Observations on the machine behind the corrugated cardboard production line revealed that the adhesive strength of the single-sided or double-sided paperboard was very low with insufficient adhesion or no adhesion, and this adhesion was satisfactory at the time of corrugated board production. This observation is followed by a tile line, so this problem is different from the previously mentioned problems of loose corrugated, spot-bonded, or later-stubbed edge cardboard loose. The reason is mainly related to the quality of the original paper.

the reason

There is a noticeable water stain on the core paper, unlike the normal operation on the equipment

This abnormality occurs on high-gram or high-quality tissue paper

Measure

Reduce the viscosity of the paste (usually on a single-sided machine) at a suitable location Try to use another supplier's core paper and discuss the core paper problem with the original supplier

Because high-density or good-quality facial paper contains more fibers in a certain thickness, its heat transfer performance is also better than that of conventional plain paper. This problem should be solved by increasing the starch solids content and reducing the temperature of each part of the tile.
