Grit blasting is the most suitable and fastest process for mechanical cleaning, recleaning and preparation of contaminated, corroded metal surfaces prior to surface treatment.
The durability of metal surfaces, corrosion protection of different surface treatment processeskal (for example, by painting, sintering or galvanising). However, these processes are only really effective if the treated surface is completely clean. The metallic cleanliness essential for a good quality surface finish is best achieved by grit blasting.
The technology of granulation
Grit blasting is the most suitable and fastest process for mechanical cleaning, recleaning and preparation of contaminated, corroded metal surfaces prior to surface treatment.
In the process of granulation high pressure compressed air made of different materials, deliver fine particles to the workpieces to be cleaned. The high-energy particles are removed by friction, abrade the surface layer of the material to be cleaned, making it metal clean.
In the past, the material used for granulation was almost always sand, so the process also widely known as sandblasting.
The procedure Benjamin Chew Tilghman patented on 18 October 1870. Technological developments and the growing importance of environmental protection a wide range of materials for granulation is available, both in variety and grain size. Besides corundum and steel grit, crushed glass, ceramics and dry ice are the most common grit used.
The quality and quantity of the grit material is always determined by the surface to be treated and its material, as different grit materials and their varying particle sizes have different abrasive effects on the sprayed surface.
The advantages of granular spray
- The granulation on almost any surface applicable. In addition to metals, stone and brick, wood, ceramics, glass and Plexiglas surfaces can also be cleaned using this method.
- The granulation forms surface roughness on cleaned materials, which has excellent adhesion, so that the cleaned material can be easily handled afterwards.
- The granulation process achieves a surface quality of SA 2.5-3, on which in addition to standard primers and topcoats, a high quality powder coating can be applied.
