Heidelberg 102F five-color machine alcohol fountain solution preparation

I plant in 1993 introduced the 102P type outside the five-color Heidelberg offset press, specifications for the 102cm × 72cm. This type of machine dampening system is equipped with automatic temperature adjustment, automatic adjustment and addition of alcohol fountain solution concentration. In the third year of use of this offset press, the dampening system cannot automatically adjust and add water, alcohol, and fountain liquids. The plane was inspected and repaired by the Beijing Baolong Foreign Bank. It was believed that the detection of the two probe rods of alcohol and water dying fluid was damaged and required replacement of new parts, which was very costly. In order to reduce expenses, after further analysis, I found out how to formulate alcohol fountain solution. The preparation method is introduced as follows for reference by colleagues:
1. Calculate the bottom area of ​​the alcohol fountain solution. The length (l), width (b) or bottom radius (r) of the container can be measured according to the shape of the container. The bottom area of ​​the container is calculated from S=lb or S=πr2.
2. Water is added to the container and the height (h) of the water added to the container is measured. This gives the volume of water added in the container, V = Sh.
3. Depending on the volume of water added to the vessel, water was added to the water in a ratio of 100:1 water:brute liquid.
4. According to job printing requirements, determine the optimal concentration of alcohol in aqueous solution. Calculate the volume of alcohol to be added by formula concentration = volume of alcohol / volume of water + volume of water hopper, and then add this volume of alcohol. In this way, we got the concentration of alcohol fountain solution. The method for preparing the alcohol fountain solution is simple and convenient, and the concentration of the alcohol fountain solution is controlled accurately, which provides the prerequisite for the operator to grasp the ink and ink balance during the printing process.
