Machine for localized cleaning, including pickling acid or a composition/mixture of chemical elements with pickling action that is applied by hand or by mechanical instruments to the surface that is to be treated and also contains acid held in a limited quantity in the work position by a cell in material that will withstand the corrosive action of the acid; the cell is of the same volume as the acid used, i.e. it completely fills it with acid and reduces the volume to the volume of the acid contained in the perimeter of the cell projected on the surface to be treated; the acid is activated by the action of a device that activates pickling in its own device. Different constructional forms with electrolytic and/or ultrasound action are described together with aspiration and separation of fumes.
L'invention concerne une machine de nettoyage localisé, comprenant un acide de décapage ou une composition/un mélange d'éléments chimiques ayant une action décapante appliquée à la main ou au moyen d'instruments mécaniques à une surface (5, 46, 64, 73) à traiter. La machine contient également, en position de fonctionnement, un acide en quantités limitées contenu dans une cellule dans un matériau supportant l'action corrosive de l'acide. La cellule a le même volume (7, 47) que l'acide utilisé, c'est-à-dire que la cellule se remplit complètement d'acide et réduit son volume à celui de l'acide contenu dans le périmètre de la cellule projeté sur la surface à traiter. L'acide est activé sous l'action d'un dispositif (11, 68) qui active le décapage dans son propre dispositif. L'invention concerne différentes formes de fabrication ayant une action électrolytique et/ou ultrasonore, ainsi que d'aspiration et de séparation de vapeurs.
