Controlling method of surface treating liquid
专利汇可以提供Controlling method of surface treating liquid专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable the control of the pickling power of surface treating liquid, by making use of the correlation between the current density by the natural potential on a pikling soln. for metal and the rate of dissolution of metal in the pickling soln.
CONSTITUTION: A reference Ag-AgCl electrode 6, a working electrode 7 which is a material to be pickled, and a counter electrode 8 made of platinum are used in a pickling vessel 1 contg. a pickling soln. 2 for metal such as iron and copper, and the natural potential of the material to be pickled is measured with a potentiostat 9. At the same time, the metal 10 to be pickled is put in the soln. 2 and the natural potential of the material to be pickled measured with the potentiostat 9 by using a reference Ag-AgCl electrode 5, a working electrode made of platinum and a counter electrode 3 made of platinum is inputted with constant potential electrolysis device 11 to the electrode 5 and the electrode 4. The electrolytic current corresponding to the pickling capacity of the soln. 2 for the material 10 is inputted through the electrode 4 and the electrode 3 to the device 11, and the electrolytic current density indicating the pickling capacity is displayed and recorded on a recorder 12.
