Method for manufacturing paints and inks,and product produced thereby
Abstract
Abstract THE APPARATUS INCLUDES A STORAGE TANK FOR SOLVENTS, A BALL MILL, AND A TINTING TANK. CARBON DIOXIDE SUPPLY LINES ARE CONNECTED TO EACH OF THESE. ADDITION OF CARBON DIOXIDE UNDER PRESSURE TO THE STORAGE TANK PRECARBONATES THE ORGANIC SOLVENT AND PROVIDES A CARBONATED PRODUCT WHEN MILLED WITH A PIGMENT. THE CARBON DIOXIDE CAN BE ADDED AT THE MILL EITHER ALONE, OR IN COMBINATION WITH PRECARBONATION. SOLVENTS OR DILUENTS ARE ADDED IN THE TINTING TANK AND THE RESULTING PRODUCT IS A CARBONATED PAINT OR INK WHICH HAS IMPROVED ANTI-SKINNING CARACTERISTICS. THE STORAGE TANK ARRANGEMENT REDUCES EMISSIONS OF ORGANIC SOLVENTS INTO THE ATMOSPHERE. THE USE OF CARBON DIOXIDE REDUCES FLAMMABILITY IN THE SYSTEM, OF THE PRODUCT, AND DURING SUBSEQUENT USE. IMPROVED CONDUCTIVITY OF THE CARBONATED SOLVENT ALSO RESULTS.
