Titre : Optimising formulations : new technologies for measuring dynamic surface tension simplifies the analysis of wetting properties Type de document : texte imprimé Auteurs : Volker König, Auteur Année de publication : 2002 Article en page(s) : p. 14-16 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Good adhesion assumes good wettting and requires low surface tension. Solvent-based systems have low surface tension to begin with. Water-based systems need surface tension reducing additives. A new method of measuring now makes it possible to analyse the effect of the additive in the formulation and this way to reduce otherwise necessary costly tests on printers of printing presses. Thus, measuring dynamic surface tension can save time and money. Note de contenu : - Time dependent changes in the surface tension decide on the wetting behaviour
- Measurable time dependency of the surface tension by varying the bubble lifetime
- Analysis shows : the initial wetting might be identical but the spreading behaviour can still be different

Titre : UV curing under carbon dioxide - available to everyone Type de document : texte imprimé Auteurs : Erich Beck, Auteur Année de publication : 2002 Article en page(s) : p. 24-32 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : UV curing of coatings under inert, i.e. oxygen reduced, atmosphere is usually performed under nitrogen, with considerable process equipment. However, with heavier-than-air CO2 as the inert gas, excellent curing results can be obtained, in particular for 3D substrates, with very simple equipment - a CO2 bath and simple UVA lamps. With this technique, formulations can be greatly simplified and allow for much more variation. Note de contenu : - Oxygen inhibits UV curing
- Carbon dioxide opens up nex prospects
- 3D UV becomes simpler
- Surface curing is facilated
- Additional possibilities for coating formulations
- Matting can be easily adjustedEn ligne : https://drive.google.com/file/d/1lVZdSmmNS2FN4Z249hCGSQzu6MLm-8-y/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10869

Titre : Spherical and lamellar zinc dust Type de document : texte imprimé Auteurs : Libuse Hochmannova, Auteur Année de publication : 2002 Article en page(s) : p. 36-41 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Zinc dust has been used as a high quality pigment for corrosion protection in primer coatings for steel for many years. Two types of zinc particles are produced: spherical and lamellar. Both, alone and in combination, have different influence on the viscosity behaviour, drying time, impact resistance and anticorrosive effect of a paint. This study shows the differences and that the combination of 1/3 spherical and 2/3 lamellar zinc dust have shown the best anticorrosive effect. Note de contenu : - Zinc coatings are porous
- Zinc primer with CPVC for electric conductivity
- Primer with a combination of spherical and lamellar zinc dust
- Viscosity of primers with spherical zinc dust increases with higher PVC
- Particle shape is important for coatings properties
- Lamellar shape reduces drying time and improves impact resistance
- Panels preparation for anticorrosive tests
- Combination of spherical and lamellar zinc dust improves result of salt spray (fog) test
- Good results in humidity cabinet
- Good adhesion with lamellar zinc dustEn ligne : https://drive.google.com/file/d/1cSStjiBmWQfb02eBMzufjESLxd9PU8AN/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10871

Titre : Why organic pigments are not POPs Type de document : texte imprimé Auteurs : Eric A. Clarke, Auteur Année de publication : 2002 Article en page(s) : p. 42-45 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The properties of most organic pigments make the possibility of their bioaccumulation very unlikely, and experimental evidence supports this view. As our author argues, they should therefore not be classified as Persistent Organic Pollutants (POPS), nor as Persistent, Bioaccumulative, and Toxic (PBT) substances. Note de contenu : - No evidence for bioaccumulation in fish
- Aquatic toxicity studies are difficult
- "Organic pigments not harmful to aquatic environment"
- Partition coefficient no useful indicatorEn ligne : https://drive.google.com/file/d/1rUJXYQeFrlQiV0h3ht_-DThWN-az3e69/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10872

Titre : Benefits of cycle time reduction Type de document : texte imprimé Auteurs : I. F. Harrison, Auteur ; John E. Dunstone, Auteur Année de publication : 2002 Article en page(s) : p. 46-49 Langues : Anglais (eng) Catégories : Temps de cycle (production) -- Réduction Index. décimale : 667.9 Revêtements et enduits Résumé : From the customer's perspective, the cycle time is the time between placing an order and receiving the goods. In some cases it is between making an enquiry and receiving the goods, including a product development element such as a new shade. These activities impact on both the costs and the inventory levels that the business has to support as well as on competitiveness. Note de contenu : - Getting the best out of existing product range
- Understanding the situation with flow charts
- Symptoms of cycle time delays
- Concept of dynamic cycle time
- Priority changes cause inefficiencies
- Elimination of typical problems is the first taks
- Inventory replenishment
- Inventory policy
- Transferring production between factories
- Symptoms which indicate the need for a cycle time reduction project
