Traitement de surface par impactIndex. décimale : 667.9 Revêtements et enduits Résumé : Dust, scale and other residues in blasting abrasives reduce the performance of the blasting machine. For this reason, cleaning the blasting media is particularly important. Tests clearly show that abrasives that are in ideal condition significantly reduce the wear on the blasting wheels.

- The benefits of a perfect curtain of abrasive
- A lasting improvement in the results of the blasting process

ViscositéIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The preparation of a storage-stable abrasive cleaning composition without dolomite as a starting material, in which no or only a very small amount of alkylbenzene acid magnesium salt (Mg-LAS) is present, is achieved by using alkoxylated fatty alcohols. Such a cleaning composition contains 1 to 15 wt.% alkylbenzene acid calcium salt (Ca-LAS) at a proportion of Mg-LAS ≤ 1% of the amount of calcium salt as well as 0.5 to 10 wt.% alkoxylated fatty alcohol.

AcierL'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.

Traîtements de surfaceIndex. décimale : 671.7 Finissage et traitement des surfaces Résumé : When you clean steel by abrasive blasting, you need to produce a finish that will allow maximum adhesion of the coating. Thus, you need to create the specified profile and the specified degree of cleanliness, such as SSPC-SP 10/NACE No. 2, Near-White, or Sa 21/2, Very Thorough (ISO 8501-1).
The abrasive itself will affect both the profile and the degree of cleanliness of the steel. To achieve the appropriate profile, you must use the right size abrasive, and to achieve the specified cleanliness, you must use abrasive that will effectively cut away rust, scale, old paint, and other contaminants that may be on the surface. You also must be sure that the abrasive is clean, so that it does not recontaminate the surface. This bulletin deals with assuring the quality of the abrasive you are using. It will explain how to check for cleanliness, size, and if you are recycling the abrasive, the proper operating mix.Note de contenu : - Documents from the supplier

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Erosion equations were developed to predict the material removal of polyurethane coatings on carbon fiber reinforced plastic (CFRP) surfaces and validated through experimental data. The effects of abrasive properties, process parameters, and organic coating properties (such as fracture toughness and hardness) were considered in the equations. As the erosion angle increased, elastoplastic deformation in the oblique direction and repeated "deformation" in the normal direction were the main reasons for material removal. The ductile erosion behavior was confirmed by experimental data because the maximum erosion rate occurred at an incident angle of 30°. The coefficient and index in the equations were determined by experimental data, and the equations were verified. The developed equations could accurately predict the quantity loss of organic coatings under different particle sizes and particle velocities, and the erosion equations were in good agreement with the experimental data.
