Corrugated cardboard production line
Adhesive index
The viscosity and solid content of the adhesive for corrugated board should be adjusted according to the season. Usually, at low temperature and low humidity (winter), the viscosity of the adhesive for single-corrugated cardboard is 17-21s (coating 4 cups, the same below), and the solid content is 17%-19%; the viscosity of the adhesive for three-corrugated cardboard is 40- 60s, the solid content is 18% to 20%. In high temperature and high humidity (summer), the viscosity of the adhesive for single corrugated cardboard is 20-25s, and the solid content is 19%-22%; the viscosity of the adhesive for three-corrugated cardboard is 55-90s, and the solid content is 21%-25%. %. In addition, it should be ensured that the adhesive sticking length (dip a little adhesive on the thumb, bond with the index finger, slowly pull the two fingers apart to the distance between the two fingers when the adhesive breaks) is 15-20mm.
