It is known that in the process of intaglio printing, the imprint roller contacts and separates from the paper, the paper contacts and separates from the printing plate cylinder, the printing plate cylinder rotates at high speed in the ink, the ink flows in the ink tank, and the doctor blade scratches and squeezes on the printing plate cylinder, all of which will generate static electricity
Electrostatic hazards are great and multifaceted, especially in intaglio printing. To prevent the harm and property damage caused by static electricity fires, the usual measures taken are to use ZS-120Z printing workshop humidifiers and ZS series intelligent ultrasonic industrial humidifiers to increase workshop humidity, increase air circulation, increase fire extinguishing equipment, and install static electricity elimination devices
The gravure printing machine workshop is equipped with humidification pipelines, which are arranged side by side on the top of the factory building; The humidification pipeline is provided with spray holes at intervals; Controlled by an intelligent humidity controller, the original humidification system in the workshop used tap water for humidification. Due to the large amount of calcium and impurities in tap water, the atomization device of industrial humidifiers often becomes blocked, resulting in uneven humidification and inaccurate humidity control in the workshop
Improvement method: The condensed water generated from the steam return water used in the gravure printing machine drying device is used as water for industrial humidifiers, and a filter is added to effectively ensure the atomization effect of the normal working process of the industrial humidifier nozzle, effectively improving the accuracy and stability of air humidity control, and achieving water resource recycling
Adjust the air humidity of the gravure printing machine workshop before the equipment runs. Adjust the air humidity of the gravure printing machine workshop to about 55% RH by using the ZS-120Z printing workshop humidifier and the ZS series intelligent ultrasonic industrial humidifier. As the water content in the air increases, the static electricity on the paper surface will be quickly released into the atmosphere, reducing the amount of static electricity carried by the paper, thus reducing the amount of static electricity carried by the paper when the equipment runs at a low speed, Fire caused by dry air and static electricity on paper
The solution to the electrostatic problem in the gravure printing machine workshop mainly starts from ventilation, humidity adjustment, delayed start of electrostatic ink suction, and delayed release action. Measures have been taken to effectively control the electrostatic fire problem in the gravure printing machine's electrostatic ink suction system, solve the problem of electrostatic fire from the source, eliminate fire hazards, ensure production safety, and maintain social stability, Improved the economic efficiency of the enterprise
