Not even the best, the most expensive paint or coating can provide appropriate protection against corrosion if it also causes damage from under the coating, from the inside. The proper surface preparation is at least as important as the coating itself.
A technology that uses quartz-sand grains mixed with compressed air for the cleaning and treatment of different surfaces. As opposed to other cleaning procedures, sandblasting not only removes the different contamination, remains of materials or paint from the given surface but it also slightly abrases the surface by removing its top layer. The process can be used for forming rustic surfaces and also for removing paint or graffiti depending on the type of surface. Sand(grain)blasting can remove oxidation, rust, scale, old paint or coating and varnish from almost any surface.
The resulting new, clean to metal surface is a perfect base for further treatment: polishing, powder-spraying, galvanizing, etc. As opposed to chemical processes the advantage of sandblasting is that there are no remaining chemical materials that would have a negative effect on the later coating. By using the power of the high-pressure water the result is a well-adhering and rough surface.
The procedure is the same as with sandblasting but it is performed with the type of grain most appropriate for the surface and the task. Its outside application can only be efficient and economical in case of special tasks. As for most surfaces sandblasting with normal quartz-sand can provide the expected result.
This procedure is similar to high-pressure washing. The emitted high-pressure water is mixed with grains of sand, thus enhancing the cleaning effect. Its advantage is that is does not result in dust formation. A number of materials can be applied as cleaning grains. The material of the grain significantly influences the speed of the cleaning and the quality of the work. For cleaning metal surfaces, mainly the following materials are used:
This procedure works similarly to a simple, small household washing appliance with which you can wash the car or clean the pool in the garden. The only thing the machine needs is tap drinking water. The machine increases the water pressure up to 2800 bar with the help of a high-volume ceramic piston compressor. Then the high-speed water, which is hot due to the pressure, leaves through the nozzles on the end of the special hose and removes all kinds of contamination and old coating from the target surface. The equipment can be used effectively not only on metal surfaces but also on concrete, ornamental stone, marble and other hard surfaces.
We have specialised in the surface protection of steel structures and the formation of – both normal and heavy duty – coating systems on the inner surface of tanks. Wet sandblasting technology is also available, where excessive dust formation is to be avoided. However, we have performed the complete surface protection of several vans, trucks (even together with the cabin), buses, farm engines and trailers.
Among the jobs we have completed the formation of the external- and internal coating systems of horizontal and vertical fuel and methanol tanks of MOL Rt. occupies an important place.
