NETTOYAGE CRYOGÉNIQUE LATEX : PINCES
Découvrez dans cet article et cette vidéo l'opération de nettoyage cryogénique latex sur pinces servant à la fabrication du film étirable alimentaire. The equipment used is the ATX25-E. This article and video are taken from the section applications du nettoyage cryogénique.
Dry ice blasting on food stretch film manufacturing process
- Industry : packaging manufacturing
- Treatment purpose : Latex residue on clamps
- Equipment used : ATX25-E
Using dry ice blasting to restore the food stretch film manufacturing process offers numerous advantages, including:
- A respectful of the treated surfaces of treated surfaces. Dry ice has the hardness of chalk and is therefore not abrasive.
- A dry process : dry ice is actually carbon dioxide in solid form
Comment fonctionne le procédé de nettoyage cryogénique pour le retrait des résidus de latex ?
The dry ice is introduced into the Cryoblaster ATX2-E model in this video. This dry ice comes in the form of pellets or mini-cylinders with a diameter of 3 mm.
After connecting the ATX25-E to the power outlet (220 V), and to the compressed air network (6 bars), the dry ice is then projected onto the surfaces to be cleaned at very high speed through a blast hose, spray nozzle and gun, in the manner of sandblasting, without its drawbacks.
The effectiveness of the process relies on the interaction of 3 phenomena:
- Thekinetic energy which the dry ice pellets carry, creates micro-fissuring of the dirt upon impact: this is called mechanical shock.
- Since the temperature of dry ice is –78.4°C, this creates a thermal shock or a temperature differential between the substrate and the dirt. The dirt then shrinks and detaches from the surface.
- Finally, the transition of dry ice from solid to gaseous state instantly removes the dirt. This is called sublimation.
