Sol-gel, ProcédéIndex. décimale : 667.9 Revêtements et enduits Résumé : A nanocomposite suspension made of redispersable crystalline In2O3·Sn (ITO) nanoparticles and a hybrid organic-inorganic additive was prepared to obtain single 600nm-thick, transparent, electrically-conducting layers. The rheology of the suspension was adjusted so that the formulations could be used to coat different glass and polymer substrates and foils using wet chemical deposition techniques such as spin coating, dip coating, spray coating and web coating. The optical properties (transmission, reflection, absorption) showed that the layers transmitted more than 87% in the visible range, acted as infrared (IR)-shielding coatings for (λ>1.5µm, and effectively reduced the intensity of solar light (Air Mass (AM) 1.5 Global solar spectrum). At the same time, the layers acted as UV blockers for wavelengths less than 400nm, protecting the polymer substrates and foils from degradation when exposed to UV irradiation. The layers exhibited a high conductivity (σ- 1100Sm−1) which made them useful for electrostatic and antistatic purposes as well as for devices that require a transparent conducting coating with sheet resistance higher than a few kΩp[. Furthermore, the layers showed excellent adhesion on all substrates and high resistance against abrasion and weathering degradation, results that are quite promising with respect to their outdoor use.

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.

RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : The handling of sticky raw material can cause problems during operation of process equipment in the cement production industry. These handling problems are generally observed when raw material (e.g., wet clay) sticks to machine walls and causes blockage of outlets. This leads to frequent production shutdowns and expensive cleaning operations. In this work, the effects of surface material and process parameters on the friction forces between wet clay and surface were investigated. Various surface materials and clay impact speeds were investigated. The results demonstrate that not only the equipment surface material but also the surface roughness influences the observed frictional behavior. The ranking of the materials in terms of effective static friction coefficients fell in two groups with equal performance within the group: (1) Two Teflon-based coatings (Accofal 2G54 and Accolan LB), polished AISI 304 stainless steel, Matrox lining, and a polyurethane-based coating (best performing surfaces), (2) Mild steel, a silicone-based coating, and AISI 304 stainless steel (worst performing surfaces). However, the friction coefficients of the two groups only varied by a factor of two, suggesting that adhesion of wet clay to surfaces is difficult to avoid by the use of coatings.

Revêtement humideIndex. décimale : 667.9 Revêtements et enduits Résumé : Calcite particles coated with nano-silica find use in applications such as enhanced oil recovery, paper-making, and thermal energy storage. In this study, the surface coating of calcite particles by silica nanoparticles (nano-SiO2) in aqueous solutions assisted by a CO2 environment was investigated. The result indicates that the coating performance can be controlled by altering the electrostatic attraction between calcite and nano-SiO2, with the calcite surface charge being the predominant factor. An elevated CO2 partial pressure (up to 3.7 atm) is beneficial for the coating process. However, similar coating performance can be achieved under lower CO2 partial pressures by introducing calcium salt into the aqueous solution. With the addition of 15 wt% of nano-SiO2 in a 6.5 mM CaCl2 solution, a nano-SiO2 loading content of 12.6 wt% (with an average calcite particle size of 6.74 µm) was achieved under 1 atm CO2 pressure after 24 h of the coating experiment. Overall, the coating of calcite surfaces with high contents of well-dispersed nano-SiO2 can be achieved in a CO2 environment, and calcium salts can be used to reduce the required CO2 pressure. As such, it is potentially feasible to integrate wet coating into aqueous carbonation-based CO2 mineralization processes to enhance process economics by making nano-SiO2-coated calcite a valuable byproduct.
