摘要
针对中温磷化技术的缺点,研制出一种低温磷化加速剂。实验结果表明,将某种有机化合物与硝酸钠进行混合而制成的复合加速剂,在处理温度为30~40℃、处理时间为3 min 的条件下,可以获得性能良好的磷化膜。
Aiming at solving the problems in medium-temperature bonderizing tech- nology,a low-temperature accelator(PL)with high stability is developed.Experi- mental results show that applying this accelator made from mixing of some organic compound and sodium nitrate can obtain good phosphate coating under treatment temperature 30~40℃ and treatment time 3 min.
