Titre : New surface coatings developed from plant based waste materials for bamboo protection Type de document : texte imprimé Auteurs : V. Sorna Gowri, Auteur Année de publication : 2000 Article en page(s) : p. 35-44 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Matériau revêtement' Peinture Liant 'Matière première' 'Déchet agricole' Utilisation Bambou Préparation Feuil 'Propriété mécanique' chimique' 'Résistance Index. décimale : 667.9 Revêtements et enduits Résumé : The objective of the present study is the utilisation of agro-wastes, like Bhilawanut Shell Liquid (BSL) and Cashewnut Shell Liquid (CNSL) to develop surface coatings for the protection of bamboo surfaces from corrosive environments. As traditional bamboo coatings have the disadvantages of leachability and poor resistance to corrosive environment, it is necessary to develop alternate coatings with better adhesion properties for the protection of bamboo. BSL is an indigenous extract from the shells of Semecarpus anacardium and CNSL is a waste product obtained from the cashew industry. Both BSL and CNSL exhibit the unique properties of ortho dihydric phenol, which can be utilised profitably in the coatings industry. Surface coatings based on BSL and CNSL were prepared from formaldehyde, styrene, hexamine and epichlorohydrin. These coatings were applied on bamboo, and the performance of the coatings was evaluated by determining their physical, chemical and mechanical film properties. The coatings were also characterized by employing IR, NMR and scanning electron microscopical studies.

Titre : Intumescent coatings in the service of fire protection Type de document : texte imprimé Auteurs : Upadhya, S. C., Auteur Année de publication : 2000 Article en page(s) : p. 45-52 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Matériau revêtement' 'Sécurité incendie' 'Protection feu' 'Peinture ignifuge' intumescente' Formulation 'Mécanisme action' Propriété Index. décimale : 667.9 Revêtements et enduits Résumé : An explicit endeavour has been made relating to the study of intumescent coatings. Their phenomenon, composition, mechanism of intumescence are reviewed, followed by a discussion of the use of thermal analysis to investigate the mechanism of decomposition of intumescent coating. A brief review of types of fire retardant coatings is discussed. Also requirements of building regulations, char properties of intumescent coatings, evaluation and Fire Test Standards are presented. Intumescent coating systems with various types of intumes cent coatings and finally applications with off-site advantages is given. Note de contenu : - TYPES OF FIRE RETARDANT COATINGS
