Electrolytic Galvanising and manganese Phosphatising   Rivestcor PLUSES for for electrolytic Galvanising and manganese Phosphatising. Large-sized tubs (length: 6.000 mm, depth: 2.000 mm) Production capacity of 9.000 ton/year for galvanising and 630 ton/year for phosphatising.   Main application fields develop where it is necessary to avoid corrosion and reduce maintenance operations, for example: a number of elements of ski-lifts; reticular structures such as trusses or tubes exposed to adverse weather conditions or subject to the action of mineral or marine salts; in the building industry for the treatment of fencing, gates, window grates or shutters. Yellow electrolytic galvanising as well as manganese phosphatising is particularly suitable for the pins of mechanical earth movers or to prevent the corrosion of weapons' metallic parts, and mechanic small parts in general. Besides preserving the physical characteristics of the pieces, without altering their mechanical capacities, these treatments confer them a pleasant appearance.   OUR WINDOW Galvanisation scaffolding bars to 6.50 meters long We realized by making use of the diagonal of our tanks, galvanizing the scaffolds of bars for 6.50 meters long! Manganese Phosphatising Phosphatising process mainly consists in immerging the already cleaned material into a hot phosphatic solution of manganese salts (85°-90°C), after activation in solution containing grain refining agent. After drying with warm air in oven, the material is impregnated with protective oil and then conditioned. Anticorrosive surface treatment The material is first of all cleaned independently whether it must be galvanised or phosphatised. Electrolytic galvanising The galvanising process takes place in tanks containing a soda-alkaline solution at 120g/l, dissolved zinc at about 8g/l and commercial additives Primion 240 by Coventya, for electrochemical reduction caused by the cathodic polarization of the material in electrical contact with a c.c. rectifier; the electrochemical cell part is composed of carbon steel plates placed sideways on the material.
