Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic paint recovery, in particular to an electrophoretic paint recovery device for electrophoretic coating. Background Art

[0002] The ultrafiltration technology for electrophoretic paint recovery is to selectively separate substances through the microporous structure of the membrane surface. When the liquid mixture flows through the membrane surface under a certain pressure, small molecular solutes pass through the membrane (called ultrafiltrate), while large molecular substances are retained, so that the concentration of large molecules in the original solution gradually increases (called concentrated solution), thereby achieving the purpose of separation, concentration and purification of large and small molecules. The electrophoretic paint is filtered through the ultrafiltration membrane, the polymer resin molecules and color paste are retained, and the water and small molecular substances pass through the separation membrane, thereby achieving the effect of purifying the electrophoretic paint and removing water. The existing electrophoretic paint raw material recovery device does not have the function of cooling, causing the raw materials in the storage tank to volatilize too quickly, shortening the service life, and after cooling, the raw materials will form particles, which will cause the granular impurities contained in the electrophoretic paint for the next use, resulting in poor effect after electrophoretic paint coating. For this reason, we propose an electrophoretic paint recovery device for electrophoretic coating. Utility Model Content
