THE DRY SPRAY TECHNIQUE
The partner BERTHIER ETUDES, through its Business Unit ECOTREAT, presents a surface functionlization to transform any mtallic surface into a antiadhesive and abrasion resistant surface.
This process is ecological as it is a wet process avoiding the use of contaminant liquids and with low energy consumption.
THE CONCEPT
The process that is being used to obtain this surface functionalisation consists in :
A high velocity projection of antiadhesive mixed with an abrasive product.
The polishing of the surface for a few seconds with a very smooth equipment
The passage of the surface into the oven at a temperature of 250 to 300 °C for 30 mins.
During the projection, the abrasive product creates crevices in the substrate. The crevices are filled by the anti adhesive product.Very few abrasive remains on the treated surface.
The thermic treatment sticks the anti adhesive product on the substrate creating the better resistance to abrasion.
This process can easily be robotized to treat equipment in large series.
