1.The principle of coating machine scraper system:
The principle of blade coating is relatively simple, that is, through the roller on the excess coating will be coated on the paper, and then scraping the excess paint with a scraper. Generally according to the type of coating machine, it is divided into several types, such as dragging blade coating, inverted blade coating, flexible blade coating, Bill blade coating, double flow blade coating and jet type blade coating.
1, after coating can be smooth without defects of the coating. As the blade coating with the base paper surface of the depression of the coating is filled with the characteristics of non-conformal coating, so the coating surface is very smooth, with good printing results. Generally, its smoothness is more than 200 seconds, gloss 40 ~ 60%.
2, coating machine scraper system for high-concentration coating and high-speed paper machine coating. Therefore, the blade coating is currently the fastest growing, the most widely used coating form.
3, the device structure is compact, dry load is small. As the coating of the blade coating of solid content is generally about 60 ~ 62%, so the load of small drying, small steam consumption, in order to improve the speed of the paper machine provides the conditions. And, after practice has proved that the higher the speed, coating quality is better, the more detailed the surface, the higher the economic value.
4, there is no rotation of the roller, it will not produce splashes of paint to improve the workshop environment.
