I don't know why imported UV printers will often be cut off in Bai Mo soon after I buy them.

Dear, I'm glad to see your question. It's been a long time. I wonder if you are still engaged in this field. Now I am also working in a printing processing factory. As you said, the ink of the nozzle will be cut off because: the composition of Bai Mo is mainly titanium dioxide. Titanium dioxide and correction fluid are the same, which has a covering effect, but titanium dioxide has a large proportion, is insoluble in water, and is easily blocked when the machine stops. There will be precipitation (titanium dioxide, molecular formula is TiO2, which is insoluble in water), and there is no way to make it soluble in water. The best way is to use titanium dioxide with small particles as much as possible, so that it can form a suspension with water, which is slightly better. Therefore, suspending agents are added to the ink now to make it suspend and avoid precipitation. Under working conditions, the ink in the ink tube will not precipitate immediately, but it will still precipitate in the ink tube as long as it stays for a long time. When the nozzle uses the precipitated ink, the printing effect will become worse, and the nozzle will be slowly blocked for a long time. So now our company uses a printing machine named plante Printing Equipment Company, and their family has a patent "Bai Mo Circulation System" to solve the problem that the nozzle is blocked and ink is broken. These are all from them.
