Asilikos
Asilikos is a mineral expendable blasting abrasive from EP Power Grit of Oberhausen, Germany. Here you will find it in 25 kg bags in three grades: 0.2 to 0.7 mm, 0.5 to 1.6 mm and 1.0 to 2.2 mm.
Material and technical data
Asilikos is an aluminium silicate from two sources – synthetic material from boiler slag granulate and natural material from volcanic lava. The analysis runs 42 to 58 % SiO₂, 13 to 32 % Al₂O₃, 3 to 15 % Fe₂O₃, 5 to 18 % CaO and 0.5 to 4.6 % K₂O. The grain is angular, grey to black, Mohs hardness at least 7. Specific density is 2.4 to 3.0 kg/dm³, bulk density 1.05 to 1.4 kg/dm³.
Which grade for what
0.2 to 0.7 mm is the fine quality for thin-walled parts, visible surfaces and anything with a defined roughness profile. 0.5 to 1.6 mm is the all-round grade for structural steel – the one most often ordered when nothing argues against it. 1.0 to 2.2 mm is the coarse quality for heavy mill scale, tenacious old paint and concrete. Large jumps in grain size change not only the rate of work but also the roughness profile the coating has to key into.
Occupational safety and standards
For open blasting the silica content is decisive. According to its data sheet Asilikos contains no more than 1 % free crystalline silica and meets the requirements of the German DGUV rule 100-500, chapter 2.24; it is produced to ISO 11126-4 and ISO 11126-11. For the subsequent coating the salt figures matter: water-soluble chlorides below 0.001 % and conductivity below 250 µS/cm.
Bag or pallet
The 25 kg bag is the flexible size: good for trial runs, smaller sites and changing grades. But because Asilikos is expendable and blasted only once, consumption is high – in continuous use the 1,050 kg pallet is considerably cheaper per kilogram. The other grades in bags are one level up.
Alternatives in the range
If the medium is to run in a circuit instead of being blasted once, brown fused alumina or silicon carbide are the obvious alternatives – harder, dearer to buy, but usable over many cycles. For wet blasting and water jet cutting the path leads to garnet sand. The blasting media programme gives an overview of every grade.
