Abrasive
Uses
​
​
Sand blasting, Polishing, Tribofinishing, Aeroscrubbing
​
Removal of residues of scale, oxide, paint, rust, varnish with or without prior chemical treatment, using a conventional blasting system.
LIGNOBLAST granulate is successfully used whenever the dimensions, geometry, and surface condition of the parts to be blasted must not be modified: its use is recommended when no alteration of the metal, or other substrate, can be tolerated, and is justified in many industries.
Industrial Applications
Petrochemicals, Aeronautics, Automotive, Marine
​
-
De-scaling of turbine blades, compressors, pistons, valves, reactors, landing gear cylinders, etc...
-
Engines for the navy: cleaning of turbochargers under load

Various uses
​
In the foundry, our products are used as fillers for the coating of molds and the making of models in resins (araldite or others).
​
-
Various LIGNOBLAST grit sizes are used for the honeycombing of abrasive wheels.
-
Cleaning of monuments or sculptures without damaging the stone and without risk for the stained-glass windows adjacent to the treatment.
-
Cosmetics: the cosmetics industry uses nutshell and apricot shell. Their use is also widespread in soaps.
-
Fillers: Walnut shell flours are used as fillers in paints, resins, pigments, glues. The granulometry of the media varies according to the use, from granules to very fine flours.
-
Pets: Pellets are a natural, safe, and biodegradable litter for birds, reptiles, and small animals. Pellets are dust-free and easy to use.
-
Oil industry: crushed walnut shells are used in drilling mud in three qualities: coarse, medium, and fine.
Main Implementation Techniques
Sandblasting and Satin-Finishing
LIGNOBLAST granules are commonly used to sandblast metals, glass fibers, plastics and stones using a conventional sandblasting machine (hardness on the MOHS scale: 3.5).
​
Tribofinishing - Tumbling​
On rotating or vibrating drum in possible association with other products which intervene for a complementary action to the abrasivity of the LIGNOBLAST media. Small metal or alloy parts are often treated by this process.
