Titre : A case of conditioning or extrapolate at your peril Type de document : texte imprimé Année de publication : 2001 Article en page(s) : p. 73-74 Langues : Anglais (eng) Catégories : Cuirs et peaux
Essais (technologie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the leather business, to achieve comparability, leathers are tested under conditions and thus it is possible to compare a leather in Europe, Asia or America and ensure a level playing field.
The next question that arises is what conditions to choose? Since much of the physical testing was originally done in Northern Europe, conditions were chosen which represented the average conditions in that area. These were a temperature of 20°C and a relative humidity of 65%.Note de contenu : - Different conditions - different performance

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Most water-based architectural stain blocking primers typically have only moderate stain blocking performance, and they are designed to lock stains in the primer coat rather than block stains. This leads to a major performance difference compared to solvent-based primers. Since the stain is visible in the dry film when a bleeding substrate is coated with water-based primer, the painter cannot tell with any degree of certainty if the stain will migrate into the topcoat. Novel cationic water-based primers offer far superior stain blocking and are like solvent-based primers because many stains are blocked by the primer coat rather than locked into the primer coat. For these cationic primers, however, manufacturing procedures and raw materials are different from those typically used in conventional anionic architectural coatings.

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Paint performance can be adversely affected in many different ways by poor adhesion. High solids and waterborne coatings are especially liable to adhesion failures. A novel type of adhesion promoter was tested in a liquid epoxy system on different substrates, including deliberately contaminated or rusted steel. Significant improvements to flexibility, adhesion and corrosion resistance were noted. Note de contenu : - Surface preparation : always important, today critical

Traction (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : Photoluminescent dyes (aminofluorene, naphthalimide, naphtholbenzein, or phenosafranine) were grafted to polyurethane using an allophanate linkage. The photoluminescence properties and the shape recovery effects of polyurethane samples were investigated. The polyurethane was composed of 4,4?-methylenebis(phenylisocyanate), poly(tetramethyleneglycol), and 1,4-butanediol. The dyes were linked through an extra 4,4?-methylenebis(phenylisocyanate) and the carbamate moiety of the polyurethane chains. Polyurethanes with various dye contents were characterised, and the shape recovery and photoluminescence properties were compared. In the case of the tensile mechanical properties, the highest maximum stress was 56 MPa, and the strain remained > 1500% for the entire series. The shape recovery improved as the test cycle was repeated, with up to 100% recovery being achieved, but shape retention decreased as the dye content increased. Finally, the photoluminescence of the polyurethanes was demonstrated by a luminescent light-emission test, together with pH indication capability and the preparation of non-woven fibre using the electrospinning method.

Traction (mécanique)Index. décimale : 677.4 Textiles artificiels Résumé : Textile high-performance filament yarns are used in a wide variety of technical application areas in which they are exposed to extreme thermal stresses. For the designing of the textiles strength members, knowledge of their material behavior under high temperatures is absolutely crucial. This paper gives an overview of current research in the development and realization of test methods for a reliable determination of the tensile-mechanical behavior of textile high-performance fiber materials under extreme thermal stresses.
