Abstract

DEVICE FOR PROTECTION OF ELECTROLYTE AGAINST EVAPORATION, including floats with displaced center of gravity, characterized in that, in order to increase protection efficiency and reduce heat transfer to the environment, it is equipped with protective screens made in the form of separate plate elements connected to the floats, while the ratio of the diameter of the circle inscribed in the protective shield to the diameter of the circumscribed circumference of the floats is M-B9.

The device works as follows. In the electrolyte bath 5 of the required temperature, the electrolyte surface is covered with a layer of floats 1, for example polyethylene with an offset center of gravity 2 and secured to them with protective shields 4. Then the part is immersed between free-floating balls, the screens of which overlap each other and create a solid surface of protection. Example. Conduct experiments with etching aluminum parts.
