The Research of Technological Solutions from etching bathes of Hot-dip Galvanizftion
The aim of the research was to find the experimental procedure for iron, orthophosphoric acid and hydrochloric acid determination in etching solutions for hot-dip galvanization. We have changed and adopted existing standard methods of determination for industrial use. The ways were found to eliminate the admixtures influence on controlled characteristics assessment. Based on the researching methods we have performed the serial technological control of main controlled characteristics of etching solutions for hot-dip galvanization. We have estimated the minimal and maximal values for controlled characteristics, and also we have found the reasons of divergence between observed characteristics and their optimal values.
