Title (EN) METHOD FOR PROTECTING THE SURFACE OF A SOLDERING BATH
(FR) PROCEDE DE PROTECTION DE LA SURFACE D'UN BAIN DE BRASAGE
Abstract:
(EN) A covering material is used which comprises two superposed unmiscible liquid phases (3, 4) at the soldering temperature. The lower phase (3) is obtained by spreading a powder of a chemically active compound which is solid at room temperature and liquid at soldering temperature, of sebacic acid and/or suberic acid or the esters thereof in the upper phase (4) which is comprised of a liquid synthetic polyalphaolefine.
(FR) On utilise un matériau de recouvrement composé de deux phases (3, 4) superposées non miscibles et liquides à la température de brasage. La phase inférieure (3) est obtenue en répandant une poudre d'un composé chimiquement actif, qui est solide à la température ambiante et liquide à la température de brasage, d'acide sébacique et/ou d'acide subérique ou de leurs esters, dans la phase supérieure (4) qui est composée d'une poly-alpha-oléfine synthétique liquide.
