中文摘要:
      为配制出成膜质量更佳的涂装用磷化液,从锌系磷化膜形成机理出发,分析了改善其低温成膜效果的可能途径;通过高效促进剂和磷化工艺参数的优选,开发出一种实用性强的钢铁工件涂漆前处理——含稀土复合促进剂的低温锌系磷化新工艺。研究表明:家电外壳广泛采用的冷轧A3钢薄板经此LZP快速磷化液处理后,所得防锈涂装底层实用效果良好。在含1.0-2. Og/L稀土促进剂的磷化液中,A3钢薄板经400C、3- 4min喷淋处理后可获得厚约3μm的磷化膜,其结晶细小致密、与基体结合力强、抗蚀性好。磷化后经在线涂漆,对应漆膜抗冲击性、耐蚀性和附着性能良好。
英文摘要:
      The phosphating thermodynamics was discussed to conclude that rare earth is valid for improving the quality of phosphate coating for anchoring layer. With multiplex accelerant containing rare-earth compound , a novel anticorrosive zinc-phosphating process at the low temperature, very feasible as painting pretreatment of steel and iron parts, was developed and optimized. The experimental results show that the phosphating effect is very good for cold-rolling A3 thin steel plate used widely to home appliances crust. With the fast LZP zinc-phosphating solution including l. 0 ~ 2. Og/ L rare-earth accelerant, the phosphate coating thickness about 3μm is obtained at 400C in 3 -4min, which is fine and compact crystal, highly adhesive to substrate of A3 steel plate and excellent corrosion resistance. Moreover, experimental results of online painting show that the paint coating has excellent characteristics of shock resistance , corrosion resistance and adhesion.
