    • The present invention relates to a solution for use in the electroplating of tin and tin alloys comprising a basis solution which includes fluoboric acid or an organic sulfonic acid or one of their salts, divalent tin ions, and an antioxidant compound which includes a transition metal selected from the elements of Group IV B, V B or VI B of the Periodic Table in an amount effective to assist in maintaining the tin ions in the divalent state. Another aspect of the invention relates to a method for preventing, reducing or minimizing the oxidation of tin ions in an acid electroplating solution by adding one of these antioxidant compounds thereto. This method is effective in certain basis solutions even when iron contamination or high oxygen levels are present.
    • 本发明涉及一种用于锡和锡合金电镀的溶液,其包括基础溶液,其包含氟硼酸或有机磺酸或它们的一种盐,二价锡离子和包含所选择的过渡金属的抗氧化剂化合物 从元素周期表第ⅣB族,Ⅴ族或ⅥB族元素中以有助于维持二价态的锡离子的量。 本发明的另一方面涉及一种通过向其中加入这些抗氧化剂化合物之一来防止,减少或最小化酸性电镀溶液中锡离子氧化的方法。 即使存在铁污染或高氧含量,该方法在某些基础溶液中也是有效的。

    • An improved process for reflowing tinplate by treating a matte finish of tinplate with a flux, and reflowing the fluxed matte tinplate to produce bright tinplate, wherein the flux is a naphthalenesulfonic compound, preferably having the a naphthalene ring which is substituted with at least one --SO.sub.3 M group where M is hydrogen, an alkali metal or an alkaline earth metal and is optionally substituted with at least one hydroxy group. The flux is preferably applied to the matte tinplate in an aqueous solution which may contain an acid. The most preferred fluxes are 2-naphthol-6,8-disulfonic acid, 1-naphthol-3,6-disulfonic acid, and dipotassium 2-naphthol-6,8-disulfonate.
    • 一种通过用助焊剂处理马口铁的无光饰面的回流马口铁的改进方法,并且回流焊剂的无光泽马口铁以产生光亮的马口铁,其中助熔剂是萘磺化合物,其优选具有被至少一个 - SO 3 M基团,其中M是氢,碱金属或碱土金属,并且任选被至少一个羟基取代。 助焊剂优选以可含有酸的水溶液施用于无光泽马口铁。 最优选的助熔剂是2-萘酚-6,8-二磺酸,1-萘酚-3,6-二磺酸和2-萘酚-6,8-二磺酸二钾。
