The solid content of the adhesive should be determined according to the accuracy of the equipment, the running speed and the actual condition of the base paper. Once the speed of the high-speed wide corrugated board production line reaches 200 m / min or more, the solid content of the adhesive must be high, water and The ratio of starch is usually between 2.5 : 1 and 3 : 1 .
The solid content of the adhesive is high, and the moisture is relatively reduced. The less the amount of sizing can ensure the adhesion of the corrugated board, and the change of moisture during the processing of the corrugated board is small, which can reduce the warpage of the corrugated board. If the precision of the enterprise equipment is low, the speed of the vehicle is slow, and the base paper is easy to penetrate, the solid content of the adhesive will be lower, otherwise the quality problems such as degumming, paste line and explosion of the corrugated board will be caused.
