For the purposes of hot dip galvanizing at ESCON JSC, minimal zinc purity of 99,995% is allowed for application.
For protecting metal structures surface from external impact advanced technologies are used at JSC "Plant ESCON": hot dip galvanization and painting.
Hot dip galvanization line (by KOERNER, Austria) with the biggest zinc bath in Russia has a capacity of automatic galvanization of 40 000 t per year and ensures perfect quality of zinc coating after first dipping.
High quality aesthetic and durable zinc coating is achieved through using alloys from leading world manufactures in zinc melt.
In order to ensure additional protection of zinc-plated surfaces, ESCON plant applies eco-friendly technology of nano-passivation with liquid concentrate based on complex polymers.
Such technology application allows protecting metal structures surface from environmental impact and white rust formation. When metal structures after nano-passivation are subjected to a corrosion test in a salt-spray chamber as per ISO 9227, they can stand for more than 100 hours.
The plant has developed a unique method of paint application to a galvanized surface. The equipment ensures set process parameters and allows even application of various coatings ensuring their high adhesion.
The hot dip galvanizing line includes the emissions pollutant clean-up system. Air filtration from fumes of hydrochloric acid occurs in the preliminary preparation capsule by means of a scrubber within a closed circuit. Contaminated air is supplied to the scrubber where it passes through water and is absorbed. After that the rich flushing liquid goes back to the baths of preliminary preparation. Hot dip galvanizing bath has a zinc white fume exhaust channel connected with a filtration unit by an air duct.
