Abstract
본 발명은 인산염계 무기염이 함유된 스팡글 미세화 용액의 농도 및 그 용액의 인산이온을 제어하므로서 종래의 분사용액과 동일한 조건으로 분사하여 미니스팡글 용융아연 도금강판을 제조했을 때와 비교하여 스팡글 크기가 매우 미세하면서도 표면 광택도가 우수한 미니스팡글 용융아연 도금강판을 제조할 수 있는 분사용액을 제공하고자 하는데, 그 목적이 있다.
본 발명은 용융아연 도금강판 표면상의 스팡글을 미세화하는 수용성 인산게 무기염이 함유된 스팡글 미세화 용액에 있어서, 상기 수용성 인산계 무기염의 농도가 0.5~5.0wt%이고, 그 용액중의 인산이온이 모두 H2PO4-화학종인 용융아연 도금강판의 스핑글 미세화 용액에 관한 것을 그 요지로 한다.
