[article]  inINTERNATIONAL SURFACE TECHNOLOGY (IST) > Vol. 11, N° 2 (2018) Titre : Efficient paint coagulation Type de document : texte imprimé Année de publication : 2018 Langues : Anglais (eng) Catégories : Ateliers de peinture industrielle -- Nettoyage Coagulation Entretien et réparations Récupération (Déchets, etc.) Revêtements -- Déchets:Peinture -- Déchets Index. décimale : 667.6 Peintures Résumé : Paint residues and dirt in spray booths can lead to expensive production shutdowns. In order to ensure that processes run smoothly and that maintenance can be carried out as efficiently as possible, high-quality coagulants are needed which are designed for use with the specific type of spray booth. Note de contenu : - High standards for coagulants - Reducing problems and extending water usability - VOC-free and REACH-compliant - Efficient solutions for highly effective processes Fig. 1 : In order to ensure that processes run smoothly and that maintenance can be carried out as efficiently as possible, high-quality coagulants are needed which are designed for use with the specific type of spray booth. - Fig. 2 : In spray booths where the walls and floors are washed with water, the excess paint is trapped, washed out and collected in a tank. The addition of coagulants results in the paint particles combining to form larger lumps and allows them to be removed. - Fig. 3 : If the coagulation is process is ineffective, the paint sludge remains sticky and modern coagulation agents allow the paint sludge to be denatured much more effectively Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30998 [article]

Novel methods for recycling & reusing automotive paint sludge / Shradha Krishna Pednekar in PAINTINDIA, Vol. LXXII, N° 5 (05/2022)  

[article]  inPAINTINDIA > Vol. LXXII, N° 5 (05/2022) . - p. 66-72 Titre : Novel methods for recycling & reusing automotive paint sludge Type de document : texte imprimé Auteurs : Shradha Krishna Pednekar, Auteur Année de publication : 2022 Article en page(s) : p. 66-72 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Automobiles -- Revêtements:Automobiles -- Peinture Boues résiduaires Déchets industriels -- Recyclage Peinture -- Récupération Pyrolyse La pyrolyse est la décomposition ou thermolyse d'un composé organique par la chaleur pour obtenir d'autres produits (gaz et matière) qu'il ne contenait pas. L'opération est réalisée en l'absence d'oxygène ou en atmosphère pauvre en oxygène pour éviter l'oxydation et la combustion (L’opération ne produit donc pas de flamme). Il s'agit du premier stade de transformation thermique après la déshydratation. Elle permet généralement d'obtenir un solide carboné, une huile et un gaz. Elle débute à un niveau de température relativement bas (à partir de 200 °C) et se poursuit jusqu'à 1 000 °C environ. Selon la température, la proportion des trois composés résultants est différente.

This operation is a significant source of sol id waste (paint sludge), liquid waste (booth water) and, when solvent-based paints are used, also volatile organic compounds (VOCs). Mixing and painting operations are major sources of environmental concerns in the shop and can present some of the greatest pollution prevention opportun ities. Taking advantage of opportunities to minimize paint wastes makes sense for business and for the environment. Paint sludge represents an important problem both from a managerial and from an environmental point of view owing to its huge volumes and hazardous characteristics. The main actual fate of automotive paint sludge is the incineration and/or the landfil I disposai but this paper aims to provide an overview of the novel processes developed over the last few years to treat automotive paint sludge in order to recover useful products from the waste or reuse it in the industry of sealants, paints and building materials.

Paint sludge removal in PAINTINDIA, Vol. LXIX, N° 8 (08/2019)  

[article]  inPAINTINDIA > Vol. LXIX, N° 8 (08/2019) . - p. 76-80 Titre : Paint sludge removal : Environment friendly technologies aimed at improving the Environment Type de document : texte imprimé Année de publication : 2019 Article en page(s) : p. 76-80 Langues : Anglais (eng) Catégories : Boues résiduaires Déchets -- Réduction Déchets industriels -- Elimination Industrie -- Pollution -- Lutte contre Revêtements -- Déchets:Peinture -- Déchets Revêtements -- Industrie -- Aspect de l'environnement:Peinture -- Industrie -- Aspect de l'environnement Substances dangereuses -- Elimination Index. décimale : 667.6 Peintures Résumé : A process common to most of the industries is the painting process. It is necessary for the protection as well as for the aesthetic appeal of the products. It is also a well-known fact that this process has a substantial envi ronmental impact. Many technologies have evolved to restrict the impact on environment of spray painting. These technologies focus on restricting the pollution during painting, as well as on the collection & treatment of the post painting waste viz. paint sludge. This article talks about the new technology to effectively collect and treat the paint sludge in order to keep the environnent clean, in the most cost effective manner. Not many like to talk about paint sludge. It is still considered a menace and, at times, simply disregarded. Unfortunately, this does not solve the problem of removing the sludge effectively and disposing it in the best possible manner that has minimum impact on the environment. Presently, the rules are getting stringent and it is the responsibility of the one who creates the sludge, to collect it and hand it over to government appointed agencies for an environment friendly disposal. This may sound simple, but the daily "collection" of a relatively difficult-to-handle sticky mass, in the most environment friendly and cost effective manner is surely a challenging task ! In order to understand the state-of-art technology and equipment developed for the paint sludge removal, it is important to list down the major considerations, based on which efficient sludge collection systems are designed. Note de contenu : - a. Type of paints used - b. Quantity of paint sprayed - c. Transfer efficiency of paint application - d. Type of chemicals used - e. Type & no. of paint booths - f. Centralized sludge collection tank capacity & design - g. Amount of water in circulation - h. Paint shop layout - Objectives - Process of operation : A. Denaturation - B.
