Sandblasting

Surfaceces cleaning and preparation is a crucial step for the success of the coating to be performed later. It can be of various types: liquid, powdered, hot-rolled.

One of the most high-performance and multi-purpose types of preparation is sandblasting. It consists of an abrasive jet using compressed air. The mechanical action guarantees optimum cleaning that can be more or less pushed depending on the surface to be cleaned .

Typical treated surfaces: carbon steel, stainless steel, steel alloys, aluminum, marble, wood etc. executable according to the final result obtainable with different types of methods and abrasives, such as:

Standard sandblasting

Treated surfaces: carbon steel, stainless steel, steel alloys, aluminum, marble, wood etc. With this type of preparation it is possible to obtain different degrees of cleanliness on various surfaces which can be bodywork parts, agricultural vehicles and equipment, metal structures, machinery and industrial structures, facades of civil construction, fences etc. The preparations described can be performed in factory or on site with the use of the mobile sandblasting units and the necessary equipment to contain dusty emissions.

Sandblasting with natural mineral abrasives (garnet, quartz, corundum, olivine)

Special sandblasting

Sandblasting with glass microspheres

Ideal for cleaning and polishing surfaces that should not be painted such as stainless steel, aluminum, copper and other soft surfaces on which the glass exerts an extremely delicate cleaning action without creating any type of incision or porosity giving the surface a uniform and satin appearance.

Sandblasting with ARMEX system

This system uses sodium bicarbonate as a cleaning substance which, being completely non-toxic, lends itself to various applications where a very low environmental impact is required. Furthermore the cleaning of the surfaces takes place by chemical and not by mechanical effect, without the slightest incision of the surfaces. Therefore it is usable for delicate materials like glass, facades of civil constructions, historical works, monuments etc. It is also indicated for removing graffiti and and dirt caused by the smog.

Painting

After adequate surface preparation it is essential to apply a correct painting cycle according to the environment in which the painted surfaces must operate and according to the operating conditions. Here below a generic list of the cycles that can be performed and their characteristics.

Standard painting

Synthetic painting cycles

Suitable for surfaces exposed in rural environments.

All cycles can be subject to maintenance and can be carried out in the factory and / or on site with mixed air (b.p) or airless (a.p) spray systems

Speciali painting

Painting cycles by immersion in sea water

Suitable for surfaces in contact with sea water, even in continuous immersion or areas of shore.

Thermosetting phenolic painting cycles

Coating with high anti-corrosion resistance to acids in constant immersion and with temperatures up to 220 ° C after baking the treated equipment in the oven. Optimal painting cycle for the internal protection of the heat exchangers tube bundles, with application carried out in high pressure with a semi-automatic machine with a range of use for internal tubes with minimum diameter of 19.5 mm (3/4 ”) and maximum from 100 mm (4 ") with length up to 14 mt.

Thermoinsulating painting cycles

Heat-insulating coating up to 150 ° C, also suitable as a safety coating in areas where the system is trafficked by operators. It contains and retains process temperatures with considerable advantages compared to traditional coimbentation (laminates and rock wool), among all the advantage of having the treated surfaces in view, the non-formation of undercooling corrosions and the ease of maintenance restoration with further applications in the time. It also prevents the temperature variations of the fluid contained in the equipment treated, completely eliminating the phenomenon of solar radiation.

Chemo-tacking painting cycles

Acid-sensitive coating with a net color change in the event of contamination, specific for applications located in connection areas of equipment (flanges, valves, plugs) where it is necessary to visually monitor any even minor spills of the fluids contained.

Thermo-varnishing painting cycles

473/5000 Temperature sensitive coating with a net color change in case of raising of the same, specific for equipment applications where it is necessary to visually monitor any anomalous increases in internal temperatures. • Priming at 210 ° C • Irreversible color change from green to blue at 240 ° C approximately 30 minutes • Trigger new color change at 320 ° C • Irreversible color change from blue to light gray at 350 ° C in about 45 minutes

COOKING COATS WITH ARC THERMAL SPRAY SPRAYING SYSTEM

Coating performed with electric arc fusion and projection of the molten metal onto the adequately prepared surfaces. The coatings that can be obtained are suitable for various application functions to increase the strength and durability of the treated surfaces, with excellent properties depending on the alloys referred to, which can be zinc, aluminum, hastalloy C, stainless steel, inconel, copper, brass, and many others superalloys that according to their choice give the support the following qualities: • High anticorrosive power • High temperature resistance • High anti-wear power
