Intumescence (chimie)
Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : Intumescent coatings provide a highly effective means of protecting substrates form fire damage. All these coatings undergo a similar series of reactions in a fire, creating an insulating foam many times thicker than the original coating. They are commonly applied to steel and wood substrates, but other application areas include electrical cables, textiles and intumescent gel coats for composites.

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.

Poly(4-vinylpyridine-méthacrylate de butyle)
Résistance à la fissurationIndex. décimale : 667.9 Revêtements et enduits Résumé : Composite coating of reduced graphene oxide (RGO) and poly (4-vinylpyridine-co-butyl methacrylate) (PVPBM) on copper was produced by electrophoretic deposition (EPD) technique. The structural and morphological characterizations of the RGO-PVPBM coating were carried out using a Raman spectrometer and a field emission scanning electron microscope, respectively. The thermal stability of the coating was analyzed by thermo-gravimetric analysis, and the corrosion resistance properties were examined by potentiodynamic polarization measurements and electrochemical impedance spectroscopy in 3.5% NaCl solution. At optimal EPD conditions of operating voltage of 5 V and total deposition time of 15 min, a uniform crack-free RGO-PVPBM composite coating is obtained. The microscratch experiment has shown an enhancement in the crack propagation resistance of RGO-PVPBM composite coating up to 3.7 times and adhesive strength increased ~2 times compared to PVPBM coating, thereby making it a potential damage tolerance surface coating on Cu substrate. The potentiodynamic measurements clearly show that RGO-PVPBM acts as a protective coating for Cu in 3.5% NaCl solution. The corrosion inhibition efficiency for RGO-PVPBM coating was calculated to be 95.4% which clearly indicates that the tailored RGO-PVPBM composite is an excellent barrier coating to ion diffusion and corrosive electrolyte with considerably enhanced corrosion resistance.

MortierIndex. décimale : 620.13 Matériaux de construction : pierre, ciment, béton, liants de Résumé : This study investigates the potential use of Diss fibers as a sustainable alternative in eco-construction and civil engineering. The research introduced Diss fibers as aggregates, partially replacing conventional sand in mortar by volume with proportions of 1/3 and 2/3, aiming to create an eco-friendly and lighter mortar. In this context, various properties of the fresh mortars, such as density, workability, and occluded air content, were examined. Additionally, the mechanical performance in the hardened state, including compressive and flexural strengths, was evaluated. Durability parameters such as water absorption, capillary absorption, and resistance to aggressive media were also assessed. The results demonstrated that mortars incorporating Diss fibers were lighter and more workable. The inclusion of these fibers enhanced the flexural strength and chemical resistance, as evidenced by the low percentages of mass loss in aggressive solutions such as HCl and CH3COOH. However, the introduction of the fibers negatively influenced the mechanical resistance and water absorption—both by immersion and capillarity—due to the porosity introduced into the composites.
