摘　　要：利用扫描电镜、光学轮廓仪等设备研究了基板形貌、锡层厚度、合金层厚度对镀锡板耐黑变性能的影响。结果表明,基板形貌对镀锡板耐黑变性能影响最大,而基板形貌主要受钢板的轧制工艺影响,当平整机采用3.5+3.5μm配辊,1.1%延伸率轧制后所制得的镀锡板,拥有较好的耐黑变性能,黑变发生率由常规配辊的45%降低到6%;当镀锡量由5.0 g·m^(-2)提升至6.1 g·m^(-2)时,耐黑变性能没有明显变化;合金层厚度对于镀锡板耐黑变性能有一定影响,其由0.41 g·m^(-2)提升至1.23 g·m^(-2)时,黑变发生率由6.7%降低至1.2%。The effects of substrate morphology,tin layer thickness and alloy layer thickness on the blackening resistance of tinplate were studied by scanning electron microscope,optical profiler and other equipment.The results show that the substrate morphology of tinplate has the greatest influence on the black stain resistance of tinplate,while morphology of tinplate is mainly affected by the rolling process of steel plat.When the tinplate is made of 3.5+3.5μm roll matching and 1.1%elongation,the tinplate has good blackeninng resistance,the occurrence rate of black stain resistance of tinplate is reduced from 45%of conventional roll matching to 6%.When the tin plating amount increased from 5.0 g·m^(-2)to 6.1 g·m^(-2),the black stain resistance has no obvious change.The thickness of alloy layer has certain influence on the blackening resistance of tinplate,when it increased from 0.41 g·m^(-2)to 1.23 g·m^(-2),the occurrence rate of black stain resistance of tinplate decreased from 6.7%to 1.2%.
