Our partner, German abrasive media producer the Eisenwerk Würth GmbH, has a goal to improve the abrasive blasting with grits. Result of research on this subject is the Diamant grit.
The next-generation grit
Diamant grit has the martensitic structure. It is very sharp and one of its most important features is that is keeping that shape during the process. Thanks to that the cleaning process with the Diamant grit is faster, which allows reducing the usage of material, machines and electricity. Diamant works fine there, where other grits cannot.
The Diamant grit is mainly used in pneumatic devices with the closed abrasive circuit, like blasting cabinets and blasting chambers. it is used to remove old coatings, rust and to mat the surface of elements.
Usage
- Preparing surfaces for paiting;
- Cleaning and rust removal;
- Roughening;
- Sweeping;
- Matting.
Composition
- C 3-3,4%
- Si 0,8-1,2%
- Mn 0,8-1,0%
