Operation process of aluminum foil adhesive:
1. Clean the compound machine, pour the glue into the glue storage tank for recycling or directly add it into the glue tank. The temperature in the drying tunnel is 70-95 ℃, and the operating speed is about 30-50m/min.
2. Gluing amount is 5-10g/m2, 60% when air humidity is 25 ° C, and 16-20% when paper humidity is 25 ° C;
3. The remaining glue on both ends of the rubber roll will be rolled for a long time, and after curing, it will enter the glue tank, with the rubber roll, which may lead to irregular small particles on the composite paperboard. In order to prevent this phenomenon, circulating gluing shall be adopted, and about 200 mesh nylon filter cloth shall be used to bind the suction pump head of the circulating pump, so that the glue solution can be used after filtering.
4. If there are too many bubbles in the glue tank when the machine is started for a long time, which may cause partial glue shortage of the cots, the special defoamer of our factory can be used for spray defoaming or mixed before use.
5. In wet weather, if the humidity is too high and the curing speed of glue solution is too slow, the machine speed can be appropriately reduced or the drying temperature can be appropriately increased to adjust.
6. If the corners of the composite paperboard are cocked up, it may be caused by too much glue coating, resulting in too large shrinkage stress of the adhesive layer. Or due to the high moisture content of the paperboard itself, it should be properly controlled.
