Revêtement monocomposant
Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : In last month's issue of ECJ a new concept called "thermoguard" was featured that could present enormous operational and economic gains for businesses when chiller condenser coils are protected against corrosion. Many industries such as mining, breweries, fertiliser plants, food processing operations and refineries, paper mills and petrochemical plants could dramatically reduce the rapid and costly energy loss caused by degrading heat exchanger units or uncoated coils in areas where both humidity and pollution cause rapid corrosion. Polyurethane coatings' specialists Eputan and Huntsman Polyurethanes present this new MDI - based coating for the heat exchanger market and explain the process behind its development. Note de contenu : - The pressure drop and heat conductivity parameters determline the performance of the coil
- The protective coating : chemical and abrasive resistant, flexible, UV and heat resistant
- Heat conducting coating solution
- Easy to handle and to apply
- Necessity to find the right functionality balanceEn ligne : https://drive.google.com/file/d/1MC__vPJ5xWDlwRh8ByHrgpmxRfPfjf8h/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10866

Taille des billesIndex. décimale : 667.9 Revêtements et enduits Résumé : Although most energy in inks and coatings manufacture is consumed in the fine grinding process, pre-dispersing is the area where it is possible to make the most significant efficiency and sustainability gains. Replacing high-speed dissolver technology with bead milling in the pre-dispersing stage can reduce the bead size required in fine grinding, reducing overall energy demand by as much 50 %, and cutting process times and costs.

PolysaccharidesLes polysaccharides (parfois appelés glycanes, polyosides, polyholosides ou glucides complexes) sont des polymères constitués de plusieurs oses liés entre eux par des liaisons osidiques.
Les polyosides les plus répandus du règne végétal sont la cellulose et l’amidon, tous deux polymères du glucose.
De nombreux exopolysaccharides (métabolites excrétés par des microbes, champignons, vers (mucus) du ver de terre) jouent un rôle majeur - à échelle moléculaire - dans la formation, qualité et conservation des sols, de l'humus, des agrégats formant les sols et de divers composés "argile-exopolysaccharide" et composites "organo-minéraux"(ex : xanthane, dextrane, le rhamsane, succinoglycanes...).
De nombreux polyosides sont utilisés comme des additifs alimentaires sous forme de fibre (inuline) ou de gomme naturelle.
Ce sont des polymères formés d'un certain nombre d'oses (ou monosaccharides) ayant pour formule générale : -[Cx(H2O)y)]n- (où y est généralement x - 1). On distingue deux catégories de polysaccharides : Les homopolysaccharides (ou homoglycanes) constitués du même monosaccharide : fructanes, glucanes, galactanes, mannanes ; les hétéropolysaccharides (ou hétéroglycanes) formés de différents monosaccharides : hémicelluloses.
Les constituants participant à la construction des polysaccharides peuvent être très divers : hexoses, pentoses, anhydrohexoses, éthers d'oses et esters sulfuriques.
Selon l'architecture de leur chaîne, les polysaccharides peuvent être : linéaires : cellulose ; ramifiés : gomme arabique, amylopectine, dextrane, hémicellulose et mixtes : amidon.

RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : Advances in the performance of formulated products through material innovation continue to drive innovation and growth. At the same time, it is becoming increasingly paramount that new materials are also sourced from ideally renewable and overall more sustainable feedstocks using benign processes to meet criteria required within a circular economy context.
Progress in architectural and industrial coatings has focused on providing not only improved paint performance but also optimizing aspects such as pigment efficiency (e.g., reduction of TiO2) and effective gloss management, while maintaining key characteristics such as abrasion performance and overall coating properties. At the same time, continued emphasis has been placed on reducing the environmental footprint through lower volatile organic content (VOC) in paint systems. In addition, increasing efforts have been directed to eventually replace typical petroleum-derived building blocks in coatings formulations with more sustainable, potentially renewable material alternatives.
However, the transition to performance-advantaged renewable building blocks, which are accessible at an enabling cost position and are also based on fungible, readily available raw materials produced in a sustainable and scalable industrial process, remains challenging across material industries. This article discusses one specific example of renewable based additive technology to meet the stated industry performance needs and objectives.Note de contenu : - ENGINEERED POLYSACCHARIDE FUNDAMENTAL MATERIAL PROPERTIES

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Montmorillonite (Mnt) and organic polymer composite membrane are widely used to enhance the corrosive resistance of metal materials due to their unique properties. Herein, a uniform anticorrosion membrane coated on aluminum plate was fabricated with organic-modified nano-Mnt (OMnt) and epoxy resin (EP) as raw materials, which showed good smoothness, wear property and resistance to acidic and salty corrosion. The surface morphology, crystal phase, chemical composition, and microstructure of the OMnt/EP membrane were characterized by optical microscopy, small-angle X-ray diffraction, FTIR, SEM, and TEM, respectively. The results showed that the OMnt/EP membrane was constituted of OMnt and EP. The interplanar distance of OMnt was expanded from 1.44 to 5.36 nm. Electrochemical corrosive resistance of the membrane was tested with Tafel polarization curves and electrochemical impedance spectroscopy. The results showed that the thickness of the membrane had a positive effect on its anticorrosion performance. When its thickness was 0.18 mm, its corrosion voltage (Pcorr) increased along with its content of OMnt, while its corrosion current (Icorr) showed increasing, decreasing and increasing trend as the content increased from 1 to 5%, from 5 to 7% and from 7 to 9%, respectively. When its content of OMnt was the same, its Pcorr increased along with its thickness, while its Icorr decreased along with its thickness. Its maximum impedance reached 2.29 × 107 Ω, which was much greater than that of other EP membranes. Moreover, the corrosion resistance of the composite membranes decreased gradually as the immersion time increased, and the content of OMnt and the ratio of EP to OMnt could also affect the corrosion resistance of the membrane. These results show that the OMnt/EP composite membrane exhibits excellent anticorrosive property, which is highly promising for wide applications in industry.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Polyetheramine (D230), an epoxy curing agent, was grafted on graphene oxide (GO) surfaces, which can be stably dispersed in a waterborne curing agent for more than 8 months. Waterborne epoxy coatings reinforced by D230-functionalized GO (DGO) were prepared on carbon steel surfaces. According to the electrochemical impedance spectra, the impedance modulus at 0.1 Hz remained at 2.2 × 109 Ω after 150 days of immersion in 3.5% NaCl electrolytes for 0.2 wt% DGO-reinforced waterborne epoxy coatings, while that of the neat epoxy coatings dropped below 1 × 107 Ω after 10 days. Besides, the addition of DGO enhanced the weathering resistance of waterborne epoxy coatings. After 60 days of the UV aging test, the yellow color index of neat epoxy coatings was 1.6 times that of 0.5 wt% DGO/epoxy coatings. The residual pencil hardness of the 0.5 wt% DGO/epoxy coatings was three levels higher than that of neat epoxy coatings.
