Paint & powder features

Relevancy:  

Testing of paint coatings can be based on use of test coupons or panels. The validity of comparative such tests depends on the application process itself being reproducible. A device for ensuring this is described (www.intec-lackiersysteme.de). Powder coatings exposed to sulphur hexafluoride gas. This is widely used in electrical switchgear, transformers etc as insulating medium. Testing of powder coatings in this environment is detailed. 10 standards are listed, mainly DIN EN ISO, for coating quality and outcome of testing to each of these in SF6 is shown. A test chamber is shown and results of cross-hatch tests illustrated. The behaviour of coatings when exposed to arcing is discussed, the chemical reactions taking place are shown. Graph shows the exceptionally good properties of SF6 in quenching arc breakdown. 3 refs. Note on importance of paint agitation, esp. in larger plants, to avoid defects such as haze or cratering. Stirring speed must be optimised (www.oltrogge.de) Visit to powder coater where masking, suspension of the work in the spray chamber and electrical contacting (for electrostatic) are given great care. Interview with specialist in the light of the dramatic upturn in business for German industry, here in the field of paint & powder spray application equipment.

Visit to German manufacturer of automotive rear axles where electrocoat painting is followed by conventional painting. Visit to Opel car plant where tri-cation phosphating has been replaced with silane pre-treatment. Visit to Slovak KIA automotive plant where new paint colour change over involves a loss of only two ml of paint with reduced maintenance. Visit to plant where automotive components are UV painted including brake discs and interior components. Various cost savings including drying are identified. Visit to plant where automotive panels are manufactured from pre-painted coiled steel. Photos show powder coating of edges using pulsed high voltage. A new powder formulation allows very rapid curing. A new approach to infra-red curing is shown with graphs plotting paint viscosity and temperature as the coated work proceeds through the infrared heating zone. Six separate stages in these are shown and idealised paint coating cross-sections show melting, degassing and the final cross-linking to form a smooth coat. Note describes new family of powder coatings for architectural external applications including cladding. New hand-held powder gun Opti-Flex 2 from ITW Gema can handle the most difficult powders.

Relevancy:  

Notes on: remote monitoring of a paint line by on-line methods. Networks, monitoring points & software are discussed. New German contract coater who did not opt for continuous, but rather "island" processing with paint robots. Photos & layout are shown. New BMW automotive powder coating plant. Powder handing equipment is shown in detail, incl. pumps and classical Venturi powder transfer and new dense-flow method. Case study of new powder plant for air-conditioner mfrs. The ITW-Gema equipment is detailed. Powder coating & cleaning of architectural cladding. Coating system differs from that used in automotive, and the shape of the cleaning abrasive particles is critical. Table sets out coating & cleaning costs for a 10 year cycle and new weathering resistant powder has 3-5 times the life of conventional types, in Florida atmospheric exposure test. Benefits of new type powders for builders & architects are listed..

Case study on painting of aluminium automotive wheels with 9-stage pretreatment line and spray booth management with minimal water change. Computer control & visualisation throughout. New approach to spray guns which are neither low pressure (LP or HVLP) nor high-pressure, but which use intermediate air pressures. High application rate, efficient use of material & environmental benefits are claimed. (www.walther-pilot.de). Feature urging world paint industry to embrace Sustainable Development (or suffer the consequences). Statistics suggest that from 1988 to 1998, there was no significant reduction in VOC (organic solvent) emissions. Cites research suggesting (with graph) that technical innovations are now less important than environmental effects, and sustainable development and marketing are now key factors. Graph shows concept of Eco-efficiency and how it is defined. Note summarises R&D, now 25 years established, at Fraunhofer IPA. Progress report on powder coating. Graph compares tribo, corona & corona classic plotting film thickness vs. time (0 to 60 secs). Issues such as multilayer coatings, interfering back-spray effects & non-ionisation of air are noted. 4 photos show surface craters using different guns & spray techniques. Report on new Wagner control unit for powder coating which economises powder use.
