Revêtements antisalissures:Peinture antisalissuresIndex. décimale : 667.9 Revêtements et enduits Résumé : In a double benefit for the global economy and world climate, Evonik plans to make ship hulls invisible to micro-organisms and so to protect them against biofilms, algae, and bivalves. Growths of this kind, referred to as biofouling, push up fuel consumption in shipping and, thus also CO2 emissions on the world's oceans.
The International Maritime Organization estimates that the annual costs caused by biofouling lie in the billion-dollar range. Evonik is working on a solution to the problem in the form of 3 new eco-friendly coating that counteracts biofouling. The coating tricks micro-organisms into perceiving plain water in front of them, rather than the ship's hull ; as a result they often make no attempt to settle on the hull.
Biofouling has long been a problem for shipping companies the world over : organisms settle on the ship's walls, changing the smooth surfaces into a rough and ragged shell. This increases frictional resistance in the water, so that biofouling slows down ships. These thon need more energy to maintain their speed, which is bad news for bath fuel costs and the environment. Marine transport accounts far about 90% of global freight forwarding.Note de contenu : - One of the last unsolved problems in the industry

Salissures marines
SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. 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).Index. décimale : 667.9 Revêtements et enduits Résumé : Siloxane-polyurethane paints were formulated and characterized for coating properties and performance as fouling-release (FR) marine coatings. Paints were formulated at 20 and 30 pigment volume concentrations with titanium dioxide, and aminopropyl-terminated poly (dimethylsiloxane) (APT-PDMS) loadings were varied from 0 to 30% based on binder mass. The coatings were characterized for water contact angle, surface energy (SE), gloss, and pseudo-barnacle (PB) adhesion. The assessment of the FR performance compared with polyurethane (PU) and silicone standards through the use of laboratory biological assays was also performed. Biofilm retention and adhesion were conducted with the marine bacterium Cellulophaga lytica, and the microalgae diatom Navicula incerta. Live adult barnacle reattachment using Amphibalanus amphitrite was also performed. The pigmented coatings were found to have properties and FR performance similar to those prepared without pigment. However, a higher loading of PDMS was required, in some cases, to obtain the same properties as coatings prepared without pigment. These coatings rely on a self-stratification mechanism to bring the PDMS to the coating surface. The slight reduction in water contact angle (WCA) and increase in pseudobarnacle release force with pigmentation suggests that pigmentation slowed or interfered with the self-stratification mechanism. However, increasing the PDMS loading is an apparent method for overcoming this issue, allowing for coatings having similar properties as those of clear coatings and FR performance similar to those of silicone standard coatings.

Structures offshore -- Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : A cryogenic spill can be similar to a hydrocarbon fire in terms of thermal shock. It is, therefore, essential that intumescent epoxy coatings must protect from extreme cold, as well as fire.
Traditionally, flexible epoxy passive fire protection, PFP, coatings have been used in environments where exterior or durability and corrosion resistance are required. The difference in these coatings to standard paints is that they are applied at much higher film thicknesses and, as such, they can be used without the need for active methods of protection such as the activation of a sprinkler system.
Many companies working in offshore oil and gas exploration are aware of the importance of using fire-protective coatings on their fixed and floating assets and will typically select a coatings system that will function in a specific operational environment, eg, where loading, storing or unloading cryogenically-cooled liquids, remains a challenging process.En ligne : https://drive.google.com/file/d/1dMCuu7RVJUHKSuEclBKhGUplxovDpxPO/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=20748
