| Résumé : |
Innovative recycling technology, transforming coal-fired power station fly ash from a waste into valuable eco-mineral fillers and extenders for industrial scale brings a great source of inorganic mineral filler. Fly ash needs to be considered as a "resource", and hence it just can't be "disposed" off but should be "utilised" fruitfully. By using this mineral filler we can cut production costs, increase margins and improve profitability, white simultaneously greening supply chain. Fly ash / Cenospheres can bring a wide range of important benefits through lover energy usage or higher loadings, or as a result of the replacement of more expensive minerals. These benefits depend on the polymer, application and materials currently being used ; whether flexible or rigid, thermoplastic or thermosetting and replaced conventional and man-made inorganic fillers and extenders such as talc, GCC, glass fibres, glass microspheres, barytes, dolomite, clay. Fundamental advantages of using fly ash as filler are being spherical ; relatively hard ; and free flowing. By beneficiation process removal of any residual surface alkali salts results in enhanced performance of fly ash filler in coatings. |
