How to prevent particles from appearing in electrophoresis?

Electrophoretic coating processing is a new technology on the basis of traditional coating. It can not only achieve better coating effects, but also is environmentally friendly and will not harm the environment. However, it should be noted that before the electrophoretic coating process, the electrophoresis bath should be checked for sediment or agglomerates to prevent the occurrence of particles and bumps and improve the quality of the coating.

Speaking of particles and bumps during electrophoretic coating, after drying, there will be a series of rough or hard particles visible on the surface of the electrophoretic coating film. Phenomenon. This phenomenon occurs because, to a large extent, it is actually because there are sediments or agglomerates in the electrophoresis tank, as well as poor filtration on other foreign matter tanks.

After electrophoretic coating, if the flushing fluid is dirty or the flushing water contains too high paint concentration, in this case, particles or lumps will appear, and the drying furnace will be dirty. On a series of granular dirt. As for the coated objects that have entered the electrophoresis tank and the spreader is not clean and phosphated, the water is not clean. What follows is actually because the coating environment is dirty.

Particles and bumps during electrophoretic coating can actually be prevented. In this regard, filter in the enhanced electrophoresis tank. All circulating tanks should pass through the filtering device. At this time, we can actually recommend a 25-precision filter bag to filter and strengthen the stirring to prevent precipitation and eliminate the "dead corners" in the tank and the pH value of the exposed metal areas and its alkaline substances.

For the prevention of particles and lumps during electrophoretic coating, we actually need to pay attention to directly improve the cleanliness of the rinse water itself, and try to reduce the solid content in the rinse water after electrophoresis to control The production of bubbles.
