METHOD FOR CHEMICAL PROTECTION OF CURRENT-CONDUCTING METAL STRUCTURES FROM ELECTROSTATIC FILTERS FOR WET GAS CLEANING OF SULPHURIC ACID MIST

摘要

FIELD: metallurgy.SUBSTANCE: invention can be used for disposal of gases of zinc production into sulphuric acid. Method involves preparation of surface metal structures of electric filter and applying protective fiber glass coating based on binder in form of Derakane Momentum 411-350 resin by successively depositing layers of said resin and glass voile, which is repeated until creation of protective coating with thickness of 5 mm, on which layer of resin and lead bus width 20 mm and thickness 4 mm are applied, which is fixed by depositing on its sides of said additional layer of resin and glass voile.EFFECT: invention provides longer life of sulphuric acid production equipment.1 cl, 1 dwg, 1 ex
