Title (EN) IMPROVEMENTS RELATING TO CURING OF SYNTHETIC RESIN SYSTEMS, FOR EXAMPLE, IN THE LINING OF PIPELINES AND PASSAGEWAYS
(FR) AMELIORATIONS RELATIVES A LA POLYMERISATION DES SYSTEMES DE RESINE SYNTHETIQUE, PAR EXEMPLE POUR LES REVETEMENTS INTERIEURS DES TUYAUX ET DES CONDUITES
Abstract:
(EN) The invention provides that a laser light used to cure synthetic resin systems, in particular those systems which are used in the lining of pipelines or passageways. The synthetic resin system is of the curable type, such as polyester or epoxy, and has a catalyst protected from causing premature curing of the resin by being contained in particles. Laser light is focussed so as to activate the particles which has the effect of releasing the catalyst so that it can commence doing its work of curing the resin, but there is no wastage of light energy, as is common with known systems in heating up the resin.
(FR) L'invention concerne l'utilisation d'une lumière laser pour polymériser les systèmes de résine synthétique, notamment ceux destinés à revêtir intérieurement les tuyaux et les conduites. Le système de résine synthétique est de type polymérisable, polyester ou époxy par exemple, et comporte un catalyseur qui ne peut pas provoquer de polymérisation prématurée de la résine du fait qu'il est contenu dans les particules. La lumière laser est focalisée de façon à activer les particules, ce qui a pour effet de libérer le catalyseur, qui peut alors commencer à polymériser la résine; mais il n'y a pas de gaspillage d'énergie lumineuse, comme c'est souvent le cas avec les systèmes de polymérisation de résine connus.
