Supplied by Standard Industrial Systems and manufactured by Idea Machine of Finland, the application demanded cleanliness of the highest order before processing in a new
state-of-the art coating installation.
Cleanliness of the washed samples is gauged by measuring the contact angle formed on the glass surface by a sample of pure water injected upon it.
The complex process includes the use of a high quality pure water (1mS/cm) throughout the various stages beginning with an alkaline (Ecospray 5275) followed by an intermediate rinse. A further acid wash is followed by successive rinses and a hot drying facility, all stages being completed within a single chamber without operator intervention after the initial loading. Cross contamination of the various stage fluids has been eliminated by a unique process of counter refills and the continuous automatic dosing of the selected chemical constituents. Both acid and alkaline fluids are combined to form a neutral fluid for disposal, again achieved in-process without operator involvement.
