Title (EN) SEALING LIQUID FOR ANODIC OXIDE COATING FILMS OF ALUMINUM ALLOY, CONCENTRATED LIQUID AND SEALING METHOD
(FR) LIQUIDE D’ÉTANCHÉITÉ POUR FILMS DE REVÊTEMENT D’OXYDE ANODIQUE D’ALLIAGE D’ALUMINIUM, LIQUIDE CONCENTRÉ ET PROCÉDÉ D’ÉTANCHÉIFICATION
(JA) アルミニウム合金の陽極酸化皮膜用封孔処理液、濃縮液及び封孔処理方法
Abstract:
(EN) The present invention provides a sealing liquid which does not contain a nickel salt but is capable of achieving a sealing performance equivalent to that in cases where a sealing liquid containing a nickel salt is used, and which enables an anodic oxide coating film sealed therewith to exhibit excellent contamination resistance. The present invention provides a sealing liquid for anodic oxide coating films of aluminum alloys, which contains a metal salt, a pH buffering agent and a surfactant, and which is characterized in that the metal salt is at least one salt selected from among alkali metal salts and alkaline earth metal salts.
(FR) La présente invention concerne un liquide d’étanchéité qui ne contient pas un sel de nickel mais qui permet d’atteindre une performance d’étanchéité équivalente à celle obtenue dans les cas où un liquide d’étanchéité contenant un sel de nickel est utilisé et qui permet à un film de revêtement d’oxyde anodique étanchéifié par ce dernier de présenter une excellente résistance à la contamination. Le liquide d’étanchéité pour des films de revêtement d’oxyde anodique d’alliages d’aluminium selon la présente invention contient un sel métallique, un agent tampon de pH et un tensioactif et est caractérisé en ce que le sel métallique est au moins un sel choisi parmi les sels de métaux alcalins et les sels de métaux alcalinoterreux.
(JA) 本発明は、ニッケル塩を含有しない封孔処理液であって、ニッケル塩を含有する封孔処理液を用いた場合と同程度の封孔性能を付与することができ、且つ、封孔処理された陽極酸化皮膜が優れた耐汚染性を示すことができる封孔処理液を提供する。 本発明は、金属塩、pH緩衝剤及び界面活性剤を含有するアルミニウム合金の陽極酸化皮膜用封孔処理液であって、 前記金属塩は、アルカリ金属塩及びアルカリ土類金属塩より選択される少なくとも1種である、ことを特徴とする封孔処理液を提供する。
