PROCEDE DE PROTECTION ANTICORROSIVE DES POMPES DE CYCLAGE DU FLUOR
The process comprises coating of the pump ebonite with three layers of protective film to a total thickness of 4.0 mm. This increases pump service life by a factor of 1.5-2. Fluorine is recovered from phosphoric acid mfr. and from fluorine salt prodn. based on hexafluoro silicic acid with reduced da...
