What is the main role of varnish on the surface of the iron box
After the tin box has been printed, the next step is to apply varnish or matt oil to the surface of the iron box, or some special oil. So why do you want to polish the surface? What is the main role of these varnishes?
1. Increase the brightness of the iron box. On the printing iron surface, a layer of bright oil is also needed to increase the gloss of the surface of the printed product, and the hardness of the surface of the product can be improved, so that the printing ink layer has certain flexibility and corrosion resistance. The varnish used for tinplate should have the following properties: (1) Good color retention. The thinner in the varnish can not make the ink bleed and fade; (2) It has sufficient hardness and firmness to withstand the deformation process of the post-process; (3) It matches the white paint or the base oil, and does not corrode White paint or base oil, commonly used printing iron varnish with polyester, modified epoxy ester and acrylic resin. According to different product characteristics, in addition to bright oil, there are also matt oil, wrinkle varnish, and pearl filling style. , unique art and foreign trademark products.
2. When painting and printing, it is indispensable that both the coating and the ink need to be dried in a tunnel oven. The drying conditions of the iron ink are usually from 130 ° C to 160 °. Between C, the time is controlled in about 10 minutes, the drying strip of the paint f'~ 170 ° C ~ 210 ° C between the tunnel oven is about 30 meters long. It consists of 3 steps, namely the warming zone and the cooling zone. The temperature rise is the first stage after the tinplate enters the oven. The main function is to raise the tinplate from room temperature to the set temperature. The main function of the constant temperature zone is to maintain the temperature reached by the heating zone. The function of the cooling zone is to fully cool the dried tinplate printing. Once the cooling is not enough, the paint film is easily scratched by each other when the tinplate is stacked, and the stacking fork is prone to sticking phenomenon and baking time and machine speed. Relatedly, if the speed is too fast, the entire drying time will be shortened, and the coating ink is insufficiently baked during the peak temperature time, resulting in a tender film caused by the ink and the coating being dry and impervious. Eventually, the phenomenon that the food or beverage becomes odor after contact with it occurs. If the machine is too slow. It will cause excessive baking. In this case, many coatings become brittle and prone to paint stripping or varnishing. At the same time, excessive baking can also cause discoloration of the coating ink. The measure to avoid poor baking is to periodically check the graph of the oven's temperature controller to ensure the peak temperature time at standard time.
