With the water-sand blasting process, an abrasive agent is added to the high-pressure water, in order to enable efficient paint and rust removal from metallic surfaces. Dust contamination concerns mean that pure sand blasting is prohibited in many countries, or permissible only under strict conditions. Water-sand blasting is an alternative which enables the use of abrasive agents, such as sand, silica sand or ground blast furnace slag, in order to achieve different shot blasting results.
In comparison with purely abrasive agent shot blasting systems, this system has the advantage that no deformation (peening) arises in the shot blasted material. With the water-sand blasting process the heat is removed by the water so no form-changing heat concentration occurs in the shot blasted material. In addition, in case of paint removal with high pressure, the removed material is carried in the water and washed away.
In case of the water-sand blasting process, our AK600 HIGH Pressure Gun is provided with an injector, through which the abrasive additive is added to the water. With increasing operating pressure, the required quantity of abrasive agent reduces. Vice versa in comparison with pure water jets, a significantly lower pressure is required for a comparable result.
