Protection against corrosion, the effects of use and weathering is of primary importance for the preservation of the structure. There are a number of solutions available, but these can only be applied effectively and durably to completely clean surfaces.
Processes such as electroplating, sintering, painting or varnishing can only be used effectively if the surface is sufficiently clean before the required treatment.
One of the most professional ways to achieve this is to use our years of experience in granularity.
Not sand?
The granulation process was patented in the 19th century and because surface treatment was done with sand for a very long time, it was colloquially known as sandblasting.
Many people still use sand in this way, but in fact, as technology has developed, sand has become Spreadsheet have been completely removed from the process and replaced by steel, corundum, glass, ceramics or dry ice.
Of all the spreading agents listed, corundum is perhaps the least familiar. But everyone has probably heard of the natural versions, which are discoloured by contaminants. If it is red, it is called ruby; if it is any other colour, it is called sapphire. In grain milling, a variety of this mineral, called brown corundum, is artificially produced from bauxite in an electric furnace at 3000°C. It is considered to be an extremely stable and hard material, which makes it perfect for this task.
The process of granulation is very simple. High-pressure compressed air is used to propel the spray particles at high speed onto the surface to be cleaned.
The impact of the „bombardment” the cleaning particles abrade the top layer of the surface corrosion and other contaminants. The resulting metal-clean surface is now ready for further treatment.
Surface cleaning: with what?
In addition to the name, another common misconception is that grit blasting can only be used on the outer surface of metals. However, thanks to the continuous development of the technology and the wide range of spray materials, wood, plexiglass, stone and glass surfaces can all be cleaned by this method. The spray material and the particle size to be used to achieve a perfect abrasion of the external surface is always determined by the surface to be treated.
The results in a rough - SA 2.5-3 grade - surface free from dirt and corrosion, which, after cleaning, can be easily Available at with primer, varnish or even powder coating.
