Abstract

본 발명은 인산염 처리용액의 조건을 최적화하므로서 별도의 설비증설없이 기존의 장치로서 인산염처리를 제공함에 그 목적이 있다. 본 발명은 인산염 처리용액에 있어서, 아연이온농도：4.5∼5.5g／ℓ, 니켈이온농도：0.1c∼0.35g／ℓ 이고, 상기 아연이온농도／니켈이온농도：15∼40 범위이며, 전산도：25∼30, 유리산도：3.4∼4.0 이고, 상기 전산도／유리산도：5.5∼12 범위인 것을 특징으로 하는 아연계 전기 도금강판의 표면외관 특성을 향상시키고 인산염 처리 용액을 제공함을 그 요지로 한다.The present invention aims to provide a phosphate treatment as an existing device without additional equipment by optimizing the conditions of the phosphate treatment solution. In the phosphate treatment solution, the zinc ion concentration is 4.5 to 5.5 g / l, the nickel ion concentration is 0.1c to 0.35 g / l, and the zinc ion concentration / nickel ion concentration is in the range of 15 to 40. The main aspect of the present invention is to improve the surface appearance characteristics of the zinc-based electroplated steel sheet and to provide a phosphate treatment solution: 25 to 30, free acidity: 3.4 to 4.0, and the acidity / free acidity: 5.5 to 12. do.
