Method for controlling deposit of coating material in electrostatic coating
Abstract
Abstract A METHOD FOR CONTROLLING THE DEPOSITION OF AN ELECTROSTATIC COATING MATERIAL IS DISCLOSED. ACCORDING TO THE METHOD, A MIST OF COATING MATERIAL IS FIRST FORMED IN A MIST GENERATOR. THE MIST IS THEN CARRIED BY AN AIR STREAM TO A DELIVERY EQUALIZER THROUGH WHICH THE MIST IS UNIFORMLY SUPPLIED TO A MIST CONTAINER. THE AIR STREAM SUBSEQUENTLY CARRIES THE MIST FROM THE MIST CONTAINER TO AN ELECTROSTATIC CHARGING ZONE WHEREIN THE MIST RECEIVES AN ELECTROSTATIC CHARGE. FINALLY, THE CHARGED MIST IS SUPPLIED TO AN ELECTROSTATIC DEPOSITION ZONE AND IS DEPOSITED ON A CONTINUOUSLY RUNNING SHEET. THE QUANTITY OF COATING MIST IS CONTROLLED BY ADJUSTING BOTH THE AIR-FLOW FOR CARRYING THE MIST AND CONTROLLING THE POTENTIAL IN THE ELECTROSTATIC CHARGING ZONE IN RESPONSE TO THE VARIATIONS IN THE SPEED OF THE CONTINUOUS SHEET.
