Some points to pay attention to to ensure the moisture content of corrugated board-paper machine paper machine

　　Jinling Papermaking Equipment:

　　For the control of the moisture content of corrugated board, the following aspects should be controlled.

　　1. The moisture content of corrugated paper entering the factory should be inspected strictly in accordance with the GB13023-91 standard.

　　2. After entering the factory, the storage temperature of the corrugated base paper should be controlled at room temperature, and the relative humidity should not exceed 40%.

　　3. The storage of corrugated paper should be stacked vertically, and the ground should be moisture-proof.

　　4. The storage time of corrugated base paper should not be too long. Controlling the temperature in the corrugated board production process is an important condition for directly adjusting the moisture content of the corrugated paper and ensuring the gelatinization of the adhesive.

　　Therefore, when the corrugated board production line is between 80m/min and 120m/min, the temperature usually used should be controlled between 160℃～180℃, and the saturated steam pressure of the boiler should be controlled at 0.9Mpa-1.2Mpa according to its conversion. In this way, the moisture content of the corrugated base paper and single-faced corrugated board can be adjusted, and the gelatinization of the adhesive can be ensured.
