Cracked coating and lifted edges on the metal panel wall - 3. Tape adhesion tests performed on the ceiling produced mixed results even in the same vicinity (note thickness values written on surface) - 4. When tapping produced a "hollow" sound, the epoxy ester film was delaminated although appearing visibly intact - 5.

Hazardous metals and materials / Alison B. Kaelin in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 34, N° 10 (10/2017)

All of us, from the office to the field, might need a few reminders about these tasks. Note de contenu : - NOT ALL TESTING IS CREATED EQUAL - WHAT IS IN THE EXISTING COATING ? : The first reason - The Second Reason - WHAT IS IN THE MATERIALS ? - WHAT WASTE STREAMS WILL BE GENERATED AND ARE THEY HAZARDOUS ? : Ignitability - Corrosivity - Reactivity - Toxicity - SOLVENT-CONTAMINATED WIPES Table : Applicable OSHA Regulations and Waste Stream Constituents En ligne : http://www.paintsquare.com/archive/?fuseaction=view&articleid=6150 Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29506 [article]

Troubled bridge over salt water / Michael O. Woodward in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 34, N° 10 (10/2017)  

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 34, N° 10 (10/2017) . - p. 22-27 Titre : Troubled bridge over salt water Type de document : texte imprimé Auteurs : Michael O. Woodward, Auteur Année de publication : 2017 Article en page(s) : p. 22-27 Langues : Américain (ame) Catégories : Délaminage Epoxydes Ponts -- entretien et réparations Ponts métalliques -- Revêtements protecteurs Revêtements -- Entretien et réparations:Peinture -- Entretien et réparations Index. décimale : 667.9 Revêtements et enduits Résumé : The Miami Avenue Bridge consists of a pair of 629-foot bascule bridges that sit in the heart of downtown Miami’s Brickell City Center. It is surrounded by high-rise buildings and crosses over the Miami River, a heavily utilized waterway for recreational crafts, cargo vessels and private yachts traveling to and from the Atlantic Ocean. The existing coatings on the bridge spans were experiencing catastrophic intercoat delamination failure between the intermediate coat and the inorganic zinc-rich primer. The primer was tested by an independent third-party inspection firm. They determined it had sufficient adhesion values and life-cycle remaining, making it a strong candidate for an overcoat system in lieu of a full blast requirement. Furthermore, officials involved with the project wanted to limit the amount of downtime required to take the bridge out of service in order to perform the scheduled repairs — expediting the revitalization of the coatings by minimizing the surface preparation requirements as much as possible without compromising the integrity and performance value of the applied system. Note de contenu : - Coating selection - Projet implementation FIGURES : 1. The topside of the bridge span showing the existing coating failure - 2. The underside of the bridge span showing the existing coating failure - 3. Cross-linked polymeric epoxy intermediate coat application - 4. North spans completed; south side preparations beginning - 5. New galvanized grating being installed over completed spans - 6. QA/QC — dry-film thickness-testing reading taking place - 7. Finished application of the coating system TABLE : Dry-film thickness and adhesion tests En ligne : http://www.paintsquare.com/archive/?fuseaction=view&articleid=6145 Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29507 [article]

Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).
