Abstract:
A method, and components therefore for cleaning and reclaiming silk screens and the like. The method involves the steps, in general, of handspraying silk screens to be cleaned at a nominal water pressure of 3,000 psi plus or minus 300 psi, and this preferably at a water temperature of from 70 to 140 degrees Fahrenheit. The water circulating system is preferably a closed system that is periodically automatically replenished as needed. This saves a volume of water required, and such water is reclaimed by filtering systems. The filtering structure employed comprises a series of classifier screens of progressively reduced mesh and disposed in mutually superposed position. A further filter is in the form of a disposable bag filter made of paper or other suitable material preferably having a pore size of the order of ten microns. Additional filters are employed as needed. The spray cabinet employed has silk screen support bars and clamping means for clamping the screens in sloping condition.
