通过对锡材表面发黄现象及机理研究,在其加工过程的不同阶段做抗氧化处理,后将其放入恒温恒湿箱中进行加温加湿对比试验。记录在相同加温加湿条件下锡材表面开始发黄时间。结果表明,用0.1%~0.3%的抗氧化处理剂G在锡材成型后进行抗氧化处理对延缓锡材表面发黄现象具有良好的效果。 By studying the phenomenon of yellowing on the surface of tin material and its mechanism, anti-oxidation treatment was carried out at different stages of its processing, and then placed in a constant temperature and humidity box for comparison of heating and humidifying. Record in the same heating and humidifying conditions tin surface yellowing time. The results show that 0.1% ~ 0.3% anti-oxidant treatment agent G has good effect on retarding the yellowing on the surface of tin material after anti-oxidation treatment.
