When entering the factory, the moisture content of corrugated board should be in accordance with the GB13023 -
Test 91 specification.
Corrugated paper after the factory, should be to manipulate the storage temperature at room temperature.
Relative humidity is not greater than 40%.
Should be laminated on the ground, the ground should be moistureproof.
Storage time of 4.
Corrugated paper should not be too long.
Control the temperature and the temperature is in the process of the honeycomb cardboard production directly regulate water content of corrugated cardboard, guarantee the important condition of adhesive gel.
Therefore, when the honeycomb cardboard production line in the 80 m / 120 m/min, the general temperature should be manipulated in between 160 and 180, and saturated steam pressure of boiler should be control in 0.
9 mpa -
2 mpa, it not only can adjust the water content of corrugated paper honeycomb board and unilateral, but also to ensure that the gel gelation.
In order to ensure the strength of the honeycomb cardboard and good adhesion, depending on the honeycomb paperboard production line equipped with adjusting the structure of the honeycomb cardboard.
Is the manipulation of the corrugated board corrugated data ideal material moisture content is between 9% ~ 12%.
When moisture content is higher than the index of the corrugated paper, you can add a preheat area or fall after the speed to solve.
When the moisture content is below the index of the corrugated paper, can use the spray method.
Board of water content in the author's opinion, the original paper and corrugated paper is better, better moisture content of the original paper and corrugated paper, unilateral water content of honeycomb paperboard is not too much, but one side of the number of honeycomb paperboard is not too much overpasses.
Use paper, can add appropriately overpass on the number of single honeycomb cardboard.
The temperature of the dryer water content has a great influence of the honeycomb cardboard.
The heating part of the general of honeycomb paperboard production line is composed of three groups (
The number of the heating plate by heating plate size and speed of production line of honeycomb paperboard decision, each group has a separate control valve.
