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.
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
Cleaning of airport beacons without damaging the optics
Stripping of fiberglass boat hulls
LIGNOBLAST 4/6, 3/6, 6/12 granules are suitable for delicate parts supporting electronic components.
Deburring of objects made of thermosetting material
Satin-finishing of thermoplastic parts
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.
