powder electrostatic application technology

The technique for environmental protection from heavy metals is proposed in this paper. The objective of this research is development of utilization technology of metal-containing hazardous sewage with the reception of anticorrosive pigments. Zinc containing model solutions and waste water were used for this study. Cobalt was used as a cation chromophore. The method of potentiometric titration has been applied for research of precipitation process.

Basics and distinctive features of contemporary resource and energy saving technology of powder electrostatic application (POESTA) of vitreous enamel coatings are described. Its technological, economic and ecological advantages over slip enamelling in household appliances manufacture, particularly in Ukraine, are discussed. Synthesis principles of special glass frits with high specific electric resistivity for POESTA and results of investigation concerning development and industrial implementation of ground, direct-on and coloured cover enamels for household appliances are given.
