Printing factory installs industrial humidifier to improve the pass rate of printed matter

　　NO.1 When the weather is dry, the printing factory and packaging workshop will encounter a lot of static electricity due to low humidity, which will lead to a decrease in the qualified rate of product quality and an increase in the rejection rate. You know, paper products can easily generate static electricity through machine friction. In order to eliminate the effects of static electricity, humidifying the air is an effective way to eliminate static electricity.

　　NO.2 The printing industry can only ensure the printing quality and smooth production by providing a relatively stable temperature and humidity environment.

　　NO.3 High pressure micro-mist humidifier has been widely used in the printing industry. It is understood that in the process of production, production, processing and printing and packaging workshops, the humidity of the workshop environment is relatively constant between 55% and 65%. The humidity environment depends on the natural environment and is still difficult to achieve in the rainy season. Therefore, , 90% of printing plants will use industrial humidifiers to maintain a constant humidity environment in the workshop.

　　The role of the humidifier in the printing house:

　　1 Eliminate static electricity. Paper is prone to static electricity. Workers often experience static stickiness, especially in the dry seasons of autumn and winter. The electrostatic strength is closely related to the ambient humidity. Static electricity is more active at 30% relative humidity, and more active at lower humidity. It gradually decreases as the humidity increases, and basically disappears when the humidity exceeds 50%.

　　2 Avoid wrinkling. The reason why the paper is wrinkled is due to the phenomenon of "ruffled edge" or "tight edge", so that the paper cannot be stretched flat, and wrinkles appear during printing. This phenomenon can cause a lot of waste in the printer.

　　3 Paper dusting. The paper powder contained in the paper and the dust in the air are flying everywhere in the drying room, which has different degrees of influence on the quality of the printed matter. When the indoor humidity exceeds 50%, various dust flocs absorb water and become heavy and fall to the ground.

　　4 Prevent expansion and deformation. Due to the wide variety of paper, the expansion and contraction rates are also different. If the humidity of the paper and the environment cannot be balanced, it will cause the following conditions: the paper absorbs water to expand, lose water and shrink, so the produced paper is unqualified.
