| 摘 要： | 通过比较多种防锡变色剂的防变色效果,发现乙二胺四甲叉膦酸(EDTMP)是一种优良的防锡变色剂。用XPS、AES及Raman光谱探讨了EDTMP的防变色机理,结果表明EDTMP在锡表面形成了一种耐蚀性保护膜。在深度剖析曲线的元素组成近似恒定区测得膜的相对原子浓度(A.C.％)为:O 48.0％;Sn 10.7％;N 7.7％;C 23.1％;P 10.5％。

| Abstract: | It is found by accelerating tarnish test of cysteine solution that ethylenediamine tetra-methylene phosphoric acid (EDTMP) was an excellent antitarnishing agent for tinplate. Theantitarnish mechanism of EDTMP for tinplate has been studied by XPS, AES and laserRaman spectromety. A complicated anticorrosion film was formed on tin surface. The rela-tive atomic percent contents (A. C. %) or the film obtained from the constant element como-sition region of the profile curves were O 48.0%,Sn 10.7%, N7.7%,C 23.1% and P10.5. |
