard warning label.Note de contenu : - Why phosphates are popular

Titre : Coal-derived, solid resins as economic raw materials for coatings Type de document : texte imprimé Auteurs : Stefan Holberg, Auteur ; Xinyan Wang, Auteur ; William C. Schaffers, Auteur ; David A. Bell, Auteur ; Jeramie J. Adams, Auteur ; Patrick A. Johnson, Auteur Année de publication : 2021 Article en page(s) : p. 921-931 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

Test d'immersionIndex. décimale : 667.9 Revêtements et enduits Résumé : Solvent extraction of subbituminous coal at mild conditions (360°C) provides solid extracts that consist of numerous organic molecules that can be utilized in the synthesis of polymeric coatings. We describe the extraction process as well as the application of the resultant materials, which bear phenolic groups as the main reactive functionality, for the synthesis of polyurethane and epoxy coatings. The respective reactions of coal extract with isocyanates or epoxides were validated by 13C-NMR. By combining 50–67% coal extract with suitable, flexible co-reactants and co-resins, we formulated coatings with excellent wet adhesion to aluminum, flexibility, and corrosion protection with the same quality as reference coatings. The work is an advancement toward the goal of developing economic and resource-efficient routes from coal to polymers with attractive properties, where coal extracts can compete with petrochemically derived raw materials.

RevêtementsIndex. décimale : 667.9 Revêtements et enduits Résumé : In 2008, a project between the National Park Service and the Warrent Lasch Conservation Center (WLCC) of Clemson University Restoration Institute was initiated to develop a protocol for conservation treatment on a selected set of ordnance and metal architectural elements at South Carolina's Fort Sumter National Monument, to include Fort Moultrie.
One of the key purposes of this research, and a factor that sets this project apart in the field of conservation, is the ability to provide comparative testing of several removal methods as well as coating products on historic metal substrates. Preliminary testing on coupons and substrates with no historic provenance has been running alongside laboratory and on-site testing on actual historic artifacts throughout the complex chronology of the project.
The manner in which the project was designed from its inception, as a collaborative research effort, has made this work possible. Continuous, open, and effective communication between the different entities-Federal, State, and private-has been crucial in defining a goal and executing a plan that is achievable and sustainable, while contributing considerably to research and education within the multifaceted field of preservation and stewardship of cultural heritage.Note de contenu : - CONSERVATION AND ETHICS

Métaux -- Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : From its origin, the word “manhole” had nothing to do with sewers. The original use came from the days of sailing ships to denote access points between a ship’s decks. Later the term was used to describe sewer access points due to the similarity of providing access for a human to move from one level to another — in this case from street level to the sewers underneath for maintenance. In the United States alone, an estimated 20 million of these access points dot roadways, sidewalks, fields and other areas. Evaluating and estimating the service life of these structures has become of critical importance to the overall operation of sewer collection systems. Note de contenu : - Evaluating manhole maintenance systems
- Performing manhole maintenance - day one and two
- Verifying results via field inspection
- Lining it all up
- FIGURES : 1. For manholes facing more aggressive service environments, it is advisable to apply a protective lining material as a topcoat to mitigate the effects of corrosion on the restored surfaces - 2. Corrosive gases and liquids inside manhole structures cause concrete to break down and steel to corrode, potentially creating leaks and subjecting sanitary collection systems to unwanted water infiltration that further taxes the systems - 3. Spraying and hand-troweling a stand-alone calcium aluminate mortar has proven to be a sufficient long-term repair for manholes not subjected to significant corrosive attacks - 4. Manhole structures tend to deteriorate over time due to exposure to a variety of corrosive materialsEn ligne : http://www.paintsquare.com/archive/?fuseaction=view&articleid=5914 Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28392
