| description | The invention relates to a method for removing brass from steel fibres coated with brass intended for reinforcing polymerised articles, the method comprising at least one electrochemical treatment step in which the steel fibres are immersed in a treatment bath comprising a solution of soda at a concentration of between 10 and 1000 g/l while being subjected to an anode current, wherein the mass current intensity is between 1 to 2500 A/kg of steel fibres, the dwell time of the steel fibres in the bath being at least equal to 7 minutes and the treatment temperature being at least equal to 30°C.
L'invention concerne un procédé de délaitonnage de fibres d'acier revêtues de laiton destinées au renforcement d'articles polymérisés comprenant au moins une étape de traitement électrochimique dans laquelle les fibres d'acier sont immergées dans un bain de traitement comprenant une solution de soude à une concentration comprise entre 10 et 1000 g/l en étant soumises à un courant anodique, l'intensité de courant massique allant de 1 à 2500 A/kg de fibres d'acier, le temps de séjour des fibres d'acier dans le bain étant au moins égal à 7 min et la température de traitement étant au moins égale à 30°C. |
