Tipping paper material  printing

The so-called thick coatings (also known as pigment paste), mainly prepared with the following materials: calcium carbonate, titanium dioxide, iron oxide red, yellow iron oxide, polyvinyl butyral plastic, ethanol solvent. Put them in the process recipe and a certain order of feeding, stirring equipped with powerful turbine

Barrel sufficiently stirred and mixed uniformly. Then into the grinding machine. Machine steel barrel of a sandwich, during which cold water for cooling. Weigh a certain amount of boron glass beads as the grinding media. Power grinding machine is 10kw, speed of 1460r / min. Operated in series with two grinders, milling is completed after 100 to 150 mesh sieve, and the resulting paste storage backup.

Printing plate material is copper (or copper alloy), adopt electronic scanning carving, drawn according to tipping paper pattern requirements. After carving the plate, but also on the surface coated with a layer of chromium, its purpose is to protect the plate, prevent wear, extending its life.

When printing tipping paper, the first paper roll through the guide roller rolls delivered to the printing office, printing paste in the coating pan is rotated, the excess paint scraper scraped the plate clean. To give the plate between the print roller and some pressure on the paper between the two evenly and smoothly through, the paint on the plate quickly satisfactorily transferred onto the paper. Then into the drying unit, which completed its first printing. After drying the paper, and then a second printing, adding to the pattern prints, the same way. Finally, in accordance with the requirements of the order, and strictly carry out the cutting, the whole election, packaging, warehousing.

Such a simple piece of paper, it is not a simple process. As long as there is a process which is a problem, not a waste occurs, it is to reduce production.
