    • PROBLEM TO BE SOLVED: To provide an alkali detergent composition which is preferable for washing a metal having corrosion sensitivity in alkali solution, especially for washing a soft metal such as aluminum or its alloy, or a galvanized steel such as a zinc-coated steel, and which can wash the inside surface that is difficult to be reached without additional mechanical treatment.SOLUTION: This invention relates to: a composition for washing a surface having corrosion sensitivity in alkali solution, which contains at least one kind of an alkali source, and at least one kind of an inorganic salt containing at least one kind of cation selected from elements in the second or third main group of the element periodic table, and thereby which does not contain any triazole and/or any alkali metal borate; an aqueous concentrate containing the composition; a solution to be used containing the composition or the aqueous concentrate; and a method for washing the surface having corrosion sensitivity in alkali solution by using the aqueous concentrate or an optional solution to be used.
    • 要解决的问题:提供一种碱洗涤剂组合物,其优选用于在碱溶液中洗涤具有腐蚀敏感性的金属,特别是用于洗涤诸如铝或其合金的软金属或镀锌钢,例如锌 - 并且可以在没有额外的机械处理的情况下洗涤难以达到的内表面。 解决方案:本发明涉及:含有至少一种碱源的碱溶液中具有腐蚀敏感性的表面的组合物和至少一种含有至少一种阳离子的无机盐 选自元素周期表的第二或第三主族中的元素,从而不含任何三唑和/或任何碱金属硼酸盐; 含有该组合物的含水浓缩物; 包含组合物或含水浓缩物的待使用的溶液; 以及通过使用水性浓缩物或任选的使用溶液来洗涤在碱溶液中具有腐蚀敏感性的表面的方法。 版权所有(C)2012,JPO&INPIT
