Static electricity on printed paper is one of the common problems in the printing process, which can cause the paper to stick, absorb dust and paper scraps, and affect the printing quality. To solve this problem, many printing shops have started using printing paper humidifiers. This article will cover the causes of static electricity on printed paper and how to use a humidifier to solve this problem.
First of all, let's understand the reasons why printed paper has static electricity. Static electricity is caused by an imbalance in the charge of the paper due to the friction of the paper against other objects during the printing process. This charge imbalance causes static electricity to mount the paper, which in turn absorbs surrounding dust and paper scraps. This will not only affect the quality of the print, but can also lead to the failure of the printing press.
To solve this problem, many printing shops have started using printing paper humidifiers. A humidifier can increase the humidity of the paper, thereby reducing the phenomenon of static electricity in the paper. When the paper is in the proper humidity range, static electricity is neutralized, reducing the likelihood of the paper absorbing dust and paper scraps.
The method of using a printed paper humidifier is simple. First, place the humidifier near the press to ensure that it distributes moisture evenly to the paper. Then, adjust the humidity controller of the humidifier so that the humidity of the paper is kept within the proper range. Typically, the humidity of the paper should be between 40% and 60%.
In addition, there are other measures that can be taken to reduce the problem of static electricity on printed paper. For example, a static eliminator can be installed on the conveyor belt of a printing press, which can effectively neutralize static electricity on the paper. In addition, the press and paper transfer system are cleaned regularly to prevent the accumulation of dust and paper scraps.
In conclusion, static electricity on printed paper is a common problem in the printing process, but this problem can be effectively solved by using a humidifier on printed paper. The humidifier can increase the humidity of the paper and reduce the phenomenon of static electricity on the paper, thereby improving the printing quality. In addition to using a humidifier, there are other things you can do to reduce the occurrence of static electricity problems. It is hoped that this article will provide readers with solutions to electrostatic electricity on printed paper and arouse readers' interest in printing technology.
