Title: Method for overspray recycling during the use of paints based on water-soluble binders in industrial spraypainting plants
Inventor: DAIMER WOLFGANG DIPL ING
IPC: C02F1/461
Filed: 1991-02-07
Granted: 1996-01-25
Abstract: The invention relates to a method for the continuous precipitation and recovery of water-dilutable paint materials from the circulating water of spray booths by electro-precipitation in a direct-current circuit. The continuously precipitated and discharged paint materials, consisting of binder components, pigments and, if appropriate, auxiliary solvents, may, after being recombined with the neutralizing agent precipitated on the counter- electrode, be returned to the painting process again, whilst the purified circulating water is led back into the spray booth in a closed circuit. The advantages of the method are the possibility of full utilization of the overspray which unavoidably occurs, the avoidance of the hitherto customary coagulation of the overspray by means of precipitated chemicals and the associated problem of the disposal of non-utilizable paint sludge as well as the avoidance of waste water pollution due to the disposal of waste water from spray booths.
