We realized by making use of the diagonal of our tanks, galvanizing the scaffolds of bars for 6,30 meters long!
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.
The material is first of all cleaned independently whether it must be galvanised or phosphatised.
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.
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.
The capacities of our Human Resources and the cooperation with Ing. A. Laidani, who put at our disposal his consolidated experience in this field, allow us to deliver consulting services which go beyond the mere surface treatment.
Each piece under treatment is subject to a customized and optimized working cycle, in order to obtain the best in terms of quality while reducing the costs.
The consolidated capacities of our technicians are integrated and supported by efficient analysis equipment and by an adequately equipped internal laboratory.
The plant for the recovery and regeneration of vector fluids and mixtures for a perfect electrolysis, are very powerful and reliable and allow fast production times and environment protection in compliance with the more recent regulations in force on reduction of pollutants.
