Wet cardboard

Cardboard water produced from cardboard production line is too high

the reason

Insufficient heat on the hot plate of the double-sided machine. The temperature of the steam pipe is too low. Excessive gluing on the single-sided machine and the paste-gluer. Excessive eccentric rotation of the paste roller and the metering roller. The gap of the metering roller is not parallel.
Adhesive roller or metering roller wear, or bearing wear Metering roller Scraper wear or misalignment Adhesive on the presser roller Pressure on the nip is too high Velocity ratio between the single-sided web and the rubber roller is inaccurate Paste solid content is too low High or low viscosity corrugating roller wear

Measure

Increase heat or heat transfer in hot plate Slow down the machine Check boiler pressure, steam trap, and bypass valve Check the condition of the paste roller and metering roller, check if the gauge roller gap is parallel, and if necessary, reverse the roller. Reducing the amount of glue after corrective measures are completed Check the scraper, adjust or replace Reduce the pressure of the platen roller.
Check the speed ratio and, if necessary, adjust the speed of the upper roller. Increase the solids content in the paste formulation. Check the viscosity of the paste and adjust if necessary. Check the condition of the corrugating roller. If necessary, replace the corrugating roller.
